    Dogs with hip dysplasia are commonly presented to veterinarians for evaluation. Although many causes of the condition have been proposed, a definitive cause has not been established. The multifactorial nature of canine hip dysplasia can confuse client education and management ofthe disease. The basic concept involved is the biomechanical imbalance between the forces on the coxofemoral joint and the associated muscle mass; the result is joint laxity in young, growing dogs. This laxity leads to incongruity; the eventual result is degenerative joint disease. Canine hip dysplasia can affect any breed but is most often reported in large and giant breeds. Understanding the pathophysiology and biomechanics involved with this developmental disease is important in providing clients with diagnostic, therapeutic, and prognostic information. The selection of treatment is influenced by the following factors:the age, health, and intended use of the patient; clinical signs; diagnostic findings; the availability of treatment; and the financial constraints of the owner. This article discusses the current concepts concerning the pathophysiology and biomechanics of canine hip dysplasia and outlines diagnostic and therapeutic options. The objective of the article is to provide practitioners with a reference for decision making and client education

    The advent of coronary angiography in the 1960s allowed for the risk stratification of patients with stable angina. Patients with unprotected left main coronary artery disease have an increased risk of death related to the large amount of myocardium supplied by this vessel. Although coronary angiography remains the preferred imaging modality for the evaluation of left main coronary artery stenosis, this technique has important limitations. Angiograms of the left main coronary artery segment can be difficult to interpret, and almost one-third of patients can be misclassified when fractional flow reserve is used as the reference. In patients with clinically significant unprotected left main coronary artery disease, surgical revascularization was shown to improve survival compared with medical therapy and has been regarded as the treatment of choice for unprotected left main coronary artery disease. Two large-scale clinical trials published in 2016 support the usefulness of catheter-based revascularization in selected patients with unprotected left main coronary artery disease. In this Review, we describe the pathophysiology of unprotected left main coronary artery disease, discuss diagnostic approaches in light of new noninvasive and invasive imaging techniques, and detail risk stratification models to aid the Heart Team in the decision-making process for determining the best revascularization strategy for these patients.

    Drug-induced heart and vascular disease remains an important health burden. Hydroxychloroquine and its predecessor chloroquine are medications commonly used in the treatment of systemic lupus erythematosus, rheumatoid arthritis, and other connective tissue disorders. Hydroxychloroquine interferes with malarial metabolites, confers immunomodulatory effects, and also affects lysosomal function. Clinical monitoring and early recognition of toxicity is an important management strategy in patients who undergo long-term treatment with hydroxychloroquine. Retinal toxicity, neuromyopathy, and cardiac disease are recognized adverse effects of hydroxychloroquine. Immediate withdrawal of hydroxychloroquine is essential if toxicity is suspected because of the early reversibility of cardiomyopathy. In addition to recommended ophthalmological screening, regular screening with 12-lead electrocardiogram and transthoracic echocardiography to detect conduction system disease and/or biventricular morphological or functional changes should be considered in hydroxychloroquine-treated patients. Cardiac magnetic resonance imaging and endomyocardial biopsy are valuable tools to provide prognostic insights and confirm the diagnosis of hydroxychloroquine-induced cardiomyopathy. In conclusion, chronic use of hydroxychloroquine can result in an acquired lysosomal storage disorder, leading to a drug-induced cardiomyopathy characterized by concentric hypertrophy and conduction abnormalities associated with increased adverse clinical outcomes and mortality.

    Full Text Available The purpose of this paper is to survey the literature on Gerbode defect and provide an overview of its history, anatomy, development, pathophysiology, diagnosis, and treatment options. The available literature on this topic, including case reports, was thoroughly reviewed. Gerbode defect is defined as abnormal shunting between the left ventricle and right atrium resulting from either a congenital defect or prior cardiac insults. The pathophysiology underlying the development of Gerbode defect is a disease process that injures the atrioventricular septum and leads to the abnormal shunting of blood. Although the most prevalent cause of Gerbode defect has historically been congenital, an increasing trend towards acquired cases has recently been reported owing to improved diagnostic capabilities and a greater number of invasive cardiac procedures. In conclusion, Gerbode defect is an increasingly recognized condition that warrants further study.

    This paper represents an international collaboration of paediatric endocrine and other societies (listed in the Appendix) under the International Consortium of Paediatric Endocrinology (ICPE) aiming to improve worldwide care of adolescent girls with polycystic ovary syndrome (PCOS)1. The manuscript examines pathophysiology and guidelines for the diagnosis and management of PCOS during adolescence. The complex pathophysiology of PCOS involves the interaction of genetic and epigenetic changes, primary ovarian abnormalities, neuroendocrine alterations, and endocrine and metabolic modifiers such as anti-Müllerian hormone, hyperinsulinemia, insulin resistance, adiposity, and adiponectin levels. Appropriate diagnosis of adolescent PCOS should include adequate and careful evaluation of symptoms, such as hirsutism, severe acne, and menstrual irregularities 2 years beyond menarche, and elevated androgen levels. Polycystic ovarian morphology on ultrasound without hyperandrogenism or menstrual irregularities should not be used to diagnose adolescent PCOS. Hyperinsulinemia, insulin resistance, and obesity may be present in adolescents with PCOS, but are not considered to be diagnostic criteria. Treatment of adolescent PCOS should include lifestyle intervention, local therapies, and medications. Insulin sensitizers like metformin and oral contraceptive pills provide short-term benefits on PCOS symptoms. There are limited data on anti-androgens and combined therapies showing additive/synergistic actions for adolescents. Reproductive aspects and transition should be taken into account when managing adolescents. © 2017 S. Karger AG, Basel.

    Chronic pruritus arises not only from dermatoses, but also, in up to half of cases, from extracutaneous origins. A multitude of systemic, neurological, psychiatric, and somatoform conditions are associated with pruritus in the absence of skin disease. Moreover, pruritus is a frequently observed side effect of many drugs. It is therefore difficult for physicians to make a correct diagnosis. Chronic pruritus patients frequently present to the dermatologist with skin lesions secondary to a long-lasting scratching behavior, such as lichenification and prurigo nodularis. A structured clinical history and physical examination are essential in order to evaluate the pruritus, along with systematic, medical history-adapted laboratory and radiological tests carried out according to the differential diagnosis. For therapeutic reasons, a symptomatic therapy should be promptly initiated parallel to the diagnostic procedures. Once the underlying factor(s) leading to the pruritus are identified, a targeted therapy should be implemented. Importantly, the treatment of accompanying disorders such as sleep disturbances or mental symptoms should be taken into consideration. Even after successful treatment of the underlying cause, pruritus may persist, likely due to chronicity processes including peripheral and central sensitization or impaired inhibition at spinal level. A vast arsenal of topical and systemic agents targeting these pathophysiological mechanisms has been used to deter further chronicity. The therapeutic options currently available are, however, still insufficient for many patients. Thus, future studies aiming to unveil the complex mechanisms underlying chronic pruritus and develop new therapeutic agents are urgently needed.

    Anemia coexists with inflammatory bowel disease (IBD) in up to two-thirds of patients, significantly impairing quality of life. The most common types of anemia in patients with IBD are iron deficiency anemia and anemia of chronic disease, which often overlap. In most cases, available laboratory tests allow successful diagnosis of iron deficiency, where difficulties appear, recently established indices such as soluble transferrin-ferritin ratio or percentage of hypochromic red cells are used. In this review, we discuss the management of the most common types of anemia in respect of the latest available data. Thus, we provide the mechanisms underlying pathophysiology of these entities; furthermore, we discuss the role of hepcidin in developing anemia in IBD. Next, we present the treatment options for each type of anemia and highlight the importance of individual choice of action. We also focus on newly developed intravenous iron preparations and novel, promising drug candidates targeting hepcidin. Concurrently, we talk about difficulties in differentiating between the true and functional iron deficiency, and discuss tools facilitating the process. Finally, we emphasize the importance of proper diagnosis and treatment of anemia in IBD. We conclude that management of anemia in patients with IBD is tricky, and appropriate screening of patients regarding anemia is substantial.

    Full Text Available Heart failure (HF with preserved left ventricular (LV ejection fraction (HFpEF occurs in 40 to 60% of the patients with HF, with a prognosis which is similar to HF with reduced ejection fraction (HFrEF. HFpEF pathophysiology is different from that of HFrEF, and has been characterized with diastolic dysfunction. Diastolic dysfunction has been defined with elevated left ventricular stiffness, prolonged iso-volumetric LV relaxation, slow LV filing and elevated LV end-diastolic pressure. Arterial hypertension occurs in majority cases with HFpEF worldwide. Patients are mostly older and obese. Diabetes mellitus and atrial fibrillation appear proportionally in a high frequency of patients with HFpEF. The HFpEF diagnosis is based on existence of symptoms and signs of heart failure, normal or approximately normal ejection and diagnosing of LV diastolic dysfunction by means of heart catheterization or Doppler echocardiography and/or elevated concentration of plasma natriuretic peptide. The present recommendations for HFpEF treatment include blood pressure control, heart chamber frequency control when atrial fibrillation exists, in some situations even coronary revascularization and an attempt for sinus rhythm reestablishment. Up to now, it is considered that no medication or a group of medications improve the survival of HFpEF patients. Due to these causes and the bad prognosis of the disorder, rigorous control is recommended of the previously mentioned precipitating factors for this disorder. This paper presents a universal review of the most important parameters which determine this disorder.

    Headache attributed to airplane travel, also named "airplane headache" (AH) is a headache that occurs during take-off and landing. Today, there are still uncertainties about the pathophysiology and treatment of AH. This systematic review was performed to facilitate identification of the existing literature on AH in order to discuss the current evidence and areas that remain to be investigated in AH. The systematic literature search was performed in 3 relevant medical databases; PubMed, Scopus, and Embase. The search yielded 220 papers and the papers were sorted based on inclusion and exclusion criteria established for this study. This systematic review included 39 papers. Main findings revealed that AH attacks are clinically stereotyped and appear mostly during landing phases. The headache presents as a severe painful headache that often disappears within 30 min. The pain is unilateral and localized in the fronto-orbital region. Sinus barotrauma has been considered as the main cause of AH. Nonsteroidal anti-inflammatory drugs and triptans have been taken by passengers with AH, to relieve the headache. Based on this systematic review, further studies seem required to investigate underlying mechanisms in AH and also to investigate the biological effects of nonsteroidal anti-inflammatory drugs and triptans for alleviating of AH. These studies would advance our understanding of AH pathogenesis and potential use of treatments that are not yet established.

    Similar to amblyopia in the visual system, "amblyaudia" is a term used to describe persistent hearing difficulty experienced by individuals with a history of asymmetric hearing loss (AHL) during a critical window of brain development. Few clinical reports have described this phenomenon and its consequent effects on central auditory processing. We aim to (1) define the concept of amblyaudia and (2) review contemporary research on its pathophysiology and emerging clinical relevance. PubMed, Embase, and Cochrane databases. A systematic literature search was performed with combinations of search terms: "amblyaudia," "conductive hearing loss," "sensorineural hearing loss," "asymmetric," "pediatric," "auditory deprivation," and "auditory development." Relevant articles were considered for inclusion, including basic and clinical studies, case series, and major reviews. During critical periods of infant brain development, imbalanced auditory input associated with AHL may lead to abnormalities in binaural processing. Patients with amblyaudia can demonstrate long-term deficits in auditory perception even with correction or resolution of AHL. The greatest impact is in sound localization and hearing in noisy environments, both of which rely on bilateral auditory cues. Diagnosis and quantification of amblyaudia remain controversial and poorly defined. Prevention of amblyaudia may be possible through early identification and timely management of reversible causes of AHL. Otolaryngologists, audiologists, and pediatricians should be aware of emerging data supporting amblyaudia as a diagnostic entity and be cognizant of the potential for lasting consequences of AHL. Prevention of long-term auditory deficits may be possible through rapid identification and correction. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Hyperparathyroidism exists in primary and secondary forms. Primary hyperparathyroidism has typically been considered a disease that uncommonly affects cats, but this condition is more prevalent than previous diagnoses would suggest. Secondary hyperparathyroidism may be caused by either nutritional influences (ie, nutritional secondary hyperparathyroidism) or chronic kidney disease (ie, renal secondary hyperparathyroidism). Tertiary hyperparathyroidism has yet to be documented in veterinary medicine, but it is possible that this condition occurs in some cats following longstanding renal secondary hyperparathyroidism. Diagnosis of this group of calcium metabolic disorders presents a number of challenges for the clinician. For example, clinical signs can be non-specific and, especially in the case of primary hyperparathyroidism, there is often a low index of suspicion for the disease; careful sample handling is required for testing of parathyroid hormone (PTH) and ionized calcium levels; and there is currently no feline-specific assay for PTH, which has implications for test sensitivity and interpretation of results. This article briefly outlines PTH and calcium physiology by way of introduction to a review of PTH measurement and interpretation. Various forms of feline hyperparathyroidism are then described, encompassing diagnosis and treatment options. © ISFM and AAFP 2015.

    2015-12-21

    Polycystic ovary syndrome (PCOS) is the most common cause of chronic anovulation and hyperandrogenism in young women. Excessive ovarian production of Anti-Müllerian Hormone, secreted by growing follicles in excess, is now considered as an important feature of PCOS. The aim of this review is first to update the current knowledge about the role of AMH in the pathophysiology of PCOS. Then, this review will discuss the improvement that serum AMH assay brings in the diagnosis of PCOS. Last, this review will explain the utility of serum AMH assay in the management of infertility in women with PCOS and its utility as a marker of treatment efficiency on PCOS symptoms. It must be emphasized however that the lack of an international standard for the serum AMH assay, mainly because of technical issues, makes it difficult to define consensual thresholds, and thus impairs the widespread use of this new ovarian marker. Hopefully, this should soon improve.

    Sepsis is a clinical syndrome that results from the dysregulated inflammatory response to infection that leads to organ dysfunction. The resulting losses to society in terms of financial burden, morbidity, and mortality are enormous. We provide a review of sepsis, its underlying pathophysiology, and guidance for diagnosis and management of this common disease. Current established treatments include appropriate antimicrobial agents to target the underlying infection, optimization of intravascular volume to improve stroke volume, vasopressors to counteract vasoplegic shock, and high-quality supportive care. Appropriate implementation of established treatments combined with novel therapeutic approaches promises to continue to decrease the impact of this disease.

    Antibody-mediated rejection (AMR), also known as B-cell-mediated or humoral rejection, is a significant complication after kidney transplantation that carries a poor prognosis. Although fewer than 10% of kidney transplant patients experience AMR, as many as 30% of these patients experience graft loss as a consequence. Although AMR is mediated by antibodies against an allograft and results in histologic changes in allograft vasculature that differ from cellular rejection, it has not been recognized as a separate disease process until recently. With an improved understanding about the importance of the development of antibodies against allografts as well as complement activation, significant advances have occurred in the treatment of AMR. The standard of care for AMR includes plasmapheresis and intravenous immunoglobulin that remove and neutralize antibodies, respectively. Agents targeting B cells (rituximab and alemtuzumab), plasma cells (bortezomib), and the complement system (eculizumab) have also been used successfully to treat AMR in kidney transplant recipients. However, the high cost of these medications, their use for unlabeled indications, and a lack of prospective studies evaluating their efficacy and safety limit the routine use of these agents in the treatment of AMR in kidney transplant recipients. © 2014 Pharmacotherapy Publications, Inc.

    The German Journal of Gastroenterology celebrates its fifties anniversary in 2013. Over half a century original studies, reviews and guidelines covering the topics of acute and chronic pancreatitis as well as pancreatic cancer have assumed a prominent role on its pages. Already in the first edition of the Journal Haemmerli and Hefti have summarized the Zurich experience with chronic pancreatitis and provided a detailed state-of-the-art review for the year 1963. 50 years later the current guidelines of the German Society of Digestive and Metabolic Diseases (DGVS) have been published in the same Journal and allow to summarize the scientific progress over this period. Back then chronic pancreatitis was regarded as a rare disorder (tenfold less common than e. g. acute pancreatitis or pancreatic cancer). This misconception had little to do with actual prevalence but with highly insensitive diagnostic tests, particularly in the area of diagnostic imaging. While pathogenetic factors for chronic pancreatitis, including a possible genetic disposition, were largely known in 1963, our understanding of their cellular mechanisms has very much improved. The greatest progress in diagnostic options was achieved by the introduction of novel imaging techniques such as ultrasound and endoscopic ultrasound, ERCP, CT and MRCP. In terms of therapy the notion that a blockage of pancreatitic secretion is an effective pharmacological option has been abandoned and endoscopic intervention and surgical treatment have been newly developed as alternatives. © Georg Thieme Verlag KG Stuttgart · New York.

  18. Preeclampsia: from Pathophysiology to Treatment

    2016-12-01

    Full Text Available Preeclampsia is a multisystem disorder unique to human pregnancy and is its most common glomerular complication. It occurs in 2% to 8% of pregnancies and is a major contributor to maternal mortality worldwide. Although the pathophysiology of this syndrome is not fully understood, many pathogenetic mechanisms are involved in this disorder. The role of the placenta is crucial in the development of this disorder. Some pathogenetic mechanisms involved in this disease comprise defective deep placentation, autoantibodies to type-1 angiotensin II receptor, endothelial dysfunction, oxidative stress, platelet and thrombin activation, intravascular inflammation, and the imbalance between angiogenic and antiangiogenic factors which is thought to be one of the most crucial mechanisms. Further understanding of the full picture could enhance our current knowledge of the pathogenesis of preeclampsia and improve its treatment. Thus, based on specific biomarkers the diagnosis and subclassification of preeclampsia might be more accurate in identifying patients at risk, monitoring disease progression and providing effective interventions

    2012-09-01

    Hypophosphatasia (HPP) is the inborn-error-of-metabolism caused by loss-of-function mutation(s) in the gene that encodes the tissue-nonspecific isozyme of alkaline phosphatase (TNAP). The disease has been classified according to patient age when the first signs and symptoms manifest; i.e., perinatal, infantile, childhood, adult HPP. Other types include odonto HPP and perinatal benign. Babies with the perinatal/infantile forms of HPP often die with severe rickets and respiratory insufficiency and sometimes hypercalcemia and vitamin B 6 -responsive seizures. The primary biochemical defect in HPP is a deficiency of TNAP activity that leads to elevated circulating levels of substrates, in particular inorganic pyrophosphate (PP i ), a potent calcification inhibitor. To-date, the management of HPP has been essentially symptomatic or orthopedic. However, enzyme replacement therapy with mineral-targeting TNAP (sALP-FcD 10 , also known as ENB-0040 or asfotase alfa) has shown promising results in a mouse model of HPP ( Alpl -/- mice). Administration of mineral-targeting TNAP from birth increased survival and prevented the seizures, rickets, as well as all the tooth abnormalities, including dentin, acellular cementum, and enamel defects in this model of severe HPP. Clinical trials using mineral-targeting TNAP in children 3 years of age or younger with life-threatening HPP was associated with healing of the skeletal manifestations of HPP as well as improved respiratory and motor function. Improvement is still being observed in the patients receiving continued asfotase alfa therapy, with more than 3 years of treatment in some children. Enzyme replacement therapy with asfotase alfa has to-date been successful in patients with life-threatening HPP.

    2017-06-01

    Anemia of chronic inflammation (ACI) is a frequently diagnosed anemia and portends an independently increased morbidity and poor outcome associated with multiple underlying diseases. The pathophysiology of ACI is multifactorial, resulting from the effects of inflammatory cytokines which both directly and indirectly suppress erythropoiesis. Recent advances in molecular understanding of iron metabolism provide strong evidence that immune mediators, such as IL-6, lead to hepcidin-induced hypoferremia, iron sequestration, and decreased iron availability for erythropoiesis. The role of hepcidin-ferroportin axis in the pathophysiology of ACI is stimulating the development of new diagnostics and targeted therapies. In this review, we present an overview of and rationale for inflammation-, iron-, and erythropoiesis-related strategies currently in development. © 2017 International Society for Hemodialysis.

    "Pain" is one of body defense mechanisms and crucial for the life support. However, orofacial pain such as myofascial pain syndrome, burning mouth syndrome and trigeminal neuralgia plays no part in body defense mechanisms and requires therapeutic intervention. Recent studies have indicated that plastic changes in the activities of trigeminal neurons, satellite glial cells in trigeminal ganglion, secondary neurons, microglia and astrocytes in trigeminal spinal subnucleus following orofacial inflammation and trigeminal nerve injury are responsible for orofacial pain mechanisms. Clinically, it is well known that the etiologic differential diagnosis which consists of careful history-taking and physical examination is essential for therapeutic decision in patients with orofacial pain. This report outlines the current knowledge on the pathophysiology, diagnosis, treatment of orofacial pain.

    Full Text Available Restless legs syndrome (RLS, a common neurological sensorimotor disorder in western countries, has gained more and more attention in Asian countries. The prevalence of RLS is higher in older people and females. RLS is most commonly related to iron deficiency, pregnancy and uremia. The RLS symptoms show a significant circadian rhythm and a close relationship to periodic limb movements (PLMs in clinical observations, while the pathophysiological pathways are still unknown. The diagnostic criteria have been revised in 2012 to improve the validity of RLS diagnosis. Recent studies have suggested an important role of iron decrease of brain in RLS pathophysiology. Dopaminergic (DA system dysfunction in A11 cell groups has been recognized long ago from clinical treatment and autopsy. Nowadays, it is believed that iron dysfunction can affect DA system from different pathways and opioids have a protective effect on DA system. Several susceptible single nucleotide polymorphisms such as BTBD9 and MEIS1, which are thought to be involved in embryonic neuronal development, have been reported to be associated with RLS. Several pharmacological and non-pharmacological treatment are discussed in this review. First-line treatments of RLS include DA agents and α2δ agonists. Augmentation is very common in long-term treatment of RLS which makes prevention and management of augmentation very important for RLS patients. A combination of different types of medication is effective in preventing and treating augmentation. The knowledge on RLS is still limited, the pathophysiology and better management of RLS remain to be discovered.

    Gabbard, Scott L.; Crowell, Michael D.

    2011-01-01

    Abdominal bloating is commonly reported by men and women of all ages. Bloating occurs in nearly all patients with irritable bowel syndrome, and it also occurs in patients with other functional and organic disorders. Bloating is frequently disturbing to patients and frustrating to clinicians, as effective treatments are limited and are not universally successful. Although the terms bloating and abdominal distention are often used interchangeably, these symptoms likely involve different pathophysiologic processes, both of which are still not completely understood. The goal of this paper is to review the pathophysiology, evaluation, and treatment of bloating and abdominal distention. PMID:22298969

    Hoffmann, Jan; May, Arne

    2018-01-01

    Cluster headache is a trigeminal autonomic cephalalgia characterised by extremely painful, strictly unilateral, short-lasting headache attacks accompanied by ipsilateral autonomic symptoms or the sense of restlessness and agitation, or both. The severity of the disorder has major effects on the patient's quality of life and, in some cases, might lead to suicidal ideation. Cluster headache is now thought to involve a synchronised abnormal activity in the hypothalamus, the trigeminovascular system, and the autonomic nervous system. The hypothalamus appears to play a fundamental role in the generation of a permissive state that allows the initiation of an episode, whereas the attacks are likely to require the involvement of the peripheral nervous system. Triptans are the most effective drugs to treat an acute cluster headache attack. Monoclonal antibodies against calcitonin gene-related peptide, a crucial neurotransmitter of the trigeminal system, are under investigation for the preventive treatment of cluster headache. These studies will increase our understanding of the disorder and perhaps reveal other therapeutic targets. Copyright © 2018 Elsevier Ltd. All rights reserved.

  11. Pathophysiology and Treatment of Alien Hand Syndrome

    Full Text Available Background: Alien hand syndrome (AHS is a disorder of involuntary, yet purposeful, hand movements that may be accompanied by agnosia, aphasia, weakness, or sensory loss. We herein review the most reported cases, current understanding of the pathophysiology, and treatments.Methods: We performed a PubMed search in July of 2014 using the phrases “alien hand syndrome,” “alien hand syndrome pathophysiology,” “alien hand syndrome treatment,” and “anarchic hand syndrome.” The search yielded 141 papers (reviews, case reports, case series, and clinical studies, of which we reviewed 109. Non‐English reports without English abstracts were excluded.Results: Accumulating evidence indicates that there are three AHS variants: frontal, callosal, and posterior. Patients may demonstrate symptoms of multiple types; there is a lack of correlation between phenomenology and neuroimaging findings. Most pathologic and functional imaging studies suggest network disruption causing loss of inhibition as the likely cause. Successful interventions include botulinum toxin injections, clonazepam, visuospatial coaching techniques, distracting the affected hand, and cognitive behavioral therapy.Discussion: The available literature suggests that overlap between AHS subtypes is common. The evidence for effective treatments remains anecdotal, and, given the rarity of AHS, the possibility of performing randomized, placebo‐controlled trials seems unlikely. As with many other interventions for movement disorders, identifying the specific functional impairments caused by AHS may provide the best guidance towards individualized supportive care.

    Uveitis is narrow-defined inflammation of the uvea, also clinically include all inflammatory conditions in the eye. Uveitis may occur as a consequence of various causes and background, such as autoimmune diseases, infections, and hematopoietic malignancy. We have to treat uveitis not only controlling the inflammation but also maintaining up the visual function of the eye because the most uveitis is chronic and relapsing inflammatory disorder. Behçét's disease is a systemic disease and results in loss of vision without adequate treatment. Behçét's disease was a representative of vision loss uveitis because Behçét's patient usually had treatment resistance of conventional treatment, such as colchicine and cyclosporine. However, biological therapy with TNF-α, which started from 2007, has revolutionized the treatment strategy of Behçét's disease. It is not too much to say that Behçét's patient is free from fear of vision loss by the dramatic decrease of ocular attach. Biological therapy is not approved as a treatment of uveitis except Behçét's disease. Some protracted cases of Sarcoidosis and Vogt-Koyanagi-Harada disease are resistant to corticosteroid therapy and require new treatment. In this review, we discuss the pathophysiology of uveitis and report new treatment of Behçét's disease by biological therapy.

    1990-01-01

    The sensitivity in the diagnosis of cerebrovascular diseases using radiotracers can be enhanced by the use of the acetazolamide test. In this paper we present and discuss some physiological and pathophysiological aspects of its mechanism. The physiological action of the carboanhydrase inhibitor is like the action of enhanced pCO 2 in the tissue, thus acting at the site of metabolic regulation. The reaction of the vascular bed is influenced in part by subcortical structures. Pathologically the reaction can be disturbed at first by an altered regulation with the vessels being mechanically intact, e.g. in hypoxia or transient ischemia. Secondly, the mechanics of the vessels may be not intact e.g., in atherosclerosis or surrounding edema. Lastly, the vessels have already dilated, e.g. poststenotically. All these facts have to be taken into consideration interpreting an acetazolamid test. (orig.) [de

    Full Text Available Postural tachycardia syndrome (POTS, characterized by orthostatic tachycardia in the absence of orthostatic hypotension, has been the focus of increasing clinical interest over the last 15 years 1. Patients with POTS complain of symptoms of tachycardia, exercise intolerance, lightheadedness, extreme fatigue, headache and mental clouding. Patients with POTS demonstrate a heart rate increase of ≥30 bpm with prolonged standing (5-30 minutes, often have high levels of upright plasma norepinephrine (reflecting sympathetic nervous system activation, and many patients have a low blood volume. POTS can be associated with a high degree of functional disability. Therapies aimed at correcting the hypovolemia and the autonomic imbalance may help relieve the severity of the symptoms. This review outlines the present understanding of the pathophysiology, diagnosis, and management of POTS.

    2016-01-01

    Mastocytosis is a term used to describe a heterogeneous group of disorders characterized by clonal proliferation of mast cells in various organs. The organ most often affected is the skin. Mastocytosis is a relatively rare disorder that affects both sexes equally. It can occur at any age, although it tends to appear in the first decade of life, or later, between the second and fifth decades. Our understanding of the pathophysiology of mastocytosis has improved greatly in recent years, with the discovery that somatic c-kit mutations and aberrant immunophenotypic features have an important role. The clinical manifestations of mastocytosis are diverse, and skin lesions are the key to diagnosis in most patients. Copyright © 2015 Elsevier España, S.L.U. and AEDV. All rights reserved.

    Full Text Available Peripheral blood cytopenia in children can be due to a variety of acquired or inherited diseases. Genetic disorders affecting a single hematopoietic lineage are frequently characterized by typical bone marrow findings such as lack of progenitors or maturation arrest in congenital neutropenia or a lack of megakaryocytes in congenital amegakaryocytic thrombocytopenia whereas antibody mediated diseases such as autoimmune neutropenia are associated with a rather unremarkable bone marrow morphology. In contrast, pancytopenia is frequently associated with a hypocellular bone marrow and the differential diagnosis includes acquired aplastic anemia, myelodysplastic syndrome, inherited bone marrow failure syndromes such as Fanconi anemia and dyskeratosis congenita and a variety of immunological disorders including hemophagocytic lymphohistiocytosis. Thorough bone marrow analysis is of special importance for the diagnostic work-up of most patients. Cellularity, cellular composition and dysplastic signs are the cornerstones of the differential diagnosis. Pancytopenia in the presence of a normo- or hypercellular marrow with dysplastic changes may indicate myelodysplastic syndrome. More challenging for the hematologist is the evaluation of the hypocellular bone marrow. Although aplastic anemia and hypocellular refractory cytopenia of childhood (RCC can reliably be differentiated on a morphological level the overlapping pathophysiology remains a significant challenge for the choice of the therapeutic strategy. Furthermore, inherited bone marrow failure syndromes are usually associated with the morphological picture of RCC and the recognition of these entities is essential as they often present a multisystem disease requiring different diagnostic and therapeutic approaches. This paper gives an overview over the different disease entities presenting with (pancytopenia, their pathophysiology, characteristic bone marrow findings and therapeutic approaches.

    Background Rhabdomyolysis is a complex medical condition involving the rapid dissolution of damaged or injured skeletal muscle. Methods This review focuses on the epidemiology, pathophysiology, causes, presentation, diagnosis, complications, management, and anesthetic considerations related to rhabdomyolysis. Results Any form of muscle damage––and by extension any entity that causes muscle damage––can initiate rhabdomyolysis. One of the most important treatment goals when rhabdomyolysis is suspected is avoiding acute kidney injury. Conclusion All clinicians should be aware of common causes, diagnosis, and treatment options. PMID:25829882

    Antiphospholipid antibody syndrome (APS) is an autoimmune acquired thrombophilia characterized by recurrent thrombosis and pregnancy morbidity in the presence of antiphospholipid antibodies (aPL). APS can be primary, if it occurs in the absence of any underlying disease, or secondary, if it is associated with another autoimmune disorder, most commonly systemic lupus erythematosus. The exact pathogenetic mechanism of APS is unknown, but different, not mutually exclusive, models have been proposed to explain how anti-PL autoantibodies might lead to thrombosis and pregnancy morbidity. Diagnosis of APS requires that a patient has both a clinical manifestation (arterial or venous thrombosis and/or pregnancy morbidity) and persistently positive aPL, but the clinical spectrum of the disease encompasses additional manifestations which may affect every organ and cannot be explained exclusively by a prothrombotic state. Treatment for aPL-positive patients is based on the patient's clinical status, presence of an underlying autoimmune disease, and history of thrombotic events. In case of aPL positivity without previous thrombotic events, the treatment is mainly focused on reduction of additional vascular risk factors, while treatment of patients with definite APS is based on long-term anticoagulation. Pregnancy complications are usually managed with low-dose aspirin in association with low molecular weight heparin. Refractory forms of APS could benefit from adding hydroxychloroquine and/or intravenous immunoglobulin to anticoagulation therapy. Promising novel treatments include anti-B cell monoclonal antibodies, new-generation anticoagulants, and complement cascade inhibitors. The objective of this review paper is to summarize the recent literature on APS from pathogenesis to current therapeutic options.

    Oropharyngeal and esophageal dysphagia are a frequent, but seldom diagnosed symptom of Parkinson's disease (PD). More than 80 % of patients with PD develop dysphagia during the course of their disease leading to a reduced quality of life, complicated medication intake, malnutrition and aspiration pneumonia, which is a major cause of death in PD. The underlying pathophysiology is poorly understood. Impaired dopaminergic and non-dopaminergic mechanisms of the cortical swallowing network as well as peripheral neuromuscular involvement have been suggested to contribute to its multifactorial genesis. Diagnostic screening methods include PD-specific questionnaires and a modified water test. Fiber optic endoscopic evaluation of swallowing (FEES) and videofluoroscopic swallowing study (VFSS), which complement each other, are the gold standard for evaluation of PD-related dysphagia. For evaluation of esophageal dysphagia, the high-resolution manometry (HRM) may be a helpful tool. In addition to dysphagia-specific treatment by speech and language therapists (SLTs), optimized dopaminergic medication is a meaningful therapeutic option. A promising novel method is intensive training of expiratory muscle strength (EMST). Deep brain stimulation does not seem to have a clinically relevant effect on swallowing function in PD. © Georg Thieme Verlag KG Stuttgart · New York.

    Rumination syndrome, characterised by the effortless, often repetitive, regurgitation of recently ingested food into the mouth, was originally described in children and in the developmentally disabled. It is now well-recognised that rumination syndrome occurs in patients of all ages and cognitive abilities. To review a scholarly review on our current understanding of the rumination syndrome. The review was conducted on the basis of a medline search to identify relevant publications pertaining to the pathophysiology, clinical diagnosis and management of rumination syndrome. The Rome III consensus established diagnostic criteria for rumination syndrome in adults, children and infants. A typical history can be highly suggestive but oesophageal (high resolution) manometry/impedance with ingestion of a meal may help to distinguish rumination syndrome from other belching/regurgitation disorders. The pathophysiology is incompletely understood, but involves a rise in intra-gastric pressure, generated by a voluntary, but often unintentional, contraction of the abdominal wall musculature, at a time of low pressure in the lower oesophageal sphincter, causing retrograde movement of gastric contents into the oesophagus. To date, controlled trials in the treatment rumination syndrome are lacking. The mainstay of treatment for rumination syndrome is explanation and behavioural treatment which consists of habit reversal techniques that compete with the urge to regurgitate. Chewing gum, prokinetics, baclofen and even antireflux surgery have been proposed as adjunctive therapies, but high quality studies are generally lacking. Rumination is an under-recognised condition with incompletely understood pathophysiology. Behavioural therapy seems effective, but controlled treatment trials are lacking. © 2011 Blackwell Publishing Ltd.

  4. Portal hypertension in schistosomiasis: pathophysiology and treatment

    Full Text Available In heavily infected young patients, there is a "non-congestive" phase of the disease with splenomegaly which can improve after chemoterapy. A strong correlation between hepatosplenic form and worm burden in young patients has been repeatedly shown. The pattern of vascular intrhepatic lesions seems to depend on two mechanisms: (a egg embolization, with a partial blocking of the portal vasculature; (b the appearance of small portal collaterals along the intrahepatic portal sistem. The role played by hepatitis B virus (HBV and C virus infections in the pathogenesis of liver lesions is variably considered. Selective arteriography shows a reduced diameter of hepatic artery with thin and arched branches outlining vascular gaps. A rich arterial network , as described in autopsy cases, is usually not seen in vivo, except after splenectomy or shunt surgery. An augmented hepatic arterial flow was demonstrated in infected animals. These facts suggest that the poor intrahepatic arterial vascularization demonstrated by selective arteriography in humans is due to a "functional deviation"of arterial blood to the splenic territory. The best results obtained in treatment of portal hypertension were: esophagogastric desvascularization and splenectomy (EGDS, although risk of rebleeding persists; classical (proximal splenorenal shunt (SRS should be abandoned; distal splenorenal shunt may complicate with hepatic encephalopaty, although later and in a lower percentage than in SRS. Propranolol is currently under investigation. In our Department, schistosomotic patients with esophageal varices bleeding are treated by EGDS and, if rebleeding occurs, by sclerosis of the varices.

    Aphasia, the loss or impairment of language caused by brain damage, is one of the most devastating cognitive impairments of stroke. Aphasia is present in 21-38% of acute stroke patients and is associated with high short- and long-term morbidity, mortality and expenditure. Recovery from aphasia is possible even in severe cases. While speech-language therapy remains the mainstay treatment of aphasia, the effectiveness of conventional therapies has not been conclusively proved. This has motivated attempts to integrate knowledge from several domains in an effort to plan more rational therapies and to introduce other therapeutic strategies, including the use of intensive language therapy and pharmacological agents. Several placebo-controlled trials suggest that piracetam is effective in recovery from aphasia when started soon after the stroke, but its efficacy vanishes in patients with chronic aphasia. Drugs acting on catecholamine systems (bromocriptine, dexamfetamine) have shown varying degrees of efficacy in case series, open-label studies and placebo-controlled trials. Bromocriptine is useful in acute and chronic aphasias, but its beneficial action appears restricted to nonfluent aphasias with reduced initiation of spontaneous verbal messages. Dexamfetamine improves language function in subacute aphasia and the beneficial effect is maintained in the long term, but its use is restricted to highly selected samples. Pharmacological agents operating on the cholinergic system (e.g. donepezil) have shown promise. Data from single-case studies, case series and an open-label study suggest that donepezil may have beneficial effects on chronic poststroke aphasia. Preliminary evidence suggests that donepezil is well tolerated and its efficacy is maintained in the long term. Randomised controlled trials of donepezil and other cholinergic agents in poststroke aphasia are warranted.

    2018-04-01

    Cluster headache is a primary headache disorder affecting up to 0.1% of the population. Patients suffer from cluster headache attacks lasting from 15 to 180 min up to 8 times a day. The attacks are characterized by the severe unilateral pain mainly in the first division of the trigeminal nerve, with associated prominent unilateral cranial autonomic symptoms and a sense of agitation and restlessness during the attacks. The male-to-female ratio is approximately 2.5:1. Experimental, clinical, and neuroimaging studies have advanced our understanding of the pathogenesis of cluster headache. The pathophysiology involves activation of the trigeminovascular complex and the trigeminal-autonomic reflex and accounts for the unilateral severe headache, the prominent ipsilateral cranial autonomic symptoms. In addition, the circadian and circannual rhythmicity unique to this condition is postulated to involve the hypothalamus and suprachiasmatic nucleus. Although the clinical features are distinct, it may be misdiagnosed, with patients often presenting to the otolaryngologist or dentist with symptoms. The prognosis of cluster headache remains difficult to predict. Patients with episodic cluster headache can shift to chronic cluster headache and vice versa. Longitudinally, cluster headache tends to remit with age with less frequent bouts and more prolonged periods of remission in between bouts.

    2016-07-01

    Herpetic infections have plagued humanity for thousands of years, but only recently have advances in antiviral medications and supportive treatments equipped physicians to combat the most severe manifestations of disease. Prompt recognition and treatment can be life-saving in the care of patients with herpes simplex-1 virus encephalitis, the most commonly identified cause of sporadic encephalitis worldwide. Clinicians should be able to recognize the clinical signs and symptoms of the infection and familiarize themselves with a rational diagnostic approach and therapeutic modalities, as early recognition and treatment are key to improving outcomes. Clinicians should also be vigilant for the development of acute complications, including cerebral edema and status epilepticus, as well as chronic complications, including the development of autoimmune encephalitis associated with antibodies to the N-methyl-D-aspartate receptor and other neuronal cell surface and synaptic epitopes. Herein, we review the pathophysiology, differential diagnosis, and clinical and radiological features of herpes simplex virus-1 encephalitis in adults, including a discussion of the most common complications and their treatment. While great progress has been made in the treatment of this life-threatening infection, a majority of patients will not return to their previous neurologic baseline, indicating the need for further research efforts aimed at improving the long-term sequelae.

    Sleep apnea, defined as a pathologic pause in breathing during sleep >10 s, promotes the progression of chronic heart failure and may be a predictor of poor prognosis. It causes, in fact, several mechanical, hemodynamic, chemical and inflammatory changes that negatively compromise cardiovascular homeostasis of heart failure patients. Sleep apnea is recognized as sleep apnea syndrome when specific symptoms, such as sleepiness and headache during the daytime and snoring, are present and is diagnosed with an overnight test called polysomnography. There are two different forms of sleep apnea, central and obstructive. Breathing is interrupted by the loss of respiratory drive and the lack of respiratory effort in the central form, which affects about 40-60% of heart failure patients. In obstructive sleep apnea, breathing stops when throat muscles relax, despite respiratory effort. This form affects about 3% of the general population, while it is present in at least 30% of heart failure patients. The diagnosis of sleep disorders in heart failure becomes very important to help patients adopting lifestyle changes and starting specific therapies to improve quality of life and retard the progression of chronic heart failure.

    2018-02-14

    This review aims to examine gender differences in both the epidemiology and pathophysiology of hypertension and to explore gender peculiarities on the effects of antihypertensive agents in decreasing BP and CV events. Men and women differ in prevalence, awareness, and control rate of hypertension in an age-dependent manner. Studies suggest that sex hormones changes play a pivotal role in the pathophysiology of hypertension in postmenopausal women. Estrogens influence the vascular system inducing vasodilatation, inhibiting vascular remodeling processes, and modulating the renin-angiotensin aldosterone system and the sympathetic system. This leads to a protective effect on arterial stiffness during reproductive age that is dramatically reversed after menopause. Data on the efficacy of antihypertensive therapy between genders are conflicting, and the underrepresentation of aged women in large clinical trials could influence the results. Therefore, further clinical research is needed to uncover potential gender differences in hypertension to promote the development of a gender-oriented approach to antihypertensive treatment.

    Sturge-Weber syndrome (SWS), also known as encephalotrigeminal angiomatosis, is a condition which includes leptomeningeal hemangioma, facial angiomatosis or nevus flammeus, and ocular changes. SWS can lead to severe complications of anterior segment involving conjunctiva and eyelids, whereas posterior segment of the eye may also be affected by diffuse choroidal hemorrhages. This article was written with the objectives to determine the pathophysiology, diagnosis, and treatment of glaucoma associated with this rare and challenging disorder. A detailed literature search was conducted on PubMed, EMBASE, Cochrane Library, and Google Scholar using the key words. Forty-five articles matched our inclusion criteria that were included in this systematic review. Glaucoma is the one of the commonest ocular manifestations of SWS. It is caused by anterior chamber malformations, increased pressure in the episcleral veins, and changes in ocular hemodynamics. Glaucoma associated with SWS is usually congenital but can develop adults as well. The treatment of glaucoma associated with SWS is quite challenging because of early-onset, severe visual field impairment at the time of diagnosis, and unresponsiveness to standard medical treatment. Several surgical procedures have been devised but the long-term control of the intraocular pressure and visual function remain unsatisfactory. Modifications in the filtration surgery techniques and use of newer anti-fibrotic agents have produced good control of intraocular pressure. Management of glaucoma associated with SWS is multi-dimensional and needs both medical and surgical interventions for better control. The treatment should be devised on case to case basis depending upon the intraocular pressure, stage of the disease, and type of glaucoma.

    2014-09-01

    Existing classifications of central nervous system sleep disorders do not often provide tools to diagnose the majority of patients complaining of sleep-related symptoms, nor always guide effective treatment. I present a novel classification system that completely separates clinical syndromes from anatomical localization, pathophysiology, and etiology. The clinical syndrome I present can describe the majority of patients, but can be fractionated into individual subgroups for further study. By then separating the anatomy and physiology from the symptoms, an avenue of research becomes available to study the different possible structures that regulate sleep, that may be damaged and cause syndromes of sleep dysfunction. Some of these may produce symptoms that overlap with narcolepsy and some may be distinct. Because the clinical syndrome should be distinguished from anatomy or physiology, I have proposed the term narcoleptiform syndrome for the clinical syndrome. The model also clearly separates etiology from anatomy in a classical neurological manner. This allows etiology, localization and symptoms to be studied separately. It is likely that different etiologies may produce damage in areas that produce similar syndromes. For example, in this model, different causes of damage to the orexin nucleus would result in the same clinical syndrome. This reinforces the concept of studying anatomy, symptoms and etiology separately. By studying the relationship of syndromes or symptoms to anatomic localization and pathophysiology, it should be possible to test novel approaches to treatment based on different underlying structure or function. For example, patients with lesions in the ventrolateral preoptic nucleus or the thalamic intralaminar nuclei may both present with insomnia symptoms but need different treatment; or they might present with symptoms overlapping narcolepsy (a narcoleptiform syndrome) yet need different treatment. In some cases, a single treatment may cross over

    Bassari, Ramez; Koea, Jonathan B

    2015-02-07

    To review the underlying pathophysiology and currently available treatments for pruritis associated with jaundice. English language literature was reviewed using MEDLINE, PubMed, EMBASE and clinicaltrials.gov for papers and trails addressing the pathophysiology and potential treatments for pruritis associated with jaundice. Recent advances in the understanding of the peripheral anatomy of itch transmission have defined a histamine stimulated pathway and a cowhage stimulated pathway with sensation conveyed centrally via the contralateral spinothalamic tract. Centrally, cowhage and histamine stimulated neurons terminate widely within the thalamus and sensorimotor cortex. The causative factors for itch in jaundice have not been clarified although endogenous opioids, serotonin, steroid and lysophosphatidic acid all play a role. Current guidelines for the treatment of itching in jaundice recommend initial management with biliary drainage where possible and medical management with ursodeoxycholic acid, followed by cholestyramine, rifampicin, naltrexone and sertraline. Other than biliary drainage no single treatment has proved universally effective. Pruritis associated with jaundice is a common but poorly understood condition for which biliary drainage is the most effective therapy. Pharmacological therapy has advanced but remains variably effective.

    Obsessive compulsive disorder is prevalent, disabling, incompletely understood, and often resistant to current therapies. Established treatments consist of specialized cognitive-behavioral psychotherapy and pharmacotherapy with medications targeting serotonergic and dopaminergic neurotransmission. However, remission is rare, and more than a quarter of OCD sufferers receive little or no benefit from these approaches, even when they are optimally delivered. New insights into the disorder, and new treatment strategies, are urgently needed. Recent evidence suggests that the ubiquitous excitatory neurotransmitter glutamate is dysregulated in OCD, and that this dysregulation may contribute to the pathophysiology of the disorder. Here we review the current state of this evidence, including neuroimaging studies, genetics, neurochemical investigations, and insights from animal models. Finally, we review recent findings from small clinical trials of glutamate-modulating medications in treatment-refractory OCD. The precise role of glutamate dysregulation in OCD remains unclear, and we lack blinded, well-controlled studies demonstrating therapeutic benefit from glutamate-modulating agents. Nevertheless, the evidence supporting some important perturbation of glutamate in the disorder is increasingly strong. This new perspective on the pathophysiology of OCD, which complements the older focus on monoaminergic neurotransmission, constitutes an important focus of current research and a promising area for the ongoing development of new therapeutics.

  17. Psychiatric manifestations of Graves' hyperthyroidism: pathophysiology and treatment options.

    Science.gov (United States)

    Bunevicius, Robertas; Prange, Arthur J

    2006-01-01

    Graves' disease is an autoimmune disorder that is the most common cause of hyperthyroidism. Other symptoms associated with the disease are goitre, ophthalmopathy, and psychiatric manifestations such as mood and anxiety disorders and, sometimes, cognitive dysfunction. Graves' hyperthyroidism may result in these latter manifestations via the induction of hyperactivity of the adrenergic nervous system. This review addresses the psychiatric presentations, and their pathophysiology and treatment, in patients with hyperthyroidism, based on literature identified by a PubMed/MEDLINE database search. Although the focus is on mental symptoms associated with Graves' disease, it is not always clear from the literature whether patients had Graves' disease: in some studies, the patients were thought to have Graves' disease based on clinical findings such as diffuse goitre or ophthalmopathy or on measurements of thyroid antibodies in serum; however, in other studies, no distinction was made between Graves' hyperthyroidism and hyperthyroidism from other causes. Antithyroid drugs combined with beta-adrenoceptor antagonists are the treatments of choice for hyperthyroidism, as well as for the psychiatric disorders and mental symptoms caused by hyperthyroidism. A substantial proportion of patients have an altered mental state even after successful treatment of hyperthyroidism, suggesting that mechanisms other than hyperthyroidism, including the Graves' autoimmune process per se and ophthalmopathy, may also be involved. When psychiatric disorders remain after restoration of euthyroidism and after treatment with beta-adrenoceptor antagonists, specific treatment for the psychiatric symptoms, especially psychotropic drugs, may be needed.

  18. Dysmotility in Esophageal Atresia: Pathophysiology, Characterization, and Treatment

    Science.gov (United States)

    Faure, Christophe; Righini Grunder, Franziska

    2017-01-01

    Esophageal dysmotility is almost universal after esophageal atresia (EA) repair and is mainly related to the developmental anomaly of the esophagus. Esophageal dysmotility is involved in the pathophysiology of numerous symptoms and comorbidities associated with EA such as gastroesophageal reflux disease, aspiration and respiratory complications, and symptoms of dysphagia and feeding disorders. High-resolution esophageal manometry (HREM) has facilitated the characterization of the dysmotility, but there is an incomplete correlation between symptoms and manometrical patterns. Impedance coupled to HREM should help to predict the clinical outcome and therefore personalize patient management. Nowadays, the management of esophageal dysmotility in patients with EA is essentially based on treatment of associated inflammation related to peptic or eosinophilic esophagitis. PMID:28620599

    2013-01-01

    Object Preterm infants are at risk for perinatal complications, including germinal matrix–intraventricular hemorrhage (IVH) and subsequent posthemorrhagic hydrocephalus (PHH). This review summarizes the current understanding of the epidemiology, pathophysiology, management, and outcomes of IVH and PHH in preterm infants. Methods The MEDLINE database was systematically searched using terms related to IVH, PHH, and relevant neurosurgical procedures to identify publications in the English medical literature. To complement information from the systematic search, pertinent articles were selected from the references of articles identifed in the initial search. Results This review summarizes the current knowledge regarding the epidemiology and pathophysiology of IVH and PHH, primarily using evidence-based studies. Advances in obstetrics and neonatology over the past few decades have contributed to a marked improvement in the survival of preterm infants, and neurological morbidity is also starting to decrease. The incidence of IVH is declining, and the incidence of PHH will likely follow. Currently, approximately 15% of preterm infants who suffer severe IVH will require permanent CSF diversion. The clinical presentation and surgical management of symptomatic PHH with temporary ventricular reservoirs (ventricular access devices) and ventriculosubgaleal shunts and permanent ventriculoperitoneal shunts are discussed. Preterm infants who develop PHH that requires surgical treatment remain at high risk for other related neurological problems, including cerebral palsy, epilepsy, and cognitive and behavioral delay. This review highlights numerous opportunities for further study to improve the care of these children. Conclusions A better grasp of the pathophysiology of IVH is beginning to impact the incidence of IVH and PHH. Neonatologists conduct rigorous Class I and II studies to advance the outcomes of preterm infants. The need for well-designed multicenter trials is

  20. Vitiligo: An Update on Pathophysiology and Treatment Options.

    Science.gov (United States)

    Speeckaert, Reinhart; van Geel, Nanja

    2017-12-01

    The pathophysiology of vitiligo is becoming increasingly clarified. In non-segmental vitiligo, early factors include activation of innate immunity, inflammasome activation, oxidative stress, and loss of melanocyte adhesion. Nonetheless, the main mechanism leading to non-segmental vitiligo involves an immune-mediated destruction of melanocytes. Anti-melanocyte-specific cytotoxic T cells exert a central role in the final effector stage. Genetic research revealed a multi-genetic inheritance displaying an overlap with other autoimmune disorders. However, some melanocyte-specific genes were also affected. Segmental vitiligo carries a different pathogenesis with most evidence indicating a mosaic skin disorder. Current management includes topical corticosteroids and immunomodulators. Narrow-band ultraviolet B can be used in patients not responding to topical treatment or in patients with extensive disease. Pigment cell transplantation offers an alternative for the treatment of segmental vitiligo or stable non-segmental lesions. Recent findings have revealed new targets for treatment that could lead to more efficient therapies. Targeted immunotherapy may halt the active immune pathways, although combination therapy may still be required to induce satisfying repigmentation. A recently established core set of outcome measures, new measurement instruments, and biomarker research pave the way for future standardized clinical trials.

  1. Hyperthyroidism: Diagnosis and Treatment.

    Science.gov (United States)

    Kravets, Igor

    2016-03-01

    Hyperthyroidism is an excessive concentration of thyroid hormones in tissues caused by increased synthesis of thyroid hormones, excessive release of preformed thyroid hormones, or an endogenous or exogenous extrathyroidal source. The most common causes of an excessive production of thyroid hormones are Graves disease, toxic multinodular goiter, and toxic adenoma. The most common cause of an excessive passive release of thyroid hormones is painless (silent) thyroiditis, although its clinical presentation is the same as with other causes. Hyperthyroidism caused by overproduction of thyroid hormones can be treated with antithyroid medications (methimazole and propylthiouracil), radioactive iodine ablation of the thyroid gland, or surgical thyroidectomy. Radioactive iodine ablation is the most widely used treatment in the United States. The choice of treatment depends on the underlying diagnosis, the presence of contraindications to a particular treatment modality, the severity of hyperthyroidism, and the patient's preference.

    Since more than 50 million people in the United States have allergies, knowledge of the management of allergic reactions in the dental office is extremely important. Appropriate care may range from a simple referral to a primary care physician to lifesaving measures implemented during acute anaphylactic reactions. The authors present a basic review of the pathophysiology of allergic reactions and provide information detailing the diagnosis and management of allergic reactions that may be encountered in the dental office. Utilizing this information, the dental practitioner and ancillary staff will have a thorough understanding of allergic reactions and be prepared to successfully identify and treat these reactions.

  3. Insights into pathophysiology of punding reveal possible treatment strategies.

    2010-06-01

    Punding is a stereotyped behavior characterized by an intense fascination with a complex, excessive, nongoal oriented, repetitive activity. Men tend to repetitively tinker with technical equipment such as radio sets, clocks, watches and car engines, the parts of which may be analyzed, arranged, sorted and cataloged but rarely put back together. Women, in contrast, incessantly sort through their handbags, tidy continuously, brush their hair or polish their nails. Punders are normally aware of the inapposite and obtuse nature of the behavior; however, despite the consequent self-injury, they do not stop such behavior. The most common causes of punding are dopaminergic replacement therapy in patients affected by Parkinson's disease (PD) and cocaine and amphetamine use in addicts. The vast majority of information about punding comes from PD cases. A critical review of these cases shows that almost all afflicted patients (90%) were on treatment with drugs acting mainly on dopamine receptors D1 and D2, whereas only three cases were reported in association with selective D2 and D3 agonists. Epidemiological considerations and available data from animal models suggest that punding, drug-induced stereotypies, addiction and dyskinesias all share a common pathophysiological process. Punding may be related to plastic changes in the ventral and dorsal striatal structures, including the nucleus accumbens, and linked to psychomotor stimulation and reward mechanisms. Possible management guidelines are proposed.

    2011-01-01

    Chronic perineal pain is the anorectal and perineal pain without underlying organic disease, anorectal or endopelvic, which has been excluded by careful physical examination, radiological and endoscopic investigations. A variety of neuromuscular disorders of the pelvic floor lead to the different pathological conditions such as anorectal incontinence, urinary incontinence and constipation of obstructed defecation, sexual dysfunction and pain syndromes. The most common functional disorders of the pelvic floor muscles, accompanied by perineal pain are levator ani syndrome, proctalgia fugax, myofascial syndrome and coccygodynia. In the diagnosis of these syndromes, contributing to a thorough history, physical examination, selected specialized investigations and the exclusion of organic disease with proctalgia is carried out. Accurate diagnosis of the syndromes helps in choosing an appropriate treatment and in avoiding unnecessary and ineffective surgical procedures, which often are performed in an attempt to alleviate the patient's symptoms.

    Zahodne, Laura B; Fernandez, Hubert H

    2008-01-01

    Psychotic symptoms in Parkinson's disease (PD) are relatively common and, in addition to creating a disturbance in patients' daily lives, have consistently been shown to be associated with poor outcome. Our understanding of the pathophysiology of psychosis in PD has expanded dramatically over the past 15 years, from an initial interpretation of symptoms as dopaminergic drug adverse effects to the current view of a complex interplay of extrinsic and disease-related factors.PD psychosis has unique clinical features, namely that it arises within a context of a clear sensorium and retained insight, there is relative prominence of visual hallucinations and progression occurs over time. PD psychosis tends to emerge later in the disease course, and disease duration represents one risk factor for its development. The use of anti-PD medications (particularly dopamine receptor agonists) has been the most widely identified risk factor for PD psychosis. Other risk factors discussed in the literature include older age, disease severity, sleep disturbance, cognitive impairment, dementia and/or depression.Recent efforts have aimed to explore the complex pathophysiology of PD psychosis, which is now known to involve an interaction between extrinsic, drug-related and intrinsic, disease-related components. The most important extrinsic factor is use of dopaminergic medication, which plays a prominent role in PD psychosis. Intrinsic factors include visual processing deficits (e.g. lower visual acuity, colour and contrast recognition deficits, ocular pathology and functional brain abnormalities identified amongst hallucinating PD patients); sleep dysregulation (e.g. sleep fragmentation and altered dream phenomena); neurochemical (dopamine, serotonin, acetylcholine, etc.) and structural abnormalities involving site-specific Lewy body deposition; and genetics (e.g. apolipoprotein E epsilon4 allele and tau H1H1 genotype). Preliminary reports have also shown a potential relationship

  7. Pathophysiology and treatment of pulmonary hypertension in sickle cell disease

    Castro, Oswaldo L.; Machado, Roberto F.

    2016-01-01

    Pulmonary hypertension affects ∼10% of adult patients with sickle cell disease (SCD), particularly those with the homozygous genotype. An increase in pulmonary artery systolic pressure, estimated noninvasively by echocardiography, helps identify SCD patients at risk for pulmonary hypertension, but definitive diagnosis requires right-heart catheterization. About half of SCD-related pulmonary hypertension patients have precapillary pulmonary hypertension with potential etiologies of (1) a nitric oxide deficiency state and vasculopathy consequent to intravascular hemolysis, (2) chronic pulmonary thromboembolism, or (3) upregulated hypoxic responses secondary to anemia, low O2 saturation, and microvascular obstruction. The remainder have postcapillary pulmonary hypertension secondary to left ventricular dysfunction. Although the pulmonary artery pressure in SCD patients with pulmonary hypertension is only moderately elevated, they have a markedly higher risk of death than patients without pulmonary hypertension. Guidelines for diagnosis and management of SCD-related pulmonary hypertension were published recently by the American Thoracic Society. Management of adults with sickle-related pulmonary hypertension is based on anticoagulation for those with thromboembolism; oxygen therapy for those with low oxygen saturation; treatment of left ventricular failure in those with postcapillary pulmonary hypertension; and hydroxyurea or transfusions to raise the hemoglobin concentration, reduce hemolysis, and prevent vaso-occlusive events that cause additional increases in pulmonary pressure. Randomized trials have not identified drugs to lower pulmonary pressure in SCD patients with precapillary pulmonary hypertension. Patients with hemodynamics of pulmonary arterial hypertension should be referred to specialized centers and considered for treatments known to be effective in other forms of pulmonary arterial hypertension. There have been reports that some of these treatments

    Dengue fever is a common tropical infection. This acute febrile illness can be a deadly infection in cases of severe manifestation, causing dengue hemorrhagic shock. In this brief article, I will summarize and discuss the diagnosis and treatment of this disease. For diagnosis of dengue, most tropical doctors make use of presumptive diagnosis; however, the definite diagnosis should be based on immunodiagnosis or viral study. Focusing on treatment, symptomatic and supportive treatment is the main therapeutic approach. The role of antiviral drugs in the treatment of dengue fever has been limited, but is currently widely studied.

    Full Text Available Relapse in multiple sclerosis (MS is defined as a neurologic deficit associated with an acute inflammatory demyelinating event that lasts at least 24 hours in the absence of fever and infection. Myelinoclasis and axonal transection occur in relapses. Diagnosis, prognosis, treatment, and many other features of the disease are directly related to the relapses. MS starts as the relapsing-remitting (RRMS form in 85% of patients. A large number of relapses in the first years, polysymptomatic relapses, and pyramidal system, brain stem, and spinal cord involvement are signs of a poor outcome. The average frequency of relapses is approximately one per year during the first years of RRMS. The frequency of relapses increases during systemic infections, psychological stress, and in the postpartum first 3 months. Seventy-five percent of relapses are monosymptomatic. Pseudo-relapses and paroxysmal symptoms are distinguished from relapses by their sudden onset, sudden termination, and shorter duration. Contrast enhancement is valuable in imaging, but undetectable in most relapses. The regression in the first few weeks of relapses is explained by reduction of the edema, and by remyelination in the following months. Relapses and their features are also among the main determinants of treatment. High-dose methylprednisolone and early treatment with adrenocorticotropic hormone reduce post-relapse disability and shorten the duration of relapses. Plasmapheresis is a good option for patients who do not respond to steroid treatment. Identification of relapses by patients and physicians, distinguishing them from imitators, proper evaluation, treatment when necessary, and monitoring the results are of great importance for patients with MS. The educational levels of patients and physicians regarding these parameters should be increased. Well-designed studies that evaluate the long-term effect of relapse treatment on disability are needed.

    Full Text Available A case report of fosinopril-induced angioedema of the intestine with a chronic course accompanied by multiple acute exacerbations is described. Angiotensin-converting enzyme (ACE inhibitor-induced angioedema of the intestine (AIAI occurs in a minority of patients taking an ACE inhibitor. The clinical presentation encompasses acute abdominal symptoms, pronounced bowel edema and ascites with occasional facial and/or oropharyngeal swelling. AIAI is diagnosed based on the temporal relationship between the symptomatic presentation and drug use, absence of alternative diagnoses including other causes of angioedema, and the prompt resolution of symptoms upon discontinuation of the ACE inhibitor. Prompt radiological investigation (abdominal computerized tomography and/or ultrasound is critical in making an early diagnosis and in preventing unnecessary surgical intervention. There is a female predominance of AIAI, which may reflect the interaction of estradiol with the various pathways involved in the pathophysiology of AIAI. Management of AIAI consists mainly of conservative measures and discontinuation of the ACE inhibitor. Angiotensin II receptor antagonists should not be considered as appropriate alternatives. Awareness and knowledge of AIAI are important because of the increasing use of ACE inhibitors, current delays in making the diagnosis, obvious management strategies once the diagnosis is made and the dysutility of alternative diagnoses, which may lead to considerable morbidity. AIAI must be considered in patients taking ACE inhibitors who develop gastrointestinal complaints irrespective of the duration of the therapy.

    The dumping syndrome is frequent in bariatric surgery. It is probably the most common syndrome following partial or complete gastrectomy. Its prevalence in partial gastrectomy can reach up to 50%, thus it can be a significant complication arising from some types of bariatric surgeries. Critical analysis on dumping syndrome, its pathophysiology, diagnosis and treatment. A literature review was performed using the key words: 'dumping syndrome', 'bariatric surgery' and 'rapid dumping syndrome'. Inclusion criteria were: books, original works, case reports and meta-analyzes, and the exclusion criterion was literature review. Concerning the publication time, articles were screened between 1960 and May 2015. The dumping syndrome is complication arising from obesity surgeries, but also can be a result of vagus nerve damage. Diagnosis is done primarily through the use of questionnaires based on scores. The Sigstad score and Arts survey are valid means for assessing the dumping syndrome. Initial therapy consists in the adoption of dietary measures, short acting drugs administration. A síndrome de dumping é frequente após operações bariátricas.

    2016-09-01

    There are currently no disease-modifying treatments for progressive supranuclear palsy (PSP) or corticobasal degeneration (CBD), and no approved pharmacological or therapeutic treatments that are effective in controlling their symptoms. The use of most pharmacological treatment options are based on experience in other disorders or from non-randomized historical controls, case series, or expert opinion. Levodopa may provide some improvement in symptoms of Parkinsonism (specifically bradykinesia and rigidity) in PSP and CBD; however, evidence is conflicting and where present, benefits are often negligible and short lived. In fact, "poor" response to levodopa forms part of the NINDS-SPSP criteria for the diagnosis of PSP and consensus criteria for the diagnosis of CBD (Lang Mov Disord. 20 Suppl 1:S83-91, 2005; Litvan et al. Neurology. 48:119-25, 1997; Armstrong et al. Neurology. 80(5):496-503, 2013). There is some evidence that intrasalivery gland botulinum toxin is useful in managing problematic sialorrhea and that intramuscular botulinum toxin and baclofen are helpful in reducing dystonia, including blepharospasm. Benzodiazepines may also be useful in managing dystonia. Myoclonus may be managed using levetiracetam and benzodiazepines. Pharmacological agents licensed for Alzheimer's disease (such as acetylcholinesterase inhibitors and N-Methyl-D-aspartate receptor antagonists) have been used off-label in PSP, CBD, and other tauopathies with the aim of improving cognition; however, there is limited evidence that they are effective and risk of adverse effects may outweigh benefits. The use of atypical antipsychotics for behavioural symptoms is not recommended in the elderly or those with demetia associated conditions and most antipsychotics will worsen Parkinsonism. Antidepressants may be useful for behavioral symptoms and depression but are often poorly tolerated due to adverse effects. In the absence of an effective drug treatment to target the underlying cause of

    Full Text Available Acute renal impairment is common in patients with chronic liver disease, occurring in approximately 19% of hospitalised patients with cirrhosis. A variety of types of renal impairment are recognised. The most important of these is the hepatorenal syndrome, a functional renal impairment due to circulatory and neurohormonal abnormalities that underpin cirrhosis. It is one of the most severe complications of cirrhosis with survival often measured in weeks to months. A variety of treatment options exist with early diagnosis and appropriate treatment providing the best hope for cure. This paper provides a comprehensive and up-to-date review of hepatorenal syndrome and lays out the topic according to the following sections: pathophysiology, historical developments, diagnostic criteria and limitations, epidemiology, precipitating factors, predictors, clinical and laboratory findings, prognosis, treatment options, prophylaxis, and conclusion.

    1993-11-01

    Tardive dyskinesia is defined as a syndrome consisting of abnormal, stereotypical involuntary movements usually of choreoathetoid type, principally affected the mouth, face, limbs and trunk, which occurs relatively late in the course of neuroleptic drug treatment and in the etiology of which the drug treatment is a necessary factor. Presently, the prevalence of tardive dyskinesia in the hospitalized patients in psychiatric hospitals in Japan is estimated to be 20-30%. Epidemiology, possible pathophysiology and symptomatology of tardive dyskinesia are briefly described. Differential diagnosis between this syndrome and other involuntary movements such as psychotic mannerism, senile orofacial dyskinesia, rabbit's syndrome, Pisa syndrome or Meige's syndrome is discussed. Several drugs to suppress involuntary movements of tardive dyskinesia are described. However, there appears to be no consistently reliable therapies for patients who develop the tardive dyskinesia. Treatment for this syndrome, other than neuroleptic withdrawal, are still uncertain.

    Gaucher disease (GD, ORPHA355) is a rare, autosomal recessive genetic disorder. It is caused by a deficiency of the lysosomal enzyme, glucocerebrosidase, which leads to an accumulation of its substrate, glucosylceramide, in macrophages. In the general population, its incidence is approximately 1/40,000 to 1/60,000 births, rising to 1/800 in Ashkenazi Jews. The main cause of the cytopenia, splenomegaly, hepatomegaly, and bone lesions associated with the disease is considered to be the infiltration of the bone marrow, spleen, and liver by Gaucher cells. Type-1 Gaucher disease, which affects the majority of patients (90% in Europe and USA, but less in other regions), is characterized by effects on the viscera, whereas types 2 and 3 are also associated with neurological impairment, either severe in type 2 or variable in type 3. A diagnosis of GD can be confirmed by demonstrating the deficiency of acid glucocerebrosidase activity in leukocytes. Mutations in the GBA1 gene should be identified as they may be of prognostic value in some cases. Patients with type-1 GD-but also carriers of GBA1 mutation-have been found to be predisposed to developing Parkinson's disease, and the risk of neoplasia associated with the disease is still subject to discussion. Disease-specific treatment consists of intravenous enzyme replacement therapy (ERT) using one of the currently available molecules (imiglucerase, velaglucerase, or taliglucerase). Orally administered inhibitors of glucosylceramide biosynthesis can also be used (miglustat or eliglustat).

    Cancer patients who develop bone metastases are an estimated 60 to 84% . Of these 79% experienced pain syndromes are difficult to manage, of which 50% die without adequate pain relief and with a poor quality of life. Therefore, it is necessary to have accessible and effective medications for the management of this condition. The pathophysiology of pain in bone is reviewed and the drugs used most frequently in the management of this type of cancer pain are described. Furthermore an algorithm of 6 steps is presented and can guide the physician when making a therapeutic decision. (author) [es

  3. Laryngopharyngeal Reflux: Diagnosis, Treatment, and Latest Research

    Directory of Open Access Journals (Sweden)

    Campagnolo, Andrea Maria

    2014-01-01

    Full Text Available Introduction Laryngopharyngeal reflux (LPR is a highly prevalent disease and commonly encountered in the otolaryngologist's office. Objective To review the literature on the diagnosis and treatment of LPR. Data Synthesis LPR is associated with symptoms of laryngeal irritation such as throat clearing, coughing, and hoarseness. The main diagnostic methods currently used are laryngoscopy and pH monitoring. The most common laryngoscopic signs are redness and swelling of the throat. However, these findings are not specific of LPR and may be related to other causes or can even be found in healthy individuals. Furthermore, the role of pH monitoring in the diagnosis of LPR is controversial. A therapeutic trial with proton pump inhibitors (PPIs has been suggested to be cost-effective and useful for the diagnosis of LPR. However, the recommendations of PPI therapy for patients with a suspicion of LPR are based on the results of uncontrolled studies, and high placebo response rates suggest a much more complex and multifactorial pathophysiology of LPR than simple acid reflux. Molecular studies have tried to identify biomarkers of reflux such as interleukins, carbonic anhydrase, E-cadherin, and mucin. Conclusion Laryngoscopy and pH monitoring have failed as reliable tests for the diagnosis of LPR. Empirical therapy with PPIs is widely accepted as a diagnostic test and for the treatment of LPR. However, further research is needed to develop a definitive diagnostic test for LPR.

    Refeeding syndrome is a life-threatening complication that may occur after initiation of nutritional therapy in malnourished patients, as well as after periods of fasting and hunger. Refeeding syndrome can be effectively prevented and treated if its risk factors and pathophysiology are known. The initial measurement of thiamine level and serum electrolytes, including phosphate and magnesium, their supplementation if necessary, and a slow increase in nutritional intake along with close monitoring of serum electrolytes play an important role. Since refeeding syndrome is not well known and the symptoms can be extremely heterogeneous, this complication is poorly recognized, especially against the background of severe disease and multimorbidity. This overview aims to summarize the current knowledge and increase awareness about refeeding syndrome.

    Thyroid hormone has important physiologic functions in nearly every organ system. The critical role of thyroid hormone in growth and in physical and neurologic development lends particular importance to the prompt diagnosis and appropriate treatment of hypothyroidism in infants and children. Congenital hypothyroidism is common and has potentially devastating neurologic consequences. While the approach to diagnosis and treatment of severe congenital hypothyroidism is well established, data continue to emerge about the genetic causes, clinical significance, and prognosis of the milder forms of congenital hypothyroidism that are increasingly being diagnosed by newborn screening. Similarly, the diagnosis and treatment of severe acquired hypothyroidism is straightforward and clearly of clinical benefit, but uncertainty remains about the optimal management of mild subclinical hypothyroidism. This review summarizes current knowledge of the causes, clinical manifestations, diagnosis, treatment, and prognosis of hypothyroidism in infants and children, with a focus on recent developments and areas of uncertainty in this field.

    2017-01-01

    Full Text Available Hydrocephalus (HCP is a common complication in patients with subarachnoid hemorrhage. In this review, we summarize the advanced research on HCP and discuss the understanding of the molecular originators of HCP and the development of diagnoses and remedies of HCP after SAH. It has been reported that inflammation, apoptosis, autophagy, and oxidative stress are the important causes of HCP, and well-known molecules including transforming growth factor, matrix metalloproteinases, and iron terminally lead to fibrosis and blockage of HCP. Potential medicines for HCP are still in preclinical status, and surgery is the most prevalent and efficient therapy, despite respective risks of different surgical methods, including lamina terminalis fenestration, ventricle-peritoneal shunting, and lumbar-peritoneal shunting. HCP remains an ailment that cannot be ignored and even with various solutions the medical community is still trying to understand and settle why and how it develops and accordingly improve the prognosis of these patients with HCP.

  9. Hyperthyroidism: diagnosis and treatment.

    Reid, Jeri R; Wheeler, Stephen F

    2005-08-15

    The proper treatment of hyperthyroidism depends on recognition of the signs and symptoms of the disease and determination of the etiology. The most common cause of hyperthyroidism is Graves' disease. Other common causes include thyroiditis, toxic multinodular goiter, toxic adenomas, and side effects of certain medications. The diagnostic workup begins with a thyroid-stimulating hormone level test. When test results are uncertain, measuring radionuclide uptake helps distinguish among possible causes. When thyroiditis is the cause, symptomatic treatment usually is sufficient because the associated hyperthyroidism is transient. Graves' disease, toxic multinodular goiter, and toxic adenoma can be treated with radioactive iodine, antithyroid drugs, or surgery, but in the United States, radioactive iodine is the treatment of choice in patients without contraindications. Thyroidectomy is an option when other treatments fail or are contraindicated, or when a goiter is causing compressive symptoms. Some new therapies are under investigation. Special treatment consideration must be given to patients who are pregnant or breastfeeding, as well as those with Graves' ophthalmopathy or amiodarone-induced hyperthyroidism. Patients' desires must be considered when deciding on appropriate therapy, and dose monitoring is essential.

  10. Patellar Tendinopathy: Diagnosis and Treatment.

    Figueroa, David; Figueroa, Francisco; Calvo, Rafael

    2016-12-01

    Patellar tendinopathy is a common cause of pain in athletes' knees. Historically, it has been related to jumping sports, such as volleyball and basketball. Repetitive jumping generates a considerable load of energy in the extensor mechanism, leading to symptoms. The main pathophysiologic phenomenon in patellar tendinopathy is tendinosis, which is a degenerative disorder rather than an inflammatory disorder; therefore, the other popular term for this disease, tendinitis, is not appropriate. The nonsurgical treatment of patellar tendinopathy is focused on eccentric exercises and often has good results. Other experimental options, with variable levels of evidence, are available for recalcitrant cases. Surgical treatment is indicated for cases that are refractory to nonsurgical treatment. Open or arthroscopic surgery can be performed; the two methods are comparable, but arthroscopic surgery results in a faster recovery time.

    2014-08-15

    Impetigo is the most common bacterial skin infection in children two to five years of age. There are two principal types: nonbullous (70% of cases) and bullous (30% of cases). Nonbullous impetigo, or impetigo contagiosa, is caused by Staphylococcus aureus or Streptococcus pyogenes, and is characterized by honey-colored crusts on the face and extremities. Impetigo primarily affects the skin or secondarily infects insect bites, eczema, or herpetic lesions. Bullous impetigo, which is caused exclusively by S. aureus, results in large, flaccid bullae and is more likely to affect intertriginous areas. Both types usually resolve within two to three weeks without scarring, and complications are rare, with the most serious being poststreptococcal glomerulonephritis. Treatment includes topical antibiotics such as mupirocin, retapamulin, and fusidic acid. Oral antibiotic therapy can be used for impetigo with large bullae or when topical therapy is impractical. Amoxicillin/clavulanate, dicloxacillin, cephalexin, clindamycin, doxycycline, minocycline, trimethoprim/sulfamethoxazole, and macrolides are options, but penicillin is not. Natural therapies such as tea tree oil; olive, garlic, and coconut oils; and Manuka honey have been anecdotally successful, but lack sufficient evidence to recommend or dismiss them as treatment options. Treatments under development include minocycline foam and Ozenoxacin, a topical quinolone. Topical disinfectants are inferior to antibiotics and should not be used. Empiric treatment considerations have changed with the increasing prevalence of antibiotic-resistant bacteria, with methicillin-resistant S. aureus, macrolide-resistant streptococcus, and mupirocin-resistant streptococcus all documented. Fusidic acid, mupirocin, and retapamulin cover methicillin-susceptible S. aureus and streptococcal infections. Clindamycin proves helpful in suspected methicillin-resistant S. aureus infections. Trimethoprim/sulfamethoxazole covers methicillin-resistant S

    2016-01-01

    Plague still poses a significant threat to human health and as a reemerging infection is unfamiliar to the majority of the modern medical doctors. In this chapter, the plague is described according to Dr. Nikiforov's experiences in the diagnosis and treatment of patients, and also a review of the relevant literature on this subject is provided. The main modern methods and criteria for laboratory diagnosis of plague are briefly described. The clinical presentations include the bubonic and pneumonic form, septicemia, rarely pharyngitis, and meningitis. Early diagnosis and the prompt initiation of treatment reduce the mortality rate associated with bubonic plague and septicemic plague to 5-50 %; although a delay of more than 24 h in the administration of antibiotics and antishock treatment can be fatal for plague patients. Most human cases can successfully be treated with antibiotics.

    Haw, Alexandra; Palevsky, Harold I

    2018-04-01

    Pulmonary hypertension has emerged as a major cause of morbidity and mortality in patients with hemoglobinopathies and chronic hemolytic anemias. These hematological diseases include - but are not limited to - sickle cell disease (SCD), thalassemia, paroxysmal nocturnal hematuria, and hereditary spherocytosis. Although most studies have been based on the use of echocardiography as a screening tool for pulmonary hypertension as opposed to the gold standard of right heart catheterization for definitive diagnosis, the association between chronic hemolytic anemia and pulmonary hypertension is evident. Studies have shown that patients with SCD and a tricuspid regurgitant velocity (TRV) ≥ 2.5 m/sec are at increased risk of pulmonary hypertension and are at increased mortality risk. Additional markers of risk of pulmonary hypertension and increased mortality include a pro-BNP >160 pg/mL combined with a 6-min walk distance of pulmonary hypertension in chronic hemolytic anemias.

    Chronic subdural hematoma (CSDH) is one of the more frequent pathologic entities in daily neurosurgical practice. Historically, CSDH was considered progressive recurrent bleeding with a traumatic cause. However, recent evidence has suggested a complex intertwined pathway of inflammation, angiogenesis, local coagulopathy, recurrent microbleeds, and exudates. The aim of the present review is to collect existing data on pathophysiology of CSDH to direct further research questions aiming to optimize treatment for the individual patient. We performed a thorough literature search in PubMed, Ovid, EMBASE, CINAHL, and Google scholar, focusing on any aspect of the pathophysiology and nonsurgical treatment of CSDH. After a (minor) traumatic event, the dural border cell layer tears, which leads to the extravasation of cerebrospinal fluid and blood in the subdural space. A cascade of inflammation, impaired coagulation, fibrinolysis, and angiogenesis is set in motion. The most commonly used treatment is surgical drainage. However, because of the pathophysiologic mechanisms, the mortality and high morbidity associated with surgical drainage, drug therapy (dexamethasone, atorvastatin, tranexamic acid, or angiotensin-converting enzyme inhibitors) might be a beneficial alternative in many patients with CSDH. Based on pathophysiologic mechanisms, animal experiments, and small patient studies, medical treatment may play a role in the treatment of CSDH. There is a lack of level I evidence in the nonsurgical treatment of CSDH. Therefore, randomized controlled trials, currently lacking, are needed to assess which treatment is most effective in each individual patient. Copyright © 2018 The Author(s).

    2014-12-01

    Full Text Available The practice of extreme sports is becoming more and more common. Despite physiological adaptation, people who intensively exercise are exposed to exercise-associated complications, including hyponatraemia. Exercise-associated hyponatraemia seems to be a consequence of alteration of water regulation, particularly by excessive expression of vasopressin, sodium mobilisation, and interleukin-6 production by muscular cells. Preventing overhydration, both before and during effort, and prohibiting hypotonic solutes during treatment are the leading interventions to correct hyponatraemia.

    Under physiological conditions, excessive loss of water through the urine is prevented by the release of the antidiuretic hormone arginine-vasopressin (AVP) from the posterior pituitary. In the kidney, AVP elicits a number of cellular responses, which converge on increasing the osmotic reabsorption of water in the collecting duct. One of the key events triggered by the binding of AVP to its type-2 receptor (AVPR2) is the exocytosis of the water channel aquaporin 2 (AQP2) at the apical membrane the principal cells of the collecting duct. Mutations of either AVPR2 or AQP2 result in a genetic disease known as nephrogenic diabetes insipidus, which is characterized by the lack of responsiveness of the collecting duct to the antidiuretic action of AVP. The affected subject, being incapable of concentrating the urine, presents marked polyuria and compensatory polydipsia and is constantly at risk of severe dehydration. The molecular bases of the disease are fully uncovered, as well as the genetic or clinical tests for a prompt diagnosis of the disease in newborns. A real cure for nephrogenic diabetes insipidus (NDI) is still missing, and the main symptoms of the disease are handled with s continuous supply of water, a restrictive diet, and nonspecific drugs. Unfortunately, the current therapeutic options are limited and only partially beneficial. Further investigation in vitro or using the available animal models of the disease, combined with clinical trials, will eventually lead to the identification of one or more targeted strategies that will improve or replace the current conventional therapy and grant NDI patients a better quality of life. Here we provide an updated overview of the genetic defects causing NDI, the most recent strategies under investigation for rescuing the activity of mutated AVPR2 or AQP2, or for bypassing defective AVPR2 signaling and restoring AQP2 plasma membrane expression.

    Osteoarthritis (OA) is a disease of the joint, and age is the major risk factor for its development. Clinical manifestation of OA includes joint pain, stiffness, and loss of mobility. Currently, no pharmacological treatments are available to treat this specific joint disease; only symptom-modifying drugs are available. Improvement in imaging technology, identification of biomarkers, and increased understanding of the molecular basis of OA will aid in detecting the early stages of disease. Yet the development of interventional strategies remains elusive and will be critical for effective prevention of OA-associated joint destruction. The potential of cell-based therapies may be applicable in improving joint function in mild to more advanced cases of OA. Ongoing studies to understand the basis of this disease will eventually lead to prevention and treatment strategies and will also be a key in reducing the social and economic burden of this disease. Nurses are advised to provide an integrative approach of disease assessment and management in OA patients' care with a focus on education and implementation. Knowledge and understanding of OA and how this affects the individual patient form the basis for such an integrative approach to all-round patient care and disease management.

    1985-07-01

    Pathologic anxiety, marked by inappropriate apprehension and/or fear, causes patients to seek help. Anxiety is associated with a wide variety of physical illnesses, and these must be initially considered when making a diagnosis. Similarly, anxiety associated with a wide variety of psychiatric syndromes must also be considered. Finally, the possibility of transient situational anxiety is ever present. Once it is determined that a primary anxiety disorder exists, then the presence or absence of phobias, panic attacks, and chronic "free-floating" anxiety will fully characterize the disorder. With an accurate diagnosis in hand, a multifaceted treatment approach can be designed. Effective treatments now exist for phobic and panic disorders, and more effective treatment for chronic generalized anxiety may be forthcoming.

    2012-05-01

    Published evidence on established and theoretical connections between immune system dysfunction and schizophrenia is reviewed, with a discussion of developments in the search for immunologically-targeted treatments. A growing body of evidence indicates that immunologic influences may play an important role in the etiology and course of schizophrenia. A literature search identified more than 100 articles pertaining to suspected immunologic influences on schizophrenia published over the past 15 years. Schizophrenia researchers have explored a wide range of potential immune system-related causal or contributory factors, including neurobiological and neuroanatomical disorders, genetic abnormalities, and environmental influences such as maternal perinatal infection. Efforts to establish an immunologic basis for schizophrenia and identify reliable immune markers continue to be hindered by sampling challenges and methodological problems. In aggregate, the available evidence indicates that at least some cases of schizophrenia have an immunologic component, suggesting that immune-focused prevention strategies (e.g., counseling of pregnant women to avoid immune stressors) and close monitoring of at-risk children are appropriate. While antipsychotics remain the standard treatments for schizophrenia, a variety of drugs with immunologic effects have been investigated as adjunctive therapies, with variable and sometimes conflicting results; these include the cyclooxygenase-2 inhibitor celecoxib, immune-modulating agents (e.g., azathioprine and various anticytokine agents such as atlizumab, anakinra, and tumor necrosis factor-α blockers), and an investigational anti-interferon-γ agent. The published evidence indicates that immune system dysfunction related to genetic, environmental, and neurobiological influences may play a role in the etiology of schizophrenia in a subset of patients.

  8. [Understanding the pathophysiology of malnutrition for better treatment].

    De Bandt, J-P

    2015-09-01

    Malnutrition results from an imbalance between intake and protein-energy requirements resulting in tissue losses with adverse functional consequences. However, it would be better to speak of "states of malnutrition" rather than "malnutrition". Indeed, the mechanisms involved associate, with varying degrees, intake deficiency and increased needs with different clinical consequences. Adaptation to nutrient deficiency aims at establishing lasting saving conditions by promoting optimization of energy reserve utilization while preserving protein pool. This is achieved by reducing basal metabolism (low T3), by decreasing the secretion of anabolic factors and moderately increasing catabolic hormones. Unlike the previous process, the metabolic response to injury or stress, which will sometime induce major increase in requirements, will have as immediate purpose the defense of the organism. The body will draw sometime substantially in its protein pool to produce the glucose required for example by the immune cells. Stress response stems from both an endocrine response, and an immuno-inflammatory one with the important role of pro-inflammatory cytokines released in response to pathogens and more recently alarmins in response to endogenous stress in the inflammatory phenomena of the stress response and in the resulting malnutrition state. Treatment of these malnutrition conditions will thus differ: promoting anabolism in one case and fighting resistance to anabolism and hypercatabolism in the other.

    The basic data on hyperprolactinemia (i.e. an excess of PRL above a reference laboratory's upper limits), the most common endocrine disorder of the hypothalamic-pituitary axis are given in this review. The following issues are discussed: regulation of prolactin (Prl) secretion, definition of hyperprolactinemia, its etiology and pathogenesis as well as its symptoms, diagnosis, and treatment (including medical and surgical therapy). It should be stressed that finding of elevated PRL serum concentrations constitute the beginning of diagnostic procedure and, after exclusion of physiologic, pharmacologic, and other organic causes of increased PRL levels, should be followed by detailed diagnosis including MRI. In patients in whom hyperprolactinemia has been confirmed the treatment with dopamine agonists (with prevalence of cabergoline, followed by quinagoline) is currently considered first-choice therapy. Surgery should be performed only in the patients resistant or intolerant to these agents, or in patients who refuse long-term therapy. (author)

    Full Text Available Neurocysticercosis, the infection caused by the larval form of the tapeworm Taenia solium, is the most common parasitic disease of the central nervous system and the most common cause of acquired epilepsy worldwide. This has primarily been a disease that remains endemic in low-socioeconomic countries, but because of increased migration neurocysticercosis is being diagnosed more frequently in high-income countries. During the past three decades improved diagnostics, imaging, and treatment have led to more accurate diagnosis and improved prognosis for patients. This article reviews the current literature on neurocysticercosis, including newer diagnostics and treatment developments.

    Here we summarize the diagnosis of osteogenesis imperfecta, discuss newly discovered genes involved in osteogenesis imperfecta, and review the management of this disease in children and adults. Mutations in the two genes coding for collagen type I, COL1A1 and COL1A2, are the most common cause of osteogenesis imperfecta. In the past 10 years, defects in at least 17 other genes have been identified as responsible for osteogenesis imperfecta phenotypes, with either dominant or recessive transmission. Intravenous bisphosphonate infusions are the most widely used medical treatment. This has a marked effect on vertebra in growing children and can lead to vertebral reshaping after compression fractures. However, bisphosphonates are less effective for preventing long-bone fractures. At the moment, new therapies are under investigation. Despite advances in the diagnosis and treatment of osteogenesis imperfecta, more research is needed. Bisphosphonate treatment decreases long-bone fracture rates, but such fractures are still frequent. New antiresorptive and anabolic agents are being investigated but efficacy and safety of these drugs, especially in children, need to be better established before they can be used in clinical practice.

    Full Text Available Sarcopenia is defined as the age-related loss of skeletal muscle mass and decline of function. The causes of sarcopenia are multi-factorial. The diagnosis of sarcopenia should be considered in all older patients who present with declines in physical function, because of potential consequences for the development of frailty and disability. There are numerous techniques to assess muscle mass, muscle strength and physical performance. Treatment consists of nutritional (macro- and micronutrients and physical activity (resistance exercise regimens adapted to person. There is an emerging role for testosterone and anabolic steroids in severe sarcopenia.

  14. Diagnosis and Treatment of Hypopituitarism

    Science.gov (United States)

    2015-01-01

    Hypopituitarism is a chronic endocrine illness that caused by varied etiologies. Clinical manifestations of hypopituitarism are variable, often insidious in onset and dependent on the degree and severity of hormone deficiency. However, it is associated with increased mortality and morbidity. Therefore, early diagnosis and prompt treatment is necessary. Hypopituitarism can be easily diagnosed by measuring basal pituitary and target hormone levels except growth hormone (GH) and adrenocorticotropic hormone (ACTH) deficiency. Dynamic stimulation tests are indicated in equivocal basal hormone levels and GH/ACTH deficiency. Knowledge of the use and limitations of these stimulation tests is mandatory for proper interpretation. It is necessary for physicians to inform their patients that they may require lifetime treatment. Hormone replacement therapy should be individualized according to the specific needs of each patient, taking into account possible interactions. Long-term endocrinological follow-up of hypopituitary patients is important to monitor hormonal replacement regimes and avoid under- or overtreatment. PMID:26790380

  15. Diagnosis and Treatment of Polycystic Ovary Syndrome.

    2016-07-15

    Polycystic ovary syndrome is the most common endocrinopathy among reproductive-aged women in the United States, affecting approximately 7% of female patients. Although the pathophysiology of the syndrome is complex and there is no single defect from which it is known to result, it is hypothesized that insulin resistance is a key factor. Metabolic syndrome is twice as common in patients with polycystic ovary syndrome compared with the general population, and patients with polycystic ovary syndrome are four times more likely than the general population to develop type 2 diabetes mellitus. Patient presentation is variable, ranging from asymptomatic to having multiple gynecologic, dermatologic, or metabolic manifestations. Guidelines from the Endocrine Society recommend using the Rotterdam criteria for diagnosis, which mandate the presence of two of the following three findings- hyperandrogenism, ovulatory dysfunction, and polycystic ovaries-plus the exclusion of other diagnoses that could result in hyperandrogenism or ovulatory dysfunction. It is reasonable to delay evaluation for polycystic ovary syndrome in adolescent patients until two years after menarche. For this age group, it is also recommended that all three Rotterdam criteria be met before the diagnosis is made. Patients who have marked virilization or rapid onset of symptoms require immediate evaluation for a potential androgen-secreting tumor. Treatment of polycystic ovary syndrome is individualized based on the patient's presentation and desire for pregnancy. For patients who are overweight, weight loss is recommended. Clomiphene and letrozole are first-line medications for infertility. Metformin is the first-line medication for metabolic manifestations, such as hyperglycemia. Hormonal contraceptives are first-line therapy for irregular menses and dermatologic manifestations.

    2014-02-01

    To review the pathophysiology, etiology, and treatment of attention-deficit hyperactivity disorder (ADHD). A literature search was conducted in PubMed and EMBASE using the terms attention deficit hyperactive disorder, ADHD, pathophysiology, etiology, and neurobiology. Limits applied were the following: published in the past 10 years (January 2003 to August 2013), humans, review, meta-analysis, and English language. These yielded 63 articles in PubMed and 74 in EMBASE. After removing duplicate/irrelevant articles, 86 articles and their relevant reference citations were reviewed. ADHD is a neurological disorder that affects children, but symptoms may persist into adulthood. Individuals suffering from this disorder exhibit hyperactivity, inattention, impulsivity, and problems in social interaction and academic performance. Medications used to treat ADHD such as methylphenidate, amphetamine, and atomoxetine indicate a dopamine/norepinephrine deficit as the neurochemical basis of ADHD, but the etiology is more complex. Moreover, these agents have poor adverse effect profiles and a multitude of drug interactions. Because these drugs are also dispensed to adults who may have concomitant conditions or medications, a pharmacist needs to be aware of these adverse events and drug interactions. This review, therefore, focuses on the pathophysiology, etiology, and treatment of ADHD and details the adverse effects and drug interaction profiles of the drugs used to treat it. Published research shows the benefit of drug therapy for ADHD in children, but given the poor adverse effect and drug interaction profiles, these must be dispensed with caution.

  17. Myxedema coma: diagnosis and treatment.

    Science.gov (United States)

    Wall, C R

    2000-12-01

    Myxedema coma, the extreme manifestation of hypothyroidism, is an uncommon but potentially lethal condition. Patients with hypothyroidism may exhibit a number of physiologic alterations to compensate for the lack of thyroid hormone. If these homeostatic mechanisms are overwhelmed by factors such as infection, the patient may decompensate into myxedema coma. Patients with hypothyroidism typically have a history of fatigue, weight gain, constipation and cold intolerance. Physicians should include hypothyroidism in the differential diagnosis of every patient with hyponatremia. Patients with suspected myxedema coma should be admitted to an intensive care unit for vigorous pulmonary and cardiovascular support. Most authorities recommend treatment with intravenous levothyroxine (T4) as opposed to intravenous liothyronine (T3). Hydrocortisone should be administered until coexisting adrenal insufficiency is ruled out. Family physicians are in an important position to prevent myxedema coma by maintaining a high level of suspicion for hypothyroidism.

    Pneumothorax is a serious complication of cavitary pulmonary tuberculosis. The aim of this study was to describe clinical futures, to highlight challenges of its management. A retrospective multicentric and descriptive study including 65 patients treated for PT (1999-2015) was conducted to figure out clinical futures and its work-up. The mean age was 37.8 years. The sex ratio was 3.6. Smoking history and incarceration were noted respectively in 67.6 and 15.3% of cases. Acute respiratory failure and cachexia were reported in 26.1 and 10.7% of cases. The PT was inaugural in 41.5% of cases. Pyo-pneumothorax was noted in 69.2% of cases. The duration of antituberculous treatment ranged from 6 to 15 months for susceptible TB and was at least 12 months for resistant TB (4 cases). Thoracic drainage was performed in 90.7% patients. Its average length was 47 days. The drain drop was noted in 20% of cases. Bronchopleural fistula was diagnosed in 6 cases and pleural infection in 5 of cases. Surgery treatment was necessary in 6 cases. Mean time to surgery was 171 days. Six patients had pleural decortication associated with pulmonary resection in 4 cases. Persistent chronic PT was noted in 12.6% and chronic respiratory failure in 3% of cases and death in 15.3% of cases. The diagnosis of the PT is often easy. Its treatment encounters multiples difficulties. Duration of thoracic drainage and anti-TB treatment are usually long. Surgery is proposed lately. Copyright © 2017 Elsevier Masson SAS.

    Even though laboratory tests can easily diagnose sexually transmitted diseases (STDs), they require expensive, sophisticated equipment, which is lacking in many countries, and they take several days to obtain the results. In most cases, these tests require a sample for culture or the patient must be transferred to a hospital or an STD treatment center. Often patients do not want to return for test results or for treatment or they refuse to be transferred to another health facility. Thus, the STD goes untreated. The syndromic approach addresses these obstacles to STD diagnosis and treatment at the primary health care level. Nurses, midwives, health assistants, and clinical personnel undergo training in order to be able to diagnose and treat STDs during the first visit, at a reasonable cost, and without lab tests. They identify principal groups of signs and symptoms (i.e., syndromes) common to certain STDs. Prescribed drugs must be effective, cause no side effects, be available at the same center as the first consultation, and, preferably, be administered orally or by one dose. STD control programs need to identify the most prevalent syndromes and etiologic agents in the area and determine the most effective antibiotics for those syndromes. Donovanosis, syphilis, and soft chancre are responsible for genital ulcers in India and in Papua New Guinea; only syphilis and soft chancre are in other areas. Thus, it is important to provide treatment for all three causes in India and Papua New Guinea. It is easier to diagnose and treat penal discharge and genital ulcers in men and women than vaginal discharge and/or symptoms of pelvic inflammation in women. Thus, health workers need to ask a series of questions on risk factors for gonorrhea and chlamydia.

    The sensitivity in the diagnosis of cerebrovascular diseases using radiotracers can be enhanced by the use of the acetazolamide test. In this paper we present and discuss some physiological and pathophysiological aspects of its mechanism. The physiological action of the carboanhydrase inhibitor is like the action of enhanced pCO{sub 2} in the tissue, thus acting at the site of metabolic regulation. The reaction of the vascular bed is influenced in part by subcortical structures. Pathologically the reaction can be disturbed at first by an altered regulation with the vessels being mechanically intact, e.g. in hypoxia or transient ischemia. Secondly, the mechanics of the vessels may be not intact e.g., in atherosclerosis or surrounding edema. Lastly, the vessels have already dilated, e.g. poststenotically. All these facts have to be taken into consideration interpreting an acetazolamid test. (orig.).

    Primary headaches are one of the most common disorders of childhood, with migraine and tension type headaches (TTHs) being the most frequent ones. In spite of their prevalence, there is paucity of knowledge regarding the underlying pathophysiological mechanisms that cause headaches and regarding the unique aspects of headaches in children and adolescents. To review the literature and summarize the knowledge regarding clinical features, diagnosis and management of primary headache in children and adolescents, mainly migraine and TTH. Most of our current knowledge regarding primary headaches in children and adolescents is driven from extrapolations from studies that were conducted with adult patients. Therefore, it needs to be validated for the different age groups. Migraines may be diagnosed effectively based on the 2nd edition of the International Classification of Headache Disorders (ICHD-II), however, TTH is diagnosed mainly by the absence of features found in other headache types. Treatment strategies for primary headaches vary according to patient's age, family structure, culture and beliefs, headache diagnosis, and based on the disability the headache imposes on the patient's daily living. It was shown that a multidisciplinary approach, that includes continuing counseling, education, and reassurance, in combination with pharmacological and non-pharmacological treatment, is an effective strategy for children and adolescents suffering from primary headaches. Further studies are needed to enrich our knowledge about the pathophysiological mechanisms that cause headaches in children and adolescents and to develop efficient strategies to alleviate their burden.

Sildenafil and tadalafil may induce reversible increase in intraocular pressure and be involved in the development of nonarteritic ischemic optic neuropathy. Reversible idiopathic serous macular detachment, central serous chorioretinopathy, and ERG disturbances have been related to the significant impact of sildenafil and tadalafil on retinal perfusion.Discussion: So far, PDE inhibitors do not seem to cause permanent toxic effects on chorioretinal tissue and photoreceptors. However, physicians should write down any visual symptom observed during PDE treatment and refer the patients to ophthalmologists.

    2017-04-01

    Full Text Available Chronic thromboembolic pulmonary hypertension (CTEPH is currently underdiagnosis and consequently undertreatment in the clinical practice. A deficient in diagnostic modality and treatment availability especially in developing countries makes the CTEPH diagnosis unlikely to confirm. However, high index of clinical suspicion of CTEPH will lead to proper diagnosis and correct treatment  with significant reduction in morbidity and mortality. Left untreated, the mean survival time is 6.8 years and the three year mortality rate may be as high as 90 %. The pathophysiology, diagnosis and treatment of CTEPH are necessary to be shared among internists and primary care physicians, in order to improve the overall outcome of the patients.

    Full Text Available With the progress in research on portal hypertension in recent years, portal hypertensive biliopathy (PHB has attracted more and more attention. The pathophysiology and clinical manifestations of PHB, as well as the main methods for the diagnosis and treatment of this disease, are briefly described. The pathogenesis of PHB remains unclear, and it has been postulated that the external pressure of portal cavernoma and the ischemic stricture of the bile duct may play a role. Magnetic resonance cholangiopancreatography is the primary diagnostic tool for PHB. Currently, it is thought that asymptomatic PHB patients do not require any treatment, and symptomatic PHB patients should receive individualized treatment, which mainly included reducing portal pressure and relieving biliary obstruction. Transjugular intrahepatic portosystemic shunt has become the first-line therapy for symptomatic PHB. More research and practice are needed for further understanding of PHB.

    2010-12-01

    Chronic pruritus is a major and distressing symptom of many cutaneous and systemic diseases and can significantly impair the patient's quality of life. Pruritus perception is the final result of a complex network involving dedicated nerve pathways and brain areas, and an increasing number of peripheral and central mediators are thought to be involved. Itch is associated with most cutaneous disorders and, in these circumstances, its management overlaps with that of the skin disease. Itch can also occur without associated skin diseases or primary skin lesions, but only with nonspecific lesions secondary to rubbing or scratching. Chronic itch with no or minimal skin changes can be secondary to important diseases, such as neurologic disorders, chronic renal failure, cholestasis, systemic infections, malignancies, and endocrine disorders, and may also result from exposure to some drugs. The search for the cause of pruritus usually requires a meticulous step-by-step assessment involving careful history taking as well as clinical examination and laboratory investigations. Few evidence-based treatments for pruritus are available. Topical therapy, oral histamine H(1) receptor antagonists, and phototherapy with UV radiation can target pruritus elicitation in the skin, whereas antiepileptic drugs, opioid receptor antagonists, and antidepressants can block signal processing in the CNS.

    2018-02-01

    Full Text Available Tumor necrosis factor-stimulated gene-6 (TSG-6 is a 35-kDa glycoprotein that has been shown to exert anti-inflammatory effects in experimental models of arthritis, acute myocardial infarction, and acute cerebral infarction. Several lines of evidence have shed light on the pathophysiological roles of TSG-6 in atherosclerosis. TSG-6 suppresses inflammatory responses of endothelial cells, neutrophils, and macrophages as well as macrophage foam cell formation and vascular smooth muscle cell (VSMC migration and proliferation. Exogenous TSG-6 infusion and endogenous TSG-6 attenuation with a neutralizing antibody for four weeks retards and accelerates, respectively, the development of aortic atherosclerotic lesions in ApoE-deficient mice. TSG-6 also decreases the macrophage/VSMC ratio (a marker of plaque instability and promotes collagen fibers in atheromatous plaques. In patients with coronary artery disease (CAD, plasma TSG-6 levels are increased and TSG-6 is abundantly expressed in the fibrous cap within coronary atheromatous plaques, indicating that TSG-6 increases to counteract the progression of atherosclerosis and stabilize the plaque. These findings indicate that endogenous TSG-6 enhancement and exogenous TSG-6 replacement treatments are expected to emerge as new lines of therapy against atherosclerosis and related CAD. Therefore, this review provides support for the clinical utility of TSG-6 in the diagnosis and treatment of atherosclerotic cardiovascular diseases.

    2017-02-01

    Full Text Available Ampullary tumors mainly manifest as obstructive jaundice and ampullary mass in clinical practice and are difficult to be identified in early stage due to a complex structure of the anatomical site, a deep location, and hidden symptoms. Sometimes a qualitative diagnosis cannot be made. Based on the experience in the treatment of ampullary tumors for many years in our center, this article summarizes the features of ampullary tumors from the aspects of clinical manifestations, diagnosis, treatment, and prognosis, especially the issues regarding imaging evaluation of ampullary tumors, selection of surgical procedure, and prognosis. An early diagnosis is the key to the treatment of ampullary tumors, and early identification and treatment of lesions have great impacts on patients′ prognosis. Accurate preoperative imaging evaluation, a professional diagnosis and treatment team, accurate preoperative and intraoperative pathological analysis, and implementation of reasonable therapeutic strategy are the key to patients′ recovery.

  15. A Proteomic Approach for the Diagnosis of ‘Oketsu’ (blood stasis, a Pathophysiologic Concept of Japanese Traditional (Kampo Medicine

    2008-01-01

    Full Text Available ‘Oketsu’ is a pathophysiologic concept in Japanese traditional (Kampo medicine, primarily denoting blood stasis/stagnant syndrome. Here we have explored plasma protein biomarkers and/or diagnostic algorithms for ‘Oketsu’. Sixteen rheumatoid arthritis (RA patients were treated with keishibukuryogan (KBG, a representative Kampo medicine for improving ‘Oketsu’. Plasma samples were diagnosed as either having an ‘Oketsu’ (n = 19 or ‘non-Oketsu’ (n = 29 state according to Terasawa's ‘Oketsu’ scoring system. Protein profiles were obtained by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS and hierarchical clustering and decision tree analyses were performed. KBG treatment for 4 or 12 weeks decreased the ‘Oketsu’ scores significantly. SELDI protein profiles gave 266 protein peaks, whose expression was significantly different between the ‘Oketsu’ and ‘non-Oketsu’ states. Hierarchical clustering gave three major clusters (I, II, III. The majority (68.4% of ‘Oketsu’ samples were clustered into one cluster as the principal component of cluster I. The remaining ‘Oketsu’ profiles constituted a minor component of cluster II and were all derived from patients cured of the ‘Oketsu’ state at 12 weeks. Construction of the decision tree addressed the possibility of developing a diagnostic algorithm for ‘Oketsu’. A reduction in measurement/pre-processing conditions (from 55 to 16 gave a similar outcome in the clustering and decision tree analyses. The present study suggests that the pathophysiologic concept of Kampo medicine ‘Oketsu’ has a physical basis in terms of the profile of blood proteins. It may be possible to establish a set of objective criteria for diagnosing ‘Oketsu’ using a combination of proteomic and bioinformatics-based classification methods.

    2016-01-01

    Gastrointestinal (GI) side-effects of chemotherapy are a debilitating and often overlooked clinical hurdle in cancer management. Chemotherapy-induced constipation (CIC) and Diarrhea (CID) present a constant challenge in the efficient and tolerable treatment of cancer and are amongst the primary contributors to dose reductions, delays and cessation of treatment. Although prevalence of CIC is hard to estimate, it is believed to affect approximately 16% of cancer patients, whilst incidence of CID has been estimated to be as high as 80%. Despite this, the underlying mechanisms of both CID and CIC remain unclear, but are believed to result from a combination of intersecting mechanisms including inflammation, secretory dysfunctions, GI dysmotility and alterations in GI innervation. Current treatments for CIC and CID aim to reduce the severity of symptoms rather than combating the pathophysiological mechanisms of dysfunction, and often result in worsening of already chronic GI symptoms or trigger the onset of a plethora of other side-effects including respiratory depression, uneven heartbeat, seizures, and neurotoxicity. Emerging treatments including those targeting the enteric nervous system present promising avenues to alleviate CID and CIC. Identification of potential targets for novel therapies to alleviate chemotherapy-induced toxicity is essential to improve clinical outcomes and quality of life amongst cancer sufferers.

    2017-12-01

    Full Text Available For the diagnosis of reflex syncope, diligent history-building with the patient and a witness is required. In the Emergency Department (ED, the assessment of syncope is a challenge which may be addressed by an ED Observation Unit or by a referral to a Syncope Unit. Hospital admission is necessary for those with life-threatening cardiac conditions although risk stratification remains an unsolved problem. Other patients may be investigated with less urgency by carotid sinus massage (>40 years, tilt testing, and electrocardiogram loop recorder insertion resulting in a clear cause for syncope. Management includes, in general terms, patient education, avoidance of circumstances in which syncope is likely, increase in fluid and salt consumption, and physical counter-pressure maneuvers. In older patients, those that will benefit from cardiac pacing are now well defined. In all patients, the benefit of drug therapy is often disappointing and there remains no ideal drug. A role for catheter ablation may emerge for the highly symptomatic reflex syncope patient. Keywords: Cardiac pacing, Catheter ablation, Diagnosis, Drugs, Management, Reflex syncope

    Endometriosis is a common condition in women of reproductive age. In addition to pain, endometriosis may also reduce fertility. The causes of infertility in women with endometriosis may range from anatomical distortions due to adhesions and fibrosis to endocrine abnormalities and immunological disturbances. In some cases, the various pathophysiological disturbances seem to interact through mechanisms so far not fully understood. Whether surgery should be offered as a treatment option in endometriosis-associated infertility has become controversial, partly due to its modest or undocumented effect. Medical or hormonal treatment alone has little or no effect and should only be used in conjunction with assisted reproductive technology (ART). Of the various methods of ART, intrauterine insemination, due to its simplicity, can be recommended in women with minimal or mild peritoneal endometriosis, even though insemination may yield a lower success rate than in women without endometriosis. In vitro fertilization (IVF) is an effective treatment option in less-advanced disease stages, and the success rates are similar to the results in other causes of infertility. However, women with more advanced stages of endometriosis have lower success rates with IVF. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

    Multiple myeloma, the most common bone malignancy, is occurring with increasing frequency in older persons. Typical symptoms are bone pain, malaise, anemia, renal insufficiency, and hypercalcemia. Incidental discovery on comprehensive laboratory panels is common. The disease is diagnosed with serum or urine protein electrophoresis or immunofixation and bone marrow aspirate analysis. Skeletal radiographs are important in staging multiple myeloma and revealing lytic lesions, vertebral compression fractures, and osteoporosis. Magnetic resonance imaging and positron emission tomography or computed tomography are emerging as useful tools in the evaluation of patients with myeloma; magnetic resonance imaging is preferred for evaluating acute spinal compression. Nuclear bone scans and dual energy x-ray absorptiometry have no role in the diagnosis and staging of myeloma. The differential diagnosis of monoclonal gammopathies includes monoclonal gammopathy of uncertain significance, smoldering (asymptomatic) and symptomatic multiple myeloma, amyloidosis, B-cell non-Hodgkin lymphoma, Waldenström macroglobulinemia, and rare plasma cell leukemia and heavy chain diseases. Patients with monoclonal gammopathy of uncertain significance or smoldering multiple myeloma should be followed closely, but not treated. Symptomatic multiple myeloma is treated with chemotherapy followed by autologous stem cell transplantation, if possible. Melphalan, prednisolone, dexamethasone, vincristine, doxorubicin, bortezomib, and thalidomide and its analogue lenalidomide have been used successfully. It is important that family physicians recognize and appropriately treat multiple myeloma complications. Bone pain is treated with opiates, bisphosphonates, radiotherapy, vertebroplasty, or kyphoplasty; nephrotoxic nonsteroidal anti-inflammatory drugs should be avoided. Hypercalcemia is treated with isotonic saline infusions, steroids, furosemide, or bisphosphonates. Because of susceptibility to infections

    Stress urinary incontinence (SUI) is the most common type of urinary incontinence (UI) in pregnant women and is known to have detrimental effects on the quality of life in approximately 54.3 %. Pregnancy is the main risk factor for the development of SUI. This review provides details of the pathophysiology leading to SUI in pregnant women and SUI prevalence and treatment during pregnancy. We conducted a PubMed search for English-language and human-study articles registered from January 1990 to September 2012. This search was performed for articles dealing with prevalence and treatment of SUI during pregnancy. In the intervention studies, we included studies that used a randomized controlled trial (RCT) design or studies comparing a treatment intervention to no treatment. A total of 534 articles were identified; 174 full-text articles were reviewed, and 28 of them met eligibility criteria and are reported on here. The mean prevalence of SUI during pregnancy was 41 % (18.6-60 %) and increased with gestational age. The increasing pressure of the growing uterus and fetal weight on pelvic-floor muscles (PFM) throughout pregnancy, together with pregnancy-related hormonal changes, may lead to reduced PFM strength as well as their supportive and sphincteric function. These cause mobility of the bladder neck and urethra, leading to urethral sphincter incompetence. Pelvic floor muscle exercise (PFME) is a safe and effective treatment for SUI during pregnancy, without significant adverse effects. Understanding these issues can be useful for health-care professionals when informing and counseling pregnant women to help prevent SUI during pregnancy and the postpartum period.

    The localized intraabdominal bile collection or biloma has recently been diagnosed in increased frequently due to the wide spread use of US, CT, DISIDA scintigram, and radiologically guided percutaneous needle aspiration with or without subsequent catheter drainage. The underlying cause of biloma is trauma or iatrogenic injury which includes abdominal surgery, percutaneous drainage or PTC. We experience 20 patients with 22 biloma diagnostically confirmed by DISIDA scan, image-guided needle aspiration, percutaneous catheter drainage and / or operation. Of the 22 biloma, 7 were intrahepatic and 15 were extrahepatic. Of the 15 extrahepatic biloma, 7 were in partially hepatectomized bed, 3 were subhepatic, 3 were right subphrenic and 1 was subcapsular. We were able to determine the infectivity in 16 biloma and of these 12 biloma were found to be infected. Percutaneous drainage was performed on 20 biloma in 18 patients : by a needle aspiration with irrigation on 2 patient and by percutaneous catheter drainage on 18 bilomas. Overall success rate of the drainage was 90%. Cause of the two failures were CHD stone with choledochoduodenal fistula and recurrent hemobilia with acute cholecystitis. We describe the processes in reaching the diagnosis of biloma, propensity of biloma to purulent intrahepatic or perihepatic abscess formation, and the necessity of percutaneous radiologic catheter drainage as an optional management

    Recent years have seen an increasing number of car occupants with neck complaints following a car collision and a declining number of persons involved in car crashes--a relationship that is not well understood. Presumably less than 5% will suffer from persistent, (long-lasting), disabling neck pain. Although mostly men are involved in motor vehicle accidents, an equal number of men and women seek emergency care, but it is mostly women, who have persistent (long-lasting) neck complaints after a car collision. In general, there is no documentation of specific injury to the brain or spinal cord from a simple whiplash (WAD 1-3). Whiplash-related neck pain is caused by a distortion of the cervical spine, and, as such, should be interpreted as a benign condition with a good prognosis. Whiplash should be considered a risk factor rather than a medical diagnosis. The association between cause (whiplash mechanism) and effect (symptoms) is poor. Persistent (long-lasting) health problems from a whiplash should be treated like other post-traumatic conditions, and need a bio-psycho-social approach.

    2016-07-01

    Patients who continue to experience heartburn symptoms despite adequate-dose proton pump inhibitor therapy have unmet clinical needs. In this review, we focus on the most recent findings related to the mechanism of heartburn symptom generation, and on the treatment of gastroesophageal reflux disease-related and functional heartburn. The immunological mechanism in the esophageal mucosa has been addressed as a potential mechanism of the onset of esophageal mucosa damage and the generation of heartburn symptoms. Peripheral or central hypersensitivity in viscera is a potentially unifying pathophysiological concept in functional heartburn. Vonoprazan, a novel and potent first-in-class potassium-competitive acid blocker, is expected to prove useful in the treatment of reflux disease. New findings in the mechanisms of heartburn symptom generation are emerging, including the immunological mediation of esophageal mucosal damage and the development of visceral hypersensitivity in functional heartburn. In the future, we anticipate the emergence of new and specific therapeutic options based on these mechanisms, with less dependence on acid-suppressing agents.

    Oropharyngeal dysphagia (OD) affects older and neurological patients, causing malnutrition and dehydration and increasing the risk for aspiration pneumonia. There is evidence that sensory deficits in those populations are closely related to swallowing disorders, and several research groups are developing new therapies based on sensory stimulation of this area. More information on the sensory innervation participating in the swallow response is needed to better understand the pathophysiology of OD and to develop new treatments. This review focuses on the sensory innervation of the human oropharynx and larynx in healthy people compared with patients with swallowing disorders in order to unravel the abnormalities that may lead to the loss of sensitivity in patients with OD. We also hypothesize the pathway through which active sensory-enhancement treatments may elicit their therapeutic effect on patients with swallowing dysfunctions. As far as we know, this is the first time a review covers the anatomy, histology, ultrastructure, and molecular biology of the sensory innervation of the swallowing function. © 2016 New York Academy of Sciences.

    1991-01-01

    Sigmoid volvolus is an emergency which requires rapid diagnosis and immediate adequate treatment. Diagnosis is primarily radiological. Emergency laparotomy carries a high mortality and should therefore not be the immediate treatment. In our opinion, detorsion by colonoscopy under radiological control is a promising form of treatment. Selective resection of the sigmoid, thereby removing the cause of the abnormality, should not be forgotten, since this prevents recurrences. For this method, mortality after adequate gut preparation is only 5.4%. An exception to the above is gangrene of the bowel, when an emergency laparotomy cannot be avoided. (orig.) [de

    Treatment of small but painful osteoid osteomas was traditionally based on either prolonged medication or resection. In the era of rapidly evolving minimally invasive techniques, reluctance has been posed against surgical interventions mostly due to their relatively high rates of recurrence, complications, or persistent pain. Nonetheless, incomplete pain control and intolerance to anti-inflammatory drugs unfavorably affect prognosis. The objective of this article is to explore the nature and clinical presentation of osteoid osteomas, discuss their imaging and histological features, review available data regarding surgical and percutaneous methods for addressing these lesions and comment on their feasibility, safety, and efficacy.

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE Undescended testis (UDT or cryptorchidism is one of the commonest abnormalities in male infants. In this anomaly, testes are not located normally in the scrotum. The incidence of UDT is 4-5% of term male infants, and 20-33% of premature male infants. The occurrence of abnormalities of hormones control or anatomy process that is required in the normal process of lowering the testes can cause UDT. UDT can be differentiated into palpable and nonpalpable. The diagnosis of UDT can be known through physical examination. However, if the testes are impalpable, laparoscopy can be done to determine the position of the testis. Hormonal therapy to overcome UDT is still under controversy. The action that often done is surgery, called orchidopexy. The most serious complication of orchidopexy is testicular atrophy. It occurs in a small percentage, which is about 5-10%. Infertility may occur in 1 to 3 of 4 adult males and the risk of occurrence of malignancies is increased by as much as 5-10 times higher in men with a history of UDT. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

    To review the most relevant publications on the pathophysiology, clinical manifestations, diagnosis and treatment of esophageal achalasia, and the clinical experience achieved at our institution in order to propose a practical strategy to facilitate the management of these patients. Manual and MEDLINE search of key articles published between January 1986 and July 1997 in addition to publications of our institute of thirty years. All kinds of publications with substantial clinical experience, new information or research protocols. Achalasia is an uncommon disorder of the myenteric plexus of the esophagus. Main symptoms are dysphagia, regurgitations and chest pain. The diagnosis is established by manometric criteria. Esophagogram, endoscopy and radionuclide esophageal emptying test help to differentiate other conditions and evaluate the response to treatment. Pharmacotherapy may provide relief to patients with mild symptoms and is useful for patients with high risk of complications. Dilations and myotomy are safe, effective and long lasting procedures. Botulinum toxin may be effective in selected cases. Predictive factors of response have been described for each therapy. A systematic approach to the management of patients with achalasia is necessary. Introduction of new therapies as botulinum toxin and minimal invasion surgery are changing the therapeutic decisions in this field. Drugs and BoTox are considered the first line of treatment for high risk patients and dilation and surgery for patients with no risk.

    2001-01-01

    Kleptomania--the inability to resist the impulse to steal objects, not for personal use or monetary gain--is currently classified in psychiatric nomenclature as an impulse control disorder. However, some of the principle features of the disorder, which include repetitive intrusion thoughts, inability to resist the compulsion to perform the thievery and the relief of tension following the act, suggest that kleptomania may constitute an obsessive-compulsive spectrum disorder. Kleptomania is commonly under-diagnosed and is often accompanied by other psychiatric conditions, most notably affective, anxiety and eating disorders, and alcohol and substance abuse. Individuals with the disorder are usually referred for treatment due to the comorbid psychiatric complaints rather than kleptomanic behaviour per se. Over the past century there has been a shift from psychotherapeutic to psychopharmacological interventions for kleptomania. Pharmacological management using selective serotonin (5-hydroxytryptamine; 5-HT) reuptake inhibitors (SSRIs) and other antidepressants, mood stabilisers and opioid receptor antagonists, as adjuvants to cognitive-behavioural therapy, has produced promising results.

    2018-01-01

    Full Text Available Due to the development of synovitis, early-stage hand osteoarthritis (HOA mimics hand joint injury in rheumatoid arthritis (RA. However, the topography of synovitis is diverse in these diseases:  distal interphalangeal and thumb joints are involved in the process in HOA. In the latter, tests are negative for immunological markers  (anti-cyclic citrullinated peptide antibodies, which is typical of RA.  The differences between HOA and RA are prominent, as evidenced  by hand X-rays and magnetic resonance imaging. Investigations  suggest that cytokine profile imbalance is implicated in the  pathogenesis of osteoarthritis, which brings it closer to RA. However, therapy for HOA has not been practically developed; there are only a few works on the use of disease-modifying antirheumatic drugs and  biological agents in these patients. It is necessary to work out Russian guidelines for the treatment of HOA.

  1. Nummular headache: diagnosis and treatment.

    Pareja, Juan A; Pareja, Julia

    2003-05-01

    Nummular headache (coin-shaped cephalgia) has an unusual distinct feature: it is characterized by mild-to-moderate pressure-like pain exclusively felt in a rounded or elliptical area typically 2-6 cm in diameter. Although any region of the head may be affected, the parietal area is the common localization of nummular headache. The pain remains confined to the same symptomatic area which does not change in shape or size with time. The pain is continuous but lancinating exacerbations lasting for several seconds or gradually increasing from 10 mins to 2 h may superimpose the baseline pain. The temporal pattern is either chronic or remitting. Pseudoremissions may be observed when the pain reaches a very low grade or only discomfort (not pain) in the affected area is reported. At times, discomfort may prevail. Either during symptomatic periods or interictally, the affected area may show a variable combination of hypoethesia, dysesthesia, paresthesia or tenderness. Physical and supplementary examinations are normal. Nummular headache emerges as a primary clear-cut clinical picture. The particular topography and signs of sensory dysfunction make it reasonable to vent the idea that nummular headache is an extracranial headache, probably stemming from epicranial tissues such as terminal branches of sensitive nerves. Nummular headache may seem to be the paradigm of epicranias (group of headaches and pericranial neuralgias stemming from epicranial tissues). Nummular headache must be distinguished from head pain secondary to local processes and from tender points of more extensive headaches. Although nummular headache may frequently coexist with other primary headaches, it has an independent course. Treatment is seldom necessary and in most cases simple reassurance is sufficient.

    2013-01-11

    Breast cancer is the most common female cancer and globally remains a major public health concern. The diagnosis and treatment of breast cancer continues to develop. Diagnosis is now more precise, surgery is less mutilating and women now have the option of breast conserving therapy with better cosmesis, and without sacrificing survival. Radiotherapy is more targeted and the selection of patients for adjuvant chemotherapy is based not only on prognostic and predictive factors, but also on newer molecular profiling that will ensure that chemotherapy is given to the patients who need and respond to it. These developments all provide a more tailored approach to the treatment of breast cancer. Management now involves a multidisciplinary team approach in order to provide the highest standard of care for patients throughout their cancer journey from diagnosis through treatment and into follow-up care.

    Full Text Available Diabetes insipidus represents a serious disease that dramatically interferes with the everyday life of patients due to the need to constantly replenish of fluid lost in the urine, which comes amid shortage of synthesis, secretion or action of pituitary hormone vasopressin. The main difficulty is the differential diagnosis of types of diabetes insipidus in patients with the syndrome of polydipsia-polyuria as the correct differential diagnosis of these forms predetermine the safety and efficacy of further treatment. This lecture presents the current concepts of etiology, diagnosis and treatment of central diabetes insipidus (CDI. We give the comparative characteristics of various preparations of desmopressin for the treatment of the central form of the disease. We also consider the features of the management of selected patient populations with CDI: during pregnancy and lactation, pathology of the thirst sensation, after traumatic brain injury and neurosurgery.

    Children with dyscalculia show deficits in basic numerical processing which cause difficulties in the acquisition of mathematical skills. This article provides an overview of current research findings regarding the symptoms, cause, and prognosis of dyscalculia, and it summarizes recent developments in the diagnosis, early intervention, and treatment thereof. Diagnosis has improved recently because newly developed tests focus not only on the math curriculum, but also on basic skills found to be impaired in dyscalculia. A controversial debate continues with regard to IQ achievement discrepancy. International studies have demonstrated the effectiveness of specialized interventions. This article summarizes the research findings from intervention studies, describes different treatment approaches, and discusses implications for clinical practice.

  6. Pathophysiology and diagnosis of hibernating myocardium in patients with post-ischemic heart failure. The contribution of PET

    Camici, P.G.; Rimoldi, O.E.

    2003-01-01

    Identification and treatment of hibernating myocardium (HM) lead to improvement in left ventricular (LV) function and prognosis in patients with post-ischemic heart failure. Different techniques are used to diagnose HM: echocardiography, MRI, SPECT and PET and, in patients with moderate LV impairment, their predictive values are similar. There are few data on patients with severe LV dysfunction and heart failure in whom the greatest benefits are apparent after revascularization. Quantification of FDG uptake with PET during hyperinsulinemic euglycemic clamp is accurate in these patients with the greatest mortality risk in whom other techniques may give high false negative rates. The debate on whether resting myocardial blood flow to HM is reduced or not has stimulated new research on heart failure in patients with coronary artery disease. PET with H 2 15 O or 13 NH 3 has been used for the absolute quantification of regional blood flow in human HM. When HM is properly identified, resting blood flow is not different from that in healthy volunteers although a reduction of ∼20% can be demonstrated in a minority of cases. PET studies have shown that the main feature of HM is a severe impairment of coronary vasodilator reserve that improves after revascularization in parallel with LV function. Thus, the pathophysiology of HM is more complex than initially postulated. The recent evidence that repetitive ischemia in patients can be cumulative and lead to more severe and prolonged stunning, lends further support to the hypothesis that, at least initially, stunning and HM are two facets of the same coin.

    2012-07-01

    Upper limb apraxia, a disorder of higher motor cognition, is a common consequence of left-hemispheric stroke. Contrary to common assumption, apraxic deficits not only manifest themselves during clinical testing but also have delirious effects on the patients' everyday life and rehabilitation. Thus, a reliable diagnosis and efficient treatment of upper limb apraxia is important to improve the patients' prognosis after stroke. Nevertheless, to date, upper limb apraxia is still an underdiagnosed and ill-treated entity. Based on a systematic literature search, this review summarizes the current tools of diagnosis and treatment strategies for upper limb apraxia. It furthermore provides clinicians with graded recommendations. In particular, a short screening test for apraxia, and a more comprehensive diagnostic apraxia test for clinical use are recommended. Although currently only a few randomized controlled studies investigate the efficacy of different apraxia treatments, the gesture training suggested by Smania and colleagues can be recommended for the therapy of apraxia, the effects of which were shown to extend to activities of daily living and to persist for at least 2 months after completion of the training. This review aims at directing the reader's attention to the ecological relevance of apraxia. Moreover, it provides clinicians with appropriate tools for the reliable diagnosis and effective treatment of apraxia. Nevertheless, this review also highlights the need for further research into how to improve diagnosis of apraxia based on neuropsychological models and to develop new therapeutic strategies.

    Urinary tract infection (UTI) is the most common serious bacterial infection in childhood. Prompt diagnosis and treatment are required for the optimal clinical outcome and the prevention of long-term morbidity and sequelae. Diagnosis and treatment of UTI may seem to be easy tasks, but they remain among the most controversial issues in pediatrics. Consequently, children suspected for UTIs are investigated and treated differently in different settings. The absence of typical clinical presentation and the uncertainties in setting the index of suspicion, collecting appropriate urine samples and interpreting results, combined with different antibiotic policies in the face of increasing resistance of uropathogens, contribute to the controversy. Recently issued guidelines have attempted to settle several thorny aspects in diagnosis and treatment, but quite a few issues still remain controversial. In this review, the authors explore the current situation on diagnosis and treatment of childhood UTI in better understanding their pathogenesis and prevalence in different child populations, discuss recently evaluated diagnostic tests and the new management guidelines.

    2016-05-01

    This paper provides an overview of cognitive impairment due to vascular brain damage, which is referred to as vascular cognitive impairment (VCI). Over the past decades, we have seen marked progress in detecting VCI, both through maturation of diagnostic concepts and through advances in brain imaging, especially MRI. Yet in daily practice, it is often challenging to establish the diagnosis, particularly in patients where there is no evident temporal relation between a cerebrovascular event and cognitive dysfunction. Because vascular damage is such a common cause of cognitive dysfunction, it provides an obvious target for treatment. In patients whose cognitive dysfunction follows directly after a stroke, the etiological classification of this stroke will direct treatment. In many patients however, VCI develops due to so-called "silent vascular damage," without evident cerebrovascular events. In these patients, small vessel diseases (SVDs) are the most common cause. Yet no SVD-specific treatments currently exist, which is due to incomplete understanding of the pathophysiology. This review addresses developments in this field. It offers a framework to translate diagnostic criteria to daily practice, addresses treatment, and highlights some future perspectives.

In conjunction with the serological reactions to echinococcosis they allow in most cases the diagnosis of the disease. However, false-negative results of serological tests in more than 10–20 % of the patients and the difficulty of differential diagnosis with small brush size and "pseudotumoral" forms of ultrasound often lead to delayed diagnosis, and thus to a deterioration of treatment results. Moreover, failure to identify at an early stage of echinococcosis virtually eliminates the possibility of conservative treatment of echinococcosis without performing surgery.It is given the profound immune disorders in patients with echinococcosis, treatment should be complex and along with the surgical removal of hydatid cyst should be included in it and biostimulating.

    Fibromyalgia syndrome is mainly characterized by pain, fatigue, and sleep disruption. The etiology of fibromyalgia is still unclear: if central sensitization is considered to be the main mechanism involved, then many other factors, genetic, immunological, and hormonal, may play an important role. The diagnosis is typically clinical (there are no laboratory abnormalities) and the physician must concentrate on pain and on its features. Additional symptoms (e.g., Raynaud's phenomenon, irritable bowel disease, and heat and cold intolerance) can be associated with this condition. A careful differential diagnosis is mandatory: fibromyalgia is not a diagnosis of exclusion. Since 1990, diagnosis has been principally based on the two major diagnostic criteria defined by the ACR. Recently, new criteria have been proposed. The main goals of the treatment are to alleviate pain, increase restorative sleep, and improve physical function. A multidisciplinary approach is optimal. While most nonsteroidal anti-inflammatory drugs and opioids have limited benefit, an important role is played by antidepressants and neuromodulating antiepileptics: currently duloxetine (NNT for a 30% pain reduction 7.2), milnacipran (NNT 19), and pregabalin (NNT 8.6) are the only drugs approved by the US Food and Drug Administration for the treatment of fibromyalgia. In addition, nonpharmacological treatments should be associated with drug therapy. PMID:23213512

    Wolfram syndrome is a rare genetic disorder characterized by juvenile-onset diabetes mellitus, diabetes insipidus, optic nerve atrophy, hearing loss, and neurodegeneration. Although there are currently no effective treatments that can delay or reverse the progression of Wolfram syndrome, the use of careful clinical monitoring and supportive care can help relieve the suffering of patients and improve their quality of life. The prognosis of this syndrome is currently poor, and many patients die prematurely with severe neurological disabilities, raising the urgency for developing novel treatments for Wolfram syndrome. In this article, we describe natural history and etiology, provide recommendations for diagnosis and clinical management, and introduce new treatments for Wolfram syndrome.

    Myxedema coma is defined as severe hypothyroidism leading to decreased mental status, hypothermia, and other symptoms related to dysfunction in multiple organs. It is very rare disease with high mortality rate. Early recognition and therapy of myxedema coma are essential, and treatment should be begun on the basis of clinical suspection. However, regimen of myxedema is not well established even now, especially about thyroid hormone supplementation. Japan Thyroid Association is drawing up "The diagnostic criteria of myxedema coma (3rd draft) and preliminary guide to treatment of it". According to this criteria and preliminary guide, the clinical presentation, diagnosis, and treatment of myxedema coma will be reviewed here.

    Full Text Available Recent studies on the clinical importance of tuberculin skin tests (TST, interferon-gamma release assays (IGRAs, chest computed tomography (CT and polymerase chain reaction have provided a new approach to diagnosing ocular tuberculosis (TBC. However, both TST and IGRAs cannot distinguish between latent TBC infection and active disease. Another corroborative test in the diagnosis of intraocular TBC is the evaluation of the lungs by either chest radiography or CT. Direct evidence for the diagnosis can be obtained by examination of smears and staining for acid-fast organisms, cultures of intraocular tissue/fluid for Mycobacterium tuberculosis, and nucleic acid amplification analysis. In recent years, guidelines have been suggested for the diagnosis of intraocular TBC. The current treatment of intraocular TBC consists of use of four drugs (isoniazid, rifampicin, ethambutol and pyrazinamide taken for a long period of time (total 9-15 months.

    Pneumothorax is an urgent situation that has to be treated immediately upon diagnosis. Pneumothorax is divided to primary and secondary. A primary pneumothorax is considered the one that occurs without an apparent cause and in the absence of significant lung disease. On the other hand secondary pneumothorax occurs in the presence of existing lung pathology. There is the case where an amount of air in the chest increases markedly and a one-way valve is formed leading to a tension pneumothorax. Unless reversed by effective treatment, this situation can progress and cause death. Pneumothorax can be caused by physical trauma to the chest or as a complication of medical or surgical intervention (biopsy). Symptoms typically include chest pain and shortness of breath. Diagnosis of a pneumothorax requires a chest X-ray or computed tomography (CT) scan. Small spontaneous pneumothoraces typically resolve without treatment and require only monitoring. In our current special issue we will present the definition, diagnosis and treatment of pneumothorax from different experts in the field, different countries and present different methods of treatment.

    This paper explains the outline of the present diagnosis and treatment of breast cancer essentially based on its therapeutic guideline by the Japan Breast Cancer Society (2005) and on authors' experiences. The diagnosis item contains the medical interview of patients, observatory and palpating examinations, mammography (for this, Japan-Breast Imaging Recording and Data System), ultrasonography (guideline for sonographic diagnosis of mammary gland, 2004), fine needle aspiration (FNA) or aspiration biopsy cytology, bases of triple test (palpation, mammography and FNA) for the cancer diagnosis, core needle biopsy, and mammotome biopsy of non-palpable calcified lesion. The treatment item contains the surgery involving conservation, sentinel lymph node biopsy (for this, lymphoscintigraphy with Tc-phytate is illustrated), radiofrequency ablation, adjuvant chemotherapy essentially using anthracycline and taxane, endocrinological therapy using tamoxifen, LH-RH analogues and aromatase inhibitors, and molecular target therapy with HER2 monoclonal antibody like trastuzumab. Recent progress of systemic therapy with medicals is remarkable, and the educational promotion of experts and medicare circumstances are concluded to be important. (R.T.)

    McNally, Eugene G; Shetty, Shilpa

    2010-09-01

    Plantar fasciopathy is a common cause of heel pain. This article covers the imaging anatomy of the hindfoot, the imaging findings on ultrasound and magnetic resonance imaging (MRI) of plantar fasciopathy, plantar fibromas, trauma, Achilles tendonopathy, neural compression, stress fractures of the os calcis and other heel pad lesions. Thickening of the plantar fascia insertion more than 5 mm either on ultrasound or MRI is suggestive of plantar fasciopathy. Ultrasound is superior to MRI for diagnosis of plantar fibroma as small low signal lesions on MRI are similar to the normal plantar fascia signal. Ultrasound demonstrates low echogenicity compared with the echogenic plantar fascia. Penetrating injuries can appear bizarre due to associated foreign body impaction and infection. Achilles tendonopathy can cause heel pain and should be considered as a possible diagnosis. Treatment options include physical therapy, ECSWT, corticosteroid injection, and dry needling. Percutaneous US guided treatment methods will be described. Thieme Medical Publishers.

    Upper limb apraxia, a disorder of higher motor cognition, is a common consequence of left-hemispheric stroke. Contrary to common assumption, apraxic deficits not only manifest themselves during clinical testing but also have delirious effects on the patients’ everyday life and rehabilitation. Thus, a reliable diagnosis and efficient treatment of upper limb apraxia is important to improve the patients’ prognosis after stroke. Nevertheless, to date, upper limb apraxia is still an underdiagnosed...

    Full Text Available The article deals with clinical diagnosis and treatment of pityriasis rubra pilaris (PRP. The authors analyze the diagnostic errors, present literature review, and their own observations. The clinical study included 23 patients with pityriasis rubra pilaris: 18 women and 5 men, average age of 54 ± 7.2. The clinical diagnosis of all examined patients was subsequently confirmed by histological analysis of the skin. The primary clinical diagnosis was psoriasis in 15 (65.2% patients, 6 (26% patients received treatment for toxic exanthema, and only 2 (8.8% patients were presumptively diagnosed with pityriasis rubra pilaris. In conclusion, pityriasis rubra pilaris was initially misdiagnosed in 91.2% of patients. Considering the great number of diagnostic errors, we analyzed the main diagnostic and differential diagnostic features of PRP. The most effective of all synthetic retinoids in PRP treatment is acitretin. Although symptomatic improvement in PRP occurs within a month, substantial improvement, even clearing is possible within 4 - 6 months.

    There are several methods to detect ASA. In the past, the clinical interest in ASA was hampered by the fact that a standardized assay for the detection of ASA was lacking. However, it has to be clarified whether each antibody binding to an antigen, which is identified on the sperm surface, also influences sperm function. Several methods have been reported for treatment of immunoinfertility. Most of the available techniques have side effects, are invasive and expensive, have low efficacy, or provide conflicting results.This review article will help to increase our knowledge about diagnosis and treatment methods of ASA.

    2009-08-01

    Granulomatous lobular mastitis is a rare chronic inflammatory disease that has clinical and radiologic findings similar to those of breast cancer. We performed a retrospective analysis of clinical, imaging, and treatment findings in 54 women diagnosed with granulomatous lobular mastitis between January 2000 and April 2008. The imaging findings of granulomatous lobular mastitis overlap with those of malignancy. The most common presentation is a focal asymmetric density on mammography and an irregular hypoechoic mass with tubular extensions on ultrasound. Core biopsy is typically diagnostic. Once the diagnosis is established by tissue sampling, corticosteroids are the first line of treatment.

    Puschmann, Andreas; Wszolek, Zbigniew K.

    2014-01-01

    Tremor is the most common movement disorder presenting to an outpatient neurology practice and is defined as a rhythmical, involuntary oscillatory movement of a body part. The authors review the clinical examination, classification, and diagnosis of tremor. The pathophysiology of the more common forms of tremor is outlined, and treatment options are discussed. Essential tremor is characterized primarily by postural and action tremors, may be a neurodegenerative disorder with pathologic changes in the cerebellum, and can be treated with a wide range of pharmacologic and nonpharmacologic methods. Tremor at rest is typical for Parkinson’s disease, but may arise independently of a dopaminergic deficit. Enhanced physiologic tremor, intention tremor, and dystonic tremor are discussed. Further differential diagnoses described in this review include drug- or toxin-induced tremor, neuropathic tremor, psychogenic tremor, orthostatic tremor, palatal tremor, tremor in Wilson’s disease, and tremor secondary to cerebral lesions, such as Holmes’ tremor (midbrain tremor). An individualized approach to treatment of tremor patients is important, taking into account the degree of disability, including social embarrassment, which the tremor causes in the patient’s life.

    Full Text Available Emiliano Antiga, Marzia Caproni Department of Surgery and Translational Medicine, Section of Dermatology, University of Florence, Florence, Italy Abstract: Dermatitis herpetiformis (DH is an inflammatory cutaneous disease with a chronic relapsing course, pruritic polymorphic lesions, and typical histopathological and immunopathological findings. According to several evidences, DH is considered the specific cutaneous manifestation of celiac disease, and the most recent guidelines of celiac disease have stated that, in celiac patients with a proven DH, a duodenal biopsy is unnecessary for the diagnosis. In this review, the most recent data about the diagnosis and the management of DH have been reported and discussed. In particular, in patients with clinical and/or histopathological findings suggestive for DH, the finding of granular IgA deposits along the dermal–epidermal junction or at the papillary tips by direct immunofluorescence (DIF assay, together with positive results for anti-tissue transglutaminase antibody testing, allows the diagnosis. Thereafter, a gluten-free diet should be started in association with drugs, such as dapsone, that are able to control the skin manifestations during the first phases of the diet. In conclusion, although DH is a rare autoimmune disease with specific immunopathological alterations at the skin level, its importance goes beyond the skin itself and may have a big impact on the general health status and the quality of life of the patients.

    Suga, Kazuyoshi

    2010-01-01

    Ventilation (V)-perfusion (Q) single photon emission computed tomography (SPECT) provides important information of functional impairment in various lung diseases, and often sensitively detects CT-undetectable lesions. V·Q SPECT also provides objective and quantitative assessment of severity of lung functional impairment. Functional-morphological correlation on V·Q SPECT-CT fusion images further facilitates these advantages of V·Q SPECT. This article describes clinical feasibility of V·Q SPECT in functional assessment and diagnosis of chronic obstructive pulmonary diseases, pulmonary embolism, pulmonary hypertension, interstitial lung diseases, and lung right-to-left shunt diseases. This article hopefully provides sufficient responses to the crucial query of ''Is CT imaging alone really sufficient for diagnosis and pathophysiological assessment of various lung diseases?''

    To explore the diagnosis and treatment methods of pediatric anismus. Twenty-nine patients with idiopathic chronic constipation, diagnosed with anismus by colon barium contrast and anorectal manometry from Nov. 2001 to Nov. 2004 in our hospital, were investigated retrospectively. This group consisted of 13 men and 16 women whose mean age was (6.7+/-4.0) years. Hirschsprung diseases were excluded from the patients by colon barium contrast and rectoanal inhibitory reflex (RAIR) examination. Normal RAIR (5-10 ml elicited) was showed on 21 cases while weakened RAIR (15-30 ml elicited) was showed on 8 cases. After the diagnosis, the patients were treated by toilet training, diet regulation and laxative for 1-2 months. 4 cases were recovered, 5 cases were improved and 20 cases were relied on glycerin suppository. Four cases, relied on glycerin suppository, underwent Lynn procedure and had good results after 5-24 months follow-up. Two cases were re-examined by anorectal manometry 3 and 6 months after surgery, the resting pressure and the high pressure zone (HPZ) decreased, but the simulation defecation reflex was still abnormal. The diagnosis of pediatric anismus relies on history of constipation, combined with anorectal manometry and colon barium contrast. Lynn procedure could be chosen for the patients unsatisfied in toilet training and other non-operative treatment.

    The diagnosis of traumatic pancreatic injury in the acute stage is difficult to establish blood tests and abdominal findings alone. Moreover, to determine treatment strategies, it is important not only that a pancreatic injury is diagnosed but also whether a pancreatic ductal injury can be found. At our center, to diagnose isolated pancreatic injuries, we actively perform endoscopic retrograde pancreatography (ERP) in addition to abdominal CT at the time of admission. For cases with complications such as abdominal and other organ injuries, we perform a laparotomy to ascertain whether a pancreatic duct injury is present. In regard to treatment options, for grade III injuries to the pancreatic body and tail, we basically choose distal pancreatectomy, but we also consider the Bracy method depending on the case. As for grade III injuries to the pancreatic head, we primarily choose pancreaticoduodenectomy, but also apply drainage if the situation calls for it. However, pancreatic injuries are often complicated by injuries of other regions of the body. Thus, diagnosis and treatment of pancreatic injury should be based on a comprehensive decision regarding early prioritization of treatment, taking hemodynamics into consideration after admission, and how to minimize complications such as anastomotic leak and pancreatic fistulas.

    1994-01-01

    Endoscopic retrograde cholangiopancreatography (ERCP) was carried out for the first time in 1968. Five years later endoscopic sphincterotomy was performed. Since then both modalities have become established as necessary adjuncts in the diagnosis and treatment of patients with pathology in the bile duct or pancreas. The main indication is common bile duct stone, and as a consequence of this treatment fewer patients are now treated surgically. Patients with malignant bile duct obstruction can be given reasonable palliation of both jaundice and pruritus and therefore improved quality of life. Some reports indicate that endoscopic drainage may be useful for pancreatic stenosis. Complications are few, but vigilance and prompt treatment is necessary to keep morbidity at a minimum. Follow-up after several years shows that sphincterotomy is successful also in the long term. The authors discuss the present diagnostic and therapeutic situation. 31 refs., 2 tabs

    Background Lyme disease is an emerging zoonotic infection in Canada. As the Ixodes tick expands its range, more Canadians will be exposed to Borrelia burgdorferi, the bacterium that causes Lyme disease. Objective To review the clinical diagnosis and treatment of Lyme disease for front-line clinicians. Methods A literature search using PubMed and restricted to articles published in English between 1977 and 2014. Results Individuals in Lyme-endemic areas are at greatest risk, but not all tick bites transmit Lyme disease. The diagnosis is predominantly clinical. Patients with Lyme disease may present with early disease that is characterized by a “bull’s eye rash”, fever and myalgias or with early disseminated disease that can manifest with arthralgias, cardiac conduction abnormalities or neurologic symptoms. Late Lyme disease in North America typically manifests with oligoarticular arthritis but can present with a subacute encephalopathy. Antibiotic treatment is effective against Lyme disease and works best when given early in the infection. Prophylaxis with doxycyline may be indicated in certain circumstances. While a minority of patients may have persistent symptoms, evidence does not demonstrate that prolonged courses of antibiotics improve outcome. Conclusion Clinicians need to be aware of the signs and symptoms of Lyme disease. Knowing the regions where Borrelia infection is endemic in North America is important for recognizing patients at risk and informing the need for treatment. PMID:29769842

    Badillo, Raul; Francis, Dawn

    2014-01-01

    Gastroesophageal reflux disease (GERD) is a common disease with a prevalence as high as 10%-20% in the western world. The disease can manifest in various symptoms which can be grouped into typical, atypical and extra-esophageal symptoms. Those with the highest specificity for GERD are acid regurgitation and heartburn. In the absence of alarm symptoms, these symptoms can allow one to make a presumptive diagnosis and initiate empiric therapy. In certain situations, further diagnostic testing is needed to confirm the diagnosis as well as to assess for complications or alternate causes for the symptoms. GERD complications include erosive esophagitis, peptic stricture, Barrett’s esophagus, esophageal adenocarcinoma and pulmonary disease. Management of GERD may involve lifestyle modification, medical therapy and surgical therapy. Lifestyle modifications including weight loss and/or head of bed elevation have been shown to improve esophageal pH and/or GERD symptoms. Medical therapy involves acid suppression which can be achieved with antacids, histamine-receptor antagonists or proton-pump inhibitors. Whereas most patients can be effectively managed with medical therapy, others may go on to require anti-reflux surgery after undergoing a proper pre-operative evaluation. The purpose of this review is to discuss the current approach to the diagnosis and treatment of gastroesophageal reflux disease. PMID:25133039

The paper considers the causes of muscle pains, laboratory and instrumental studies (immunological tests, determination of the level of specific muscular enzymes, primarily creatine phosphokinase – CPK, etc., and the main reasons for enhanced plasma CPK activity. It also describes acute and chronic mialgias associated with enhanced plasma CPK activity, as well as diseases in which mialgias are related to the normal level of CPK, myofascial syndrome (MFS and fibromyalgia (FM in particular. The characteristic features of MFS are given in its diagnostic criteria. It is stated that a differential diagnosis should be made between MFS and major muscle pain-associated abnormalities, such as polymyalgia rheumatica, FM, etc. Diagnosticcriteria for polymyalgia rheumatica are given. A MFS treatment algorithm is presented. Local exposure methods applied to altered musculoligamentous structures in combination with myorelaxants and non-steroidal anti-inflammatory drugs assume paramount importance in MFS.

    Leprosy is an infectious disease that has now been reported for more than 2000 years. The leprosy elimination goal set by the World Health Organization (WHO), i.e. a global prevalence rate Leprosy is a specific infection: (i) it is a chronic infection primarily affecting the skin and peripheral nerves, (ii) Mycobacterium leprae is one of the last bacterial species of medical interest that cannot be cultured in vitro (mainly because of its reductive genome evolution), and (iii) transmission and pathophysiological data is still limited. The various presentations of the disease (Ridley-Jopling and WHO classifications) are correlated with the patient's immune response, bacillary load, and by the delay before diagnosis. Multidrug therapy (dapsone, rifampicin, with or without clofazimine) has been recommended since 1982 as the standard treatment of leprosy; 6 months for patients presenting with paucibacillary leprosy and 12 months for patients presenting with multibacillary leprosy. The worldwide use of leprosy drugs started in the 1980s and their free access since 1995 contributed to the drastic decline in the number of new case patients. Resistant strains are however emerging despite the use of multidrug therapy; identifying and monitoring resistance is still necessary. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Objectives: The objective of our study was to review the current knowledge on the diagnosis and treatment options of plateau iris configuration and syndrome. Systematic review methodology: Relevant publications on plateau iris that were published until 2014. Conclusions: Plateau iris syndrome is a form of primary angle closure glaucoma caused by a large or anteriorly positioned ciliary body that leads to mechanical obstruction of trabecular meshwork. This condition is most often found in younger patients. Plateau iris has been considered an abnormal anatomic variant of the iris that can be diagnosed on ultrasound biomicroscopy or optical coherence tomography of anterior segment. Patients with plateau iris syndrome can be recognized by the lack of response in angle opening after iridotomy. The treatment of choice in these cases is argon laser peripheral iridoplasty PMID:27373109

    Celiac disease (CD) is one of the most common diseases, resulting from both environmental (gluten) and genetic factors [human leukocyte antigen (HLA) and non-HLA genes]. The prevalence of CD has been estimated to approximate 0.5%-1% in different parts of the world. However, the population with diabetes, autoimmune disorder or relatives of CD individuals have even higher risk for the development of CD, at least in part, because of shared HLA typing. Gliadin gains access to the basal surface of the epithelium, and interact directly with the immune system, via both trans- and para-cellular routes. From a diagnostic perspective, symptoms may be viewed as either “typical” or “atypical”. In both positive serological screening results suggestive of CD, should lead to small bowel biopsy followed by a favourable clinical and serological response to the gluten-free diet (GFD) to confirm the diagnosis. Positive anti-tissue transglutaminase antibody or anti-endomysial antibody during the clinical course helps to confirm the diagnosis of CD because of their over 99% specificities when small bowel villous atrophy is present on biopsy. Currently, the only treatment available for CD individuals is a strict life-long GFD. A greater understanding of the pathogenesis of CD allows alternative future CD treatments to hydrolyse toxic gliadin peptide, prevent toxic gliadin peptide absorption, blockage of selective deamidation of specific glutamine residues by tissue, restore immune tolerance towards gluten, modulation of immune response to dietary gliadin, and restoration of intestinal architecture.

    Full Text Available The problem of echinococcosis, despite the progress made in its diagnosis and treatment, currently remains poorly understood and highly relevant in pediatric Parasitology. Studies of many authors show that in recent years the number of patients with echinococcosis not only universally recognized endemic foci, but also among people in the European region, including in countries such as Romania, Germany, Austria. However, studies on the prevalence and structure of echinococcosis among children in Ukraine, are not held. Despite the large number of papers devoted to the treatment of echinococcosis, the problem of the treatment of this disease in children is still far from its final decision. Usually offered surgical treatment, which is not possible with multiple lesions of the liver or other organs. All this shows the relevance and importance for practical public health issues for further study of diagnosis and treatment of echinococcosis in children. The purpose of the study. A comparative analysis of the diagnostic efficacy of X-ray and ultrasound method in the diagnosis of echinococcosis in children. Material & methods. This work is based on a survey of 39 children with hepatic echinococcosis, were examined at the Department of Medical Parasitology and Tropical Diseases Kharkiv Medical Academy of Postgraduate Education from 2005 to 2015. Boys was 1.5 times greater (59.5% than girls - 40.5%. Children under five years of age accounted for only 4.0% of all patients, due to their limited contact with the environment when compared with older age. The greatest risk of disease was in the 10- 13 years of age, the number of children in the group reached 40.3% of the patients. The vast majority of patients (89.6% lived in rural areas. In this case, the parents of sick children from the village were engaged in farming, were in personal use livestock, dogs, which probably contributed to the invasion.

    Ophthalmologic conditions were among the earliest described findings in patients with the acquired immunodeficiency syndrome (AIDS). The purpose of this review is to highlight recent changes in the pathophysiology and management of ophthalmologic conditions in patients infected with the human immunodeficiency virus (HIV). The introduction of highly active antiretroviral therapy (HAART) in 1996 changed ophthalmologic findings from predominantly acute infectious diseases to chronic, slowly progressive, debilitating conditions. HIV-associated neuroretinal disorder infrequently leads to blindness, but it causes visual disability in a large percentage of patients. Cytomegalovirus retinitis is now seen less commonly in the USA, but it remains an important cause of blindness in HIV-infected patients from developing countries. Immune recovery uveitis has emerged as a major cause of visual disability in the USA. As HIV has become a chronic disease, visual disability due to chronic noninfectious diseases have become increasingly important.

    Full Text Available Tuberculous meningitis (TBM is the most common form of central nervous system tuberculosis (TB and has very high morbidity and mortality. TBM is typically a subacute disease with symptoms that may persist for weeks before diagnosis. Characteristic cerebrospinal fluid (CSF findings of TBM include a lymphocytic-predominant pleiocytosis, elevated protein, and low glucose. CSF acid-fast smear and culture have relatively low sensitivity but yield is increased with multiple, large volume samples. Nucleic acid amplification of the CSF by PCR is highly specific but suboptimal sensitivity precludes ruling out TBM with a negative test. Treatment for TBM should be initiated as soon as clinical suspicion is supported by initial CSF studies. Empiric treatment should include at least four first-line drugs, preferably isoniazid, rifampin, pyrazinamide, and streptomycin or ethambutol; the role of fluoroquinolones remains to be determined. Adjunctive treatment with corticosteroids has been shown to improve mortality with TBM. In HIV-positive individuals with TBM, important treatment considerations include drug interactions, development of immune reconstitution inflammatory syndrome, unclear benefit of adjunctive corticosteroids, and higher rates of drug-resistant TB. Testing the efficacy of second-line and new anti-TB drugs in animal models of experimental TBM is needed to help determine the optimal regimen for drug-resistant TB.

    Most dental pain is caused by an organic problem such as dental caries, periodontitis, pulpitis, or trauma. Diagnosis and treatment of these symptoms are relatively straightforward. However, patients often also complain of abnormal dental pain that has a non-dental origin, whose diagnosis is challenging. Such abnormal dental pain can be categorized on the basis of its cause as referred pain, neuromodulatory pain, and neuropathic pain. When it is difficult to diagnose a patient's dental pain, these potential alternate causes should be considered. In this clinical review, we have presented a case of referred pain from the digastric muscle (Patient 1), of pulpectomized (Patient 2), and of pulpectomized pain (Patient 3) to illustrate referred, neuromodulatory, and neuropathic pain, respectively. The Patient 1 was advised muscle stretching and gentle massage of the trigger points, as well as pain relief using a nonsteroidal anti-inflammatory and the tricyclic antidepressant amitriptyline. The pain in Patient 2 was relieved completely by the tricyclic antidepressant amitriptyline. In Patient 3, the pain was controlled using either a continuous drip infusion of adenosine triphosphate or intravenous Mg2+ and lidocaine administered every 2 weeks. In each case of abnormal dental pain, the patient's diagnostic chart was used (Fig.2 and 3). Pain was satisfactorily relieved in all cases.

    Intracranial plasmocytomas are a rare abnormality in a neurosurgeon's practice. The plasmocytomas may originate from the skull bones or soft tissue intracranial structures; they may be solitary or occur as a manifestation of multiple myeloma, this type being typical of most intracranial plasmocytomas. Progression of solitary plasmocytoma to multiple myeloma is observed in a number of cases. Preoperative diagnosis involves computed tomography or magnetic resonance imaging; angiography is desirable. The final diagnosis of plasmocytoma is chiefly based on a morphological study. Special immunohistochemical studies yield very promising results; these are likely to be of high prognostic value. Intracranial plasmocytomas require a differential approach and a meticulous examination since the presence or absence of multiple myeloma radically affects prognosis. There are well-defined predictors; however, it is appropriate that craniobasal plasmocytomas show a worse prognosis than plasmocytomas of the skull vault and more commonly progress to multiple myeloma. Plasmocytomas respond to radiotherapy very well. The gold standard of treatment for plasmocytoma is its total removal and adjuvant radiation therapy; however, there is evidence for good results when it is partially removed and undergoes radiotherapy or after radical surgery without subsequent radiation. The role of chemotherapy has not been defined today.

    Pompe disease is a rare, progressive and often fatal neuromuscular disorder. It is caused by a deficiency of the lysosomal alpha-glucosidase. Among glycogen storage disorders, it is one of the most common. Its clinical manifestations can start at any moment of life, with a very variable symptomatology. In this article, we show an extended revision of the literature in regards to the main medical aspects of Pompe disease: etiology, psychopathology, epidemiology, clinical variants, pathological diagnosis, and enzyme replacement therapy. With this information, we created a diagnostic and therapeutic guide, which is addressed to specialists and to first-level physicians, in order to let them identify both the classic and the late forms of this disease. We describe as well the best, timely, multidisciplinary treatment in use. Also, we show some suggestions to the proper functioning of health institutions, and routes to diagnosis. We conclude that Pompe disease may be properly diagnosed and treated if health care professionals follow the internationally approved recommendations.

    Prostate inflammation is a common syndrome, especially in men under 50. It usually presents with voiding symptoms and pain in the genitourinary area, and sometimes as sexual dysfunction. Based on clinical and laboratory characteristics, prostatitis is classified as acute bacterial prostatitis, chronic bacterial prostatitis, chronic inflammatory and non-inflammatory prostatitis or chronic pelvic pain syndrome, and asymptomatic inflammatory prostatitis. Bacterial prostatitis is most often caused by infection with uropathogens, mainly Gram-negative bacilli, but Gram-positive and atypical microorganisms have also been identified as causative organisms of chronic prostatitis. According to reports by several authors, Chlamydia trachomatis and Trichomonas vaginalis are some of the most common pathogens, making chronic prostatitis a sexually transmitted disease. Diagnosis and treatment of acute and chronic bacterial prostatitis in particular can be challenging.

    2016-01-01

    Milk fistula is an uncommon condition which occurs when there is an abnormal connection that forms between the skin surface and the duct in the breast of a lactating woman, resulting in spontaneous and often constant drainage of milk from this path of least resistance. A milk fistula is usually a complication that results from a needle biopsy or surgical intervention in a lactating patient. Here, the authors present an unusual case of a spontaneous milk fistula which developed from an abscess in the breast of a lactating woman. The patient initially presented to the office with a large open wound on her breast, formed from skin breakdown, within which milk was pooling. She was treated with local wound care and cessation of breastfeeding, with appropriate healing of the wound and closure of the fistula with 6 weeks. Diagnosis, prevention, and treatment of milk fistula were reviewed. © 2015 Wiley Periodicals, Inc.

    Full Text Available Despite the existence of a government-run tuberculosis (TB control program, the current nationwide burden of TB continues to be a public health problem in Taiwan. Intense current and previous efforts into diagnostic, therapeutic, and preventive interventions have focused on TB in adults, but childhood TB has been relatively neglected. Children are particularly vulnerable to severe disease and death following infection, and children with latent infections become reservoirs for future transmission following disease reactivation in adulthood, thus fueling future epidemics. Additional research, understanding, and prevention of childhood TB are urgently needed. This review assesses the epidemiology, diagnosis, treatment, and relevant principles of TB vaccine development and presents efficacy data for the currently licensed vaccines.

    Burnout syndrome is a socio-psychological phenomenon of emotional, motivational, and physical exhaustion as a result of chronic occupational stress. It is manifested as long-term emotional exhaustion, depersonalization and diminished personal and professional achievements. Burnout syndrome is common among health care workers, 'due to their high dedication, empathy for suffering patients, and decision-making related to life and health of patients. Personal, role and organizational factors influence on development of burnout. The clinical picture of burnout is multifactorial and can be described as a set of psychosomatic and somatic disorders, symptoms of social dysfunction. Diversity and non-specific symptoms of burnout syndrome determine the need for an interdisciplinary approach to its diagnosis. The leading role in solving problems related to stress and emotional burnout plays psychotherapy. The paper presents diagnostic criteria, risk factors, and methods of prevention and treatment of emotional burnout.

    Endoscopy allows for the screening, early diagnosis, treatment and follow up of superficial esophageal cancer. Endoscopic submucosal dissection has become the gold standard for the resection of superficial squamous cell neoplasia. Combinations of endoscopic mucosal resection and radiofrequency ablation are the mainstay of the management of Barrett's associated neoplasia. However, protruded, non-lifting or large lesions may be better managed by endoscopic submucosal dissection. Novel ablation tools, such as argon plasma coagulation with submucosal lifting and cryoablation balloons, are being developed for the treatment of residual Barrett's esophagus, since iatrogenic strictures still hamper the development of extensive circumferential resections in the esophagus. Optimal surveillance modalities after endoscopic resection are still to be determined. The assessment of the risk of lymph-node metastases, as well as of the need for additional treatments based on qualitative and quantitative histological criteria, balanced to the patient's condition, requires a dedicated multidisciplinary team decision process. The need for trained endoscopists, expert pathologists and surgeons, and specialized multidisciplinary meetings underlines the role of expert centers in the management of superficial esophageal cancer.

    This course addresses radiologic aspects of diagnosis and treatment of renal calculi. The combined clinical experience from two institutions (UCLA and Mayo Clinic) of over 3,000 extracorporeal shock wave lithotripsy (ESWL) treatments is presented, as is the new developmental designs and socioeconomic impact. ESWL has radically altered the management of renal and ureteral calculi. An underwater shock wave is concentrated on a calculus, which shatters after being subjected to a number of shocks. Small fragments are usually passed spontaneously, making the patient stone free and eliminating the need for surgery. Radiology plays an important role in this patient population. The presence of radiopaque and radiolucent calculi - their size, number, and location; the anatomic appearance of the kidneys, pelvocalyceal system, and ureter; anatomic variants; and pathologic conditions such as horseshoe kidneys, ureteropelvic junction narrowing, polycystic kidney disease, calyceal diverticuli, infundibular stenosis, ureteral obstruction, and medullary sponge kidney are best imaged with excretory urography and occasionally retrograde pyelography and US. Follow-up examinations usually consist of abdominal radiography and US if obstruction is suspected. The percutaneous approach still plays a major albeit obviously diminished role in treatment and may be used for a number of specific indications, which is discussed

    Cervical vertigo is characterized by vertigo from the cervical spine. However, whether cervical vertigo is an independent entity still remains controversial. In this narrative review, we outline the basic science and clinical evidence for cervical vertigo according to the current literature. So far, there are 4 different hypotheses explaining the vertigo of a cervical origin, including proprioceptive cervical vertigo, Barré-Lieou syndrome, rotational vertebral artery vertigo, and migraine-associated cervicogenic vertigo. Proprioceptive cervical vertigo and rotational vertebral artery vertigo have survived with time. Barré-Lieou syndrome once was discredited, but it has been resurrected recently by increased scientific evidence. Diagnosis depends mostly on patients' subjective feelings, lacking positive signs, specific laboratory examinations and clinical trials, and often relies on limited clinical experiences of clinicians. Neurological, vestibular, and psychosomatic disorders must first be excluded before the dizziness and unsteadiness in cervical pain syndromes can be attributed to a cervical origin. Treatment for cervical vertigo is challenging. Manual therapy is recommended for treatment of proprioceptive cervical vertigo. Anterior cervical surgery and percutaneous laser disc decompression are effective for the cervical spondylosis patients accompanied with Barré-Liéou syndrome. As to rotational vertebral artery vertigo, a rare entity, when the exact area of the arterial compression is identified through appropriate tests such as magnetic resonance angiography (MRA), computed tomography angiography (CTA) or digital subtraction angiography (DSA) decompressive surgery should be the chosen treatment.

    In this article we summarized the recent research of the food addiction, diagnosis, treatment and prevention, which is carried out in this area. The concept of food addiction is new and complex, but proven to be very important for understanding and solving the problem of obesity. First part of this paper emphasizes the neurological studies, whose results indicate the similarity of brain processes that are being activated during drug abuse and during eating certain types of food. In this context, different authors speak of "hyper-palatable", industrial food, saturated with salt, fat and sugar, which favor an addiction. In the section on diagnostic and instruments constructed for assessing the degree of dependence, main diagnostic tool is standardized Yale Food Addiction Scale constructed by Ashley Gearhardt, and her associates. Since 2009, when it was first published, this scale is used in almost all researches in this area and has been translated into several languages. Finally, distinguish between prevention and treatment of food addiction was made. Given that there were similarities with other forms of addictive behavior, the researchers recommend the application of traditional addiction treatment.

    Full Text Available Halitosis or oral malodor is not a diagnosis, but is symptom. Halitosis, that we frequently encounter in ear, nose and throat practice can be the harbinger of some serious underlying disease. Therefore, diagnosis and to find the cause of the halitosis are important. Also halitosis treatment is necessary due to the social and psychological effects. Breath contains hundreds of volatile organic compounds that are by-products of our metabolism. Certain diseases such as nasopharynx cancer, larynx cancer ve lung cancer alter the mix of gases. Thus, the analysis of exhaled air has gained importance. New technologies lead to the development of new devices. And with these called electronic noses the analysis of exhaled air has becomes an important non-invasive diagnostic method. In the literature, halitosis and bad breath which is used as synonymus with oral malodor is the emission of unpleasant odor from mouth and nasal passage. It occurs in 25% of the population, approximately and it has a significant social and economic impact. Halitosis is classified as true halitosis (physiologic halitosis and pathologic halitosis, pseudohalitosis and halitophobia. The most common cause is intra-oral diseases. Among all these factors, the most important etiologic factor are the coating tongue. Other ear, nose and throat diseases such as rhinitis and sinusitis are seen among the most common extraoral causes. Treponema denticola, Porphyromonas gingivalis, Tanneralla forsythia, Fusobacterium nucleatum, Prevotella intermedia, Prevotella nigrescens, Actinobacilli and Solobacterium moorei are the bacteria which are commonly isolated from patients with halitosis and they are volatile sulfur compounds (VSCs producing ones as well. The treatment of halitosis should be carried out according to the etiology. In the physiologic halitosis tooth brushing, use of dental floss, tongue cleaning and chlorhexidine, cetylpyridinium chloride and zinc containing antimicrobial mouthwashes

    Full Text Available Background. Galactosemia type I, or classic galactosemia (CG, is the most severe form of hereditary disorders of carbohydrate metabolism, in particular, galactose. Galactosemia is not included in the program of massive neonatal screening in Ukraine. The CG is characterized by the non-specific onset symptoms and leads to high mortality among infants in the neonatal period. The problem of early diagnosis and treatment of infants with CG in the absence of a program for massive neonatal screening in Ukraine requires solution. The purpose was to analyse the clinical and laboratory, molecular genetic features of patients with CG; to define a set of clinical symptoms and to form selective groups of patients for administration of diet therapy and laboratory diagnosis; to develop schemes-stages of effective early diagnosis and treatment of patients with CG in the absence of mass neonatal screening in order to reduce infant mortality and prevent the disability of patients with this pathology. Materials and methods. In 2014–2017, 317 patients with a diagnosis of hepatitis of uncertain origin were examined. The age of patients ranged from 3 days to 16 years; 145 (45 % of them were males, 172 (55 % — females. In all patients, a polysyndromic clinical picture with predominant lesion in the liver function was observed. All patients were examined for the activity of galactose-1-phosphate uridylyltransferase (GALT enzyme in the red blood cells and underwent DNA diagnosis for the detection of major mutations in the GALT gene. All patients were examined for viral hepatitis, underwent biochemical blood tests for hepatic transaminases, alkaline phosphatase, bilirubin levels, and coagulopathy. Tandem mass spectrometry was also performed to exclude or confirm the metabolic imbalance of amino acids, organic acids, and mitochondrial beta-oxi­dation of fatty acids.

    Idiopathic achalasia is an archetype esophageal motor disorder, causing significant impairment of eating ability and reducing quality of life. The pathophysiological underpinnings of this condition are loss of esophageal peristalsis and insufficient relaxation of the lower esophageal sphincter (LES). The clinical manifestations include dysphagia for both solids and liquids, regurgitation of esophageal contents, retrosternal chest pain, cough, aspiration, weight loss and heartburn. Even though idiopathic achalasia was first described more than 300 years ago, researchers are only now beginning to unravel its complex etiology and molecular pathology. The most recent findings indicate an autoimmune component, as suggested by the presence of circulating anti-myenteric plexus autoantibodies, and a genetic predisposition, as suggested by observed correlations with other well-defined genetic syndromes such as Allgrove syndrome and multiple endocrine neoplasia type 2 B syndrome. Viral agents (herpes, varicella zoster) have also been proposed as causative and promoting factors. Unfortunately, the therapeutic approaches available today do not resolve the causes of the disease, and only target the consequential changes to the involved tissues, such as destruction of the LES, rather than restoring or modifying the underlying pathology. New therapies should aim to stop the disease at early stages, thereby preventing the consequential changes from developing and inhibiting permanent damage. This review focuses on the known characteristics of idiopathic achalasia that will help promote understanding its pathogenesis and improve therapeutic management to positively impact the patient's quality of life.

A particular aspect of DFU that has not been reviewed extensively thus far is its management in conjunction with peripheral limb edema. Peripheral limb edema is a feature of diabetes that has been identified as a significant risk factor for amputation in patients with DFU. Three major etiological factors in development of lymphedema with concurrent DFU are diabetic microangiopathy, failure of autonomic regulation, and recurrent infection. This review outlines the pathophysiology of lymphedema formation in patients with DFU and highlights the cellular and immune components of impaired wound healing in lymphedematous DFU. We then discuss the principles of management of DFU in conjunction with lymphedema.Keywords: diabetic foot ulcer, lymphedema, chronic wound, wound management

    Full Text Available The paper presented the results of diagnostics and treatment of patients with diagnosis of chondroblastoma, treated at the Institute of Orthopedic Surgery "Banjica", Belgrade. A total of 30 patients were analyzed, involving the period from 1975-2004. All important data were obtained using the complete medical documentation, physical examination, radiographic findings and available additional diagnostic procedures. The proximal part of tibia, the proximal part of humerus and the distal part of femur were the most common sites of tumor, accounting for 63% of cases. Higher incidence of chondroblastoma was found in male patients, especially in the second decade of life. Pathohistological tumor verification was done in all patients. The patients were then treated by different surgical procedures, both on account of primary lesion and recurrence. Curettage and osteoplasty using the auto- and homograft were carried out in 21 patients, wide resection in nine cases, and amputation was performed in three cases. One patient had radiotherapy due to recurrence of lesion, nevertheless malignant transformation of chondroblastoma occurred in time. Seven patients manifested local recurrence, and one of them even had relapse on two occasions and malignant transformation of chondroblastoma. Malignant lesions were found in three cases (10% of patients; one lesion was diagnosed as primary while other two malignancies were detected only after recurrence, and the treatment was completed by lower leg amputation.

    Spinal nerve roots have a peculiar structure, different from the arrangements in the peripheral nerve. The nerve roots are devoid of lymphatic vessels but are immersed in the cerebrospinal fluid (CSF) within the subarachnoid space. The blood supply of nerve roots depends on the blood flow from both peripheral direction (ascending) and the spinal cord direction (descending). There is no hypovascular region in the nerve root, although there exists a so-called water-shed of the bloodstream in the radicular artery itself. Increased mechanical compression promotes the disturbance of CSF flow, circulatory disturbance starting from the venous congestion and intraradicular edema formation resulting from the breakdown of the blood-nerve barrier. Although this edema may diffuse into CSF when the subarachnoid space is preserved, the endoneurial fluid pressure may increase when the area is closed by increased compression. On the other hand, the nerve root tissue has already degenerated under the compression and the numerous macrophages releasing various chemical mediators, aggravating radicular symptoms that appear in the area of Wallerian degeneration. Prostaglandin E1 (PGE1) is a potent vasodilator as well as an inhibitor of platelet aggregation and has therefore attracted interest as a therapeutic drug for lumbar canal stenosis. However, investigations in the clinical setting have shown that PGE1 is effective in some patients but not in others, although the reason for this is unclear.

    Full Text Available Children regularly and voluntarily go to school in order to fulfill the expectations of society from them to continue their education or schooling. School continuation has been made compulsory by laws. Nonetheless, contrary to popular belief, for some children it is distressing to go to school. These children have difficulty continuing school and/or refuse to go to school. Today school refusal is defined as a child’s inability to continue school for reasons, such as anxiety and depression. The prevalence of school refusal has been reported to be approximately 1% in school-age children and 5% in child psychiatry samples. The prevalence of school refusal is similar among boys and girls. School refusal can occur at any time throughout the child’s academic life and at all socio-economic levels. School refusal is considered a symptom rather than a clinical diagnosis and can manifest itself as a sign of many psychiatric disorders, with anxiety disorders predominant. Separation anxiety disorder, generalized anxiety disorder, social phobia, specific phobia, and adjustment disorder with anxiety symptoms are the most common disorders co-occurring with school refusal. While separation anxiety disorder is associated with school refusal in younger children, other anxiety disorders, especially phobias, are associated with school refusal in adolescents. Children who have parents with psychiatric disorders have a higher incidence of school refusal, and psychiatric disorders are more frequently seen in adult relatives of children with school refusal, which supports a significant role of genetic and environmental factors in th etiology of school refusal. School refusal is a emergency state for child mental health. As it leads to detrimental effects in the short term and the long term, it should be regarded as a serious problem. The long-lasting follow-up studies of school refusing children have revealed that these children have a higher incidence of

    Full Text Available Aortic stenosis is the most frequent valvular heart disease. Aortic sclerosis is the first characteristic lesion of the cusps, which is considered today as the process similar to atherosclerosis. Progression of the disease is an active process leading to forming of bone matrix and heavily calcified stiff cusps by inflammatory cells and osteopontin. It is a chronic, progressive disease which can remain asymptomatic for a long time even in the presence of severe aortic stenosis. Proper physical examination remains an essential diagnostic tool in aortic stenosis. Recognition of characteristic systolic murmur draws attention and guides further diagnosis in the right direction. Doppler echocardiography is an ideal tool to confirm diagnosis. It is well known that exercise tests help in stratification risk of asymptomatic aortic stenosis. Serial measurements of brain natriuretic peptide during a follow-up period may help to identify the optimal time for surgery. Heart catheterization is mostly restricted to preoperative evaluation of coronary arteries rather than to evaluation of the valve lesion itself. Currently, there is no ideal medical treatment for slowing down the disease progression. The first results about the effect of ACE inhibitors and statins in aortic sclerosis and stenosis are encouraging, but there is still not enough evidence. Onset symptoms based on current ACC/AHA/ESC recommendations are I class indication for aortic valve replacement. Aortic valve can be replaced with a biological or prosthetic valve. There is a possibility of percutaneous aortic valve implantation and transapical operation for patients that are contraindicated for standard cardiac surgery.

    2015-01-01

    Insomnia disorder is characterized by chronic dissatisfaction with sleep quantity or quality that is associated with difficulty falling asleep, frequent nighttime awakenings with difficulty returning to sleep, and/or awakening earlier in the morning than desired. Although progress has been made in our understanding of the nature, etiology, and pathophysiology of insomnia, there is still no universally accepted model. Greater understanding of the pathophysiology of insomnia may provide important information regarding how, and under what conditions, the disorder develops and is maintained as well as potential targets for prevention and treatment. The aims of this report are (1) to summarize current knowledge on the pathophysiology of insomnia and (2) to present a model of the pathophysiology of insomnia that considers evidence from various domains of research. Working within several models of insomnia, evidence for the pathophysiology of the disorder is presented across levels of analysis, from genetic to molecular and cellular mechanisms, neural circuitry, physiologic mechanisms, sleep behavior, and self-report. We discuss the role of hyperarousal as an overarching theme that guides our conceptualization of insomnia. Finally, we propose a model of the pathophysiology of insomnia that integrates the various types of evidence presented. PMID:25846534

    2018-04-01

    Fructose is a natural monosaccharide broadly used in modern society. Over the past few decades, epidemiological studies have demonstrated that high fructose intake is an etiological factor of metabolic syndrome (MetS). This review highlights research advances on fructose-induced MetS, especially the underlying pathophysiological mechanism as well as pharmacotherapy by traditional Chinese medicine (TCM), using the PubMed, Web of science, China National Knowledge Infrastructure, China Science and Technology Journal and Wanfang Data. This review focuses on de novo lipogenesis (DNL) and uric acid (UA) production, two unique features of fructolysis different from glucose glycolysis. High level of DNL and UA production can result in insulin resistance, the key pathological event in developing MetS, mostly through oxidative stress and inflammation. Some other pathologies like the disturbance in brain and gut microbiota in the development of fructose-induced MetS in the past years, are also discussed. In management of MetS, TCM is an excellent representative in alternative and complementary medicine with a complete theory system and substantial herbal remedies. TCMs against MetS or MetS components, including Chinese patent medicines, TCM compound formulas, single TCM herbs and active compounds of TCM herbs, are reviewed on their effects and molecular mechanisms. TCMs with hypouricemic activity, which specially target fructose-induced MetS, are highlighted. And new technologies and strategies (such as high-throughput assay and systems biology) in this field are further discussed. In summary, fructose-induced MetS is a multifactorial disorder with the underlying complex mechanisms. Current clinical and pre-clinical evidence supports the potential of TCMs in management of MetS. Additionally, TCMs may show some advantages against complex MetS as their holistic feature through multiple target actions. However, further work is needed to confirm the effectivity and safety of TCMs

    Ulcerative colitis is a chronic inflammatory disease of the colon that affects the rectum and a variable length of contiguous colon. The disease is characterized by rectal bleeding and diarrhea during periods of exacerbation; these symptoms usually abate with treatment. The pathogenic mechanism of ulcerative colitis is believed to be an aberrant immune response in which antibodies are formed against colonic epithelial protein(s). The disease usually presents during the second and third decades of life, with a smaller peak after the age of 60 years. There is a genetic component to ulcerative colitis, with a higher incidence among family members and, particularly, first-degree relatives. Diagnosis depends on several factors, most notably symptoms, demonstration of uniformly inflamed mucosa beginning in the rectum, and exclusion of other causes of colitis, such as infection. There is no medical cure for ulcerative colitis, but medical therapy is effective and can improve or eliminate symptoms in more than 80% of patients. Surgery offers a cure but carries the high price of total colectomy. New surgical methods, such as ileoanal anastomosis, allow for maintenance of bowel continuity and better patient satisfaction.

    2018-01-01

    Full Text Available soriatic arthritis (PsA is a chronic inflammatory disease of the joints, spine and entheses from a group of spondyloarthritis (SpA, which is usually observed in patients with psoriasis (Ps. The diagnosis of PsA is based on the CASPAR criteria for psoriatic arthritis. The disease results from interactions between genetic, immunological and environmental factors. The main clinical manifestations of PsA include peripheral arthritis, enthesitis, dactylitis, and spondylitis. PsA must be differentiated from rheumatoid arthritis, gout, reactive arthritis, osteoarthritis, and ankylosing spondylitis. Due to the fact that PsA is a clinically heterogeneous disease, its activity is assessed using complex indices, by taking into account that the patient has arthritis, enthesitis, dactylitis, and spondylitis. The goal of treatment for PsA is to achieve remission or minimal activity of the main clinical manifestations of the disease, to slow down or prevent radiographic progression, to increase life expectancy and quality of life in the patients, and to reduce the risk of comorbidities, which is achieved through a wide range of drugs of different classes. Therapy should be chosen based on the clinical manifestations of PsA and comorbidities in the patients.

    Full Text Available [u][/u] Narcolepsy is a chronic hypersomnia characterized by excessive daytime sleepiness (EDS and manifestations of disrupted rapid eye movement sleep stage (cataplexy, sleep paralysis, and hypnagogic/hypnopompic hallucinations. Mechanisms underlying narcolepsy are not fully understood. Experimental data indicate that the disease is caused by a loss of hypocretin neurons in the hypothalamus, likely due to an autoimmune process triggered by environmental factors in susceptible individuals. Most patients with narcolepsy and cataplexy have very low hypocretin-1 levels in the cerebrospinal fluid. An appropriate clinical history, polysomnogram, and multiple sleep latency test are necessary for diagnosis of the disease. Additionally, two biological markers, i.e., cerebrospinal fluid hypocretin-1 levels and expression of the DQB1*0602 gene, are used. The treatment of narcolepsy is aimed at the different symptoms that the patient manifests. Excessive daytime sleepiness is treated with psychostimulants (amphetamine-like, modafinil and armodafinil. Cataplexy is treated with sodium oxybate (GHB, tricyclic antidepressants, or selective serotonin and noradrenaline reuptake inhibitors. Sleep paralysis, hallucinations, and fragmented sleep may be treated with sodium oxybate. Patients with narcolepsy should follow proper sleep hygiene and avoid strong emotions.

    2015-01-01

    Full Text Available The term phenylketonuria encompasses some genetically heterogeneous diseases from a group of hereditary amino acid metabolic disorders, the key biochemical sign of which is a steady increase in blood phenylalanine levels – hyperphenylalaninemia. Phenylketonuria is a most common disease of the above group; its rate in the Russian Federation is 1:7140 neonates. The rare causes of hyperphenylalaninemia include the cofactor (biopterin-deficient forms associated with tetrahydrobiopterin deficiency, leading to the blocked metabolic pathways for converting phenylalanine to tyrosine and for synthesizing catecholamine and serotonin precursors (L-dopa and 5-hydroxytryptophan. The distinguishing feature of all cofactor forms of hyperphenylalaninemia is the inefficiency of an isolated low-protein diet. Cofactor therapy with sapropterin in combination with correction of neuromediatory disorders is used in the combination treatment of these patients. The paper presents a case history of a child with severe biopterin-deficient hyperphenylalaninemia resulting from a defect in the PTS gene. The clinical example illustrates difficulties associated with the diagnosis of cofactor hyperphenylalaninemia and with long individual dosage adjustments for medications. 

  16. Diagnosis and treatment of urethritis in men.

    2010-04-01

    Symptoms of urethritis in men typically include urethral discharge, penile itching or tingling, and dysuria. A diagnosis can be made if at least one of the following is present: discharge, a positive result on a leukocyte esterase test in first-void urine, or at least 10 white blood cells per high-power field in urine sediment. The primary pathogens associated with urethritis are Chlamydia trachomatis and Neisseria gonorrhoeae. Racial disparities in the prevalence of sexually transmitted infections persist in the United States, with rates of gonorrhea 40 times higher in black adolescent males than in white adolescent males. Recent studies have focused on identifying causes of nongonococcal urethritis and developing testing for atypical organisms, such as Mycoplasma genitalium and Ureaplasma species. Less common pathogens identified in patients with urethritis include Trichomonas species, adenovirus, and herpes simplex virus. History and examination findings can help distinguish urethritis from other urogenital syndromes, such as epididymitis, orchitis, and prostatitis. The goals of treatment include alleviating symptoms; preventing complications in the patient and his sexual partners; reducing the transmission of coinfections (particularly human immunodeficiency virus); identifying and treating the patient's contacts; and encouraging behavioral changes that will reduce the risk of recurrence. The combination of azithromycin or doxycycline plus ceftriaxone or cefixime is considered first-line empiric therapy in patients with urethritis. Expedited partner treatment, which involves giving patients prescriptions for partners who have not been examined by the physician, is advocated by the Centers for Disease Control and Prevention and has been approved in many states. There is an association between urethritis and an increased human immunodeficiency virus concentration in semen.

    2009-01-01

    Significant progress in the treatment of soft tissue sarcoma (STS), both primary tumor and local recurrences/metastatic disease, has been achieved in recent years. Surgery is essential modality, but the use of combined treatment (standard combination of surgery with adjuvant radiotherapy, chemotherapy in selected cases and perioperative rehabilitation) in highly-experienced centers increased possibility of cure and limitations of extent of local surgery. Current combined therapy together with the use of reconstructive methods allows for limb-sparing surgery in majority of soft tissue sarcoma patients (amputation in 10% of cases as compared to approximately 50% in the 1960 - 70s). The slow, but constant, increase of rate of soft tissue sarcoma patients with long-term survival has been observed. Contemporary 5-year overall survival rate in patients with extremity soft tissue sarcomas is 55 -78%. In case of diagnosis of metastatic disease the prognosis is still poor (survival of approximately 1 year). Good results of local therapy may be expected only after planned (e.g., after preoperative biopsy - tru - cut or incisional) radical surgical excision of primary tumor with pathologically negative margins (R0 resection). Following appropriate diagnostic check-up, adjuvant radiotherapy is necessary in the majority of patients treated with radical surgery need, as well as long-term rehabilitation and follow-up examinations in treating center are needed for at least 5 years. The progress is due to the introduction of targeted therapy acting on molecular or genetic cellular disturbances detected during studies on etiopathogenetic mechanisms of sarcoma subtypes. In view of rarity of sarcomas and necessity of multidisciplinary therapy, the crucial issue is that management of these tumors should be hold in experienced oncological sarcoma centers. (authors)

    Full Text Available The lecture gives basic information about psoriatic arthritis (PsA, a chronic inflammatory disease of the joints, spine, and enthesises from a group of spondyloarthritis. It describes the epidemiology of the disease and considers current ideas on its pathogenesis and factors influencing the development of PsA in psoriatic patients. The classification and clinical forms of PsA are presented. The major clinical manifestations of the disease are indicated to include peripheral arthritis, enthesitis, dactylitis, and spondylitis. The diagnosis of the disease is noted to be established on the basis of its detected typical clinical and radiological signs, by applying the CASPAR criteria. A dermatologist, rheumatologist, and general practitioner screen PsA, by actively detecting complaints, characteristic clinical and radiological signs of damage to the joints, and/or spine, and/or enthesises and by using screening questionnaires. There are data that patients with PsA are observed to be at higher risk for a number of diseases type 2 diabetes mellitus hypertension, coronary heart disease, obesity, metabolic syndrome, inflammatory bowel diseases, etc. The aim of current pharmacotherapy for PsA is to achieve remission or minimal activity of clinical manifestations of the disease, to delay or prevent its X-ray progression, to increase survival, to improve quality of life in patients, and to reduce the risk of comorbidities. The paper considers groups of medicines used to treat the disease, among other issues, information about biological agents (BA registered in the Russian Federation for the treatment of PsA. Most patients are mentioned to show a good response to this therapy option just 3–6 months after treatment initiation; however, some of them develop primary inefficiency. In this case, switching one BA to another is recommended. Some patients using a BA develop secondary treatment inefficiency, which is firstly due to the appearance of

    Traumatic Brain Injury (TBI) affects a large proportion and extensive array of individuals in the population. While precise pathological mechanisms are lacking, the growing base of knowledge concerning TBI has put increased emphasis on its understanding and treatment. Most treatments of TBI are aimed at ameliorating secondary insults arising from the injury; these insults can be characterized with respect to time post-injury, including early, intermediate, and late pathological changes. Early pathological responses are due to energy depletion and cell death secondary to excitotoxicity, the intermediate phase is characterized by neuroinflammation and the late stage by increased susceptibility to seizures and epilepsy. Current treatments of TBI have been tailored to these distinct pathological stages with some overlap. Many prophylactic, pharmacologic, and surgical treatments are used post-TBI to halt the progression of these pathologic reactions. In the present review, we discuss the mechanisms of the pathological hallmarks of TBI and both current and novel treatments which target the respective pathways. PMID:24381049

    The periodontal abscess is an acute destructive process in the periodontium resulting in localized collections of pus communicating with the oral cavity through the gingival sulcus or other periodontal sites and not arising from the tooth pulp. The prevalence of periodontal abscess is relatively high and it affects the prognosis of the tooth. Periodontal abscesses can develop on the base of persisting periodontitis but can also occur in the absence of periodontitis. The cause of the development of periodontal abscess originating from chronic periodontitis is the marginal closure of a periodontal pocket, or the pocket lumen might be too tight to drain the increased suppuration due to changes in the composition of subgingival microflora, alteration of bacterial virulence or host defenses. Diagnosis of a periodontal abscess is based on medical and dental history as well as oral examination (pocket depth, swelling, suppuration, mobility, sensibility of the tooth). The most prevalent group of bacteria: P. gingivalis, P. intermedia, B. forsythus, F. nucleatum and P. micros. Previous studies have suggested that the complete therapy of the periodontitis patients with acute periodontal abscess has to do in two stages: the first stage is the management of acute lesions, then the second stage is the appropriate comprehensive treatment of the original and/or residual lesions. The management of acute lesions includes establishing drainage via pocket lumen, subgingival scaling and root planing, curettage of the lining pocket epithelia and seriously inflamed connective tissue, compressing pocket wall to underlying tooth and periodontal support, and maintaining tissue contact. Some authors recommend the incision or to establish drainage and irrigation, or a flap surgery, or even extraction of hopeless teeth. We recommend the use of systemic antibiotics as a preventive measure of systemic disease or in case of systemic symptoms.

    Chronic fatigue syndrome is characterised by intense fatigue, with duration of over six months and associated to other related symptoms. The latter include asthenia and easily induced tiredness that is not recovered after a night's sleep. The fatigue becomes so severe that it forces a 50% reduction in daily activities. Given its unknown aetiology, different hypotheses have been considered to explain the origin of the condition (from immunological disorders to the presence of post-traumatic oxidative stress), although there are no conclusive diagnostic tests. Diagnosis is established through the exclusion of other diseases causing fatigue. This syndrome is rare in childhood and adolescence, although the fatigue symptom per se is quite common in paediatric patients. Currently, no curative treatment exists for patients with chronic fatigue syndrome. The therapeutic approach to this syndrome requires a combination of different therapeutic modalities. The specific characteristics of the symptomatology of patients with chronic fatigue require a rapid adaptation of the educational, healthcare and social systems to prevent the problems derived from current systems. Such patients require multidisciplinary management due to the multiple and different issues affecting them. This document was realized by one of the Interdisciplinary Work Groups from the Institute for Rare Diseases, and its aim is to point out the main social and care needs for people affected with Chronic Fatigue Syndrome. For this, it includes not only the view of representatives for different scientific societies, but also the patient associations view, because they know the true history of their social and sanitary needs. In an interdisciplinary approach, this work also reviews the principal scientific, medical, socio-sanitary and psychological aspects of Chronic Fatigue Syndrome. PMID:19857242

    The abdominal sacrocolpopexy is an excellent procedure to surgically treat vaginal vault prolapse. A synthetic graft is often used to support the vaginal apex, but has the potential to become infected or erode, requiring its removal or revision. The purpose of this paper is to report our experience in the management of patients with infected synthetic grafts after abdominal sacrocolpopexy. A review of the patient databases from three specialty gynecology centers was performed from March 1996 to June 2002. Only patients with an infected graft after an abdominal sacrocolpopexy were included in the study; patients with either suture or graft erosion responding to conservative treatment were excluded. Twenty-two women, ages 37-73 years, developed infection of the synthetic graft after an abdominal sacrocolpopexy (1-60 months after their initial surgery, mean 8.8 months). The infected materials included polytetrafluoroethylene (PTFE, Goretex, n =15) and polypropylene (n=7). Nine of the 15 PTFE meshes and four of the seven polypropylene meshes were placed at the time of a contaminated case (abdominal hysterectomy [n=12], colon resection [n=1]). Eighteen (82%) of the infected grafts involved braided permanent suture to attach the graft to the vaginal wall, monofilament/non-braided permanent suture was used in three patients, and suture type could not be determined in one. All graft removals were attempted vaginally, and this was successful in 16 cases (73%). Two patients experienced significant bleeding: the first patient required an emergency laparotomy and the second patient's bleeding was controlled with packing. A rectovaginal fistula occurred 3 weeks postoperatively in one patient. Synthetic graft infection should be considered as the differential diagnosis in a patient who has undergone an abdominal sacrocolpopexy. Transvaginal removal is preferred, but is fraught with potentially serious complications. The use of braided permanent sutures to affix the graft to the

    There is a range of therapies to treat Post Traumatic Stress Disorder (PTSD) but treatment resistance remains high, with many sufferers experiencing the chronic condition. Engagement in trauma-focused psychotherapy is difficult for some patients with PTSD, especially those with extreme affect dysregulation associated with recall of traumatic memories. In recent years there have been a number of neuroscientific and clinical studies examining the potential role for adjunctive drug-assisted psychotherapy using 3,4,-methylenedioxmethamphetamine (MDMA) as a treatment for PTSD. re-visiting of a novel approach to trauma-focused psychotherapy with Used just two or three times, under careful medical supervision and specialised psychotherapy support MDMA appears to facilitate the recall of traumatic memories without the user feeling overwhelmed by the negative affect that usually accompanies such memories. This therapeutic approach began in the 1980s and was subsequently shelved in the midst of public health concerns surrounding the recreational use of the drug ecstasy. When pharmaceutical grade MDMA is used in a clinical setting it does not share the same risk profiles as ecstasy. Recent phase one neurophysiological studies and phase two clinical studies are showing promise as a potential new approach to managing treatment-resistant PTSD. Crown Copyright © 2016.

    2013-01-01

    Full Text Available Tyrosine kinase inhibitors (TKI belong to a new class of molecular multitargeted anticancer therapy which targets different growth factor receptors and hence attenuates cancer cell survival and growth. Since their introduction as adjunct treatment for renal cell carcinoma and gastrointestinal stromal tumors (GIST, a number of reports have demonstrated that TKI can induce thyroid dysfunction which was especially more common with sunitinib maleate. Many mechanisms with respect to this adverse effect of tyrosine kinase inhibitors have been proposed including their induction of thyroiditis, capillary regression in the thyroid gland, antithyroid peroxidase antibody production, and their ability to decrease iodine uptake by the thyroid gland. Of interest is the observation that TKI-induced thyroid dysfunction may actually be protective as it was shown to improve overall survival, and it was suggested that it may have a prognostic value. Followup on thyroid function tests while patients are maintained on tyrosine kinase inhibitor is strongly recommended. When thyroid dysfunction occurs, appropriate treatment should be individualized depending on patients symptoms and thyroid stimulating hormone level.

    Post-pregnancy osteoporosis is a rare condition with little known pathophysiology. Most cases are diagnosed in the late stage of pregnancy or in the post-partum while breastfeeding, particularly in first pregnancy. Vertebral fractures are most commonly observed and characterized by prolonged severe pain and functional limitations. Measurements of bone mineral density(BMD)of the lumbar spine and proximal femur with dual energy X-ray absorptiometry(DXA)are the clinical methods most commonly used for no fracture women. Conventional radiography will confirm the fracture in most cases, and magnetic resonance(MR), which can be safely used during pregnancy, is effective in detecting vertebral fractures and bone marrow edema. Although the bone resorption increased at the end of pregnancy and lactation, the bone formation increases and the bone structure is almost recovered after cessation of lactating in postpartum. There is much uncertainty about whether pharmacological treatments should be used for osteoporosis that presents during pregnancy and lactation. This is partly because of the lack of a firm evidence base for treatment and also because there is a spontaneous recovery of bone mass and strength after pregnancy or weaning.

    The pancreas and salivary glands have similar anatomical structures and physiological functions producing bicarbonate-rich fluid containing digestive enzymes and other components to be delivered into the gut. Despite these similarities, the two organs are also different in numerous respects, especially regarding the inflammatory diseases affecting them. This article will summarize the pathophysiology and current and potential pharmacological treatments of chronic inflammatory diseases such as chronic pancreatitis, autoimmune pancreatitis, Sjögren's syndrome and irradiation-induced salivary gland atrophy. Despite the differences, in both organs the inflammatory process is accompanied by epithelial tissue destruction and fibrosis. Both in pancreatic and in salivary research, an important task is to stop or even reverse this process. The utilization of stem/progenitor cell populations previously identified in these organs and the application of mesenchymal stem cells are very promising for such regenerative purposes. In addition, gene therapy and tissue engineering research progressively advance and have already yielded clinically beneficial preliminary results for salivary gland diseases. For the hard-to-access, hard-to-regenerate pancreas these developments may also offer new solutions, especially since salivary and pancreatic progenitors are very similar in characteristics and may be mutually useful to regenerate the respective other organ as well. These novel developments could be of great significance and may bring new hope for patients since currently used therapeutic protocols in salivary and in pancreatic chronic inflammatory diseases offer primarily symptomatic treatments and limited beneficial outcome.

    Symptoms related to functional and sensory abnormalities are frequently encountered in patients with diabetes mellitus. Most symptoms are associated with impaired gastric and intestinal function. In this review, we discuss basic concepts of sensory-motor dysfunction and how they relate to clinical findings and gastrointestinal abnormalities that are commonly seen in diabetes. In addition, we review techniques that are available for investigating the autonomic nervous system, neuroimaging and neurophysiology of sensory-motor function. Such technological advances, while not readily available in the clinical setting, may facilitate stratification and individualization of therapy in diabetic patients in the future. Unraveling the structural, mechanical, and sensory remodeling in diabetes disease is based on a multidisciplinary approach that can bridge the knowledge from a variety of scientific disciplines. The final goal is to increase the understanding of the damage to GI structures and to sensory processing of symptoms, in order to assist clinicians with developing an optimal mechanics based treatment.

  15. Role of pathophysiology of patellofemoral instability in the treatment of spontaneous medial patellofemoral subluxation: a case report

    Full Text Available Abstract Introduction Medial patellar subluxation is usually seen after lateral retinacular release. Spontaneous medial subluxation of the patella is a very rare condition. There are few reports in the literature on the pathophysiology of iatrogenic medial patellar subluxation. To our knowledge, there are no reports of the pathophysiology of non-iatrogenic medial patellar subluxation in the English literature. In this study we present a case of spontaneous medial patellar instability that is more prominent in extension during weight bearing. We also try to define the treatment protocol based on pathophsiology. Case presentation We report the case of a 21-year-old Turkish man with spontaneous medial patellar instability. He had suffered right knee pain, clicking and popping sensation in the affected knee for three months prior to presentation. Clinical examination demonstrated medial patellar subluxation that is more prominent in extension during the weight bearing phase of gait and while standing. Increased medial tilt was observed when the patella was stressed medially. Conventional anterior to posterior, lateral and Merchant radiographs did not reveal any abnormalities. After three months of physical therapy, our patient was still suffering from right knee pain which disturbed his gait pattern. Throughout the surgery, medial patellar translation was tested following the imbrication of lateral structures. He still had a medial patellar translation that was more than 50% of his patellar width. Patellotibial ligament augmentation using an iliotibial band flap was added. When examined after surgery, the alignment of the patella was effectively corrected. Conclusions Chronic imbalance between the strengths of vastus lateralis and vastus medialis results in secondary changes in passive ligamentous structures and causes additional instability. Physical therapy modalities that aim to strengthen the vastus lateralis might be sufficient for the

    Improvements in the control of haemorrhage after trauma have resulted in the survival of many people who would otherwise have died from the initial loss of blood. However, the danger is not over once bleeding has been arrested and blood pressure restored. Two-thirds of patients who die following major trauma now do so as a result of causes other than exsanguination. Trauma evokes a systemic reaction that includes an acute, non-specific, immune response associated, paradoxically, with reduced resistance to infection. The result is damage to multiple organs caused by the initial cascade of inflammation aggravated by subsequent sepsis to which the body has become susceptible. This Series examines the biological mechanisms and clinical implications of the cascade of events caused by large-scale trauma that leads to multiorgan failure and death, despite the stemming of blood loss. Furthermore, the stark and robust epidemiological finding--namely, that age has a profound influence on the chances of surviving trauma irrespective of the nature and severity of the injury--will be explored. Advances in our understanding of the inflammatory response to trauma, the impact of ageing on this response, and how this information has led to new and emerging treatments aimed at combating immune dysregulation and reduced immunity after injury will also be discussed.

    Immunodeficient mice that lack all lymphocyte subsets and have phagocytic cells that are tolerant of human cells can be stably xenografted with human hematopoietic stem cell as well as other human tissues (fetal liver and thymus) creating 'human immune system' (HIS) mice. HIS mice develop all major human lymphocyte classes (B, T, natural killer, and innate lymphoid cell) and their specialized subsets as well as a variety of myeloid cells (dendritic cell, monocytes, and macrophages) thereby providing a small animal model in which to interrogate human immune responses to infection. HIS mouse models have been successfully used to study several aspects of HIV-1 biology, including viral life cycle (entry, restriction, replication, and spread) as well as virus-induced immunopathology (CD4 T-cell depletion, immune activation, and mucosal inflammation). Recent work has shown that HIV reservoirs can be established in HIV-infected HIS mice after treatment with combinations of antiretroviral drugs thereby providing a model to test new approaches to eliminate latently infected cells. HIS mice provide cost-effective preclinical platform to assess combination immunotherapies that can target HIV reservoirs. Therapeutic strategies validated in HIS mice should be considered in designing the roadmap toward HIV 'cure'.

    2017-05-01

    Full Text Available Yearly more than 15 million babies are born premature (<37 weeks gestational age, accounting for more than 1 in 10 births worldwide. Lung injury caused by maternal chorioamnionitis or preeclampsia, postnatal ventilation, hyperoxia, or inflammation can lead to the development of bronchopulmonary dysplasia (BPD, one of the most common adverse outcomes in these preterm neonates. BPD patients have an arrest in alveolar and microvascular development and more frequently develop asthma and early-onset emphysema as they age. Understanding how the alveoli develop, and repair, and regenerate after injury is critical for the development of therapies, as unfortunately there is still no cure for BPD. In this review, we aim to provide an overview of emerging new concepts in the understanding of perinatal lung development and injury from a molecular and cellular point of view and how this is paving the way for new therapeutic options to prevent or treat BPD, as well as a reflection on current treatment procedures.

    Alzheimer's disease is often diagnosed too late. Its etiology is still largely unknown and remains one of the big challenges in neurobiological fundamental research. Optimized early and differential diagnosis can be ensured by a dynamic concept of multidisciplinary diagnosis in cooperation between practitioners specializing in brain disorders, clinical psychogeriatric deprtments, and general practitioners. This, in turn, will enable individualized planning of further living conditions and care of Alzheimer patients and their relations as well as efficient and early pharmacotherapy and psychological intervention.

    Full Text Available Nicholas Ah Mew, Ljubica CaldovicCenter for Genetic Medicine Research, Children’s Research Institute, Children’s National Medical Center, Washington DC, USAAbstract: The conversion of ammonia into urea by the human liver requires the coordinated function of the 6 enzymes and 2 transporters of the urea cycle. The initial and rate-limiting enzyme of the urea cycle, carbamylphosphate synthetase 1 (CPS1, requires an allosteric activator, N-acetylglutamate (NAG. The formation of this unique cofactor from glutamate and acetyl Coenzyme-A is catalyzed by N-acetylglutamate synthase (NAGS. An absence of NAG as a consequence of NAGS deficiency may compromise flux through CPS1 and result in hyperammonemia. The NAGS gene encodes a 528-amino acid protein, consisting of a C-terminal catalytic domain, a variable segment, and an N-terminal mitochondrial targeting signal. Only 22 mutations in the NAGS gene have been reported to date, mostly in the catalytic domain. NAGS is primarily expressed in the liver and intestine. However, it is also surprisingly expressed in testis, stomach and spleen, and during early embryonic development at levels not concordant with the expression of other urea cycle enzymes, CPS1, or ornithine transcarbamylase. The purpose of NAGS expression in these tissues, and its significance to NAGS deficiency is as yet unknown. Inherited NAGS deficiency is the rarest of the urea cycle disorders, and we review the currently reported 34 cases. Treatment of NAGS deficiency with N-carbamyglutamate, a stable analog of NAG, can restore deficient urea cycle function and normalize blood ammonia in affected patients.Keywords: urea cycle, urea cycle disorder, N-acetyl-L-glutamate, N-acetylglutamate synthase, hyperammonemia, N-carbamyl-L-glutamate

    Stress, which is defined as an acute threat to homeostasis, shows both short- and long-term effects on the functions of the gastrointestinal tract. Exposure to stress results in alterations of the brain-gut interactions ("brain-gut axis") ultimately leading to the development of a broad array of gastrointestinal disorders including inflammatory bowel disease (IBD), irritable bowel syndrome (IBS) and other functional gastrointestinal diseases, food antigen-related adverse responses, peptic ulcer and gastroesophageal reflux disease (GERD). The major effects of stress on gut physiology include: 1) alterations in gastrointestinal motility; 2) increase in visceral perception; 3) changes in gastrointestinal secretion; 4) increase in intestinal permeability; 5) negative effects on regenerative capacity of gastrointestinal mucosa and mucosal blood flow; and 6) negative effects on intestinal microbiota. Mast cells (MC) are important effectors of brain-gut axis that translate the stress signals into the release of a wide range of neurotransmitters and proinflammatory cytokines, which may profoundly affect the gastrointestinal physiology. IBS represents the most important gastrointestinal disorder in humans, and is characterized by chronic or recurrent pain associated with altered bowel motility. The diagnostic testing for IBS patients include routine blood tests, stool tests, celiac disease serology, abdominal sonography, breath testing to rule out carbohydrate (lactose, fructose, etc.) intolerance and small intestinal bacterial overgrowth. Colonoscopy is recommended if alarming symptoms are present or to obtain colonic biopsies especially in patients with diarrhoea predominant IBS. The management of IBS is based on a multifactorial approach and includes pharmacotherapy targeted against the predominant symptom, behavioural and psychological treatment, dietary alterations, education, reassurance and effective patient-physician relationship.

    Acute pancreatitis is a fascinating disease. In the United States, the two most common etiologies of acute pancreatitis are gallstones and excessive alcohol consumption. The diagnosis of acute pancreatitis is made with a combination of history, physical examination, computed tomography scan, and laboratory evaluation. Differentiating patients who will have a benign course of their pancreatitis from patients who will have severe pancreatitis is challenging to the clinician. C-reactive protein, pro-calcitonin, and the Bedside Index for Severity of Acute Pancreatitis appeared to be the best tools for the early and accurate diagnosis of severe pancreatitis. Early laparoscopic cholecystectomy is indicated for patients with mild gallstone pancreatitis. For patients who are going to have a prolonged hospitalization, enteral nutrition is preferred. Total parenteral nutrition should be reserved for patients who cannot tolerate enteral nutrition. Prophylactic antibiotics are not indicated for patients with pancreatic necrosis. Surgical intervention for infected pancreatic necrosis should be delayed as long as possible to improve patient outcomes.

    This thesis is concerned with a single diagnostic technique: the bitewing radiograph, and the way it is used by dentists to decide on patient treatment need for interproximal caries. The variation in caries diagnosis and treatment decisions using bitewing radiographs is described and the radiographic criteria of choice for minimizing over and undertreatment according to a norm are investigated. Three possible diagnostic strategies in interproximal caries diagnosis using a decision analysis approach are described and evaluated, and the effect of the reported diagnostic behaviour and knowledge of practicing Dutch dentists in their use of bitewing radiographs for the diagnosis and treatment of interproximal caries is described and analyzed.

    Pneumothorax is an urgent situation that has to be treated immediately upon diagnosis. Pneumothorax is divided to primary and secondary. A primary pneumothorax is considered the one that occurs without an apparent cause and in the absence of significant lung disease. On the other hand secondary pneumothorax occurs in the presence of existing lung pathology. There is the case where an amount of air in the chest increases markedly and a one-way valve is formed leading to a tension pneumothorax....

    Rheumatoid arthritis (RA) is an inflammatory progressive disease which in the absence of appropriate treatment can lead to joint destruction and disability. Prognosis of RA may be predicted based on the presence of some clinical and laboratory evidences. New criteria for classification of RA provide opportunity for earlier treatment. Initiation of treatment particularly by combination of DMARDs concurrent with short duration of corticosteroid is expected to prevent progressive course and even change the natural course of RA. At present any patients with clinical synovitis in at least one joint may have definite RA, requiring agressive treatment.

    Anorectal disorders affect men and women of all ages. Their management is not limited to the evaluation and treatment of hemorrhoids. Rather, a spectrum of anorectal disorders ranges from benign and irritating (pruritus ani) to potentially life-threatening (anorectal cancer). Symptoms are nonspecific, which can make the evaluation of patients difficult. In addition, treatment can be frustrating because clinicians are hamstrung by a lack of well-designed, prospective, clinical trials. Some of the most common anorectal disorders include fecal incontinence, pelvic floor dyssynergia, anal fissures, pruritus ani, proctalgia fugax, and solitary rectal ulcer syndrome. This article provides an update on the evaluation and treatment of common anorectal disorders.

    To review what is understood about the pathophysiology of polycystic ovarian syndrome (PCOS), the diagnostic challenges of PCOS in adolescent women, associated risk factors, as well as the best evidence-based treatment options for adolescence. Diagnosing PCOS in adolescents requires a unique set of criteria for which no single marker currently exists. Adolescents at high risk for developing the syndrome are congenital virilization, low birth weight, premature pubarche, central precocious puberty, large for gestational age girls born to overweight mothers, obesity syndromes, insulin-resistant features, and girls born to parents with PCOS, central obesity, or diabetes in whom PCOS ought to be suspected when associated with irregular menses. Insulin, hyperandrogenemia, and adipocytokines are integral players in the pathophysiology of PCOS. PCOS may be an inheritable trait; however, no gene has yet been identified. Quality of life remains a concern for young women with PCOS. Lifestyle modifications geared to prevent long-term sequelae remain the first-line treatment in conjunction with oral contraceptive pills. Identifying PCOS in adolescents remains a diagnostic dilemma, but early intervention and treatment can improve long-term health.

    2015-03-15

    Temporomandibular disorders (TMD) are a heterogeneous group of musculoskeletal and neuromuscular conditions involving the temporomandibular joint complex, and surrounding musculature and osseous components. TMD affects up to 15% of adults, with a peak incidence at 20 to 40 years of age. TMD is classified as intra-articular or extra-articular. Common symptoms include jaw pain or dysfunction, earache, headache, and facial pain. The etiology of TMD is multifactorial and includes biologic, environmental, social, emotional, and cognitive triggers. Diagnosis is most often based on history and physical examination. Diagnostic imaging may be beneficial when malocclusion or intra-articular abnormalities are suspected. Most patients improve with a combination of noninvasive therapies, including patient education, self-care, cognitive behavior therapy, pharmacotherapy, physical therapy, and occlusal devices. Nonsteroidal anti-inflammatory drugs and muscle relaxants are recommended initially, and benzodiazepines or antidepressants may be added for chronic cases. Referral to an oral and maxillofacial surgeon is indicated for refractory cases.

    Full Text Available Enteropathic arthritis (EA is a spondyloarthritis (SpA which occurs in patients with inflammatory bowel diseases (IBDs and other gastrointestinal diseases. Diagnosis is generally established on the medical history and physical examination. It was, generally, made according to the European Spondyloarthropathy Study Group (ESSG criteria. Rheumatic manifestations are the most frequent extraintestinal findings of IBD with a prevalence between 17% and 39%, and IBD is associated, less frequently, with other rheumatic disease such as rheumatoid arthritis, Sjogren syndrome, Takayasu arteritis, and fibromyalgia. Although the pathogenesis of EA has not been plainly clarified, the most popular theory supposes that joint inflammation occurs in genetically predisposed subjects with bacterial gut infections, provided an important evidence for a possible relationship between inflammation of the gut mucosa and arthritis. The management of patients with EA requires an active cooperation between the gastroenterologist and rheumatologist.

    2017-02-07

    Given the high comorbidity in patients on hemodialysis and the complexity of the dialysis treatment, it is remarkable how rarely a life-threatening complication occurs during dialysis. The low rate of dialysis emergencies can be attributed to numerous safety features in modern dialysis machines; meticulous treatment and testing of the dialysate solution to prevent exposure to trace elements, toxins, and pathogens; adherence to detailed treatment protocols; and extensive training of dialysis staff to handle medical emergencies. Most hemodialysis emergencies can be attributed to human error. A smaller number are due to rare idiosyncratic reactions. In this review, we highlight major emergencies that may occur during hemodialysis treatments, describe their pathogenesis, offer measures to minimize them, and provide specific interventions to prevent catastrophic consequences on the rare occasions when such emergencies arise. These emergencies include dialysis disequilibrium syndrome, venous air embolism, hemolysis, venous needle dislodgement, vascular access hemorrhage, major allergic reactions to the dialyzer or treatment medications, and disruption or contamination of the dialysis water system. Finally, we describe root cause analysis after a dialysis emergency has occurred to prevent a future recurrence. Copyright © 2017 by the American Society of Nephrology.

    2017-10-01

    Patients with cancer frequently experience unintended weight loss due to gastrointestinal (GI) dysfunction caused by the malignancy or treatment of the malignancy. However, others may present with weight loss related to other symptoms not clearly associated with identifiable GI dysfunction such as anorexia and early satiety. Cancer cachexia (CC) is a multifactorial syndrome that is generally characterized by ongoing loss of skeletal muscle mass with or without fat loss, often accompanied by anorexia, weakness, and fatigue. CC is associated with poor tolerance of antitumor treatments, reduced quality of life (QOL), and negative impact on survival. Symptoms associated with CC are thought to be caused in part by tumor-induced changes in host metabolism that result in systemic inflammation and abnormal neurohormonal responses. Unfortunately, there is no single standard treatment for CC. Nutrition consequences of oncologic treatments should be identified early with nutrition screening and assessment. Pharmacologic agents directed at improving appetite and countering metabolic abnormalities that cause inefficient nutrient utilization are currently the foundation for treating CC. Multiple agents have been investigated for their effects on weight, muscle wasting, and QOL. However, few are commercially available for use. Considerations for choosing the most appropriate treatment include effect on appetite, weight, QOL, risk of adverse effects, and cost and availability of the agent.

    Esophageal achalasia is a primary esophageal motility disorder of unknown origin, characterized by lack of peristalsis and by incomplete or absent relaxation of the lower esophageal sphincter in response to swallowing. The goal of treatment is to eliminate the functional obstruction at the level of the gastroesophageal junction Areas covered: This comprehensive review will evaluate the current literature, illustrating the diagnostic evaluation and providing an evidence-based treatment algorithm for this disease Expert commentary: Today we have three very effective therapeutic modalities to treat patients with achalasia - pneumatic dilatation, per-oral endoscopic myotomy and laparoscopic Heller myotomy with fundoplication. Treatment should be tailored to the individual patient, in centers where a multidisciplinary approach is available. Esophageal resection should be considered as a last resort for patients who have failed prior therapeutic attempts.

    Comorbidity between substance use disorders (SUD) and major depression (MD) is the most common dual pathology in the field of addiction to substances and has prevalence rates ranging between 12% and 80%, which complicates the response to treatment and worsens the prognosis of patients. Differentiating between diagnoses of induced depressive episodes and primary depressive episodes concurrent to substance use is especially relevant for therapeutic management. This article presents the state of the art of the currently available pharmacologic treatments of comorbid depression in patients with SUD, taking into account the safety and risk of abuse of antidepressant drugs. Due to the fact that comorbidity of MD and SUD is frequent and presents greater psychopathological and medical severity, as well as worse social functioning, it is crucial to treat MD and SUD simultaneously using the integrated treatment model and not to treat both conditions separately.

    Mozart ear is a congenital auricular deformity, which is mainly characterized by a bulging appearance of the anterosuperior portion of the auricle, a convexly protruded cavum conchae, and a slit-like narrowing of the orifice of the external auditory meatus. It is said to be uncommon, and because no one has yet fully described neither the disease nor the treatment, the concept of Mozart ear has not been unified. This report describes a case of a 13-year-old girl presented with an unusual congenital deformity which showed the features of Mozart ear. It is an extremely rare deformity that only about 4 clinical cases have been reported in medical literature thereby a treatment method has not been fully discussed. For surgical correction of our cases, we excised deformed conchal cartilage, turned it over, regrafted, and maintained a cosmetically positive result. We also reviewed and described the origin, current concept, and treatment method of Mozart ear.

    Peripheral neuropathy is a prevalent condition that usually warrants a thorough history and examination but has limited diagnostic evaluation. However, rare localizations of peripheral neuropathy often require more extensive diagnostic testing and different treatments. To describe rare localizations of peripheral neuropathy, including the appropriate diagnostic evaluation and available treatments. References were identified from PubMed searches conducted on May 29, 2015, with an emphasis on systematic reviews and randomized clinical trials. Articles were also identified through the use of the authors' own files. Search terms included common rare neuropathy localizations and their causes, as well as epidemiology, pathophysiology, diagnosis, and treatment. Diffuse, nonlength-dependent neuropathies, multiple mononeuropathies, polyradiculopathies, plexopathies, and radiculoplexus neuropathies are rare peripheral neuropathy localizations that often require extensive diagnostic testing. Atypical neuropathy features, such as acute/subacute onset, asymmetry, and/or motor predominant signs, are frequently present. The most common diffuse, nonlength-dependent neuropathies are Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy, and amyotrophic lateral sclerosis. Effective disease-modifying therapies exist for many diffuse, nonlength-dependent neuropathies including Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy, and some paraprotein-associated demyelinating neuropathies. Vasculitic neuropathy (multiple mononeuropathy) also has efficacious treatment options, but definitive evidence of a treatment effect for IgM anti-MAG neuropathy and diabetic amyotrophy (radiculoplexus neuropathy) is lacking. Recognition of rare localizations of peripheral neuropathy is essential given the implications for diagnostic testing and treatment. Electrodiagnostic studies are an important

    The increasing prevalence of diabetes is a major health problem. The detection and treatment of prediabetes can delay the onset of diabetes and presents an important diabetes prevention strategy. Using data from the 2012 National Ambulatory Medical Care Survey, we studied visits by adults aged ≥45 years without diagnosed diabetes who had an HbA1c test within 90 days of the visit (n = 518 unweighted visits; n = 11,167,004 weighted visits). HbA1c results were categorized into normal, prediabetes, and diabetes, and we examined patient characteristics (age, sex, race, payer type, body mass index) and treatment of prediabetes. Among visiting adults, 54.6% had a normal HbA1c value, 33.6% had prediabetes, and 11.9% had diabetes. Of those patient visits with HbA1c consistent with prediabetes, the number of patients diagnosed with prediabetes was too low for a reliable population estimate. Indication of treatment in the medical record (lifestyle modification counseling and/or metformin) was present in 23.0% of those with diagnosed or undiagnosed prediabetes. The most common treatment was lifestyle modification counseling. Our findings show that there are missed opportunities for diabetes prevention in primary care. Providers need to change their approach to prediabetes and play a more effective role in preventing diabetes. © Copyright 2016 by the American Board of Family Medicine.

  9. Diagnosis and treatment of Ewing's sarcoma

    International Nuclear Information System (INIS)

    Iwamoto, Yukihide

    2007-01-01

    Ewing's sarcoma is a small round-cell tumor typically arising in the bones, rarely in soft tissues, of children and adolescents. Ewing's sarcoma has retained the most unfavorable prognosis of all primary musculoskeletal tumors. Prior to the use of multi-drug chemotherapy, long-term survival was less than 10%. The development of multi-disciplinary therapy with chemotherapy, irradiation, and surgery has increased current long-term survival rates in most clinical centers to greater than 50%. In addition, the preferred method of tumor resection has changed; limb salvage has nearly replaced amputation of the affected limb. Limb salvage procedures can be performed in place of amputation without compromising patient survival rates. Recent studies have revealed that the pathognomonic translocations involving the EWS gene on chromosome 22 and an ETS-type gene, which is most commonly the Fli1 gene on chromosome 11, are implicated in more than 95% of Ewing's sarcomas, primitive neuroectodermal tumors and Askin's tumors. Therefore, these lesions have become regarded as a single entity, dubbed the Ewing's family of tumors. Reverse transcription polymerase chain reaction (RT-PCR) to detect EWS-ETS gene arrangements is widely used to confirm the diagnosis of Ewing's family of tumors. Experimental results suggest that inhibition of the signaling pathway downstream of the EWS-ETS gene may lead to the development of molecularly targeted therapy in the future. (author)

  10. Intranasal tumors in dogs: diagnosis and treatment

    International Nuclear Information System (INIS)

    1996-01-01

    Intranasal tumors are rare in dogs and occur mostly in middle-aged and old dogs. The malignant behavior of these tumors is reflected more by their tendency to invade local tissue than by a tendency to produce distant metastasis. Distant metastasis may, however, become more important as success in treatment of the initial lesion improves. The history and clinical signs (sneezing, nasal discharge, and facial deformity) of intranasal tumor in dogs often reflect intranasal disease but are usually nonspecific. Diagnostics should include at least the minimum data base, high-detail radiographs of the nasal cavity obtained while the dog is anesthetized, and biopsy of nasal cavity tissue. Radiotherapy with or without aggressive cytoreduction is the only treatment that significantly extends survival of these dogs. Ortho-voltage, megavoltage, or brachytherapy (implantation of (192)lridium) has been used

  11. [Subclinical hyperthyroidism: from diagnosis to treatment].

    Corvilain, B

    2012-09-01

    Subclinical hyperthyroidism is a common clinical entity. Subclinical hyperthyroidism is defined as a serum TSH below the reference range but a normal T4 and T3 level in an asymptomatic patient. Whether or not subclinical hyperthyroidism should be treated remains a matter of debate. Cross-sectional studies and longitudinal population-based studies demonstrate association between subclinical hyperthyroidism and risk of atrial fibrillation, osteoporosis and cardiovascular and global mortality. However, there are no randomized clinical trials answering the question whether long term-health outcomes are improved by the treatment of subclinical hyperthyroidism. Therefore in the absence of evidence for or against treatment of subclinical hyperthyroidism, it seems appropriate to follow algorithms that consider the level of TSH and the presence of risks factors (age > 65 years, osteoporosis, post menopause and cardiac disease).

    Pituitary tumors cause symptoms by secreting hormones (prolactin, PRL, responsible for amenorrhea-galactorrhea in women and decreased libido in men; growth hormone, GH, responsible for acromegaly; adrenocorticotropic hormone, ACTH, responsible for Cushing's syndrome; thyroid-stimulating hormone, TSH, responsible for hyperthyroidism), depressing the secretion of hormones (hypopituitarism), or by mass-related effects (headaches, visual field abnormalities...). All patients with pituitary tumors should be evaluated for gonadal, thyroid and adrenal function as well as PRL and GH secretion. Specific stimulation and suppression tests for pituitary hormones are performed in selected situations for detecting the type of hypersecretion or the response to treatment. Imaging procedures (mainly magnetic resonance imaging, MRI, nowadays) determine the presence, size and extent of the lesion. The classification of pituitary tumors is based on the staining properties of the cell cytoplasm viewed by light microscopy and immunocytochemistry revealing the secretory pattern of the adenoma. Treatment of pituitary adenomas consists of surgery (performed in more than 99% of cases via a transphenoidal route) and radiotherapy, generally fractionated or, in selected cases, using stereotactic techniques such as gamma-knife. The availability of medical treatment (dopamine, DA, agonists, somatostatin analogs, GH-receptor antagonists...) has profoundly modified the indications of radiotherapy, drugs being now generally used as a second-line treatment, after surgery (or even as first-line treatment). Based on the results of the different treatment modalities for each type of pituitary adenoma, recommendations will be proposed. They may be summarized as follows. For treatment of GH-secreting adenomas, trans-sphenoidal surgery is the first-line therapy except when the macroadenoma is giant or if surgery is contra-indicated; postoperative radiation therapy (fractionated, or by gamma-knife) is

    2014-12-01

    Chiari malformations refer to abnormalities of the hindbrain originally described by the Austrian pathologist Hans Chiari in the early 1890s. These malformations range from herniation of the cerebellar tonsils through the foramen magnum to complete agenesis of the cerebellum. In this review, we review the different classification schemes of Chiari malformations. We discuss the different signs and symptoms that the two most common malformations present with and diagnostic criteria. We next discuss current treatment paradigms, including the new measure of possible in utero surgery to help decrease the incidence of Chiari type II malformations. There is also a small discussion of treatment failures and salvage procedures in these difficult cases. Chiari malformations are a difficult clinical entity to treat. As more is learned about the genetic and environmental factors relating to their characteristics, it will be interesting if we are able to predict which treatments are better suited for different patients. Similarly, with the evolution of in utero techniques especially for Chiari II malformations, it will be interesting to see if the incidence and practice of treating these difficult patients will change.

    To investigate the factors associated with patients with Fournier's gangrene, and to clarify the effect of diabetes mellitus (DM) as a comorbid disease on morbidity and mortality of patients with Fournier's gangrene. Twenty-six Fournier's gangrene patients who were admitted to the Emergency Department of Ankara Numune Teaching and Research Hospital, Ankara, Turkey from 1997 to 2003 were examined retrospectively. The mean age of the patients was 52.8 years. There were 8 female (30.8%) and 18 male (69.2%) patients. The etiological causes were as follows: diseases of the perianal region, history of operations, trauma and injections. Major comorbid disease states were diabetes mellitus (DM) and hypertension. The lesions in Fournier's gangrene were most commonly located in the perineum and genital region. Female patients with diabetes mellitus had significantly unusual extensive involvement, especially abdominal wall involvement. The most frequently isolated pathogen was Escherichia coli, while staphylococcal infection was most commonly seen in the presence of DM. Colostomy was performed on 53.8% of the patients, and cystostomy on 7.6% of the patients. Average time of staying at the hospital was 25 days with a mortality rate of 34.6%. Patients with DM had high mortality rates and stayed longer at the hospital than the non-diabetic patients. In addition to early diagnosis, early and aggressive debridement and administration of multiple wide spectrum antibiotics chosen for the causative agent are the golden standard for decreasing the mortality and morbidity. Diabetes mellitus has been found to be an important factor to increase mortality rates of patients with Fournier's gangrene.

  16. Acute recurrent pancreatitis: Etiopathogenesis, diagnosis and treatment

    Science.gov (United States)

    Testoni, Pier Alberto

    2014-01-01

    Acute recurrent pancreatitis (ARP) refers to a clinical entity characterized by episodes of acute pancreatitis which occurs on more than one occasion. Recurrence of pancreatitis generally occurs in a setting of normal morpho-functional gland, however, an established chronic disease may be found either on the occasion of the first episode of pancreatitis or during the follow-up. The aetiology of ARP can be identified in the majority of patients. Most common causes include common bile duct stones or sludge and bile crystals; sphincter of oddi dysfunction; anatomical ductal variants interfering with pancreatic juice outflow; obstruction of the main pancreatic duct or pancreatico-biliary junction; genetic mutations; alcohol consumption. However, despite diagnostic technologies, the aetiology of ARP still remains unknown in up to 30% of cases: in these cases the term “idiopathic” is used. Because occult bile stone disease and sphincter of oddi dysfunction account for the majority of cases, cholecystectomy, and eventually the endoscopic biliary and/or pancreatic sphincterotomy are curative in most of cases. Endoscopic biliary sphincterotomy appeared to be a curative procedure per se in about 80% of patients. Ursodeoxycholic acid oral treatment alone has also been reported effective for treatment of biliary sludge. In uncertain cases toxin botulin injection may help in identifying some sphincter of oddi dysfunction, but this treatment is not widely used. In the last twenty years, pancreatic endotherapy has been proven effective in cases of recurrent pancreatitis depending on pancreatic ductal obstruction, independently from the cause of obstruction, and has been widely used instead of more aggressive approaches.

    Full Text Available Opioid intoxications and overdose are associated with high rates of morbidity and mortality. Opioid overdose may occur in the setting of intravenous or intranasal heroin use, illicit use of diverted opioid medications, intentional or accidental misuse of prescription pain medications, or iatrogenic overdose. In this review, we focused on the epidemiology of illict opioid use in the United States and on the mechanism of action of opioid drugs. We also described the signs and symptoms, and diagnoses of intoxication and overdose. Lastly, we updated the reader about the most recent recommendations for treatment and prevention of opioid intoxications and overdose.

    This paper focuses on "cheating" in modern day athletics from youth through professional sports. We briefly summarize a history of cheating in the sports world. We examine the current role cheating plays in sports as well as its causes including, psychodynamic issues, the development of personality disorders and how personality traits become pathological resulting in deception, dishonesty, and underhandedness. We describe management and treatment including psychotherapeutic intervention as well as medication. Finally we discuss a systems approach involving outreach to coaches, families, and related sports organizations (like FIFA, WADA, etc) or the professional leagues which have institutional control and partial influence on the athlete.

    Hemoglobinopathies are among the most common inherited diseases around the world. They have become much more common recently in northern and central Europe, including Germany, due to immigration. Selective review of the literature with consideration of national guidelines. The hemoglobinopathies encompass all genetic diseases of hemoglobin. They fall into two main groups: thalassemia syndromes and structural hemoglobin variants (abnormal hemoglobins). α- and β-thalassemia are the main types of thalassemia; the main structural hemoglobin variants are HbS, HbE and HbC. There are many subtypes and combined types in each group. The highly variable clinical manifestations of the hemoglobinopathies range from mild hypochromic anemia to moderate hematological disease to severe, lifelong, transfusion-dependent anemia with multiorgan involvement. Stem-cell transplantation is the preferred treatment for the severe forms of thalassemia. Supportive, rather than curative, treatment consists of periodic blood transfusions for life, combined with iron chelation. Drugs to treat the symptoms of sickle-cell disease include analgesics, antibiotics, ACE inhibitors and hydroxyurea. Blood transfusions should be given only when strictly indicated. More than 90% of patients currently survive into adulthood. Optimally treated patients have a projected life span of 50 to 60 years. Hemoglobinopathies are a public health issue in today's multiethnic German population. Adequate care of the affected patients requires a wide variety of diagnostic and therapeutic measures.

    Rosenberg, Ari; Agulnik, Mark

    2018-03-15

    Epithelioid hemangioendothelioma (EHE) is an extremely rare sarcoma, as such it can pose a clinical dilemma based solely on its rarity. Also, the spectrum of disease varies greatly between an indolent disease and aggressive disease with widespread metastases. In our clinical practice, the primary focus has been to get a handle on the aggressive nature of the disease, which will then dictate how urgently one needs to treat the patient. Pathological review with immunohistochemistry and molecular characterization is paramount. Our treatment strategy is watch-and-wait versus active therapy on clinical trial or based on results of prior clinical trials. There is evidence to support the use of chemotherapeutics and targeted therapies specifically focusing on anti-angiogenesis. The current landscape of oncology with the emergence and excitement of immunotherapy could also translate in a role for immunotherapy in this disease. While rare, there is certainly no reason that research and trials for patients with EHE should not remain on utmost importance for those of us who specialize in the treatment of sarcomas.

    2010-03-01

    Pyogenic osteomyelitis is still frequently seen in the developing world and the treatment of chronic osteomyelitis presents a considerable challenge despite advances in microbiological techniques, antibiotics and surgical techniques. Acute haematogenous osteomyelitis is commoner in children. In the pre-antibiotic era, mortality rate was high and progression to chronic osteomyelitis was common. A near similar scenario still exists in many developing countries due to the combination of inappropriate and/or inadequate antibiotic therapy, delayed presentation and unorthodox interventions by traditional healers. Chronic osteomyelitis may result from poorly treated or untreated acute osteomyelitis, open fractures, surgery for an array of orthopaedic conditions and from contiguous spread from infected soft tissue as may occur in diabetic foot infections. A large array of treatment techniques hinged on sequestrectomy/ debridement, management of dead space, improvement of oxygenation and perfusion to ischaemic tissue exist. Despite these, total eradication of disease is difficult. This article summarizes the pathology and methods of management available for pyogenic osteomyelitis. In its acute and chronic forms, the disease is likely to remain prevalent in the developing world until issues of ignorance, poverty and prompt access to appropriate and efficacious medical care are addressed.

    We introduce an example of a rigorous, quantitative method for quality improvement in lung cancer care-delivery. Computer process modeling methods are introduced for lung cancer diagnosis, staging and treatment selection process. Two types of process modeling techniques, discrete event simulation (DES) and analytical models, are briefly reviewed. Recent developments in DES are outlined and the necessary data and procedures to develop a DES model for lung cancer diagnosis, leading up to surgical treatment process are summarized. The analytical models include both Markov chain model and closed formulas. The Markov chain models with its application in healthcare are introduced and the approach to derive a lung cancer diagnosis process model is presented. Similarly, the procedure to derive closed formulas evaluating the diagnosis process performance is outlined. Finally, the pros and cons of these methods are discussed.

  3. Obesity: Pathophysiology and Intervention

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available Obesity presents a major health hazard of the 21st century. It promotes co-morbid diseases such as heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Excessive energy intake, physical inactivity, and genetic susceptibility are main causal factors for obesity, while gene mutations, endocrine disorders, medication, or psychiatric illnesses may be underlying causes in some cases. The development and maintenance of obesity may involve central pathophysiological mechanisms such as impaired brain circuit regulation and neuroendocrine hormone dysfunction. Dieting and physical exercise offer the mainstays of obesity treatment, and anti-obesity drugs may be taken in conjunction to reduce appetite or fat absorption. Bariatric surgeries may be performed in overtly obese patients to lessen stomach volume and nutrient absorption, and induce faster satiety. This review provides a summary of literature on the pathophysiological studies of obesity and discusses relevant therapeutic strategies for managing obesity.

    Full Text Available Intussusception is the most common form of acquired gastrointestinal obstruction in children. The aim is to study the features of clinical course and treatment strategy for intussusception in children and to analyze limitations of diagnostic, clinical and special research methods. Materials and methods of the study. The analysis of treatment outcomes has been carried out in 272 children in pediatric surgery clinic from 2004 to 2015. We have developed the objective criteria for evaluation of intussusception stages that correlate with the degree of endotoxemia, changes in respiratory function and circulation, the disorders of gut motility, as well as ultrasound of the abdominal organs. Results and discussion. Patients with intussusception stage I (233 children had no signs of endotoxemia or they were non-significant. In 10 children we performed surgery, in 4 cases — laporoscopically. Of the 32 patients with stage II, in 8 cases the intussusception was straightened conservatively on the first try. We don’t make a second attempt in children with intussusception stage II. Surgical straightening was perfomed in 24 patients. Intussusception stage III in children (7 patients had signs of third degree endotoxemia. All patients of the third stage of intussusception underwent median laparotomy. In 5 cases we have detected intussusceptum necrosis, and these children were made bowel resection followed by the imposition of final ileostomy and intubation of the small intestine. In the rest (2 of patients, we managed to straighten the intussusceptum, and the gut was recognized as vital. Imposing primary anastomosis after the bowel resection in peritonitis we consider unacceptable. Conclusions. 1. Comprehensive survey of children using laboratory and instrumental methods became the basis for the allocation of 3 stages of intussusception, which correlated with the degree of endotoxemia and impaired bowel functions: stage I — compensated; stage II

    2016-04-01

    Castleman's disease is not just a single disease but rather an uncommon, heterogeneous group of nonclonal lymphoproliferative disorders, which have a broad spectrum of clinical expression. Three histological types have been reported, along with several clinical forms according to clinical presentation, histological substrate and associated diseases. Interleukin-6, its receptor polymorphisms, the human immunodeficiency virus and the human herpes virus 8 are involved in the etiopathogenesis of Castleman's disease. The study of this disease has shed light on a syndrome whose incidence is unknown. Despite recent significant advances in our understanding of this disease and the increasing therapeutic experience with rituximab, tocilizumab and siltuximab, there are still difficult questions concerning its aetiology, prognosis and optimal treatment.

    2012-11-01

    Thyrotoxic storm is a life-threatening condition requiring emergency treatment. Neither its epidemiological data nor diagnostic criteria have been fully established. We clarified the clinical and epidemiological characteristics of thyroid storm using nationwide surveys and then formulate diagnostic criteria for thyroid storm. To perform the nationwide survey on thyroid storm, we first developed tentative diagnostic criteria for thyroid storm, mainly based upon the literature (the first edition). We analyzed the relationship of the major features of thyroid storm to mortality and to certain other features. Finally, based upon the findings of these surveys, we revised the diagnostic criteria. Thyrotoxic storm is still a life-threatening disorder with over 10% mortality in Japan.

    Baijens, Laura W J; Koetsenruijter, Krista; Pilz, Walmari

    2013-06-01

    This narrative review summarizes published studies on diagnostic examinations and therapeutic interventions for phagophobia. The electronic databases Embase, PubMed, PsycINFO(®), and The Cochrane Library were used. The literature search was limited to publications in the English, German, French, Spanish, or Dutch language. The original articles are summarized in the present narrative review. The body of literature on phagophobia and swallowing fear remains very limited; only 12 studies were found. The present narrative review discovered heterogeneity in the definitions of phagophobia or similar syndromes. A systematic review, including a qualitative analysis, was planned but not carried out as studies were not of sufficient quality to warrant doing so. All the studies had severe methodological shortcomings. In general, the conclusions could not be compared across the studies because of the different study designs, small populations, different ways of evaluating and treating phagophobia, and complex combinations of treatments. A general conclusion is provided.

    Herpes genitalis is caused by the herpes simplex virus type 1 or type 2 and can manifest as primary or recurrent infection. It is one of the most common sexually transmitted infections and due to associated physical and psychological morbidity it constitutes a considerable, often underestimated medical problem. In addition to providing the reader with basic knowledge of the pathogen and clinical presentation of herpes genitalis, this review article discusses important aspects of the laboratory diagnostics, antiviral therapy and prophylaxis. The article is aimed at all health-care workers managing patients with herpes genitalis and attempts to improve the often suboptimal counselling, targeted use of laboratory diagnostics, treatment and preventive measures provided to patients.

    International Nuclear Information System (INIS)

    1998-01-01

    This publication is directed at medical professionals who may be involved in the management of radiation injuries starting from the first few hours or days after an exposure of undefined severity (i.e. those handling the emergency situation may not know the extent and severity of the accident). Experience has shown that in addition to occupational physicians, the complete management of an emergency case involves other professionals such as haematologists, oncologists, plastic surgeons, dermatologists, vascular surgeons, psychiatrists and consultants in other medical specialities. The principal aim of this publication is to provide guidelines to enable medical professionals to carry out prompt diagnostic measures and to offer emergency treatment. This report provides information in tabulated form on clinical criteria for dose assessment. Additionally, it discusses the appropriate dose-effect relationship in cases of external radiation involving either total body or local exposures, as well as internal contamination

    2014-01-01

    Hilar cholangiocarcinoma (HC) is a rare disease with a poor prognosis which typically presents in the 6th decade of life. Of the 3,000 cases seen annually in the United States, less than one half of these tumors are resectable. A variety of risk factors have been associated with HC, most notably primary sclerosing cholangitis (PSC), biliary stone disease and parasitic liver disease. Patients typically present with abdominal pain, pruritis, weight loss, and jaundice. Computed topography (CT), magnetic resonance imaging (MRI), and ultrasound (US) are used to characterize biliary lesions. Endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC) assess local ductal extent of the tumor while allowing for therapeutic biliary drainage. MRCP has demonstrated similar efficacies to PTC and ERCP in identifying anatomic extension of tumors with less complications. Treatment consists of surgery, radiation, chemotherapy and photodynamic therapy. Biliary drainage of the future liver remnant should be performed to decrease bilirubin levels thereby facilitating future liver hypertrophy. Standard therapy consists of surgical margin-negative (R0) resection with extrahepatic bile duct resection, hepatectomy and en bloc lymphadenectomy. Local resection should not be undertaken. Lymph node invasion, tumor grade and negative margins are important prognostic indicators. In instances where curative resection is not possible, liver transplantation has demonstrated acceptable outcomes in highly selected patients. Despite the limited data, chemotherapy is indicated for patients with unresectable tumors and adequate functional status. Five-year survival after surgical resection of HC ranges from 10% to 40% however, recurrence can be as high as 50-70% even after R0 resection. Due to the complexity of this disease, a multi-disciplinary approach with multimodal treatment is recommended for this complex disease. PMID:24696835

    Accidental exposure to ionising radiation may occur during such catastrophic events as the Chernobyl accident in 1986 or for days and weeks as in Goiania in 1987 and in the military camp during the training of soldiers in Lilo/Georgia in 1997 as well as in medical institutions. The cutaneous symptoms after radiation exposure are based on a combination of inflammatory processes and alteration of cellular proliferation as a result of a specific pattern of transcriptionally activated pro-inflammatory cytokines and growth factors. They follow a time course consisting of prodromal erythema, manifestation, chronic stage, late stage and they are referred to as Cutaneous Radiation Syndrome. The time course depends on several factors such as the applied radiation dose, radiation quality, individual radiation sensitivity, the extent of contamination and absorption and volume of the skin. For diagnostics of the cutaneous radiation syndrome the following procedures are used: 7.5 MHz to 20 MHz-B-scan-sonography, thermography, capillary microscopy, profilometry, nuclear magnetic resonance imaging, bone scintigraphy and histology. Based on the results of experimental and clinical research of the last years pharmacotherapy of the cutaneous radiation syndrome includes topic or systemic application of corticosteroids, gamma-interferon, pentoxifylline and vitamin E and superoxide dismutase. The treatment depends on the stage of the cutaneous radiation syndrome. Due to the complexity of the clinical manifestations of radiation disease in most patients an interdisciplinary treatment in specialized centres is necessary. Dermatologists are asked to perform in most cases life-long therapy and follow-up of the patients. (author)

    Burning mouth syndrome (BMS) is defined as a chronic pain condition characterized by a burning sensation in the clinically healthy oral mucosa. It is difficult to diagnose BMS because there is a discrepancy between the severity, extensive objective pain felt by the patient and the absence of any clinical changes of the oral mucosa. This review presents some aspects of BMS, including its clinical diagnosis, classification, differential diagnosis, general treatment, evolution and prognosis.

    The diagnosis of infective endocarditis is often delayed in clinical practice. Timely diagnosis and rapid antibiotic treatment is important. Higher age of patients, new risk factors, and increasing use of intravascular prosthetic materials resulted in changes in microbial spectrum. Nowadays, nonspecific symptoms, critically ill patients, and immunocompromised patients require a high level of diagnostic expertise.The new guidelines from the European Society of Cardiology provide various diagnostic algorithms and recommendations for antibiotic treatment. The new guidelines also recommend the formation of an endocarditis team with various medical disciplines, including a cardiac surgeon, to improve treatment because in half of all endocarditis patients, antibiotic therapy alone does not result in successful management of the infection. If complications occur, early surgical treatment should be performed.In this overview, diagnostic strategies and therapeutic approaches for the treatment of infectious endocarditis according to the current guidelines and aspects of surgical treatment are provided.

  14. Dysthymia and Apathy: Diagnosis and Treatment

    Ishizaki, Junko; Mimura, Masaru

    2011-01-01

    Dysthymia is a depressive mood disorder characterized by chronic and persistent but mild depression. It is often difficult to be distinguished from major depression, specifically in its partially remitted state because “loss of interest” or “apathy” tends to prevail both in dysthymia, and remitted depression. Apathy may also occur in various psychiatric and neurological disorders, including schizophrenia, stroke, Parkinson's disease, progressive supranuclear palsy, Huntington's disease, and dementias such as Alzheimer's disease, vascular dementia, and frontotemporal dementia. It is symptomatologically important that apathy is related to, but different from, major depression from the viewpoint of its causes and treatment. Antidepressants, especially noradrenergic agents, are useful for depression-related apathy. However, selective serotonin reuptake inhibitors (SSRIs) may be less effective for apathy in depressed elderly patients and have even been reported to worsen apathy. Dopaminergic agonists seem to be effective for apathy. Acetylcholine esterase inhibitors, methylphenidate, atypical antipsychotics, nicergoline, and cilostazol are another choice. Medication choice should be determined according to the background and underlying etiology of the targeting disease. PMID:21747995

    2014-08-01

    Narcolepsy in children is a serious disorder marked by a chronic course and lifelong handicap in school performance and choice of employment, by free time activity limitation, and by behavior and personality changes, all of which constitute a major influence on the quality of life. Increased daytime sleepiness may be the only sign at the disease onset, with attacks of sleep becoming longer and lasting up to hours. Also present may be confusional arousals with features of sleep drunkenness. Paradoxically, preschool and young children may show inattentiveness, emotional lability, and hyperactive behavior. Cataplexy may develop after onset of sleepiness and affect mainly muscles of the face. Hypnagogic hallucinations and sleep paralysis are seldom present. Multiple Sleep Latency Test criteria are not available for children younger than 6 years. The haplotype (HLA-DQB1:0602) can be associated with the disorder; however, the best predictor of narcolepsy-cataplexy is hypocretin deficiency. The treatment generally used in adults is regarded as off-label in childhood, which is why the management of pediatric narcolepsy is difficult.

    Neuroblastoma is a lethal and not uncommon tumor in childhood. Early detection and display of the spread of the tumor is highly desirable for proper treatment. Nine children suspected of having neuroblastomas were examined by I-131 metaiodobenzylguanidine (I-131 MIBG) imaging. In two recent studies I-123 metaiodobenzylguanidine (I-123 MIBG) was used. A primary adrenal neuroblastoma was correctly identified in three cases. In two patients additional tumor sites were found. In one patient, who was in complete remission, no pathologic accumulation of I-131 MIBG was found. I-131 MIBG images were also normal in four patients with other types of neoplastic diseases. A boy with multiple metastases was treated with 100 mCi of I-131 MIBG. He developed transient gastrointestinal illness and there was no regression of the tumor deposits. In one girl with a large adrenal neuroblastoma high uptake of I-131 MIBG was observed. She received two therapy doses of I-131 MIBG (35 mCi and 75 mCi) with curative intention giving a total absorbed dose in the tumor of approximately 76 Gy. In spite of high retention of radioactivity in the tumor, regression did not occur, but her general condition was improved. In the present study, images of superior quality were obtained with I-123 MIBG imaging. It is concluded that imaging using I-131 MIBG or I-123 MIBG should be used in both the initial evaluation and the follow-up of children with neuroblastoma

    2012-10-01

    This review focuses on the recent developments in the epidemiology, burden of disease, diagnostic tests, and treatment of fascioliasis. Recent epidemiologic data suggest that either the endemic areas are expanding or disease is being recognized in areas where it was not previously observed. In addition, recent data highlight the effects of fascioliasis on childhood anemia and nutrition. Diagnosis remains problematic, but newer diagnostic tests including antibody, antigen, and DNA detection tests may facilitate earlier diagnosis. Recent studies suggest that point-of-care testing may soon be possible. Treatment with triclabendazole is effective, but resistance is emerging in livestock and may pose a threat for patients. Fascioliasis continues to emerge as an important neglected disease, with new studies highlighting the under-recognized burden of disease. Further studies are needed on burden of disease, improved diagnosis, and alternative to triclabendazole treatment.

    Prior to the development of type 2 diabetes, glucose levels increase into the prediabetic states of isolated impaired fasting glycaemia (i-IFG), isolated impaired glucose tolerance (i-IGT), or combined IFG/IGT. A better understanding of the aetiology and pathophysiology of the prediabetic states...... might give a basis for the development of individualised prevention and treatment strategies for type 2 diabetes. Several studies have examined mechanisms and potential aetiological factors leading to the development of the different prediabetic states. The pathophysiology of i-IFG seems to include...... the following key defects: reduced hepatic insulin sensitivity, stationary beta cell dysfunction and/or chronic low beta cell mass, altered glucagon-like peptide-1 secretion and inappropriately elevated glucagon secretion. Conversely, the prediabetic state i-IGT is characterised by reduced peripheral insulin...

    2016-11-01

    Full Text Available As the leading cause of morbidity and cancer related-death worldwide, lung cancer has a serious threat to human health. Exosomes are nanoscale lipid membrane vesicles derived from multivesicles, which containing active biomolecules including proteins, lipids, nucleic acids and etc. Exosomes play important roles in lung cancer initiation and progression by promoting the formation of tumor microenvironment, enhancing tumor invasive and metastasis capability, leading to immunosuppression and resistance to chemoradiotherapy, and also have the application value in early diagnosis and treatment. This review summarizes the research progress of exosomes in tumor initiation and progression, and its roles in diagnosis and treatment of lung cancer.

    Full Text Available Night terrors and sleepwalking are arousal disorders that occur during the first third of night. Combined existence of sleep disorders are rare phenomenon and found to be associated with behavioural and emotional problems. It becomes difficult to diagnose among sleep disorders and epilepsy is an important differential diagnosis. Management with combined approach of pharmacotherapy and psychological counselling is safe and effective. Here, we present a case of night terrors and sleepwalking to highlight the importance of diagnosis and treatment in this condition. To conclude, all medical professionals need to be aware of different parasomnias and its treatment options.

  3. Diagnosis and management of neuropathic pain: a balanced approach to treatment.

    2003-12-01

    To provide nurse practitioners with a conceptual framework from which to diagnose and manage chronic neuropathic pain, specifically postherpetic neuralgia (PHN). A current review of the available treatment options for the management of neuropathic pain and PHN is provided. A comprehensive literature review was conducted. Clinical articles, meta-analyses, and reviews were selected for their relevance to the diagnosis and management of chronic neuropathic pain and PHN. Managing patients with chronic neuropathic pain is a common clinical challenge due to variability in individual symptoms, mechanisms, and treatment responses. In patients with PHN, a balanced treatment approach focusing on efficacy, safety, and tolerability is recommended. With appropriate treatment, most patients are able to achieve clinically significant relief from neuropathic pain. Diagnosis and management of neuropathic pain syndromes is challenging. Because of the complexity of chronic pain, successful long-term treatment can be especially difficult (Nicholson, 2003b). While most acute pain is nociceptive (i.e., a response to noxious stimuli), chronic pain can be nociceptive, neuropathic, or of mixed origin. PHN is a chronic pain syndrome that can last for years, causing physical and social disability and psychological distress (Kanazi, 2000). Despite major recent advances in the treatment of PHN, many patients remain refractory to current therapy (Dworkin, 2003). For practicing clinicians, including nurse practitioners, viewing pain as a disease rather than a symptom is the first step towards its successful management. Understanding the pathophysiology of chronic pain and emerging treatment paradigms for the management of neuropathic pain and PHN is critical to optimal care.

    This study reports a case of parasitism by the giant kidney worm, Dioctophyma renale, diagnosed in the right kidney of a domestic dog. An adult female German Shepherd was attended with clinical history of prostration and hyporexia. The hemogram showed changes compatible with an inflammatory process, for that reason, an abdominal ultrasound was requested. Ultrasound image suggested the presence of D. renale in the right kidney. The diagnosis was confirmed after urinalysis due to the presence of dioctophymas ova in the urinary sediment. Surgical treatment was made and the animal had an excellent recovery after the nephrectomy was performed. Generally, in almost all cases, parasitism by D. renale in domestic dogs is a necropsy finding, nevertheless imaging techniques as sonography and laboratorial exams as urinalysis have been proven to be important tools to achieve diagnosis. The purpose of this study is to report a case of parasitism by D. renale where diagnosis and treatment were made in time to allow the patient's recovery.

    For the treatment of primary dysmenorrhea, professor ZHAO Jiping focuses on meridian diagnosis and inspection, and uses pressing methods to locate the response points along the meridian, including acupoints and aishi points. During the stage of attack, it is essential to press along the spleen meridian, mainly Sanyinjiao (SP 6), Diji (SP 8) and Yinlingquan (SP 9); during the stage of remission, it is essential to press along the bladder meridian and stomach meridian, mainly Ganshu (BL 18), Pishu (BL 20), Weishu (BL 21), Shenshu (BL 23) and Zusanli (ST 36). The differences between deficiency syndrome and excess syndrome lead to the different feelings of doctors and patients. Combined with the results of meridian diagnosis and inspection, the aim of treatment can be achieved by different acupuncture methods. Professor ZHAO pays attention to the treatment of accompanied symptoms and timing of treatment, since the relief of accompanied syndromes and selection of timing are keys to relieving patient's pain.

    Dual-diagnosis mentally ill patients, i.e. those characterized with substance abuse problems combined with mental health problems, are a challenge both for systems treating substance abusers and for mental health services. These patients are not easily integrated in either of these healthcare systems and/or are treated only for one aspect of their problem by each of these systems. For such patients it is necessary to create a separate treatment model, combining care of the problem of substance abuse and attention to the patient's mental pathology, according to his individual personality traits. For purposes of this programme a treatment setting operating on the model of a therapeutic community is proposed. This setting will open an affiliated treatment programme for dual-diagnosed patients in a separate treatment programme that is not part of the therapeutic community but will be affiliated with it and will accept dual-diagnosis patients.

    Molar-Incisor Hypomineralisation (MIH) is a congenital disease which increases in prevalence. It affects permanent first molars and, often to a lesser degree, permanent incisors with variable severity. The aetiology is unknown, but different hypotheses have been advanced. Differential diagnosis is mandatory not to confound MIH with other diseases. Treatment consists in a minimally invasive approach by reinforcing and protecting the existing dental structure. In more severe cases, restorative treatment may be indicated.

    Multiple sclerosis is a major demyelinating disease of the central nervous system. It has a significant economic and social impact. Its etiology is unclear, although there are several hypotheses, such as infections or genetics. In its pathophysiology, it seems that immune activation attacks the myelin sheath, causing a progressive and irreversible axonal degeneration. The disease produces a variety of symptoms, and diagnosis requires fulfilling a number of criteria and the exclusion of other possible causes. The role of neuroimaging is very important, especially Magnetic Resonance Imaging. Despite the availability of disease-modifying drugs, none of them are able to halt its progress, and the most useful drugs are those designed to alleviate the symptoms of outbreaks. Overall, multiple sclerosis requires a significant effort in research to clarify not only why and how it occurs, as well as the development of new measures to improve quality of life of affected patients.

    Acute appendicitis (AA) is among the most common cause of acute abdominal pain. Diagnosis of AA is challenging; a variable combination of clinical signs and symptoms has been used together with laboratory findings in several scoring systems proposed for suggesting the probability of AA and the possible subsequent management pathway. The role of imaging in the diagnosis of AA is still debated, with variable use of US, CT and MRI in different settings worldwide. Up to date, comprehensive clinical guidelines for diagnosis and management of AA have never been issued. In July 2015, during the 3rd World Congress of the WSES, held in Jerusalem (Israel), a panel of experts including an Organizational Committee and Scientific Committee and Scientific Secretariat, participated to a Consensus Conference where eight panelists presented a number of statements developed for each of the eight main questions about diagnosis and management of AA. The statements were then voted, eventually modified and finally approved by the participants to The Consensus Conference and lately by the board of co-authors. The current paper is reporting the definitive Guidelines Statements on each of the following topics: 1) Diagnostic efficiency of clinical scoring systems, 2) Role of Imaging, 3) Non-operative treatment for uncomplicated appendicitis, 4) Timing of appendectomy and in-hospital delay, 5) Surgical treatment 6) Scoring systems for intra-operative grading of appendicitis and their clinical usefulness 7) Non-surgical treatment for complicated appendicitis: abscess or phlegmon 8) Pre-operative and post-operative antibiotics.

    2014-09-01

    Full Text Available Narcolepsy is a lifelong sleep disorder characterized by excessive daytime sleepiness, cataplexy, hypnagogic hallucination, and sleep paralysis. The exact cause remains unknown, but there is significant evidence that hypocretin deficiency plays an integral role. There have been advances in the understanding of the pathogenesis of narcolepsy. It has a negative effect on the quality of life and can restrict the patients from certain careers and activities. Diagnosis relies on patient history and objective data gathered from polysomnography and multiple sleep latency testing. Treatment focuses on symptom relief through medication, education, and behavioral modification. Both classic pharmacological treatments as well as newer options have significant problems, especially because of side effects and abuse potential. Some novel modalities are being examined to expand options for treatment. In this review, the pathophysiological, clinical, and pharmacotherapeutic aspects of narcolepsy are discussed.

    Full Text Available Benign paroxysmal positional vertigo is the cause of peripheral vertigo, which only takes seconds posed by certain head and body position and led to severe attacks of vertigo. Therefore, it is a disturbance that causes a continuous fear of fall and anxiety in some patients. Although benign paroxysmal positional vertigo is the most common cause of peripheral vertigo, it may cause unnecessary tests, treatment costs and the loss of labor due to the result of the delay in the diagnosis and treatment stages. Diagnosis and treatment of this disease is easy. High success rates can be achieved with appropriate repositioning maneuvers after taking a detailed medical history and accurate assessment of accompanying nystagmus. The aim of this paper was to review the updated information about benign paroxysmal positional vertigo. [Archives Medical Review Journal 2015; 24(4.000: 555-564

    Described is the importance of exact diagnosis by complaint, physical and imaging findings, and of effective conservative or open surgical treatment in cervico-omo-branchialgia (COB). COB derives from diseases at cervical vertebra, thoracic outlet, upper limb and others. Imaging in the diagnosis involves the flat plate roentgenography, and MRI for lesions in the cervical vertebra, disk, vertebral canal, spinal cord, nerve root tube and muscle to evaluate hernia, tumor, infection, fracture, pressures of nerve root and spinal cord. CT is excellent for bony lesions of the cervical vertebra and ligament. Treatment with nerve block is done usually under X-ray fluoroscopy. Conservative treatment is usual and evaluation is important in its process not to miss the surgical timing. (R.T.)

To assess the new therapies for treatment of rheumatoid arthritis, the more uses models are: that of the arthritis induced by adjuvant drugs in rats and the arthritis induced by collagen in rats and mice. Other new models show limited data. Effectiveness of several compounds reveals that its therapeutic effect is more predictive of the clinical effect in the human being when models of arthritis due to adjuvant drugs and collagen than data from an only one model.

    Elite athletes have a high prevalence of asthma and exercise-induced bronchoconstriction. Although respiratory symptoms can be suggestive of asthma, the diagnosis of asthma in elite athletes cannot be based solely on the presence or absence of symptoms; diagnosis should be based on objective...... measurements, such as the eucapnic voluntary hyperpnea test or exercise test. When considering that not all respiratory symptoms are due to asthma, other diagnoses should be considered. Certain regulations apply to elite athletes who require asthma medication for asthma. Knowledge of these regulations...... is essential when treating elite athletes. This article is aimed at physicians who diagnose and treat athletes with respiratory symptoms. It focuses on the pathogenesis of asthma and exercise-induced bronchoconstriction in elite athletes and how the diagnosis can be made. Furthermore, treatment of elite...

    Dystonias represent a heterogeneous group of movement disorders responsible for sustained muscle contraction, abnormal postures, and muscle twists. It can affect focal or segmental body parts or be generalized. Primary dystonia is the most common form of dystonia but it can also be secondary to metabolic or structural dysfunction, the consequence of a drug's side-effect or of genetic origin. The pathophysiology is still not elucidated. Based on lesion studies, dystonia has been regarded as a pure motor dysfunction of the basal ganglia loop. However, basal ganglia lesions do not consistently produce dystonia and lesions outside basal ganglia can lead to dystonia; mild sensory abnormalities have been reported in the dystonic limb and imaging studies have shown involvement of multiple other brain regions including the cerebellum and the cerebral motor, premotor and sensorimotor cortices. Transcranial magnetic stimulation (TMS) is a non-invasive technique of brain stimulation with a magnetic field applied over the cortex allowing investigation of cortical excitability. Hyperexcitability of contralateral motor cortex has been suggested to be the trigger of focal dystonia. High or low frequency repetitive TMS (rTMS) can induce excitatory or inhibitory lasting effects beyond the time of stimulation and protocols have been developed having either a positive or a negative effect on cortical excitability and associated with prevention of cell death, γ-aminobutyric acid (GABA) interneurons mediated inhibition and brain-derived neurotrophic factor modulation. rTMS studies as a therapeutic strategy of dystonia have been conducted to modulate the cerebral areas involved in the disease. Especially, when applied on the contralateral (pre)-motor cortex or supplementary motor area of brains of small cohorts of dystonic patients, rTMS has shown a beneficial transient clinical effect in association with restrained motor cortex excitability. TMS is currently a valuable tool to improve

    2016-05-01

    Hyponatraemia is the most common electrolyte imbalance in neurosurgical patients. Acute hyponatraemia is particularly common in neurosurgical patients after any type of brain insult, including brain tumours and their treatment, pituitary surgery, subarachnoid haemorrhage or traumatic brain injury. Acute hyponatraemia is an emergency condition, as it leads to cerebral oedema due to passive osmotic movement of water from the hypotonic plasma to the relatively hypertonic brain which ultimately is the cause of the symptoms associated with hyponatraemia. These include decreased level of consciousness, seizures, non-cardiogenic pulmonary oedema or transtentorial brain herniation. Prompt treatment is mandatory to prevent such complications, minimize permanent brain damage and therefore permit rapid recovery after brain insult. The infusion of 3% hypertonic saline is the treatment of choice with different rates of administration based on the severity of symptoms and the rate of drop in plasma sodium concentration. The pathophysiology of hyponatraemia in neurotrauma is multifactorial; although the syndrome of inappropriate antidiuresis (SIADH) and central adrenal insufficiency are the commonest causes encountered. Fluid restriction has historically been the classical treatment for SIADH, although it is relatively contraindicated in some neurosurgical patients such as those with subarachnoid haemorrhage. Furthermore, many cases admitted have acute onset hyponatraemia, who require hypertonic saline infusion. The recently developed vasopressin receptor 2 antagonist class of drug is a promising and effective tool but more evidence is needed in neurosurgical patients. Central adrenal insufficiency may also cause acute hyponatraemia in neurosurgical patients; this responds clinically and biochemically to hydrocortisone. The rare cerebral salt wasting syndrome is treated with large volume normal saline infusion. In this review, we summarize the current evidence based on the

    2017-03-01

    Fibrinolysis activation occurs almost universally after severe trauma. Systemic hyperfibrinolysis is a key component of acute traumatic coagulopathy and associated with poor clinical outcomes, although controversy exists over optimal treatment strategies. The mechanistic drivers and dynamics of fibrinolytic activation in response to injury and trauma resuscitation are currently unclear. Furthermore, therapeutic triggers are compounded by the lack of a sensitive and rapid diagnostic tool, with discrepancy between hyperfibrinolysis diagnosed by viscoelastic hemostatic assays versus biomarkers for fibrinolysis. Rotational thromboelastometry and thromboelastography appear capable of detecting the severest forms of hyperfibrinolysis but are relatively insensitive to moderate, yet clinically significant fibrinolytic activation. Rapid evaluation of the current status of the fibrinolytic system remains a challenge and therefore the decision whether to administer an antifibrinolytic agent should be based on available evidence from clinical trials. In line with current European guidelines, we recommend that all bleeding trauma patients, and in particular, severely injured patients with evidence of hemorrhagic shock, should receive early empiric tranexamic acid. This review explains our current knowledge of the pathophysiological pathways which induce hyperfibrinolysis in trauma hemorrhage, evaluates the available diagnostic modalities, and describes current treatment strategies.

    2015-01-01

    Summary Among the common complication of cirrhosis portal hypertension witnessed a major improvement of prognosis during the past decades. Principally due to the introduction of rational treatments based on new pathophysiological paradigms (concepts of thought) developed in the 1980s. The best example being the use of non-selective beta-blockers and of vasopressin analogs, somatostatin, and its analogs. Further refinement in the knowledge of the molecular mechanisms involved in the regulation of both the splanchnic and hepatic circulation has led to the emergence of new treatments, which are based on evidence that show not only structural but also vasoactive components increase the hepatic vascular resistance, as well as of angiogenesis. This knowledge and future improvements will most likely result in more effective treatment of portal hypertension and effective prevention of its complications in early stages. PMID:25920081

    Vega, Jennifer N.; Newhouse, Paul A.

    2014-01-01

    Mild cognitive impairment (MCI) is widely regarded as the intermediate stage of cognitive impairment between the changes seen in normal cognitive aging and those associated with dementia. Elderly patients with MCI constitute a high-risk population for developing dementia, in particular Alzheimer’s disease (AD). Although the core clinical criteria for MCI have remained largely unchanged, the operational definition of MCI has undergone several revisions over the course of the last decade and remains an evolving diagnosis. Prognostic implications of this diagnosis are becoming clearer with regard to the risk of progressive cognitive deterioration. Although patients with MCI may represent an optimal target population for pharmacological and non-pharmacological interventions, results from clinical trials have been mixed and a definitive effective treatment remains elusive. This article provides a brief overview of the evolution of the concept of MCI and reviews current diagnostic criteria, the longitudinal course of the disorder, and current and emerging treatments for MCI.

    Full Text Available Status Epilepticus (SE is a medical emergency that causes significant morbidity and mortality and requires prompt diagnosis and treatment. Although SE can be divided into two subgroups as convulsive and nonconvulsive, treatment principles are generally similar. Treatment should be prompt and underlying cause should be corrected. Although intravenous lorazepam is the first-line treatment due to a lower risk of relapse, diazepam becomes the first choice since loeazepan is not available in our country. Even though intravenous benzodiazepine stops seizures, intravenous antiepileptic drug (phenytoin, etc. should be administered at a loading dose. Patients with refractory status epilepticus should be supported with respect to vital, respiratory, metabolic and hemodynamic aspects and followed up in an intensive care unit to monitor cerebral electrical activity. The most common cause in the etiology is the cessation of antiepileptic drugs. The aim of SE treatment is to stop seizures and prevent complications and recurrence. In this paper, current diagnosis, treatment and etiology of SE are reviewed.

    Colorectal cancer is one of the most common malignant tumors in China. In 2012 one million thirty six thousand cases of colorectal cancer were diagnosed all over the world, two hundred fifty three thousand cases were diagnosed in China (accounted for 18.6%). China has the largest number of new cases of colorectal cancer in the world. Colorectal cancer has becoming a serious threat of Chinese residents' health. In 2010, the National Ministry of Health organized colorectal cancer expertise of the Chinese Medical Association to write the "Chinese Protocol of Diagnosis and Treatment of Colorectal Cancer" (2010edition), and publish it publicly. In recent years, the National Health and Family Planning Commission has organized experts to revised the protocol 2 times: the first time in 2015, the second time in 2017. The revised part of "Chinese Protocol of Diagnosis and Treatment of Colorectal Cancer" (2017 edition) involves new progress in the field of imaging examination, pathological evaluation, surgery, chemotherpy and radiotherapy. The 2017 edition of the protocol not only referred to the contents of the international guidelines, but also combined with the specific national conditions and clinical practice in China, and also included many evidence-based clinical data in China recently. The 2017 edition of the protocol would further promote the standardization of diagnosis and treatment of colorectal cancer in China, improve the survival and prognosis of patients, and benefit millions of patients with colorectal cancer and their families.

    Full Text Available The results of the pilot study of combined treatment for non-resectable cholangiocarcinoma complicated with obstructive jaundice are represented this paper. Method included percutaneous transhepatic biliary drainage, endoscopic fluorescence diagnosis, photodynamic therapy of tumor stricture, and stenting of bile ducts. Fourteen patients who underwent the treatment in the surgery department clinic of I.M. Sechenov First Moscow State Medical University were enrolled in the study. Fluorescence diagnosis and photodynamic therapy were carried out using photosensitizers photosens (0.5 mg/kg, fotolon (1 mg/kg, and radachlorin (1 mg/kg. The average light dose for one session was 115±5 J/cm2. Fluorescence diagnosis using endoscopic video-fluorescence system for endoscopy and minimally invasive surgery allowed to obtain videoassisted fluorescence image of the tumor and to measure level of photosensitizer fluorescence in tumor in all patients. Malignant tumor was confirmed by morphological study in 12 patients, biopsy of material for morphological study failed in 2 patients with Klatskin tumor. The preliminary results of combined minimally invasive treatment were assessed as promising. The survival time in 4 patients after treatment accounted for 21, 17, 13 and 11 months, respectively. For now 5 patients are under follow-up. Follow-up periods are 13 and 19 months in 2 of them and from 4 to 6 months in 3 of them. Five patients with multiple distant metastases before the treatment died in 3±1 months after therapy. The average lifetime in the treatment group is 9.5 months up to date, however the duration is expected to belonger because 5 of 14 patients are alive.

    Diagnosis of nocturnal polyuria (NP) is based on a bladder diary. Addition of a renal function profile (RFP) for analysis of concentrating and solute-conserving capacity allows differentiation of NP pathophysiology and could facilitate individualized treatment. To map circadian rhythms of water and solute diuresis by comparing participants with and without NP. This prospective observational study was carried out in Ghent University Hospital between 2011 and 2013. Participants with and without NP completed a 72-h bladder dairy. RFP, free water clearance (FWC), and creatinine, solute, sodium, and urea clearance were measured for all participants. The study participants were divided into those with (n=77) and those without (n=35) NP. The mean age was 57 yr (SD 16 yr) and 41% of the participants were female. Compared to participants without NP, the NP group exhibited a higher diuresis rate throughout the night (p=0.015); higher FWC (p=0.013) and lower osmolality (p=0.030) at the start of the night; and persistently higher sodium clearance during the night (p<0.001). The pathophysiologic mechanism of NP was identified as water diuresis alone in 22%, sodium diuresis alone in 19%, and a combination of water and sodium diuresis in 47% of the NP group. RFP measurement in first-line NP screening to discriminate between water and solute diuresis as pathophysiologic mechanisms complements the bladder diary and could facilitate optimal individualized treatment of patients with NP. We evaluated eight urine samples collected over 24h to detect the underlying problem in NP. We found that NP can be attributed to water or sodium diuresis or a combination of both. This urinalysis can be used to adapt treatment according to the underlying mechanism in patients with bothersome consequences of NP, such as nocturia and urinary incontinence.

    The incidence of radiation necrosis has increased secondary to greater use of combined modality therapy for brain tumors and stereotactic radiosurgery. Given that its characteristics on standard imaging are no different that tumor recurrence, it is difficult to diagnose without use of more sophisticated imaging and nuclear medicine scans, although the accuracy of such scans is controversial. Historically, treatment had been limited to steroids, hyperbaric oxygen, anticoagulants, and surgical resection. A recent prospective randomized study has confirmed the efficacy of bevacizumab in treating radiation necrosis. Novel therapies include using focused interstitial laser thermal therapy.

    Distant metastases occur in less than 10% of patients with differentiated thyroid carcinoma. In these patients, overall survival at 10 years is considerably reduced. Whereas cure is the initial goal of treatment, stabilisation of the disease and management of symptoms have become the primary objective in many patients with persistent radio-iodine refractory progressive disease. In the last decade, several targeted therapies have shown encouraging results in patients with advanced disease. The objective of this review is to describe the characteristics, diagnosis, overall survival, and the local and systemic available treatments for patients with distant metastases from differentiated thyroid cancer.

    2018-01-01

    Full Text Available When dactylitis is detected in a patient with psoriatic arthritis (PsA, it is necessary to use active treatment as soon as possible, since in the absence of therapy the disease progresses to joint erosion and  functional disorders. The paper considers the clinical signs and  diagnosis of PsA and notes the importance of differential diagnosis in this sign with other joint inflammatory diseases. It points to the  necessity of elaborating common approaches to an objective  assessment of the severity of dactylitis. Its immunopathogenesis and main treatment areas, including the use of biological agents (BAs,  are detailed. There are data of clinical trials that have evaluated the  efficiency of treatment for dactylitis and established that in most  cases, the use of BAs considerably reduce not only the severity of its clinical signs, but also concomitant bone marrow edema. It is noted  that the development of new pathogenetic treatments targeting a number of currently established biologically active molecules that  play an important role in the pathogenesis of dactylitis will enhance  the efficiency of treatment in patients with PsA.

    2016-11-01

    Full Text Available Disparities between African American and Caucasian men in prostate cancer (PCa diagnosis and treatment in the United States have been well established, with significant racial disparities documented at all stages of PCa management, from differences in the type of treatment offered to progression-free survival or death. These disparities appear to be complex in nature, involving biological determinants as well as socioeconomic and cultural aspects. We present a review of the literature on racial disparities in the diagnosis of PCa, treatment, survival, and genetic susceptibility. Significant differences were found among African Americans and whites in the incidence and mortality rates; namely, African Americans are diagnosed with PCa at younger ages than whites and usually with more advanced stages of the disease, and also undergo prostate-specific antigen testing less frequently. However, the determinants of the high rate of incidence and aggressiveness of PCa in African Americans remain unresolved. This pattern can be attributed to socioeconomic status, detection occurring at advanced stages of the disease, biological aggressiveness, family history, and differences in genetic susceptibility. Another risk factor for PCa is obesity. We found many discrepancies regarding treatment, including a tendency for more African American patients to be in watchful waiting than whites. Many factors are responsible for the higher incidence and mortality rates in African Americans. Better screening, improved access to health insurance and clinics, and more homogeneous forms of treatment will contribute to the reduction of disparities between African Americans and white men in PCa incidence and mortality.

    This review provides an update on the new Diagnostic and Statistical Manual (DSM) diagnosis of binge-eating disorder (BED) by presenting diagnostic criteria, associated risk factors and co-morbidities, and tools for assessment. An update on the currently available evidence-based treatments for adolescent BED is provided to help with the coordination of treatment planning for identified patients with this condition. BED is now officially included in the DSM. Research with youth has begun to show improvement from treatments such as cognitive behavioral therapy, previously shown to be useful in adults. BED is common and often begins during youth. The availability of diagnostic criteria, along with increasing knowledge about the condition and available treatments, is expected to result in improved identification and management in younger patients.

    Full Text Available Attention-deficit/hyperactivity disorder (ADHD is a prevalent neurodevelopmental disorder, often associated with other psychiatric comorbidities, functional impairments, and poor long-term outcomes. The objective of this selected review is to describe current advances and challenges in the diagnosis and treatment of ADHD. The disorder is associated with neurobiological underpinnings and is highly heterogeneous in various aspects, such as symptom profiles, cognitive impairments, and neurobiological and genetic features. The efficacy and safety of short-term pharmacological treatments across the life cycle is well studied, but further research investigating long-term treatment, impact of treatment in preschoolers, and non-pharmacological interventions is needed. Future research is also needed to better characterize the neurodevelopmental pathways of the disorder, linking clinical and neurobiological information, less investigated populations, and new interventions.

    Rare genetic diseases collectively impact a significant portion of the world's population. For many diseases there is limited information available, and clinicians can find difficulty in differentiating between clinically similar conditions. This leads to problems in genetic counseling and patient treatment. The biomedical market is affected because pharmaceutical and biotechnology industries do not see advantages in addressing rare disease treatments, or because the cost of the treatments is too high. By contrast, technological advances including DNA sequencing and analysis, together with computer-aided tools and online resources, are allowing a more thorough understanding of rare disorders. Here, we discuss how the collection of various types of information together with the use of new technologies is facilitating diagnosis and, consequently, treatment of rare diseases.

    In our country general internists are the providers of adult medical care in urban areas. In the past twenty years, with the increasing subspecialization within internal medicine and the development of advances in technology, the role of the general internist seems to be endangered. Recently much attention has been focused on this area and Divisions and Programs of General Internal Medicine have been established in most medical schools in the USA. The University of Buenos Aires instituted a Program of General Internal Medicine in its major teaching hospital in 1987. One of its purposes was to offer an educational experience to residents in the field of internal medicine primary care. This paper summarizes how this program was carried out and the subjects proposed in the area of Diagnosis and Treatment. The Program of General Internal Medicine is performed in the Outpatient Division and it is staffed by 3 faculty members and 4 fellows. Residents in Internal Medicine have a three month, full-time block rotation in the Program. A young, city dwelling, lower middle class population participates in the Program, with almost 10000 visits a year. The Program offers an experience that includes supervised patient care, an average of 100 office visits a month, and seminars and/or workshops covering topics of "Diagnosis and Treatment", "Case Presentations", "Clinical Epidemiology", "Prevention", and "Doctor-Patient Interview". In the area of Diagnosis and Treatment, the criteria used were: 1-frequency of diagnosis as determined by previous investigations, 2-relevant clinical conditions absent from the frequency list as determined by a consensus process by faculty members.(ABSTRACT TRUNCATED AT 250 WORDS)

    1963-01-01

    The increasing use of atomic energy generated by nuclear fission is necessarily accompanied by the production of large quantities of radioactive isotopes. This, together with the growing use of radioactive materials in many fields, has given added importance to practical considerations of how best to deal with accidents - should they occur - involving radioactive contamination of individuals. Such considerations require knowledge of the metabolic behaviour of various radionuclides in man and of methods of increasing their elimination from the body. Information of this type is limited, and it is therefore essential to make maximum use of those data which, are available. Analyses of earlier accidents are one important source of such data; another is experience gained from the medical administration of radioisotopes for therapeutic or diagnostic purposes. The World Health Organization and the International Atomic Energy Agency jointly sponsored a scientific meeting on the Diagnosis and Treatment of Radioactive Poisoning, in Vienna from 15 to 18 October 1962. The aim of the meeting, which followed an earlier one (The Diagnosis and Treatment of Acute Radiation Injury) sponsored by the two organizations in 1960 on another aspect of radiation protection, was to review the present state of knowledge on the diagnosis, evaluation and treatment of persons who have accidentally incorporated radioactive materials. It brought together three groups of persons: those experienced in various methods of diagnosis and treatment of patients who have been exposed (occupationally or accidentally) to radioactive material; those engaged in the clinical administration of radionuclides and the study of their behaviour in man; and those working on related problems with experimental animals. In view of the great interest of many of the topics discussed at the meeting, it was felt desirable that the information presented in the papers and brought out in the ensuing discussions should be

    Full Text Available Thalassemia (thal is an autosomal recessive, hereditary, chronic hemolytic anemia due to a partial or complete deficiency in the synthesis of α-globin chains (α-thal or β-globin chains (β-thal that compose the major adult hemoglobin (α2β2. It is caused by one or more mutations in the corresponding genes. The unpaired globin chains are unstable; they precipitate intracellularly, resulting in hemolysis, premature destruction of red blood cell [RBC] precursors in the bone marrow, and a short life-span of mature RBCs in the circulation. The state of anemia is treated by frequent RBC transfusions. This therapy results in the accumulation of iron (iron overload, a condition that is exacerbated by the breakdown products of hemoglobin (heme and iron and the increased iron uptake for the chronic accelerated, but ineffective, RBC production. Iron catalyzes the generation of reactive oxygen species, which in excess are toxic, causing damage to vital organs such as the heart and liver and the endocrine system. Herein, we review recent findings regarding the pathophysiology underlying the major symptoms of β-thal and potential therapeutic modalities for the amelioration of its complications, as well as new modalities that may provide a cure for the disease.

    Patients with Fabry disease (FD) characteristically develop peripheral neuropathy at an early age, with pain being a crucial symptom of underlying pathology. However, the diagnosis of pain is challenging due to the heterogeneous and nonspecific symptoms. Practical guidance on the diagnosis and management of pain in FD is needed. In 2014, experts met to discuss recent advances on this topic and update clinical guidance. Emerging disease-specific tools, including FabryScan, Fabry-specific Pediatric Health and Pain Questionnaire, and Würzburg Fabry Pain Questionnaire, and more general tools like the Total Symptom Score can aid diagnosis, characterization, and monitoring of pain in patients with FD. These tools can be complemented by more objective and quantifiable sensory testing. In male and female patients of any age, pain related to FD can be an early indication to start disease-specific enzyme replacement therapy before potentially irreversible organ damage to the kidneys, heart, or brain occurs. To improve treatment outcomes, pain should be diagnosed early in unrecognized or newly identified FD patients. Treatment should include: (a) enzyme replacement therapy controlling the progression of underlying pathology; (b) adjunctive, symptomatic pain management with analgesics for chronic neuropathic and acute nociceptive, and inflammatory or mixed pain; and (c) lifestyle modifications. © 2016 The Authors.

    2017-01-01

    The aim of this study was to explore the recent advances in diagnosis and treatment of gastroesophageal reflux disease (GERD). Previous studies were searched using the terms "gastroesophageal reflux disease" and "diagnosis" or "treatment" in Medline and Pubmed. Articles that were not published in the English language, manuscripts without an abstract, reviews, meta-analysis, and opinion articles were excluded from the review. After a preliminary screening, all of the articles were reviewed and synthesized to provide an overview of the contemporary approaches to GERD. GERD has a variety of symptomatic manifestations, which can be grouped into typical, atypical and extra-esophageal symptoms. Those with the highest specificity for GERD are acid regurgitation and heartburn. In the absence of other alarming symptoms, these symptoms allow one to make a presumptive diagnosis of GERD and initiate empiric therapy. GERD-associated complications include erosive esophagitis, peptic stricture, Barrett's esophagus, esophageal adenocarcinoma and pulmonary disease. Management of GERD may involve lifestyle modifications, medical and surgical therapy. Medical therapy involves acid suppression, which can be achieved with antacids, histamine-receptor antagonists or proton-pump inhibitors. Whereas most patients can be effectively managed with medical therapy, others may go on to require anti-reflux surgery after undergoing a proper pre-operative evaluation. The management of this disease requires a complex approach. Maintenance therapy of GERD after using anti-secretory drugs should be continuously monitored. © Acta Gastro-Enterologica Belgica.

  13. Challenges in the diagnosis and treatment of pulmonary arterial hypertension.

    LENUS (Irish Health Repository)

    2012-12-01

    Advances in the diagnosis and management of pulmonary arterial hypertension (PAH) have resulted in significant improvements in outcomes for patients with this devastating and progressive disease. However, because of the non-specific nature of its symptoms, and the low level of suspicion among clinicians, prompt and accurate diagnosis of PAH as a rare disease remains a challenge. This article explains some of the issues that need to be addressed when faced with a patient with suspected PAH and describes how noninvasive and invasive techniques can be used effectively to ensure an accurate diagnosis. The availability of PAH-specific therapy means that once diagnosed, patients have a much greater chance of survival than they would have had in the past. However, despite improved survival, mortality is still high and, therefore, there is still room for improvement. It is currently recommended that patients with an inadequate clinical response to treatment receive sequential combination therapy; however, supportive data are still scarce. Although there is no clear explanation, these findings may be explained by the design and end-points chosen in clinical trials, the changing population of PAH and a need to improve the management strategy in this disease. Indeed, there is a clear need for randomised controlled studies that investigate whether adopting individualised treatment strategies, including upfront combination therapy, could help to optimise long-term management of patients with PAH.

    Hepatocellular carcinoma (HCC) is one of the most common malignancies leading to high mortality rates in the general population; in cirrhotic patients, it is the primary cause of death. The diagnosis is usually delayed in spite of at-risk population screening recommendations, i.e., patients infected with hepatitis B or C virus. Hepatocarcinogenesis hinges on a great number of genetic and molecular abnormalities that lead to tumor angiogenesis and foster their dissemination potential. The diagnosis is mainly based on imaging studies such as computed tomography and magnetic resonance, in which lesions present a characteristic classical pattern of early arterial enhancement followed by contrast medium “washout” in late venous phase. On occasion, when imaging studies are not conclusive, biopsy of the lesion must be performed to establish the diagnosis. The Barcelona Clinic Liver Cancer staging method is the most frequently used worldwide and recommended by the international guidelines of HCC management. Currently available treatments include tumor resection, liver transplant, sorafenib and loco-regional therapies (alcoholization, radiofrequency ablation, chemoembolization). The prognosis of hepatocarcinoma is determined according to the lesion’s stage and in cirrhotic patients, on residual liver function. Curative treatments, such as liver transplant, are sought in patients diagnosed in early stages; patients in more advanced stages, were not greatly benefitted by chemotherapy in terms of survival until the advent of target molecules such as sorafenib.

    Full Text Available Oral lichen planus (OLP is a chronic mucocutaneous disease of unknown etiology. Its pathogenesis is multifactorial and it may affect the oral mucosa, skin and other mucous membranes. Diagnosis is based on clinic and histopathology; direct immunofluorescence techniques can also be of use. It affects about one to two percent of the population, mainly women between the fifth and sixth decades of life. In the mouth, the most affected area is the buccal mucosa, followed by the gums, tongue and/or palate. Its three most representative clinical forms are reticular, erythematous and erosive; evolution depends on the type it is. Lesion treatment is determined by the clinical form and, since no fully effective treatment has been found yet, it is directed towards controlling the disease. The treatment of choice involves topical or systemic corticosteroids, but other drugs may also be used.The aim of this paper is to gather current and relevant information about oral lichen planus: its pathogenesis, diagnosis, treatment and management.

    Full Text Available Background: Urticaria is a disease that a fth of the population shall suffer once in a lifetime. Recent clinical guidelines have proposed some fundamental changes in the diagnosis and treatment of urticaria, making the development of a national, multidisciplinary guideline, with wide acceptability among different professional groups –both specialists and primary health care workers–, necessary in Mexico. Material and method: Internationally recognized tools for guideline- development were used. An interdisciplinary group of clinical experts (some of them knowledgeable in methodology of guideline develop- ment determined the objectives and scope of the Evidence Based Clinical Practice Guideline with SCOPE. It was decided to adapt and transculturize international guidelines on the diagnosis and treatment of urticaria. With AGREE-II three high-quality guidelines (Zuberbier 2014, Sánchez-Borges 2012, Powell 2007 were selected to function as basic guidelines (BG. A set of Clinical Questions was formulated that lead to recommendations/suggestions, based on these BG, taking into account the cultural and economic background of Mexico, according to GRADE recommendation development. Results: By a formal process of discussion and voting during several working-sessions, experts and rst level healthcare physicians deter- mined the wording of the nal guideline, taking particularly care of developing a document, adjusted to the reality, values and preferences of the Mexican patients. The use of oral second generation, non-sedating antihistamines as rst line treatment is emphasized. Conclusion: This document is an Evidence Based Clinical Practice Guideline for the diagnosis and treatment of acute and chronic urticaria, based on three, high quality, international guidelines. It was developed by a multidisciplinary group. Tables and algorithms make the guideline user-friendly for both, rst line health care physicians and specialists

    2014-01-01

    Familial mediterranean fever (FMF) is the most prevalent genetically determined autoinflammatory disease. FMF significantly decreases the quality of life and limits life expectancy due to the development of amyloidosis in affected individuals. Prevalence of FMF is highest in the south-eastern Mediterraneans. In other parts of the world, its occurance is often restricted to high-risk ethnic goups. In Central Europe, experience with FMF is scarse. As for Slovakia, we have reported the first cases of FMF in ethnic Slovaks only recently. Along with their complicated fates, this has lead us to compile a comprehensive overview of the clinical picture, diagnosis and treatment of this elusive disease. Hereby we hope to be able to promote the awareness about this disease and possibly aid the diagnosis in new patients.

    2013-01-01

    Headaches affect 90% of the population sometime during their life. Most are benign and fleeting, some are serious and life-threatening, and others require ongoing medical consultation and treatment. A careful history and physical is necessary to establish a differential diagnosis and to guide the choice of testing to make an accurate diagnosis. The most common types of headaches are discussed in this review. They are divided into primary and secondary headache disorders as classified by the International Headache Society. Primary headache disorders include migraine without and with aura, cluster and tension-type headaches. Secondary headaches are those that occur as a result of some other disorder and include brain tumors, rhinosinusitis, diseases of intracranial and extracranial vasculature, and temporomandibular joint disease.

    2006-01-01

    The diagnosis, evaluation and management of antenatal hydronephrosis has undergone a two stage paradigm shift since the advent of prenatal ultrasonography in the early 1980s. Initially the identification of a large number of asymptomatic infants appeared to afford the surgeon the opportunity for preemptive intervention. However, it has now become apparent that antenatal hydronephrosis (AH) is far more difficult to interpret thanoriginally perceived. The initial enthusiasm for surgery has now been replaced by a much more conservative approach to ureteropelvic junction(UPJ) obstruction, multi-cystic dysplastic kidney(MCDK), vesicoureteral reflux and the non-refluxing megaureter. This review will highlight the postnatal evaluation of AH and include an overview of the Society for Fetal Urology grading system for hydronephrosis. The differential diagnosis and treatment options for UPJ obstruction, vesicoureteral reflux, MCDK, duplication anomalies, megaureter, and posterior urethral valves will be discussed. PMID:17619702

    2011-06-01

    Full Text Available The guidelines for the osteoporosis management were first drafted by a working group and then critically evaluated by the board of SIOMMMS. The most relevant points are: Definition: Osteoporosis is defined as a quantitative and qualitative deterioration of bone tissue leading to increased risk of fracture. Postmenopausal and senile osteoporosis are defined as primitive. Diagnosis: The cornerstone for the diagnosis of osteoporosis is the measurement of bone mineral density (BMD by DXA (dual-energy X-ray absortiometry at the femoral neck with T-score values -2.5 is usually not justified. Pharmacological intervention: The use of drugs registered for the treatment of osteoporosis are recommended when the benefits overcome the risk. This is the case only when the risk of fracture is rather high. FRAX™ is recognized as a useful tool for easily estimate the long-term fracture risk. SIOMMMS with these guidelines is committed to validate and further develop this diagnostic tool.

    Full Text Available The Gorlin-Goltz syndrome is a rare autosomal dominant hereditary condition, with complete penetrance and variable expressivity. Characterized by the appearance of multiple basaliomas, and often the development of keratocyst, it can also express itself by the presence of palmar/plantar depressions, calcification of brain sickle, and skeletal birth defects, although less frequently. This article presents two cases involving direct relatives, referred after the identification of several basaliomas and jaw cysts. After establishing the diagnosis, given the identification of three major criteria, the treatment consisted in the excision of the lesions followed, in one case, with vismodegib treatment resulting in complete remission. Gorlin-Goltz syndrome is therefore a multidisciplinary challenge, whose variable morbidity and high risk of recurrence make treatment and surveillance critical. However, new molecular targeted therapies have brought a new hope in treating these patients.

    BACKGROUND: Spinal tuberculosis is a common disease in orthopedic clinical practice; however, it is seldom reported after organ transplantation. The aim of this study was to investigate the diagnosis and treatment of spinal tuberculosis after organ transplantation. METHOD: Two cases were diagnosed as spinal tuberculosis after liver transplantation and were treated with socarboxazide, rifampicin, streptomycin and ethambutol for more than one year. RESULTS: After treatment with anti-tuberculosis drugs for several months, the symptoms of both patients clearly improved. Back pain disappeared, and erythrocyte sedimentation and body temperature returned to normal. CONCLUSIONS: We should highly suspect spinal tuberculosis if notalgia and night sweats are present after organ transplantation. Anti-tuberculosis therapy is an effective treatment for spinal tuberculosis after organ transplantation.

    2018-02-01

    Juvenile myelomonocytic leukemia (JMML) is a clonal hematopoietic disorder of infancy/early childhood, resulting from oncogenic mutations in genes involved in the Ras pathway. As JMML often exhibits an aggressive course, the timing of diagnosis and treatment is critical to outcome. Areas covered: This review summarizes current approaches to diagnosis and treatment of JMML, highlighting most recent insights into genetic and epigenetic mechanisms underlying the disease, and providing an overview of novel potential therapeutic strategies. Expert commentary: At present, allogeneic HSCT remains the only potentially effective therapy, being able to cure more than 50% of patients, relapse representing the main cause of treatment failure. Prompt HSCT is recommended for all children with NF1, somatic PTPN11 and KRAS mutations, and for most children with somatic NRAS mutations. Conversely, a 'watch and wait' strategy should be adopted in children with germline CBL mutations, specific somatic NRAS mutation, and in Noonan syndrome patients, since spontaneous resolution has been reported to occur. Novel drugs targeting relevant nodes of JMML leukemogenesis have been explored in pre-HSCT window or at relapse. The use of 5-azacytidine, a DNA-hypomethylating agent reported to induce hematologic and molecular remission in some JMML children, is currently being investigated in clinical trials.

    Candidiasis is the most common opportunistic yeast infection. Candida species and other microorganisms are involved in this complicated fungal infection, but Candida albicans continues to be the most prevalent. In the past two decades, it has been observed an abnormal overgrowth in the gastrointestinal, urinary and respiratory tracts, not only in immunocompromised patients, but also related to nosocomial infections and even in healthy individuals. There is a widely variety of causal factors that contribute to yeast infection which means that candidiasis is a good example of a multifactorial syndrome. Due to rapid increase in the incidence in these infections, this is the subject of numerous studies. Recently, the focus of attention is the treatment and, above all, the prevention of those complications. The diagnosis of candidiasis could become quite complicated. Prevention is the most effective "treatment," much more than eradication of the yeast with antifungal agents. There are several aspects to consider in the daily routine that can provide a strength protection. However, a therapeutic approach is necessary when the infection is established, and therefore, other alternatives should be explored. This review provides an overview on predisposition factors, prevention and diagnosis of candidiasis, highlighting alternative approaches for candidiasis treatment.

    Sherrill, Meredith K; Cohn, Leah A

    2015-11-01

    Cytauxzoonosis is a life-threatening hematoprotozoal disease with a rapidly progressive clinical course. Once considered a rare disease only relevant to a small geographic area, it is now recognized in more than about a third of the United States. The geographic range seems likely to increase with expansion of the range of the vector tick. Both disease diagnosis and treatment offer challenges. The acute illness is often recognized by characteristic parasitic cellular inclusions, but illness may occur before parasites can be identified, and parasitic inclusions may persist long after illness has resolved. Also, while infection was once considered nearly uniformly fatal, subclinical infections are now recognized. Disease prognosis has improved for many cats through implementation of new therapies, but some pathogens are resistant to these therapies and death from disease is still common. Currently, prevention strategies are limited to ectoparasite control. Cytauxzoonosis caused by Cytauxzoon felis is limited to the Americas, and is especially problematic in southeastern and south central USA. However, other Cytauxzoon species have been recognized in Europe and Asia. This review is aimed at veterinary practitioners and focuses on the diagnosis and treatment of cytauxzoonosis. Disease management is of crucial importance in endemic regions. Furthermore, the expanding geographic range of infection, and the possibility of parasite identification in chronically infected cats with a travel history, make understanding cytauxzoonosis relevant in non-endemic regions as well. The authors draw on evidence from prospective clinical trials, experimental infections, retrospective clinical studies and case reports, as well as their own personal experience with the diagnosis and treatment of cytauxzoonosis. © The Author(s) 2015.

    Bell palsy is largely a diagnosis of exclusion, but certain features in the history and physical examination help distinguish it from facial paralysis due to other conditions: eg, abrupt onset with complete, unilateral facial weakness at 24 to 72 hours, and, on the affected side, numbness or pain around the ear, a reduction in taste, and hypersensitivity to sounds. Corticosteroids and antivirals given within 10 days of onset have been shown to help. But Bell palsy resolves spontaneously without treatment in most patients within 6 months.

    Non-occlusive gut ischaemia is a disease of advanced age. Its causes are reduced cardiac output or shock, facilitated by digitalis, adrenaline, ergotamine and diuretics. The persisting microcirculation and development of gut necrois leads to an increase in certain serum enzymes, such as lactate, LDH and CK-NB. The early application of mesenteric angiography using a DSA technique reveals four grades of under-perfusion. Early and correct diagnosis of the disease should lead to intra-arterial treatment with prostaglandin. In 10 out of 42 cases, conservative therapy led to re-perfusion of the gut. (orig.) [de

    To study the causes, diagnosis and treatment in a case series of binocular diplopia. A retrospective chart review was performed on patients seen in the Diplopia Unit of a tertiary centre during a one-year period. Diplopia was classified as: acute≤1 month since onset; subacute (1-6 months); and chronic (>6 months). Resolution of diplopia was classified as: spontaneous if it disappeared without treatment, partial if the course was intermittent, and non-spontaneous if treatment was required. It was considered a good outcome when diplopia disappeared completely (with or without treatment), or when diplopia was intermittent without significantly affecting the quality of life. A total of 60 cases were included. The mean age was 58.65 years (60% female). An acute or subacute presentation was observed in 60% of the patients. The mean onset of diplopia was 82.97 weeks. The most frequent aetiology was ischaemic (45%). The most frequent diagnosis was sixth nerve palsy (38.3%), followed by decompensated strabismus (30%). Neuroimaging showed structural lesions in 17.7% of the patients. There was a spontaneous resolution in 28.3% of the cases, and there was a good outcome with disappearance of the diplopia in 53.3% at the end of the study. The most frequent causes of binocular diplopia were cranial nerve palsies, especially the sixth cranial nerve, followed by decompensated strabismus. Structural lesions in imaging tests were more than expected. Only one third of patients had a spontaneous resolution, and half of them did not have a good outcome despite of treatment.

    While the Rotterdam criteria look simple and easy to follow, in clinical practice diagnosis of PCOS may be problematic because of the use of inaccurate commercial androgen assays. Progresses in ovarian ultrasound and in AMH measurement have modified the way to make the diagnosis of PCOS and an update of Rotterdam criteria may be necessary. In classic severe form of PCOS, ovarian follicle count is a very reliable diagnostic criterion but AMH measurement may also present high diagnostic specificity and sensitivity. This finding is particularly important when no clinical signs of androgen excess are present and only commercial assays for androgen measurement are available. At the contrary, in mild PCOS phenotypes, sensitivity of AMH measurement is too low whileFNPO count maintains a high diagnostic sensitivity. However, at least in ovulatory hyperandrogenic PCOS phenotype, increased AMH values in association with enlarged ovarian size permit the diagnosis of ovulatory PCOS in 85% of these patients. Treatment of PCOS women has to be directed to get fertility or in patients not seeking fertility to solve or attenuate the psychological implications of androgen excess and of irregular menses and the risk of endometrial hyperplasia. The therapeutic protocols that are used in our department are presented.

    Actinomycosis is an uncommon chronic granulomatous disease that presents as a slowly progressive, indolent, indurated infiltration with multiple abscesses, fistulas, and sinuses. The purpose of this article is to report on a case of actinomycosis with clinical findings similar to periodontitis. A 46-year-old female presented with recurrent throbbing pain on the right first and second molar of the mandible three weeks after root planing. Exploratory flap surgery was performed, and the bluish-gray tissue fragment found in the interproximal area between the two molars was sent for histopathology. The diagnosis from the biopsy was actinomycosis. The clinical and radiographic manifestations of this case were clinically indistinguishable from periodontitis. The patient did not report any symptoms, and she is scheduled for a follow-up visit. The present study has identified periodontitis-mimicking actinomycosis. Actinomycosis should be included in the differential diagnosis in cases with periodontal pain and inflammation that do not respond to nonsurgical treatment for periodontitis. More routine submissions of tissue removed from the oral cavity for biopsies may be beneficial for differential diagnosis.

    Abu Bakr Mohammad Ibn Zakariya Razi, known in the west as Rhazes (865 to 925 AD), was born in the ancient city of Rayy, near Tehran, Iran. He was a renowned physician in medical history and not only followed Hippocrates and Galen, but also greatly extended the analytical approach of his predecessors. Based on the existing documents, he was known as the most distinguished character in the world of medicine up to the 17th century. A great number of innovations and pioneering works in the medical science have been recorded in the name of Rhazes. His fundamental works in urology as part of his research in the realm of medicine have remained unknown. Pathophysiology of the urinary tract, venereal diseases, and kidney and bladder calculi are among his main interests in this field. He also purposed and developed methods for diagnosis and treatment of kidney calculi for the first time in medical history. He also presented a very exact and precise description of neuropathic bladder followed by vertebral fracture. He advanced urine analysis and studied function and diseases of the kidneys. Rhazes recommendations for the prevention of calculi are quite scientific and practical and in accordance with current recommendations to avoid hypercalciuria and increased saturation of urine. Rhazes was not only one of the most important Persian physician-philosophers of his era, but for centuries, his writings became fundamental teaching texts in European medical schools. Some important aspects of his contributions to medicine are reviewed.

    OBJECT Patient outcome measures are becoming increasingly important in the evaluation of health care quality and physician performance. Of the many novel measures currently being explored, patient satisfaction and other subjective measures of patient experience are among the most heavily weighted. However, these subjective measures are strongly influenced by a number of factors, including patient demographics, level of understanding of the disorder and its treatment, and patient expectations. In the present study, patients referred to a neurosurgery clinic for degenerative spinal disorders were surveyed to determine their understanding of lumbar spondylosis diagnosis and treatment. METHODS A multiple-choice, 6-question survey was distributed to all patients referred to a general neurosurgical spine clinic at a tertiary care center over a period of 11 months as a quality improvement initiative to assist the provider with individualized patient counseling. The survey consisted of questions designed to assess patient understanding of the role of radiological imaging in the diagnosis and treatment of low-back and leg pain, and patient perception of the indications for surgical compared with conservative management. Demographic data were also collected. RESULTS A total of 121 surveys were included in the analysis. More than 50% of the patients indicated that they would undergo spine surgery based on abnormalities found on MRI, even without symptoms; more than 40% of patients indicated the same for plain radiographs. Similarly, a large proportion of patients (33%) believed that back surgery was more effective than physical therapy in the treatment of back pain without leg pain. Nearly one-fifth of the survey group (17%) also believed that back injections were riskier than back surgery. There were no significant differences in survey responses among patients with a previous history of spine surgery compared with those without previous spine surgery. CONCLUSIONS These

    This paper reports the activities and the results of the research carried out by the Centers participating to the JSP4 project, within the framework of the EU program on the consequences of the Chernobyl disaster. The project was aimed to develop and to control the application of basic principles for the diagnosis, treatment and follow-up of thyroid carcinoma, with special attention to the peculiar requirement of children and adolescents. To this purpose, training in Western European Centers was offered to a number of scientists from Belarus, Ukraine and Russia. Several official meetings were organized to share views and to discuss the progress of the project. A basic protocol for the diagnosis, treatment and follow-up of thyroid carcinoma has been developed and approved by all participating Centers. Hopefully, it will be applied to the new cases and to those already under monitoring. A large part of the protocol is dedicated to the post-surgical treatment with thyroid hormones for the suppression of TSH and with calcitriol for the management of surgical hypoparathyroidism. A detailed protocol to asses iodine deficiency and, eventually, to introduce a program of iodine supplementation has been proposed. The collection of control cases of childhood thyroid carcinoma in non-radiation exposed European countries has been initiated in Italy, France and Germany. This data will be used as control for the post-Chernobyl childhood thyroid carcinomas. Here is reported a preliminary comparison of the clinical and epidemiological features of almost all (n=368) radiation-exposed Belarus children who developed thyroid carcinoma (age at diagnosis < 16 years), with respect to 90 children of the same age group, who, in the past 20 years, have received treatment for thyroid carcinoma in two centers in Italy (Pisa and Rome). Finally, by molecular biology, genetic mutations of the RET proto-oncogene have been found in several samples of thyroid carcinomas provided by the Belarus

    Full Text Available Infection after total knee replacement (IATJ is a rare complication. It is associated with increased morbidity and mortality increasing the final costs. Gram positive coccus and Staphylococcus coagulase-negative and Staphylococcus aureus are the most common isolated germs (>50% of the cases. Conditions related to the patient, to the surgical procedure and even to the post op have been identified as risk factors to IATJ. Many complementary methods together with clinical symptoms are useful to a proper diagnosis. Treatment for IATJ must be individualized but generally is a combination of systemic antibiotic therapy and surgical treatment. Prosthesis exchange in one or two stages is the first choice procedure. Debridement with prosthesis retention is an option in acute cases with stable implants and antibiotic sensible germs.

    Non-communicable diseases are a public health problem in México. Coronary heart disease and diabetes mellitus are the first and second cause of death in the country, followed by thrombotic cerebrovascular events. Cardiovascular diseases are the leading cause of death; one primary risk factor is hypercholesterolemia. The detection and treatment of lipid abnormalities is the key to the prevention and management of chronic non-communicable diseases. Two nationally representative surveys have shown that lipid abnormalities are the most common risk factors in Mexican adults. The purpose of this guide is to provide a basis for identifying dyslipidemia in a timely manner, and to systematize the criteria for diagnosis and treatment in the first and second level of care.

    Full Text Available Cerebral cavernous malformations are the most common vascular malformations and can be found in many locations in the brain. If left untreated, cavernomas may lead to intracerebral hemorrhage, seizures, focal neurological deficits, or headaches. As they are angiographically occult, their diagnosis relies on various MR imaging techniques, which detect different characteristics of the lesions as well as aiding in planning the surgical treatment. The clinical presentation and the location of the lesion are the most important factors involved in determining the optimal course of treatment of cavernomas. We concisely review the literature and discuss the advantages and limitations of each of the three available methods of treatment—microsurgical resection, stereotactic radiosurgery, and conservative management—depending on the lesion characteristics.

  7. Technology needs for tomorrow's treatment and diagnosis of macular diseases

    Retinal imaging is the basis of macular disease's diagnosis. Currently available technologies in clinical practice are fluorescein and indocyanin green (ICG) angiographies, in addition to optical coherence tomography (OCT), which is an in vivo "histology-like" cross-sectional images of the retina. Recent developments in the field of OCT imaging include Spectral-Domain OCT. However OCT remains a static view of the macula with no direct link with dynamic observation obtained by angiographies. Adaptative optics is an encouraging perspective for fundus analysis in the future, and could be linked to OCT or angiographies. Treatments of macular disease have exploded these past few years. Pharmacologic inhibition of angiogenesis represents a novel approach in the treatment of choroidal neovascularization in eyes with age-related macular degeneration. The major action explored is the direct inhibition of the protein VEGF with antibody-like products. New anti-VEGF drugs are in development aiming at the VEGF receptors or synthesis of VEGF. But various components of the neovascular cascade, including growth factor expression, extracellular matrix modulation, integrin inhibition represent potential targets for modulation with drugs. Intra-vitreal injections are nowadays the main route of administration for these new treatments but they are potentially responsible of side effects such as endophtalmitis. Development of other routes of treatment would require new formulation of used drugs. The improvement of retinal imaging leads to a better understanding of macular disease mechanisms and will help to develop new routes and targets of treatment.

    Full Text Available Objective: To evaluate early and late results of the diagnosis and treatment of children with congenital hydronephrosis. Materials and methods. Conducted diagnosis and treatment of 47 children with hydronephrosis. Comparing the immediate and long6term outcomes in the two groups: primary (n=22 and control (n=25. In the study group vice diagnosed prenatally was exposed using ultrasound diagnostics and MRI. In the control group exhibited diagnosed after hospital survey for recurrent pyelonephritis. Results and discussion. All children performed surgery on the methodology of Andersen—Hines. Duration of external drainage of the urinary tract in the control group was 14–15 days in core — 7–8 days. In 9% of the children performing morphological situation demanded organo6blowing operation. In the late postoperative period in comparison groups differed significantly in the number of recurrent pyelonephritis background of sustained reductions in dilation of the urinary tract and the growth layer parenchymal kidney operated respectively 88% and 75% of the operated patients. Conclusions. Early verification of congenital hydronephrosis affects the outcomes of vice and to prevent deformation of the kidney function and save it. Late diagnosis on the background of persistent urinary tract infections in 9% of cases leads to organo-blowing operation. Persistent infection of the urinary tract is dependent on the timing of postoperative drainage of the kidney. The optimal duration of drainage 7–8 days. Prenatally diagnosed vice number of recurrences of urinary tract infections in the late postoperative period was 8%, and 87% of renal morphometric parameters were approaching the age norm.

    Full Text Available In adults, membranous nephropathy (MN is a major cause of nephrotic syndrome. However, the etiology of approximately 75% of MN cases is idiopathic. Secondary causes of MN are autoimmune diseases, infection, drugs, and malignancy. The pathogenesis of MN involves formation of immune complex in subepithelial sites, but the definite mechanism is still unknown. There are three hypotheses about the formation of immune complex, including preformed immune complex, in situ immune-complex formation, and autoantibody against podocyte membrane antigen. The formation of immune complex initiates complement activation, which subsequently leads to glomerular damage. Recently, the antiphospholipase A2 receptor antibody was found to be associated with idiopathic MN. This finding may be useful in the diagnosis and prognosis of MN. The current treatment includes best supportive care, which consists of the use of angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, lipid-lowering agents, and optimal control of blood pressure. Immunosuppressive agents should be used for patients who suffer from refractory proteinuria or complications associated with nephrotic syndrome. Existing evidence supports the use of a combination of steroid and alkylating agents. This article reviews the epidemiology, pathogenesis, diagnosis, and the treatment of MN.

    The utilization of radioactive sources in medicine, industry and research is associated with a probability of accidental overexposures to ionizing radiation, among which localized irradiation are the most frequent events. Moreover, between 5 and 8 % of the patients undergoing therapeutical irradiations could exhibit a higher individual radiosensitivity which could account for severe skin reactions. Localized overexposures may damage not only epidermis and dermis but also deeper connective tissue, vessels, muscles and even bones. Within the framework of a cooperation agreement between the Buenos Aires Burn Hospital and the National Board of Nuclear Regulation, a Radio pathology Committee has been established in 1997 with the purpose of carrying out a collaborative project concerning diagnosis and treatment of radiological burns. The present document particularly considers radiological burns form the point of view of their physiopathology, physical and biological dosimetry, diagnosis prognosis and treatment. It also includes basic concepts of radiation biology and radio pathology. It could be an useful tool for training medical practitioners and also a practical guidance for organizing medical response in accidental overexposures. (author)

    Amongst all cancer subtypes, gastrointestinal tumours are responsible for most cancer-related deaths. In most of the cases, the limitation of the prognosis of patients with malignant gastrointestinal tumours can be attributed to delayed diagnosis of the disease. In the last decade, secondary prevention strategies, in particular tumour screenings, have been identified to significantly improve the identification of patients with early-stage disease, leading to more effective therapeutic interventions. Therefore, new screening methods and further innovative treatment approaches may lead to an increase in progression-free and overall survival rates. Exosomes are small microvesicles with a size of 50-150 nm. They are formed in the endosomal system of many different cell types, where they are packed with nucleotides and proteins from the parental cell. After their release into the extracellular space, exosomes can deliver their cargo into recipient cells. By this mechanism, tumour cells can recruit and manipulate the adjacent and systemic microenvironment in order to support invasion and dissemination. Cancer-derived exosomes in the blood may provide detailed information about the tumour biology of each individual patient. Moreover, tumour-derived exosomes can be used as targetable factors and drug delivery agents in clinical practice. In this review, we summarise new aspects about novel implications in the diagnosis and treatment of gastrointestinal cancer and show how circulating exosomes have come into the spotlight of research as a high potential source of 'liquid biopsies'.

    Full Text Available Dizziness is one of the common reasons for visits to physicians of various specialties; the data of foreign investigations show that benign paroxysmal positional vertigo (BPPV is most frequently encountered.Objective: to study the causes of dizziness, to analyze the frequency of BPPV and the efficiency of its treatment in outpatient practice.Patients and methods. The investigation enrolled 80 patients, including 55 (68.7% women and 25 (31.3% men, aged 18 to 75 years (mean age 53.8±12.8 years, who complained of dizziness and sought for medical advice in the Therapeutic-and-Diagnostic Unit, A.Ya. Kozhevnikov Clinic of Nervous System Diseases, I.M. Sechenov First Moscow State Medical University.Results. The most common causes of dizziness in outpatient practice were BPPV (46.2% and postural phobic vertigo (35%. The diagnosis of VPPV, if special positional testing (Dix-Hallpike and McClure-Pagnini tests was carried out, was shown to create no significant difficulties. The diagnosis was not established in the majority (97.5% of the patients; effective treatment was performed in one of the patients. Combined treatment, by performing the positional tests and using betaserc for 2 months, led to complete resolution of positional vertigo in most (97.3% patients.Discussion. The findings indicate the efficiency of examining patients with complaints of dizziness, by using the special otoneurological tests to detect BPPV. The purposeful questioning of patients with BPPV can suspect this disease in the majority of cases. Our investigation shows the high efficiency of rehabilitation maneuvers for BPPV, which agrees well with the data of other authors. Physicians’ poor awareness of BPPV among physicians and the high efficiency of its treatment in outpatient practice are noted.

    Full Text Available ABSTRACT Cystic fibrosis (CF is an autosomal recessive genetic disorder characterized by dysfunction of the CFTR gene. It is a multisystem disease that most often affects White individuals. In recent decades, various advances in the diagnosis and treatment of CF have drastically changed the scenario, resulting in a significant increase in survival and quality of life. In Brazil, the current neonatal screening program for CF has broad coverage, and most of the Brazilian states have referral centers for the follow-up of individuals with the disease. Previously, CF was limited to the pediatric age group. However, an increase in the number of adult CF patients has been observed, because of the greater number of individuals being diagnosed with atypical forms (with milder phenotypic expression and because of the increase in life expectancy provided by the new treatments. However, there is still great heterogeneity among the different regions of Brazil in terms of the access of CF patients to diagnostic and therapeutic methods. The objective of these guidelines was to aggregate the main scientific evidence to guide the management of these patients. A group of 18 CF specialists devised 82 relevant clinical questions, divided into five categories: characteristics of a referral center; diagnosis; treatment of respiratory disease; gastrointestinal and nutritional treatment; and other aspects. Various professionals working in the area of CF in Brazil were invited to answer the questions devised by the coordinators. We used the PubMed database to search the available literature based on keywords, in order to find the best answers to these questions.

    Maturity onset diabetes of the young (MODY) designates monogenic forms of non-autoimmune diabetes characterised by autosomal dominant inheritance, non-insulin dependent diabetes at onset and diagnosis often before 25 years of age. MODY constitutes genetically and clinically heterogeneous forms...... of diabetes. More than 8 different genes are known to cause MODY, among which hepatocyte nuclear factor 1 alpha (HNF1A) (MODY3) and glucokinase (GCK) (MODY2) mutations are the most common. Both forms of MODY are characterised by specific beta cell dysfunction, with patients with HNF1A-diabetes having...... a reduced insulin secretory capacity, while patients with GCK-diabetes have a glucose-sensing defect, but preserved insulin secretory capacity. Patients with MODY are effectively treated with sulphonylurea (SU) due to very high sensitivity to these drugs, but they are also prone to develop hypoglycaemia...

An early stage melanoma can be surgically removed, with a survival rate of 99%. However, metastasized melanoma is difficult to cure. The 5-year survival rates for patients with metastasized melanoma are still below 20%. Metastasized melanoma is currently treated by chemotherapy, targeted therapy, immunotherapy and radiotherapy. The outcome of most of the current therapies is far from optimistic. Although melanoma patients with a mutation in the oncogene v-Raf murine sarcoma viral oncogene homolog B1 (BRAF have an initially higher positive response rate to targeted therapy, the majority develop acquired drug resistance after 6 months of the therapy. To increase treatment efficacy, early diagnosis, more potent pharmacological agents, and more effective delivery systems are urgently needed. Nanotechnology has been extensively studied for melanoma treatment and diagnosis, to decrease drug resistance, increase therapeutic efficacy, and reduce side effects. In this review, we summarize the recent progress on the development of various nanoparticles for melanoma treatment and diagnosis. Several common nanoparticles, including liposome, polymersomes, dendrimers, carbon-based nanoparticles, and human albumin, have been used to deliver chemotherapeutic agents, and small interfering ribonucleic acids (siRNAs against signaling molecules have also been tested for the treatment of melanoma.

    Woolf, Clifford J

    2011-03-01

    Nociceptor inputs can trigger a prolonged but reversible increase in the excitability and synaptic efficacy of neurons in central nociceptive pathways, the phenomenon of central sensitization. Central sensitization manifests as pain hypersensitivity, particularly dynamic tactile allodynia, secondary punctate or pressure hyperalgesia, aftersensations, and enhanced temporal summation. It can be readily and rapidly elicited in human volunteers by diverse experimental noxious conditioning stimuli to skin, muscles or viscera, and in addition to producing pain hypersensitivity, results in secondary changes in brain activity that can be detected by electrophysiological or imaging techniques. Studies in clinical cohorts reveal changes in pain sensitivity that have been interpreted as revealing an important contribution of central sensitization to the pain phenotype in patients with fibromyalgia, osteoarthritis, musculoskeletal disorders with generalized pain hypersensitivity, headache, temporomandibular joint disorders, dental pain, neuropathic pain, visceral pain hypersensitivity disorders and post-surgical pain. The comorbidity of those pain hypersensitivity syndromes that present in the absence of inflammation or a neural lesion, their similar pattern of clinical presentation and response to centrally acting analgesics, may reflect a commonality of central sensitization to their pathophysiology. An important question that still needs to be determined is whether there are individuals with a higher inherited propensity for developing central sensitization than others, and if so, whether this conveys an increased risk in both developing conditions with pain hypersensitivity, and their chronification. Diagnostic criteria to establish the presence of central sensitization in patients will greatly assist the phenotyping of patients for choosing treatments that produce analgesia by normalizing hyperexcitable central neural activity. We have certainly come a long way since the

We performed a systematic review of how much has been produced in research published online and on print regarding ROP in different settings around the world. Early Treatment for ROP (ETROP) classification is the currently accepted classification of ROP. Fluorescein angiography and spectral domain optical coherence tomography (SD-OCT) may eventually lead to changes in the definition of ROP, and as a consequence, they will serve as a guide for treatment. Intravitreal anti-VEGF therapy has proven to be more effective in terms of lowering recurrence, allowing growth of the peripheral retina, and diminishing the incidence of retinal detachment when proliferative ROP is diagnosed. Whether anti-VEGF plus laser are better than any of these therapies separately remains a subject of discussion. Telemedicine is evolving everyday to allow access to remote areas that do not count with a retina specialist for treatment. A management algorithm is proposed according to our reference center experience. ROP is an evolving subject, with a vulnerable population of study that, once treated with good results, leads to a reduction in visual disability and in consequence, in a lifetime improvement.

    Incidence and mortality rates of cancer are currently on the top of disease pattern and the number is increasing and increasing worldwide. The impact of screening program for early diagnosis has been proved their important roles in the war against cancer because it helps increase the cure rates, decrease the mortality and morbidity rates, and therefore reduces the economic-social burden. Advances in diagnostic imaging techniques, especially the hybrid imaging (X-ray and Nuclear Medicine) such as PET/CT, SPECT/CT, PET/MRI, is important in accurate staging and these help choose the optimized treatment options to prolong survival while improve the quality of life. The treatment outcomes of cancer has certain remarkable advances based on variety of research to modify, promote and strengthen the traditional treatments (surgery-chemotherapy-radiation) such as laparoscopic surgery, combined chemo-regimens, intensity modulated radiation therapy, volumetric modulated arc therapy, stereotactic radiation therapy, radio surgery, PET/CT simulation, radioactive seeds implant, selective internal radiation therapy, intra-operative radiation therapy, etc. as well as the emerge of new methods such as targeted therapy, immune therapy, radio immunotherapy, proton therapy and heavy ion. Treatment of cancer is now the “individualized treatment” with the advances of biochemistry and histopathology. To achieve the most optimal outcomes, cancer should be approached by a multi professional team including biochemistry, immunology, histopathology, surgical oncology, medical oncology and radiation oncology.

    Full Text Available to improve treatment results in premature infants with neonatal respiratory distress syndrome (NRDS, by establishing developmental mechanisms and elaborating methods for its early diagnosis, treatment, and prevention. Material and methods. The paper analyzes the results of a clinical observation and laboratory, instrumental, immunological, morphological, and radiological studies of 320 premature neonates at 26—35 weeks gestational age. The following groups of neonates were identified: 1 40 premature neonatal infants without NRDS and with the physiological course of an early neonatal period (a comparison group; 2 190 premature neonates with severe NRDS in whom the efficiency of therapy with exogenous surfactants, such as surfactant BL versus curosurf, was evaluated; 3 90 premature newborn infants who had died from NRDS at its different stages. Results. The poor maternal somatic, obstetric, and gynecological histories in the early periods of the current pregnancy create prerequisites for its termination, favor the development of severe acute gestosis, and cause abnormal placental changes. Each gestational age is marked by certain placental changes that promote impaired uterineplacentalfetal blood flow and premature birth. Alveolar and bronchial epithelial damages, including those ante and intranatally, microcircula tory disorders play a leading role in the tanatogenesis of NRDS. Intranatal hypoxia and amniotic fluid aspiration are one of the important factors contributing to alveolar epithelial damage and NRDS in premature neonates. Exogenous surfactants prevent the development of hyaline membranes and are useful in the normalization of ventilation-perfusion relationships and lung biomechanical properties. Conclusion. This study could improve the diagnosis and treatment of NRDS, which assisted in reducing the duration of mechanical ventilation from 130±7.6 to 65±11.6 hours, the number of complications (the incidence of intragastric

    Full Text Available Spine injuries in children are of great social significance. Currently, the incidence of spinal cord injuries in children has increased; this is due to the use of modern imaging devices (digital X-ray examination, CT, MRI at the prehospital and hospital stages. For children, compression fractures of the vertebral body, which are associated with serious injuries to the musculoskeletal system, are more characteristic. Compression fractures of vertebral bodies (1–2 % with improper treatment can lead to aseptic necrosis of the vertebra, kyphoscoliosis and other pathological conditions, which often results in disability. When X-ray diagnosis of fractures of transverse and spinous processes, one should consider additional ossification points, which can be mistaken for fractures. Also, differential diagnosis should take into account congenital wedge vertebrae and other abnormalities of vertebral development, which can be mistaken for fractures. The publication presents the results of a comprehensive examination and treatment of 85 children with spine trauma. The age of the examined was from 3 months to 16 years. In 20 cases, we detected compression fractures of the spine at different levels (cervical – 1, upper-thoracic – 4, medium-thoracic – 10, lower-thoracic – 2, lumbar – 3. In 25 cases, a rotational subluxation of the C I vertebra was diagnosed, in 3 – a traumatic rupture of the intervertebral disc, in 29 – a fracture of the coccyx. Complicated injuries of the spine accompanied by lesions of the spinal cord and roots were noted in 7 patients. Given the anatomical and physiological features of spine injuries in children, conservative methods of treatment were predominantly used.

    Full Text Available Context Bariatric surgery has proven to be the most effective method of treating severe obesity. Nevertheless, the acceptance of bariatric surgery is still questioned. The surgical complications observed in the early postoperative period following surgeries performed to treat severe obesity are similar to those associated with other major surgeries of the gastrointestinal tract. However, given the more frequent occurrence of medical comorbidities, these patients require special attention in the early postoperative follow-up. Early diagnosis and appropriate treatment of these complications are directly associated with a greater probability of control. Method The medical records of 538 morbidly obese patients who underwent surgical treatment (Roux-en-Y gastric bypass surgery were reviewed. Ninety-three (17.2% patients were male and 445 (82.8% were female. The ages of the patients ranged from 18 to 70 years (average = 46, and their body mass indices ranged from 34.6 to 77 kg/m2. Results Early complications occurred in 9.6% and were distributed as follows: 2.6% presented bleeding, intestinal obstruction occurred in 1.1%, peritoneal infections occurred in 3.2%, and 2.2% developed abdominal wall infections that required hospitalization. Three (0.5% patients experienced pulmonary thromboembolism. The mortality rate was 0,55%. Conclusion The incidence of early complications was low. The diagnosis of these complications was mostly clinical, based on the presence of signs and symptoms. The value of the clinical signs and early treatment, specially in cases of sepsis, were essential to the favorable surgical outcome. The mortality was mainly related to thromboembolism and advanced age, over 65 years.

    "Globus sensation" is often described as the sensation of a lump in the throat associated with dry swallowing or the need for dry swallowing, which disappears completely during eating or drinking and for which no organic cause can be established. Due to the uncertain etiology of "globus sensation", it remains difficult to establish standard treatment strategies for affected patients. Lately most attention has been focused on gastroesophageal reflux disease and several reports have indicated that there is a close relationship between esophageal acid reflux and globus sensation. Nowadays, empirical therapy with a high dose of a proton pump inhibitor (PPI) is considered to be indicated for patients with globus sensation, after excluding organic diseases such as pharyngeal cancer, Zenker's diverticulum, or thyroid enlargement. If patients are nonresponsive to PPI therapy, evaluation of esophageal motility should be done. In our recent study, 47.9% had abnormal esophageal motility, with the most common esophageal motility abnormality being an ineffective esophageal motility in PPI-resistant patients with globus sensation. This suggests that prokinetics alone or adding prokinetics to PPI should be the treatment to be considered, although few studies have investigated the efficacy of prokinetics in the treatment of patients with globus sensation. If patients without any esophageal motility dysfunctions are nonresponsive to PPI therapy, either cognitive-behavioral therapy, anti-depressants, or gabapentin could be helpful, although further well-designed, randomized controlled large-scale studies will be necessary to determine the effectiveness of each treatment strategy on patients with globus sensation.

    2016-01-01

    A vesicouterine fistula is a rare form of urogenital fistula, yet there is increasing prevalence in the United States because of the rising rate of cesarean deliveries. Vesicouterine fistulas have various presentations including menouria, hematuria, or urinary incontinence. A 39-year-old multiparous woman presented with urine leakage after her third cesarean delivery. She had been treated for mixed urinary incontinence with overactive bladder medications and a midurethral sling with continued complaints of urine leakage. The patient noticed her symptoms of urine leakage improved during menses when she used a menstrual cup. After confirmation of vesicouterine fistula, the patient underwent robotic-assisted surgery and her symptoms of insensible urine leakage resolved. When evaluating women with urinary incontinence and a history of cesarean deliveries, use of menstrual cup may aid in the diagnosis of vesicouterine fistula. Robotic-assisted laparoscopic repair with tissue interposition flap is an efficacious minimally invasive method for treatment of vesicouterine fistula.

    Full Text Available Background: Fractures of the capitellum are rare injuries of the elbow usually seen in the adolescents. This fracture is often missed in the emergency room if a proper radiograph is not available. Recent reports have described many modalities of treatment favoring headless screw for fixation. The facility for headless screw fixation, however, is not available in most centers. This paper presents the diagnosis and management of type 4 capituller fractures (Mckee with gadgets available in a district hospital. Materials and Methods: Between 2004 and 2007 three patients with right sided type IV capetullar fracture were treated in a district hospital. There were two boys aged 15 and 17 and one 33 years old lady. In one case, the fracture was missed in the emergency room. A double arc sign in the lateral views of the X-rays of the elbow was seen in all the cases. In each case a preoperative CT scan was done and a diagnosis of Mckee type IV fracture of the capitellum was made. Under tourniquet, using extended lateral approach, open reduction and internal fixation was done using 4mm partially threaded AO cancellous screws (n=2 and 2.7 mm AO screws (n=1, under vision from posterior to anterior direction from the posterior aspect of lateral condyle of humerus avoiding articular penetration. Results: All the fractures united uneventfully. At the end of one year follow-up, two cases had excellent elbow function; implants were removed and there were no signs of AVN or arthritis. The third case had good elbow ROM at 11 months without AVN. Conclusion: Double arc sign on lateral X-rays of the elbow along with pre-operative CT scan evaluation is important to avoid a missed diagnosis and analysis of type IV capitellur fracture. Fixation with non-cannulated ordinary AO screws using extended Kocher′s lateral approach has given good results.

  7. Difficulties in diagnosis and treatment of Paget’s disease

    Full Text Available Paget’s disease is a rare finding in Poland. It is a disorder of the osteoarticular system, which, in adults, mostly affects people over 55 years of age. The clinical picture varies, depending on the location of the lesions, making the diagnosis difficult, sometimes taking many years for a correct diagnosis to be made. In etiopathogenesis, genetic predispositions as well as viral infections play an important role. From the genetic point of view, Paget’s disease is heterogeneous, as numerous mutations are known, and the genotype to phenotype relationship is unclear. The first phase of the disease is characterized by an increased osteocytes activity, due to morphologically changed and RANKL overstimulated osteocytes. This leads to an intensification of ossification processes that occur in a chaotic manner. Therefore, the resulting bone is weak, extensively vascularized and there is an increased risk of fracture or deformity. Clinical manifestations of Paget’s disease might include pain, excessive warmth, bone deformations, degenerative lesions in the adjacent joints, compression of the neural structures, hearing loss, and dilated cardiomiopathy. Other possible complications include the development of benign and malignant bone tumors and hypercalcaemia in the case of immobilization. An elevated level of serum alkaline phosphatase, bone x-ray and bone scintigraphy are crucial in making the diagnosis. The disease should be distinguished from osteomalacia, osteoporosis, hyperparathyroidism and multiple myeloma. Bisphosphonates at doses higher than those applied for osteoporosis are an effective treatment. The occurrence of orthopedic, neurological and laryngological complications is often a reason for surgical intervention.

    2015-01-01

    Hepatocellular carcinoma (HCC) is ranked as the 5th common type of cancer worldwide and is considered as the 3rd common reason for cancer-related deaths. HCC often occurs on top of a cirrhotic liver. The prognosis is determined by several factors; tumour extension, alpha-fetoprotein (AFP) concentration, histologic subtype of the tumour, degree of liver dysfunction, and the patient’s performance status. HCC prognosis is strongly correlated with diagnostic delay. To date, no ideal screening modality has been developed. Analysis of recent studies showed that AFP assessment lacks adequate sensitivity and specificity for effective surveillance and diagnosis. Many tumour markers have been tested in clinical trials without progressing to routine use in clinical practice. Thus, surveillance is still based on ultrasound (US) examination every 6 mo. Imaging studies for diagnosis of HCC can fall into one of two main categories: routine non-invasive studies such as US, computed tomography (CT), and magnetic resonance imaging, and more specialized invasive techniques including CT during hepatic arteriography and CT arterial portography in addition to the conventional hepatic angiography. This article provides an overview and spotlight on the different diagnostic modalities and treatment options of HCC. PMID:26140083

    Our objective was to develop a guide based on the best available evidence that allow family physicians to establish criteria for screening, diagnosis, prevention, treatment of disease, early detection and management of complications; to standardize the organizing processes of the diabetic patient's care in the primary care level; and to achieve lifestyle modification for patients and promote self-care. Clinical questions were stated according to the diagram and structured patient-intervention-comparison-outcome. We used a mixed methodology-adoption adjustment, and include 32 guides. For recommendations not included in these, the search process was conducted in PubMed and Cochrane Library Plus with these terms: diabetes mellitus type 2, epidemiology, detection and diagnosis, classification, drug therapy, effects, prevention, control and complication. The clinical practice guideline emphasizes the fundamental change in lifestyle (diet and exercise), self-care and proactive participation of the patient, in addition to the dynamic prescription of medications that would achieve metabolic control in order to reduce late complications.

    Objective: To evaluate the diagnosis, safety and efficacy of interventional therapy and surgery for child traumatic intracranial aneurysms. Methods: Five patients with traumatic intracranial aneurysms including three males and two females, age ranged from 2 to 10 years old; 5 had undertaken CT and MR scanings. All of them showed traumatic subarachnoid hemorrhage in 2, intracerebral hematoma in the right occipital and the left temporal respectively in 2 and another one with somewhat bleeding at the posterior fossa and right trigone of lateral ventricles and subdural bleeding at the tentorium edge. The detailed vascular involvement diagnosis were made by DSA revealing one of left C1 segmental internal carotid artery traumatic aneurysm, one of the branch of right sylvian artery traumatic aneurysm, one of left middle cerebral artery traumatic aneurysm, one of left posterior cerebral artery traumatic aneurysm, one of the branch of right posterior inferior cerebellar artery traumatic aneurysm. Two of them were treated by embolization therapy with CDC and two by surgery. Results: The CDC embolization in 2 cases and the surgical operation for another 2 were all succeeded without death or complications. The last case was followed up closely. Conclusions: Traumatic intracranial aneurysm is rare in childhood but endovascular treatment with CDC and surgery is efficient and safe, yet the long-term efficacy is still relied on follow-up.

    Full Text Available The purpose of this review was to demonstrate the definition of the original symptom (OS and how it works in medical procedures as to the Sasang medicine based on the Jema Lee's Donguisusebowon (Longevity and Life Preservation in Eastern Medicine. OS is defined as the sum of all clinical information featured by an individual's intrinsic characteristics as Sasangin and health state prior to onset. It is the key factor in the clinical application of Sasang medicine including the diagnosis of constitutional type and Sasang symptomatology because the imbalance of metabolic functions of each Sasangin originates from that. The working principles of the OS and Sasang symptomatology can be summarized as follows. First, clinical information regarding cold or heat intolerance determines the cold or heat pattern of Sasang symptomatology. Another is the present worsening of the severity of Sasang symptomatology by one level as compared with that in the past. Symptoms prior to the onset worsen to a higher level of severity after any disorder breaks out. Finally, the treatment strategy and progress of each Sasangin are determined following the characteristics of the OS. Theoretical and clinical studies should be conducted to show the specific criteria for the diagnosis of Sasang symptomatology in the future.

    The potential importance of both prevention and personal responsibility in controlling heart disease, the leading cause of death in the USA and elsewhere, has attracted renewed attention. Coronary artery disease is preventable, using relatively simple and inexpensive lifestyle changes. The inexorable rise in the prevalence of obesity, diabetes, dyslipidemia, and hypertension, often in the risk cluster known as the metabolic syndrome, drives the ever-increasing incidence of heart disease. Population-wide improvements in personal health habits appear to be a fundamental, evidence based public health measure, yet numerous barriers prevent implementation. A common symptom in patients with coronary artery disease, classical angina refers to the typical chest pressure or discomfort that results when myocardial oxygen demand rises and coronary blood flow is reduced by fixed, atherosclerotic, obstructive lesions. Different forms of angina and diagnosis, with a short description of the significance of pain and silent ischemia, are discussed in this review. The well accepted concept of myocardial oxygen imbalance in the genesis of angina is presented with new data about clinical pathology of stable angina and acute coronary syndromes. The roles of stress electrocardiography and stress myocardial perfusion scintigraphic imaging are reviewed, along with the information these tests provide about risk and prognosis. Finally, the current status of gender disparities in heart disease is summarized. Enhanced risk stratification and identification of patients in whom procedures will meaningfully change management is an ongoing quest. Current guidelines emphasize efficient triage of patients with suspected coronary artery disease.

    There is still no reliable biomarker for the diagnosis of pancreatic adenocarcinoma. Carbohydrate antigen 19-9 (CA 19-9) is a tumor marker only recommended for pancreatic adenocarcinoma follow-up. One of the clinical problems lies in distinguishing between this cancer and other benign pancreatic diseases such as chronic pancreatitis. In this study we will assess the value of panels of serum molecules related to pancreatic cancer physiopathology to determine whether alone or in combination could help to discriminate between these two pathologies. CA 19-9, carcinoembryonic antigen (CEA), C-reactive protein, albumin, insulin growth factor-1 (IGF-1) and IGF binding protein-3 were measured using routine clinical analyzers in a cohort of 47 pancreatic adenocarcinoma, 20 chronic pancreatitis and 15 healthy controls. The combination of CA 19-9, IGF-1 and albumin resulted in a combined area under the curve (AUC) of 0.959 with 93.6% sensitivity and 95% specificity, much higher than CA 19-9 alone. An algorithm was defined to classify the patients as chronic pancreatitis or pancreatic cancer with the above specificity and sensitivity. In an independent validation group of 20 pancreatic adenocarcinoma and 13 chronic pancreatitis patients, the combination of the four molecules classified correctly all pancreatic adenocarcinoma and 12 out of 13 chronic pancreatitis patients. Although this panel of markers should be validated in larger cohorts, the high sensitivity and specificity values and the convenience to measure these parameters in clinical laboratories shows great promise for improving pancreatic adenocarcinoma diagnosis.

    Dermatomyositis (DM), polymyositis (PM), necrotizing myopathy (NM) and inclusion body myositis (IBM) are four distinct subtypes of idiopathic inflammatory myopathies - in short myositis. Recent studies have shed some light on the unique pathogenesis of each entity. Some of the clinical features are distinct, but muscle biopsy is indispensable for making a reliable diagnosis. The use of magnetic resonance imaging of skeletal muscles and detection of myositis-specific autoantibodies have become useful additions to our diagnostic repertoire. Only few controlled trials are available to substantiate current treatment approaches for myositis and hopes are high that novel modalities will become available within the next few years. In this review we provide an up-to-date overview of the pathogenesis and diagnostic approach of myositis. We aim to present a guide towards therapeutic and general management. © 2013 British Society for Immunology.

    Directory of Open Access Journals (Sweden)

    G. V. Ponomarev

    2018-01-01

    Full Text Available Vascular myelopathy is a rare severe disease caused by a broad spectrum of causes, among which pathology of the aorta and its branches, aortic surgery, spinal diseases, and spinal trauma occupy the main place. The processes of neuroinflammation and glutamate neurotoxicity play a leading role in the pathogenesis of myeloischemia. The clinical picture of the disease is nonspecific and depends on the location and volume of an ischemic focus. Magnetic resonance imaging is a gold standard for diagnosis. However, this method remains insensitive in the acute period and fails to detect spinal cord ischemia at preclinical stages. The investigation and introduction of specific biochemical markers (glutamate receptors and their antibodies for neurotoxicity, which can identify ischemia in the advanced stage and predetermine its development, are promising. The treatment of vascular myelopathy has not currently been standardized and it is mainly pathogenetic and symptomatic.

    Full Text Available Angela Di Cesare, Donato Traversa Faculty of Veterinary Medicine, University of Teramo, Teramo, Italy Abstract: Angiostrongylus vasorum is a parasitic nematode affecting the heart and pulmonary arteries of wild (eg, foxes and domestic canids. The parasite has an indirect life cycle in which slugs and snails act as intermediate hosts. In the last few years the parasite has spread outside the traditional endemic foci, and there is a rise of documented cases of canine angiostrongylosis across Europe. Angiostrongylus vasorum causes cardiopulmonary disorders and coagulopathies, along with different nonspecific clinical signs. Fatal infections are frequently reported. Given the severity of the infection and the recent geographic spreading of the parasite, this article reviews and discusses the current knowledge of A. vasorum, with a special focus on recent insights on diagnosis, prevention, and treatment of dog angiostrongylosis.

    2011-07-01

    The paper presents the diagnosis, treatment and monitoring of microbial influenced corrosion (MIC) in long oil pipelines. The presence of inorganic solids, bacteria, gases and organic acids in produced water in the oil pipelines causes MIC, which is hard to detect or test and it does not produce any unique type of corrosion. Chemical analysis of water from pig runs is presented in a tabular form and a graphical analysis of pig sludge solids is shown. From the biometabolite analysis, 23 putative hydrocarbon biometabolites were identified and biometabolites for the anaerobic biodegradation of aromatic HC were also detected. Operational considerations include the history of MIC in upstream pipelines, water slugging, and presence of suspended solids, among others. From microbiological, chemical, metallurgical and operational evidence it was suggested that MIC is a likely mechanism. The mitigation program is described and suggestions for successful mitigation measures include removal of oxygen sources, scale inhibitor injection, and increasing CO2 inhibitor concentration.

    Full Text Available Subacromial impingement syndrome (SIS is a very common cause of shoulder pain in the young adults. It can cause debilitating pain, dysfunction, and affects the activities of daily living. It represents a spectrum of pathology ranging from bursitis to rotator cuff tendinopathy which can ultimately lead to degenerative tear of the rotator cuff. Various theories and concepts have been described and it is still a matter of debate. However, most published studies suggest that both extrinsic and intrinsic factors have a role in the development of SIS. The management is controversial as both nonoperative and operative treatments have shown to provide good results. This article aims to provide a comprehensive current concepts review of the pathogenesis, etiologies, clinical diagnosis, appropriate use of investigations, and discussion on the management of SIS.

    Hodgkin's lymphoma has been traditionally defined as a hematopoietic neoplasm composed of diagnostic Reed-Sternberg cells. More than 70% of the cases involve cervical or supraclavicular lymph nodes. Isolated sub-diaphragmatic lymphadenopathy or organ involvement is rare. We present the case of Hodgkin's lymphoma in a 51 years old female, who presented with obstructive jaundice and lymphadenopathy, empirically treated previously as a case of tuberculosis. Chemotherapy with modified ABVD protocol was given with dose modification according to LFT's. Her liver functions returned to normal levels after the first cycle. The main purpose of reporting the case is to stress definitive diagnosis of the disease before initiating treatment and the modified chemotherapy regimen used in this infrequent presentation of the disease.

    To study causes of vertigo in hypertensive patients and specify approaches to its treatment. Material and methods. Prevalence and causes of vertigo were analysed in 285 patients with arterial hypertension (AH). The examination included 24-h monitoring of arterial pressure (APM) and MR-tomography of the head. The majority of patients (78%) hospitalized with the diagnosis "hypertensive crisis" were diagnosed to have other diseases (headaches of tension, stroke, Meniere's syndrome and disease, etc.) the development of which was accompanied with hypertension and simulated a hypertensive crisis. Vertigo occurs in 20% hypertensive patients and is unrelated to elevated blood pressure. It is rather due to associated neurological, peripheral vestibular and other diseases. APM shows that vertigo occurs in hypotension after intake of hypotensive drugs. In hypertensive patients treatment of vertigo should not be directed only to management of elevated pressure but demands treatment of underlying disease. Vertigo plus mnestic disorders are effectively corrected with tanakan in a dose 120-160 mg/day. Vertigo in hypertensive patients is not caused by elevated pressure but related with concomitant neurological or peripheral vestibular diseases as well as hypotension. Hypertensive patients with vertigo need correction of the condition causing it.

    Full Text Available Abstract This review article focuses on the various aspects of translational research, where research on human subjects can ultimately enhance the diagnosis and treatment of future patients. While we will use specific examples relating to the asbestos related cancer mesothelioma, it should be stressed that the general approach outlined throughout this review is readily applicable to other diseases with an underlying molecular basis. Through the integration of molecular-based technologies, systematic tissue procurement and medical informatics, we now have the ability to identify clinically applicable "genotype"-"phenotype" associations across cohorts of patients that can rapidly be translated into useful diagnostic and treatment strategies. This review will touch on the various steps in the translational pipeline, and highlight some of the most essential elements as well as possible roadblocks that can impact success of the program. Critical issues with regard to Institutional Review Board (IRB and Health Insurance Portability and Accountability Act (HIPAA compliance, data standardization, sample procurement, quality control (QC, quality assurance (QA, data analysis, preclinical models and clinical trials are addressed. The various facets of the translational pipeline have been incorporated into a fully integrated computational system, appropriately named Dx2Tx. This system readily allows for the identification of new diagnostic tests, the discovery of biomarkers and drugable targets, and prediction of optimal treatments based upon the underlying molecular basis of the disease.

    2015-12-15

    Lymphogranuloma venereum (LGV) has emerged as an important cause of proctitis and proctocolitis in men who have sex with men; classical inguinal presentation is now increasingly uncommon. We report summary findings of an extensive literature review on LGV clinical presentation, diagnosis, and treatment that form the evidence base for the 2015 Centers for Disease Control and Prevention treatment guidelines for sexually transmitted diseases. Proctitis and proctocolitis are now the most commonly reported clinical manifestations of LGV, with symptoms resembling those of inflammatory bowel disease. Newer molecular tests to confirm LGV infection are sensitive and specific, but are generally restricted to research laboratory or public health settings. Doxycycline (100 mg twice daily for 21 days) remains the treatment of choice for LGV. Patients with rectal chlamydial infection and signs or symptoms of proctitis should be tested for LGV, or if confirmatory testing is not available, should be treated empirically with a recommended regimen to cover LGV infection. © The Author 2015.

  7. Pompe Disease: Early Diagnosis and Early Treatment Make a Difference

    2013-08-01

    Full Text Available Pompe disease (glycogen storage disease type II or acid maltase deficiency is a lysosomal disorder in which acid α-glucosidase (GAA deficiencies lead to intralysosomal accumulation of glycogen in all tissues; most notably in skeletal muscles. Both the patient's age at the onset of Pompe disease symptoms and the rate of deterioration caused by the disease can vary considerably. In classical infant-onset Pompe disease (IOPD, symptoms start very early in life, and death occurs soon afterward if the disease remains untreated. In later-onset Pompe disease, symptoms are slower to appear, and patients often progress to wheelchair confinement and eventual respiratory failure. A diagnosis can be made by screening for GAA in dried blood samples, followed either by GAA assessment in lymphocytes or in fibroblasts or by the genetic analysis of mutations. Treatment by enzyme replacement therapy (ERT with alglucosidase alfa was approved for human use in 2006. In classical IOPD, treatment significantly lengthens survival and improves motor development and cardiac function. The sooner ERT begins, the better are the results. Newborn screening aims to take advantage of different technologies for diagnosing and treating newborns early on and it yields better outcomes. However, newborns diagnosed early and other long-term survivors may encounter fresh problems, making up a new phenotype of IOPD patients. Further modifications of the treatment, such as a decrease in immune responses to ERT, a higher dosage, a better uptake formulation, and gene therapy delivered locally or systemically are being explored.

    The aims of the studies included in this thesis were: - to investigate the reliability of 201 Thallium single photon emission computed tomography. Tl SPECT for preoperative diagnosis and histological staging of malignant astrocytomas in comparison with CT; - to develop a method for quantification of cerebral thallium uptake, and to evaluate the quantitative measurement in comparison with CT, for astrocytoma treatment follow-up purposes; - to compare quantitative Tl SPECT and proton magnetic resonance spectroscopy (H-MRS) with conventional MR imaging for astrocytoma monitoring, and to evaluate associations between change of morphological tumour characteristics during treatment and changes of cerebral thallium uptake and metabolic ratios. Results and conclusions: - High TI-index, calculated as a ratio comparing tumour uptake to uptake in the contralateral hemisphere, is an indicator of highly malignant astrocytoma. Differentiation between the high-grade astrocytomas, the low-grade astrocytomas, and infectious lesions is only partial, with an overlap of Tl-indexes between these groups. High-grade astrocytomas that do not show contrast enhancement on CT, and astrocytomas with central necrosis and moderate ring-enhancement, tend to be underestimated when evaluated by Tl-index calculation. Tl SPECT is not a reliable method for non-invasive tumour staging among the group of highly malignant astrocytomas. - Quantification of cerebral TI-uptake, defining the volume of viable tumour tissue, is a new method for astrocytoma chemotherapy monitoring. Results suggest that the method provides prognostic information, and information of treatment efficacy, at an earlier stage than CT. - We did not find a higher accuracy of quantitative Tl SPECT than of MR for monitoring purposes and our results indicated that treatment induced MR changes were interrelated with TI-uptake variations. - Multi-voxel H-MRS was difficult to apply for astrocytoma treatment monitoring, due to the anatomical

    To discuss the anatomic features, clinical presentations, diagnosis, differentiations and treatments of congenital fourth branchial anomaly(CFBA). The clinical data of 8 patients with CFBA were retrospectively analyzed. Of the 8 patients aging from 27 to 300 months (median age: 114 months), 4 male and 4 female; 3 untreated previously and 5 recurrent. All lesions, including 1 cyst, 3 sinus (with internal opening) and 4 fistula, located in the left necks. Three patients presented acute suppurative thyroiditis, 4 deep neck abscesses, and 1 neck lump. Preoperative examinations included barium esophagogram, direct laryngoscopy, ultrasonography, CT, MRI, and so on. The principles of managements were adequate drainage, infection control during acute period and radical surgery during quiescent period. Classic surgical approach consisted of complete excision of branchial lesions, dissection of recurrent laryngeal nerve and partial thyroidectomy. Selective neck dissection was applied in recurrent cases to extirpate branchial lesions, scarrings and inflammatory granuloma. Postoperatively, 1 case was with local incision infection which healed by wound care; 1 case was with temporary vocal cord paralysis which completely recovered 1 month after operation. No recurrence was found in all of 8 cases with follow-up of 13 to 42 months (median: 21 months). CFBA relates closely anatomically with recurrent laryngeal nerve and thyroid grand. The barium esophagogram and direct laryngoscopy are the most useful diagnostic tools. CT and MRI are all beneficial to the diagnosis of CFBA. The treatment key to CFBA is the complete excision of lesion during a quiescent period after inflammatory control, together with the dissection of recurrent laryngeal nerve, partial thyroidectomy and partial resection of lamina of thyroid cartilage (if necessary), which all can decrease the risk of complications and recurrence. For recurrent cases, selective neck dissection is a safe and effective surgical

    Seizure onset zone (SOZ) is currently defined by ictal epileptiform discharges, which are most commonly recorded as regional low-voltage fast waves or repetitive spikes. Interictal epileptiform discharges, on the other hand, are not specific enough for SOZ as they are recorded at zones other than the SOZ; they are also recorded from areas that do not generate the ictal pattern and from areas to which ictal discharges propagate. Besides spikes and sharp waves, a novel index of human epileptogenicity has been investigated in association with wide-band electroencephalography (EEG) analysis. We primarily noted the following during clinical neurophysiological analysis for clinical epilepsy. Recent development of digital EEG technology enabled us to record wide-band EEG in a clinical setting. Thus, high frequency (>200 Hz) and low frequency (<1 Hz) components can be reliably recorded using subdural electrodes. Direct current shift, slow shift, ripple, and fast ripple can be well delineated, and they will be potentially useful in the diagnosis and management of epileptic patients. Fiber tractography (morphological parameter) and cortico-cortical-evoked potentials with single cortical stimulation (electrophysiological parameter) elucidated cortico-cortical connections in human brain. The data thus obtained can help us understand the mechanism of seizure propagation and normal cortical functional connectivity. Non-invasive simultaneous recording of EEG and functional magnetic resonance imaging (fMRI) provided information on the roles of deep brain structures associated with scalp-recorded epileptiform discharges. Interventional neurophysiology can shed light on the non-pharmacological treatment of epilepsy. In this report, we discuss these novel electrophysiological approaches to the diagnosis and treatment of clinical epilepsy. (author)

    It is a challenging task to review transcranial magnetic stimulation (TMS) studies in neuropsychiatric disorders alongside assessments of longstanding clinical applications of ECT as an empirical treatment. The task is challenging because TMS was developed as a probe of neural mechanisms, whereas, in marked contrast, ECT has been a clinical technique from its inception. Since the onset of modern psychopharmacology, the understanding of the potential applications of ECT to neuropsychiatric disorders is generally restricted to case reports of patients with intractable disease that have had at least a partial response to ECT. Studies of the possible efficacy of TMS in neuropsychiatric conditions have a significant advantage over ECT as the treatments are associated with less morbidity. The only serious known complication in TMS is a risk of seizures that may increase in patients with neuropsychiatric conditions such as course brain disease. Only cortical structures are themselves accessible to TMS using current technology. Present TMS techniques, however, seem capable of affecting activity in deeper brain structures that are functionally linked to cortical brain regions. TMS permits novel explorations of relationships between regional brain activity and symptoms of a number of neuropsychiatric disorders, as well as in research relating activity in functionally related brain regions to modulation of cognition and affective states in healthy individuals. This is particularly true at present because TMS and powerful neuroimaging and neuropsychological tools are all making rapid advances simultaneously.

    This European guideline for the diagnosis and treatment of insomnia was developed by a task force of the European Sleep Research Society, with the aim of providing clinical recommendations for the management of adult patients with insomnia. The guideline is based on a systematic review of relevant meta-analyses published till June 2016. The target audience for this guideline includes all clinicians involved in the management of insomnia, and the target patient population includes adults with chronic insomnia disorder. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) system was used to grade the evidence and guide recommendations. The diagnostic procedure for insomnia, and its co-morbidities, should include a clinical interview consisting of a sleep history (sleep habits, sleep environment, work schedules, circadian factors), the use of sleep questionnaires and sleep diaries, questions about somatic and mental health, a physical examination and additional measures if indicated (i.e. blood tests, electrocardiogram, electroencephalogram; strong recommendation, moderate- to high-quality evidence). Polysomnography can be used to evaluate other sleep disorders if suspected (i.e. periodic limb movement disorder, sleep-related breathing disorders), in treatment-resistant insomnia, for professional at-risk populations and when substantial sleep state misperception is suspected (strong recommendation, high-quality evidence). Cognitive behavioural therapy for insomnia is recommended as the first-line treatment for chronic insomnia in adults of any age (strong recommendation, high-quality evidence). A pharmacological intervention can be offered if cognitive behavioural therapy for insomnia is not sufficiently effective or not available. Benzodiazepines, benzodiazepine receptor agonists and some antidepressants are effective in the short-term treatment of insomnia (≤4 weeks; weak recommendation, moderate-quality evidence).

    Nonspecific symptoms are common in all areas of medicine. Patients and caregivers can be frustrated when an illness cannot be reduced to a discrete pathophysiological process that corresponds with the symptoms. We therefore asked the following questions: 1) Which demographic factors and psychological comorbidities are associated with change from an initial diagnosis of nonspecific arm pain to eventual identification of discrete pathophysiology that corresponds with symptoms? 2) What is the percentage of patients eventually diagnosed with discrete pathophysiology, what are those pathologies, and do they account for the symptoms? We evaluated 634 patients with an isolated diagnosis of nonspecific upper extremity pain to see if discrete pathophysiology was diagnosed on subsequent visits to the same hand surgeon, a different hand surgeon, or any physician within our health system for the same pain. There were too few patients with discrete pathophysiology at follow-up to address the primary study question. Definite discrete pathophysiology that corresponded with the symptoms was identified in subsequent evaluations by the index surgeon in one patient (0.16% of all patients) and cured with surgery (nodular fasciitis). Subsequent doctors identified possible discrete pathophysiology in one patient and speculative pathophysiology in four patients and the index surgeon identified possible discrete pathophysiology in four patients, but the five discrete diagnoses accounted for only a fraction of the symptoms. Nonspecific diagnoses are not harmful. Prospective randomized research is merited to determine if nonspecific, descriptive diagnoses are better for patients than specific diagnoses that imply pathophysiology in the absence of discrete verifiable pathophysiology.

    Diagnosis during the initial stages of first-episode psychosis is particularly challenging but crucial in deciding on treatment. This is compounded by important differences in the two major classification systems, International Classification of Diseases, 10th revision (ICD-10) and Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). We aimed to compare the concordance between an operationalized diagnosis using Operational Criteria Checklist (OPCRIT) and treating clinician-generated diagnosis in first episode psychosis diagnosis and its correlation with treatment prescribed.

    While non-invasive ventilation aimed at avoiding intubation has become the modality of choice to treat mild to moderate acute respiratory acidosis, many severely acidotic patients (pH respiratory acidosis was only feasible when blood flow rates of 750 to 1000 mL/minute (19Fr catheter) were used. Maximal CO2-elimination was 146.1 ± 22.6 mL/minute, while pH increased from 7.13 ± 0.08 to 7.41 ± 0.07 (blood flow of 1000 mL/minute; sweep gas flow 16 L/minute). Accordingly, a sweep gas flow of 8 L/minute resulted in a maximal CO2-elimination rate of 138.0 ± 16.9 mL/minute. The 14.5Fr catheter allowed a maximum CO2 elimination rate of 77.9 mL/minute, which did not result in the normalization of pH. Veno-venous ECCO2R may serve as a treatment option for severe respiratory acidosis. In this porcine model, ECCO2R was most effective when using blood flow rates ranging between 750 and 1000 mL/minute, while an increase in sweep gas flow from 8 to 16 L/minute had less impact on ECCO2R in this setting.

    Oral cancer is an important health issue. The WHO predicts a continuing worldwide increase in the number of patients with oral cancer, extending this trend well into the next several decades. In the US the projected number of new cases of oral and oropharyngeal cancer will exceed 31,000 per year. Mortality due to cancers in this region exceeds the annual death rate is the US caused by either cutaneous melanoma or cervical cancer. Significant agents involved in the etiology of oral cancer in Western countries include sunlight exposure, smoking and alcohol consumption. Use of the areca or betel nut in many cultures is a major etiological factor outside of the USA. Other etiologic factors associated with oral squamous cell carcinoma, but far less significant statistically, include syphilis and sideropenic dysphagia. Recently, strong evidence for an etiological relationship between human papilloma virus and a subset of head and neck cancers has been noted. It is generally accepted that most sporadic tumors are the result of a multi-step process of accumulated genetic alterations. These alterations affect epithelial cell behavior by way of loss of chromosomal heterozygosity which in turn leads to a series of events progressing to the ultimate stage of invasive squamous cell carcinoma. The corresponding genetic alterations are reflected in clinical and microscopic pathology from hyperplasia through invasiveness. A wide range of mucosal alternations fall within the rubric of leukoplakia. Proliferative verrucous leukoplakia represents a relatively new type of leukoplakia that is separate from the more common or less innocuous form of this condition. Erythroplakia is particularly relevant considering its almost certain relationship with dysplasia or invasive carcinoma. Squamous cell carcinoma will develop from antecedent dysplastic oral mucosal lesions if an early diagnosis has not been made and treatment given. Early diagnosis within stages I and II correspond to a vastly

    Lactose malabsorption is a common condition caused by reduced expression or activity of lactase in the small intestine. In such patients, lactose intolerance is characterized by abdominal symptoms (e.g. nausea, bloating, and pain) after ingestion of dairy products. The genetic basis of lactose malabsorption is established and several tests for this condition are available, including genetic, endoscopic, and H2-breath tests. In contrast, lactose intolerance is less well understood. Recent studies show that the risk of symptoms after lactose ingestion depends on the dose of lactose, lactase expression, intestinal flora, and sensitivity of the gastrointestinal tract. Lactose intolerance has recently been defined as symptoms developing after ingestion of lactose which do not develop after placebo challenge in a person with lactose maldigestion. Such blinded testing might be especially important in those with functional gastrointestinal diseases in whom self-reported lactose intolerance is common. However, placebo-controlled testing is not part of current clinical practice. Updated protocols and high-quality outcome studies are needed. Treatment options of lactose intolerance include lactose-reduced diet and enzyme replacement. Documenting the response to multiple doses can guide rational dietary management; however, the clinical utility of this strategy has not been tested. This review summarizes the genetic basis, diagnosis, and treatment of lactose malabsorption and intolerance.

    Full Text Available Pervasive developmental disorders are now commonly referred to as autism spectrum disorders (ASDs. ASDs present with a range of severity and impairments, and often are a cause of severe disability, representing a major public health concern. The diagnostic criteria require delays or abnormal functioning in social interaction, language, and/or imaginative play within the first 3 years of life, resulting in a deviation from the developmental pattern expected for the age. Because establishing a diagnosis of ASD is possible as early as 18-24 months of age, clinicians should strive to identify and begin intervention in children with ASD as soon as signs are manifest. Increasing efforts are underway to make ASD screening universal in pediatric healthcare. Given the crucial importance of early identification and multiple modalities of treatment for ASD, this review will summarize the diagnostic criteria, key areas for assessment by clinicians, specific scales and instruments for assessment, and discussion of evidence-based treatment programs and the role of specific drug therapies for symptom management.

    Radioisotopes play a significant and indispensable role in studying and understanding biological processes, viewing internal biological structures and processes for diagnosis of abnormal conditions, and in cure and alleviation of sufferings of cancer patients. With the availability of large number of diagnostic agents, SPECT and PET are matured technologies and is the mainstay of functional diagnostic imaging. Treatment of cancer with radioisotopes provides effective cure and the palliation of intractable symptoms. In a country like India, where more than 70% patients present in advanced and inoperable stages, radiation therapy plays an important role. While PET has seen the maximum growth in the last 15 years, next phase of growth of nuclear medicine is expected to be in radionuclide therapy. The new imaging modalities that appeared on the market at this very beginning of the new century and the new molecules and therapeutic technologies associated to the radioactivity open a very encouraging window that fascinates experts from other medical disciplines, and more particularly the oncologists, the hematologists and the neurologists. Cancer treatment remains at the forefront of any new therapeutic modality

    Basal encephalocele is a rare disease that predominantly occurs in children. Its most common symptoms include nasal liquorrhea, difficulty in nasal breathing, and deformity of the naso-orbital region. The study group included 19 patients with basal encephalocele, aged 2 months to 18 years. Ten (59%) patients were operated on through a transnasal endoscopic approach; 3 (17.5%) patients were operated on through a transcranial approach; 4 (23.5%) patients were operated on using a combined approach: the patients underwent simultaneous elimination of a cranio-orbital region deformity using the basal transcranial approach as well as hernial sac resection and hernioplasty using the transnasal endoscopic approach. Two children had no surgery due to minimal symptoms and a lack of cerebrospinal fluid leak. Application of the algorithms for diagnosis and treatment of encephalocele, suggested by the authors, enabled making the timely diagnose, defining the optimal surgical tactics, and achieving good treatment results. A differentiated approach to the choice of a surgical technique for basal encephalocele, the use of auto-tissues for skull base reconstruction, intraoperative and postoperative lumbar drainage, and simultaneous elimination of deformity of the fronto-naso-orbital region enable avoiding complications and achieving good functional and aesthetic results.

    Hyponatraemia, defined as a serum sodium concentration <135 mmol/l, is the most common disorder of body fluid and electrolyte balance encountered in clinical practice. It can lead to a wide spectrum of clinical symptoms, from subtle to severe or even life threatening, and is associated with increased mortality, morbidity and length of hospital stay in patients presenting with a range of conditions. Despite this, the management of patients remains problematic. The prevalence of hyponatraemia in widely different conditions and the fact that hyponatraemia is managed by clinicians with a broad variety of backgrounds have fostered diverse institution- and speciality-based approaches to diagnosis and treatment. To obtain a common and holistic view, the European Society of Intensive Care Medicine (ESICM), the European Society of Endocrinology (ESE) and the European Renal Association - European Dialysis and Transplant Association (ERA-EDTA), represented by European Renal Best Practice (ERBP), have developed the Clinical Practice Guideline on the diagnostic approach and treatment of hyponatraemia as a joint venture of three societies representing specialists with a natural interest in hyponatraemia. In addition to a rigorous approach to methodology and evaluation, we were keen to ensure that the document focused on patient-important outcomes and included utility for clinicians involved in everyday practice.

    Bladder cancer is the sixth most common cancer in the Western world. Patients with bladder cancer require close monitoring, which may include frequent cystoscopy and urine cytology. Such monitoring results in significant health care cost. The application of epigenetics may allow for a risk adapted approach and more cost-effective method of monitoring. A number of epigenetic changes have been described for many cancer sites, including the urinary bladder. In this review, we discuss the use of epigenetics in bladder cancer and the potential diagnostic and therapeutic applications. A comprehensive search of the English medical literature was conducted in PubMed using the terms microRNA regulation, DNA methylation, histone modification and bladder cancer. The most important epigenetic changes include DNA methylation, histone modification and microRNA regulation. Both DNA hypomethylation and hypermethylation have been associated with higher rate of cancer. The association of epigenetic changes with bladder cancer has led to the research of its diagnostic and prognostic implications as well as to the development of novel drugs to target these changes with the aim of achieving a survival benefit. Recently, epigenetics has been shown to play a much greater role than previously anticipated in the initiation and propagation of many tumors. The use of epigenetics for the diagnosis and treatment of bladder cancer is an evolving and promising field. The possibility of reversing epigenetic changes may facilitate additional cancer treatment options in the future.

    Full Text Available Laura D Garrett Department of Veterinary Clinical Medicine, University of Illinois College of Veterinary Medicine, Urbana, IL, USA Abstract: Mast cell tumors (MCTs are the most common malignant skin cancer in dogs, and significant variability exists in their biological behavior. Most MCTs are cured with appropriate local therapy, but a subset shows malignant behavior with the potential to spread to lymph nodes, liver, spleen, and other areas and to thus become a systemic cancer. Because of this variable behavior, it is difficult to predict how any individual tumor is going to behave. The variability thus creates uncertainty in deciding what a particular dog's prognosis is, whether staging tests to assess for metastasis are needed, and even what treatments will be necessary for best outcome. In addition to controversies over the potential for development of systemic disease, or diffuse metastasis, controversies also exist over what treatment is needed to best attain local control of these tumors. This article will briefly discuss the diagnosis of MCTs in dogs and will summarize the literature in regards to the controversial topics surrounding the more aggressive form of this disease, with recommendations made based on published studies. Keywords: mitotic index, mastocytosis, tyrosine kinase inhibitor, histologic grade

    The AV-reentrant tachycardia (AVRT) is a supraventricular tachycardia with an incidence of 1-3/1000. The pathophysiological basis is an accessory atrioventricular pathway (AP). Patients with AVRT typically present with palpitations, an on-off characteristic, anxiety, dyspnea, and polyuria. This type of tachycardia may often be terminated by vagal maneuvers. Although the clinical presentation of AVRT is quite similar to AV-nodal reentrant tachycardias, the correct diagnosis is often facilitated by analyzing a standard 12-lead ECG at normal heart rate showing ventricular preexcitation. Curative catheter ablation of the AP represents the therapy of choice in symptomatic patients. This article is the fourth part of a series written to improve the professional education of young electrophysiologists. It explains pathophysiology, symptoms, and electrophysiological findings of an invasive EP study. It focusses on mapping and ablation of accessory pathways.

    The objective of this study was to evaluate the method of prenatally estimating an appropriate clinical outcome in fetal hydrocephalus. Retrospective study, single institute (Osaka National Hospital). Hundred and seventeen cases with fetal hydrocephalus treated at Osaka National Hospital from 1992 to 2010 were analysed. Of the 117 cases analysed, 38% are diagnosed as isolated ventriculomegaly (IVM), 51% as other types of malformation (30 cases of myelomeningocele, 4 cases of holoprosencephaly, 4 of Dandy Walker syndrome, 10 of arachnoid cyst and 6 of encephalocele etc.) and 11% as secondary hydrocephalus. They are diagnosed between 17 and 40 weeks of gestation (average 27 weeks), 17% diagnosed between 17 and 21 weeks, 30% between 22 and 27 weeks and 53% after 28 weeks. With the exception of 9 aborted cases and 30 unknown cases too young to be evaluated or lost due to lack of follow-up, final outcome was analyzed in 78 cases. Of these 78 cases, 15% died in utero or after birth, 23% showed severe retardation, 17% moderate retardation, 26% mild retardation, and 19% showed good outcome. Long term consequences were mostly influenced by basic disease and accompanied anomalies. Hydrocephalus associated with arachnoid cyst, atresia of Monro, corpus callosum agenesis and hydrocephalus due to fetal intracranial hemorrhage are categorized in the good outcome group. On the other hand, holoprosencephaly, hydrocephalus associated with encephalocele, syndromic hydrocephalus and hydrocephalus due to fetal virus infection are categorized in the poor outcome group. In order to accurate diagnosis and proper counseling, establishment of diagnosis protocol and treatment policy for fetal hydrocephalus including not only fetal sonography, fetal MRI, toxoplasma, rubella, cytomegalovirus, herpes simplex (TORCH) screening test but also chromosomal and gene testing is required.

    To analyze gray-scale US, color and duplex Doppler US, and angiographic findings in patients with acquired uterine arteriovenous malformations (AVMs), and to evaluate the usefulness of these modalities in the diagnosis of this disease and the effect of transcatheter arterial embolization in its treatment. During a recent seven-year period, we diagnosed 21 cases of acquired uterine AVM. Nineteen of these patients had a history of causative D and C (between one and seven D and C procedures per patient), one had a history of causative cesarean section, and one had cervical conization. All patients underwent transabdominal and endovaginal gray-scale, color Doppler, and duplex Doppler US and angiography, with therapeutic embolization of bilateral uterine arteries. The majority underwent follow-up Doppler US after embolization. The gray-scale US morphology of uterine AVMs included subtle myometrial inhomogeneity and multiple distinct, small anechoic spaces in the thickened myometrium or endometrium. Color Doppler US showed a tangle of tortuous vessels with multidirectional, high-velocity arterial flow, which was focally or asymmetrically distributed. Duplex Doppler US depicted a waveform of fast arterial flow with low resistance, while angiography demonstrated a complex tangle of vessels supplied by enlarged uterine arteries, in association with early venous drainage during the arterial phase, and staiss of contrast medium within abnormal vasculature. Where AVMs were combined with a pseudoaneurysm, this finding was observed. Transcatheter arterial embolization provided a complete cure, without recurrence. Color and duplex Doppler US in an appropriate modality for the detection and diagnosis of uterine AVMs and for follow-up after embolization. Transcatheter arterial embolization is a safe and effective method of treating this disease

    Exercise and sports activity are beneficial both physically and psychologically but excessive exercise may have adverse physiological and psychological effects. There are methodological issues in the definition, diagnosis and etiology of exercise addiction. Several questionnaires and diagnostic tools have been developed and validated and they show high validity and reliability. Exercise addiction has been suggested as having an obsessive-compulsive dimension as well as rewarding aspects that may include it among the behavioral addictions. Biological studies show that in rodents, exercise such as wheel running activates the dopamine reward system and thus contributing to stress reduction. Further evidence suggests that running is associated with endorphins and cannabinoids thus explaining the "runners high" or euphoric feelings that may lead to exercise addiction. Genetic studies suggest that genes which control preference for drugs also control the preference for naturally rewarding behaviors such as exercise. Psychological studies also explain exercise addiction in terms of reward, habituation, social support, stress-relief, avoidance of withdrawal and reduction of anxiety. It has been suggested that exercise addiction is a part of a continuum of sportive activity that develops in stages from the recreational exercise to at-risk exercise, problematic exercise and finally into exercise addiction. Assessment and treatment should take into account the various stages of exercise addiction development, its comorbidity with other psychiatric disorders such as eating disorders or substance use and alcohol disorders. Treatment approaches for exercise addiction are based on the cognitive-behavioral approach but little is known about their effectiveness. A single-case study shows promise of pharmacological treatment for exercise addiction and further studies are required. This review summarizes diagnostic and phenomenology of exercise addiction with emphasis on

    Various drugs and surgical procedures have been utilized for the treatment of trigeminal neuralgia (TN). Despite numerous available approaches, the results are not completely satisfying. The need for more contemporaneous drugs to control the pain attacks is a common experience. Moreover, a number of patients become drug resistant, needing a surgical procedure to treat the neuralgia. Nonetheless, pain recurrence after one or more surgical operations is also frequently seen. These facts reflect the lack of the precise understanding of the TN pathogenesis. Classically, it has been related to a neurovascular compression at the trigeminal nerve root entry-zone in the prepontine cistern. However, it has been evidenced that in the pain onset and recurrence, various neurophysiological mechanisms other than the neurovascular conflict are involved. Recently, the introduction of new magnetic resonance techniques, such as voxel-based morphometry, diffusion tensor imaging, three-dimensional time-of-flight magnetic resonance angiography, and fluid attenuated inversion recovery sequences, has provided new insight about the TN pathogenesis. Some of these new sequences have also been used to better preoperatively evidence the neurovascular conflict in the surgical planning of microvascular decompression. Moreover, the endoscopy (during microvascular decompression) and the intraoperative computed tomography with integrated neuronavigation (during percutaneous procedures) have been recently introduced in the challenging cases. In the last few years, efforts have been made in order to better define the optimal target when performing the gamma knife radiosurgery. Moreover, some authors have also evidenced that neurostimulation might represent an opportunity in TN refractory to other surgical treatments. The aim of this work was to review the recent literature about the pathogenesis, diagnosis, and medical and surgical treatments, and discuss the significant advances in all these fields

    Aspirin-sensitive rhinosinusitis is a non-allergic, non-infectious perennial eosinophilic rhinitis starting in middle age and rarely seen in children. It may also been seen in atopic patients who have developed a mixed type rhinitis with recurrent airway infections. There is an intolerance to aspirin and most other NSAID. An intolerance to tartrazine, food additives, alcohol, narcotics and local anaesthetics can follow. Most aspirin-sensitive patients develop nasal polyps. Untreated, it can lead to asthma. The frequency of aspirin intolerance is 6.18% in patients with perennial rhinitis and 14.68% in patients with nasal polyps. Immunologic studies of the blood and the nasal polyps show a hyperreactive immune system with an activation of the eosinophil granulocytes due to a TH1-lymphocyte-activation. In atopic subjects with a mixed type rhinitis, we found a TH2- and B-lymphocyte-activation as well. Inhibition of eosinophil apoptosis might be a second remarkable change in the immune system of aspirin-sensitive patients. A key pathogenic event for aspirin sensitivity is the change of the leukotriene pathway for arachidonic acid metabolism releasing high amounts of leukotrienes LTC4, LTD4 and LTE4, effective chemoattractants and activators of inflammatory cells. For the diagnosis of aspirin intolerance, nasal, bronchial and oral challenge are available. The sensitivity of nasal challenge with lysine-aspirin for the diagnosis of aspirin-sensitive rhinitis is 0.93, the specificity 0.97. It is the safest test in aspirin-sensitive asthmatics causing bronchial side effects only in 0.45%. Therapy of aspirin-sensitive rhinosinusitis includes avoidance of aspirin and NSAID. A general down regulation of the immune response with glucocorticosteroids is an effective means. We prefer a maintenance dose of budesonid 400 micrograms a day. Systemic steroids for a reversibility test or in exacerbation due to viral infection are given in a dose of 50 mg a day for one week. If steroids

    Internet gaming disorder (IGD) is a new disorder currently positioned in the appendix of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Few clinical studies report that psychological and pharmacological interventions can significantly reduce the severity of IGD symptomatology. The aim of this review was to assess current knowledge of the short- and long-term benefits of IGD interventions. This review presents a systematic evaluation of definitions of diagnosis and treatment outcomes employed in IGD treatment studies, including an assessment of goodness of fit with the DSM-5 classification. A computer database search of Academic Search Premier, PubMed, PsychINFO, ScienceDirect, Web of Science, and Google Scholar was conducted to identify all available research evidence on Internet gaming disorder treatment (N = 8 studies). Diagnostic and treatment outcome parameters were systematically evaluated. Several weaknesses of IGD treatment literature were identified. Only 2 treatment studies have employed an equivalent method of diagnosis for IGD. Studies have not assessed formative change in diagnostic status at posttreatment or follow-up. Duration of follow-up has been inadequate to assess relapse and remission. Posttreatment assessment has been predominantly limited to IGD symptomatology, comorbidity, and frequency of gaming behavior. Currently, there is insufficient evidence to warrant suggestion that trialled IGD interventions confer a long-term therapeutic benefit. Several improvements to study design and reporting are proposed to guide future studies of IGD. © 2014 Wiley Periodicals, Inc.

    Cystic fibrosis (CF) is an autosomal recessive genetic disorder characterized by dysfunction of the CFTR gene. It is a multisystem disease that most often affects White individuals. In recent decades, various advances in the diagnosis and treatment of CF have drastically changed the scenario, resulting in a significant increase in survival and quality of life. In Brazil, the current neonatal screening program for CF has broad coverage, and most of the Brazilian states have referral centers for the follow-up of individuals with the disease. Previously, CF was limited to the pediatric age group. However, an increase in the number of adult CF patients has been observed, because of the greater number of individuals being diagnosed with atypical forms (with milder phenotypic expression) and because of the increase in life expectancy provided by the new treatments. However, there is still great heterogeneity among the different regions of Brazil in terms of the access of CF patients to diagnostic and therapeutic methods. The objective of these guidelines was to aggregate the main scientific evidence to guide the management of these patients. A group of 18 CF specialists devised 82 relevant clinical questions, divided into five categories: characteristics of a referral center; diagnosis; treatment of respiratory disease; gastrointestinal and nutritional treatment; and other aspects. Various professionals working in the area of CF in Brazil were invited to answer the questions devised by the coordinators. We used the PubMed database to search the available literature based on keywords, in order to find the best answers to these questions. RESUMO A fibrose cística (FC) é uma doença genética autossômica recessiva caracterizada pela disfunção do gene CFTR.

    Full Text Available The small intestinal neoplasia group includes different types of lesions and are a relatively rare event, accounting for only 3-6% of all gastrointestinal (GI neoplasms and 1-3% of all GI malignancies. These lesions can be classified as epithelial and mesenchymal, either benign or malignant. Mesenchymal tumours include stromal tumours (GIST and other neoplasms that might arise from soft tissue throughout the rest of the body (lipomas, leiomyomas and leiomyosarcomas, fibromas, desmoid tumours, and schwannomas. Other lesions occurring in the small bowel are carcinoids, lymphomas, and melanomas. To date, carcinoids and GIST are reported as the most frequent malignant lesions occurring in the small bowel. Factors that predispose to the development of malignant lesions are different, and they may be hereditary (Peutz-Jeghers syndrome, familial adenomatous polyposis, hereditary non-polyposis colorectal cancer, neuroendocrine neoplasia Type 1, von Hippel-Lindau disease, and neurofibromatosis Type 1, acquired (sporadic colorectal cancer and small intestine adenomas, coeliac disease, Crohn’s disease, or environmental (diet, tobacco, and obesity. Small bowel tumours present with different and sometimes nonspecific symptoms, and a prompt diagnosis is not always so easily performed. Diagnostic tools, that may be both radiological and endoscopic, possess specificity and sensitivity, as well as different roles depending on the type of lesion. Treatment of these lesions may be different and, in recent years, new therapies have enabled an improvement in life expectancy.

    Calcium-based (CaXs) biomaterials including calcium phosphates, calcium carbonates, calcium silicate and calcium fluoride have been widely utilized in the biomedical field owing to their excellent biocompatibility and biodegradability. In recent years, CaXs biomaterials have been strategically integrated with imaging contrast agents and therapeutic agents for various molecular imaging modalities including fluorescence imaging, magnetic resonance imaging, ultrasound imaging or multimodal imaging, as well as for various therapeutic approaches including chemotherapy, gene therapy, hyperthermia therapy, photodynamic therapy, radiation therapy, or combination therapy, even imaging-guided therapy. Compared with other inorganic biomaterials such as silica-, carbon-, and gold-based biomaterials, CaXs biomaterials can dissolve into nontoxic ions and participate in the normal metabolism of organisms. Thus, they offer safer clinical solutions for disease theranostics. This review focuses on the state-of-the-art progress in CaXs biomaterials, which covers from their categories, characteristics and preparation methods to their bioapplications including diagnosis, treatment, and theranostics. Moreover, the current trends and key problems as well as the future prospects and challenges of CaXs biomaterials are also discussed at the end.

    Full Text Available Abstract: Introduction: Leptospirosis is an acute febrile disease caused by the leptospira. It is considered a zoonosis that affects a variety of animals, both wild and domestic (mainly rodents. Humans become infected accidentally by contact with urine or tissues from infected animals. This pathology has variable clinical manifestations, ranging from inapparent infections and aseptic meningitis, to severe forms such as the Weil syndrome. Development: We present the case of a young patient of 22 years old with fever quantified peaks of 40° C, chills, profuse sweating, headache, muscle and joint pain in knees and malleoli, retroorbital and retrosternal pain; and appetite loss. The symptoms occurred after 20 days of having practiced extreme water sports. Conclusion: The late diagnosis of the patient and hospital readmission are the result of several factors; First, the homology with other infectious diseases that present acute febrile illness with similar symptoms as dengue , malaria, influenza , yellow fever , brucellosis; and secondly the lack of expertise and poor contact with patients who present this disease by the medical staff. Correct antibiotic treatment and proper support reduce morbidity and mortality. The objective of this article is to describe a case of human leptospirosis and make a review of the literature in order to analyze the epidemiological characteristics and relevant clinical manifestations.

    Orthodontists are fully prepared to treat the problems of occlusion that they are called upon to deal with every day. On the other hand temporo-mandibular joint disorders present more obscure difficulties from the point of view of detection and diagnosis as well the management of their treatment. That is why a profound understanding of the anatomical and physiological functioning of the temporo-mandibular joint has become indispensable for today's orthodontists who are now asked to detect and diagnose an assortment of TMJ disturbances whose etiology may vary greatly. By performing a rigorous diagnostic procedure, based on a thorough clinical examination supported by careful axiographic and radiological studies, of temporo-mandibular malfunctioning and its underlying etiological causes, which are primarily dento-alveolar and occlusal in nature, orthodontists will be able to adopt an appropriate therapeutic approach that might be purely orthodontic or multi-disciplinary and carried out with the collaboration of specialists in occlusion, oral surgery, and even osteopathy.

    Full Text Available Rotator cuff (RTC disease is a particularly prevalent cause of shoulder pain and weakness presenting to primary care physicians, internists, rheumatologists, and orthopedists. An understanding of the anatomy of the RTC tendons and the underlying pathogenesis aids in the diagnosis, which is based largely on history and specific physical examination tests. Imaging may further define the pathology and aid in the evaluation of other sources of shoulder pain. Injuries to the RTC range from tendonitis to partial thickness tears to full thickness tears. The majority of patients with impingement and some cases of partial thickness tears may be managed effectively with non-operative measures including non-steroidal anti-inflammatory drugs, local injections, and physical therapy. Predictors of a good outcome with non-operative treatment include pre-injury strength, ability to raise the arm to the level of the shoulder, and a more acute presentation. Persistent symptoms may require operative intervention including debridement, subacromial decompression, and/or RTC repair. Acute full thickness tears in younger patients in addition to failed non-operative management of full thickness tears in older patients are the most likely to require surgery, which may be done open or arthroscopically. The majority of tears are amenable to the less invasive arthroscopic method, which yields good success rates and high patient satisfaction.

    ROHIT PANDEY

    Full Text Available ABSTRACT Langerhans cell histiocytosis (LCH is characterised by an abnormal histiocytic accumulation in tissues such as the lung, spleen, bone marrow, skin, central nervous system, liver and lymph nodes, causing focal or systemic effects. No specific clinical & radiographic presentation of LCH is described in literature. This poses a diagnostic dilemma for surgeons. The scapula is the site of 3% of bone tumours, while for LCH it is the least common site. In a 10-year-old boy with isolated lesion of the scapula with no other systemic involvement, and no specific finding in MRI or CT scan of scapula, diagnosis was confirmed on biopsy. Division into single and multi-system disease is paramount in treatment, given that it is a single system disease. The patient improved clinically on follow-up of 2 years. The scapula is one of the rarest site of LCH, and because various lesions mimic each other, a biopsy is always required, with immunohistochemistry for CD68 & S-100. This was only a single system disease, so conservative management was performed, and the patent improved clinically.

    Full Text Available Chronic urticaria is defined as a skin disease with central induration (wheal and erythema formation around it (flare that appears at least twice a week and remains at least for 6 weeks continually. The incidence of urticaria in children is about 0.1-3%. Most cases of chronic urticaria occur in children between 6-11 years. Autoimmune and allergy immaturity is one of the reasons of lower incidence of chronic urticaria in younger children. Quality of life impairment in children with urticaria has been known to be similar to diseases with severe atopic dermatitis, epilepsy, diabetes mellitus and asthma. There are several causes for chronic urticaria in children in different reports. In most of cases the known etiologic agents are varies from 21 to 83%. Overall, infectious causes of chronic urticaria in children are more common and obvious than other in adults .In most cases, the cause of chronic urticaria are idiopathic or autoimmune. Urticaria severity divided to mild, moderate and severe was based on the number of wheals and severity of pruritus. Diagnosis of chronic urticaria is based on a good history and physical examination. The treatment of chronic urticaria is a patient education that is to remove the triggering and aggravating agents, resolving and treating of the known disease and the use of various medicines based on the history and clinical findings. The first medical therapeutics lines in children are anti-histamines, beta-blocker H1 and new generation of non-sedating agents.

    2008-01-01

    Background: Rhabdomyolysis is a common disorder resulting from a large variety of causes. We describe the MRI features and their importance for diagnosis and treatment. Patients and methods: Between 2003 and 2006, four male patients (age range: 25-33 years) with rhabdomyolysis were studied via 1.5 T MRI (GE, Siemens). In all the patients, T1- and T2-weighted sequences with and without fat suppression, short tau inversion recovery (STIR) and gradient-echo sequences were obtained in axial, coronal and sagittal planes. In one patient, contrast material was given. Results: Two patients presented rhabdomyolysis due to drug abuse, one due to intense exercise and the last one due to long unconsciousness with compression of the paravertebral musculature. Two patients had acute kidney failure. The affected muscles showed an increased signal intensity on T2-weighted and STIR sequences and decreased on T1-weighted sequences. In one patient, intramuscular hemorrhage was observed on T1-weighted and gradient-echo sequences. In the patient with kidney failure, a globular swelling of the kidney with alteration of the corticomedullary differentiation on T2-weighted sequences with fat saturation and hypointensity of the renal medulla on T1-weighted contrast enhanced images was found. Discussion: Immediate recognition of rhabdomyolysis is important to prevent late complications. MRI is the method of choice to evaluate the distribution and extension of the affected muscles, especially when fasciotomy is considered for treatment. Even though the MRI findings are non-specific, the sensitivity in the detection of muscle involvement is higher than CT or US

In one patient, intramuscular hemorrhage was observed on T1-weighted and gradient-echo sequences. In the patient with kidney failure, a globular swelling of the kidney with alteration of the corticomedullary differentiation on T2-weighted sequences with fat saturation and hypointensity of the renal medulla on T1-weighted contrast enhanced images was found. Discussion: Immediate recognition of rhabdomyolysis is important to prevent late complications. MRI is the method of choice to evaluate the distribution and extension of the affected muscles, especially when fasciotomy is considered for treatment. Even though the MRI findings are non-specific, the sensitivity in the detection of muscle involvement is higher than CT or US.

    To establish some guidelines for the definition, diagnosis, and treatment of failed posterior urethroplasty. We identified 20 successive patients who required a secondary endoscopic or surgical procedure after anastomotic repair of a postpelvic fracture urethral injury from 1979 to 2010. Of the 20 patients, 18 had undergone perineal repair and 2 a perineo-abdominal procedure. Their medical records were reviewed with a focus on 6 postoperative items: symptoms, onset of unsuccessful result, urethral calibration, urethrocystography, urethroscopy, and treatment. Follow-up ranged from 1 to 25 years (mean 14). Of the 20 patients, 11 (55%) presented shortly after removal of the urethral stent with failure to void (n = 9) or incontinence (n = 2), and 9 (45%) presented 1 month to 12 years after surgery with a weak stream. Early failures resulted from obstruction at the site of repair in 5 patients, retraction of the bulbar urethra in 3, wrong anastomosis to a false tract in 1, and an open bladder neck in 2. Correction was accomplished by salvage urethroplasty in 8 patients and bladder neck repair in 2. Late failures resulted from narrowing of the anastomosis and were corrected by direct visual internal urethrotomy in 7 patients and surgery in 2. Unsuccessful outcomes can be encountered shortly after removal of the urethral stent or delayed for several months or years after surgery. Early cases present by an inability to void or incontinence and usually require salvage urethroplasty or bladder neck repair. Late cases present by a weak urinary stream, are due to narrowing of the anastomosis, and are usually corrected by direct visual internal urethrotomy. Copyright © 2012 Elsevier Inc.

    Haemonchus contortus is a highly pathogenic, blood-feeding nematode of small ruminants, and a significant cause of mortalities worldwide. Haemonchosis is a particularly significant threat in tropical, subtropical and warm temperate regions, where warm and moist conditions favour the free-living stages, but periodic outbreaks occur more widely during periods of transient environmental favourability. The clinical diagnosis of haemonchosis is based mostly on the detection of anaemia in association with a characteristic epidemiological picture, and confirmed at postmortem by the finding of large numbers of H. contortus in the abomasum. The detection of impending haemonchosis relies chiefly on periodic monitoring for anaemia, including through the 'FAMACHA' conjunctival-colour index, or through faecal worm egg counts and other laboratory procedures. A range of anthelmintics for use against H. contortus is available, but in most endemic situations anthelmintic resistance significantly limits the available treatment options. Effective preventative programmes vary depending on environments and enterprise types, and according to the scale of the haemonchosis risk and the local epidemiology of infections, but should aim to prevent disease outbreaks while maintaining anthelmintic efficacy. Appropriate strategies include animal management programmes to avoid excessive H. contortus challenge, genetic and nutritional approaches to enhance resistance and resilience to infection, and the monitoring of H. contortus infection on an individual animal or flock basis. Specific strategies to manage anthelmintic resistance centre on the appropriate use of effective anthelmintics, and refugia-based treatment schedules. Alternative approaches, such as biological control, may also prove useful, and vaccination against H. contortus appears to have significant potential in control programmes.

    Purpose: To report the success of groin nodal lymphography in the diagnosis and treatment of genital lymphedema. Methods and Materials: We present one female (8 years old [patient no. 1]) and two male (69 and [patient no. 2] 31 years old [patient no. 3], respectively) patients with genital lymphedema in whom conservative treatment failed. The girl also had lymphorrhagia. Genital lymphedema was caused by radical cystectomy (patient no. 2), lymphatic hyperplasia (patient no. 1), and idiopathic lymphangitis (patient no. 3). All of them underwent ultrasound-guided bilateral groin lymph node puncture. Afterward, 4-8 ml Lipiodol Ultra-Fluide (Guerbet) were injected at a rate of 0.2 ml/s. Lipiodol progression was assessed by fluoroscopy. Computed tomography scan of the abdomen and pelvis was performed immediately after and again at 24 h after the procedure to confirm the leak. The follow-up period was 15, 13, and 9 months, respectively. Technical success was considered as bilateral pelvic and abdominal filling of lymphatic vessels. Therapeutic success was considered as improvement or disappearance of genital lymphedema and/or lymphorrhagia. Results: Lipiodol leak to the scrotum was observed in patients no. 2 and 3. Lymphaticopelvic fistula and genital lymphatic hyperplasia were seen in patient no. 1. Genital lymphedema diminished within 1 week and almost disappeared in two cases (patients no. 1 and 3) or significantly improved (patient no. 2). lymphorrhagia also resolved in patient no. 1. No recurrence or worsening was detected during follow-up. Conclusion: Therapeutic lymphangiography by lymph node injection seems to be effective to treat genital lymphedema. Lymph node puncture lymphangiography is feasible and less cumbersome than pedal lymphangiography.

    Four cases of lissencephaly were analyzed in light of clinical manifestations, CT findings and the state of hydrocephalus. Lissencephaly had been diagnosed mainly by autopsy until CT scan was introduced in the early 1970's. Since then, diagnosis of lissencephaly early in life is possible. Presently the major interest in this congenital CNS anomaly, which is caused by a neuronal migration disorder in the relatively late stages of fetal development, is to learn the dynamic pathophysiological state and management. The purpose of this paper is to analyze those points of lissencephaly in diagnosis during life and possible treatment in the hydrocephalic state. The common findings in CT in all four cases are as follows: No. 1. smooth cortical surface (agyria--pachygyria), No. 2. wide sylvian fissure (complete or incomplete lack of opercularization, No. 3. ventricular dilatation (remarkable bilateral enlargement of lateral ventricle and third ventricle--colpocephaly), No. 4. wide subdural or subarachnoid space in supratentorial region, No. 5. periventricular low density, No. 6. midline cavum, No. 7. normal CT findings in posterior fossa structure. Three out of four patients demonstrated full or bulged and tense anterior fontanella. Because of this suggestion of increased intracranial pressure and enlarged ventricles with periventricular lucency in CT findings, one patient underwent CT cisternography for dynamic analysis of the CSF circulation and continuous ICP monitoring for dynamic evaluation of the ICP pattern. The results revealed very much delayed CSF circulation and intermittently increased. ICP, with pressure waves appearing in 35.7 % of all recordings. (J.P.N.)

    Conduct disorders are the most frequent psychiatric diagnosis in the pediatric and adolescent population, with different etiology and difficult to treat. Delinquent, aggressive, and impulsive behavior, lack of empathy and inability to predict possible consequences of the behavior lead to significant desadaptation and danger for these patients. In clinical practice, focus is usually given on social and psychological causes of conduct disorders ignoring possible biological factors in etiology and pathophysiology. A clinical case described in this article shows the linkage between frontal brain dysfunction and behavioral symptoms. The first clues of organic brain disorder were multiple and severe symptoms of disinhibition resistant to treatment with dopaminergic drugs and the results of neuropsychological testing. Computed tomography, magnetic resonance imagining, and single-photon emission computed tomography findings were minor and not supported by associated neurological symptoms. However, the location of alterations of brain structure and perfusion significantly correlated with psychopathology. Clarification of the organic cause of the conduct disorder allowed choosing an effective strategy of psychopharmacologic treatment. A positive clinical effect was achieved after switching the treatment from dopaminergic antipsychotic drugs to carbamazepine, which modulates the GABAergic system. Presenting this clinical case, we intended to emphasize the importance of careful attention to the findings of neurovisual and neuropsychological testing diagnosing conduct disorders and individually choosing the most effective psychopharmacologic treatment.

    Few neoplastic diseases have undergone a transformation in a relatively short period of time like chronic myeloid leukemia (CML) has in the last few years. In 1960, CML was the first cancer where a unique chromosomal abnormality, “a minute chromosome”,1 was identified and a pathophysiologic correlation suggested. Landmark work followed, recognizing the underlying translocation between chromosomes 9 and 22 that gave rise to this abnormality2 and shortly afterward, the specific genes involved3,4 and the pathophysiologic implications of this novel rearrangement.5–7 Fast-forward a few years, this knowledge has given us the most remarkable example of a specific therapy targeting the dysregulated kinase activity represented by this molecular change. The broad use of tyrosine kinase inhibitors has resulted in an improvement in the overall survival to the point where the life expectancy of patients today is nearly equal to that of the general population.8 Still, there are challenges and unanswered questions that define the reasons why the progress still escapes many patients, and the details that separate patients from ultimate “cure”. In this manuscript we review our current understanding of CML in 2015, present recommendations for optimal management, and discuss the unanswered questions and what could be done to answer them in the near future.

    Full Text Available Recent advances in corneal graft technology, including donor tissue retrieval, storage and surgical techniques, have greatly improved the clinical outcome of corneal grafts. Despite these advances, immune mediated corneal graft rejection remains the single most important cause of corneal graft failure. Several host factors have been identified as conferring a "high risk" status to the host. These include: more than two quadrant vascularisation, with associated lymphatics, which augment the afferent and efferent arc of the immune response; herpes simplex keratitis; uveitis; silicone oil keratopathy; previous failed (rejected grafts; "hot eyes"; young recipient age; and multiple surgical procedures at the time of grafting. Large grafts, by virtue of being closer to the host limbus, with its complement of vessels and antigen-presenting Langerhans cells, also are more susceptible to rejection. The diagnosis of graft rejection is entirely clinical and in its early stages the clinical signs could be subtle. Graft rejection is largely mediated by the major histocompatibility antigens, minor antigens and perhaps blood group ABO antigens and some cornea-specific antigens. Just as rejection is mediated by active immune mediated events, the lack of rejection (tolerance is also sustained by active immune regulatory mechanisms. The anterior chamber associated immune deviation (ACAID and probably, conjunctiva associated lymphoid tissue (CALT induced mucosal tolerance, besides others, play an important role. Although graft rejection can lead to graft failure, most rejections can be readily controlled if appropriate management is commenced at the proper time. Topical steroids are the mainstay of graft rejection management. In the high-risk situations however, systemic steroids, and other immunosuppressive drugs such as cyclosporin and tacrolimus (FK506 are of proven benefit, both for treatment and prevention of rejection.

    To investigate the pathogenesis, diagnosis, and treatment of unilateral gluteal muscle contracture. Between January 1990 and September 2009, 41 patients with unilateral gluteal muscle contracture were treated and the clinical data were retrospectively analysed. Among them, 24 were male and 17 were female with an age range from 6 to 29 years (mean, 12 years). Thirty-nine patients had a definite history of repeat intragluteal injection. The locations were the left side in 9 cases and the right side in 32 cases. The main clinical manifestations included lameness and abnormal gait. The medical examination showed pelvic oblique and relative inequality of lower limbs with a mean difference of 2.1 cm (range, 1.2-3.8 cm) in the distance form navel to malleolus medials. The X-ray films of pelvis showed outpouching trochanter of femur and pelvic oblique. The CT scans showed no abnormal finding except pelvic oblique and gluteal muscle contracture. The arc longitudinal incision was made into the posterolateral area nearby the greater trochanter and then lysis of the gluteal muscles was performed, followed by the skin traction of both legs and rehabilitation exercise. All incisions healed by first intention. Forty-one patients were followed up 1-20 years (mean, 5 years), and the signs of gluteal muscle contracture disappeared. After 1 year of operation, 34 patients had equal leg length, 5 patients had mild pelvic oblique, and 2 patients had obvious pelvic oblique. According to LIU Guohui et al. evaluation standard, the results were excellent in 33 cases, good in 6 cases, and poor in 2 cases with an excellent and good rate of 95.12% at 1 year after operation. Unilateral gluteal muscle contracture leads to pelvic oblique and inequality of lower limbs, and it can be cured with the surgical release of the gluteal muscle contracture by the arc longitudinal incision into the posterolateral area nearby the greater trochanter, combined with postoperative skin traction and

    The congenital heart disease includes abnormalities in heart structure that occur before birth. Such defects occur in the fetus while it is developing in the uterus during pregnancy. About 500,000 adults have congenital heart disease in USA (WebMD, Congenital heart defects medications, www.WebMD.com/heart-disease/tc/congenital-heart-defects-medications , 2014). 1 in every 100 children has defects in their heart due to genetic or chromosomal abnormalities, such as Down syndrome. The excessive alcohol consumption during pregnancy and use of medications, maternal viral infection, such as Rubella virus, measles (German), in the first trimester of pregnancy, all these are risk factors for congenital heart disease in children, and the risk increases if parent or sibling has a congenital heart defect. These are heart valves defects, atrial and ventricular septa defects, stenosis, the heart muscle abnormalities, and a hole inside wall of the heart which causes defect in blood circulation, heart failure, and eventual death. There are no particular symptoms of congenital heart disease, but shortness of breath and limited ability to do exercise, fatigue, abnormal sound of heart as heart murmur, which is diagnosed by a physician while listening to the heart beats. The echocardiogram or transesophageal echocardiogram, electrocardiogram, chest X-ray, cardiac catheterization, and MRI methods are used to detect congenital heart disease. Several medications are given depending on the severity of this disease, and catheter method and surgery are required for serious cases to repair heart valves or heart transplantation as in endocarditis. For genetic study, first DNA is extracted from blood followed by DNA sequence analysis and any defect in nucleotide sequence of DNA is determined. For congenital heart disease, genes in chromosome 1 show some defects in nucleotide sequence. In this review the causes, diagnosis, symptoms, and treatments of congenital heart disease are described.

    In addition to genetic factors, the role of epigenetic and other environmental factors in the promotion of anxiety disorder has attracted much attention in psychiatric research. When stress is encountered in the environment, the hypothalamus-pituitary adrenal system (HPA system) is activated and cortisol is secreted. CRHR gene function is closely related to this response. As a result of haplotype analysis of CRHR genes in depression and panic disorder patients, it was found that genetic polymorphism of CRHR1 and CRHR2 was related to both disorders. It is reported that abused children are more susceptible to developing depression and anxiety disorder upon reaching adulthood, but there also exist genetic polymorphisms that may moderate this relationship. Direct methylation of DNA (typically repressing gene expression) and modification of chromatin structure (complexes of histone proteins and DNA) via acetylation (typically facilitating gene expression) represent epigenetic modifications that are thought to influence behavioral phenotypes. For example, it is rare that schizophrenia develops in identical twins brought up together in the same environment, and thus phenotypic differences cannot be explained simply by genetic polymorphism. We also evaluated salivary cortisol and amylase reactivity (indices of the HPA system and sympathoadrenal medullary system, respectfully) after electrical stimulation stress and Trier Social Stress Test (TSST) administration. Here we found differences in the cortisol stress response between electrical stimulation and TSST stressors, in contrast to the theory of Selye. In addition, we found alterations in activity patterns and difficulties integrating sensorimotor information in panic disorder patients, suggesting links between sensorimotor integration and stress in panic disorder. Moreover, state and trait anxiety may be associated with stabilograph factors.

    Full Text Available This paper considers, from the theoretical point of view, the problem of diagnosing and treatment of depressive disorders in people with intellectual disability (ID, relying primarily on the results of previous researches, which stress the etiological, symptomatic, diagnostic and therapeutic specifics when it comes to depression and its correlates in this population. The interest in mental health and psychopathology of people with ID intensified during the seventh decade of the previous century, when it became clear that some cognitive and behavioral symptoms are not, as hitherto thought, only a part or a consequence of the syndrome of intellectual disability, but a sign of ongoing mental disorder. So, the idea of ''dual diagnosis'' was born, and now it provides guidelines for the growing number of studies which theoretically and empirically review different issues of mental health problems in people with ID. Likewise, the observation of syndrome groups of genetic disorders resulting in intellectual disability has led to the narrowing of the circle of genetic syndromes that carry increased risk for the onset of depression and its correlates, such as: Down syndrome, Fragile X syndrome and Prader-Willi syndrome. Potential diagnostic problem in people with ID, when it comes to depression, may arise from ''diagnostic overshadowing’’ of depression symptoms, which often remain hidden under abnormal behavior and adjustment disorders, especially in patients with severe forms of ID. As a possible way to overcome these problems some authors have proposed the concept of ''behavioral equivalents of depression'' or behavioral disorders that evidently can be associated with depression, such as social withdrawal, aggression, hostility, irritability, psychomotor agitation or retardation. Intensification of these forms of behavior may be a sign of developing depression, and in that sense, this view represents a useful starting point. When it comes to
