    Simony, Ane; Hansen, Emil Jesper; Christensen, Steen Bach

    2016-01-01

    PURPOSE: To report the incidence of cancer in a cohort of adolescent idiopathic scoliosis (AIS) patients treated 25 years previously. METHODS: 215 consecutive AIS patients treated between 1983 and 1990 were identified and requested to return for clinical and radiographic examination. The incidence...... of cancer was determined through chart review and follow-up interviews. Using the original radiographic log file that included patient position, mAs, kV and the total number of X-rays taken, a radiation physicist calculated the total radiation dose during treatment and follow-up adjusted for BMI and sex...

    2010-01-01

    Full Text Available Juvenile idiopathic arthritis (JIA patients (n=36 with symmetrical polyarticular joint involvement of the lower extremities and healthy controls (n=20 were compared concerning differences in kinematic, kinetic, and spatio-temporal parameters with 3D gait analysis. The aims of this study were to quantify the differences in gait between JIA patients and healthy controls and to provide data for more detailed sport activities recommendations. JIA-patients showed reduced walking speed and step length, strongly anterior tilted pelvis, reduced maximum hip extension, reduced knee extension during single support phase and reduced plantar flexion in push off. Additionally the roll-off procedure of the foot was slightly decelerated. The reduced push off motion in the ankle was confirmed by lower peaks in ankle moment and power. The gait of JIA-patients can be explained as a crouch-like gait with hyperflexion in hip and knee joints and less plantar flexion in the ankle. A preventive mobility workout would be recommendable to reduce these restrictions in the future. Advisable are sports with emphasis on extension in hip, knee, and ankle plantar flexion.

    Full Text Available Scoliosis is called idiopathic when no other underlying disease can be identified. The etiology of adolescent idiopathic scoliosis (AIS is still unknown despite many years of research effort. Theories on AIS's etiology have included mechanical, hormonal, metabolic, neuromuscular, growth, and genetic abnormalities. Skeletally immature patients with adolescent idiopathic scoliosis are at risk of curve progression. The adolescent onset of severe idiopathic scoliosis has traditionally been evaluated using standing posteroanterior radiographs of the full spine to assess lateral curvature with the Cobb method. Scoliosis in children of school age and above primarily occurs in girls. The therapeutic goal in children is to prevent progression. In children, scoliosis of 20 and deg; or more should be treated with a brace, and scoliosis of 45 and deg; or more with surgery. [Arch Clin Exp Surg 2014; 3(3.000: 174-182

    2015-05-01

    Idiopathic anaphylaxis is a diagnosis of exclusion after other causes have been thoroughly evaluated and excluded. The pathogenesis of idiopathic anaphylaxis remains uncertain, although increased numbers of activated lymphocytes and circulating histamine-releasing factors have been implicated. Signs and symptoms of patients diagnosed with idiopathic anaphylaxis are indistinguishable from the manifestations of other forms of anaphylaxis. Treatment regimens are implemented based on the frequency and severity of patient symptoms and generally include the use of epinephrine autoinjectors, antihistamines, and steroids. The prognosis of idiopathic anaphylaxis is generally favorable with well-established treatment regimens and effective patient education. Copyright © 2015 Elsevier Inc. All rights reserved.

    Tsuda, Hiroko

    2017-01-01

    Idiopathic thrombosis involves a group of inherited thrombophilia predisposed to severe thrombosis of early onset and associated with an adverse outcome due to recurrence, and therefore, requires long-term anticoagulation therapy. The causative factors of a predisposition to thrombosis include immobility, dehydration, infection, surgery, injury, cancer, pregnancy, and estrogen use. The inherited deficiencies of antithrombin (AT), protein C (PC), and protein S (PS) are specified as "Specific Pediatric Chronic Diseases." However, medical expense assistance for patients terminates when they reach the age of 20 years. On April 1 st 2017, "Idiopathic Thrombosis due to Inherited Thrombophilia," consisting of inherited AT, PC, and PS deficiencies, was specified as an "Intractable Disease," and aid for medical expenses became available. Accordingly, progress in the research and practice of idiopathic thrombosis is expected in future to improve the medical care system and to construct a database via clinical surveys.

    2009-06-01

    Previously called atypical facial pain, persistent idiopathic facial pain (PIFP) is a common, but poorly defined entity. The cause of PIFP is unknown, but surgery or injury in the distribution of the trigeminal nerve could be reported as early event. Treatment is often unsatisfactory and quality research relating management of this condition is missing. Psychologi-cal distress is frequently observed in patients suffering from persistent idiopathic facial pain. The present review aims at presenting the available knowledge of this elusive orofacial pain condition.

    Idiopathic oedema is a non-inflammatory interstitial oedema seen in fertile women. A hallmark is a daily increase in weight > 1.4 kg from morning until evening due to fluid retention, which shows as facial puffiness in the morning and more often abdominal increase and swollen lower extremities...... during the day. Patients may be disabled due to accompanying symptoms like headache, dizziness, fatigue, anxiety, and depression. The diagnosis is based on clinical features and exclusion of other causes of oedema. Non-pharmacological interventions and pharmacological therapies are reviewed....

  10. Idiopathic Scoliosis

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available Idiopathic scoliosis (IS is a lifetime condition and is defined as a structural, lateral rotated curvature of the spine of >10° on standing coronal plane radiographs. It should be distinguished from other causes of scoliosis. It can be classified as infantile, juvenile, and adolescent according to age. As a rule of thumb, about 80% of all curves are idiopathic, right convex thoracic, and present in otherwise healthy girls at the beginning of puberty. A family member most commonly detects scoliosis. The structural asymmetry of the spine is best observed by asking the patient to bend forward. IS is often seen in more than one member of a family, but the aetiology remains unknown. Multiple genes are likely to be involved with incomplete penetrance and variable expressivity. Early detection by screening allows for monitoring curve progression and timely initiation of bracing, but school screening is controversial and practises vary worldwide. Most patients have minor scoliosis and treatment is generally not recommended for patients with curves 45°. Scoliosis surgery was not successful until the introduction of Harrington’s instrumentation in the 1960s. Modern instrumentation has evolved from the Cotrel-Dubousset system in the 1980s, and a variety of methods are available today. Although scoliosis may be a burden, long-term studies suggest that a good quality of life is maintained in most patients.

    2014-04-01

    Idiopathic hemihypertrophy is a congenital overgrowth disorder associated with an augmented risk for embryonal tumors. We present 4 cases of hemihypertrophy in Yemeni children living in Sana`a city. They presented to the outpatient clinics in a private hospital in Sana`a city, Yemen, over a period of 3 years from January 2009 to December 2011. The first 2 cases had no complaints apart from asymmetrical size of one side of their bodies (left side hemihypertrophy). The third case presented with left side hemihypertrophy and an abdominal mass, which upon referral to a cancer center was confirmed to be Wilms` tumor. The fourth case had overgrowth of the right leg and foot with polydactyly, and a right sided abdominal mass. He was diagnosed to have an ureteropelvic junction stricture with hydronephrosis and absent left kidney.

  12. Idiopathic epileptic syndromes and cognition.

    2006-01-01

    Epilepsy is frequently associated with cognitive impairments which result from various interacting factors. The present paper deals with the contribution of neuropsychology to the characterization of the type of epilepsy and the possible mechanisms underlying idiopathic epileptic syndromes. The non-lesional, so-called idiopathic epilepsies, constitute an interesting model for assessing the relationship between epileptiform EEG discharges and cognition. Among the idiopathic generalized epilepsies, disorders of social integration and personality have been frequently reported in juvenile myoclonic epilepsy (JME). Since similar disturbances are observed in frontal-lobe-lesioned patients, impairments in other frontal lobe functions (e.g. executive functions) might be expected in JME. This gives rise to speculation about the possible underlying pathophysiological mechanisms in JME. With regard to partial idiopathic epilepsies, benign childhood epilepsy with centrotemporal spikes (BCECTS) may provide a useful model for the study of the relationship between epileptiform EEG discharges in the peri-sylvian region and language functions. Furthermore, the description of mild cognitive dysfunctions in BCECTS, and their persistence into adulthood, can provide information about compensatory mechanisms and may allow for the generation of remedial strategies. Thus, 'lesional' neuropsychology has given way to 'dynamic' neuropsychology based on specific postulates. By using the cognitive profile to specify the mechanism underlying the behavioral disturbances observed in different types of epilepsy, neuropsychology may eventually contribute to a revision of the present classification of epileptic syndromes. In addition, the neuropsychological data may help predict the extent and limits of functional recovery and cerebral plasticity.

    Dunnigan, M. G.; Denning, D. W.; Henry, J. A.; de Wolff, F. A.

    1987-01-01

    Diuretic abuse has been invoked as the cause of idiopathic oedema. In this study, eight patients with idiopathic oedema were studied. Symptoms and weight variation continued despite the proven absence of diuretics in seven of them as determined by urinary chromatograms. Idiopathic oedema cannot therefore be attributed to diuretic use alone. PMID:3671223

    To describe the radiologic findings of idiopathic portal hypertension and to find the points of differentiation between idiopathic portal hypertension and liver cirrhosis. Four portograms in five patients who for four years had suffered from pathologically confirmed idiopathic portal hypertension were retrospectively analyzed and compared with a portogram obtained from a control subject with liver cirrhosis. Portographic finding s of idiopathic portal hypertension were paucity of medium-sized portal branches, irregular and obtuse-angled division of peripheral branches, abrupt interruption and an avascular area beneath the liver margin. A portogram of idiopathic portal hypertension may be useful in differentiation this and liver cirrhosis

    Idiopathic hypogonadotropic hypogonadism, which may be associated with anosmia (the Kallmann syndrome) or with a normal sense of smell, is a treatable form of male infertility caused by a congenital defect in the secretion or action of gonadotropin-releasing hormone (GnRH). Patients have absent or incomplete sexual maturation by the age of 18. Idiopathic hypogonadotropic hypogonadism was previously thought to require lifelong therapy. We describe 15 men in whom reversal of idiopathic hypogonadotropic hypogonadism was sustained after discontinuation of hormonal therapy. We defined the sustained reversal of idiopathic hypogonadotropic hypogonadism as the presence of normal adult testosterone levels after hormonal therapy was discontinued. Ten sustained reversals were identified retrospectively. Five sustained reversals were identified prospectively among 50 men with idiopathic hypogonadotropic hypogonadism after a mean (+/-SD) duration of treatment interruption of 6+/-3 weeks. Of the 15 men who had a sustained reversal, 4 had anosmia. At initial evaluation, 6 men had absent puberty, 9 had partial puberty, and all had abnormal secretion of GnRH-induced luteinizing hormone. All 15 men had received previous hormonal therapy to induce virilization, fertility, or both. Among those whose hypogonadism was reversed, the mean serum level of endogenous testosterone increased from 55+/-29 ng per deciliter (1.9+/-1.0 nmol per liter) to 386+/-91 ng per deciliter (13.4+/-3.2 nmol per liter, Phypogonadotropic hypogonadism and the Kallmann syndrome was noted after discontinuation of treatment in about 10% of patients with either absent or partial puberty. Therefore, brief discontinuation of hormonal therapy to assess reversibility of hypogonadotropic hypogonadism is reasonable. (ClinicalTrials.gov number, NCT00392756 [ClinicalTrials.gov].).

    Recurrent or chronic pulmonary hemorrhage is rare in children. Idiopathic pulmonary hemosiderosis (IPH) manifests as hemoptysis, diffuse parenchymal infiltrates on chest radiographs and microcytic hypochromic anemia. The hemoptysis present may be mistaken for more common diseases, delaying the diagnosis and further management. Idiopathic pulmonary hemosiderosis is a disorder of unknown etiology. Treatment of IPH includes immunosuppressive drugs along with supportive measures.

    To describe 2 topographic facial pain conditions with the pain clearly localized in the eye (idiopathic ophthalmodynia) or in the nose (idiopathic rhinalgia), and to propose their distinction from persistent idiopathic facial pain. Persistent idiopathic facial pain, burning mouth syndrome, atypical odontalgia, and facial arthromyalgia are idiopathic facial pain syndromes that have been separated according to topographical criteria. Still, some other facial pain syndromes might have been veiled under the broad term of persistent idiopathic facial pain. Through a 10-year period we have studied all patients referred to our neurological clinic because of facial pain of unknown etiology that might deviate from all well-characterized facial pain syndromes. In a group of patients we have identified 2 consistent clinical pictures with pain precisely located either in the eye (n=11) or in the nose (n=7). Clinical features resembled those of other localized idiopathic facial syndromes, the key differences relying on the topographic distribution of the pain. Both idiopathic ophthalmodynia and idiopathic rhinalgia seem specific pain syndromes with a distinctive location, and may deserve a nosologic status just as other focal pain syndromes of the face. Whether all such focal syndromes are topographic variants of persistent idiopathic facial pain or independent disorders remains a controversial issue.

  18. [Idiopathic autonomic neuropathy (pandysautonomia)].

    Science.gov (United States)

    Jankowicz, E; Drozdowski, W; Pogumirski, J

    2001-01-01

    On the basis of current literature, clinical and neuropathologic features of idiopathic autonomic neuropathy is presented. Idiopathic autonomic neuropathy is a disease characterized by acute or subacute onset, monophasic course over a period of several years, it is often preceded by an infection. The spectrum of autonomic changes ranges from cholinergic or adrenergic dysfunction to pandysautonomia, leading to heterogeneity of its clinical features. Possible sympathetic system abnormalities found in autonomic neuropathy are: poor pupillary response to light in darkness, orthostatic hypotension leading to syncope, hypotension without compensatory tachycardia, ejaculation disturbances and vasomotor instability. Possible parasympathetic dysfunctions are: salivation and lacrimation disturbances, absent pupillary constriction to light and near gaze, gastrointestinal tract immobility and impairment of gastrointestinal function, atonic bladder with large residual volume, erectile impotence. Pandysautonomia is thought to result from an immune mediated mechanism and responds well to plasmaferesis and intravenous immunoglobin therapy leading to gradual, sometimes not full, recovery. Moreover in this article we pay attention to the clinical value of many tests like cardiovascular or pharmacological studies in the diagnosis of pandysautonomia and in differentiation of pre- and postganglionic changes. In order to diagnose idiopathic autonomic neuropathy one has to rule out a large number of diseases with autonomic dysfunction e.g.: diabetes, malignant neoplasms, acute intermittent porphyria, Shy-Drager syndrome, Riley-Day's dysautonomia, Parkinson's disease, amyloidosis and others.

    Idiopathic hypoparathyroidism (IHP) is a rare endocrinopathic disorder, of idiopathic nature, characterized by a deficiency of parathyroid hormone causing low serum calcium (Ca) and high serum phosphorus concentrations. We present a case report ofa 40-year-old woman with complaint of bleeding gums and tingling sensation in fingers and toes reported to our department in March 2005 with no tangible diagnosis from previous medical examinations. Oral findings included abnormally short roots, cemental hyperplasia, widening of the periodontal ligament space and root resorption. Laboratory investigations revealed a low serum Ca level and along with the clinical findings, a diagnosis of IHP was reached. Oral prophylaxis was performed and Ca supplements were prescribed. We believe that this case report is a first of its kind reporting cemental hyperplasia, altered alveolar bone patterns and periodontal ligament widening in a patient with IHP.

Laboratory investigations revealed a low serum Ca level and along with the clinical findings, a diagnosis of IHP was reached. Oral prophylaxis was performed and Ca supplements were prescribed. We believe that this case report is a first of its kind reporting cemental hyperplasia, altered alveolar bone patterns and periodontal ligament widening in a patient with IHP.

    Full Text Available Chronic pain after dental implantation is rare but difficult issue for the implant practitioner. Patients with chronic pain who had been performed previous implant surgery or related surgical intervention sometimes accompany with psychological problem and difficult to adequately manage. According to the International Classification of Headache Disorders (ICHD 3rd eds, Cepalagia 2013, painful neuropathies and other facial pains are subdivided into the 12 subcategories; 13.1. Trigeminal neuralgia; 13.2 Glossopharyngeal neuralgia; 13.3 Nervus intermedius (facial nerve neuralgia; 13.4 Occipital neuralgia; 13.5 Optic neuritis; 13.6 Headache attributed to ischaemic ocular motor nerve palsy; 13.7 Tolosa-Hunt syndrome; 13.8 Paratrigeminal oculo-sympathetic (Raeder’s syndrome; 13.9 Recurrent painful ophthalmoplegic neuropathy; 13.10 Burning Mouth Syndrome (BMS; 13.11 Persistent Idiopathic Facial Pain (PIFP; 13.12 Central neuropathic pain. Chronic orofacial pain after dental implant surgery can be largely into the two main categories that can be frequently encountered in clinical basis ; 1 Neuropathic pain, 2 Idiopathic pain. If there is no direct evidence of the nerve injury related with the implant surgery, the clinician need to consider the central cause of pain instead of the peripheral cause of the pain. There might be several possibilities; 1 Anaesthesia dolorosa, 2 Central post-stroke pain, 3 Facial pain attributed to multiple sclerosis, 4 Persistent idiopathic facial pain (PIFP, 5 Burning mouth syndrome. In this presentation, Persistent idiopathic facial pain (PIFP, the disease entity that can be frequently encountered in the clinic would be discussed. Persistent idiopathic facial pain (PIFP can be defined as “persistent facial and/or oral pain, with varying presentations but recurring daily for more than 2 hours per day over more than 3 months, in the absence of clinical neurological deficit”. ‘Atypical’ pain is a diagnosis of

    There is scant information about the management of idiopathic megarectum in childhood. Children with idiopathic megarectum referred to a single institution between 1994 and 1998 were identified prospectively. Those with Hirschsprung's disease or an anorectal malformation were excluded. The remaining patient group, 22 boys and 7 girls, had a median age of 8.0 years (range 3.5-14.0 y). Median duration of symptoms prior to referral was 2.0 years (range 0.4-11 y). Chronic soiling was the dominant complaint in 28/29 (97%) cases. 23 children had received regular stimulant laxatives for periods ranging from 1 month to 11 years, and 9 children had been treated with regular enemas. The degree of megarectum assessed by both abdominal palpation and plain radiography was: grade 1 (below umbilical level) n=6; grade 2 (at umbilical level) n=15; and grade 3 (above umbilical level) n=8. Hirschsprung's disease was specifically excluded by rectal biopsy in all cases and no patient had evidence of spinal dysraphism. Three boys with massive megarectums and intractable symptoms were treated by a staged Duhamel sigmoid pull-through with excellent functional results. Fifteen patients (52%) were treated by a single manual evacuation under general anaesthesia followed by a daily Bisacodyl 5-10 mg suppository. After a median follow-up of 16 months, 13 continue to respond well with a daily bowel action and no soiling (4 of the 13 have discontinued treatment and remain well). The remaining 11 patients (38%) have continued conventional treatment with oral laxatives but with limited success. Idiopathic megarectum is poorly described in children. It is more common in boys and is often resistant to laxative therapy alone. After appropriate preparation, treatment with stimulant suppositories can be effective. Surgery has a valuable role in selected patients with a massive megarectum.

    Full Text Available Growth is a complex process and the basic characteristic of child- hood growth monitoring provides insight into the physiological and pathological events in the body. Statistically, the short stature means departure from the values of height for age and sex (in a particular environment, which is below -2 standard deviation score, or less than -2 standard deviation, i.e. below the third percentile. Advances in molecular genetics have contributed to the improvement of diagnostics in endocrinology. Analysis of patients’ genotypes should not be performed before taking a classical history, detailed clinical examination and appropriate tests. In patients with idiopathic short stature specific causes are excluded, such as growth hormone deficiency, Turner syndrome, short stature due to low birth weight, intrauterine growth retardation, small for gestational age, dysmorphology syndromes and chronic childhood diseases. The exclusion of abovementioned conditions leaves a large number of children with short stature whose etiology includes patients with genetic short stature or familial short stature and those who are low in relation to genetic potential, and who could also have some unrecognized endocrine defect. Idiopathic short stature represents a short stature of unknown cause of heterogeneous etiology, and is characterized by a normal response of growth hormone during stimulation tests (>10 ng/ml or 20 mJ/l, without other disorders, of normal body mass and length at birth. In idiopathic short stature standard deviation score rates <-2.25 (-2 to -3 or <1.2 percentile. These are also criteria for the initiation of growth hormone therapy. In children with short stature there is also the presence of psychological and social suffering. Goals of treatment with growth hormone involve achieving normal height and normal growth rate during childhood.

    Idiopathic pulmonary hemosiderosis is a rare condition manifested by recurrent pulmonary hemorrhage of unknown cause, diffuse radiologic abnormalities, cough, hemoptysis and moderate to severe hypochromic anemia. Diagnosis can be confirmed by iron stains of the sputum or lung aspiration or by biopsy. Prolonged spontaneous remission may occur without the use of corticosteroid therapy. Studies here reported indicated that the anemia is hypochromic and microcytic anemia of blood loss and iron deficiency, in spite of the presence of large amounts of iron in the pulmonary tissue. Correction of the anemia by intensive iron therapy and transfusion is considered an important part of therapy. ImagesFigure 1.Figure 2.Figure 3. PMID:13787318

    Idiopathic epiretinal membrane (iERM) is very rare in adolescent patients. The pathogenesis remains unclear although the role of hyalocytes is of major importance. The clinical features in young patients are different from those in older patients. We describe a case of iERM in a 15-year-old girl who presented with metamorphopsia of the right eye. This case report presents the basis for the decision for surgical treatment as well as the clinical features at follow-up examination 9 months after surgery.

    2008-01-01

    Gamma knife radiosurgery (GKS) has been generally considered as a viable therapeutic option for the management of medically refractory idiopathic trigeminal neuralgia (TN). We reviewed our experience with GKS in patients with TN. Between Feb 1996 and May 2006. 77 patients with medical refractory idiopathic TN were treated using GKS. Thirty-six patients who had undergone other previous procedures, previous GKS, or had brain stem lesion, atypical symptoms, were excluded from this study. Pain improvement was achieved in 38 of the patients with TN (pain response rate 92.7 %). Twenty-three patients were pain free and 15 had reduced pain. There were no serious complications. We think that GKS is an effective treatment option for patients with medical refractory idiopathic TN. (author)

    Full Text Available In a scenario of inbound call center customer service, the ability to forecast calls is a key element and advantage. By forecasting the correct number of calls a company can predict staffing needs, meet service level requirements, improve customer satisfaction, and benefit from many other optimizations. This project will show how elementary statistics can be used to predict calls for a specific company, forecast the rate at which calls are increasing/decreasing, and determine if the calls may stop at some point.

    Objective To investigate the perinatal outcomes of cases with idiopathic polyhydramnios. Study Design Retrospective analysis of 160 singleton pregnancies that were under routine surveillance at the department of obstetrics from 2008 to 2010 was performed to assess perinatal outcomes. Finally, 59 cases were included as idiopathic polyhydramnios, and 101 cases were included as controls. Preterm delivery (4000 g), 1- and 5-min APGAR scores polyhydramnios group compared with the control group. Conclusion Although perinatal outcomes are conflicting in literature, idiopathic polyhydramnios warrants close surveillance especially near term. PMID:24265884

    2014-01-01

    Full Text Available Our aim was to clarify the correlation of attention deficit hyperactivity disorder (ADHD with epilepsy and behavior problems. This was a cross-sectional study. Sixty children with idiopathic epilepsy were interviewed using the MTA-SNAP IV Teacher and Parent Rating Scale, Vineland Adaptive Behavior Scales and Conners’ Rating Scales. We used the chi-square test to analyze the correlation of epilepsy variables in patients with and without ADHD with a significance level of 0.05. Eight patients had ADHD symptoms (13%, seven had the inattentive ADHD subtype and only three had behavioral problems. When epileptic patients with and without ADHD symptoms were compared we found no significant difference in regard to epilepsy variables. All patients were controlled and 43% were either without AED or undergoing withdrawal. Our study revealed a low comorbidity of ADHD symptoms and epilepsy due to low interference of seizures and drug treatment on the comorbid condition.

    2014-01-01

    Full Text Available Idiopathic thrombocytopenic purpura (ITP is defined as a hematologic disorder, characterized by isolated thrombocytopenia without a clinically apparent cause. The major causes of accelerated platelet consumption include immune thrombocytopenia, decreased bone marrow production, and increased splenic sequestration. The clinical presentation may be acute with severe bleeding, or insidious with slow development with mild or no symptoms. The initial laboratory tests useful at the first visit to predict future diagnosis were erythrocyte count, leukocyte count, anti-glycoprotein IIb/IIIa antibodies, reticulated platelets, plasma thrombopoietin level. Treatment should be restricted to those patients with moderate or severe thrombocytopenia who are bleeding or at risk of bleeding. We present a case report on ITP with clinical presentation, diagnosis and management.

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    2011-11-01

    Idiopathic pulmonary fibrosis (IPF) is the most common of the idiopathic interstitial pneumonias. Despite multiple recent clinical trials, there is no strong evidence supporting a survival advantage for any agent in the management of patients with IPF. The limited effectiveness of current treatment regimes has led to a search for novel therapies including antifibrotic strategies. This article reviews the evidence supporting the treatments currently used in the management of IPF.

    Takeuchi, Kenzen; Azegami, Hideyuki; Murachi, Shunji; Kitoh, Junzoh; Ishida, Yoshito; Kawakami, Noriaki; Makino, Mitsunori

    A hypothesis that the thoracic idiopathic scoliosis is buckling phenomenon of the fourth mode induced by the growth of thoracic vertebral bodies was presented in the previous work by the authors using numerical simulations with finite element model of the spine. If the hypothesis is acceptable, sensitivity function with respect to the critical growth of thoracic vertebrae on the maximization problem of buckling load with the fourth buckling mode gives us useful information to improve and develop treatments for the idiopathic scoliosis. The numerical results analyzed by the finite element method demonstrated that the sensitivity function is high at the articular capsules of the intervertebral joints, the intervertebral disks, the costotransverse joints and the constovertebral joints around the apex of the curvature in the case of the thoracic idiopathic scoliosis.

    Henderson, L; Farrelly, P; Dickson, A P; Goyal, A

    2016-02-01

    Williams and Mikhael (1971) described idiopathic urethritis (IU) as a self-limiting condition that affects boys aged 5-15 years, with symptoms of urethrorrhagia, dysuria and haematuria. However, a proportion of boys will remain symptomatic for several years, and may develop urethral stricture (Poch et al., 2007; Palagiri et al., 2003). There is no universally effective treatment for IU, although various strategies have been employed. To review the presentation and long-term outcomes of boys with IU, and present the efficacy of management strategies that have been utilised. A retrospective review was performed of all boys with IU. It was based on clinical and cystoscopic findings for presentation, medical history, management and clinical progress. Fifty-four boys were included, with a median age of 11 years (range 5-15 years) at presentation. The median duration of symptoms was 18 months (range 2-132 months). The median follow-up was 18.5 months (range 1-120 months). Seven (13.0%) boys had early urethral stricture at initial cystourethroscopy, and one (1.9%) developed stricture during follow-up. Thirty-six boys (66.7%) had previous circumcision and four (7.4%) had meatal stenosis. Eight (14.8%) had previous hypospadias repair. Whilst 50% of boys with IU do not require any specific treatment, those with severe/unremitting symptoms may benefit from a trial of urethral steroids or short-term urethral catheterisation. The mechanisms of benefit from these modalities are unclear and they require further evaluation. Copyright © 2015 Journal of Pediatric Urology Company. Published by Elsevier Ltd.

    Full Text Available Abstract Idiopathic pulmonary fibrosis (IPF is a non-neoplastic pulmonary disease that is characterized by the formation of scar tissue within the lungs in the absence of any known provocation. IPF is a rare disease which affects approximately 5 million persons worldwide. The prevalence is estimated to be slightly greater in men (20.2/100,000 than in women (13.2/100,000. The mean age at presentation is 66 years. IPF initially manifests with symptoms of exercise-induced breathless and dry coughing. Auscultation of the lungs reveals early inspiratory crackles, predominantly located in the lower posterior lung zones upon physical exam. Clubbing is found in approximately 50% of IPF patients. Cor pulmonale develops in association with end-stage disease. In that case, classic signs of right heart failure may be present. Etiology remains incompletely understood. Some environmental factors may be associated with IPF (cigarette smoking, exposure to silica and livestock. IPF is recognized on high-resolution computed tomography by peripheral, subpleural lower lobe reticular opacities in association with subpleural honeycomb changes. IPF is associated with a pathological lesion known as usual interstitial pneumonia (UIP. The UIP pattern consists of normal lung alternating with patches of dense fibrosis, taking the form of collagen sheets. The diagnosis of IPF requires correlation of the clinical setting with radiographic images and a lung biopsy. In the absence of lung biopsy, the diagnosis of IPF can be made by defined clinical criteria that were published in guidelines endorsed by several professional societies. Differential diagnosis includes other idiopathic interstitial pneumonia, connective tissue diseases (systemic sclerosis, polymyositis, rheumatoid arthritis, forme fruste of autoimmune disorders, chronic hypersensitivity pneumonitis and other environmental (sometimes occupational exposures. IPF is typically progressive and leads to significant

    Abstract Rationale: Idiopathic hypoparathyroidism (IHP) is a rare endocrine condition, which is frequently represented by neuropsychiatric disorders. Hence, the misdiagnosis rate of the disease is rather high, especially for neurologists. Patient concerns: We reported a case of misdiagnosed, atypical IHP. In addition, the literature on IHP and the misdiagnosis published in China in the past 2 decades has been reviewed and summarized. Diagnoses: Blood testing confirmed that parathyroid hormone (PTH) = 0 pg/mL and the final diagnosis was IHP. Interventions and outcomes: With calcium and vitamin D supplementation, the patient's myasthenia improved significantly, and muscle enzymes returned to normal gradually. One-year follow-up demonstrated that the patient's myasthenia disappeared, and the blood calcium and PTH levels were normal. In addition, the literature on IHP and the misdiagnosis published in China in the past 2 decades has been reviewed and summarized. Lessons: The misdiagnosis rate of IHP in China was high in the past 2 decades, which might be attributed to the misdiagnosis as epilepsy or mental diseases. A clinician should be able to understand the disease and emphasize the screening of high-risk population, especially for those patients with hypocalcemia, hyperphosphatemia, and increased blood creatine kinase with unknown causes or nontypical clinical symptoms.

    2010-09-01

    Full Text Available A 34-year-old female presented with sudden onset of severe abdominal pain in a flank distribution. A large mass was palpable in the right upper quadrant on physical examination. Abdominal contrast-enhanced computed tomography showed a well-defined, right-sided, retroperitoneal cystic lesion located between the abdominal aorta and the inferior vena cava (IVC. The tumor size was 55 × 58 mm, and it compressed the gallbladder and the duodenum. Upper gastrointestinal radiography revealed a stricture of the second portion of the duodenum by the tumor. T2-weighted magnetic resonance imaging showed that the whole part was hyperintense with hypointense rims, but the inner was partially hypointense. Based on the radiological findings, the preoperative differential diagnosis included retroperitoneal teratoma, Schwannoma, abscess, and primary retroperitoneal tumor. On laparotomy, the tumor was located in the right retroperitoneal cavity. Kocher maneuver and medial visceral rotation, which consists of medial reflection of the upper part of right colon and duodenum by incising their lateral peritoneal attachments, were performed. Although a slight adhesion to the IVC was detected, the tumor was removed safely. Thin-section histopathology examination detected neither tumor tissues nor any tissues such as adrenal gland, ovarian tissue, or endometrial implants. The final pathological diagnosis was idiopathic retroperitoneal hematoma; the origin of the bleeding was unclear. The patient was discharged without any complication 5 days after the operation.

    Benoliel, Rafael; Gaul, Charly

    2017-06-01

    Background Persistent idiopathic facial pain (PIFP) is a chronic disorder recurring daily for more than two hours per day over more than three months, in the absence of clinical neurological deficit. PIFP is the current terminology for Atypical Facial Pain and is characterized by daily or near daily pain that is initially confined but may subsequently spread. Pain cannot be attributed to any pathological process, although traumatic neuropathic mechanisms are suspected. When present intraorally, PIFP has been termed 'Atypical Odontalgia', and this entity is discussed in a separate article in this special issue. PIFP is often a difficult but important differential diagnosis among chronic facial pain syndromes. Aim To summarize current knowledge on diagnostic criteria, differential diagnosis, pathophysiology and management of PIFP. Methods We present a narrative review reporting current literature and personal experience. Additionally, we discuss and differentiate the common differential diagnoses associated with PIFP including traumatic trigeminal neuropathies, regional myofascial pain, atypical neurovascular pains and atypical trigeminal neuropathic pains. Results and conclusion The underlying pathophysiology in PIFP is still enigmatic, however neuropathic mechanisms may be relevant. PIFP needs interdisciplinary collaboration to rule out and manage secondary causes, psychiatric comorbidities and other facial pain syndromes, particularly trigeminal neuralgia. Burden of disease and psychiatric comorbidity screening is recommended at an early stage of disease, and should be addressed in the management plan. Future research is needed to establish clear diagnostic criteria and treatment strategies based on clinical findings and individual pathophysiology.

    Adolescent idiopathic scoliosis is the most common type of spinal deformity whose aetiology remains unclear. Studies suggest that gravitational forces in the standing position play an important role in scoliosis progression, therefore anthropometric data is required to develop biomechanical models of the deformity. Few studies have analysed the trunk by vertebral level and none have performed investigations of the scoliotic trunk. The aim of this study was to determine the centroid, thickness, volume and estimated mass, for sections of the scoliotic trunk. Existing low-dose CT scans were used to estimate vertebral level-by-level torso masses for 20 female adolescent idiopathic scoliosis patients. ImageJ processing software was used to analyse the CT images and enable estimation of the segmental torso mass corresponding to each vertebral level. The patients' mean age was 15.0 (SD 2.7) years with mean major Cobb angle of 52 (SD 5.9)° and mean patient weight of 58.2 (SD 11.6) kg. The magnitude of torso segment mass corresponding to each vertebral level increased by 150% from 0.6kg at T1 to 1.5kg at L5. Similarly, segmental thickness from T1-L5 increased inferiorly from a mean 18.5 (SD 2.2) mm at T1 to 32.8 (SD 3.4) mm at L5. The mean total trunk mass, as a percentage of total body mass, was 27.8 (SD 0.5) % which was close to values reported in previous literature. This study provides new anthropometric reference data on segmental (vertebral level-by-level) torso mass in adolescent idiopathic scoliosis patients, useful for biomechanical models of scoliosis progression and treatment.

    To determine the relationship between idiopathic polyhydramnios and fetal gender in the absence of fetal or maternal abnormalities. This was a retrospective population-based register study. 295 women with singleton pregnancies complicated by idiopathic polyhydramnios (amniotic fluid index (AFI) higher than 24 cm) who were delivered at our institution from January 2002 till December 2012 were included. Only pregnancies with an uncomplicated outcome were accepted in this study. The incidence of the male to female fetuses was compared with the one in the general population. Among pregnancies complicated by idiopathic polyhydramnios, the following gender distribution was found: 72.9% male and 37.1% female. The distribution in the general population was 51.5% female and 48.5% male. The mean AFI was significantly increased in male fetuses (p polyhydramnios is more frequent in male normal fetuses than in female ones.

    The glymphatic system has in previous studies been shown as fundamental to clearance of waste metabolites from the brain interstitial space, and is proposed to be instrumental in normal ageing and brain pathology such as Alzheimer's disease and brain trauma. Assessment of glymphatic function using magnetic resonance imaging with intrathecal contrast agent as a cerebrospinal fluid tracer has so far been limited to rodents. We aimed to image cerebrospinal fluid flow characteristics and glymphatic function in humans, and applied the methodology in a prospective study of 15 idiopathic normal pressure hydrocephalus patients (mean age 71.3 ± 8.1 years, three female and 12 male) and eight reference subjects (mean age 41.1 + 13.0 years, six female and two male) with suspected cerebrospinal fluid leakage (seven) and intracranial cyst (one). The imaging protocol included T1-weighted magnetic resonance imaging with equal sequence parameters before and at multiple time points through 24 h after intrathecal injection of the contrast agent gadobutrol at the lumbar level. All study subjects were kept in the supine position between examinations during the first day. Gadobutrol enhancement was measured at all imaging time points from regions of interest placed at predefined locations in brain parenchyma, the subarachnoid and intraventricular space, and inside the sagittal sinus. Parameters demonstrating gadobutrol enhancement and clearance in different locations were compared between idiopathic normal pressure hydrocephalus and reference subjects. A characteristic flow pattern in idiopathic normal hydrocephalus was ventricular reflux of gadobutrol from the subarachnoid space followed by transependymal gadobutrol migration. At the brain surfaces, gadobutrol propagated antegradely along large leptomeningeal arteries in all study subjects, and preceded glymphatic enhancement in adjacent brain tissue, indicating a pivotal role of intracranial pulsations for glymphatic function.

    Idiopathic intracranial hypertension (IIH) is a condition of yet unknown aetiology affecting predominantly obese females of childbearing age. IIH is a diagnosis of exclusion as raised cerebrospinal fluid pressure may occur secondary to numerous other medical conditions. An atypical phenotype...... or an atypical disease course should alert the physician to reevaluate a presumed IIH-diagnosis. The authors report a case of a 32-year-old non-obese male with intracranial hypertension, secondary to a syphilitic central nervous system infection, initially misdiagnosed as being idiopathic.

    Several reports of coccygodynia have been confined to the causes, the methods of treatment, and the methods of radiological examination. As far as we know, there has been no previous study about the objective measurement of the coccyx. The purpose of this study was to find the possible cause of idiopathic coccygodynia by comparing the clinical and radiological differences between traumatic and idiopathic coccygodynia by innovative objective clinical and radiological measurements. Thirty-two patients with coccygodynia were evaluated retrospectively. We divided the patients into two groups. Group 1 consisted of 19 patients with traumatic coccygodynia and group 2 consisted of 13 patients with idiopathic coccygodynia. We reviewed medical records and checked age, sex distribution, symptoms, and treatment outcome in each group. We also reviewed coccyx AP and lateral views of plain radiological film and measured the number of coccyx segments and the intercoccygeal angle in each group. The intercoccygeal angle devised by the authors was defined as the angle between the first and last segment of the coccyx. We also checked the intercoccygeal angle in a normal control group, which consisted of 18 women and 2 men, to observe the reference value of the intercoccygeal angle. The outcome of treatment was assessed by a visual analogue scale based on the pain score. Statistical analysis was done with Mann-Whitney U test and Chi-square test. Group 1 consisted of 1 male and 18 female patients, while group 2 consisted of 2 male and 11 female patients. There were no statistically significant differences between the traumatic and idiopathic coccygodynia groups in terms of age (38.7 years versus 36.5 years), male/female sex ratio (1/18 versus 2/11), and the number of coccyx segments (2.9 versus 2.7). There were significant differences between the traumatic and idiopathic coccygodynia groups in terms of the pain score (pain on sitting: 82 versus 47, pain on defecation: 39 versus 87), the

    Precision medicine is defined by the National Institute of Health's Precision Medicine Initiative Working Group as an approach to disease treatment that takes into account individual variability in genes, environment, and lifestyle. There has been increased interest in applying the concept of precision medicine to idiopathic pulmonary fibrosis, in particular to search for genetic and molecular biomarker-based profiles (so called endotypes) that identify mechanistically distinct disease subgroups. The relevance of precision medicine to idiopathic pulmonary fibrosis is yet to be established, but we believe that it holds great promise to provide targeted and highly effective therapies to patients. In this manuscript, we describe the field's nascent efforts in genetic/molecular endotype identification and how environmental and behavioral subgroups may also be relevant to disease management.

    1998-01-01

    The present paper introduces a new concept in the physiopathology and treatment of the called "temporomandibular disfunction". This paper was divided into two parts, the first explained the definition, etiology and hypothesis of the idiopathic facial pain. In this second part, its treatment, prognosis and recommendations are explained. The treatment consists basically in counselling, and, in a second stage, the use of tricylic antidepressants or similar drugs is used. Occlusal devices are some times used, but have been of less value. Arthroscopy can be used in resistant patients, and surgery is usually not indicated. The present management is based on a working model developed in this department and in other world centres, and is revolutionising the clinical management of the patients with idiopathic facial pain.

Case-control study was conducted in 500 pregnant women with idiopathic polyhydramnios (study group) and 500 normal pregnant women (control group) attending the outpatient department of SHKM Medical College, Haryana. Perinatal outcomes were recorded in both the groups. Out of 500 cases with idiopathic polyhydramnios, maximum cases were diagnosed between 28 and 36 weeks of pregnancy (84.6 %), and maximum presented with mild polyhydramnios (82 %). In the study and control groups, there were no statistically significant differences in preeclampsia and gestational hypertension (p = 0.445 and p = 0.230). In the study and control groups, 74.6 and 79.6 % women, respectively, had normal vaginal delivery (p = 0.250). The study group recorded much higher number of preterm deliveries than the control group (54 %) (p = 0.000). In the study group, 51.8 % women had maternal complications, while in the control group, 13.6 % women had obstetrical complications. The study group recorded higher perinatal mortality (10.4 %) than the control group. Idiopathic polyhydramnios is associated with higher perinatal morbidity and mortality than normal pregnancy.

    Full Text Available Following the abdominal surgery, extensive adhesions often occur and they can cause difficulties during laparoscopic operations. However, previous laparotomy is not considered to be a contraindication for laparoscopy. The aim of this study is to present that an insertion of Veres needle in the region of umbilicus is a safe method for creating a pneumoperitoneum for laparoscopic operations after previous laparotomy. In the last three years, we have performed 144 laparoscopic operations in patients that previously underwent one or two laparotomies. Pathology of digestive system, genital organs, Cesarean Section or abdominal war injuries were the most common causes of previouslaparotomy. During those operations or during entering into abdominal cavity we have not experienced any complications, while in 7 patients we performed conversion to laparotomy following the diagnostic laparoscopy. In all patients an insertion of Veres needle and trocar insertion in the umbilical region was performed, namely a technique of closed laparoscopy. Not even in one patient adhesions in the region of umbilicus were found, and no abdominal organs were injured.

    The hemihypertrophy or hemihyperplasy is a rare congenital abnormality, characterized by an asymmetric growth of the limbs, the trunk, and the face or half of the entire body. It may be isolated or be part of several syndromes including Beckwith-Wiedemann syndrome, Klippel-Trenaunay-Weber syndrome, Silver-Russell syndrome and Proteus syndrome. In its isolated form, it is called idiopathic. The latter may be associated with several anomalies including dermatological and urogenital abnormalities with increased risk of developing embryonal tumors. We report the case of a 22-month-old infant, who was referred by his pediatrician at the age of 15 months for a corporeal hemihypertrophy associated with hemihypertrichosis. In his medical history, a second degree parental consanguinity and a hypospadias in the father and a paternal uncle were found. Clinical examination found a weight and a size greater than chronological age (3 standard deviations), a hemihypertrophy of entire left side with a difference of length and diameter between the left and right limbs of 2 cm. The hemihypertrichosis was widespread in the left body and the genital examination found a hypospadias. Biological and radiological assessments did not show any abnormality, with the exception of an initially high plasma testosterone level, which gradually normalized. Thus, the diagnosis of idiopathic hemihypertrophy with congenital hemihypertrichosis was retained. This is the fourth case reported in the literature. Its management is similar to all hemihypertrophies, which consists of an initial assessment to detect an embryonic tumor, followed by a monitoring protocol including an abdominal and renal ultrasound every 6 months until the age of 8, determination of alpha-feto-protein every 6 to 12 weeks until the age of 4 years to track the development of the two most frequent tumors: Wilms tumor and hepatoblastoma.

    Full Text Available The objective of the present study was to investigate a possible association between HLA class II antigens and idiopathic focal segmental glomerulosclerosis (FSGS. HLA-A, -B, -DR and -DQ antigens were determined in 19 Brazilian patients (16 white subjects and three subjects of Japanese origin with biopsy-proven FSGS. Comparison of the HLA antigen frequencies between white patients and white local controls showed a significant increase in HLA-DR4 frequency among FSGS patients (37.7 vs 17.2%, P<0.05. In addition, the three patients of Japanese extraction, not included in the statistical analysis, also presented HLA-DR4. In conclusion, our data confirm the association of FSGS with HLA-DR4 previously reported by others, thus providing further evidence for a role of genes of the HLA complex in the susceptibility to this disease

    2017-09-01

    Idiopathic adhesive capsulitis is a common condition resulting in painful multidirectional restriction of motion. Adhesive capsulitis may inhibit shoulder activity level, but this relationship has not been previously studied. This study tested the hypothesis that patients with idiopathic adhesive capsulitis have lower shoulder activity than sex- and age-matched controls. Seventy-two eligible patients (37 men and 35 women) with idiopathic adhesive capsulitis completed a validated shoulder activity scale that was compared with sex- and age-matched norms from a healthy population with no history of shoulder disorders. The association of shoulder activity level with patient age, sex, and American Shoulder and Elbow Surgeons and Simple Shoulder Test (SST) scores was evaluated. Overall, 58% of patients actually had higher shoulder activity scores than sex- and age-matched controls. Among patients aged 51 to 70 years, 68% of patients (73% of men and 63% of women) demonstrated higher Shoulder Activity Scale scores compared with controls. The activity level was higher among all patients aged 51 to 70 years compared with controls (10.3 ± 1.48 vs. 8 ± 0.52, P = .0067). The difference was significant for men in this age group (12.2 ± 1.7 vs. 9 ± 0.75, P = .0042). There was a statistically significant positive correlation of the Shoulder Activity Scale score with the SST score (r = 0.31, P = .009). Patients with idiopathic adhesive capsulitis do not have a lower shoulder activity level than sex- and age-matched controls, and older men may actually have a higher level of shoulder activity than controls. Shoulder activity level is correlated with the SST score in patients with idiopathic adhesive capsulitis. Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees.

    Our objective was to investigate the outcome of neonates with idiopathic polyhydramnios in the first year after birth. All patients diagnosed in the Erasmus Medical Centre Rotterdam and the University Medical Centre Utrecht between January 2000 and April 2005 with idiopathic polyhydramnios were studied. The outcome variables included mode of delivery, pre-term delivery, birth weight, macrosomia, large-for-gestational-age (weight > p90), neonatal or infant mortality and infant morbidity at 1 year after delivery. These were related to antenatal findings, including the onset of polyhydramnios and ultrasonographic evidence of macrosomia (estimated fetal weight > p90). Polyhydramnios was diagnosed at a mean gestational age (+/- s.d.) of 31.0 +/- 4.9 weeks. The mean gestational age at birth (+/- s.d.) was 37.9 +/- 3.7 weeks. Macrosomia at birth was present in 25.3% (22/88). Sixty-three of 88 infants were in good health 1 year after birth; 20 infants had an abnormality and 5 children had died. Macrosomia and detection of polyhydramnios in the third trimester was associated significantly with a good outcome. In neonates with idiopathic polyhydramnios, abnormalities were detected during the first year of life in 28.4%. Detection of polyhydramnios in the second trimester and low or normal birth weight are risk factors for associated abnormalities.

    Idiopathic orbital inflammation (IOI) is defined as a benign non-infective clinical syndrome characterized by features of non-specific inflammation of the orbit without identifiable local or systemic causes. This can be called orbital myositis if the inflammation is predominantly in the orbital muscles. It is a diagnosis of exclusion based on clinical, radiological, and if necessary, histological findings. The most commons symptoms are swelling, ptosis, proptosis and painful eye movements. To our knowledge, this patient is the first with IOI to demonstrate relapsing flitting bilateral involvement of several individual extra-ocular muscles.

    Diffuse idiopathic skeletal hyperostosis has long been regarded as a benign asymptomatic clinical entity with an innocuous clinical course. Neurological complications are rare in diffuse idiopathic skeletal hyperostosis. However, if they do occur, the consequences are often significant enough to warrant major neurosurgical intervention. Neurological complications occur when the pathological process of ossification in diffuse idiopathic skeletal hyperostosis extends to other vertebral ligaments, causing ossification of the posterior longitudinal ligaments and/or ossification of the ligamentum flavum. Thoracic spondylolisthesis with spinal cord compression in diffuse idiopathic skeletal hyperostosis has not previously been reported in the literature. A 78-year-old Japanese man presented with a 6-month history of gait disturbance. A magnetic resonance imaging scan of his cervical and thoracic spine revealed anterior spondylolisthesis and severe cord compression at T3 to T4 and T10 to T11, as well as high signal intensity in a T2-weighted image at T10/11. Computed tomography revealed diffuse idiopathic skeletal hyperostosis at T4 to T10. He underwent partial laminectomy of T10 and posterior fusion of T9 to T12. The postoperative magnetic resonance imaging revealed resolution of the spinal cord compression and an improvement in the high signal intensity on the T2-weighted image. We report the first case of thoracic spondylolisthesis and spinal cord compression in diffuse idiopathic skeletal hyperostosis. Neurosurgical intervention resulted in a significant improvement of our patient's neurological symptoms.

    This paper introduces a model to evaluate the performance of call centers based on the Delone and McLean Information Systems success model. A number of indicators are identified to track the call center’s performance. Mapping of the proposed indicators to the six dimensions of the D&M model is presented. A Weighted Call Center Performance Index is proposed to assess the call center performance; the index is used to analyze the effect of the identified indicators. Policy-Weighted approach was used to assume the weights with an analysis of different weights for each dimension. The analysis of the different weights cases gave priority to the User satisfaction and net Benefits dimension as the two outcomes from the system. For the input dimensions, higher priority was given to the system quality and the service quality dimension. Call centers decision makers can use the tool to tune the different weights in order to reach the objectives set by the organization. Multiple linear regression analysis was used in order to provide a linear formula for the User Satisfaction dimension and the Net Benefits dimension in order to be able to forecast the values for these two dimensions as function of the other dimensions

    SUMMARY - 'Idiopathic' herniation of the brain is a rare entity previously reported in 13 cases. It may be incidentally encountered in neuroimaging studies acquired for various clinical indications. We herein describe two cases of idiopathic brain herniation that were incidentally diagnosed. A 12-year-old boy presented with a six-month history of daytime sleepiness and sudden spells of sleep. Herniation of the left inferior temporal gyrus was revealed in MRI acquired with the suspicion of epilepsy. His overnight polysomnogram and multiple sleep latency tests were compatible with the diagnosis of narcolepsy. The other case, a two-year-old girl, was transferred from an outside hospital due to partial seizures with the fever. Herniation of the precuneal gyrus was encountered in MRI acquired after controlling her seizures with the initiation of phenytoin. The brain herniations of both patients were considered to be inconsistent with their medical conditions, so that they were symptom-free with only medical treatment for following three and six months, respectively. This is a rare presentation of idiopathic brain herniation as an incidental finding that accompanied narcolepsy and epilepsy. Awareness of this entity would avoid excessive surgical and medical treatments.

  18. Clinical efficiency of cyclosporine in chronic idiopathic urticaria in adults

    V.I. Petrov

    2010-06-01

    Full Text Available The purpose of the research is to evaluate the clinical effectiveness of cyclosporine and other antihistamines in patients with chronic forms of urticaria resistant to basic first-line therapy. Open randomized controlled study has been performed in parallel groups. 53 patients with chronic idiopathic urticaria ages 18-50 years have been examined. In case of ineffectiveness of previous therapy, patients have been randomized into 2 groups: group I receiving cyclosporine (Sandimmune Neoral ® 2,5 mg/kg/day, group II receiving cetirizine (Zyrtec ® 10 mg/day and ranitidine (Zantac ® 300 mg/day orally. It has been found that the administration of cyclosporine in patients with severe chronic idiopathic urticaria provides a more rapid achievement of clinical effect than the therapy with H1/H2 histamine antagonists. It is confirmed by a significant decrease of total index of severity of illness and major symptoms of skin lesions. This tendency towards normalization of quality of life of patients taking cyclosporine remains during 8 weeks after the medication. Thus administration of cyclosporine can be considered as therapy of choice in patients with chronic idio-pathic urticaria with a severe course and ineffective long-term therapy with antihistamines / systemic corticosteroids

  5. Relieving idiopathic dental pain without drugs

    Directory of Open Access Journals (Sweden)

    Haryono Utomo

    2011-06-01

    Full Text Available Background: Teeth are commonly obvious source of orofacial pain. Sometimes the pain source is undetectable, thus called as idiopathic dental pain. Since dentist wants to alleviate or eliminate the pains with every effort in their mind, a lot of drugs could be prescribed. Moreover, it is make sense that endodontic treatment or even tooth extraction will be done. Unfortunately, endodontic treatment may also initiate neuropathic tooth pain that is caused by nerve extirpation, thus worsen the pain. Therefore, another cause of dental pain such as referred pain, periodontal disease, or stress which related to psychoneuroimmunology should be considered. In order to prevent from unnecessary drugs or invasive treatment such as root canal treatment and extraction, correct diagnosis and preliminary non-invasive therapies should be done. Purpose: This review elucidates several therapies that could be done by dentists for relieving idiopathic dental pain which includes massage, the “assisted drainage” therapy, modulation of psychoneuroimmunologic status and dietary omega-3. Reviews: Understanding the basic pathogenesis of pain may help in elucidating the effects of non-drug pain therapy such as muscle massage, the “assisted drainage” therapy, omega-3 and psychological stress relieving. These measures are accounted for eliminating referred pain, reducing proinflammatory mediators and relieving unwanted stress reactions consecutively. Psychological stress increases proinflammatory cytokines and thus lowered pain threshold. Conclusion: As an individual treatment, this non-drug therapy is useful in relieving idiopathic dental pain; nevertheless, if they work together the result could be more superior.Latar belakang: Gigi adalah suatu penyebab umum dari nyeri orofasial.

    Cough is a common symptom in idiopathic pulmonary fibrosis that is difficult to treat and has a major impact on quality of life. We tested the hypothesis that the cough and increased cough reflex sensitivity seen in patients with idiopathic pulmonary fibrosis may be due to airway inflammation in a prospective, cross-sectional study. We measured the induced sputum inflammatory cell profile and cell-free supernatant inflammatory mediator concentrations in 15 patients with idiopathic pulmonary fibrosis, 17 healthy controls and 15 patients with chronic obstructive pulmonary disease. Both the geometric mean sputum differential eosinophil cell count and median eosinophilic-cationic-protein concentration were significantly higher in patients with idiopathic pulmonary fibrosis than controls (2.1% vs 0.3%; p <0.001 and 1.1 mg/ml versus 0.2 mg/ml; p=0.03 respectively). There were no significant differences in sputum eosinophil counts and eosinophilic-cationic-protein concentrations between patients with idiopathic pulmonary fibrosis and chronic obstructive pulmonary disease. Sputum leukotriene-B4 concentrations were significantly lower in patients with idiopathic pulmonary fibrosis (p=0.03) and chronic obstructive pulmonary disease (p=0.008) compared to controls. Idiopathic pulmonary fibrosis is characterised by the presence of active eosinophilic airway inflammation raising the possibility that airway inflammation may contribute to symptoms such as cough.

  10. Unexplained childhood anaemia: idiopathic pulmonary hemosiderosis.

    Science.gov (United States)

    Siu, K K; Li, Rever; Lam, S Y

    2015-04-01

    This report demonstrates pulmonary haemorrhage as a differential cause of anaemia. Idiopathic pulmonary hemosiderosis is a rare disease in children; it is classically described as a triad of haemoptysis, pulmonary infiltrates on chest radiograph, and iron-deficiency anaemia. However, anaemia may be the only presenting feature of idiopathic pulmonary hemosiderosis in children due to occult pulmonary haemorrhage. In addition, the serum ferritin is falsely high in idiopathic pulmonary hemosiderosis which increases the diagnostic difficulty. We recommend that pulmonary haemorrhage be suspected in any child presenting with iron-deficiency anaemia and persistent bilateral pulmonary infiltrates.

    2015-07-01

    Full Text Available Idiopathic hypertrophic pyloric stenosis (IHPS is a predominantly infantile disease. The adult type of IHPS is extremely rare but it has been well recognized since the 19th century. We report a case of a 47-year-old male patient who presented with postprandial nausea and vomiting. He underwent upper gastrointestinal endoscopy, and gastric outlet obstruction was discovered. The upper gastrointestinal barium study showed a distended stomach with delayed gastric emptying due to pyloric stenosis. The abdominal computed tomography revealed thickening of the distal stomach. Since gastric malignancy could not be excluded, he underwent antrectomy with Billroth I anastomosis. The pathology revealed no malignancy but showed hypertrophy and hyperplasia of the inner circular muscle of the pylorus, which was compatible with IHPS. We reported the case to remind young physicians of this rare disease.

  12. Pathogenesis of Idiopathic Pulmonary Fibrosis

    Wolters, Paul J.; Collard, Harold R.; Jones, Kirk D.

    2014-01-01

    Idiopathic pulmonary fibrosis (IPF) is a fibrosing interstitial lung disease associated with aging that is characterized by the histopathological pattern of usual interstitial pneumonia. Although an understanding of the pathogenesis of IPF is incomplete, recent advances delineating specific clinical and pathologic features of IPF have led to better definition of the molecular pathways that are pathologically activated in the disease. In this review we highlight several of these advances, with a focus on genetic predisposition to IPF and how genetic changes, which occur primarily in epithelial cells, lead to activation of profibrotic pathways in epithelial cells. We then discuss the pathologic changes within IPF fibroblasts and the extracellular matrix, and we conclude with a summary of how these profibrotic pathways may be interrelated. PMID:24050627

    2018-04-01

    The pathogenesis of idiopathic nephrotic syndrome (INS) is as yet unknown, but several lines of evidence indicate that the immune system may play a crucial pathogenic role in non-genetic INS. The most important of these are, first, the effectiveness of therapy based on immunosuppression and, second, a vast body of data derived both from experimental models and from patient studies that implicate T cells and more recently B cells as major players in INS pathogenesis. However, recent findings also suggest a direct role of podocytes as drivers of the disease process, and the interplay between the glomerulus and the immune system is still being elucidated. In this review we provide an overview of current knowledge on the role of different components of the immune system in determining disease. Advances in our understanding of the pathogenesis of INS may help drive new, more tailored therapeutic approaches.

    Full Text Available Idiopathic inflammatory myopathies (IIM are a heterogeneous group of disease with complex clinical features. It has been sub-classified as: (1 Dermatomyositis, (2 Polymyositis, and (3 Inclusion body myositis (IBM. Nowadays, there are some studies in literature suggest necrotizing autoimmune myopathy and immune-mediated necrotizing myopathy should also be added to this group of disease. There is a debate in the diagnosis of IIMs and up until now, about 12 criteria systems have been proposed. Some of the criteria systems have been used widely such as Griggs et al.'s proposal for IBM. Clinical findings, autoantibodies, enzymes, electrophysiological, and muscle biopsy findings are diagnostic tools. Because of diseases' complexity, none of the findings are diagnostic alone. In this study, we discussed the diagnostic criteria of IMMs and described detailed morphological features. [J Interdiscipl Histopathol 2016; 4(2.000: 41-45

    A mineralogical analysis of lung tissue was conducted on 25 samples from patients who had been diagnosed as having idiopathic pulmonary fibrosis (IPF). Scanning electron microscopy (SEM) at low magnification and energy-dispersive x-ray analysis (EDXA) was used. In all samples, the surface silicon/sulfur (Si/S) ratio was calculated. The Si/S ratio for 25 samples of normal lung and 6 samples of pneumoconiotic lung was also determined (upper limit of normal Si/S ratio = 0.3). The difference between the Si/S ratio in the group with IPF and group with normal lung tissue was significantly significant (p less than .007, Wilcoxon test). Six of 12 patients with a previous diagnosis of IPF and a Si/S ratio greater than 0.3 had an exposure history that could imply inhalation of silica/silicates, and the correct diagnosis for these patients is most probably pneumoconiosis. The silica/silicate deposits detected in patients with IPF, and who had a ratio and no past exposure to dusts, could be either a cause or an effect of the disease

    1999-01-01

    A 40-year-old white man presented with fever, muscle pain, skin nodules and persistent hypereosinophilia over a period of 1 year. In addition, he had ventricular arrhythmias with episodes of tachycardia. Besides a lack of response to antiparasitic therapy, laboratory and pathological data excluded the diagnosis of trichinosis or any other parasitic infection. The patient's course of the disease over the previous 1 1 / 2 years was compatible with hypereosinophilic syndrome. In a muscle biopsy several eosinophilic perivascular and leucocytic intravascular infiltrates were found, indicative of muscle involvement by the disease. This is a report on the MRI findings of muscle involvement in idiopathic hypereosinophilic syndrome. (orig.)

    To investigate the proportion and type of fetal anomalies that are associated with polyhydramnios and to examine whether in cases with idiopathic polyhydramnios during the course of pregnancy and fetal anomalies only diagnosed after birth, antenatal characteristics differ. This was a retrospective study involving all pregnancies with polyhydramnios defined by a deepest pool of amniotic fluid ≥8 cm and a detailed ultrasound examination, a 75 g glucose tolerance test and a TORCH serology. Between 2004 and 2010, 272 pregnancies fulfilled the inclusion criteria. In 89 (32.7%) and 65 (23.9%) cases, there was a fetal anomaly or diabetes. In 118 (43.4%) pregnancies, polyhydramnios was classified as idiopathic. In 11 (9.3%) of the 118 fetuses, an anomaly was found after birth, mainly gastrointestinal atresia. In these cases, median deepest pool of amniotic fluid was 9.6 cm, and median estimated fetal weight was at the 69th centile, whereas in cases without anomalies diagnosed after birth, median deepest pool was 9.0 cm and median estimated fetal weight at the 90th centile (Mann-Whitney U test: deepest pool p = 0.116, and estimated fetal weight centile p = 0.377). There was also no difference in the maternal and gestational age distribution of these cases (Mann-Whitney U test: maternal age p = 0.293, and gestational age p = 0.499). In about 40% of pregnancies, polyhydramnios remains unexplained during the course of pregnancy. In 10% of these cases, an anomaly will only be found after birth. In this group, antenatal characteristics such as amniotic fluid volume, estimated fetal weight or gestational and maternal age at the time of diagnosis do not help to detect these anomalies before birth.

    Previous studies have demonstrated vertebral coplanar alignment (VCA) as an effective surgical option for adolescent idiopathic scoliosis (AIS). The purpose of this study is to analyze the outcome of VCA for the surgical correction of adult idiopathic scoliosis (AdIS). 35 AdIS patients (mean age: 24.2 years) undergoing VCA-instrumentation were reviewed. The main thoracic curve and thoracic kyphosis (TK, T5-T12) were evaluated preoperatively, immediate postoperatively, and at the final follow-up (>1 year). All patients were stratified by the TK modifier before surgery: "+" (TK, >40°), "-" (TK, scoliosis with sagittal malalignment.

  3. Tibial rotational osteotomy for idiopathic torsion. A comparison of the proximal and distal osteotomy levels.

    1992-10-01

    A retrospective analysis was done of 52 rotational tibial osteotomies (RTOs) performed on 35 patients with severe idiopathic tibial torsion. Thirty-nine osteotomies were performed at the proximal or midtibial level. Thirteen were performed at the distal tibial level with a technique previously described by one of the authors. Serious complications occurred in five (13%) of the proximal and in none of the distal RTOs. For severe and persisting idiopathic tibial torsion, the authors recommend correction by RTO at the distal level. Proximal level osteotomy is indicated only when a varus or valgus deformity required concurrent correction.

    Cross-sectional. To describe physical activity level and fracture rates in adults with idiopathic scoliosis, diagnosed before maturity, and to compare with a control group. A previous study found a lower level of sporting activities in adults treated for idiopathic scoliosis compared with controls. Other studies have shown a lower bone mass in adults with idiopathic scoliosis compared with controls. One thousand two hundred seventy-eight adults (aged 18-71 yr) with idiopathic scoliosis and 214 controls (aged 18-70 yr) were included and answered the International Physical Activity Questionnaire - Short Form (IPAQ-SF) and questions about previous fractures. The three scoliosis treatment groups (untreated n = 360, brace n = 460, and surgically treated n = 458) were compared. Furthermore, a comparison based on onset (juvenile n = 169 or adolescent n = 976) was performed. Achieved weekly moderate activity level and metabolic equivalent task (MET) minutes/week were assessed for patients and controls. Statistical comparisons were made with analysis of covariance with adjustments for age, body mass index, and sex. The proportion achieving weekly moderate activity level was 962 out of 1278 for individuals with idiopathic scoliosis (75%) and 157 out of 214 (73%) for controls (P = 0.40). The scoliosis patients reported 2016 MET-minutes/week (median value) and the controls 2456 (P = 0.06). Fracture rates did not differ (P = 0.72). Fewer surgically treated individuals achieved moderate activity level (P = 0.046) compared with the untreated and the previously braced individuals. No difference was seen regarding MET-minutes/week (P = 0.86). No differences were seen between individuals with a juvenile onset compared with individuals with an adolescent onset (all P ≥ 0.05). Adults with idiopathic scoliosis have similar physical activity level and do not sustain more fractures compared with controls. Adults with surgically treated

    Full Text Available Neonatal scrotal hematoma is a rare genitourinary emergency. Some cases have underlining aetiologic factors such as testicular torsion, adrenal hemorrhage, or birth trauma, and others are idiopathic. Previously, immediate scrotal exploration was considered imperative for diagnosis and treatment. With good imaging techniques, some patients are managed nonoperatively. We report a case of idiopathic scrotal hematoma in a neonate. He was managed conservatively with clinical and radiological follow-up. There was complete resolution of hematoma within two months, thus, avoiding unnecessary exploration.

    To evaluate the incidence of non-functioning posterior communicating arteries (PCoA) of the circle of Willis in patients presenting with idiopathic sudden sensorineural hearing loss (SSHL). Pathogenesis of SSHL remains unclear despite several theories. A strong association between non-functioning PCoA of the circle of Willis and SSHL has been recently suggested, supporting the theory of vascular disorders. Tertiary referral center. Ultrasonographic Doppler flow measurements of the vertebrobasilar system were performed prospectively in 27 consecutive patients with idiopathic SSHL and in 27 healthy subjects. A non-functioning PCoA was found in 4 patients with idiopathic SSHL and in 4 cases in the control group. The results of our study did not show any association between non-functioning PCoA of the circle of Willis and idiopathic SSHL, contrasting with previous data. We do not recommend adding routine transcranial Doppler ultrasonography in the test-battery for SSHL.

    2015-07-01

    A 4-year-old male neutered Domestic Medium-hair cat was referred for right head tilt and ataxia of 2 weeks duration. On examination it was determined that the cat had right facial nerve paralysis and peripheral vestibular signs. Haematology and serum biochemical testing were performed in addition to magnetic resonance imaging of the brain and ears, and cerebrospinal fluid analysis. An underlying condition was not identified. A diagnosis of idiopathic vestibular syndrome and concurrent idiopathic right facial nerve paralysis was consequently made. The cat was re-evaluated over the following weeks and was determined to have complete resolution of clinical signs within 7 weeks. Vestibular dysfunction and concurrent facial nerve paralysis have previously been reported in the cat, but not of an idiopathic nature. © 2015 Australian Veterinary Association.

We performed a descriptive study of all patients referred to our regional neurologic clinics from 2010 to 2014 because of facial pain exclusively felt in the eye or in the nose fulfilling the proposed diagnostic criteria for idiopathic ophthalmodynia and idiopathic rhinalgia. There were 9 patients with idiopathic ophthalmodynia and 7 patients with idiopathic rhinalgia, with a clear female preponderance, and a mean age at onset in the fifth decade. The pain was usually moderate and the temporal pattern was generally chronic. Only one patient reported accompaniments (hypersensitivity to the light and to the flow of air in the symptomatic eye). Preventive treatment with amitriptyline, pregabalin, or gabapentin was partially or totally effective. The clinical features of this new series parallels those of the original description, thus indicating that both idiopathic ophthalmodynia and idiopathic rhinalgia have clear-cut clinical pictures with excellent consistency both inter- and intra-individually. © 2015 American Headache Society.

    Gonadotropin-releasing hormone neurons originate outside the central nervous system in the olfactory placode and migrate into the central nervous system, becoming integral components of the hypothalamic-pituitary-gonadal axis. Failure of this migration can lead to idiopathic hypogonadotropic hypogonadism (IHH)/Kallmann syndrome (KS). We have previously shown that CCDC141 knockdown leads to impaired migration of GnRH neurons but not of olfactory receptor neurons. The aim of this study was to further describe the phenotype and prevalence of CCDC141 mutations in IHH/KS. Using autozygosity mapping, candidate gene screening, whole-exome sequencing, and Sanger sequencing, those individuals carrying deleterious CDCD141 variants and their phenotypes were determined in a cohort of 120 IHH/KS families. No interventions were made. Our studies revealed nine affected individuals from four independent families in which IHH/KS is associated with inactivating CCDC141 variants, revealing a prevalence of 3.3%. Affected individuals (with the exception of those from family 1 who concomitantly have FEZF1 mutations) have normal olfactory function and anatomically normal olfactory bulbs. Four affected individuals show evidence of clinical reversibility. In three of the families, there was at least one more potentially deleterious variant in other known puberty genes with evidence of allelic heterogeneity within respective pedigrees. These studies confirm that inactivating CCDC141 variants cause normosmic IHH but not KS. This is consistent with our previous in vitro experiments showing exclusively impaired embryonic migration of GnRH neurons upon CCDC141 knockdown. These studies expand the clinical and genetic spectrum of IHH and also attest to the complexity of phenotype and genotype in IHH. Copyright © 2017 by the Endocrine Society

    Catatonia has been defined as a cluster of signs and occurs secondary to or as a subgroup of schizophrenia, mood disorders or organic syndrome. This study specifically examined the distinct variety of catatonia that did not meet any standard psychiatric diagnostic criteria on globally recognised psychiatric rating tools and compared the clinical features with the catatonia that occurred in association with a diagnosis of schizophrenia. The inpatients in a tertiary psychiatric ward in Ahmedabad, India, between 2002 and 2005 who presented with two or more catatonic signs present for more than 24h period were assessed on Structured Clinical Interview for DSM IV tool. Those with catatonic signs that met diagnostic criteria for schizophrenia (n=21) were compared, with those without any disorder called Idiopathic catatonia (n=13), on measures of Bush Francis Catatonia Rating Scale (BFRCS), Brief Psychiatric Rating Scale (BPRS) and Scale for Assessment of Negative Symptoms (SANS). The scores on duration of illness (U=14.00; pschizophrenia group. The Idiopathic group had significantly higher scores on mean total BFCRS (t=-3.50; df=32; p=0.001) and also on subscores of negativism (p=0.02), waxy flexibility (p=0.02), mitgehen (pcatatonic signs. The study also supports the current concept that there does exists, a distinct variety of catatonia that probably has its own course and prognosis, which need further consideration and more studies to explore this.

    Full Text Available The detection of any atypical extraoral or intraoral features warrants a thorough investigation, even if the patient is asymptomatic or unaware of these. At times, dental findings help in the diagnosis of an underlying systemic problem. These findings may or may not be associated with any syndrome. Thus, thorough examination and exhaustive investigations should be carried out for every atypical finding to ensure optimal oral and general health for the patient. Case Description: This is a case report of seventeen year old male who presented with peculiar/atypical dentition which ′told the tale′ and led to the diagnosis of underlying endocrinological problem about which the parents were totally unaware. The patient was short with central obesity and microcephaly. Intraorally, there was presence of thirty six microdonts. Consultation with pediatrician and endocrinologist, and thorough investigations confirmed the condition to be of ′Idiopathic Hypergonadotropic Hypogonadism′. The patient underwent not only oral rehabilitation, but also timely consultation and treatment from a pediatrician and an endocrinologist.

  20. Autophagy in idiopathic pulmonary fibrosis.

    Directory of Open Access Journals (Sweden)

    Avignat S Patel

    Full Text Available Autophagy is a basic cellular homeostatic process important to cell fate decisions under conditions of stress. Dysregulation of autophagy impacts numerous human diseases including cancer and chronic obstructive lung disease. This study investigates the role of autophagy in idiopathic pulmonary fibrosis.Human lung tissues from patients with IPF were analyzed for autophagy markers and modulating proteins using western blotting, confocal microscopy and transmission electron microscopy. To study the effects of TGF-β(1 on autophagy, human lung fibroblasts were monitored by fluorescence microscopy and western blotting. In vivo experiments were done using the bleomycin-induced fibrosis mouse model.Lung tissues from IPF patients demonstrate evidence of decreased autophagic activity as assessed by LC3, p62 protein expression and immunofluorescence, and numbers of autophagosomes. TGF-β(1 inhibits autophagy in fibroblasts in vitro at least in part via activation of mTORC1; expression of TIGAR is also increased in response to TGF-β(1. In the bleomycin model of pulmonary fibrosis, rapamycin treatment is antifibrotic, and rapamycin also decreases expression of á-smooth muscle actin and fibronectin by fibroblasts in vitro. Inhibition of key regulators of autophagy, LC3 and beclin-1, leads to the opposite effect on fibroblast expression of á-smooth muscle actin and fibronectin.Autophagy is not induced in pulmonary fibrosis despite activation of pathways known to promote autophagy. Impairment of autophagy by TGF-β(1 may represent a mechanism for the promotion of fibrogenesis in IPF.

    Because it is a very rare isolated lesion, we decided to present this case of idiopathic pulmonary artery aneurysm (IPAA) and review the cases published in the literature in order to correlate our clinical and imaging findings, as well as management based on patient data. IPAA was first described in a case of autopsy by Bristowe in 1860 and later in 1947 by Deterling and Claggett, whose prevalence was lower than eight to one hundred thousand. Although the use of diagnostic imaging methods has been applied in a very large population in recent decades, this lesion has been most often described in postmortem examinations. Therefore, it is important to be aware of possible clinical symptoms, at times non-specific, as well as the signs on imaging studies. In this study, therefore, the report of a case of an asymptomatic patient whose diagnosis was done through color Doppler echocardiography in a routine test in 2012, later confirmed by simple chest computed tomography (chest CT) and cardiac catheterization as IPAA and its branches. We discussed the literature available and the possibilities for treatment and the use of color Doppler echocardiography as an initial diagnostic tool for such a rare and intriguing disease. (author)

    2015-11-01

    Idiopathic angioedema is defined as localized swelling of the cutaneous and mucosal tissue that occurs in episodes without a clear etiology. It can be problematic to treat when the underlying pathophysiology is not well understood. To identify successful treatments of idiopathic angioedema reported in the literature. A literature search was performed using PubMed. Published case reports and articles discussing treatment of idiopathic angioedema were used in the formulation of this review. In addition, 2 case reports are provided. Although there are no approved treatments for idiopathic angioedema, several medications used for the treatment of hereditary angioedema, such as bradykinin receptor antagonists (icatibant), kallikrein inhibitors (ecallantide), and C1 inhibitors, were successful in 10 patients. Anti-IgE monoclonal antibody (omalizumab) proved successful in 5 patients. The most widely used and successful medication was tranexamic acid (154 patients). Despite an unknown etiology, this article highlights viable treatment options for idiopathic angioedema. More clinical trials and better markers identifying the cause of angioedema are needed.

    Faecal incontinence is a multifactorial disorder, with multiple treatment options. The role of internal rectal prolapse in the aetiology of faecal incontinence is debated. Recent data has shown the importance of high-grade internal rectal prolapse in case of faecal incontinence. We aimed to determine the incidence and relevance of internal rectal prolapse in patients with faecal incontinence without an anal sphincter defect. Patient data, collected in a prospective pelvic floor database, were assessed. All females with moderate to severe pure faecal incontinence, without obstructed defecation and sphincter muscle defects, were included. Data on defecation proctography, anorectal physiology and incontinence scores were analysed. Of 2082 females in the database, 174 fitted the inclusion criteria. High-grade internal rectal prolapse was found in 49% of patients and was associated predominantly with urge faecal incontinence. Passive faecal incontinence was more common in low-grade compared to high-grade internal rectal prolapse patients. Maximum resting pressure was lower in older patients and in patients with high-grade compared to low-grade internal rectal prolapse. Internal rectal prolapse grade was not significantly correlated with faecal incontinence severity score. High-grade internal rectal prolapse is common in female patients suffering particularly urge faecal incontinence, without anal sphincter lesions. Defecation proctography should be routine in the work up of faecal incontinence. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

    Idiopathic rapid eye movement sleep behaviour disorder is characterized by nocturnal violence, increased muscle tone during rapid eye movement sleep and the lack of any other neurological disease. However, idiopathic rapid eye movement sleep behaviour disorder can precede parkinsonism and dementia by several years. Using 3 T magnetic resonance imaging and neuromelanin-sensitive sequences, we previously found that the signal intensity was reduced in the locus coeruleus/subcoeruleus area of patients with Parkinson's disease and rapid eye movement sleep behaviour disorder. Here, we studied the integrity of the locus coeruleus/subcoeruleus complex with neuromelanin-sensitive imaging in 21 patients with idiopathic rapid eye movement sleep behaviour disorder and compared the results with those from 21 age- and gender-matched healthy volunteers. All subjects underwent a clinical examination, motor, cognitive, autonomous, psychological, olfactory and colour vision tests, and rapid eye movement sleep characterization using video-polysomnography and 3 T magnetic resonance imaging. The patients more frequently had preclinical markers of alpha-synucleinopathies, including constipation, olfactory deficits, orthostatic hypotension, and subtle motor impairment. Using neuromelanin-sensitive imaging, reduced signal intensity was identified in the locus coeruleus/subcoeruleus complex of the patients with idiopathic rapid eye movement sleep behaviour. The mean sensitivity of the visual analyses of the signal performed by neuroradiologists who were blind to the clinical diagnoses was 82.5%, and the specificity was 81% for the identification of idiopathic rapid eye movement sleep behaviour. The results confirm that this complex is affected in idiopathic rapid eye movement sleep behaviour (to the same degree as it is affected in Parkinson's disease). Neuromelanin-sensitive imaging provides an early marker of non-dopaminergic alpha-synucleinopathy that can be detected on an individual

  5. Call cultures in orang-utans?

    Directory of Open Access Journals (Sweden)

    Serge A Wich

    Full Text Available BACKGROUND: Several studies suggested great ape cultures, arguing that human cumulative culture presumably evolved from such a foundation. These focused on conspicuous behaviours, and showed rich geographic variation, which could not be attributed to known ecological or genetic differences. Although geographic variation within call types (accents has previously been reported for orang-utans and other primate species, we examine geographic variation in the presence/absence of discrete call types (dialects. Because orang-utans have been shown to have geographic variation that is not completely explicable by genetic or ecological factors we hypothesized that this will be similar in the call domain and predict that discrete call type variation between populations will be found. METHODOLOGY/PRINCIPAL FINDINGS: We examined long-term behavioural data from five orang-utan populations and collected fecal samples for genetic analyses. We show that there is geographic variation in the presence of discrete types of calls. In exactly the same behavioural context (nest building and infant retrieval, individuals in different wild populations customarily emit either qualitatively different calls or calls in some but not in others. By comparing patterns in call-type and genetic similarity, we suggest that the observed variation is not likely to be explained by genetic or ecological differences. CONCLUSION/SIGNIFICANCE: These results are consistent with the potential presence of 'call cultures' and suggest that wild orang-utans possess the ability to invent arbitrary calls, which spread through social learning. These findings differ substantially from those that have been reported for primates before. First, the results reported here are on dialect and not on accent. Second, this study presents cases of production learning whereas most primate studies on vocal learning were cases of contextual learning. We conclude with speculating on how these findings might

    2015-08-01

    Syncope due to idiopathic AV block is characterized by: 1) ECG documentation (usually by means of prolonged ECG monitoring) of paroxysmal complete AV block with one or multiple consecutive pauses, without P-P cycle lengthening or PR interval prolongation, not triggered by atrial or ventricular premature beats nor by rate variations; 2) long history of recurrent syncope without prodromes; 3) absence of cardiac and ECG abnormalities; 4) absence of progression to persistent forms of AV block; 5) efficacy of cardiac pacing therapy. The patients affected by idiopathic AV block have low baseline adenosine plasma level values and show an increased susceptibility to exogenous adenosine. The APL value of the patients with idiopathic AV block is much lower than patients affected by vasovagal syncope who have high adenosine values. Copyright © 2015 Elsevier Inc. All rights reserved.

  7. Idiopathic eosinophilic gastrointestinal diseases in adults.

    Straumann, Alex

    2008-01-01

    This review focuses on the latest cognitions, diagnosis and treatment strategies of the three main representatives of the eosinophilic gastrointestinal disorders (EGID): idiopathic eosinophilic oesophagitis (EE), idiopathic eosinophilic gastroenteritis (EGE) and idiopathic hypereosinophilic syndromes (HES) with gastrointestinal involvement. These disorders share important similarities: their origin is unknown and their pathogenesis is due to a histological inflammatory response characterised by eosinophilic tissue infiltration. In spite of these parallels, the courses and prognoses of the diseases differ radically: EE is restricted to the oesophagus, and though it may significantly decrease the patient's quality of life, it has a favourable long-term prognosis. In EGE, the inflammatory process involves several segments of the gastrointestinal tract but this chronic inflammation may also be considered a benign disorder. In contrast, HES is primarily a multisystem disorder that may involve several organs, including the digestive tract, and often has a fatal outcome.

    We report a case of a 35 year-old woman with idiopathic thrombocytopenic purpura (ITP) who, under treatment with immunosuppressive drugs, developed bilateral interstitial pulmonary disease. Previously she had been splenectomized and treated with corticosteroids and cyclosporin. During the clinical course, the patient developed alterations of the hepatogram and presented a positive serology for Epstein-Barr virus. The lung biopsy showed the histologic pattern of obliterative bronchiolitis, interstitial inflammatory infiltration and intraalveolar pneumonia (BOOP). We could not find in the literature a previous report in which ITP was associated with BOOP. Of interest was the spontaneous remission of the pulmonary disease after suppression of cyclosporin and positive serology for Epstein-Barr virus.

  9. [Bracing in Adolescent Idiopathic Scoliosis].

    Lo, Yi-Fang; Huang, Yu-Chu

    2017-04-01

    Scoliosis is a common medical problem, with an incidence of between 0.47% and 5.2% in the general population globally. Adolescent idiopathic scoliosis (AIS) accounts for nearly 80% of all scoliosis. Young people with AIS often experience negative social consequences in association with their condition. Without proper and timely treatment, the potential resulting disabilities range from trunk deformity, pain, and neurological complications to compromised cardiopulmonary function, all of which may cause lifelong suffering. Scoliosis may be treated either conservatively or surgically, based on the severity of the disease. Bracing is the most widely adopted method of conservative treatment. However, the main goal of bracing is to inhibit the progression of the spinal curvature rather than to cure scoliosis. The clinical effectiveness of bracing in Taiwan has often been underutilized as a result of financial or other factors such as the availability of the treatment. The purpose of the present review is to clarify the effectiveness of bracing for AIS by elucidating the pathophysiology of scoliosis and examining the recent clinical evidence. The importance of preventative care and the unique contribution of nursing care to treatment has to date been under-recognized. The positive support that nurses provide to the families of the patients during the early phases of treatment as well as to the patients themselves, including helping them exercise appropriately and wear the brace correctly, is an essential component of effective treatment. Learning how to work with and to adapt to the brace being part of the body is an important part of the treatment as well as a way to avoid pain. Nurses are in an ideal position to facilitate this learning process and, overall, to provide health education.

    Idiopathic nephrotic syndrome represents the most common type of primary glomerular disease in children: glucocorticoids (GCs) are the first-line therapy, even if considerable interindividual differences in their efficacy and side effects have been reported. Immunosuppressive and anti-inflammatory effects of these drugs are mainly due to the GC-mediated transcription regulation of pro- and anti-inflammatory genes. This mechanism of action is the result of a complex multistep pathway that involves the glucocorticoid receptor and several other proteins, encoded by polymorphic genes. Aim of this review is to highlight the current knowledge on genetic variants that could affect GC response, particularly focusing on children with idiopathic nephrotic syndrome.

    2017-01-01

    Full Text Available Background. Hypertrophic osteoarthropathy (HOA is a syndrome characterized by abnormal proliferation of the skin and bony structures at the distal extremities resulting in digital clubbing, periosteal bony reaction, and joint effusion. It can be primary (idiopathic without any clear identifiable etiology as well as secondary to variety of systemic diseases most notably lung pathology. Case Presentation. We describe a rare case of primary idiopathic osteoarthropathy in a male patient who presented with severe pain and tenderness in his legs. His history was significant for long standing alcoholism. Physical examination showed severe fingers and toes clubbing. He reported similar changes in his mother. Clinical and radiological findings were remarkable for distal leg tenderness and diffuse periosteal bony reactions, respectively. Computerized tomography scan failed to show any pathology apart from fatty liver infiltration. In the absence of obesity or diabetes, this was consistent with alcoholic steatosis. He was started on nonsteroidal anti-inflammatory drug which dramatically improved his symptoms. Conclusion. Primary hypertrophic osteoarthropathy should be considered in a previously healthy person presenting with bony pain and finger clubbing especially after ruling out the common secondary causes. Moreover, alteration of prostaglandin metabolism secondary to alcoholic consumption might be a contributing factor.

    Full Text Available The aim of our study was to assess the role of rituximab (Mabthera in the treatment of patients with corticosteroid-resistant and calcineurin-inhibitors ± cellcept refractory idiopathic nephrotic syndrome (INS. A total of 83 patients who had required the previous treatment for a minimum of two years were included in the study. Our protocol included the use of rituximab in four-weekly slow infusions. Five patients were excluded as they could not tolerate rituximab infusion for allergic reaction. As expected, none of the patients had a decline in the total circulating lymphocyte counts yet all had achieved decline of their initially normal CD20 to < 0.5% one month after infusion. The decline persisted for eight to ten months later. In the minimal change disease (MCD group, 31 of the 32 patients had complete remission (CR and were off any immunosuppressive therapy and one of the previous non-responders (NR did not respond. Excluding two patients who had required retreatment, the others remained in CR (17 up to 28 months and six up to 36 months. Treatment with rituximab resulted in amelioration of NS in 17 of the 18 patients with focal segmental glomerulosclerosis (FSGS, while only one patient remained NR. Although renal function remained stable, proteinuria reappeared by eight to 12 months. Retreatment with rituximab resulted in a similar response with stable kidney function. In the 28 patients with membranous glomerulopathy (MG, 24 had achieved CR. Two patients failed to respond and two had partial remission. By 12 months, all patients relapsed. The response was within one month following treatment in patient with MCD, but was gradual within three months in FSGS and MG. Relapsers in all groups responded in a similar pattern to repeat dosing with the drug subsequently. Our prospective study represents an adequate number of patients with biopsy-proven subgroups of INS in both children and adults with long-term follow-up of treatment with rituximab

    2008-01-01

    The prevalence of idiopathic normal-pressure hydrocephalus (NPH) in a community was investigated by retrospective analysis of data from a previous community-based study of 170 randomly selected elderly residents aged 65 years or older. Magnetic resonance (MR) images of the subjects were reviewed for the specific structural features of idiopathic NPH, i.e. ventricular enlargement and narrow cerebrospinal fluid (CSF) space at high convexity and high midline areas. The clinical features of idiopathic NPH, gait disturbance, urinary incontinence, and cognitive impairment, were evaluated on the basis of records of the subjects' neurological examinations, a health questionnaire, the Mini-Mental State Examination, and Clinical Dementia Rating. Thirteen of the 170 subjects showed lateral ventricular enlargement greater than 0.3 on Evans' index. Five subjects (2.9%) demonstrated both ventricular enlargement and narrow CSF space at the high convexity/midline. All five subjects with these MR imaging signs had cognitive impairment, one had gait disturbance, and one had urinary incontinence. The present study found 2.9% of community-dwelling elderly subjects showed radiological and clinical features consistent with idiopathic NPH. (author)

  14. Bell's palsy before Bell: Evert Jan Thomassen à Thuessink and idiopathic peripheral facial paralysis.

    2009-11-01

    Bell's palsy is the eponym for idiopathic peripheral facial paralysis. It is named after Sir Charles Bell (1774-1842), who, in the first half of the nineteenth century, discovered the function of the facial nerve and attracted the attention of the medical world to facial paralysis. Our knowledge of this condition before Bell's landmark publications is very limited and is based on just a few documents. In 1804 and 1805, Evert Jan Thomassen à Thuessink (1762-1832) published what appears to be the first known extensive study on idiopathic peripheral facial paralysis. His description of this condition was quite accurate. He located several other early descriptions and concluded from this literature that, previously, the condition had usually been confused with other afflictions (such as 'spasmus cynicus', central facial paralysis and trigeminal neuralgia). According to Thomassen à Thuessink, idiopathic peripheral facial paralysis and trigeminal neuralgia were related, being different expressions of the same condition. Thomassen à Thuessink believed that idiopathic peripheral facial paralysis was caused by 'rheumatism' or exposure to cold. Many aetiological theories have since been proposed. Despite this, the cold hypothesis persists even today.

    2012-01-01

    Full Text Available Lymphoceles are usually related to trauma or surgery, and its spontaneous development is rare. The aim of this paper is to report an uncommon case of idiopathic lymphocele located on the right infraclavicular region, in a female patient with no previous local trauma or surgery and unremarkable medical history. The diagnose was suggested by the tomographic aspect of the lesion and confirmed by ultrasound-guided fluid aspiration and cytological analysis. The authors also provide a brief review of the most important thing diagnostic features and treatment options for this condition. For the practicing clinician, the most important is to achieve an accurate diagnose and to choose the proper therapeutic method according to each clinical scenario.

    Hepatic hematomas in newborn infants are not frequently detected clinically, but are often found at perinatal autopsies. These hematomas of the liver are usually subcapsular in location. A variety of etiologies for such hematomas has been implicated, such as trauma, sepsis, and coagulopathies. We present a neonate who presented with jaundice and abdominal distention. Initial imaging studies revealed a large intraparenchymal lesion of the liver, which was at first thought to be suspicious for neoplasm; however, MRI showed the lesion to be hemorrhagic and follow-up sonographic studies showed total resolution of this lesion, compatible with hematoma. The intraparenchymal location and the idiopathic nature of this lesion distinguish this case from others previously reported. (orig.)

  2. Optimal management of idiopathic scoliosis in adolescence

    Kotwicki, Tomasz; Chowanska, Joanna; Kinel, Edyta; Czaprowski, Dariusz; Tomaszewski, Marek; Janusz, Piotr

    2013-01-01

    Idiopathic scoliosis is a three-dimensional deformity of the growing spine, affecting 2%–3% of adolescents. Although benign in the majority of patients, the natural course of the disease may result in significant disturbance of body morphology, reduced thoracic volume, impaired respiration, increased rates of back pain, and serious esthetic concerns. Risk of deterioration is highest during the pubertal growth spurt and increases the risk of pathologic spinal curvature, increasing angular value, trunk imbalance, and thoracic deformity. Early clinical detection of scoliosis relies on careful examination of trunk shape and is subject to screening programs in some regions. Treatment options are physiotherapy, corrective bracing, or surgery for mild, moderate, or severe scoliosis, respectively, with both the actual degree of deformity and prognosis being taken into account. Physiotherapy used in mild idiopathic scoliosis comprises general training of the trunk musculature and physical capacity, while specific physiotherapeutic techniques aim to address the spinal curvature itself, attempting to achieve self-correction with active trunk movements developed in a three-dimensional space by an instructed adolescent under visual and proprioceptive control. Moderate but progressive idiopathic scoliosis in skeletally immature adolescents can be successfully halted using a corrective brace which has to be worn full time for several months or until skeletal maturity, and is able to prevent more severe deformity and avoid the need for surgical treatment. Surgery is the treatment of choice for severe idiopathic scoliosis which is rapidly progressive, with early onset, late diagnosis, and neglected or failed conservative treatment. The psychologic impact of idiopathic scoliosis, a chronic disease occurring in the psychologically fragile period of adolescence, is important because of its body distorting character and the onerous treatment required, either conservative or surgical

    Nephrotic syndrome is a condition of massive proteinuria that leads to hypoalbuminaemia and oedema. In the pediatric age, the most common form of nephrotic syndrome is childhood idiopathic nephrotic syndrome (CINS). Although the etiological mechanisms underlying CINS are still unclear, the disease is considered to be immune-mediated. Several studies have previously reported a possible association between CINS and atopy, with the latter defined as abnormal immunoglobulin-E response on the background of a T-helper 2 (Th2)-driven immune system. In fact, both experimental and clinical studies have suggested that idiopathic nephrotic syndrome can be associated and/or triggered by a wide array of atopic diseases, though this remains a highly controversial topic. Exposure to inhalant-allergens (and/or introduction of food-allergens) has been previously correlated with the onset and/or the relapse of CINS in some children and a significant worse response to steroid therapy has been also described in reports of CINS associated to concomitant atopic diseases. In this review, we analyzed previous studies with the aim to clarify, basing on the existent literature, the association between atopy and idiopathic nephrotic syndrome. Additionally, we also speculated on the underlying immunological pathways that could potentially make some children prone to both CINS and atopic diseases.

  4. Familial idiopathic gonadotropin deficiency not linked to gene for gonadotropin-releasing hormone (GnRH) in Brazilian kindred

    Familial idiopathic gonadotropin deficiency (FIGD) is an autosomal recessive disorder which results in failure to develop secondary sexual characteristics. The origin is a hypothalamic defect resulting in insufficient secretion of gonadotropin-releasing hormone GnRH (also called LHRH, luteinizing hormone releasing hormone) and follicle-stimuating hormone (FSH). FIGD has been determined to be a separate entity from Kallmann syndrome which presents with hypogonadism as well as anosmia. The FIGD phenotype appears to be analogous to the phenotype of the hpg (hypogonadal) mouse. Because the hpg phenotype is the result of a structurally abnormal GnRH gene, we have studied the GnRH gene in individuals from a previously reported Brazilian FIGD family. An informative dimorphic marker in the signal peptide sequence of the GnRH gene allowed assessment of linkage between the disease gene and the GnRH locus in this pedigree. We have concluded that the GnRH locus is not linked to the disease-causing mutation in these hypogonadal individuals. Recent evidence suggests that neuropeptide Y (NPY) may play a role in the initiation of puberty. We hypothesize that mutations in NPY may result in failure to secrete GnRH. We have characterized three diallelic frequent-cutter restriction fragment length polymorphisms within the human NPY locus, and are currently using these markers to determine if the NPY gene is linked to, and possibly the site of the disease mutation in this kindred.

    Idiopathic laryngotracheal stenosis is an un-common cause of focal airway structure. It develops in adult patients who present clinical signs such as strider and progressive dyspnea. The patients are usually treated for months or years for asthma or chronic bronchial pathology. It most often involves larynx or sub glottal trachea. The histological study establishes the definitive diagnosis, demonstrating the existence of keloid fibrosis with areas of spindle cells. We present the case of an adult man with idiopathic sub glottal stenosis, presenting a two-year history of respiratory distress showing progression in recent months. The study was based on CT findings revealing the existence of a 4 cm long tracheal structure with a minimum diameter of 7 mm. (Author)

  7. Howell-Jolly bodies in idiopathic steatorrhoea.

    1966-03-01

    Large numbers of Howell-Jolly bodies were found in the bone marrow and peripheral blood, both before and after corrective haematinic therapy, in three patients with idiopathic steatorrhoea with associated splenic atrophy, who presented with megaloblastic anaemia. The proportion of erythrocytes containing Howell-Jolly bodies was much higher in these patients when compared with the number found in post-splenectomy subjects. Red cell survival studies of patients' own red cells, sensitized with a potent anti-D serum, showed an abnormally prolonged survival in the three patients with splenic atrophy when compared with those in two splenectomized subjects, in four patients with coeliac disease, and in seven normal controls. There appears to be a relationship between atrophy of the reticuloendothelial system and Howell-Jolly body production in idiopathic steatorrhoea.

    2016-05-01

    Full Text Available With the exception of trauma, intraperitoneal hemorrhage in young women is caused by the high frequency of ectopic pregnancy and ovarian bleeding. Here, we describe a case of idiopathic omental hemorrhage, which is a rare cause of intraperitoneal hemorrhage. Intraperitoneal hemorrhage was suspected in a 38-year-old Japanese woman based on contrast-enhanced computed tomography. Her last menstrual period was 23 days prior, and ovarian bleeding was considered based on bloody ascites revealed by culdocentesis. She underwent emergency surgery for hypovolemic shock. Although both ovaries were of normal size and no abnormal findings were observed, we performed a partial omentectomy because multiple clots were attached only to the greater omentum. Postoperatively, no rebleeding occurred, and she was discharged 11 days after the surgery. Because she did not have a clear history of trauma and underlying disease, idiopathic omental hemorrhage was diagnosed.

    Schwier, Nicholas C; Coons, James C; Rao, Shivdev K

    2015-01-01

    Idiopathic (viral) pericarditis is the most common form of pericardial disease in the Western world. Despite the combination of colchicine and nonsteroidal antiinflammatory drugs (NSAIDs) plus aspirin (ASA), considered first-line therapy, the incidence of recurrent pericarditis is ~20-30%. In addition, secondary recurrence without optimal first-line therapy is ~50%. This is due to the many clinical challenges, such as inappropriate NSAID/ASA duration of therapy, the use of corticosteroid therapy, contraindications or intolerances to therapy, adverse effects, and issues related to adherence. This review describes contemporary pharmacotherapeutic management of idiopathic (viral) pericarditis, with a particular emphasis on the role of colchicine. Emerging therapies and management strategies, such as high-sensitivity C-reactive protein-guided therapy and novel immunotherapies, are also reviewed. Ultimately, understanding appropriate treatment will assist the clinician in helping decrease the risk of recurrent, incessant, and refractory pericarditis. © 2015 Pharmacotherapy Publications, Inc.

Inclusion criteria were papilledema, normal brain computer tomography or magnetic resonance imaging, cerebrospinal fluid pressure greater than 250 mm H2O, normal cerebrospinal fluid content, and a nonfocal neurologic examination except for sixth nerve palsy.Results: Of the nine patients, eight were girls. Five girls were overweight and one boy was obese. The most common presenting symptom was headache (5 patients. Diplopia or strabismus did not occur in our group. Visual field abnormalities were present in all eyes, and severe visual loss resulting in light perception vision occurred in both eyes of one patient. Eight patients were treated medically with acetazolamide alone, and one girl needed a combination of acetazolamide and corticosteroids. This girl also required optic nerve sheath decompression surgery. Resolution of papilledema and recovery of visual function occurred in all patients.Conclusions: Idiopathic intracranial hypertension in prepubertal children is rather uncommon. Prompt diagnosis and management are important to prevent permanent visual loss.Keywords: idiopathic intracranial hypertension, pediatric, treatment

    2012-03-01

    Full Text Available Abstract Idiopathic scoliosis, a common disorder of lateral displacement and rotation of vertebral bodies during periods of rapid somatic growth, has many effects on respiratory function. Scoliosis results in a restrictive lung disease with a multifactorial decrease in lung volumes, displaces the intrathoracic organs, impedes on the movement of ribs and affects the mechanics of the respiratory muscles. Scoliosis decreases the chest wall as well as the lung compliance and results in increased work of breathing at rest, during exercise and sleep. Pulmonary hypertension and respiratory failure may develop in severe disease. In this review the epidemiological and anatomical aspects of idiopathic scoliosis are noted, the pathophysiology and effects of idiopathic scoliosis on respiratory function are described, the pulmonary function testing including lung volumes, respiratory flow rates and airway resistance, chest wall movements, regional ventilation and perfusion, blood gases, response to exercise and sleep studies are presented. Preoperative pulmonary function testing required, as well as the effects of various surgical approaches on respiratory function are also discussed.

    Previous studies have demonstrated an association of osteopenia/osteoporosis with idiopathic benign paroxysmal positional vertigo (BPPV). Since vitamin D takes part in the regulation of calcium and phosphorus found in the body and plays an important role in maintaining proper bone structure, decreased bone mineral density in patients with BPPV may be related to decreased serum vitamin D. We measured the serum levels of 25-hydroxyvitamin D in 100 patients (63 women and 37 men, mean age ± SD = 61.8 ± 11.6) with idiopathic BPPV and compared the data with those of 192 controls (101 women and 91 men, mean age ± SD = 60.3 ± 11.3) who had lived in the same community without dizziness or imbalance during the preceding year. The selection of the controls and acquisition of clinical information were done using the data from the Fourth Korean National Health and Nutrition Examination Survey, 2008. The serum level of 25-hydroxyvitamin D was lower in the patients with BPPV than in the controls (mean ± SD = 14.4 ± 8.4 versus 19.1 ± 6.8 ng/ml, p = 0.001). Furthermore, patients with BPPV showed a higher prevalence of decreased serum vitamin D (diabetes, proteinuria, regular exercise and the existence of decreased bone mineral density demonstrated that vitamin D insufficiency (10-20 ng/ml) and deficiency (<10 ng/ml) were associated with BPPV with the odds ratios of 3.8 (95 % confidence interval = 1.51-9.38, p = 0.004) and 23.0 (95 % confidence interval = 6.88-77.05, p < 0.001). Our study demonstrated an association between idiopathic BPPV and decreased serum vitamin D. Decreased serum vitamin D may be a risk factor of BPPV.

Ophthalmoscopy revealed a horseshoe-like tear on the temporal side of the macula in the left eye. The tear size was 0.75 disc diameters (DD. Optical coherence tomography showed that the focal retinal detachment reached the fovea. A few days after the first visit, there was no longer adhesion of the flap of the tear to the retina and the tear size had increased to 1.5 DD. The patient underwent vitreous surgery similar to large macular hole surgery, with the tear closure repaired using the inverted internal limiting membrane flap technique with 20% SF6 gas tamponade. Although the tear decreased to 0.5 DD after the surgery, complete closure of the tear was not achieved. Conclusion: While cases with horseshoe-like macular tear following trauma and branch retinal vein occlusion have been reported, to the best of our knowledge, this is the first reported idiopathic case. In the present case, there was expansion of the tear until the patient actually underwent surgery. If vertical vitreous traction indeed plays a role in horseshoe-like macular tears, this will need to be taken into consideration at the time of the vitreous surgery in these types of cases. Keywords

    New software to make tetraploid genotype calls from SNP array data was developed, which uses hierarchical clustering and multiple F1 populations to calibrate the relationship between signal intensity and allele dosage. SNP arrays are transforming breeding and genetics research for autotetraploids. To fully utilize these arrays, the relationship between signal intensity and allele dosage must be calibrated for each marker. We developed an improved computational method to automate this process, which is provided as the R package ClusterCall. In the training phase of the algorithm, hierarchical clustering within an F1 population is used to group samples with similar intensity values, and allele dosages are assigned to clusters based on expected segregation ratios. In the prediction phase, multiple F1 populations and the prediction set are clustered together, and the genotype for each cluster is the mode of the training set samples. A concordance metric, defined as the proportion of training set samples equal to the mode, can be used to eliminate unreliable markers and compare different algorithms. Across three potato families genotyped with an 8K SNP array, ClusterCall scored 5729 markers with at least 0.95 concordance (94.6% of its total), compared to 5325 with the software fitTetra (82.5% of its total). The three families were used to predict genotypes for 5218 SNPs in the SolCAP diversity panel, compared with 3521 SNPs in a previous study in which genotypes were called manually. One of the additional markers produced a significant association for vine maturity near a well-known causal locus on chromosome 5. In conclusion, when multiple F1 populations are available, ClusterCall is an efficient method for accurate, autotetraploid genotype calling that enables the use of SNP data for research and plant breeding.

    Isolated left atrial appendage (LAA) ostial stenosis is a very rare entity found coincidentally in adults by transesophageal echocardiography. A 3-month-old healthy infant was suspected as having cor triatriatum. His brother had a history of surgical treatment of cor triatriatum. A cardiac catheterization revealed a narrowed ostium of the LAA and confirmed the echocardiographic diagnosis of isolated LAA ostial stenosis. This is the first pediatric case of idiopathic LAA ostial stenosis. The siblings called our attention to the differential diagnosis and the etiopathogenesis between LAA ostial stenosis and cor triatriatum. © 2016, Wiley Periodicals, Inc.

    To determine the efficacy of transdermal Nitroglycerine patch in idiopathic pre-term labour and foetomaternal outcome. This quasi-experimental study was conducted at the Obstetrics Unit-II of Shaikh Zayed Hospital for Women, Chandka Medical College, Shaheed Mohtarma Benazir Bhutto Medical University, Larkana, from Jan 1 to June 30, 2010. Sixtyfive pregnant women at 28-34 weeks of gestation were recruited after they met the selection criteria based on non-probability consecutive sampling. Initially, 73 patients were selected, but 65 of them completed the treatment, while 8 patients refused to continue. Patients diagnosed with pre-term labour were given glyceryl trinitrate (GTN) 5 mg/12 hours transdermal patch which was applied on the anterior abdominal wall. The second patch of same dose was given after 12 hours. Arrest of labour, prolongation of pregnancy in days or weeks along with side effects of the agent were monitored. Patients were followed till delivery to know the foeto-maternal outcome. Dramatic effects were seen in around 60 (92.3%), of the total patients who had felt relief from premature labour pains within the first hour and only 5 (7.6%) patients could not go beyond 24 hours, as among them 3 (4.61%) had previous uterine scar and 2 (3.07%) developed ruptured membranes after 12 hours of admission and their babies also could not survive. Mean pregnancy prolongation was 15.35 +/- 9.45 days (min: 4 max: 35), so delivery was deferred up to 48 hours, 3 to 7 days and more than 7 days in 4 (6.15%), 6 (9.23%) and 50 (76.92%) respectively. Glyceryl trinitrate, trans dermal patch is effective and safe tocolytic in idiopathic preterm labour. By prolonging pregnancy it improves neonatal outcome.

    Genome-wide association studies (GWAS) are used to discover genes underlying complex, heritable disorders for which less powerful study designs have failed in the past. The number of GWAS has skyrocketed recently with findings reported in top journals and the mainstream media. Microarrays are the genotype calling technology of choice in GWAS as they permit exploration of more than a million single nucleotide polymorphisms (SNPs) simultaneously. The starting point for the statistical analyses used by GWAS to determine association between loci and disease is making genotype calls (AA, AB or BB). However, the raw data, microarray probe intensities, are heavily processed before arriving at these calls. Various sophisticated statistical procedures have been proposed for transforming raw data into genotype calls. We find that variability in microarray output quality across different SNPs, different arrays and different sample batches have substantial influence on the accuracy of genotype calls made by existing algorithms. Failure to account for these sources of variability can adversely affect the quality of findings reported by the GWAS. We developed a method based on an enhanced version of the multi-level model used by CRLMM version 1. Two key differences are that we now account for variability across batches and improve the call-specific assessment of each call. The new model permits the development of quality metrics for SNPs, samples and batches of samples. Using three independent datasets, we demonstrate that the CRLMM version 2 outperforms CRLMM version 1 and the algorithm provided by Affymetrix, Birdseed. The main advantage of the new approach is that it enables the identification of low-quality SNPs, samples and batches. Software implementing of the method described in this article is available as free and open source code in the crlmm R/BioConductor package. Supplementary data are available at Bioinformatics online.

    In a relatively short period, OHS has absorbed multiple call centers supporting different LOBs from various acquisitions, functioning with diverse standards, processes, and technologies. However, customer and employee satisfaction is predicated on OHS's ability to thoroughly integrate these heterogeneous call centers. The integration was initiated and has successfully progressed through a balanced program of focused leadership and a defined strategy which includes site consolidation, sound performance management philosophies, and enabling technology. Benefits have already been achieved with even more substantive ones to occur as the integration continues to evolve.

    Idiopathic membranous nephropathy is a major cause of the nephrotic syndrome in adults, but its etiologic basis is not fully understood. We investigated the genetic basis of biopsy-proven cases of idiopathic membranous nephropathy in a white population. We performed independent genomewide association studies of single-nucleotide polymorphisms (SNPs) in patients with idiopathic membranous nephropathy from three populations of white ancestry (75 French, 146 Dutch, and 335 British patients). The patients were compared with racially matched control subjects; population stratification and quality controls were carried out according to standard criteria. Associations were calculated by means of a chi-square basic allele test; the threshold for significance was adjusted for multiple comparisons (with the Bonferroni method). In a joint analysis of data from the 556 patients studied (398 men), we identified significant alleles at two genomic loci associated with idiopathic membranous nephropathy. Chromosome 2q24 contains the gene encoding M-type phospholipase A(2) receptor (PLA(2)R1) (SNP rs4664308, P=8.6×10(-29)), previously shown to be the target of an autoimmune response. Chromosome 6p21 contains the gene encoding HLA complex class II HLA-DQ alpha chain 1 (HLA-DQA1) (SNP rs2187668, P=8.0×10(-93)). The association with HLA-DQA1 was significant in all three populations (P=1.8×10(-9), P=5.6×10(-27), and P=5.2×10(-36) in the French, Dutch, and British groups, respectively). The odds ratio for idiopathic membranous nephropathy with homozygosity for both risk alleles was 78.5 (95% confidence interval, 34.6 to 178.2). An HLA-DQA1 allele on chromosome 6p21 is most closely associated with idiopathic membranous nephropathy in persons of white ancestry. This allele may facilitate an autoimmune response against targets such as variants of PLA2R1. Our findings suggest a basis for understanding this disease and illuminate how adaptive immunity is regulated by HLA.

    Atsushi Suzuki

    Full Text Available Acute exacerbation (AE is a severe and life-threatening complication of idiopathic pulmonary fibrosis (IPF. In 2016, the definition and diagnostic criteria for AE-IPF were updated by an international working group. The new definition includes any acute, clinically significant respiratory deterioration (both idiopathic and triggered events characterized by evidence of new widespread alveolar abnormality in patients with IPF. There are no currently proven beneficial management strategies for idiopathic and triggered AE-IPF. This is the first report describing AE-IPF triggered by Aspergillus empyema, which was improved by a combination of corticosteroid, systemic antifungal therapy, local antifungal therapy, and additional pharmacological therapies. Future research may reveal optimal strategies for both idiopathic and triggered AE-IPF. Keywords: Idiopathic pulmonary fibrosis, Acute exacerbation, AE-IPF, Triggered AE, Aspergillus infection

  20. Idiopathic toe walking and sensory processing dysfunction.

    Science.gov (United States)

    Williams, Cylie M; Tinley, Paul; Curtin, Michael

    2010-08-16

    It is generally understood that toe walking involves the absence or limitation of heel strike in the contact phase of the gait cycle. Toe walking has been identified as a symptom of disease processes, trauma and/or neurogenic influences. When there is no obvious cause of the gait pattern, a diagnosis of idiopathic toe walking (ITW) is made. Although there has been limited research into the pathophysiology of ITW, there has been an increasing number of contemporary texts and practitioner debates proposing that this gait pattern is linked to a sensory processing dysfunction (SPD). The purpose of this paper is to examine the literature and provide a summary of what is known about the relationship between toe walking and SPD. Forty-nine articles were reviewed, predominantly sourced from peer reviewed journals. Five contemporary texts were also reviewed. The literature styles consisted of author opinion pieces, letters to the editor, clinical trials, case studies, classification studies, poster/conference abstracts and narrative literature reviews. Literature was assessed and graded according to level of evidence. Only one small prospective, descriptive study without control has been conducted in relation to idiopathic toe walking and sensory processing. A cross-sectional study into the prevalence of idiopathic toe walking proposed sensory processing as being a reason for the difference. A proposed link between ITW and sensory processing was found within four contemporary texts and one conference abstract. Based on the limited conclusive evidence available, the relationship between ITW and sensory processing has not been confirmed. Given the limited number and types of studies together with the growing body of anecdotal evidence it is proposed that further investigation of this relationship would be advantageous.

    Objective To estimate the association between the severity of idiopathic polyhydramnios and adverse outcomes. Study Design Retrospective cohort study of deliveries at one hospital from 2000 to 2012 with an amniotic fluid index (AFI) measurement ≥24 + 0 weeks' gestation. Pregnancies complicated by diabetes, multiples, or fetal anomalies were excluded. Exposure was the degree of polyhydramnios: normal (AFI 5-24 cm), mild (≥ 24-30 cm), and moderate-severe (> 30 cm). Primary outcomes were perinatal mortality, neonatal intensive care unit (NICU) admission, and postpartum hemorrhage. Results There were 10,536 pregnancies: 10,188 with a normal AFI, 274 mild (78.74%), and 74 moderate-severe polyhydramnios (21.26%). Adverse outcomes were increased with idiopathic polyhydramnios: NICU admission (adjusted odds ratio [AOR] 3.71, 95% confidence interval [CI] 2.77-4.99), postpartum hemorrhage (AOR 15.81, 95% CI 7.82-31.96), macrosomia (AOR 3.41, 95% CI 2.61-4.47), low 5-minute Apgar score (AOR 2.60, 95% CI 1.57-4.30), and cesarean (AOR 2.16, 95% CI 1.74-2.69). There were increasing odds of macrosomia (mild: AOR 3.19, 95% CI 2.36-4.32; moderate-severe: AOR 4.44, 95% CI 2.53-7.79) and low 5-minute Apgar score (mild: AOR 2.24, 95% CI 1.23-4.08; moderate-severe: AOR 3.93, 95% CI 1.62-9.55) with increasing severity of polyhydramnios. Conclusion Idiopathic polyhydramnios is independently associated with increased risks of morbidity. There appears to be a dose-response relationship for neonatal macrosomia and low 5-minute Apgar score risks. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Seven cases of idiopathic Horner's Syndrome in the Collie are described. Five males and two females presented with unilateral miosis, ptosis of the upper eyelid, enophthalmos and protrusion of the third eyelid. Thorough examination, pharmacological testing with phenylephrine, complete blood counts and radiography of the tympanic bullae and thorax were performed. The etiology was not identified in any of the cases. Clinical signs improved with pharmacologic testing within 20-40 min. In five dogs, total resolution of clinical signs was observed at 4 and 16 weeks after their initial appearance. Pharmacological testing suggested that the deficit could be at the preganglionic neuron

    Full Text Available A 50-year-old Taiwanese woman had a history of massive hemoptysis occurring every 6 months for the past 4 years. After each bout of hemoptysis, chest roentgenography would show diffuse alveolar infiltration of bilateral lungs, which would usually resolve within 7 days. Transbronchial biopsy revealed diffuse alveolar hemorrhage and hemosiderin-laden macrophage infiltration. Idiopathic pulmonary hemosiderosis was diagnosed by excluding other glomerular, cardiac and immunological disorders. An initial dose of 20 mg prednisolone daily was tapered to 10 mg daily 1 month later. The patient is currently undergoing steroid therapy, and there have been no further episodes of hemoptysis.

    Renal vein thrombosis (TVR) is not a common disease especially when is not associated with renal parenchymal nephropathy. TVR has no characteristic symptoms, so it is often late recognised. The main procedures for diagnosis of TVR are: echotomography, CT and phlebography. All these procedures, although very informative, have certain limits in the clinical use. Therapy of TVR trombolytic, anticoagulant or surgical: thrombectomy or nephrectomy. In cases where the underlying parenchymal disease exists, aggresive therapeutic approach is not recommended, but in acute idiopathic TVR immediate recanalisation of the renal vein is the most effective.

    The terms 'persistent idiopathic facial pain' (PIFP) and 'atypical odontalgia' (AO) are currently used as exclusion diagnoses for chronic toothache and chronic facial pain. Knowledge about these pain conditions in medical and dental practices is of crucial importance for the prevention of iatrogenic tissue damage by not-indicated invasive interventions, such as endodontic treatment and tooth extraction. In the present paper, etiology and pathogenesis, differential diagnostic criteria, and diagnostic approaches will be explained and relevant therapeutic principles will be outlined. Copyright © 2013.

    Objective: Absence seizures in patients with idiopathic generalized epilepsy (IGE) may in part be explained by a decrease in phasic GABAA (type-A c-aminobutyric acid) receptor function, but the mechanisms are only partly understood. Here we studied the relation between ictal and interictal spike...... decrease in the 8-12 Hz frequency band. The rise in EEG gamma oscillations was short-lasting and decreased before activity declined at lower frequency ranges. Compared to control patients, patients with epilepsy also showed higher interictal values of mean coherence of gamma activity, but this interictal...

    To report a case of an idiopathic unilateral filtering bleb in an otherwise well patient and a case of bilateral spontaneous filtering blebs in association with Terrien marginal degeneration. In this retrospective observational study of 2 cases, clinical notes, ultrasound biomicroscopy and gonioscopy images were reviewed. Case 1: A 32-year-old woman presented with a 1-year history of a gradually growing cyst in her right eye. No changes in vision were reported. The patient had no previous ocular or systemic history, trauma, or surgical interventions. Slit-lamp examination revealed a multilobulated cyst at the supranasal limbus OD. Diagnosis was an idiopathic spontaneous limbal filtering bleb of unclear etiology because there was no inciting event or obvious cause. Case 2: A 31-year-old man, with 2 past episodes of spontaneous filtering bleb development, affecting the left, then the right, eye, presented with his third event in May 2012. The visual acuity was decreased to 20/400 OD. The right eye was hypotonous and ultrasound biomicroscopy confirmed a shallow anterior chamber, a superior peripheral corneal defect, and an echolucent space suggestive of subconjunctival fluid. Limbal thinning was noted bilaterally, consistent with Terrien marginal degeneration. This is a rare case of an idiopathic filtering bleb occurring in a healthy patient with no precipitating cause, other ocular abnormalities, or physical malformations, and the only reported case of bilateral sequential filtering blebs associated with an atypical presentation of Terrien marginal degeneration.

  15. Weakness of the neck extensors, possible causes and relation to adolescent idiopathic cervical kyphosis.

    Cervical kyphosis may be congenital, or occur as a result of laminectomy, post-traumatic deformity, infection, neuromuscular disorders such as muscular dystrophies, motor neuron disorders such as amyotrophic lateral sclerosis, tumor, and inflammation such as ankylosing spondylitis. Furthermore, adolescent idiopathic cervical kyphosis was defined as cervical kyphotic deformity of adolescent patient without any cause such as those previously described. As no standard values for "cervical kyphosis" could be found in the literature, many reported studies only report a subjective classification, "kyphotic, straight or lordotic". But this method had proven to be unreliable. Grob et al. defined "straight" for the global curvature as +4° to -4°, and lordotic and kyphotic as +4°, respectively. The etiology and pathogenesis of adolescent idiopathic cervical kyphosis remain little understood. Weakness of the neck extensors can result in "dropped head syndrome", a rare disorder characterized by weakness of neck extensor muscles causing an inability to extend the neck and resulting in a chin-on-chest deformity. The purpose of this paper is to propose a possible mechanical cause leading to the kyphotic deformity. We hypothesize that weakness of the neck extensors could be the initiating factor for adolescent idiopathic cervical kyphosis. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Introduction: The possibility of developing idiopathic portal hypertension has been described with thiopurine treatment despite compromises the prognosis of these patients, the fact its true prevalence is unknown. Material and methods: A cross-sectional study was conducted in a cohort of inflammatory bowel disease (IBD patients followed at our unit, to determine the prevalence of diagnosis of idiopathic portal hypertension (IPH and its relationship with thiopurine treatment. Results: At the time of the analysis, 927/1,419 patients were under treatment with thiopurine drugs (65%. A total of 4 patients with IBD type Crohn's disease with idiopathic portal hypertension probably related to the thiopurine treatment were identified (incidence of 4.3 cases per 1,000. Seventy-five percent of patients started with signs or symptoms of portal hypertension. Only one patient was asymptomatic but the diagnosis of IPH because of isolated thrombocytopenia is suspected. However, note that all patients had thrombocytopenia previously. Abdominal ultrasound with fibroscan, hepatic vein catheterization and liver biopsy were performed on all of them as part of the etiology of portal hypertension. In the abdominal ultrasound, indirect portal hypertension data were observed in all patients (as splenomegaly cirrhosis was also ruled out. The fibroscan data showed significant liver fibrosis (F2-F3. Conclusion: Idiopathic portal hypertension following thiopurine treatment in IBD patients is a rare occurrence, but it must be borne in mind in the differential diagnosis for early diagnosis, especially in patients undergoing thiopurine treatment over a long period. The presence of thrombocytopenia is often the only predictor of its development in the preclinical stage.

    Full Text Available Objectives: Anastomotic patency with return of sperm in the ejaculate following microsurgical vasoepididymostomy (VEA is not universal and may be delayed. The ability to predict the result of VEA based on preoperative or intra-operative parameters would enable the surgeon to offer the best treatment to the infertile couple. We used the two-stitch invagination technique of VEA in patients of idiopathic obstructive azoospermia and prospectively analyzed factors that could predict a patent anastomosis. While such studies have previously been done for patients undergoing VEA for secondary infertility following a vasectomy, to the best of our knowledge this is the first study analyzing these parameters for patients with primary infertility and idiopathic obstruction. Methods and materials: Over a 2-year period, 29 men underwent the 2-suture invagination VEA for idiopathic obstructive azoospermia. Twenty-four patients provided at least one postoperative semen sample. Preoperative and intra-operative parameters were compared between patients with a patent anastomosis with sperm in ejaculate (n = 12 and those with no sperm in the ejaculate (n = 12 using the t-test, Fisher′s exact test or chi-square test, as appropriate and a multivariate statistical analysis to determine any significant difference. Results: The mean follow up of the 24 patients was 7.6 months (2-30 months. A significantly greater number of patients with patent anastomosis had motile epididymal sperms (P = 0.034 and higher surgeon′s technical satisfaction with the procedure (P = 0.034. However, this difference was seen only on a univariate analysis and did not persist when a multivariate analysis was used. Conclusions: The presence of motile sperms in the epididymal fluid and a high level of technical satisfaction with the anastomosis may indicate a higher likelihood of success following a vaso-epididymal anastomosis for idiopathic obstruction. However, these parameters are not

    Full Text Available The vocal repertoire of some animal species has been considered a non-invasive tool to predict distress reactivity. In rats ultrasound emissions were reported as distress indicator. Capybaras[ vocal repertoire was reported recently and seems to have ultrasound calls, but this has not yet been confirmed. Thus, in order to check if a poor state of welfare was linked to ultrasound calls in the capybara vocal repertoire, the aim of this study was to track the presence of ultrasound emissions in 11 animals under three conditions: 1 unrestrained; 2 intermediately restrained, and 3 highly restrained. The ultrasound track identified frequencies in the range of 31.8±3.5 kHz in adults and 33.2±8.5 kHz in juveniles. These ultrasound frequencies occurred only when animals were highly restrained, physically restrained or injured during handling. We concluded that these calls with ultrasound components are related to pain and restraint because they did not occur when animals were free of restraint. Thus we suggest that this vocalization may be used as an additional tool to assess capybaras[ welfare.

    2014-10-01

    Chronic idiopathic angioedema (CIA) is defined as three or more episodes of angioedema in a period of > 6 months without a clear etiology. In the study, we tried to explore clinical and laboratory characteristics of patients with CIA unaccompanied by urticaria. We retrospectively reviewed clinical and laboratory characteristics of 1238 patients with chronic urticaria and/or angioedema referred to our allergy clinic. Eight hundred and forty-one (67.9%) subjects had chronic urticaria without angioedema (CU Group), 323 (26.1%) had both urticaria and angioedema (CU + CA group), and 74 (5.9%) had chronic angioedema without urticaria (CA). In 29 (39.2%) cases of CA, no etiologic factor of angioedema was discovered, thus the patients were defined as having chronic idiopathic angioedema (CIA Group). Twenty-two (75.8%) subjects had antihistamine-responsive CIA and seven (24.1%) had antihistamine-unresponsive CIA. There were no statistically significant differences in clinical (except of urticarial eruptions) and laboratory characteristics between CU, CA + CU, and CIA groups. Antihistamine responsive and antihistamine-unresponsive CIA groups had no distinguishable clinical or laboratory features. We suppose that CIA, at least its antihistamine-responsive form, represents a rare form of chronic spontaneous urticaria. The reasons why in CIA there are no other clinical signs of mast cell/basophil activation, such as pruritus, urticarial, and dermatographism, are largely unknown and have to be elucidated in future studies. © 2014 The International Society of Dermatology.

    Full Text Available Introduction. Harlequin syndrome is a very rare neurological condition characterized by redness and excessive sweating of one half of the face in response to exercise and emotions. In most cases this disorder is not life-threatening. Objective. To present diagnostic difficulties of Harlequin syndrome in dermatological practice. Case report. We present a case of a 30-year-old man with redness and excessive sweating of the right half of the face as a result of exercise that was observed during the diagnosis of chronic urticaria at the Department of Dermatology. The patient was examined ophthalmologically and neurologically, had a CT scan of the head, and the Minor test performed. Idiopathic Harlequin syndrome was diagnosed based on case history and workup results. Conclusions . Harlequin syndrome occurs most often in the form of an idiopathic condition, but neurologic and ophthalmologic assessment should be performed since some diseases, such as brainstem infarction and schwannoma of the upper chest, may initially appear as Harlequin syndrome.

    Previous work has noted that some children with autism spectrum disorder (ASD) display weaknesses in receptive vocabulary relative to expressive vocabulary abilities. The current study extended previous work by examining the receptive-expressive vocabulary profile in boys with idiopathic ASD and boys with concomitant ASD and fragile X syndrome (ASD + FXS). On average, boys with ASD + FXS did not display the same atypical receptive-expressive profile as boys with idiopathic ASD. Notably, there was variation in vocabulary abilities and profiles in both groups. Although we did not identify predictors of receptive-expressive differences, we demonstrated that nonverbal IQ and expressive vocabulary positively predicted concurrent receptive vocabulary knowledge and receptive vocabulary predicted expressive vocabulary. We discuss areas of overlap and divergence in subgroups of ASD. PMID:27796729

    Full Text Available Macrophage activation syndrome, a severe complication of systemic juvenile idiopathic arthritis and other inflammatory diseases, represents one of the most important rheumatological emergencies. Delayed diagnosis could lead to life-threatening complications. Pulmonary hemosiderosis has been classically characterized by a triad of anemia, hemoptysis, and lung infiltrates on chest radiogram. Although the majority of patients of pulmonary hemosiderosis are considered idiopathic, secondary hemosiderosis associated with known diseases could be seen. In this case report, we aimed to present gradually increased pulmonary manifestations due to pulmonary hemosiderosis with recurrent macrophage activation syndrome attacks in a child with systemic juvenile idiopathic arthritis.

    Full Text Available Diffuse idiopathic skeletal hyperostosis (DISH is usually asymptomatic. However, rarely, it causes dysphagia, hoarseness, dyspnea, snoring, stridor, and laryngeal edema. Herein, we present a patient with DISH causing dysphagia. A 70-year-old man presented with a 4-month history of sore throat, dysphagia, and foreign body sensation. Flexible laryngoscopy revealed a leftward-protruding posterior wall in the hypopharynx. Computed tomography and magnetic resonance imaging revealed a bony mass pushing, anteriorly, on the posterior hypopharyngeal wall. Ossification included an osseous bridge involving 5 contiguous vertebral bodies. Dysphagia due to DISH was diagnosed. His symptoms were relieved by conservative therapy using anti-inflammatory drugs. However, if conservative therapy fails and symptoms are severe, surgical treatments must be considered.

    The rapid growth of the spine during the pubertal spurt requires greater vigilance for the pediatrician at the annual check during this period to detect the occurrence of scoliosis. Before confirming the diagnosis of idiopathic scoliosis, it is imperative to exclude a secondary cause with appropriate history and clinical examination, and in selective cases with additional testing. Any scoliosis detected during growth should be considered potentially progressive and sent to a specialist if it is equal to or exceeds 20° on the X-rays. Radiological changes of more than 5° during a 6 months interval must also motivate an appointment with a specialist. Regular clinical and radiological surveillance, every 6 months, remains imperative to confirm or deny this risk of progression and decide on treatment.

    Full Text Available Diffuse idiopathic skeletal hyperosteosis (DISH is also known as Forestier disease and is a systemic non-inflammatory disorder seen more commonly in males and elderly. It is characterized by calcification of the anterior longitudinal ligament of the vertebral column and various extraspinal ligaments. It is usually asymptomatic while the most common symptoms are spinal pain, limited range of spinal motion and dysphagia due to esophagus compression. The etiopathogenesis is not clear. It is commonly seen together with diabetes mellitus, obesity, hyperinsulinemia, hypertension and lipid and purine metabolism disorders, indicating an association with metabolic disorders. Recent studies have emphasized that the pathological calcification of the anterior longitudinal ligament plays a role in the pathophysiology. The aim of this study was to summarize new pathogenetic, clinical and therapeutic insights of this disease, based on published literature.

    Idiopathic interstitial pneumonias are at present classified as one of four types: usual, nonspecific, acute, or desquamative. The acute form has the worst prognosis, followed by the usual and the nonspecific form; it is in desquamative cases that prognosis is best. At high-resolution CT, usual interstitial pneumonia, the most frequent type, manifests as patchy subpleural areas of ground-glass attenuation, irregular linear opacity, and honeycombing, which the nonspecific type, the second most frequent, appears as subpleural patchy areas of ground-glass attenuation with associated areas of irregular linear opacity. Acute interstitial pneumonia demonstrates extensive bilateral airspace consolidation and patchy or diffuse bilateral areas of ground-glass attenuation in middle and lower lung zones

    Full Text Available Malignant hyperthermia (MH is a rare but life-threatening condition that is more frequently encountered and discussed within the anesthesia literature. Here we through a case specifically discuss the susceptibility of individuals and/or families with asymptomatic unexplained elevations of creatine kinase (CK, also frequently referred to as hyperCKemia or idiopathic hyperCKemia (IHCK in recent reports. The clinical implications would be to underscore the importance of this as a susceptibility to developing MH and highlight the importance of genetic susceptibility testing in such cases. Anesthesiologists and critical care intensivists as well as primary care physicians should keep this in mind when seeing patients with asymptomatic hyperCKemia and potentially inform them about the possibility of developing MH if exposed to triggering agents. Genetic susceptibility testing should be considered if available and family members should also receive nontriggering agents when undergoing anesthesia and wear Medic Alert tags.

    Idiopathic pulmonary hemosiderosis is a rare disorder that can occur at any age and is characterized by the triad of hemoptysis, iron deficiency anemia and diffuse pulmonary infiltrates. The clinical course is exceedingly variable especially in children and a substantial proportion of this age group is undiagnosed. It is probably due to the fact that iron deficiency anemia may be the first and the only manifestation of IPH, preceding other symptoms and signs by several months and IPH is not considered as a rare cause of anemia, unless the typical triad is present. We present a case of IPH in a 13-year-old girl, treated for several months with persistent iron deficiency anemia, without response to therapy.

    Single-voxel proton magnetic resonance spectroscopy ({sup 1}H-MRS), localised to the basal ganglia, was used to determine changes in metabolite levels in idiopathic spasmodic torticollis (IST). We examined nine patients and 13 healthy subjects. The mean values ({+-} SD) of peak area ratios were: IST: N-acetyl-aspartate (NAA)/choline-containing compounds (Cho) 1.79 {+-} 0.39, NAA/creatine and phosphocreatine compounds (Cr) 1.61 {+-} 0.38, Cho/Cr 0.91 {+-} 0.19; controls: NAA/Cho 2.07 {+-} 0.35, NAA/Cr 1.82 {+-} 0.31, Cho/Cr 0.89 {+-} 0.12. Statistical analysis showed that NAA/Cho and NAA/Cr were significantly lower in patients than in controls (P = 0.0304 and 0.0431, respectively). These results indicate a reduction in NAA, and suggest striatal involvement in the pathogenesis IST. (orig.)

    Idiopathic pulmonary fibrosis (IPF) is a progressive and ultimately fatal interstitial lung disease. After many drugs failed in clinical trials, improvements in the understanding of the pathogenesis of IPF led to the approval of two drugs that slow the progression of the disease. However, the prognosis for patients with IPF remains poor and the search continues for drugs that inhibit the pathogenic pathways active in IPF to reduce or even halt the progression of the disease. In this article, we review the mechanisms of action of the two approved therapies for IPF (nintedanib and pirfenidone) and of the investigational compounds that are in Phase II trials and discuss the potential for combination therapy in the treatment of IPF.

    Two patients presented with ureteric obstruction, and voiding symptoms and constipation, respectively, and were examined by means of intravenous urography and computed tomography. One patient was additionally examined by means of MR tomography. After CT (performed in both patients) and MRT (performed in one patient) had shown a diffuse, contrast-enhancing, infiltrating process in the small pelvis with infiltration of adjacent organs and vessels, surgical biopsy proved the diagnosis of idopathic pelvic fibrosis. Extension of retroperitoneal fibrosis below the pelvic rim is very rare. Clinical symptoms of pelvic fibrosis are variable and imaging findings may lead to a broad list of differential diagnoses. We present two patients with idiopathic pelvic fibrosis and discuss radiological findings and differential diagnoses of this rare disease. (orig.)

    Templeton, Christopher N.; Greene, Erick

    2007-01-01

    Many animals recognize the alarm calls produced by other species, but the amount of information they glean from these eavesdropped signals is unknown. We previously showed that black-capped chickadees (Poecile atricapillus) have a sophisticated alarm call system in which they encode complex information about the size and risk of potential predators in variations of a single type of mobbing alarm call. Here we show experimentally that red-breasted nuthatches (Sitta canadensis) respond appropriately to subtle variations of these heterospecific “chick-a-dee” alarm calls, thereby evidencing that they have gained important information about potential predators in their environment. This study demonstrates a previously unsuspected level of discrimination in intertaxon eavesdropping. PMID:17372225

    2012-01-01

    The objective of this study was to determine whether contact allergens play a role in chronic idiopathic urticaria (CIU). We conducted a longitudinal prospective study of 23 patients with CIU. Patients were patch tested to a modified North American Contact Dermatitis Group standard, fragrance, and cosmetic series; other series were tested as warranted by relevant history and physical examination. Readings were performed at 48 and 72 hours. Patients were counseled to avoid proven contact allergens and were followed up 2 to 9 months after testing. Twenty-one of 23 patients were female. The mean age was 46 years. The mean duration of urticaria was 32 months. Of the 23 patients, 8 (35%) experienced improvement of their symptoms with allergen avoidance. Four (17%) experienced a complete remission, and 4 (17%) experienced partial improvement. Two of the complete responders challenged themselves to proven contact allergens and developed urticaria, which resolved upon allergen avoidance. The most common allergens were potassium dichromate (n = 9), nickel sulfate (n = 7), Myroxylon pereirae (n = 6), cobalt chloride, neomycin, p-phenylenediamine (n = 5); fragrance mix I, fragrance mix II (n = 4); cinnamic aldehyde (n = 3); and formaldehyde (n = 2). Patch testing may be helpful in the evaluation of CIU patients for whom previous workup has failed to reveal an etiology.

    2011-01-01

    Idiopathic pulmonary hemosiderosis (IPH) is a rare disorder (triad of iron-deficiency anemia, hemoptysis, and alveolar infiltrates). A 3-year-old male presented with mild fever, breathlessness, dry cough, and bluish nail discoloration for 8 days. He had required five blood transfusions in the past 1 year (last transfusion was given 4 months ago). He had a respiratory rate of 58/min with respiratory distress, cyanosis, and grade III clubbing. Respiratory system examination was normal. Several previous reports of hemoglobin were as low as 3.6 g/dl with hypochromic and microcytic anemia. There were transient increases in the hemoglobin and normalization of red cell morphology with blood transfusions. Serum iron, G6PD enzyme assay, hemoglobin electrophoresis, the sickling test, Coomb's test, stool and urine analysis, and a Meckel's scan were normal. HIV antibody and dsDNA were negative. The chest radiograph revealed symmetrical patchy infiltrates sparing lung apices (confirmed on high-resolution computed tomography). Lung biopsy diagnosed pulmonary hemosiderosis (interstitial lung disease with hemosiderin-laden macrophages scattered in the alveoli and areas of fibrosis in the alveolar septa). The patient showed marked clinical improvement in 10 days of therapy with prednisolone. IPH should be listed in the differential diagnosis of a child presenting with unexplained hypochromic, microcytic anemia and respiratory symptoms.

    Diffuse alveolar hemorrhage (DAH) of unknown cause has been characterized as idiopathic pulmonary hemosiderosis (IPH). IPH is a rare disease, which has a high prevalence in children and shows a poor prognosis. However, in adults, since there are few reports about collective cases, the details remain to be determined. Between January 2003 and June 2008, consecutive adult patients strictly defined as unknown cause DAH by chest images, fiberoptic bronchoscopy, autoantibody testing, and exclusion of systemic disease were enrolled. We investigated the clinical characterization and course of the enrolled patients. Nine patients were included. All patients were middle-aged men (56.1 ± 4.2 year-old) with sudden onset. They did not present with anemia (the hemoglobin level was 13.9 ± 0.5 g/dL) despite the quantity of bleeding. In bronchoalveolar-lavage fluid analysis, the cell count was increased (7.6 ± 1.6×10(5) cells/mL) with neutorophilia (33.3 ± 13.3%). The illness resolved within 2 weeks with or without corticosteroid therapy. All of the patients were alive without recurrence during the follow-up period (45.2 ± 6.2 months) after diagnosis. Adult IPH patients showed good prognosis. However, the present patients are clinically slightly different from the previously characterized IPH.

  1. Repository Corticotropin Injection for Treatment of Idiopathic Inflammatory Myopathies

    Full Text Available Idiopathic inflammatory myopathies are a group of systemic autoimmune diseases that involve inflammation of skeletal muscle. The two most common forms are dermatomyositis and polymyositis, the former of which entails a skin component. There are few approved therapeutics available for treatment of this group of diseases and the first-line therapy is usually corticosteroid treatment. Considering that a large proportion of patients do not respond to or cannot tolerate corticosteroids, additional treatments are required. There are second-line therapies available, but many patients are also refractory to those options. H.P. Acthar® Gel (repository corticotropin injection [RCI] is a melanocortin peptide that can induce steroid-dependent effects and steroid-independent effects. Herein, we present a series of cases that involved the use of RCI in the management of dermatomyositis and polymyositis. RCI treatments resulted in improvement in three of four patients, despite failure with previous therapies. The use of RCI did not exacerbate any comorbidity and no significant changes in blood pressure, weight, or glycemic control were observed. Overall, these results are encouraging and suggest that randomized, controlled clinical trials applying RCI to dermatomyositis and polymyositis are warranted.

    Patients suffering from Idiopathic Environmental Intolerances (IEI) report health symptoms, referable to multiple organ systems, which are triggered by harmless odors and therefore medically unexplainable. In line with previous research that predominantly points towards psychological explanations, the present study tests the hypothesis that IEI symptoms result from learning via classical conditioning of odors to fear. A differential conditioning paradigm was employed. Hedonically different odors were compared on ease of fear acquisition. Conditioned stimuli (CSs) were Dimethyl Sulfide (unpleasant) and peach (pleasant). The unconditioned stimulus (US) was an electrical shock. During acquisition one odor (CS+) was followed by shock, while the other odor (CS-) was not. Next, fear extinction was tested by presenting both CS+ and CS- without US. Electrodermal response, odor evaluation, and sniffing behavior were monitored. Results showed successful fear conditioning irrespective of hedonic character as evidenced by electrodermal response. Acquired fear did not extinguish. There was no evidence of evaluative conditioning taking place, as CS evaluation did not change during fear acquisition. Early avoidance of the CS+, as deduced from odor inhalation measures, was demonstrated, but did not sustain during the entire acquisition phase. This study suggests that a fear conditioning account of IEI is only partially satisfactory. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Full Text Available Idiopathic pulmonary hemosiderosis (IPH is a rare disorder (triad of iron-deficiency anemia, hemoptysis, and alveolar infiltrates. A 3-year-old male presented with mild fever, breathlessness, dry cough, and bluish nail discoloration for 8 days. He had required five blood transfusions in the past 1 year (last transfusion was given 4 months ago. He had a respiratory rate of 58/min with respiratory distress, cyanosis, and grade III clubbing. Respiratory system examination was normal. Several previous reports of hemoglobin were as low as 3.6 g/dl with hypochromic and microcytic anemia. There were transient increases in the hemoglobin and normalization of red cell morphology with blood transfusions. Serum iron, G6PD enzyme assay, hemoglobin electrophoresis, the sickling test, Coomb′s test, stool and urine analysis, and a Meckel′s scan were normal. HIV antibody and dsDNA were negative. The chest radiograph revealed symmetrical patchy infiltrates sparing lung apices (confirmed on high-resolution computed tomography. Lung biopsy diagnosed pulmonary hemosiderosis (interstitial lung disease with hemosiderin-laden macrophages scattered in the alveoli and areas of fibrosis in the alveolar septa. The patient showed marked clinical improvement in 10 days of therapy with prednisolone. IPH should be listed in the differential diagnosis of a child presenting with unexplained hypochromic, microcytic anemia and respiratory symptoms.

    Previous studies have demonstrated that the rising mortality due to mesothelioma and asbestosis can be predicted from historic asbestos usage. Mortality due to idiopathic pulmonary fibrosis (IPF) is also rising, without any apparent explanation. To compare mortality due to these conditions and examine the relationship between mortality and national asbestos imports. Mortality data for IPF and asbestosis in England and Wales were available from the Office for National Statistics. Data for mesothelioma deaths in England and Wales and historic UK asbestos import data were available from the Health & Safety Executive. The numbers of annual deaths due to each condition were plotted separately by gender, against UK asbestos imports 48 years earlier. Linear regression models were constructed. For mesothelioma and IPF, there was a significant linear relationship between the number of male and female deaths each year and historic UK asbestos imports. For asbestosis mortality, a similar relationship was found for male but not female deaths. The annual numbers of deaths due to asbestosis in both sexes were lower than for IPF and mesothelioma. The strength of the association between IPF mortality and historic asbestos imports was similar to that seen in an established asbestos-related disease, i.e. mesothelioma. This finding could in part be explained by diagnostic difficulties in separating asbestosis from IPF and highlights the need for a more accurate method of assessing lifetime occupational asbestos exposure. © Crown copyright 2015.

    Previous studies have reported the possible contribution of a primitive variant of the basal vein of Rosenthal (BVR) in the cause of idiopathic subarachnoid hemorrhage (ISAH). The purpose of this study was to assess the drainage patterns of the BVR among ISAH patients. The venous phase at cerebral angiography was retrospectively analyzed in 19 patients with ISAH and then compared with patients with unruptured aneurysms as controls. A relationship was found between ISAH and the presence of a primitive variant. However, the venous configuration effect on bleeding is still unknown. Copyright © 2015 Polish Neurological Society.

    Directory of Open Access Journals (Sweden)

    Carlos Renato dos Reis Lemos

    Full Text Available CONTEXT: Chronic idiopathic intestinal pseudo-obstruction is a very rare condition. CASE REPORT: This study describes a male patient who had presented obstructive symptoms for 24 years. He had been treated clinically and had undergone two previous operations in different services, with no clinical improvement or correct diagnosis. He was diagnosed with intestinal obstruction without mechanical factors in our service and underwent jejunostomy, which had a significant decompressive effect. The patient was able to gain weight and presented improvements in laboratory tests. Jejunostomy is a relatively simple surgical procedure that is considered palliative but, in this case, it was resolutive.

    2017-05-01

    Familial cases of idiopathic intracranial hypertension (IIH) are exceedingly rare, and its occurrence in monozygotic twins has not been reported previously. We report monozygotic female twins who developed IIH, one at age 25 years and the other at age 28 years. Continuous intracranial pressure (ICP) monitoring confirmed elevated ICP as measured initially by lumbar puncture. In both cases, successful treatment with resolution of papilledema and symptoms relief was achieved after ventriculoperitoneal shunting. This report documents the first case of IIH in monozygotic twins and the associated changes in ICP dynamics. Interestingly, almost equivalent alterations in ICP dynamics were found in the 2 patients.

    Purpose: To compare clinical and computed tomography (CT) measures in extension, 20{sup o} and 30{sup o} of flexion of symptomatic knees of patient with idiopathic patellofemoral pain syndrome with the contra lateral asymptomatic knee. Materials and methods: Knees of 52 consecutive patients with idiopathic patellofemoral pain were studied with CT. In 28 patients this condition was unilateral and asymptomatic knee was used as control; 76 knees were symptomatic. Results: In patients with idiopathic patellofemoral pain we found a greater Q angle and internal condylar facet width in symptomatic knees with regard to asymptomatic knees. Conclusion: Greater Q angle and medial condylar facet can lead to overpressure on the medial knee compartment during maneuvers that increase contact between patella and medial condylar facet, such as knee flexion and squatting, contributing to development of idiopathic patellofemoral pain.

  19. PATTERN OF INHERITANCE OF IDIOPATHIC HYPERCALCIURIA IN TWO FAMILIES

    Directory of Open Access Journals (Sweden)

    A. Nickavar

    2006-09-01

    Full Text Available Idiopathic hypercalciuria is a leading cause of frequency-dysuria syndrome in childhood. Different modes of inheritance have been suggested in this disease. This article presents the occurrence of idiopathic hypercalciuria in all children of two families. In the first family, a 5.5 year old girl with a history of renal stones and dysuria due to hypercalciuria, had two involved brothers and one sister. In the second family, hypercalciuria and medullary nephrocalcinosis were detected in two siblings who were admitted for polyuria and dysuria. Idiopathic type of hypercalciuria was diagnosed in these two families by normal laboratory exams and exclusion of other causes of normocalcemic hypercalciuria. According to the involvement of all offsprings (both sexes in these two families, it is suggested that idiopathic hypercalciuria is an autosomal dominant disease with complete penetration.

    1999-01-01

    Purpose: To assess the efficacy and safety of microcatheter embolization in the treatment of intractable idiopathic epistaxis. Methods: Thirty-seven patients underwent microcatheter embolization in 1991-1998. We evaluated retrospectively the technical and clinical outcome, the number of complications, the duration of embolization in each case, and the number of blood transfusions needed. All embolizations were done with biplane digital subtraction angiography (DSA) equipment. The procedure was carried out under local anesthesia using transfemoral catheterization, except in one case where the translumbar route was used. Tracker 18 or 10 microcatheters were advanced as far as possible to the distal branches of the sphenopalatine artery. Polyvinyl alcohol (PVA) particles were used for embolization in most cases, while platinum coils or a combination of these two materials were occasionally used. The primary outcome was always assessed immediately by angiography. Follow-up data were obtained from patient records, by interviewing patients on the telephone or by postal questionnaires when necessary. The mean follow-up time was 21 months. Results: The embolization was technically successful in all 37 cases. A curative outcome was achieved in 33 cases (89%). The mean duration of the procedure was 110 min. Four patients (8%) had mild transient complications, but no severe or persistent complications were encountered. Twenty-three patients needed a blood transfusion. Slight rebleeding occurred in three patients during the follow-up; all responded to conservative treatment. One patient suffered two episodes of rebleeding within 2 months after primary embolization. Re-embolizations successfully stopped the bleeding. Conclusion: Embolization is the primary invasive modality for treating intractable idiopathic epistaxis. It proved both safe and effective over a relatively long follow-up

  1. Idiopathic Syringomyelia in a Military Helicopter Pilot.

    2017-10-01

    A syrinx is a fluid-filled cavity within the spinal cord. They can lead to a variety of symptoms, including limb weakness and back pain. Incidental finding of syringomyelia provides a challenge for clinicians due to the wide variety of possible symptoms. In military aviation, neurological findings in pilots can result in extensive investigation that can lead to potentially invasive management. Conversely, the potential for chronic progression of a spinal syrinx and subsequent neurological deterioration makes early identification critical. Ultimately, the discovery of a lesion may have implications for flying status and operational capability. A 25-yr-old man working as a navy Seahawk helicopter pilot presented with episodes of right arm paraesthesia and pain between the scapulae. On at least one occasion, these symptoms woke him at night. Upon magnetic resonance imaging, dilatation of the central canal in a syrinx-like pattern in the lower cervical region was noted. Neurology review suggested the finding was persistent and unlikely to be responsible for his symptoms. No surgical input was recommended. His symptoms were attributed to mild cervical spondylosis, which resolved with ongoing physiotherapy, and he was returned to flying status. This case highlights several issues involved with the incidental finding of a syringomyelia. Surgical intervention has been known to worsen symptoms. Conversely, studies have identified minimal radiological progression in cases of idiopathic syringomyelia, with fewer individuals displaying neurological deterioration. For aircrew, potentially unnecessary neurosurgical intervention poses risks to a flying career and overall operational capability.Schiemer A. Idiopathic syringomyelia in a military helicopter pilot.

    The term idiopathic focal epilepsies of childhood (IFE) is not formally recognised by the ILAE in its 2010 revision (Berg et al., 2010), nor are its members and boundaries precisely delineated. The IFEs are amongst the most commonly encountered epilepsy syndromes affecting children. They are fascinating disorders that hold many "treats" for both clinicians and researchers. For example, the IFEs pose many of the most interesting questions central to epileptology: how are functional brain networks involved in the manifestation of epilepsy? What are the shared mechanisms of comorbidity between epilepsy and neurodevelopmental disorders? How do focal EEG discharges impact cognitive functioning? What explains the age-related expression of these syndromes? Why are EEG discharges and seizures so tightly locked to slow-wave sleep? In the last few decades, the clinical symptomatology and the respective courses of many IFEs have been described, although they are still not widely appreciated beyond the specialist community. Most neurologists would recognise the core syndromes of IFE to comprise: benign epilepsy of childhood with centro-temporal spikes or Rolandic epilepsy (BECTS/RE); Panayiotopoulos syndrome; and the idiopathic occipital epilepsies (Gastaut and photosensitive types). The Landau-Kleffner syndrome and the related (idiopathic) epilepsy with continuous spikes and waves in sleep (CSWS or ESES) are also often included, both as a consequence of the shared morphology of the interictal discharges and their potential evolution from core syndromes, for example, CSWS from BECTS. Atypical benign focal epilepsy of childhood also has shared electro-clinical features warranting inclusion. In addition, a number of less well-defined syndromes of IFE have been proposed, including benign childhood seizures with affective symptoms, benign childhood epilepsy with parietal spikes, benign childhood seizures with frontal or midline spikes, and benign focal seizures of adolescence.

    The ability to recognize and respond to the alarm calls of heterospecifics has previously been described only in species with vocal communication. Here we provide evidence that a non-vocal reptile, the Galápagos marine iguana (Amblyrhynchus cristatus), can eavesdrop on the alarm call of the Galápagos mockingbird (Nesomimus parvulus) and respond with anti-predator behaviour. Eavesdropping on complex heterospecific communications demonstrates a remarkable degree of auditory discrimination in a non-vocal species.

    Neurophysiological studies have shown an impairment of temperature perception in secondary and idiopathic restless legs syndrome (RLS). It is unclear whether these deficits are caused by peripheral nerve fibre damage or by central impairment of somatosensory processing. The aim of the present study was (1) to determine the frequency of thermal hypaesthesia in a large population of secondary and idiopathic RLS patients; (2) to differentiate between a peripheral and central disturbance of somatosensory processing and (3) to correlate these findings with the clinical manifestation of the disease. From the results of clinical examination, nerve conduction studies and blood samples the patients were divided into secondary and idiopathic RLS groups. The severity of RLS symptoms was assessed by standardized questionnaires. Quantitative sensory testing (QST) assessing temperature perception was performed in all patients. The peripheral function of small nerve fibres was evaluated by the quantitative nociceptor axon reflex test (QNART). 22 secondary and 20 idiopathic RLS patients participated in the study. Impairment of temperature perception (QST) was found in 72% of the secondary RLS patients and in 55% of idiopathic RLS patients. The peripheral C-fibre function (QNART) was normal in idiopathic RLS patients. In contrast it was significantly impaired in secondary RLS patients compared with idiopathic RLS patients and age matched controls. There was no correlation between the results obtained in QST and clinical scores. Impairment of temperature perception is present in a high percentage of RLS patients. In secondary RLS the sensory deficits are at least in part caused by small fibre neuropathy. In idiopathic RLS a functional impairment of central somatosensory processing is present.

    To investigate obesity as susceptibility factor in patients with idiopathic AA amyloidosis. Clinical, biochemical and genetic data were obtained from 146 patients with AA amyloidosis. Control groups comprised 40 patients with long-standing inflammatory diseases without AA amyloidosis and 56 controls without any inflammatory disease. Patients with AA amyloidosis had either familial Mediterranean fever (FMF) or long-standing rheumatic diseases as underlying inflammatory disease (n = 111, median age 46 years). However, in a significant proportion of patients with AA amyloidosis no primary disease was identified (idiopathic AA; n = 37, median age 60 years). Patients with idiopathic AA amyloidosis were more obese and older than patients with AA amyloidosis secondary to FMF or rheumatic diseases. Serum leptin levels correlated with the body mass index (BMI) in all types of AA amyloidosis. Elevated leptin levels of more than 30 µg/l were detected in 18% of FMF/rheumatic + AA amyloidosis and in 40% of patients with idiopathic AA amyloidosis (p = .018). Finally, the SAA1 polymorphism was confirmed as a susceptibility factor for AA amyloidosis irrespective of the type of the disease. Obesity, age and the SAA1 polymorphism are susceptibility factors for idiopathic AA amyloidosis. Recent advances in treatment of FMF and rheumatic disorders will decrease the incidence of AA amyloidosis due to these diseases. Idiopathic AA, however, might be an emerging problem in the ageing and increasingly obese population.

    To determine whether patients with idiopathic and symptomatic RBD were sleepier than controls, and if sleepiness in idiopathic RBD predicted earlier conversion to Parkinson disease. The Epworth Sleepiness Scale (ESS) and its determinants were compared at the time of a video-polysomnography for an RBD diagnosis in patients with idiopathic RBD, in patients with Parkinson disease, and in controls. Whether sleepiness at time of RBD diagnosis predicted an earlier conversion to neurodegenerative diseases was retrospectively analyzed in the followed-up patients. The 75 patients with idiopathic RBD were sleepier (ESS: 7.8 ± 4.6) at the time of RBD diagnosis than 74 age- and sex-matched controls (ESS: 5.0 ± 3.6, P sleep measures. Among the 69 patients with idiopathic RBD who were followed up for a median 3 years (1-15 years), 16 (23.2%) developed parkinsonism (n = 6), dementia (n = 6), dementia plus parkinsonism (n = 2), and multiple system atrophy (n = 2). An ESS greater than 8 at time of RBD diagnosis predicted a shorter time to phenoconversion to parkinsonism and dementia, from RBD onset, and from RBD diagnosis (when adjusted for age and time between RBD onset and diagnosis). Sleepiness is associated with idiopathic REM sleep behavior disorder and predicts more rapid conversion to parkinsonism and dementia, suggesting it is an early marker of neuronal loss in brainstem arousal systems. © 2015 Associated Professional Sleep Societies, LLC.

    Increasing evidence suggests a role of gastro-oesophageal reflux (GER) in idiopathic pulmonary fibrosis (IPF) pathogenesis. Recently, an association between serum Helicobacter pylori (HP) antibody positivity and more severe disease was described, but HP has not been directly analysed in lung tissue so far. To investigate the presence of HP in the lung tissue of IPF patients. Two tertiary interstitial lung disease care centre databases were screened for available lung biopsy material from IPF patients. Clinical and radiological data, including presence of GER and antiacid medication, were evaluated. HP-specific PCR was carried out on the IPF lung biopsy specimens. A total of 39 IPF patients were included, of whom 85% were male. The patients' median age was 66 years, their vital capacity was 79% predicted, and their diffusing capacity for carbon monoxide was 53% predicted. In all, 82% of the lung biopsies were surgical and 18% transbronchial. Comorbidities were GER disease in 23% (n = 9), sleep apnoea in 13% (n = 5) and hiatal hernia in 38% of the cases (n = 15). Proton pump inhibitors were prescribed at the time of biopsy in 21% of the cases (n = 9). After a median follow-up of 25 months (range 6-69), there were 1 death, 1 lung transplantation and 8 acute exacerbations without relevant differences between the GER and non-GER subgroups. HP DNA was not detected in any of the lung tissue samples. The fact that no HP DNA was detected in the lung tissues calls into question the proposed relevance of HP to the direct pathogenesis of IPF. © 2015 S. Karger AG, Basel.

    Full Text Available Abstract Background Idiopathic pulmonary fibrosis (IPF is a devastating interstitial pneumonia causing a loss of respiratory surface area due to a proliferative fibrotic response involving hyperplastic, hypertrophic, and metaplastic epithelium, cystic honeycomb change, septal expansion, and variable inflammation. Wnt (wingless signaling glycoproteins are known to be involved in lung development and tissue repair, and are up-regulated in patients with IPF. Based on previous qRT-PCR data showing increased Wnt7B in lungs of IPF patients, a systematic, quantitative examination of its tissue site distribution was undertaken. Methods Tissue samples from the Lung Tissue Research Consortium (LTRC of 39 patients diagnosed with mild to severe IPF/usual interstitial pneumonia (UIP and 19 normal patients were examined for the immunolocalization of Wnt7B. Results In normal lung, moderate Wnt7B reactivity was confined to airway epithelium, smooth muscle of airways and vasculature, and macrophages. IPF lung showed strong Wnt7B reactivity in fibroblastic foci, dysplastic airway and alveolar epithelium, and in highly discrete subepithelial, basement membrane-associated regions. All reactive sites were sized and counted relative to specific microscopic regions. Those in the subepithelial sites were found in significantly greater numbers and larger relative area compared with the others. No reactive sites were present in normal patient controls. Conclusions The results demonstrate Wnt7B to be expressed at high concentrations in regions of active hyperplasia, metaplasia, and fibrotic change in IPF patients. In this context and its previously established biologic activities, Wnt7B would be expected to be of potential importance in the pathogenesis of IPF.

    It has previously been shown that rotational stability of spinal segments is reduced by posteriorly directed shear loads that are the result of gravity and muscle tone. Posterior shear loads act on those segments of the spine that are posteriorly inclined, as determined by each individual's inherited sagittal spinal profile. Accordingly, it can be inferred that certain sagittal spinal profiles are more prone to develop a rotational deformity that may lead to idiopathic scoliosis; and lumbar scoliosis, on one end of the spectrum, develops from a different sagittal spinal profile than thoracic scoliosis on the other end. To examine the role of sagittal spinopelvic alignment in the etiopathogenesis of different types of idiopathic scoliosis. Multicenter retrospective analysis of lateral radiographs of patients with small thoracic and lumbar adolescent idiopathic scoliotic curves. We included 192 adolescent idiopathic scoliosis patients with either a thoracic (n=128) or lumbar (n=64) structural curve with a Cobb angle of less than 20° were studied. Children with other spinal pathology or with more severe idiopathic scoliosis were excluded, because this disturbs their original sagittal profile. Subjects who underwent scoliosis screening and had a normal spine were included in the control cohort (n=95). Thoracic kyphosis, lumbar lordosis, T9 sagittal offset, C7 and T4 sagittal plumb lines, pelvic incidence, pelvic tilt, and sacral slope, as well as parameters describing orientation in space of each individual vertebra between C7 and L5 and length of the posteriorly inclined segment. On standardized lateral radiographs of the spine, a systematic, semi-automatic measurement of the different sagittal spinopelvic parameters was performed for each subject using in-house developed computer software. Early thoracic scoliosis showed a significantly different sagittal plane from lumbar scoliosis. Furthermore, both scoliotic curve patterns were different from controls, but in a

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

Moore, MD, FAAP, FACR, MACR Professor of Internal Medicine,Pediatrics, and Molecular Biology and Immunology Director of Adult and Pediatric Rheumatology Saint Louis University School of Medicine Saint Louis, Missouri 631`04,USA Juvenile idiopathic arthritis (JIA reflects a group of clinically heterogeneous, autoimmune disorders in children characterized by chronic arthritis and hallmarked by elevated levels of circulating immune complexes (CICs and associated complement activation by-products in their sera. ICs have been detected in patients’ sera with JIA utilizing a variety of methods, including the anti-human IgM affinity column,C1q solid phase assay, polyethylene glycol precipitation, Staphylococcal Protein A separation method, anti-C1q/C3 affinity columns, and FcγRIII affinity method. As many as 75% of JIA patients have had IC detected in their sera. The CIC proteome in JIA patients has been examined to elucidate disease-associated proteins that are expressed in active disease. Evaluation of these IC s have shown the presence of multiple peptide fragments by SDS-PAGE and 2-DE. Subsequently, all isotypes of rheumatoid factor (RF, isotypes of anti-cyclic citrullinated (CCP peptide antibodies, IgG, C1q, C4, C3, and the membrane attack complex (MAC were detected in these IC. Complement activation and levels of IC correlate with disease activity in JIA, indicating their role in the pathophysiology of the disease. This review will summarize the existing literature and discuss the role of possible protein modification that participates in the generation of immune response. We will address the possible role of these events in the development of ectopic germinal centers that become the secondary site of plasma cell development in JIA. We

    Full Text Available Background : DNA methylation is an important epigenetic feature of DNA that plays a pivotal role in gene expression regulation during spermatogenesis. The enzyme methylenetetrahydrofolate reductase (MTHFR catalyses the formation of folate intermediates that are vital for DNA synthesis and methylation reactions. C677T and A1298C variants of MTHFR result in reduced plasma folate and increase the susceptibility to various multifactorial disorders. We have already shown that homozygosity for 677 (C ®T mutation in the MTHFR gene, is a risk factor for idiopathic male infertility in an Indian population. Aim: Recently, we showed that homozygosity for the 677(C;T mutation in the MTHFR gene is a risk factor for idiopathic male infertility and now we aim to assess whether the A1298C mutation in the same gene is an additional risk factor for idiopathic male infertility in an Indian population. Setting and Designs : In a case-control study 151 idiopathic male infertile patients and 140 healthy fertile control individuals were recruited from the University hospital and infertility clinics in Varanasi city, India. Materials and Methods: Genotyping for A1298C change of the MTHFR gene was done by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP method. Statistical Analysis : Allele frequencies were calculated using Fisher′s exact test. Odds ratio was calculated as the measure of the association between the MTHFR genotype and idiopathic male infertility. Results : The homozygous (C/C A1298C polymorphism of the MTHFR gene was present at a statistically high significance in idiopathic azoospermic infertile men (OR=3.4494, CI: 1.0092 to 11.7899, P<0.05. Conclusion : The MTHFR 1298CC genotype is an additional genetic risk factor for idiopathic male infertility in an Indian population.

    Brace treatment is the gold standard for patients with mild adolescent idiopathic scoliosis (Cobb angle 20°-40°). However, negative psychosocial impacts, physical constraints and incompliance cause many patients and parents to seek for so-called holistic and apparently less harmful approaches within the field of complementary and alternative medicine (CAM). Osteopathy-manual interventions on the viscera and locomotor system-is widely used for scoliosis. There is, however, a complete lack of evidence regarding its efficacy. We, therefore, tested the hypothesis that osteopathy alters trunk morphology, a prerequisite to unload the concave side of the scoliosis, and that it halts curve progression. This was a prospective, controlled trial of 20 post-pubertal young women (20°-40° idiopathic scoliosis) randomly allocated to an observation (group 0) or osteopathic treatment (group 1). The latter comprised three sessions (5 weeks). Trunk morphology (clinical examination, video rasterstereography) and spine flexibility (MediMouse(®)) were assessed at a pre- and post-intervention with a 3-month interval (blinded examiner). We chose scoliometer measurement (rib hump, lumbar prominence) as the main outcome parameter. Two patients in the treatment group refused further treatment and the final examination, as they felt no benefit after two osteopathic treatments. Regression analysis for repeat measurements (independent statistician) revealed no therapeutic effect on rib hump, lumbar prominence, plumb line, sagittal profile and global spinal flexibility. We found no evidence to support osteopathy in the treatment of mild adolescent idiopathic scoliosis. Therefore, we caution against abandoning the conventional standard of care for mild idiopathic scoliosis. As for other CAM therapies, the use of osteopathy as a treatment option for scoliosis still needs to be clearly defined.

    Introduction: Scoliosis is a complex three-dimensional spine deformity with the frontal plane deflexion (side-shift) of the series of vertebra from the midline and with torque deformity of vertebra, ribs, and the entire trunk towards the apex of curve. Chronic venous diseases present a group of pathological conditions caused by the increased venous pressure. The venous pressure may be increased due to genetics, ligament laxity, general obesity, injuries, and changes in biomechanics of spine and lower extremities, etc. Aim: The aim of the study is to evaluate the frequency of the varicose veins in women previously treated for the adolescent idiopathic scoliosis. Material and methods: In the period August 1, 2015 - December 30, 2015 the Team for scoliosis in the Institute for the Physical medicine and Rehabilitation „Dr Miroslav Zotović” in Banja Luka in study program has clinically assessed 89 women previously treated for the adolescent idiopathic scoliosis (AIS) and the control group of 87 women without history of scoliosis. Results: Results of the study led to conclusion that occurrence of the varicose veins was more frequent in the group of women who were treated for the AIS (23/89 or 25.8%) in comparison with control group with no history of AIS (7/87 or 8.1%). Conclusion: This might relate AIS with some other connective tissue disorder, like venous varices, for instance. PMID:28790540

    Idiopathic pulmonary fibrosis (IPF) is an incurable complex genetic disorder that is associated with sequence changes in 7 genes (MUC5B, TERT, TERC, RTEL1, PARN, SFTPC, and SFTPA2) and with variants in at least 11 novel loci. We have previously found that 1) a common gain-of-function promoter variant in MUC5B rs35705950 is the strongest risk factor (genetic and otherwise), accounting for 30-35% of the risk of developing IPF, a disease that was previously considered idiopathic; 2) the MUC5B promoter variant can potentially be used to identify individuals with preclinical pulmonary fibrosis and is predictive of radiologic progression of preclinical pulmonary fibrosis; and 3) MUC5B may be involved in the pathogenesis of pulmonary fibrosis with MUC5B message and protein expressed in bronchiolo-alveolar epithelia of IPF and the characteristic IPF honeycomb cysts. Based on these considerations, we hypothesize that excessive production of MUC5B either enhances injury due to reduced mucociliary clearance or impedes repair consequent to disruption of normal regenerative mechanisms in the distal lung. In aggregate, these novel considerations should have broad impact, resulting in specific etiologic targets, early detection of disease, and novel biologic pathways for use in the design of future intervention, prevention, and mechanistic studies of IPF.

    Longitudinal cohort study. To compare functional outcomes between male and female patients before and after surgery for adolescent idiopathic scoliosis (AIS). There is no clear consensus in the existing literature with respect to sex differences in functional outcomes in the surgical treatment of AIS. A prospective, consecutive, multicenter database of patients who underwent surgical correction for adolescent idiopathic scoliosis was analyzed retrospectively. All patients completed Scoliosis Research Society-30 (SRS-30) questionnaires before and 2 years after surgery. Patients with previous spine surgery were excluded. Data were collected for sex, age, Risser grade, previous bracing history, maximum preoperative Cobb angle, curve correction at 2 years, and SRS-30 domain scores. Paired sample t tests were used to compare preoperative and postoperative scores within each sex. Independent sample t tests were used to compare scores between sexes. A P value of Self-image/appearance had the greatest relative improvement. Males had better self-image/appearance scores preoperatively, better pain scores at 2 years, and better mental health and total scores both preoperatively and at 2 years. Both males and females were similarly satisfied with surgery. Males treated with surgery for AIS report better preoperative self-image, less postoperative pain, and better mental health than females. These differences may be clinically significant. For both males and females, the most beneficial effect of surgery is improved self-image/appearance. Overall, the benefits of surgery for AIS are similar for both sexes.

    Full Text Available There have been great advances in the conservative and surgical treatment for adolescent idiopathic scoliosis in the last few decades. The challenge for the physician is the decision for the optimal time to institute therapy for the individual child. This makes an understanding of the natural history and risk factors for curve progression of significant importance. Reported rates of curve progression vary from 1.6% for skeletally mature children with a small curve magnitude to 68% for skeletally immature children with larger curve magnitudes. Although the patient′s age at presentation, the Risser sign, the patient′s menarchal status and the magnitude of the curve have been described as risk factors for curve progression, there is evidence that the absolute curve magnitude at presentation may be most predictive of progression in the long term. A curve magnitude of 25º at presentation may be predictive of a greater risk of curve progression. Advances in research may unlock novel predictive factors, which are based on the underlying pathogenesis of this disorder.

    Chronic idiopathic urticaria (CIU) is a common dermatological condition. Its pathogenesis involves mainly histamine and also other mediators, including platelet-activating factor (PAF) and tumor necrosis factor-α (TNF-α). In the absence of an exact etiology, H1 -antihistaminics are the mainstay of treatment. Levocetirizine is widely prescribed for CIU. Rupatadine, a newer antihistaminic, has PAF receptor antagonist activity and has shown anti-TNF-α activity in vitro. These additional anti-inflammatory effects may improve its efficacy. This study was conducted to compare the efficacy and safety of rupatadine and levocetirizine, respectively, in CIU patients. A prospective, open, comparative, randomized study was conducted in 100 patients, of whom 50 were treated with levocetirizine and 50 were treated with rupatadine. Efficacy parameters used were urticarial activity score (UAS) and Dermatology Life Quality Index (DLQI) values. Safety was evaluated by monitoring for adverse drug reactions and by using the critical flicker fusion threshold (CFFT) test and a visual analog scale (VAS) at baseline, and at 2, 4, and 6 weeks. The mean UAS decreased to 0.10 in the levocetirizine group and to 0.38 in the rupatadine group. Patients in the levocetirizine group showed a more significant (P drugs caused mild sedation. © 2014 The International Society of Dermatology.

    Optic neuritis (ON) was rarely reported in juvenile idiopathic arthritis (JIA) patients, particularly in those under anti-tumor necrosis factor alpha blockage. However, to our knowledge, the prevalence of ON in JIA population has not been studied. Therefore, 5,793 patients were followed up at our University Hospital and 630 (11%) had JIA. One patient (0.15%) had ON and was reported herein. A 6-year-old male was diagnosed with extended oligoarticular JIA, and received naproxen and methotrexate subsequently replaced by leflunomide. At 11 years old, he was diagnosed with aseptic meningitis, followed by a partial motor seizure with secondary generalization. Brain magnetic resonance imaging (MRI) and electroencephalogram showed diffuse disorganization of the brain electric activity and leflunomide was suspended. Seven days later, the patient presented acute ocular pain, loss of acuity for color, blurred vision, photophobia, redness and short progressive visual loss in the right eye. A fundoscopic exam detected unilateral papilledema without retinal exudates. Orbital MRI suggested right ON. The anti-aquaporin 4 (anti-AQP4) antibody was negative. Pulse therapy with methylprednisolone was administered for five days, and subsequently with prednisone, he had clinical and laboratory improvement. In conclusion, a low prevalence of ON was observed in our JIA population. The absence of anti-AQP4 antibody and the normal brain MRI do not exclude the possibility of demyelinating disease associated with chronic arthritis. Therefore, rigorous follow up is required.

    Juvenile idiopathic arthritis (JIA) is the most common autoimmune inflammatory disease of connective tissue in children. It is characterized by progressive joint destruction which causes preserved changes in the musculoskeletal system. The literature describes fully clinical symptoms and radiological images in different subtypes of JIA. However, there is still a limited number of studies reporting on the medical condition of the oral cavity of ill children. JIA can affect hard and soft tissues of the oral cavity by: the general condition of the child's health, arthritis of the upper limbs, as the result of the pharmacotherapy, changes in secretion and composition of saliva, inflammation of the temporomandibular joint and facial deformity. The study summarizes the available literature on the condition of the teeth and periodontal and oral hygiene in the course of JIA. The presence of diverse factors that modify the oral cavity, such as facial growth, functioning of salivary glands, or the supervision and care provided by adults, prevents clear identification if JIA leads to severe dental caries and periodontal disease. Despite conflicting results in studies concerning the clinical oral status, individuals with JIA require special attention regarding disease prevention and maintenance of oral health.

    Objective was to describe the clinical features of 5 patients with rare atypical presentation of idiopathic intracranial hypertension (IIH), and propose the possible mechanism of this atypical presentation. We carried out a retrospective study of 5 patients, admitted at King Khalid National Guard Hospital, Jeddah, Kingdom of Saudi Arabia with IIH during the period from January 2001 to December 2005. All were females with their age ranges from 24 to 40 years. The clinical presentations, the laboratory and imaging studies were analyzed. The opening pressures of the lumbar puncture tests were documented. All patients were presented with headache. One had typical pain of trigeminal neuralgia and one with neck pain and radiculopathy. Facial diplegia was present in one patient and two patients had bilateral 6th cranial neuropathy. Papilledema was present in all patients except in one patient. Imaging study was normal in all patients, and they had a very high opening pressure during lumbar puncture, except in one patient. All patients achieved full recovery with medical therapy in 6 to 12 weeks with no relapse during the mean follow up of 2 years. Atypical finding in IIH are rare and require a high index of suspicion for early diagnosis. (author)

    2016-01-01

    Juvenile idiopathic arthritis (JIA) comprises a group of heterogeneous disorders of chronic arthritis in childhood and remains the commonest pediatric rheumatic disease associated with significant long-term morbidity. Advances in understanding of the pathogenesis, better definition of disease control/remission measures, and the arrival of biological agents have improved the outcomes remarkably. Methotrexate (Mtx) remains the first-line disease modifying (DMARD) therapy for most children with JIA due to its proven efficacy and safety. Sulphosalazine (SSz) (especially for enthesitis) and leflunomide may also have a secondary role. Tumor necrosis factor inhibitors (TNF-I), alone or in combination with Mtx have shown tremendous benefit in children with polyarticular JIA, enthesitis related arthritis (ERA) and psoriatic arthritis. Tocilizumab appears very efficacious in systemic arthritis and abatacept and tocilizumab also appear to benefit polyarticular JIA; the role of rituximab remains unclear, though clearly beneficial in adult RA. TNF-I with Mtx is also effective in uveitis associated with JIA. Biologicals have demonstrated an impressive safety record in children with JIA, although close monitoring for rare but potentially dangerous adverse events, such as tuberculosis and other infections; paradoxical development of additional autoimmune diseases; and possibly an increased risk of cancers is warranted.

    Full Text Available The pathogenesis of idiopathic non-cirrhotic portal hypertension (INCPH remains unknown and the disease is diagnosed by the absence of recognized clinical indicators of cirrhosis and of any other known etiologies of portal hypertension. To promote understanding of this disease, a comprehensive overview of potential etiologies, clinical manifestations, histopathological features, methods of diagnosis and potential differential diagnoses, and outcome of clinical management is presented in this review. In particular, we discuss the findings from INCPH studies and their implications in regards to each of the above-mentioned categories. For example, associations with various comorbidities have suggested a possible immune system component to INCPH development and/or progression. In addition, the common clinical characteristics of patients upon presentation can not only help to recognize disease suspects but may also provide insights into the pathogenesis and prognosis. Finally, prognosis following the various intervention strategies appears to depend mainly on severity of the portal hypertension, as well as its various accompanying complications.

    In ∼20 to 30% of patients with systemic mastocytosis (SM), an associated clonal hematological nonmast cell lineage disorder (AHNMD) is diagnosed. Although SM may be considered to be closely related to the myeloproliferative disorders (MPDs), it is unknown whether JAK2V617F+ MPD may occur as AHNMD in patients with SM. We here describe five patients with SM and co-existing chronic idiopathic myelofibrosis (SM-CIMF). In five of five patients, we detected the SM-related KIT mutation D816V, and in four of five patients, the MPD-related JAK2 mutation V617F. Surprisingly, JAK2V617F was found not only in the AHMMD component of the disease but also in microdissected mast cells in all four JAK2V617F-positive cases. Conversely, in two of the five patients, KITD816V was found not only in neoplastic mast cells but also in microdissected CD15+ neoplastic myeloid cells. Control experiments showed that 10 indolent SM patients without associated MPD did not carry the JAK2 mutation V617F and that 15 CIMF patients without SM did not carry the KIT mutation D816V. Altogether, these data suggest that KITD816V+ SM can co-exist with JAK2V617F+ CIMF and that, in some of these SM-CIMF cases, the two mutations are present in the neoplastic cells of both disease components.

    Full Text Available Magnetic resonance imaging (MRI techniques have been used to quantitatively assess focal and network abnormalities. Idiopathic generalized epilepsy (IGE is characterized by bilateral synchronous spike–wave discharges on electroencephalography (EEG but normal clinical MRI. Dysfunctions involving the neocortex, particularly the prefrontal cortex, and thalamus likely contribute to seizure activity. To identify possible morphometric and functional differences in the brains of IGE patients and normal controls, we employed measures of thalamic volumes, cortical thickness, gray–white blurring, fractional anisotropy (FA measures from diffusion tensor imaging (DTI and fractional amplitude of low frequency fluctuations (fALFF in thalamic subregions from resting state functional MRI. Data from 27 patients with IGE and 27 age- and sex-matched controls showed similar thalamic volumes, cortical thickness and gray–white contrast. There were no differences in FA values on DTI in tracts connecting the thalamus and prefrontal cortex. Functional analysis revealed decreased fALFF in the prefrontal cortex (PFC subregion of the thalamus in patients with IGE. We provide minimum detectable effect sizes for each measure used in the study. Our analysis indicates that fMRI-based methods are more sensitive than quantitative structural techniques for characterizing brain abnormalities in IGE.

    To assess the effect of testosterone deficiency on skeletal integrity in men, we determined bone density in 23 hypogonadal men with isolated gonadotropin-releasing hormone deficiency and compared those values with ones from controls. Cortical bone density, as assessed by single-photon absorptiometry of the nondominant radius, ranged from 0.57 to 0.86 g/cm2 (mean +/- SE, 0.71 +/- 0.02) in patients with fused epiphyses and from 0.57 to 0.67 g/cm2 (mean, 0.61 +/- 0.01) in patients with open epiphyses, both of which were significantly (p less than 0.001) lower than normal. Spinal trabecular bone density, as assessed by computed tomography, was similarly decreased (p less than 0.0001) and ranged from 42 to 177 mg K2HPO4/cm3 (mean, 112 +/- 7). Cortical bone density was at least 2 SD below normal in 16 of 23 men, and 8 men had spinal bone densities below the fracture threshold of 80 to 100 mg K2HPO4/cm3. Osteopenia was equally severe in men with immature and mature bone ages, suggesting that abnormal bone development plays an important role in the osteopenia of men with idiopathic hypogonadotropic hypogonadism.

    Full Text Available The primary function of the lymphatic system is absorbing and transporting macromolecules and immune cells to the general circulation, thereby regulating fluid, nutrient absorption and immune cell trafficking. Lymphangiogenesis plays an important role in tissue inflammation and tumour cell dissemination. Lymphatic involvement is seen in lymphangioleiomyomatosis (LAM and idiopathic pulmonary fibrosis (IPF. LAM, a disease primarily affecting females, involves the lung (cystic destruction, kidney (angiomyolipoma and axial lymphatics (adenopathy and lymphangioleiomyoma. LAM occurs sporadically or in association with tuberous sclerosis complex (TSC. Cystic lung destruction results from proliferation of LAM cells, which are abnormal smooth muscle-like cells with mutations in the TSC1 or TSC2 gene. Lymphatic abnormalities arise from infiltration of LAM cells into the lymphatic wall, leading to damage or obstruction of lymphatic vessels. Benign appearing LAM cells possess metastatic properties and are found in the blood and other body fluids. IPF is a progressive lung disease resulting from fibroblast proliferation and collagen deposition. Lymphangiogenesis is associated with pulmonary destruction and disease severity. A macrophage subset isolated from IPF bronchoalveolar lavage fluid (BALF express lymphatic endothelial cell markers in vitro, in contrast to the same macrophage subset from normal BALF. Herein, we review lymphatic involvement in LAM and IPF.

    Full Text Available Background: Idiopathic granulomatous mastitis (IGM is an uncommon benign chronic inflammatory breast disease, and erythema nodosum (EN is an extremely rare systemic manifestation of IGM. Here, we report a rare case of IGM accompanied by EN. Case Report: A 32-year-old patient was admitted to our clinic with a history of a tender mass in the right breast. On physical examination, the right breast contained a hard, tender mass in the lower half with in-drawing of the nipple. She had florid EN affecting both legs. She was evaluated with mammography, ultrasound, power Doppler ultrasound, non-enhancing magnetic resonance imaging (MRI, dynamic contrast-enhanced MRI, fine needle aspiration biopsy (FNAB and excisional biopsy. Time-intensity curves showed a type II pattern on dynamic contrast-enhanced MRI, which has an intermediate probability for malignancy. The FNAB reported a benign cytology suggestive of a granulomatous inflammation, which was also supported by the histopathological findings. A partial mastectomy was performed following medical treatment. There was no recurrence at 1-year follow-up. Conclusion: IGM should be considered in the differential diagnosis of EN. Although histopathological examination remains the only method for the definite diagnosis of IGM, MRI can be helpful in the diagnosis or differentiation of benign lesions from malignant ones.

    Full Text Available Idiopathic pulmonary hemosiderosis (IPH is a rare cause of diffuse alveolar hemorrhage with unknown etiology. In the present report, the presentations of two sisters are described: one sister had IPH, eosinophilia and a high serum immunoglobulin E (IgE level; and the other had IPH, pneumothorax, eosinophilia and a high serum IgE level. Both cases had quite unusual presentations. The first patient was 23 years of age, and had suffered from dry cough and progressive dyspnea for four years. Her hemoglobin level was 60 g/L, total serum IgE level was 900 U/mL and eosinophilia was 9%. Her chest radiography revealed diffuse infiltration. She died due to respiratory failure. The second patient was 18 years of age. She had also suffered from dry cough and gradually increasing dyspnea for two years. She had partial pneumothorax in the right lung and diffuse infiltration in other pulmonary fields on chest radiography. Her hemoglobin level was 99 g/L, total serum IgE level was 1200 U/mL and eosinophilia was 8%. IPH was diagnosed by open lung biopsy. All these findings suggested that familial or allergic factors, as well as immunological factors, might have contributed to the etiology of IPH.

    Gastaut type idiopathic childhood occipital epilepsy is an uncommon epileptic syndrome characterised by frequent seizures, most commonly presenting as elementary visual hallucinations or blindness. Other occipital (non-visual) symptoms may also occur. Interictal EEG typically shows occipital paroxysms, often with fixation-off sensitivity. Ictal EEG is usually characterised by interruption by paroxysms and sudden appearance of low-voltage, occipital, fast rhythm and/or spikes. Despite well described clinical and EEG patterns, to our knowledge, there are very few reports in the literature with video-EEG recording of either seizure semiology or fixation-off phenomena. We present a video-EEG recording of a 12-year-old girl with Gastaut type epilepsy, illustrating the interictal and ictal aspects of this syndrome. Our aim was to demonstrate the clinical and neurophysiological pattern of a typical seizure of Gastaut type epilepsy, as well as the fixation-off phenomena, in order to further clarify the typical presentation of this syndrome.

    Full Text Available Background/Aims: Frontal lobe dysfunction is believed to be a primary cognitive symptom in idiopathic normal pressure hydrocephalus (iNPH; however, the neuropsychology of this disorder remains to be fully investigated. The objective of this study was to delineate a comprehensive profile of cognitive dysfunction in iNPH and evaluate the effects of cerebrospinal fluid (CSF shunt surgery on cognitive dysfunction. Methods: A total of 32 iNPH patients underwent neuropsychological testing of memory, attention, language, executive function, and visuoperceptual and visuospatial abilities. Of these 32 patients, 26 were reevaluated approximately 1 year following CSF shunt surgery. The same battery of tests was performed on 32 patients with Alzheimer’s disease (AD and 30 healthy elderly controls. Results: The iNPH patients displayed baseline deficits in attention, executive function, memory, and visuoperceptual and visuospatial functions. Impairments of attention, executive function, and visuoperceptual and visuospatial abilities in iNPH patients were more severe than in those with AD, whereas the degree of memory impairment was comparable to that in AD patients. A significant improvement in executive function was observed following shunt surgery. Conclusion: Patients with iNPH are impaired in various aspects of cognition involving both ‘frontal’ executive functions and ‘posterior cortical’ functions. Shunt treatment can ameliorate executive dysfunction.

    The objective was to identify and evaluate factors that may influence the recovery rate in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). A retrospective analysis was performed for patients with sudden sensorineural hearing loss between 2009 and 2013. Those with an identified etiology were excluded. The patients were divided into four treatment groups: (i) systemic corticosteroids (SC) only, (ii) SC+low-molecular-weight heparin (LMWH), (iii) SC+hyperbaric oxygen (HBO), and (iv) SC+LMWH+HBO. Recovery was evaluated according to Siegel's criteria. Age, initial hearing level, onset, treatment and audiogram types, comorbidities, and associated tinnitus and vestibular symptoms were investigated for their impact on prognosis. Two hundred five patients with ISSNHL were included. Recovery was seen in 59% of the patients. The complete recovery rate was significantly lower in patients older than 60 years and in patients presenting with profound hearing loss. Different audiogram curves had no significant effect on recovery. Sudden hearing loss was accompanied by tinnitus in 107 (52.1%) patients and vestibular symptoms in 55 (26.8%); however, neither was noted to affect prognosis. Different treatment combinations did not significantly affect prognosis. However, hypertension and a delay in treatment by more than 10 days from the onset of hearing loss were associated with a worse prognosis. Profound hearing loss, older than 60 years, a delay in treatment by more than 10 days, and hypertension were negative prognostic factors in this study, whereas, the type of audiogram curve and addition of HBO to SC did not affect prognosis.

    2015-06-01

    Full Text Available Idiopathic inflammatory myositis (IIM is a group of rare connective tissue diseases (CTDs characterised by muscular and extramuscular signs, in which lung involvement is a challenging issue. Interstitial lung disease (ILD is the hallmark of pulmonary involvement in IIM, and causes morbidity and mortality, resulting in an estimated excess mortality of 50% in some series. Except for inclusion body myositis, these extrapulmonary disorders are associated with the general and visceral involvement frequently found in other CTDs including fever, Raynaud's phenomenon, arthralgia, nonspecific cutaneous modifications and ILD, for which the prevalence is estimated to be up to 65%. Substantial heterogeneity exists within the spectrum of IIMs, and each condition is associated with various frequencies and subtypes of pulmonary involvement. This heterogeneity is partly related to the presence of various autoantibodies encompassing anti-synthetase, anti-MDA5 and anti-PM/Scl. ILD is present in all subsets of IIM including juvenile myositis, but is more frequent in dermatomyositis and overlap myositis. IIM can also be associated with other presentations of respiratory involvement, namely pulmonary arterial hypertension, pleural disease, infections, drug-induced toxicity, malignancy and respiratory muscle weakness. Here, we critically review the current knowledge about adult and juvenile myositis-associated lung disease with a detailed description of therapeutics for chronic and rapidly progressive ILD.

    Full Text Available Plastic bronchitis is a rare disorder characterized by formation of large, branching bronchial casts, which are often expectorated. We present an interesting case of a 35-year-old woman who presented for evaluation of a chronic cough productive of voluminous secretions. Clinical and radiological examination confirmed a total left lung atelectasis without any pathological mediastinal node. Flexible bronchoscopy demonstrated tenacious, thick, and sticky whitish secretions blocking the left stem bronchus. This material was extracted, and inspection demonstrated a bronchial cast, whose pathological analysis revealed necrotic epithelial cells, some eosinophils, and Charcot-Leyden crystals. Two days after bronchoscopy, the patient rejected more bronchial casts, and dyspnea improved. Control of chest x-ray revealed complete left lung aeration and the diagnosis of idiopathic plastic bronchitis was obtained. This article shows the interest in clinical practice to evoke the diagnosis of plastic bronchitis in front of a productive chronic cough. Our case illustrates a rare clinical presentation represented by an atelectasis of an entire lung.

    In the United Kingdom, lower incidences of intraspinal abnormalities in patients with early onset idiopathic scoliosis have been observed than in studies in other countries. We aimed to determine the rates of these abnormalities in United Kingdom patients diagnosed with idiopathic scoliosis before the age of 11 years. This retrospective study of patients attending an urban scoliosis clinic identified 71 patients satisfying a criteria of: clinical diagnosis of idiopathic scoliosis; age of onset ten years and 11 months or less; MRI screening for intraspinal abnormalities. United Kingdom census data combined with patient referral data was used to calculate incidence. Mean age at diagnosis was six years with 39 right-sided and 32 left-sided curves. Four patients (5.6%) were found to have intraspinal abnormalities on MRI. These consisted of: two combined Arnold-Chiari type 1 malformations with syrinx; one syrinx with a low lying conus; and one isolated syrinx. Overall annual incidence of early onset idiopathic scoliosis was one out of 182 000 (0.0006%). This study reports the lowest rates to date of intraspinal anomalies in patients with early onset idiopathic scoliosis, adding to knowledge regarding current incidences of these abnormalities as well as any geographical variation in the nature of the disease.

    2009-01-01

    Idiopathic diaphragm paralysis is probably more common and responsible for more morbidity than generally appreciated. Bell's palsy, or idiopathic paralysis of the seventh cranial nerve, may be seen as an analogous condition. The roles of zoster sine herpete and herpes simplex have increasingly been recognized in Bell's palsy, and there are some data to suggest that antiviral therapy is a useful adjunct to steroid therapy. Thus, we postulated that antiviral therapy might have a positive impact on the course of acute idiopathic diaphragm paralysis which is likely related to viral infection. Three consecutive patients with subacute onset of symptomatic idiopathic hemidiaphragm paralysis were empirically treated with valacyclovir, 1,000 mg twice daily for 1 week. Prior to therapy, diaphragmatic function was assessed via pulmonary function testing and two-dimensional B-mode ultrasound, with testing repeated 1 month later. Diaphragmatic function pre- and post-treatment was compared to that of a historical control group of 16 untreated patients. All three subjects demonstrated ultrasound recovery of diaphragm function 4-6 weeks following treatment with valacyclovir. This recovery was accompanied by improvements in maximum inspiratory pressure (PI(max)) and vital capacity (VC). In contrast, in the untreated cohort, diaphragm recovery occurred in only 11 subjects, taking an average of 14.9 +/- 6.1 months (mean +/- SD). The results of this small, preliminary study suggest that antiviral therapy with valacyclovir may be helpful in the treatment of idiopathic diaphragm paralysis induced by a viral infection.

  9. Role of matrix metalloproteinases in the pathophysiology of idiopathic pulmonary fibrosis

    2007-01-01

    Full Text Available Idiopathic pulmonary fibrosis (IPF, a progressive fibrosing lung condition is a ther-apeutic medical challenge. The etiopathogenesis of IPF is complicated and hitherto not adequately understood. However, the concept, of late, is shifting from fibrosis as a result of inflammation to a mechanism of primarily dysregulated fibrogenesis. A class of enzymes called matrix metallo proteinases (MMPs appear important in the pathogenesis of IPF. The heightened activity of MMPs are derived out of an imbalance between them (MMPs and their tissue inhibitors (TIMPs. This leads to breakdown of interstitial matrix and triggering of certain growth factors which play an important mechanistic role in the pathogenesis of IPF. Understanding of the role of MMPs in pathogenesis of IPF may open up a new horizon of therapeutic intervention of the desease.

  12. [Treatment of chronic idiopathic urticaria unresponsive to type 1 antihistamines in monotherapy].

    Mateus, C

    2003-05-01

    The chronic idiopathic urticaria treatment is a difficult and often frustrating problem for physicians. Due to the lack of definitive medical therapeutic programs to relieve the symptoms and prevent from their recurrence, several pharmacologic approaches to the management of chronic idiopathic urticaria are proposed. The chronic urticaria pharmacologic therapy is therefore fit to abrogate effects of histamine and other mediators on cutaneous vasculature and inflammatory cells that participate in the pathogenesis of the urticaria. The most common approach is to avoid all aggravating factors and to block histamine. The mainstay therapy is the H1 antihistamines. A significant number of patients may remain unresponsive even after an increase in the dose or a change in the type of H1 antihistaminic drug. In these cases, several therapies can be associated: combinations of H1 antihistamines, nonsedating one tablet (morning) and one sedating (evening), this approach is very usual but no study has confirmed it rational; addition an H2 antagonist to the previous treatment for some patients may improve control of their symptoms; alternatively, the tricyclic antidepressant, Doxepin is usually prescribed. The results of other drugs reported in the literature is unpredictable, to include them in a strategy therapy. The results with Badrenergic agents, nifedipine, ketotifen, leukotriene antagonists and tranexamic acid are variable and don't appear better than those with H1 antagonists. The efficiency of danazol has to be confirmed by other controlled studies. Warfarin, sulfasalazine and ultraviolet radiation have been used apparently successfully, but no controlled study has been published. Only when the above treatments have failed then immunosuppresive therapies, intravenous immunoglobulin and plasmapheresis can be proposed for chronic idiopathic urticaria.

    We previously suggested that abnormal sleep behaviors, i.e., as found in parasomnias, may often be the expression of increased activity of the reward system during sleep. Because nightmares and sleepwalking predominate during REM and NREM sleep respectively, we tested here whether exploratory excitability, a waking personality trait reflecting high activity within the mesolimbic dopaminergic (ML-DA) system, may be associated with specific changes in REM and NREM sleep patterns in these two sleep disorders. Twenty-four unmedicated patients with parasomnia (12 with chronic sleepwalking and 12 with idiopathic nightmares) and no psychiatric comorbidities were studied. Each patient spent one night of sleep monitored by polysomnography. The Temperament and Character Inventory (TCI) was administered to all patients and healthy controls from the Geneva population (n = 293). Sleepwalkers were more anxious than patients with idiopathic nightmares (Spielberger Trait anxiety/STAI-T), but the patient groups did not differ on any personality dimension as estimated by the TCI. Compared to controls, parasomnia patients (sleepwalkers together with patients with idiopathic nightmares) scored higher on the Novelty Seeking (NS) TCI scale and in particular on the exploratory excitability/curiosity (NS1) subscale, and lower on the Self-directedness (SD) TCI scale, suggesting a general increase in reward sensitivity and impulsivity. Furthermore, parasomnia patients tended to worry about social separation persistently, as indicated by greater anticipatory worry (HA1) and dependence on social attachment (RD3). Moreover, exploratory excitability (NS1) correlated positively with the severity of parasomnia (i.e., the frequency of self-reported occurrences of nightmares and sleepwalking), and with time spent in REM sleep in patients with nightmares. These results suggest that patients with parasomnia might share common waking personality traits associated to reward-related brain functions

The Temperament and Character Inventory (TCI was administered to all patients and healthy controls from the Geneva population (n = 293.Sleepwalkers were more anxious than patients with idiopathic nightmares (Spielberger Trait anxiety/STAI-T, but the patient groups did not differ on any personality dimension as estimated by the TCI. Compared to controls, parasomnia patients (sleepwalkers together with patients with idiopathic nightmares scored higher on the Novelty Seeking (NS TCI scale and in particular on the exploratory excitability/curiosity (NS1 subscale, and lower on the Self-directedness (SD TCI scale, suggesting a general increase in reward sensitivity and impulsivity. Furthermore, parasomnia patients tended to worry about social separation persistently, as indicated by greater anticipatory worry (HA1 and dependence on social attachment (RD3. Moreover, exploratory excitability (NS1 correlated positively with the severity of parasomnia (i.e., the frequency of self-reported occurrences of nightmares and sleepwalking, and with time spent in REM sleep in patients with nightmares.These results suggest that patients with parasomnia might share common waking personality traits associated to reward-related brain functions

    Idiopathic urethritis [IU] in children is of unknown etiology and treatment options are limited. We propose a classification for IU based on cystourethroscopy findings and symptoms (Grade 1 - 4) and report our experience with use of topical and oral steroids in IU. Retrospective data collection of all male children (0-16 years) diagnosed with IU over a period of 8 years between 2005 and 2012 at our institution. Data was collected on patient demographics, laboratory and radiological investigations, cystourethroscopy findings, management and outcomes. A total of 19 male children were diagnosed with IU. The median age of the patients was 13(7-16) years. Presenting symptoms included dysuria in 12; hematuria in 9; loin pain in 6; and scrotal pain in 2 patients. Both patients with scrotal pain had previous left scrotal exploration that revealed epididymitis. Serum C-reactive protein and Full blood count was tested in 15 patients and was within normal limits in all of them. Cystourethroscopy revealed urethritis of grade-I in 2; grade-II in 11; and grade-III in 3 patients. There were 3 patients with systemic symptoms from extra-urethral extension of inflammation (grade-IV). Mean follow up was 18.9(1-74) months. All patients had steroid instillation at the time of cystourethroscopy. Three patients with IU grade IV required oral steroids (prednisolone) in view of exacerbation of symptoms and signs despite steroid instillation. Complete resolution of symptoms and signs occurred in 18(94.7%) patients. Significant improvement in symptoms and signs was noted in 1(5.3%) patient who is still undergoing treatment. IU in male children can be successfully managed with steroid instillation, especially in grade I and II. Grade III, will need steroid instillation but treatment of scarring and stricture will necessitate longer duration of treatment. In children with IU and extra-urethral symptoms (grade IV), oral steroids may be required.

    Early detection of progressive adolescent idiopathic scoliosis (AIS) was assessed based on 3D quantification of the deformity. Based on 3D quantitative description of scoliosis curves, the aim is to assess a specific phenotype that could be an early detectable severity index for progressive AIS. Early detection of progressive scoliosis is important for adapted treatment to limit progression. However, progression risk assessment is mainly based on the follow up, waiting for signs of rapid progression that generally occur during the growth peak. Sixty-five mild scoliosis (16 boys, 49 girls, Cobb Angle between 10 and 20°) with a Risser between 0 and 2 were followed from their first examination until a decision was made by the clinician, either considering the spine as stable at the end of growth (26 patients) or planning to brace because of progression (39 patients). Calibrated biplanar x-rays were performed and 3D reconstructions of the spine allowed calculating six local parameters related to main curve deformity. For progressive curve 3D phenotype assessment, data were compared with those previously assessed for 30 severe scoliosis (Cobb Angle > 35°), 17 scoliosis before brace (Cobb Angle > 29°) and 53 spines of nonscoliosis subjects. A predictive discriminant analysis was performed to assess similarity of mild scoliosis curves either to those of scoliosis or nonscoliosis spines, yielding a severity index (S-index). S-index value at first examination was compared with clinical outcome. At the first exam, 53 out of 65 predictions (82%) were in agreement with actual clinical outcome. Approximately, 89% of the curves that were predicted as progressive proved accurate. Although still requiring large scale validation, results are promising for early detection of progressive curves. 2.

    To obtain utility estimates suitable for use in economic models for chronic spontaneous (idiopathic) urticaria (CSU). Patient-level data from three randomized clinical trials-ASTERIA I, ASTERIA II and GLACIAL-were analysed. Health states were derived from the Urticaria Activity Score over 7 days (UAS7); higher scores denote greater activity. The health state score ranges were urticaria free: 0; well-controlled urticaria: 1-6; mild urticaria: 7-15; moderate urticaria: 16-27; and severe urticaria: 28-42. The mean EQ-5D utilities were calculated for each health state. A mixed model was used to predict the EQ-5D according to UAS7 health states in a pooled data set containing all treatment arms and time points from the three trials. Pooled trial data were validated through visual comparisons and interaction terms. Fixed and random effects for trials and patients were included, along with the following covariates: UAS7 health state at baseline (moderate or severe); presence of angioedema at baseline and during follow-up; duration of CSU; number of previous CSU medications; visit; current treatment; and patient age and sex. There was a consistent improvement in EQ-5D utilities as urticaria activity decreased. The mean utilities ranged from 0.710 (severe urticaria) to 0.780 (moderate urticaria), 0.829 (mild urticaria), 0.862 (well-controlled urticaria) and 0.894 (urticaria free). Sensitivity and subgroup analyses confirmed the robustness of the results. The results suggest that EQ-5D utility scores increase with decreasing urticaria activity. EQ-5D utility scores enable the health-related quality of life of CSU patients to be compared with that of patients with other diseases.

    2017-01-01

    Abstract Background and objective: Glucocorticoids are the standard treatment for idiopathic sudden sensorineural hearing loss (ISSNHL), but whether intratympanic or systemic therapy is superior remains controversial. Previous meta-analyses of this question have omitted key clinical trials or included observational studies. Methods: English-language randomized controlled trials in OvidSP, PubMed, Embase, CINAHL, and the Cochrane Library comparing intratympanic versus systemic glucocorticoid therapy for ISSNHL were meta-analyzed using RevMan 5.3. The primary outcome of interest was improvement in pure tone average (PTA) threshold. Results: Six trials involving 248 patients receiving intratympanic steroids and 236 receiving systemic steroids were meta-analyzed. PTA thresholds were similar between the 2 groups at 3 months after therapy initiation (mean difference, 0.24; 95% confidence interval [CI] −2.43 to 2.91, P = .86; I2 = 54%, P = .07, random-effects model). PTA thresholds were also similar at 6 months (mean difference, 4.69, 95% CI −5.84 to 15.22, P = .38), although the results showed extremely high heterogeneity (I2 = 98%). Sensitivity analysis indicated that a single trial containing 250 patients provided the strongest evidence for equivalence between the 2 types of therapy. Rates of recovery within 3 months (defined as PTA improvement >10 dB) were similar between the 2 types of therapy (odds ratio 0.92, 95% CI 0.59–1.43, P = .70), with no significant heterogeneity in the pooled data (I2 = 1%, P = .40). Conclusion: Intratympanic and systemic steroids’ therapies appear to show similar short-term efficacy for restoring hearing in patients with ISSNHL. Intratympanic therapy may reduce systemic side effects associated with steroid use. PMID:29390288

  1. A study of idiopathic generalised epilepsy in an Irish population.

    2012-02-03

    Idiopathic generalised epilepsy (IGE) is subdivided into syndromes based on clinical and EEG features. PURPOSE: The aim of this study was to characterise all cases of IGE with supportive EEG abnormalities in terms of gender differences, seizure types reported, IGE syndromes, family history of epilepsy and EEG findings. We also calculated the limited duration prevalence of IGE in our cohort. METHODS: Data on abnormal EEGs were collected retrospectively from two EEG databases at two tertiary referral centres for neurology. Clinical information was obtained from EEG request forms, standardised EEG questionnaires and medical notes of patients. RESULTS: two hundred twenty-three patients met our inclusion criteria, 89 (39.9%) male and 134 (60.1%) females. Tonic clonic seizures were the most common seizure type reported, 162 (72.65%) having a generalised tonic clonic seizure (GTCS) at some time. IGE with GTCS only (EGTCSA) was the most common syndrome in our cohort being present in 94 patients (34 male, 60 female), with 42 (15 male, 27 female) patients diagnosed with Juvenile myoclonic epilepsy (JME), 23 (9 male, 14 female) with Juvenile absence epilepsy (JAE) and 20 (9 male, 11 female) with childhood absence epilepsy (CAE). EEG studies in all patients showed generalised epileptiform activity. CONCLUSIONS: More women than men were diagnosed with generalised epilepsy. Tonic clonic seizures were the most common seizure type reported. EGTCSA was the most frequent syndrome seen. Gender differences were evident for JAE and JME as previously reported and for EGTCSA, which was not reported to date, and reached statistical significance for EGTCA and JME.

    2015-11-01

    A total of 109 recordings aiming to identify Bryde's whale calls were collected from the Gulf of California, Mexico, during field trips performed from January 2010 to June 2014. Vocalizations were recorded only when no calves were observed. Four types of calls were identified. Calls similar to the Be4 call type previously reported for the Eastern Tropical Pacific region and South of California were recorded. In addition, three calls, not reported in previous studies of the Bryde's whale, have also been identified. The identification of these calls, which were labeled Be10, Be11, and Be12, enables expansion of the known acoustic repertoire of this species, which is currently poorly documented. The identification of three previously unreported calls and the confidence given by careful visual confirmation of the whale species and number of individuals contribute to make this study a significant contribution toward the acoustic monitoring of Bryde's whale.

    A Swedish pedigree with an autosomal dominant inheritance of idiopathic scoliosis was initially studied by genetic linkage analysis, prioritising genomic regions for further analysis. This revealed a locus on chromosome 1 with a putative risk haplotype shared by all affected individuals. Two......, but showed reduced penetrance. Analysis of tagging variants in CELSR1-3 in a set of 1739 Swedish-Danish scoliosis cases and 1812 controls revealed significant association (p = 0.0001) to rs2281894, a common synonymous variant in CELSR2. This association was not replicated in case-control cohorts from Japan...... and the US. No association was found to variants in CELSR1 or CELSR3. Our findings suggest a rare variant in CELSR2 as causative for idiopathic scoliosis in a family with dominant segregation and further highlight common variation in CELSR2 in general susceptibility to idiopathic scoliosis in the Swedish...

  12. Idiopathic intracranial hypertension without papilledema in children: A case series

    Directory of Open Access Journals (Sweden)

    Kaliopy Matheos

    2015-05-01

    Full Text Available Papilledema has long been considered a hallmark of idiopathic intracranial hypertension, a disease defined by elevated intracranial pressure with indiscernible etiology. Papilledema is often seen in the pediatric population, and as such can lead to delays in diagnosis, and often misdiagnosis. Here, we describe three children who were confirmed to have idiopathic intracranial hypertension with raised intracranial pressure by repeated lumbar puncture or intracranial pressure monitoring, normal neuroimaging and absence of papilledema. All three cases had atypical clinical presentations with visual disturbances or photophobia. The patients had a normal body mass index. This case series demonstrates that idiopathic intracranial hypertension can manifest in the absence of clinically obvious papilledema, and has, as such, the potential to cause permanent visual loss if the diagnosis is missed.

    Helicobacter pylori infection-negative, nonsteroidal antiinflammatory drugs (NSAIDs)-negative peptic ulcers, which are termed idiopathic peptic ulcers (IPUs), have been increasing worldwide. In this study, we investigated the preferential locations of gastric ulcers according to their cause (e.g., H. pylori and NSAIDs), with special attention to IPUs. A total of 361 patients consecutively diagnosed with a peptic ulcer over a period of one year were classified into four groups according to H. pylori-infection status and NSAIDs usage. The ulcer location was divided into the antrum, angularis, and body, and was compared among the four ulcer groups. The ulcers of 43 patients were classified as IPUs. Compared with simple H. pylori ulcers, IPUs more preferentially located in the antrum (14% vs. 52%, p < 0.01). The difference was more pronounced in the analysis of IPUs in which patients with a history of H. pylori eradication or those with severe atrophic gastritis were excluded, and 79% of these IPUs were located in the antrum. With duodenal ulcers taken together, the vast majority of (86%) these IPUs occurred in the duodenal bulb or the antrum. The proportion of antral ulcers in NSAISs users also differed depending on the presence of concomitant H. pylori infection (positive: 22% vs. negative: 62%, p < 0.01). There was a striking difference in the ulcer location within the stomach depending on the cause of the ulcer, and IPUs predominantly occurred in the antrum. This information on the preferential locations of ulceration should provide endoscopists with some hints concerning the etiology of ulcers.

    The cervical spine in Chiari I patient with syringomyelia has significantly different anteroposterior diameters than it does in Chiari I patients without syringomyelia. We tested the hypothesis that patients with idiopathic syringomyelia (IS) also have abnormal cervical spinal canal diameters. The finding in both groups may relate to the pathogenesis of syringomyelia. Local institutional review boards approved this retrospective study. Patients with IS were compared to age-matched controls with normal sagittal spine MR. All subjects had T1-weighted spin-echo (500/20) and T2-weighted fast spin-echo (2000/90) sagittal cervical spine images at 1.5 T. Readers blinded to demographic data and study hypothesis measured anteroposterior diameters at each cervical level. The spinal canal diameters were compared with a Mann-Whitney U test. The overall difference was assessed with a Friedman test. Seventeen subjects were read by two reviewers to assess inter-rater reliability. Fifty IS patients with 50 age-matched controls were studied. IS subjects had one or more syrinxes varying from 1 to 19 spinal segments. Spinal canal diameters narrowed from C1 to C3 and then enlarged from C5 to C7 in both groups. Diameters from C2 to C4 were narrower in the IS group (p < 0.005) than in controls. The ratio of the C3 to the C7 diameters was also smaller (p = 0.004) in IS than controls. Collectively, the spinal canal diameters in the IS were significantly different from controls (Friedman test p < 0.0001). Patients with IS have abnormally narrow upper and mid cervical spinal canal diameters and greater positive tapering between C3 and C7. (orig.)

    Idiopathic hypertrophic pyloric stenosis (IHPS) is one of the most common causes of persistent nonbilous vomiting in early infancy. The authors retrospectively studied 123 patients with nonbilous vomiting and analyzed the ultrasonographic findings of 51 cases of surgically proven IHPS. No false negative or false positive cases by ultrasonography were confirmed by follow-up clinical observation. US was performed with real-time scanners equipped with a 5MHz transducer (Acuson 128) and a 10MHz transducer (Spectra, Diasonic). All symptomatic infants were first screened in as supine position to determine the amount of gastric retention. The pylorus was imaged most often with the infants in the right decubitus 30-degree position. To improve imaging of the pylorus, if necessary, the infants were fed E-solution (60-100cc) and then examined. The average sonographic measurements of pyloric muscle thickness (MT), pyloric diameter (PD), and pyloric canal length (PL) were 5.46mm (range 3.6-7.9mm), 15.4mm (range 12.0-18.3mm), and 22.58mm, (range 18.0-29.9mm). The ratio of pyloric muscle thickness to the pylorus (MT/PD) was 0.36 (range 0.22-0.55). With these measurements, the authors considered the hypertrophic pyloric muscle and the elongated pylorus as a cylinder, and so the pyloric volume was calculated. The pyloric volume (PV), which was equated to 1/4 {pi} xPD{sup 2}xPL, was 4.24mL (range 2.62-6.36mL). It was concluded that high-resolution, real-time sonography is a simple and accurate method for the diagnosis of IHPS and should be the initial imaging modality.

  16. Recent advances in understanding idiopathic pulmonary fibrosis

    2016-01-01

    Despite major research efforts leading to the recent approval of pirfenidone and nintedanib, the dismal prognosis of idiopathic pulmonary fibrosis (IPF) remains unchanged. The elaboration of international diagnostic criteria and disease stratification models based on clinical, physiological, radiological, and histopathological features has improved the accuracy of IPF diagnosis and prediction of mortality risk. Nevertheless, given the marked heterogeneity in clinical phenotype and the considerable overlap of IPF with other fibrotic interstitial lung diseases (ILDs), about 10% of cases of pulmonary fibrosis remain unclassifiable. Moreover, currently available tools fail to detect early IPF, predict the highly variable course of the disease, and assess response to antifibrotic drugs. Recent advances in understanding the multiple interrelated pathogenic pathways underlying IPF have identified various molecular phenotypes resulting from complex interactions among genetic, epigenetic, transcriptional, post-transcriptional, metabolic, and environmental factors. These different disease endotypes appear to confer variable susceptibility to the condition, differing risks of rapid progression, and, possibly, altered responses to therapy. The development and validation of diagnostic and prognostic biomarkers are necessary to enable a more precise and earlier diagnosis of IPF and to improve prediction of future disease behaviour. The availability of approved antifibrotic therapies together with potential new drugs currently under evaluation also highlights the need for biomarkers able to predict and assess treatment responsiveness, thereby allowing individualised treatment based on risk of progression and drug response. This approach of disease stratification and personalised medicine is already used in the routine management of many cancers and provides a potential road map for guiding clinical care in IPF.

    2014-01-01

    Objectives: The aim of this study was to determine the prevalence of idiopathic normal-pressure hydrocephalus (iNPH) in elderly persons in a large population-based sample using radiologic and clinical examinations. Methods: We examined representative elderly populations aged 70 years and older that had undergone neuropsychiatric evaluations and CT of the brain between 1986 and 2000 (n = 1,238). Gait was evaluated by clinical examination and history of walking difficulty. Cognitive function was evaluated with the Mini-Mental State Examination and urinary incontinence by self-report. iNPH was diagnosed in concordance with the American-European iNPH guidelines. Exclusion criteria were history of meningitis, severe head trauma, and subarachnoid hemorrhage. Results: The prevalence of probable iNPH was 0.2% in those aged 70–79 years (n = 2) and 5.9% (n = 24) in those aged 80 years and older, with no difference between men and women. Only 2 of these persons had been treated for iNPH. Hydrocephalic ventricular enlargement, i.e., a CT image consistent with NPH, was found in 56 persons (4.5%). An Evans Index >0.3 was found in 256 (20.7%) and occluded sulci at the high convexity in 67 persons (5.4%). All of these findings were more common in the older age groups. Conclusions: Many elderly possess clinical and imaging features of iNPH, especially those older than 80 years. The number of persons with iNPH is probably much higher than the number of persons currently treated. PMID:24682964

    Full Text Available Diffuse idiopathic skeletal hyperosteosis (DISH, also known as Forestier disease, is an idiopathic chronic disorder characterized by the calcification of the anterior longitudinal ligament of the vertebral column and various extraspinal ligaments. It is usually asymptomatic but the most common symptoms are spinal pain, limited range of spinal motion and dysphagia. Spinal canal stenosis and myelopathia may rarely be seen. We present with the relevant literature a 64-year-old male who developed paraplegia due to thoracal spinal stenosis on a background of DISH.

    Idiopathic intracranial hypertension is a disorder of unknown pathogenesis. Natriuretic peptides may be involved in intracranial pressure regulation, but cerebrospinal fluid (CNS) and plasma concentrations in this disorder are unknown. We evaluated venous and intrathecal concentrations of ANP, BNP...... and CNP precursor peptides in 40 patients with idiopathic intracranial hypertension and in 20 controls. Natriuretic pro-peptides were quantitated using processing-independent assays.

    To determine the frequency of tests done in the year before elective surgery that might substitute for preoperative screening tests and to determine the frequency of test results that change from a normal value to a value likely to alter perioperative management. Retrospective cohort analysis of computerized laboratory data (complete blood count, sodium, potassium, and creatinine levels, prothrombin time, and partial thromboplastin time). Urban tertiary care Veterans Affairs Hospital. Consecutive sample of 1109 patients who had elective surgery in 1988. At admission, 7549 preoperative tests were done, 47% of which duplicated tests performed in the previous year. Of 3096 previous results that were normal as defined by hospital reference range and done closest to the time of but before admission (median interval, 2 months), 13 (0.4%; 95% CI, 0.2% to 0.7%), repeat values were outside a range considered acceptable for surgery. Most of the abnormalities were predictable from the patient's history, and most were not noted in the medical record. Of 461 previous tests that were abnormal, 78 (17%; CI, 13% to 20%) repeat values at admission were outside a range considered acceptable for surgery (P less than 0.001, frequency of clinically important abnormalities of patients with normal previous results with those with abnormal previous results). Physicians evaluating patients preoperatively could safely substitute the previous test results analyzed in this study for preoperative screening tests if the previous tests are normal and no obvious indication for retesting is present.

    Bat echolocation is primarily used for orientation and foraging but also holds great potential for social communication. The communicative function of echolocation calls is still largely unstudied, especially in the wild. Eavesdropping on vocal signatures encoding social information in echolocation calls has not, to our knowledge, been studied in free-living bats so far. We analysed echolocation calls of the polygynous bat Saccopteryx bilineata and found pronounced vocal signatures encoding sex and individual identity. We showed experimentally that free-living males discriminate approaching male and female conspecifics solely based on their echolocation calls. Males always produced aggressive vocalizations when hearing male echolocation calls and courtship vocalizations when hearing female echolocation calls; hence, they responded with complex social vocalizations in the appropriate social context. Our study demonstrates that social information encoded in bat echolocation calls plays a crucial and hitherto underestimated role for eavesdropping conspecifics and thus facilitates social communication in a highly mobile nocturnal mammal.

  2. Mother goats do not forget their kids’ calls

    Parent–offspring recognition is crucial for offspring survival. At long distances, this recognition is mainly based on vocalizations. Because of maturation-related changes to the structure of vocalizations, parents have to learn successive call versions produced by their offspring throughout ontogeny in order to maintain recognition. However, because of the difficulties involved in following the same individuals over years, it is not clear how long this vocal memory persists. Here, we investigated long-term vocal recognition in goats. We tested responses of mothers to their kids’ calls 7–13 months after weaning. We then compared mothers’ responses to calls of their previous kids with their responses to the same calls at five weeks postpartum. Subjects tended to respond more to their own kids at five weeks postpartum than 11–17 months later, but displayed stronger responses to their previous kids than to familiar kids from other females. Acoustic analyses showed that it is unlikely that mothers were responding to their previous kids simply because they confounded them with the new kids they were currently nursing. Therefore, our results provide evidence for strong, long-term vocal memory capacity in goats. The persistence of offspring vocal recognition beyond weaning could have important roles in kin social relationships and inbreeding avoidance. PMID:22719031

  4. Responses of squirrel monkeys to their experimentally modified mobbing calls

    2003-05-01

    Previous acoustic analyses suggested emotion-correlated changes in the acoustic structure of squirrel monkey (Saimiri sciureus) vocalizations. Specifically, calls given in aversive contexts were characterized by an upward shift in frequencies, often accompanied by an increase in amplitude. In order to test whether changes in frequencies or amplitude are indeed relevant for conspecific listeners, playback experiments were conducted in which either frequencies or amplitude of mobbing calls were modified. Latency and first orienting response were measured in playback experiments with six adult squirrel monkeys. After broadcasting yaps with increased frequencies or amplitude, squirrel monkeys showed a longer orienting response towards the speaker than after the corresponding control stimuli. Furthermore, after broadcasting yaps with decreased frequencies or amplitude, squirrel monkeys showed a shorter orienting response towards the speaker than after the corresponding manipulated calls with higher frequencies or amplitude. These results suggest that changes in frequencies or amplitude were perceived by squirrel monkeys, indicating that the relationship between call structure and the underlying affective state of the caller agreed with the listener's assessment of the calls. However, a simultaneous increase in frequencies and amplitude did not lead to an enhanced response, compared to each single parameter. Thus, from the receiver's perspective, both call parameters may mutually replace each other.

    Since 2014, OnabotulinumtoxinA Botox ® (Allergan, Inc., Irvine, USA) represents a new therapeutic option for second-line treatment of idiopathic overactive bladder. The purpose of the current study was to evaluate practices of surgeons using onabotulinium toxin (BoNTA) in this indication. All urogynecology centers of the country were asked in order to list all patients who were treated since marketing autorisation. Patient symptoms, previous treatments, paraclinic evaluations, data of surgery and the characteristics of the follow up were collected and analyzed. Six centers used BoNTA and five have accepted to participate. Ninety-seven patients have been identified. Sixty-eight first injections (70 %) were carried out with the strict frameworf of the marketing autorisation (urinary frequency, urinary urgency, urinary incontinence). All patients had at least two symptoms. In 69 %, Botulinum toxin was a second-line treatment after the failure of tibial neuromodulation or sacral neuromodulation. Urodynamic evaluation was carried out for 91 % of patients. The search for a post-void residual volume was observed for 59 % of patients during the follow up. In our country, BoNTA injections for idiopathic overactive bladder are mainly effected after tibial neuromodulation or sacral neuromodulation failure. Diagnostic, operating and outcome evaluation practices are still very heterogeneous pleading for a greater standardization of this new therapy in this indication. 3.

    This paper is a case presentation of a idiopathic cerebral calcification manifesting itself as a Parkinsonism. The patient, a 48-year-old female, was admitted to this hospital with a chief complaint of gait disturbance that had developed over the previous four months. On admission she was noted to have a slight dimunition of her mental capacity, a rigidity of her extremities (more pronounced in the lower limbs), and akinesia, though no tremor. CT scans revealed extensive areas of calcification in the central nervous system, encompassing the cerebral basal ganglia (corpus striatum), the cerebellum, the midbrain, and the gray and white matter of the cerebrum. There was no evidence of calcification in the spinal cord. Physical and laboratory examinations did not yield any findings suggestive of abnormalities in calcium metabolism, nor was there any indication that her condition was of a familial nature. The case was concluded, therefore, to be idiopathic. Amelioration in the symptoms occurred following the administration of L-dopa. (author)

    Idiopathic thrombotic thrombocytopenic purpura (TTP) patients have ADAMTS13 deficiency, which is usually caused by ADAMTS13 autoantibodies. However, the triggering factors for the autoantibody production remain unclear. Interferon-α (IFN-α) is a cytokine involved with many autoimmune processes such as inducing the activation of peripheral dendritic cells and stimulating T cells and B cells. It also plays an important role in some autoimmune diseases. Elevated IFN-α levels have been observed in some TTP patients and previous case reports have shown the occurrence of TTP after IFN-α treatment. Thus, we hypothesized that high levels of IFN-α would correlate with presence of ADAMTS13 autoantibodies. However, we did not observe elevated IFN-α levels in 36 TTP patients (mean 5.29 pg/ml, standard deviation (SD) 26.56 pg/ml) compared to healthy controls (mean 0 pg/ml, SD 0 pg/ml), P = 0.59. IFN-α levels of most patients (94%) were undetectable. Only two patients had increased IFN-α levels and ADAMTS13 autoantibodies were detected in these two patients. Interestingly, both the patients had an underlying autoimmune disease. Although there have been cases of secondary TTP following IFN-α treatment, no evidence supports a role of IFN-α in the development of idiopathic TTP in our patient population. © 2014 Wiley Periodicals, Inc.

  8. How 'idiopathic' is adolescent idiopathic scoliosis? A systematic review on associated abnormalities.

    Directory of Open Access Journals (Sweden)

    Tom P C Schlösser

    Full Text Available BACKGROUND: Despite more than a century of dedicated research, the etiology and pathogenesis of adolescent idiopathic scoliosis (AIS remain unclear. By definition, 'idiopathic' implies an unknown cause. Nevertheless, many abnormalities concomitant to AIS have been described, often with the suggestion that these abnormalities are related to etio-pathogenesis. Insight in the concomitant abnormalities may assist in improving the understanding of the etiological pathways of AIS. We aimed to systematically review and synthesize available studies on abnormalities concomitant to AIS. METHODS: Original studies comparing untreated AIS patients with healthy adolescents on abnormalities other than the deformity of the spine were retrieved from PubMed and Embase. We followed PRISMA guidelines and to quantify the relationship between each abnormality and AIS we used a best-evidence-syntheses for relating risk-of-bias to consistency of effect sizes. RESULTS: We identified 88 relevant citations, forty-seven carried high risk-of-bias and twenty studies did not report quantitative data in a sufficient manner. The remaining twenty-one publications failed to report data from before initiation of the deformity and blind assessments. These cross-sectional studies provided data on fourteen abnormalities concomitant to AIS. With our best-evidence-syntheses we were unable to find both strong evidence and a consistent pattern of occurrence for AIS and any of these abnormalities. From moderate risk-of-bias studies a relatively consistent pattern of occurrence for AIS and impaired gait control (4 studies; 155 subjects; Cohen's d = 1.00 and decreased bone mineral density (2 studies; 954 subjects; Cohen's d = -0.83 was found. For nine abnormalities a consistent pattern of occurrence with AIS was found, but the evidence for these was weak. CONCLUSIONS: Based on the available literature, strong evidence is lacking for a consistent pattern of occurrence of AIS and any

    Urinary excretion of alpha-1-microglobulin and beta-2-microglobulin reflects tubular damage and predicts outcome in patients with idiopathic membranous nephropathy with reasonable accuracy. Urinary kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin are novel biomarkers of tubular damage. We investigated if these markers could improve prediction of outcome in idiopathic membranous nephropathy. We measured kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin in urine samples from patients with idiopathic membranous nephropathy, who had nephrotic proteinuria and normal renal function. Excretion of alpha-1-microglobulin and beta-2-microglobulin had been measured previously. Progression was defined as a serum creatinine rise >30%, a rise in serum creatinine to an absolute value of ≥135 µmol/L, or a clinical decision to start immunosuppressive therapy. Remission was defined as proteinuria 50% reduction from baseline. Sixty-nine patients were included. Median follow-up was 35 months (interquartile range 18-63 months). Progression occurred in 30 patients (44%), and spontaneous remission in 36 (52%). Kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin excretion rates were significantly correlated with each other, and with alpha-1-microglobulin and beta-2-microglobulin. The areas under the receiver operating characteristic curves for progression were 0.75 (0.62-0.87) for kidney injury molecule-1 and 0.74 (0.62-0.87) for neutrophil gelatinase-associated lipocalin. In multivariate analysis with either alpha-1-microglobulin and beta-2-microglobulin, kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin did not independently predict outcome. Kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin excretion rates correlated with excretion rates of other tubular damage markers and predicted outcome in patients with idiopathic membranous nephropathy. They did not add prognostic value

    Background and purpose - Patients with osteoporosis who present with an acute onset of back pain often have multiple fractures on plain radiographs. Differentiation of an acute osteoporotic vertebral fracture (AOVF) from previous fractures is difficult. The aim of this study was to investigate the incidence of concomitant AOVFs and previous OVFs in patients with symptomatic AOVFs, and to identify risk factors for concomitant AOVFs. Patients and methods - This was a prospective epidemiological study based on the Registry of Pathological Osteoporotic Vertebral Fractures (REPAPORA) with 1,005 patients and 2,874 osteoporotic vertebral fractures, which has been running since February 1, 2006. Concomitant fractures are defined as at least 2 acute short-tau inversion recovery (STIR-) positive vertebral fractures that happen concomitantly. A previous fracture is a STIR-negative fracture at the time of initial diagnostics. Logistic regression was used to examine the influence of various variables on the incidence of concomitant fractures. Results - More than 99% of osteoporotic vertebral fractures occurred in the thoracic and lumbar spine. The incidence of concomitant fractures at the time of first patient contact was 26% and that of previous fractures was 60%. The odds ratio (OR) for concomitant fractures decreased with a higher number of previous fractures (OR =0.86; p = 0.03) and higher dual-energy X-ray absorptiometry T-score (OR =0.72; p = 0.003). Interpretation - Concomitant and previous osteoporotic vertebral fractures are common. Risk factors for concomitant fractures are a low T-score and a low number of previous vertebral fractures in cases of osteoporotic vertebral fracture. An MRI scan of the the complete thoracic and lumbar spine with STIR sequence reduces the risk of under-diagnosis and under-treatment.

    Full Text Available The management of idiopathic nephrotic syndrome (INS in children includes immunosuppressive and symptomatic treatment. The response to corticosteroid therapy is the best prognostic marker of the disease. The majority of children with INS (about 85% are steroid-sensitive as they normalize proteinuria within 4 weeks of daily, oral prednisone administration. The most of steroid-sensitive patients (94% has minimal change of nephrotic syndrome, while the majority (80.5%-94.4% of those who are steroid-resistant has focal segmental glomerulosderosis or mesangioproliferative glomerulonephritis. Initial therapy of INS consists of 60 mg/m2/day prednisone daily for 4 weeks followed by 40 mg/m2 on alternate days for 4 weeks, thereafter decreasing alternate day therapy every month by 25% over the next 4 months. Thus, the overall duration of the initial cortico-steroids course is 6 months that may be significantly protective against the future development of frequent relapses. Approximately 30% of patients experience only one attack and are cured after the first course of therapy; 10-20% have only 3 or 4 steroid-responsive episodes before permanent cure; the remaining 40-50% of patients are frequent relapsers, or steroid-dependent. Standard relapse therapy consists of 60 mg/m2/ day prednisone until urine is protein free for at least 3 days, followed by 40 mg/m2 on alternate days for 4 weeks. The treatment of frequent-relapses and steroid-dependent INS includes several different regimens: maintenance (6 months alternate steroid therapy just above steroid threshold (0.1-0.5 mg/kg/ 48h, levamisole, alkylating agents (cyclophosphamide or chlorambucil or cyclosporine. The worse prognosis is expected in steroid-resistant patients who are the most difficult to treat. Renal biopsy should be performed in them. At present, there is no consensus on therapeutic regimen for steroid-resistant patients. The following immunosuppressive drugs have been used with varying

    Trunk imbalance (ie, frontal trunk shift measured with a plumb line from C7 to S1) is part of the clinical evaluation in adolescent idiopathic scoliosis (AIS), but its prevalence and relationship with scoliosis, back pain, and health-related factors are not well documented. The principal objectives are to document trunk imbalance prevalence and to explore the association between trunk imbalance and the following factors: Cobb angle, type of scoliosis, back pain, function, mental health, and self-image. The secondary objective is to determine back pain prevalence and the relationship between back pain and each of the following: Cobb angle, function, mental health, and self-image. This is a cross-sectional study in a scoliosis clinic of a tertiary university hospital center. The sample includes youth with AIS (N=55). The outcome measures were trunk imbalance prevalence and magnitude, and back pain prevalence and intensity using the Numeric Pain Rating Scale (NPRS) and the Scoliosis Research Society-22 (SRS-22) pain score, and the function, self-image, and mental health domains of the SRS-22. Trunk imbalance and back pain were assessed in 55 patients with AIS (Cobb angle: 10-60°). Patients completed the SRS-22 questionnaire and the NPRS. Correlations were done between trunk imbalance and scoliosis (Cobb angle, type of scoliosis), back pain (NPRS and SRS-22 pain score), and health-related factors using Pearson correlation coefficients (r) and logistic regression models. Trunk imbalance prevalence is 85% and back pain prevalence is 73%. We found fair to moderate significant positive correlation between trunk imbalance and Cobb angle (r=0.32-0.66, pself-image, or type of scoliosis. Lower self-reported pain significantly correlated with lower Cobb angles (r=0.29, p=.03), higher function (r=0.55, p=.000), higher self-image (r=0.44, p=.001), and better mental health (r=0.48, p=.000). There was a trend for trunk imbalance to be related with lower pain in logistic regression

    Full Text Available Haifa A Madi,1,* Ibrahim Masri,1,* David H Steel1,2 1Sunderland Eye Infirmary, Sunderland, 2Institute of Genetic Medicine, Newcastle University, International Centre for Life, Newcastle, UK *These authors contributed equally to this work Abstract: This review evaluates the current surgical options for the management of idiopathic macular holes (IMHs, including vitrectomy, ocriplasmin (OCP, and expansile gas use, and discusses key background information to inform the choice of treatment. An evidence-based approach to selecting the best treatment option for the individual patient based on IMH characteristics and patient-specific factors is suggested. For holes without vitreomacular attachment (VMA, vitrectomy is the only option with three key surgical variables: whether to peel the inner limiting membrane (ILM, the type of tamponade agent to be used, and the requirement for postoperative face-down posturing. There is a general consensus that ILM peeling improves primary anatomical hole closure rate; however, in small holes (<250 µm, it is uncertain whether peeling is always required. It has been increasingly recognized that long-acting gas and face-down positioning are not always necessary in patients with small- and medium-sized holes, but large (>400 µm and chronic holes (>1-year history are usually treated with long-acting gas and posturing. Several studies on posturing and gas choice were carried out in combination with ILM peeling, which may also influence the gas and posturing requirement. Combined phacovitrectomy appears to offer more rapid visual recovery without affecting the long-term outcomes of vitrectomy for IMH. OCP is licensed for use in patients with small- or medium-sized holes and VMA. A greater success rate in using OCP has been reported in smaller holes, but further predictive factors for its success are needed to refine its use. It is important to counsel patients realistically regarding the rates of success with

It has been proposed that these copulation calls function to incite males to compete for access to the calling female. Two separate advantages of inciting male-male competition in this way have been put forward. The first suggests that as a result of calling, females are only mated by the highest ranking male in the vicinity (indirect mate choice hypothesis). The second proposes that copulation cal...

    No ideal therapeutic method currently exists for refractory idiopathic supraorbital neuralgia patients who don't respond to conservative therapy, including medications and nerve blocks. Pulsed radiofrequency is a neuromodulation technique that does not produce sequelae of nerve damage after treatment. However, the efficacy of percutaneous pulsed radiofrequency for the treatment of refractory idiopathic supraorbital neuralgia is still not clear. The purpose of our study was to evaluate the efficacy and safety of pulsed radiofrequency treatment of the supraorbital nerve for refractory supraorbital neuralgia patients. We prospectively investigated the long-term effects of ultrasound-guided percutaneous pulsed radiofrequency in the treatment of 22 refractory idiopathic supraorbital neuralgia patients. A reduction of verbal pain numerical rating scale score of more than 50% was used as the standard of effectiveness. The effectiveness rates at different time points within two years were calculated. After a single pulsed radiofrequency treatment, the effectiveness rate at one and three months was 77%, and the rates at six months, one year, and two years were 73%, 64%, and 50%, respectively. Except for a small portion of patients (23%) who experienced mild upper eyelid ecchymosis that gradually disappeared after approximately two weeks, no obvious complications were observed. In conclusion, the results of our study demonstrate that for patients with refractory idiopathic supraorbital neuralgia, percutaneous pulsed radiofrequency may be an effective and safe treatment choice.

    Objectives: Patients with idiopathic pulmonary fibrosis (IPF) have an increased risk of pulmonary tuberculosis. However, detecting pulmonary tuberculosis may be difficult due to the underlying fibrosis. The aim of this report is to describe the radiological and clinical findings of pulmonary tuberculosis in patients with idiopathic pulmonary fibrosis. Materials and methods: We reviewed 143 consecutive patients in whom IPF was diagnosed by either the histological or radio-clinical criteria. Among them, nine patients were histologically (n=2) or bacteriologically (n=7) confirmed to have active pulmonary tuberculosis. The location and patterns of pulmonary tuberculosis were examined on a thin section CT scan. Results: The most common thin section CT findings were subpleural nodules (n=6; mean diameter, 3.2 cm) and a lobar or segmental consolidation (n=3). The lesions were located most commonly in the right lower lobe (n=4). The incidence of tuberculosis in patients with idiopathic pulmonary fibrosis was more than five times higher than that of the general population. Conclusion: The atypical manifestation of pulmonary tuberculosis is common in patients with idiopathic pulmonary fibrosis, which may mimic lung cancer or bacterial pneumonia.

    To present the rare case of a young boy with idiopathic intracranial hypertension presenting with bilateral sensorineural hearing loss developing over several months. This was accompanied by headaches, otalgia, tinnitus, and vertigo. Furthermore, we aim to provide a concise review on this matter, as this report represents the second case in literature of pediatric idiopathic intracranial hypertension presenting with hearing loss. Workup of a 9-year-old boy with bilateral sensorineural hearing loss, including (among others) physical examination, audiometry, diagnostic imaging, and lumbar puncture. Physical examination including fundoscopy as well as imaging showed no abnormalities. At presentation, pure tone audiometry revealed bone conduction thresholds of about 30 dB HL in both ears. Two months later, this declined to about 35 dB HL in both ears. Lumbar puncture revealed an increased intracranial pressure. The boy was thus diagnosed with idiopathic intracranial hypertension. After the lumbar puncture, the otological complaints gradually resolved, and the hearing normalized (bone conduction thresholds of 0-5 dB HL). Although rare, sensorineural hearing loss in the pediatric population together with otalgia, tinnitus, and vertigo can be due to idiopathic intracranial hypertension and as such can be reversible. © The Author(s) 2015.

    Oral anticoagulant therapy for more than 6 months in patients with an episode of idiopathic thromboembolic disease is controversial. The objective was to determine predictive clinical signs that identify patients at increased risk of thromboembolic recurrence after stopping anticoagulant therapy for 6 months after an episode of idiopathic deep vein thrombosis (DVT). A prospective study which included 306 consecutive patients with a first episode of idiopathic DVT from June 2012 to June 2014. Predictor variables of recurrent thromboembolic disease and episodes of recurrence during follow-up of the patients (28.42 months) were collected. We performed a multivariate analysis to analyze possible predictors (P<.20) and an analysis of Kaplan-Meier to establish mean recurrence-free survival. We identified 91 episodes of residual vein thrombosis on follow-up of the patients (37.5% men and 20.3% women) (OR 1.84; 95% CI 1.25-2.71). In the Cox regression analysis stratified by gender, variables showed significant presence of hyperechoic thrombus (P=.001) in males, and persistence of residual thrombus in women (P=.046). The mean recurrence-free survival was shorter in both groups. The presence of echogenic thrombus in men and the existence of residual DVT in women were 2 clinical signs associated with increased risk of thromboembolic recurrence after stopping anticoagulant therapy for 6 months after an episode of idiopathic DVT in our study.

    Théroux, Jean; Stomski, Norman; Losco, Christine Dominique; Khadra, Christelle; Labelle, Hubert; Le May, Sylvie

    The purpose of this study was to perform a systematic review of clinical trials of spinal manipulative therapy for adolescent idiopathic scoliosis. Search strategies were developed for PubMed, CINHAL, and CENTRAL databases. Studies were included through June 2016 if they were prospective trials that evaluated spinal manipulative therapy (eg, chiropractic, osteopathic, physical therapy) for adolescent idiopathic scoliosis. Data were extracted and assessed by 2 independent reviewers. Cochrane risk of bias tools were used to assess the quality of the included studies. Data were reported qualitatively because heterogeneity prevented statistical pooling. Four studies satisfied the inclusion criteria and were critically appraised. The findings of the included studies indicated that spinal manipulative therapy might be effective for preventing curve progression or reducing Cobb angle. However, the lack of controls and small sample sizes precluded robust estimation of the interventions' effect sizes. There is currently insufficient evidence to establish whether spinal manipulative therapy may be beneficial for adolescent idiopathic scoliosis. The results of the included studies suggest that spinal manipulative therapy may be a promising treatment, but these studies were all at substantial risk of bias. Further high-quality studies are warranted to conclusively determine if spinal manipulative therapy may be effective in the management of adolescent idiopathic scoliosis. Copyright © 2017.

    2014-01-01

    Full Text Available Collapsing glomerulopathy (CG is a distinct clinicopathologic entity associated with various infections, medications and acute ischemia. There have been few scattered reports of CG from India. This study aimed at evaluating the clinicopathologic features of idiopathic CG in Indian patients with comparison between adult-onset and childhood CG. This study included all cases of idiopathic CG diagnosed over a period of 4 years (2006-2009. Appropriate clinical details and laboratory findings were retrieved. Renal biopsies were reviewed and detailed pathologic features assessed. Statistical analysis was performed to compare various features between adult-onset and childhood CG. Over these 4 years, 30 cases of idiopathic CG were diagnosed. Of these, 11 were children. Childhood CG cases had longer duration of symptoms and lower serum urea and creatinine levels compared with adult patients. In renal histology, tubular atrophy and interstitial fibrosis was frequent in our cases. Pediatric cases of CG showed a higher proportion of segmental glomerulosclerosis. On clinical follow-up, nine of the 30 patients progressed to end-stage renal disease and these included two pediatric patients. Idiopathic CG is a significant cause of renal dysfunction in both pediatric and adult patients. Childhood and adult-onset CG differ in few clinicopathologic features. Early and accurate diagnosis of CG is imperative for appropriate management of these patients.

    2015-11-01

    To evaluate the role of nasal bacterial colonization in cases of idiopathic epistaxis in children. A descriptive, hospital based, observational study in our hospital was conducted on total 112 pediatric patients in the age group 4-16 years. Group A (control): 56 patients with no epistaxis; Group B (epistaxis): 56 patients with idiopathic epistaxis. A swab for microbiological evaluation was taken from the anterior nasal cavity of each child. A highly significant association between nasal colonization with pathological Staphylococcus aureus and idiopathic epistaxis was found. The presence of pathological S. aureus colonization in the anterior nasal cavity was also associated with statistically significant number of crusting and presence of dilated blood vessels on the anterior nasal septum of children in epistaxis group. Nasal bacterial colonization with S. aureus leads to a sequence of pathological events i.e. low grade inflammation, crusting and new vessel formation. This leads to irritation in nasal cavity resulting in digital trauma and subsequently epistaxis and thus it plays an important role in causing idiopathic epistaxis in children.

    2014-05-01

    Full Text Available Nowadays a lot of different researches are performed based on call duration distributions (CDD analysis. However, the majority of studies are linked with social relationships between the people. Therefore the scarcity of information, how the call duration is associated with a user's location, is appreciable. The goal of this paper is to reveal the ties between user's voice call duration and the location of call. For this reason we analyzed more than 5 million calls from real mobile network, which were made over the base stations located in rural areas, roads, small towns, business and entertainment centers, residential districts. According to these site types CDD’s and characteristic features for call durations are given and discussed. Submitted analysis presents the users habits and behavior as a group (not an individual. The research showed that CDD’s of customers being them in different locations are not equal. It has been found that users at entertainment, business centers are tend to talk much shortly, than people being at home. Even more CDD can be distorted strongly, when machinery calls are evaluated. Hence to apply a common CDD for a whole network it is not recommended. The study also deals with specific parameters of call duration for distinguished user groups, the influence of network technology for call duration is considered.

    Full Text Available BACKGROUND: A close association between narcolepsy and the Human Leukocyte Antigen (HLA-DQB1*0602 allele suggests the involvement of the immune system, or possibly an autoimmune process. We investigated serum IgG levels in narcolepsy. METHODOLOGY/PRINCIPAL FINDINGS: We measured the serum total IgG levels in 159 Japanese narcolepsy-cataplexy patients positive for the HLA-DQB1*0602 allele, 28 idiopathic hypersomnia patients with long sleep time, and 123 healthy controls (the HLA-DQB1*0602 allele present in 45 subjects. The serum levels of each IgG subclass were subsequently measured. The distribution of serum IgG was significantly different among healthy controls negative for the HLA-DQB1*0602 allele (11.66+/-3.55 mg/ml, healthy controls positive for the HLA-DQB1*0602 allele (11.45+/-3.43, narcolepsy patients (9.67+/-3.38, and idiopathic hypersomnia patients (13.81+/-3.80. None of the following clinical variables, age, disease duration, Epworth Sleepiness Scale, smoking habit and BMI at the time of blood sampling, were associated with IgG levels in narcolepsy or idiopathic hypersomnia. Furthermore we found the decrease in IgG1 and IgG2 levels, stable expression of IgG3, and the increase in the proportion of IgG4 in narcolepsy patients with abnormally low IgG levels. The increase in the proportion of IgG4 levels was also found in narcolepsy patients with normal serum total IgG levels. Idiopathic hypersomnia patients showed a different pattern of IgG subclass distribution with high IgG3 and IgG4 level, low IgG2 level, and IgG1/IgG2 imbalance. CONCLUSIONS/SIGNIFICANCE: Our study is the first to determine IgG abnormalities in narcolepsy and idiopathic hypersomnia by measuring the serum IgG levels in a large number of hypersomnia patients. The observed IgG abnormalities indicate humoral immune alterations in narcolepsy and idiopathic hypersomnia. Different IgG profiles suggest immunological differences between narcolepsy and idiopathic hypersomnia.

    Muscle pain occurs in various neuromuscular disorders with characteristic physiological or biochemical abnormalities. There is, however, a group of patients in whom there is no clear physiological or structural basis for their pains. This syndrome has been called fibrositis or fibromyalgia. Sleep abnormalities have been reported in some of these patients, but have not been confirmed by others. We studied 8 patients with this disorder and found sleep abnormalities that were characterized by no...

    2007-04-07

    Bat echolocation calls provide remarkable examples of 'good design' through evolution by natural selection. Theory developed from acoustics and sonar engineering permits a strong predictive basis for understanding echolocation performance. Call features, such as frequency, bandwidth, duration and pulse interval are all related to ecological niche. Recent technological breakthroughs have aided our understanding of adaptive aspects of call design in free-living bats. Stereo videogrammetry, laser scanning of habitat features and acoustic flight path tracking permit reconstruction of the flight paths of echolocating bats relative to obstacles and prey in nature. These methods show that echolocation calls are among the most intense airborne vocalizations produced by animals. Acoustic tracking has clarified how and why bats vary call structure in relation to flight speed. Bats using broadband echolocation calls adjust call design in a range-dependent manner so that nearby obstacles are localized accurately. Recent phylogenetic analyses based on gene sequences show that particular types of echolocation signals have evolved independently in several lineages of bats. Call design is often influenced more by perceptual challenges imposed by the environment than by phylogeny, and provides excellent examples of convergent evolution. Now that whole genome sequences of bats are imminent, understanding the functional genomics of echolocation will become a major challenge.

  3. The function of Barbary macaque copulation calls.

    Science.gov (United States)

    Semple, S

    1998-02-22

    In a wide variety of animal species, females produce vocalizations specific to mating contexts. It has been proposed that these copulation calls function to incite males to compete for access to the calling female. Two separate advantages of inciting male-male competition in this way have been put forward. The first suggests that as a result of calling, females are only mated by the highest ranking male in the vicinity (indirect mate choice hypothesis). The second proposes that copulation calling results in a female being mated by many males, thus promoting competition at the level of sperm (sperm competition hypothesis). In this paper, I give results from the first experimental study to test these hypotheses. Playback was used to examine the function of copulation calls of female Barbary macaques (Macaca sylvanus) in Gibraltar. Although rank did not affect lone males' likelihood of approaching copulation calls, when playbacks were given to pairs of males only the higher ranking individual approached. Moreover, females were mated significantly sooner after playback of their copulation call than after playback of a control stimulus. These results suggest that the copulation calls of female Barbary macaques play a key role in affecting patterns of male reproductive behaviour, not only providing an indirect mechanism of female choice, but also promoting sperm competition by reducing the interval between copulations. Potential fitness benefits of inciting male-male competition at these two levels are discussed.

  5. Bat echolocation calls: Orientation to communication

    Fenton, M. Brock

    2004-05-01

    Bats hunting flying insects adjust the design of their echolocation calls according to the situation in which they forage and stage in an attack. Changes in call design across attack sequences alert other bats within earshot to the presence of prey, demonstrating a continuum in roles for biosonar signals between orientation and communication. Many aerial-feeding bats change the design of their echolocation calls in the presence of echolocating conspecifics. Bats may change frequency parameters, durations, and/or intensities of their calls. While a variety of free-tailed bats (Molossidae Otomops martiensseni, Tadarida teniotis, Molossus molossus) consistently change their echolocation calls when more than one bat is flying in an area, at least one sheath-tailed bat (Emballonuridae Taphozous perforatus) does not. Changes in echolocation calls may maximize jamming avoidance and/or enhance the communicative function of the calls. The data for molossids support the hypothesis that when hunting some species fly in formation. Here, variation in individual call design could provide positional information and reduce the chances of mid-air collisions.

    2014-02-01

    Animals emit vocalizations that convey information about external events. Many of these vocalizations, including those emitted in response to predators, also encode information about the individual that produced the call. The relationship between acoustic features of antipredator calls and information relating to signalers (including sex, identity, body size, and social rank) were examined in peafowl (Pavo cristatus). The "bu-girk" antipredator calls of male and female peafowl were recorded and 20 acoustic parameters were automatically extracted from each call. Both the bu and girk elements of the antipredator call were individually distinctive and calls were classified to the correct signaler with over 90% and 70% accuracy in females and males, respectively. Females produced calls with a higher fundamental frequency (F0) than males. In both females and males, body size was negatively correlated with F0. In addition, peahen rank was related to the duration, end mean frequency, and start harmonicity of the bu element. Peafowl antipredator calls contain detailed information about the signaler and can potentially be used by receivers to respond to dangerous situations.

    2018-02-01

    Humpback whales produce a wide range of low- to mid-frequency vocalizations throughout their migratory range. Non-song "calls" dominate this species' vocal repertoire while on high-latitude foraging grounds. The source levels of 426 humpback whale calls in four vocal classes were estimated using a four-element planar array deployed in Glacier Bay National Park and Preserve, Southeast Alaska. There was no significant difference in source levels between humpback whale vocal classes. The mean call source level was 137 dB RMS re 1 μPa @ 1 m in the bandwidth of the call (range 113-157 dB RMS re 1 μPa @ 1 m), where bandwidth is defined as the frequency range from the lowest to the highest frequency component of the call. These values represent a robust estimate of humpback whale source levels on foraging grounds and should append earlier estimates.

  14. Call Admission Control in Mobile Cellular Networks

    CERN Document Server

    Ghosh, Sanchita

    2013-01-01

    Call Admission Control (CAC) and Dynamic Channel Assignments (DCA) are important decision-making problems in mobile cellular communication systems. Current research in mobile communication considers them as two independent problems, although the former greatly depends on the resulting free channels obtained as the outcome of the latter. This book provides a solution to the CAC problem, considering DCA as an integral part of decision-making for call admission. Further, current technical resources ignore movement issues of mobile stations and fluctuation in network load (incoming calls) in the control strategy used for call admission. In addition, the present techniques on call admission offers solution globally for the entire network, instead of considering the cells independently.      CAC here has been formulated by two alternative approaches. The first approach aimed at handling the uncertainty in the CAC problem by employing fuzzy comparators.  The second approach is concerned with formulation of CAC ...

    Full Text Available Purpose: Unilateral or bilateral testicular pain lasting more than 3 months is called as chronic orchialgia. Aproximately 25-50% of chronic orchialgia is idiopatic origin. This study aimed the effectiveness of Transcutaneous Electrical Nerve Stimulation (TENS therapy due to Idiopathic Chronic Orchialgia (ICO. Methods: Five patients were included into this study with ICO that diagnosed with physical examination, urine analyses, urinary system x-ray film, and scrotal doppler ultrasound. Medical history revealed that multiple conservative therapy attempts failed to alleviate the pain. Two of the patients had right sided ICO. Traditional TENS device is placed to the most painful points. TENS applied 3 times in a week with duration 30 minutes for 4 weeks. Before and after TENS application, patients were evaluated by using Visual Analog Scale (VAS at first and third months. Results: Median age of patients was 26.20±2.38 (22-30. Mean VAS value was 6.52 ± 0.89 before the procedure. After 1 month VAS value was 3.82 ± 0.83 (p0.05. None of the patients needed any analgesics after during the one month. No complications, hyperemia or hypoesthesia of the scrotal or penile skin, occurred after the procedure. Conclusion: TENS reduces pain by increasing endorphin release in the spinal cord dorsal horn. TENS is very effective method for first 1 month in patients with ICO but its effect reduces by the time. There is no standard therapeutic protocol for idiopathic chronic orchialgia. Therefore TENS may be an alternative for patients who do not benefit from medical therapy and do not want invasive procedures. Short-term use of TENS and low number of the patients are the limitations of this study. Randomized, placebo-controlled, and longer follow-up period studies are needed to better assess the efficacy of TENS for ICO.

    The etiology of idiopathic carpal tunnel syndrome has not been clarified. We evaluated cross sectional area of carpal tunnel, flexor tendons, median nerve and thickness of transverse carpal ligament by enhanced MRI. Twenty-six patients were tested who has been diagnosed based on electromyogram and clinical symptons as idiopathic carpal tunnel syndrome. All patients were female and the mean age was 64 years old. The cross sectional area of carpal tunnel, the median nerve, the flexor tendons and synovium around them in carpal tunnel were calculated. And the thickness of the transverse carpal ligament as well. The mean area of the flexor tendons with synovium in carpal tunnel was 110.5{+-}25.5 mm{sup 2} (control group; 79.3{+-}13.8 mm{sup 2}), ratio of flexor tendon area to carpal tunnel area was 51.6{+-}8.9% (control; 40.5{+-}2.4%), and the thickness of the transverse carpal ligament was 3.3{+-}0.5 mm (control; 2.5{+-}0.4 mm) in severe idiopathic carpal tunnel syndrome. The mean area of the flexor tendons with synovium in severe idiopathic carpal tunnel syndrome was significantly greater than that of mild type (p<0.05). In such a process, we could classify these MRI findings into the following four subgroups. Enlargement of cross sectional area of flexor tendons and synovium (n=8; 25.8%), thickened transverse carpal ligament (n=11; 35.5%), combined type (n=7; 22.6%) and impossible to classify (n=5; 16.1%). This classification with enhanced MRI was correlated to clinical course and electrophysiologic severity. In conclusion, we can suggest that to evaluate cross sectional area of the wrist (carpal tunnel) with enhanced MRI is one of the useful assistant method for diagnosing and investigating the etiology of severe idiopathic carpal tunnel syndrome.

    The incidence of cesarean section has been rising in the past 50 years. With the increased number of cesarean sections, the number of pregnancies with the previous cesarean section rises as well. The aim of this study was to establish the influence of the previous cesarean section on the development of placental complications: placenta previa, placental abruption and placenta accreta, as well as to determine the influence of the number of previous cesarean sections on the complication development. The research was conducted at the Clinic of Gynecology and Obstetrics in Nis covering 10-year-period (from 1995 to 2005) with 32358 deliveries, 1280 deliveries after a previous cesarean section, 131 cases of placenta previa and 118 cases of placental abruption. The experimental groups was presented by the cases of placenta previa or placental abruption with prior cesarean section in obstetrics history, opposite to the control group having the same conditions but without a cesarean section in medical history. The incidence of placenta previa in the control group was 0.33%, opposite to the 1.86% incidence after one cesarean section (pcesarean sections and as high as 14.28% after three cesarean sections in obstetric history. Placental abruption was recorded as placental complication in 0.33% pregnancies in the control group, while its incidence was 1.02% after one cesarean section (pcesarean sections. The difference in the incidence of intrapartal hysterectomy between the group with prior cesarean section (0.86%) and without it (0.006%) shows a high statistical significance (pcesarean section is an important risk factor for the development of placental complications.

    Without antiresorptive therapy, postmenopausal women lose bone mass after teriparatide (TPTD) discontinuation; estrogen treatment prevents bone loss in this setting. It is not known whether premenopausal women with regular menses lose bone mass after teriparatide discontinuation. This study aimed to test the hypothesis that normally menstruating premenopausal women with idiopathic osteoporosis (IOP) will maintain teriparatide-associated bone mineral density (BMD) gains after medication cessation. Twenty-one premenopausal IOP women previously enrolled in an open-label pilot study of teriparatide (20 mcg for 18-24 mo), had substantial BMD increases at the lumbar spine (LS; 10.8 ± 8.3%), total hip (TH; 6.2 ± 5.6%), and femoral neck (7.6 ± 3.4%). For this study, BMD was remeasured 2.0 ± 0.6 years after teriparatide cessation. Fifteen women, who had gained 11.1 ± 7.2% at LS and 6.1 ± 6.5% at TH and were premenopausal at teriparatide completion, were followed without antiresorptive treatment. Two years after completing teriparatide, BMD declined by 4.8 ± 4.3% (P = .0007) at the LS. In contrast, BMD remained stable at the femoral neck (-1.5 ± 4.2%) and TH (-1.1 ± 3.7%). Those who sustained LS bone loss >3% (-7.3 ± 2.9%; n = 10), did not differ from those with stable LS BMD (0.1 ± 1.1%; n=5) with regard to baseline body mass index, BMD at any site, or duration of followup, but were significantly older at re-evaluation (46 ± 3 vs 38 ± 7; P = .046), had larger increases in LS BMD during teriparatide treatment and higher cancellous bone remodeling on transiliac biopsy at baseline and completion of teriparatide treatment. Serum bone turnover markers did not differ at baseline or teriparatide completion, but tended to be higher at the re-evaluation timepoint in those with post-teriparatide bone loss. These findings lead us to conclude that premenopausal women with IOP, particularly those over 40, may require antiresorptive treatment to prevent bone loss after

    To describe the long-term outcomes of children at school age who were thought to have isolated idiopathic congenital talipes equino varus (ICTEV) at birth. A retrospective review of all children attending a regional talipes clinic who had achieved school age. One hundred sixty-three children were followed up. ICTEV was more common in Maori and other Polynesian children and in males. Additional abnormalities were apparent in 30.1% overall, but higher in New Zealand Europeans (43%) than Maori (21%) or other Polynesians (22%). Of the abnormalities, 41% were associated with the central nervous system or with neurodevelopmental delay. Conventional G-band karyotyping, where performed, was not informative. The rate of additional abnormalities was higher than previous reports. This has implications for prenatal counseling and postnatal follow-up as a prenatal diagnosis of ICTEV may subsequently be found to have longer term implications in addition to orthopedic treatments of the clubfeet.

The human ryanodine receptor 2 (RYR2 is one of the key players tightly regulating calcium efflux from the sarcoplasmic reticulum to the cytosol and found frequently mutated (T; p.D4631V in a CPVT patient and a novel rare variant (c5428G>C; p.V1810L of uncertain significance in a patient with VT of idiopathic origin which we suggest represents a low-penetrance or susceptibility variant. In addition we identified a known variant previously associated with arrhythmogenic right ventricular dysplasia type2 (ARVD2. Combining sets of prediction scores and reference databases appeared fundamental to predict the pathogenic potential of novel and rare missense variants in populations where genotype data are rare.

    2015-10-01

    Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is recognized as a preneoplastic condition by the World Health Organization. We reviewed our experience with 30 patients and performed a systematic review of the English literature to collect best evidence on the clinical features and disease course in 169 additional patients. Some patients presented with one or more carcinoid tumors associated with multiple small pulmonary nodules on imaging studies and showed DIPNECH as a somewhat unexpected pathologic finding. Others presented with multiple small pulmonary nodules that raised suspicion of metastatic disease on imaging. A third subset was presented with previously unexplained respiratory symptoms. In most patients, DIPNECH was associated with a good prognosis, with chronological progression into a subsequent carcinoid tumor noted in only one patient and death attributed directly to DIPNECH in only two patients. There is no best evidence to support the use of octreotide, steroids, or bronchodilators in DIPNECH patients.

    2016-01-01

    Full Text Available Asymmetric ventriculomegly due to idiopathic occlusion of the foramen of Monro is rare. Such patients present with clinical features of raised intracranial pressure (ICP. Presentation as chronic headache has not been previously described. In the absence of raised ICP, pursuing surgical treatment raises a clinical dilemma as the headache may be a primary headache with no improvement after surgery. A 21-year-old woman presented with chronic headache. She was found to have asymmetric ventriculomegaly due to the occlusion of the foramen of Monro. She underwent endoscopic septostomy and widening of the foramen of Monro. Her headache subsided after surgery. At 15 months of follow-up, she was free from headache without medications. Unilateral occlusion of the foramen of Monro can present with asymmetric ventriculomegaly resulting in chronic headache. Though the symptoms of raised ICP may not be present, still endoscopic relief of ventriculomegaly leads to cure of headache.

    2016-01-01

    Whether or not wind turbines pose a risk to human health is a matter of heated debate. Personal reactions to other environmental exposures occurring in the same settings as wind turbines may be responsible of the reported symptoms. However, these have not been accounted for in previous studies. We investigated whether there is an association between residential proximity to wind turbines and idiopathic symptoms, after controlling for personal reactions to other environmental co-exposures. We assessed wind turbine exposures in 454 residences as the distance to the closest wind turbine (Dw) and number of wind turbines turbines and agricultural odor exposure, we did not observe a significant relationship between residential proximity to wind turbines and symptoms and the parameter estimates were attenuated toward zero. Wind turbines-health associations can be confounded by personal reactions to other environmental co-exposures. Isolated associations reported in the literature may be due to confounding bias.

After cessation of bisphosphonate treatment in children, skeletal radiologic changes have been documented including dense metaphyseal lines of the long bones and “bone in bone” appearance of the vertebrae. However, the evolution of these radiographic changes has not been fully explored. We describe the MR imaging appearance of the spine that, to our knowledge, has not been previously addressed in a child with idiopathic juvenile osteoporosis who had received bisphosphonates and emphasize the evolution of the radiographic findings of the spine and pelvis over a four-year period.

  10. External GSM phone calls now made simpler

    CERN Multimedia

    2007-01-01

    On 2 July, the IT/CS Telecom Service introduced a new service making external calls from CERN GSM phones easier. A specific prefix is no longer needed for calls outside CERN. External calls from CERN GSM phones are to be simplified. It is no longer necessary to use a special prefix to call an external number from the CERN GSM network.The Telecom Section of the IT/CS Group is introducing a new system that will make life easier for GSM users. It is no longer necessary to use a special prefix (333) to call an external number from the CERN GSM network. Simply dial the number directly like any other Swiss GSM customer. CERN currently has its own private GSM network with the Swiss mobile operator, Sunrise, covering the whole of Switzerland. This network was initially intended exclusively for calls between CERN numbers (replacing the old beeper system). A special system was later introduced for external calls, allowing them to pass thr...

  11. Discrepancy in clinical versus radiological parameters describing deformity due to brace treatment for moderate idiopathic scoliosis

    2007-12-01

    Full Text Available Abstract Background The shape of the torso in patients with idiopathic scoliosis is considered to reflect the shape of the vertebral column, however the direct correlation between parameters describing clinical deformity and those characterizing radiological curvature was reported to be weak. It is not clear if the management proposed for scoliosis (physiotherapy, brace, surgery affects equally the shape of the axial skeleton and the surface of the body. The aim of the study was to compare clinical deformity of (1 idiopathic scoliosis girls being under brace treatment for radiological curves of 25 to 40 degrees and (2 non treated scoliotic girls matched for age and Cobb angle. Methods Cross-sectional study of 24 girls wearing the brace versus 26 girls without brace treatment, matched for age and Cobb angle. Hypothesis: Patients wearing the brace for more than 6 months, when comparing to patients without brace, may present different external morphology of the trunk, in spite of having similar Cobb angle. Material. Inclusion criteria: girls, idiopathic scoliosis, growing age (10–16 years, Cobb angle minimum 25°, maximum 40°. The braced group consisted of girls wearing a TLSO brace (Cheneau for more than 6 months with minimum of 16 hours per day. The non-braced group consisted of girls first seen for their spinal deformity, previously not treated. The groups presented similar curve pattern. Methods. Scoliometer exam: angle of trunk rotation at three levels of the spine: upper thoracic, main thoracic, lumbar or thoracolumbar. The maximal angle was noted at each level and the sum of three levels was calculated. Posterior trunk symmetry index (POTSI and Hump Sum were measured using surface topography. Results Cobb angle was 34.9° ± 4.8° in braced and 32.7° ± 4.9° in un-braced patients (difference not significant. The age was 14.1 ± 1.6 years in braced patients and 13.1 ± 1.9 years in un-braced group (p = 0.046. The value of angle of trunk

    Background: Accurate skeletal maturity assessment is important to guide clinical evaluation of idiopathic scoliosis, but commonly used methods are inadequate or too complex for rapid clinical use. The objective of the study was to propose a new simplified staging method, called the thumb ossification composite index (TOCI), based on the ossification pattern of the 2 thumb epiphyses and the adductor sesamoid bone; to determine its accuracy in predicting skeletal maturation when compared with the Sanders simplified skeletal maturity system (SSMS); and to validate its interrater and intrarater reliability. Methods: Hand radiographs of 125 girls, acquired when they were newly diagnosed with idiopathic scoliosis prior to menarche and during longitudinal follow-up until skeletal maturity (a minimum of 4 years), were scored with the TOCI and SSMS. These scores were compared with digital skeletal age (DSA) and radius, ulna, and small hand bones (RUS) scores; anthropometric data; peak height velocity; and growth-remaining profiles. Correlations were analyzed with the chi-square test, Spearman and Cramer V correlation methods, and receiver operating characteristic curve analysis. Reliability analysis using the intraclass correlation (ICC) was conducted. Results: Six hundred and forty-five hand radiographs (average, 5 of each girl) were scored. The TOCI staging system was highly correlated with the DSA and RUS scores (r = 0.93 and 0.92, p 0.97. Conclusions: The new proposed TOCI could provide a simplified staging system for the assessment of skeletal maturity of subjects with idiopathic scoliosis. The index needs to be subjected to further multicenter validation in different ethnic groups. PMID:28872525

  14. Echolocation calls and communication calls are controlled differentially in the brainstem of the bat Phyllostomus discolor

    Science.gov (United States)

    Fenzl, Thomas; Schuller, Gerd

    2005-01-01

    Background Echolocating bats emit vocalizations that can be classified either as echolocation calls or communication calls. Neural control of both types of calls must govern the same pool of motoneurons responsible for vocalizations. Electrical microstimulation in the periaqueductal gray matter (PAG) elicits both communication and echolocation calls, whereas stimulation of the paralemniscal area (PLA) induces only echolocation calls. In both the PAG and the PLA, the current thresholds for triggering natural vocalizations do not habituate to stimuli and remain low even for long stimulation periods, indicating that these structures have relative direct access to the final common pathway for vocalization. This study intended to clarify whether echolocation calls and communication calls are controlled differentially below the level of the PAG via separate vocal pathways before converging on the motoneurons used in vocalization. Results Both structures were probed simultaneously in a single experimental approach. Two stimulation electrodes were chronically implanted within the PAG in order to elicit either echolocation or communication calls. Blockade of the ipsilateral PLA site with iontophoretically application of the glutamate antagonist kynurenic acid did not impede either echolocation or communication calls elicited from the PAG. However, blockade of the contralateral PLA suppresses PAG-elicited echolocation calls but not communication calls. In both cases the blockade was reversible. Conclusion The neural control of echolocation and communication calls seems to be differentially organized below the level of the PAG. The PLA is an essential functional unit for echolocation call control before the descending pathways share again the final common pathway for vocalization. PMID:16053533

    People in modern societies form different social networks through numerous means of communication. These communication networks reflect different aspects of human's societal structure. The billing records of calls among mobile phone users enable us to construct a directed calling network (DCN) and its Bonferroni network (SVDCN) in which the preferential communications are statistically validated. Here we perform a comparative investigation of the cliques of the original DCN and its SVDCN constructed from the calling records of more than nine million individuals in Shanghai over a period of 110 days. We find that the statistical properties of the cliques of the two calling networks are qualitatively similar and the clique members in the DCN and the SVDCN exhibit idiosyncratic behaviors quantitatively. Members in large cliques are found to be spatially close to each other. Based on the clique degree profile of each mobile phone user, the most active users in the two calling networks can be classified in to several groups. The users in different groups are found to have different calling behaviors. Our study unveils interesting communication behaviors among mobile phone users that are densely connected to each other.

    CSF volumes in the basal cistern and Sylvian fissure are increased in both idiopathic normal pressure hydrocephalus and Alzheimer disease, though the differences in these volumes in idiopathic normal pressure hydrocephalus and Alzheimer disease have not been well-described. Using CSF segmentation and volume quantification, we compared the distribution of CSF in idiopathic normal pressure hydrocephalus and Alzheimer disease. CSF volumes were extracted from T2-weighted 3D spin-echo sequences on 3T MR imaging and quantified semi-automatically. We compared the volumes and ratios of the ventricles and subarachnoid spaces after classification in 30 patients diagnosed with idiopathic normal pressure hydrocephalus, 10 with concurrent idiopathic normal pressure hydrocephalus and Alzheimer disease, 18 with Alzheimer disease, and 26 control subjects 60 years of age or older. Brain to ventricle ratios at the anterior and posterior commissure levels and 3D volumetric convexity cistern to ventricle ratios were useful indices for the differential diagnosis of idiopathic normal pressure hydrocephalus or idiopathic normal pressure hydrocephalus with Alzheimer disease from Alzheimer disease, similar to the z-Evans index and callosal angle. The most distinctive characteristics of the CSF distribution in idiopathic normal pressure hydrocephalus were small convexity subarachnoid spaces and the large volume of the basal cistern and Sylvian fissure. The distribution of the subarachnoid spaces in the idiopathic normal pressure hydrocephalus with Alzheimer disease group was the most deformed among these 3 groups, though the mean ventricular volume of the idiopathic normal pressure hydrocephalus with Alzheimer disease group was intermediate between that of the idiopathic normal pressure hydrocephalus and Alzheimer disease groups. The z-axial expansion of the lateral ventricle and compression of the brain just above the ventricle were the common findings in the parameters for differentiating

  19. Growth factors in idiopathic pulmonary fibrosis: relative roles

    Directory of Open Access Journals (Sweden)

    Allen Jeremy T

    2001-11-01

    Full Text Available Abstract Treatment of idiopathic pulmonary fibrosis patients has evolved very slowly; the fundamental approach of corticosteroids alone or in combination with other immunosuppressive agents has had little impact on long-term survival. The continued use of corticosteroids is justified because of the lack of a more effective alternative. Current research indicates that the mechanisms driving idiopathic pulmonary fibrosis reflect abnormal, dysregulated wound healing within the lung, involving increased activity and possibly exaggerated responses by a spectrum of profibrogenic growth factors. An understanding of the roles of these growth factors, and the way in which they modulate events at cellular level, could lead to more targeted therapeutic strategies, improving patients' quality of life and survival.

  20. Successful treatment of idiopathic pulmonary capillaritis with intravenous cyclophosphamide.

    LENUS (Irish Health Repository)

    2013-03-01

    Idiopathic pulmonary hemosiderosis (IPH), a subtype of diffuse alveolar hemorrhage is a rare condition, first described by Virchow in 1864. Historically, it manifests in children in the first decade of life with the combination of hemoptysis, iron deficiency anemia, and alveolar infiltrates on chest radiograph. More recently, diffuse alveolar hemorrhage has been classified by the absence or presence of pulmonary capillaritis (PC), the latter carrying a potential for a poorer outcome. While systemic corticosteroids remain the first line treatment option, other immune modulators have been trailed including hydroxychloroquine, azathioprine, 6-mercaptopurine, and cyclophosphamide with varying results. Our case demonstrates for the first time, the successful use of intravenous cyclophosphamide in the management of chronic idiopathic PC.

    Full Text Available Introduction. Fahr´s syndrome is a rare, slowly progressive, neurodegenerative disorder, characterised by extensive, bilateral, and symmetrical basal ganglia calcification. It is associated with neuropsychiatric manifestations and gradually progressive cognitive impairment. Fahr's syndrome is the secondary form of brain calcification that is caused by various metabolic, infectious, or degenerative diseases. Case report. We presented a middle-aged male with Fahr's syndrome due to primary idiopathic hypoparathyroidism. Clinical diagnosis was based on signs and symptoms of hypocalcemia, progressive neuropsychiatric illnesses, laboratory evidence of hypoparathyroidism, and radiological signs of calcifications in the basal ganglia. The patient improved after only a few days of intravenous rehydration and calcium substitution, followed by oral supplemental calcitriol. Conclusion. Timely recognition of idiopathic and iatrogenic hypoparathyroidism allows appropriate treatment that can prevent the development and clinical manifestations of Fahr´s syndrome and potentially slow its progression.

    Acquired atresia of the ear canal presents rarely in children. Idiopathic inflammatory medial meatal fibrotizing otitis (IMFO) evidently has its own distinct etiopathologic findings causing acquired ear canal atresia. Two IMFO children treated and followed-up at the Department of Otorhinolaryngology of Helsinki University Hospital. Clinical and radiologic evaluation of 2 children with IMFO solely affecting the glabrous skin over the osseous part of the ear canal and the tympanic membrane. Review of identical cases of the acquired postinflammatory or inflammatory medial meatal atresia in children reported in association with literature. Idiopathic inflammatory medial meatal fibrotizing otitis, affecting solely the glabrous skin on the tympanic membrane and the osseous part of the external ear canals, is manifesting in 2 children without ongoing chronic middle ear infection. The etiopathologic findings or pathophysiology of IMFO is speculative. The success of surgical correction of the already-formed fibrous atresia has not been established.

Retrospective review of the clinical presentation, MRI findings and outcome of three patients diagnosed with acute idiopathic transverse myelitis. Of note was the swift onset of symptoms in all patients, without any preceding illness or history of vaccination in two of the patients, and the rapid resolution of symptoms on steroid therapy in all the patients. MRI showed T2-weighted hyperintensity and patchy enhancement with gadolinium, but the extensive cord involvement did not correlate with the severity of presentation or outcome. Our findings do not support that MRI evidence alone of diffuse myelopathy is a predictor of poor outcome in childhood AIM. (orig.)

    Cutaneous extramedullary hematopoiesis is a rare manifestation of chronic myeloproliferative processes, mainly chronic idiopathic myelofibrosis. In adults, it manifests as macules, papules, nodules, and ulcers on the trunk. The lesions usually appear soon after diagnosis and the possibility of a relationship between splenectomy and the appearance of extramedullary foci of hematopoiesis is still debated. Diagnosis is based on histopathology showing an infiltrate with different combinations of myeloid and erythroid cell precursors and megakaryocytes. Symptomatic treatment is provided alongside treatment of the underlying disease. We report a new case associated with chronic idiopathic myelofibrosis in which foci of cutaneous extramedullary hematopoiesis were observed 9 years after initial diagnosis. The lesions were progressive and the patient went on to develop acute myeloid leukemia.

    Full Text Available The efficacy of flutamide, an antiandrogen in idiopathic hirsutism was studied. The long term effects of. treatment with low doses of flutamide on clinical and hormonal parameters were investigated. Nine patients with idiopathic hirsutism were studied basally and during treatment with 125mg flutamide thrice daily for a period of 9 months. Safety parameters were assessed throughout the study. Hirsutism was graded by Ferriman and Gallwey score and hormones were evaluated basally and later quarterly. After three months of therapy, flutamide had caused a significant alleviation of hirsutism and this continued during the subsequent months. No clinical significant side effects were observed during the period of the study. Biochemical and hormonal parameters remained unchanged after 9 months of flutamide.

    Full Text Available The idiopathic hypereosinophilic sindrome (HES is a disease characterized by persistent blood eosinophilia (> 1500 eosinophils/mm3 > 6 months-in absence of other ethiologies for eosinophilia (parasitic, allergic, immunological or malignant diseases-associated with multiple organ involvement (heart, lung, central nervous system, skin, bone marrow, gastrointestinal tract. Reports on rheumatologic manifestations in patients with HES are very rare. In the case we report a typical rheumatoid arthritis developed in a 58-year-old woman with HES treated with glucocorticoids. Because of the marked glucocorticoids side effects shown by the patient(cushingoid habitus, hyperglycemia, we stopped this treatment and replaced it at first by methotrexate and later by cyclosporin, both of them associated with sulfasalazine. These drugs revealed very efficacious both on articular pathology and on the clinical and laboratory manifestations of HES. These data suggest that common pathogenetic mechanisms are likely acting in rheumatoid arthritis and idiopathic hypereosinophilic syndrome.

    A case of chronic idiopathic intestinal pseudo-obstruction in an English bulldog is described. The dog was presented with chronic weight loss and vomiting. An intestinal obstruction was suspected based on clinical and radiological findings. A diagnosis of chronic idiopathic intestinal pseudo-obstruction was made on the basis of full thickness intestinal biopsies. The dog was refractory to any antiemetic therapy. Necropsy revealed marked atrophy and fibrosis of the tunica muscularis, together with a mononuclear cell infiltrate extending from the duodenum to the colon. This case was presented with clinical findings consistent with visceral myopathy in humans--namely, atony and dilatation of the whole gut--but the histological findings resembled sclerosis limited to the gastrointestinal tract.

    2014-01-01

    For the 20(th) century since the Depression, we find a strong correlation between a 'literary misery index' derived from English language books and a moving average of the previous decade of the annual U.S. economic misery index, which is the sum of inflation and unemployment rates. We find a peak in the goodness of fit at 11 years for the moving average. The fit between the two misery indices holds when using different techniques to measure the literary misery index, and this fit is significantly better than other possible correlations with different emotion indices. To check the robustness of the results, we also analysed books written in German language and obtained very similar correlations with the German economic misery index. The results suggest that millions of books published every year average the authors' shared economic experiences over the past decade.

    Full Text Available Introduction The rate of operative birth by Caesarean section is constantly rising. In Kazakhstan, it reaches 27 per cent. Research data confirm that the percentage of successful vaginal births after previous Caesarean section is 50–70 per cent. How safe the induction of vaginal birth after Caesarean (VBAC remains unclear. Methodology The studied techniques of labour induction were amniotomy of the foetal bladder with the vulsellum ramus, intravaginal administration of E1 prostaglandin (Misoprostol, and intravenous infusion of Oxytocin-Richter. The assessment of rediness of parturient canals was conducted by Bishop’s score; the labour course was assessed by a partogram. The effectiveness of labour induction techniques was assessed by the number of administered doses, the time of onset of regular labour, the course of labour and the postpartum period and the presence of complications, and the course of the early neonatal period, which implied the assessment of the child’s condition, described in the newborn development record. The foetus was assessed by medical ultrasound and antenatal and intranatal cardiotocography (CTG. Obtained results were analysed with SAS statistical processing software. Results The overall percentage of successful births with intravaginal administration of Misoprostol was 93 per cent (83 of cases. This percentage was higher than in the amniotomy group (relative risk (RR 11.7 and was similar to the oxytocin group (RR 0.83. Amniotomy was effective in 54 per cent (39 of cases, when it induced regular labour. Intravenous oxytocin infusion was effective in 94 per cent (89 of cases. This percentage was higher than that with amniotomy (RR 12.5. Conclusions The success of vaginal delivery after previous Caesarean section can be achieved in almost 70 per cent of cases. At that, labour induction does not decrease this indicator and remains within population boundaries.

    To clarify the time course of recovery in patients with idiopathic vocal fold paralysis. Retrospective chart review. Medical records for all patients with idiopathic vocal fold paralysis over a 10-year period were reviewed to obtain demographic and clinical information, including onset of disease and recovery of vocal function. Stroboscopic exams of patients who recovered voice were reviewed blindly to assess return of vocal fold motion. Thirty-eight of 55 patients (69%) recovered vocal function. Time course of recovery could be assessed in 34 patients who did not undergo injection augmentation. The mean time to recovery was 152.8 ± 109.3 days (left, 179.8 ± 111.3 days; right, 105.3 ± 93.7 days; P = .088). Two-thirds of patients recovered within 6 months. Probability of recovery declined over time. Five of 22 patients who recovered voice had return of vocal fold motion; 17 did not. The mean time to recovery did not differ between these groups (return of motion, 127.4 ± 132.3 days; no return of motion, 160.1 ± 105.1 days; P = .290). Sixty-nine percent of patients with idiopathic vocal fold paralysis recovered vocal function, two-thirds doing so within 6 months of onset. Age, gender, laterality, use of injection augmentation did not influence recovery rate. Declining probability of recovery over time leads us to consider framework surgery after 6 months in patients with idiopathic paralysis. 4.

    Many radiologists find it challenging to distinguish between the different interstitial idiopathic pneumonias (IIPs). The British Thoracic Society guidelines on interstitial lung disease (2008) recommend the formation of multidisciplinary meetings, with diagnoses made by combined radiological, pathological, and clinical findings. This review focuses on understanding typical and atypical radiological features on high-resolution computed tomography between the different IIPs, to help the radiologist determine when a confident diagnosis can be made and how to deal with uncertainty.

    In a series of 36 consecutive patients with proved idiopathic hemochromatosis and with a mean follow-up time of 8 years, 10 patients developed 11 carcinomas (30.6%). Five patients had hepatomas and six patients extrahepatic carcinoma involving lungs (four), oral cavity (one), and thyroid (one). The findings suggest a causal relationship between hemochromatosis and extrahepatic cancer. The evidence of an increased cancer risk in relation to cirrhosis and to iron toxicity are discussed.

    Bilateral facial nerve palsy or facial diplegia is a rare condition that occurs mainly in the context of Guillain-Barré syndrome. Its natural history has never been studied. We report four patients with isolated idiopathic bilateral facial nerve palsy with meningitis, no evidence of Guillain-Barré syndrome and rapid and complete recovery. Our report aims to draw attention to an unusual variant of bilateral facial palsy. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available Spontaneous adrenal hemorrhage (SAH is seen in the absence of trauma or adrenal tumor in adrenal glands. The incidence of SAH has been reported from 0.14% to 1.1% and it usually involves the right gland. During pregnancy, idiopathic unilateral SAH has been reported rarely. We present a case which comes to emergency department with an acute abdominal pain and the test results showed spontaneous left SAH.

    Forty-two African patients with chronic idiopathic thrombocytopenic purpura (ITP) seen at the Kenyatta National Hospital, Nairobi, Kenya between June 1975 and June 1981 were used in this study. The disease appears to behave no differently from that in Western populations with regard to clinical and haematological features. Specific problems related to the disease in an African setting and the clinical significance of recognizing the disorder especially in a tropical environment are briefly pointed out.

    Idiopathic inflammatory myopathies are comprised of polymyositis (PM) and dermatomyositis (DM) with muscle impairment being the primary clinical feature. With the currently recommended treatment regimen, a majority of patients develop sustained impaired muscle performance and poor health for undetermined reasons. The overall aim was to test the hypothesis that sustained muscle impairment and poor health in patients with established PM/DM are consequences of low aerobic capacity and that the u...
