  1. A novel mutation causing mild, atypical fumarylacetoacetase deficiency (Tyrosinemia type I: a case report

    Kvittingen Eli-Anne


    Full Text Available Abstract A male patient, born to unrelated Belgian parents, presented at 4 months with epistaxis, haematemesis and haematochezia. On physical examination he presented petechiae and haematomas, and a slightly enlarged liver. Serum transaminases were elevated to 5-10 times upper limit of normal, alkaline phosphatases were 1685 U/L (180 s ( Fumarylacetoacetase (FAH protein and activity in cultured fibroblasts and liver tissue were decreased but not absent. 4-hydroxyphenylpyruvate dioxygenase activity in liver was normal, which is atypical for tyrosinemia type I. A novel mutation was found in the FAH gene: c.103G>A (Ala35Thr. In vitro expression studies showed this mutation results in a strongly decreased FAH protein expression. Dietary treatment with phenylalanine and tyrosine restriction was initiated at 4 months, leading to complete clinical and biochemical normalisation. The patient, currently aged 12 years, shows a normal physical and psychomotor development. This is the first report of mild tyrosinemia type I disease caused by an Ala35Thr mutation in the FAH gene, presenting atypically without increase of the diagnostically important toxic metabolites succinylacetone and succinylacetoacetate.

  2. Atypical B12 Deficiency with Nonresolving Paraesthesia

    Haider, S.; Ahmad, N; Anaissie, E J; Abdel Karim, N.


    Vitamin B12 deficiency can present with various hematological, gastrointestinal and neurological manifestations. We report a case of elderly female who presented with neuropathy and vitamin B12 deficiency where the final work-up revealed polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS). This case suggests that, although POEMS syndrome is a rare entity, it can present with vitamin-B12 deficiency and thus specific work up for early diagnosis of P...

  3. Purification, crystallization and preliminary X-ray analysis of the fumarylacetoacetase family member TTHA0809 from Thermus thermophilus HB8

    The putative fumarylacetoacetase TTHA0809 from T. thermophilus HB8 has been overexpressed, purified and crystallized. The crystals diffracted X-rays to 2.2 Å resolution using synchrotron radiation. Fumarylacetoacetase catalyzes the final step of tyrosine and phenylalanine catabolism. A recombinant form of the fumarylacetoacetase family member TTHA0809 from Thermus thermophilus HB8 has been crystallized by the oil-microbatch method using sodium chloride as a precipitating agent. The crystals belong to the monoclinic space group P21, with unit-cell parameters a = 93.3, b = 73.4, c = 122.6 Å, β = 111.8°. The crystals are most likely to contain two dimers in the asymmetric unit, with a VM value of 3.32 Å3 Da−1. Diffraction data were collected at 2.2 Å resolution using synchrotron radiation at beamline BL26B1 of SPring-8, Japan

  4. Sub-nephrotoxic cisplatin sensitizes rats to acute renal failure and increases urinary excretion of fumarylacetoacetase.

    Vicente-Vicente, Laura; Sánchez-Juanes, Fernando; García-Sánchez, Omar; Blanco-Gozalo, Víctor; Pescador, Moisés; Sevilla, María A; González-Buitrago, José Manuel; López-Hernández, Francisco J; López-Novoa, José Miguel; Morales, Ana Isabel


    Nephrotoxicity limits the therapeutic efficacy of the antineoplastic drug cisplatin. Due to dosage adjustment and appropriate monitoring, most therapeutic courses with cisplatin produce no or minimal kidney damage. However, we studied whether even sub-nephrotoxic dosage of cisplatin poses a potential risk for the kidneys by predisposing to acute kidney injury (AKI), specifically by lowering the toxicity threshold for a second nephrotoxin. With this purpose rats were treated with a single sub-nephrotoxic dosage of cisplatin (3mg/kg, i.p.) and after two days, with a sub-nephrotoxic regime of gentamicin (50mg/kg/day, during 6 days, i.p.). Control groups received only one of the drugs or the vehicle. Renal function and renal histology were monitored throughout the experiment. Cisplatin treatment did not cause any relevant functional or histological alterations in the kidneys. Rats treated with cisplatin and gentamicin, but not those under single treatments, developed an overt renal failure characterized by both renal dysfunction and massive tubular necrosis. In addition, the urinary excretion of fumarylacetoacetase was increased in cisplatin-treated animals at subtoxic doses, which might be exploited as a cisplatin-induced predisposition marker. In fact, the urinary level of fumarylacetoacetase prior to the second nephrotoxin correlated with the level of AKI triggered by gentamicin in predisposed animals. PMID:25677510

  6. Oral HPV infection and MHC class II deficiency (A study of two cases with atypical outcome

    Guirat-Dhouib Naouel


    Full Text Available Abstract Background Major histocompatibility complex class II deficiency, also referred to as bare lymphocyte syndrome is a rare primary Immunodeficiency disorder characterized by a profondly deficient human leukocyte antigen class II expression and a lack of cellular and humoral immune responses to foreign antigens. Clinical manifestations include extreme susceptibility to viral, bacterial, and fungal infections. The infections begin in the first year of life and involve usually the respiratory system and the gastrointestinal tract. Severe malabsorption with failure to thrive ensues, often leading to death in early childhood. Bone marrow transplantation is the curative treatment. Case reports Here we report two cases with a late outcome MHC class II deficiency. They had a long term history of recurrent bronchopulmonary and gastrointestinal infections. Bone marrow transplantation could not be performed because no compatible donor had been identified. At the age of 12 years, they developed oral papillomatous lesions related to HPV (human papillomavirus. The diagnosis of HPV infection was done by histological examination. HPV typing performed on the tissue obtained at biopsy showed HPV type 6. The lesions were partially removed after two months of laser treatment. Conclusions Viral infections are common in patients with MHC class II and remain the main cause of death. Besides warts caused by HPV infection do not exhibit a propensity for malignant transformation; they can cause great psychosocial morbidity.

  8. Atypical Toxicity Associated with 5-Fluororacil in a DPD-Deficient Patient with Pancreatic Cancer. Is Ethnicity a Risk Factor?

    Muhammad Wasif Saif


    Full Text Available Context Fluoropyrimidines constitute the backbone of chemotherapy regimens for GI tumors, including pancreatic cancer where it is used either as a radiosensitizer or as second-line after failing gemcitabine. While normal dihydropyrimidine dehydrogenase (DPD enzyme activity is rate limiting in 5- fluorouracil (5-FU catabolism, its deficiency could increase concentrations of bioavailable 5-FU anabolic products leading to 5-FU related toxicity syndrome. The most common toxicities include myelosuppression, stomatitis, neuropathy, and diarrhea. The prevalence of this autosommal codominently inherited pharmacogenetic syndrome is approximately 3-5% in the Caucasian population and 8% in the African-American population. Case report We present here a case of an African-American patient with pancreatic cancer who developed a desquamative skin rash on the face, trunk, and forearms as the worst rash (grade 3 following 5-FU bolus that led to the investigation of DPD enzyme. Measurement of DPD activity by radioisotopic assay methods described previously revealed an abnormally low level of 0.087 nmol/min/mg protein (reference range: 0.182-0.688 nmol/min/mg protein. She was treated toxicity with intravenous steroids and antihistamine therapy. Further 5- FU therapy was discontinued. Conclusions This case suggest that the pattern of toxicities associated with 5-FU can vary, especially in patients with different ethnic backgrounds (whites versus nonwhites. These findings become of further importance as our recent study suggests that DPD deficiency may be more common among African-Americans.

  9. Atypical Depression

    Erhan Ertekin


    Full Text Available Atypical depression is defined as a specifier of major depressive disorder. Columbia criteria for atypical depression are commonly used to make a diagnosis. Female sex, onset at early age, chronic course, and higher rate of comorbidity (especially anxiety disorder and bipolar disorder is noteworthy in atypical depression. Although, the atypical depression seems to support the familial genetic transition, there is not any specific study supporting these data. In the treatment of atypical depression, monoamine oxidase inhibitors are reported to be more effective than tricyclic antidepressants. In recent studies, selective serotonin reuptake inhibitors have also proven to be efficient.

  11. Osteogenesis imperfecta: an atypical association

    Snehal Mallakmir


    Full Text Available Osteogenesis Imperfecta (OI also known as and lsquo;brittle bone disease', is a clinically heterogeneous connective tissue disorder with defect in type I collagen. The more prevalent autosomal dominant forms of OI are caused by primary defects in type I collagen, while autosomal recessive forms are caused by deficiency of proteins which interact with type I procollagen for post-translational modification and/or folding. Few cases of OI associated with atypical features have been reported. We report a case of 54 days male child of OI associated with pyloric stenosis. The case probably is a form of autosomal recessive OI with severe phenotype. [Int J Res Med Sci 2015; 3(3.000: 783-785

  13. Dengue fever: atypical manifestation

    Nataraj Gangasiddaiah


    Full Text Available Dengue fever is affecting millions of population globally. For the past one decade, we have seen several outbreaks and even causing significant mortality of affected population. We witnessed numerous pattern and multisystem presentation of dengue in this period. The CNS manifestation like encephalitis, polyneuropathy (GB like syndrome and paresthesias were uncommonly reported priorly. Pancreatitis, polyserositis, carditis of varying severity and hepatic failure are the, some of atypical manifestations observed in recent out breaks. So dengue illness can presents with multi system involvement and can account to significant mortality. Here an attempt was done to present varying, uncommon and atypical manifestation of dengue illness. [Int J Res Med Sci 2014; 2(4.000: 1804-1806

  14. Endocervical Atypical Polypoid Adenomyoma.

    Protopapas, Athanasios; Sotiropoulou, Maria; Athanasiou, Stavros; Loutradis, Dimitrios


    Atypical polypoid adenomyomas (APAMs) are rare uterine tumors that occur predominantly in premenopausal women, with less than 250 cases reported so far, worldwide. They may recur after treatment, and they may coexist with, or precede development of an endometrial adenocarcinoma. For this reason cases managed with conservative surgery or medical therapies require long-term follow-up. We report the case of a 41 years old nulliparous patient who during a diagnostic hysteroscopy was found with an endocervical atypical polypoid adenomyoma (APAM). The patient was desirous of a pregnancy, reported menometrorrhagia, and had a coexistent 5 cm, grade 2, submucous myoma, 3 endometrial polyps, and diffuse adenomyosis. She was treated with hysteroscopic resection of the APAM and polyps, plus laparoscopic myomectomy and wedge resection of adenomyosis. She is on an IVF list and after 4 months she is symptoms-free.

    Bisphosphonates (BPs) represent the most widely used therapy for osteoporosis. Recently, a relationship between long-term treatment with BPs and a subset of atypical femoral fractures (AFFs) from below the lesser trochanter to the sovracondilar line has been described. Many etiopathogenetic theories have been invoked to explain AFFs: reduced bone turnover and increased osteoblast bone apposition with accumulation of microdamage and decreased bone toughness with subsequent increased risk of mi...

  16. Conns' syndrome - atypical presentations

    Primary hyperaldosteronism (Conns' syndrome) commonly presents with a combination of clinical features of hypokalemia and hypertension. Atypical presentations like normotension, normokalemia and neurological ailments are described in few cases. We encountered two such cases, the first presenting with acute neurological complaint and second case having insignificant hypertension. Both the patients had a characteristic biochemical and imaging profile consistent with primary hyperaldosteronism and responded to surgical resection of adrenal adenoma. (author)

  17. Dermatofibroma: Atypical presentations

    Mousumi Roy Bandyopadhyay


    Full Text Available Dermatofibroma is a common benign fibrohistiocytic tumor and its diagnosis is easy when it presents classical clinicopathological features. However, a dermatofibroma may show a wide variety of clinicopathological variants and, therefore, the diagnosis may be difficult. The typical dermatofibroma generally occurs as a single or multiple firm reddish-brown nodules. We report here two atypical presentations of dermatofibroma - Atrophic dermatofibroma and keloidal presentation of dermatofibroma. Clinical dermal atrophy is a common phenomenon in dermatofibromas as demonstrated by the dimpling on lateral pressure. However, this feature is exaggerated in the atrophic variant of dermatofibroma. Atrophic dermatofibroma is defined by dermal atrophy of more than 50% of the lesion apart from the usual features of common dermatofibroma. The keloidal variant of dermatofibroma should not be overlooked as a simple keloid. The findings of keloidal change in dermatofibromas may support that trauma is a possible cause of dermatofibroma.

  19. A Rare Case: Atypical Measles

    Ümmü Sena Sarı


    Full Text Available Atypical measles has been described in persons who were exposed to wild measles virus several years after they were immunized with killed measles vaccine. Occasionally, it can be caused by live measles vaccines also. It is a clinical picture different from typical measles. In this report, an adult patient with a history of immunization, who presented with high fever, maculopapular rash starting at the palms and soles, and pneumonia, is presented. Atypical measles that was first reported in the 1970s in mostly kids should be considered for differential diagnosis in adult cases presenting with high fever, atypical rash and pneumonia even if patients have a history of immunization

  20. Atypical Celiac Disease: From Recognizing to Managing

    B. Admou


    Full Text Available The nonclassic clinical presentation of celiac disease (CD becomes increasingly common in physician’s daily practice, which requires an awareness of its many clinical faces with atypical, silent, and latent forms. Besides the common genetic background (HLA DQ2/DQ8 of the disease, other non-HLA genes are now notably reported with a probable association to atypical forms. The availability of high-sensitive and specific serologic tests such as antitissue transglutuminase, antiendomysium, and more recent antideamidated, gliadin peptide antibodies permits to efficiently uncover a large portion of the submerged CD iceberg, including individuals having conditions associated with a high risk of developing CD (type 1 diabetes, autoimmune diseases, Down syndrome, family history of CD, etc., biologic abnormalities (iron deficiency anemia, abnormal transaminase levels, etc., and extraintestinal symptoms (short stature, neuropsychiatric disorders, alopecia, dental enamel hypoplasia, recurrent aphtous stomatitis, etc.. Despite the therapeutic alternatives currently in developing, the strict adherence to a GFD remains the only effective and safe therapy for CD.

    We present an atypical case of familial benign pemphigus (Hailey-Hailey disease), which presented as crusted, annular plaques limited to the back without intertriginous involvement. We could not find in the literature another patient with plaques located solely on the back without a prior history of classical disease.

  3. Recognition and diagnosis of atypical depression.

    Thase, Michael E


    The term atypical depression dates to the first wave of reports describing differential response to monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants (TCAs). In contrast to more TCA-responsive depressions, patients with so-called atypical symptoms (e.g., hypersomnia, interpersonal sensitivity, leaden paralysis, increased appetite and/or weight, and phobic anxiety) were observed to be more responsive to MAOIs. After several decades of controversy and debate, the phrase "with atypical features" was added as an episode specifier in the DSM-IV in 1994. The 1-year prevalence of the defined atypical depression subtype is approximately 1% to 4%; around 15% to 29% of patients with major depressive disorder have atypical depression. Hardly "atypical" in contemporary contexts, atypical depression also is common in dysthymic bipolar II disorders and is notable for its early age at onset, more chronic course, and high rates of comorbidity with social phobia and panic disorder with agoraphobia. The requirement of preserved mood reactivity is arguably the most controversial of the DSM-IV criteria for atypical depression. When compared with melancholia, the neurobiological profiles of patients with atypical depression are relatively normal. The utility of the atypical depression subtype for differential therapeutics diminished substantially when the TCAs were supplanted as first-line antidepressants by the selective serotonin reuptake inhibitors. Although introduction of safer MAOIs has fostered renewed interest in atypical depression, the validity and importance of the DSM-IV definition of atypical depression for the nosology of affective illness remains an open question.

  4. Atypical fractures, a biased perspective.

    Aspenberg, Per


    When stress fractures started to show up in the femurs of elderly ladies, it was soon evident that bisphosphonate use lay behind, and the absolute risk increase due to bisphosphonate use was reasonably well estimated already in 2008. Thereafter followed a period of confusion: the term atypical fracture was introduced, with a definition so vague that the true stress fractures tended to disappear in a cloud of ambiguity. This cast doubt on the association with bisphosphonates. The association was then re-established by large epidemiological studies based on radiographic adjudication. Atypical fractures are largely caused by bisphosphonates. With a correct indication, bisphosphonates prevent many more fractures than they cause, at least during the first years of use. With an incorrect indication they are likely to cause more harm than good. PMID:26768286

    Koranne R


    Full Text Available A study of 36 untreated patients with early syphilis revealed atypical variations namely; long incubation period of 101 days in I patient, more than 3 chancres in 1, undermined margin of the chancre along with tenderness in 1 and moderate to severe tenderness of the ulcers in 2 cases. In 3 patients there was no indurations of the ulcers. Three patients with primary syphilis had unilateral lymphadenitis, and in I case the lymph nodes were not only tender but showed tendency towardsmatingawell. Insecondarysyphilis, 11 out of 16 patients having condylomata lata had no other muco-cutaneous lesions. Concomitant presence of other venereal disease to account for the atypical manifestations was discounted- by appropriate laboratory tests, response to therapeutic agents and follow up.

  7. [Vitamin B12 deficiency in the elderly].

    Leischker, A H; Kolb, G F


    The prevalence of vitamin B12 deficiency increases with age. Patients with dementia and spouses of patients with dementia are at special risk for the development of vitamin B12 deficiency. In a normal diet this vitamin is present only in animal source foods; therefore, vegans frequently develop vitamin B12 deficiency if not using supplements or foods fortified with cobalamin. Apart from dementia, most of these manifestations are completely reversible under correct therapy; therefore it is crucial to identify and to treat even atypical presentations of vitamin B12 deficiency as early as possible. This article deals with the physiology and pathophysiology of vitamin B12 metabolism. A practice-oriented algorithm which also considers health economic aspects for a rational laboratory diagnosis of vitamin B12 deficiency is presented. In cases with severe neurological symptoms, therapy should be parenteral, especially initially. For parenteral treatment, hydroxocobalamin is the drug of choice. PMID:25586321

  8. Evolving A-Type Artificial Neural Networks

    Orr, Ewan


    We investigate Turing's notion of an A-type artificial neural network. We study a refinement of Turing's original idea, motivated by work of Teuscher, Bull, Preen and Copeland. Our A-types can process binary data by accepting and outputting sequences of binary vectors; hence we can associate a function to an A-type, and we say the A-type {\\em represents} the function. There are two modes of data processing: clamped and sequential. We describe an evolutionary algorithm, involving graph-theoretic manipulations of A-types, which searches for A-types representing a given function. The algorithm uses both mutation and crossover operators. We implemented the algorithm and applied it to three benchmark tasks. We found that the algorithm performed much better than a random search. For two out of the three tasks, the algorithm with crossover performed better than a mutation-only version.

  11. Atypical parkinsonism: diagnosis and treatment.

    Stamelou, Maria; Bhatia, Kailash P


    Atypical parkinsonism comprises typically progressive supranuclear palsy, corticobasal degeneration, and mutilple system atrophy, which are distinct pathologic entities; despite ongoing research, their cause and pathophysiology are still unknown, and there are no biomarkers or effective treatments available. The expanding phenotypic spectrum of these disorders as well as the expanding pathologic spectrum of their classic phenotypes makes the early differential diagnosis challenging for the clinician. Here, clinical features and investigations that may help to diagnose these conditions and the existing limited treatment options are discussed. PMID:25432722

  12. Atypical Manifestation of Vestibular Schwannoma

    Webster, Guilherme


    Full Text Available Introduction: Vestibular schwannoma (also known as acoustic neuroma is a benign tumor whose cells are derived from Schwann sheaths, which commonly occurs from the vestibular portion of the eighth cranial nerve. Furthermore, vestibular schwannomas account for ∼8% of intracranial tumors in adults and 80 to 90% of tumors of the cerebellopontine angle. Its symptoms are varied, but what stands out most is a unilateral sensorineural hearing loss, with a low index of speech recognition. Objective: Describe an atypical manifestation of vestibular schwannoma. Case Report: The 46-year-old woman had vertigo and binaural hearing loss and fullness, with ear, nose, and throat examination suggestive of cochlear injury. After 6 months, the patient developed worsening of symptoms and onset of right unilateral tinnitus. In further exams the signs of cochlear damage remained, except for the vestibular test (hyporeflexia. Magnetic resonance imaging showed an expansive lesion in the right cerebellopontine angle. Discussion: This report warns about the atypical manifestations of vestibular schwannoma, which must always be remembered in investigating and diagnosing hearing loss.

    Full Text Available Aim: To review the experience with the diagnosis and management of extragonadal germ cell tumors (GCT with a subset analysis of those with atypical features. Materials and Methods: A retrospective chart review of patients of extragonadal germ cell tumors between 2000 and 2010 was carried out. Results: Fifteen children aged 7 days to 15 years (median, 1.5 years were included. Three had an antenatal diagnosis (one sacrococcygeal, one retrobulbar, one retroperitoneal tumor and were operated in the neonatal period. The locations were distributed between the retrobulbar area (1, anterior neck-thyroid gland (1, mediastinum (4, abdominothoracic extending through the esophageal hiatus (1, retroperitoneal (4 and sacrococcygeal (4. On histological examination, five harbored immature elements while two were malignant; the latter children received postexcision adjuvant chemotherapy. There was no mortality. At a median follow-up of 4.5 years (6 months to 8 years, 14/15 have had an event-free survival. One immature mediastinal teratoma that recurred locally 7.5 years after the initial operation was excised and adjuvant chemotherapy instituted. Conclusions: Extragonadal GCTs in children are uncommon and occasionally present with atypical clinical, radiological and histological features resulting in diagnostic and therapeutic dilemmas.

  14. Typical and atypical AIS. Pathogenesis.

    Dudin, M; Pinchuk, D


    AIS hypothesis has the right to recognition, if it explains the transition of "healthy" vertebra column into status of "scoliotic" one. AIS is the most investigated disease in the history of orthopedics, but up the present time there is no clear explanation of some its phenomena: vertebra column mono-form deformation along with its poly etiology character, interrelation of its origin and development and child's growth process etc. The key for authors' view at AIS was scoliosis with non-standard (concave side) rotation. On the bases of its' multifunctional instrumental investigation results (Rtg, EMG, EEG, optical topography, hormonal and neuropeptides trials, thermo-vision methods and other) in comparison with typical AIS was worked out the new hypothesis, part of it is suggested for discussion. In the work under observation is the sequence of appearance of typical and atypical scoliosis symptomatology beginning from the preclinical stage. PMID:22744477

    Full Text Available Mental illness constitutes the second-largest disease burden in the United States. Psychosis is one of the most common and severe mental illnesses. It is an extremely devastating condition characterised by delusions, hallucinations, distortion of thoughts and deteriorating social functioning experiences. Psychosis in all human societies has approximately same incidence of occurrence as in accordance to “anthropo-parity principle.” It has large economic impact on various aspects of cognition, health, and quality of life which has devastated effects on its sufferers and facing them large economic burden. Psychosis (Schizophrenia is associated with an imbalance of the dopaminergic system, entailing hyper-stimulation of dopamine function in the brain, particularly in the mesolimbic pathway. Consequences of antipsychotic treatment are far reaching and expensive. Detrimental extrapyramidal side effects associated with conventional antipsychotics and non-compliance among patients limits long term treatment with conventional antipsychotics. It gives rise to a new class, atypical antipsychotics owning low propensity to cause EPS, efficacy against refractory cases and better control over negative symptoms, better tolerance and compliance along with lower relapse rate and safer adverse effect profile. Atypical antipsychotics have revolutionized the treatment of psychosis, now being the treatment of choice for patients with psychosis. The positive therapeutic experience with the atypical antipsychotics in the treatment of psychosis and their favourable effects outweighs their unfavourable adverse effects. Though atypical antipsychotics are widely prescribed in the treatment of schizophrenia, however not a single atypical antipsychotic drug having any exceptional efficacy and safety profile. Thus, there is still a lot of research needed to be carried out in the development of novel atypical antipsychotics. This review is comprehensive appraisal about

  19. Surgical Options for Atypical Facial Pain Syndromes.

    Rahimpour, Shervin; Lad, Shivanand P


    Atypical neuropathic facial pain is a syndrome of intractable and unremitting facial pain that is secondary to nociceptive signaling in the trigeminal system. These syndromes are often recalcitrant to pharmacotherapy and other common interventions, including microvascular decompression and percutaneous procedures. Herein, the authors present two other viable approaches (nucleus caudalis dorsal root entry zone lesioning and motor cortex stimulation), their indications, and finally a possible treatment algorithm to consider when assessing patients with atypical facial pain.

  20. Interventional trials in atypical parkinsonism.

    Eschlböck, S; Krismer, F; Wenning, G K


    Atypical parkinson disorders (APD) are rapidly progressive neurodegenerative diseases with a variable clinical presentation that may even mimic Parkinson's disease. Multiple system atrophy (MSA), progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) are commonly summarized under this umbrella term. Significant developments in research have expanded knowledge and have broadened available symptomatic treatments, particularly for the treatment of neurogenic orthostatic hypotension. Nonetheless, symptomatic support still remains limited in all of these disorders. Currently, there exists no effective treatment to delay disease progression and disease-modifying trials have failed to provide coherent and convincing results. Recent trials of rasagiline (in MSA), rifampicin (in MSA), tideglusib (in PSP) and davunetide (in PSP) reported negative results. Nevertheless, large cohorts of patients were recruited for interventional studies in the last few years which improved our understanding of trial methodology in APDs immensely. In addition, remarkable progress in basic research has been reported recently and will provide a solid foundation for future therapeutic trials. In this review, we will summarize published randomized, placebo-controlled clinical trials (RCTs) in APDs. Additionally, the design of ongoing and unpublished interventions will be presented.

  1. Atypical presentations of neuromyelitis optica

    Douglas Sato


    Full Text Available Neuromyelitis optica (NMO is an inflammatory disease of central nervous system classically characterized by acute, severe episodes of optic neuritis and longitudinally extensive transverse myelitis, usually with a relapsing course. The identification of an autoantibody exclusively detected in NMO patients against aquaporin-4 (AQP-4 has allowed identification of cases beyond the classical phenotype. Brain lesions, once thought as infrequent, can be observed in NMO patients, but lesions have different characteristics from the ones seen in multiple sclerosis. Additionally, some AQP-4 antibody positive patients may present with a variety of symptoms not being restricted to optic neuritis and acute myelitis during the first attack or in a relapse. Examples are not limited to, but may include patients only with brain and/or brainstem lesions, narcolepsy with hypothalamic lesions or patients with intractable hiccups, nausea and vomiting. The prompt identification of NMO patients with atypical presentations may benefit these patients with institution of early treatment to reduce disability and prevent further attacks.

  2. Negative symptoms presenting as neuropsychiatric manifestation of vitamin B12 deficiency

    Sahoo, Manoj Kumar; Avasthi, Ajit; Singh, Parampreet


    Long lists of psychiatric illness or symptoms have been documented to be caused by vitamin B12 deficiency. We describe an atypical case of a young adult who presented with predominant negative symptoms followed by neurological symptoms consistent with vitamin B12 deficiency. The symptoms showed complete remission after vitamin B12 supplementation. The uniqueness of this case is that vitamin B12 deficiency presented with predominant negative symptoms without other psychotic and manic symptoms,...

  3. [Approaches to vitamin B12 deficiency].

    Russcher, Henk; Heil, Sandra G; Slobbe, Lennert; Lindemans, Jan


    A 28-year-old female vegetarian was referred to a specialist in internal medicine with persistent iron deficiency. Laboratory analysis revealed microcytic anaemia with low ferritin levels but normal total vitamin B12 levels. The red blood cell distribution width, however, showed a very wide variation in red blood cell sizes, indicating a coexisting vitamin B12 deficiency, which was confirmed by the low concentration of active vitamin B12. Another patient, a 69-year-old woman with a history of previous gastric surgery and renal insufficiency as a complication of diabetes mellitus, was suspected to be deficient in vitamin B12, as she had low total vitamin B12 levels and an accumulation of methylmalonic acid and homocysteine in her blood. Testing the total concentration of vitamin B12 alone has insufficient diagnostic accuracy and no accepted gold standard is available for diagnosing vitamin B12 deficiency. With the development of newer tests, such as measuring holotranscobalamin II (concentration of active vitamin B12), atypical and subclinical deficiency states can be recognized. A new approach to diagnosing vitamin B12 deficiency is presented, based upon these 2 case descriptions. PMID:22217304

  4. Clinical Presentation of Atypical Genital Herpes

    李俊杰; 梁沛杨; 罗北京


    Objective: To make a clinical analysis on the basis of 36cases of atypical genital herpes (GH) patients. Methods: Thirty-six cases of atypical GH were diagnosedclinically, and their case histories, symptoms and signs wererecorded in detail and followed up. Polymerase chain reaction(PCR) was adopted for testing HSV2-DNA with cotton-tippedswabs. Enzyme-linked immuno sorbent assay (ELISA) forserum anti-HSV2-IgM was done to establish a definfiivediagnosis. Other diagnoses were excluded at the same time bytesting for related pathogens including fungi, Chlamydia,Mycoplasma, Treponema pallidum, gonococci, Trichomonas,etc. Results: The main clinical manifestations of atypical GHwere: (1) small genital ulcers; (2) inflammation of urethralmeatus; (3) nonspecific genital erythema; (4) papuloid noduleson the glands; (5) nonspecific vaginitis. Twenty-three cases(64%) tested by PCR were HSV2-DNA sera-positive, and 36cases (100 %) anti-HSV2-IgM sera-positive by ELISA. Conclusion: atypical HSV is difficult to be diagnosed. Butthe combination of PCR and ELIAS will be helpful to thediagnosis of atypical HSV.

  7. Atypical microbial infections of digestive tract may contribute to diarrhea in mucopolysaccharidosis patients: a MPS I case study

    Jakóbkiewicz-Banecka Joanna


    Full Text Available Abstract Background Mucopolysaccharidoses are heritable, metabolic diseases caused by deficiency in an activity of one of specific lysosomal enzymes involved in degradation of mucoplysaccharides (glycosaminoglycans. Among many medical problems of patients with mucopolysaccharidoses, there are frequent episodes of diarrhea of unknown etiology. Case presentation A girl, diagnosed enzymatically for mucopolysaccharidosis type I (deficiency of α-L-iduronidase at the age of 3 years and 9 months, was investigated until the age of 5 years and 4 months. Frequent loose stools and episodes of diarrhea, often accompanied by vomiting, were encountered. Detailed microbiological analyses were performed and atypical microbial infections (most often enetropathogenic Escherichia coli, but also other species, like Pseudomonas aeruginosa or Staphylococcus aureus, as well as adenoviruses of the digestive tract were found in most severe diarrhea episodes. Often, isolations of pathogenic bacterial strains from stools of the investigated patient suffering from diarrhea were not obvious during the first screening, and only detailed microbiological studies, including re-isolation of colonies, gave the results of isolation of particular pathogenic strains (especially in the case of enetropathogenic E. coli. Conclusion We conclude that atypical microbial infections of digestive tract may contribute significantly to diarrhea in mucopolysaccaridosis patients. Since isolated strains were not typical and their isolation was often possible only after detailed investigation (not during a standard screening, such atypical microbial infections of digestive tract of mucopolysaccharidosis patients could be usually overlooked to date. Importantly, these atypical infections could be effectively treated with antimicrobial agents.

  17. Cohort study of atypical pressure ulcers development.

    Jaul, Efraim


    Atypical pressure ulcers (APU) are distinguished from common pressure ulcers (PU) with both unusual location and different aetiology. The occurrence and attempts to characterise APU remain unrecognised. The purpose of this cohort study was to analyse the occurrence of atypical location and the circumstances of the causation, and draw attention to the prevention and treatment by a multidisciplinary team. The cohort study spanned three and a half years totalling 174 patients. The unit incorporates two weekly combined staff meetings. One concentrates on wound assessment with treatment decisions made by the physician and nurse, and the other, a multidisciplinary team reviewing all patients and coordinating treatment. The main finding of this study identified APU occurrence rate of 21% within acquired PU over a three and a half year period. Severe spasticity constituted the largest group in this study and the most difficult to cure wounds, located in medial aspects of knees, elbows and palms. Medical devices caused the second largest occurrence of atypical wounds, located in the nape of the neck, penis and nostrils. Bony deformities were the third recognisable atypical wound group located in shoulder blades and upper spine. These three categories are definable and time observable. APU are important to be recognisable, and can be healed as well as being prevented. The prominent role of the multidisciplinary team is primary in identification, prevention and treatment.

    Mittal R


    Full Text Available One 8 year female child had asymptomatic, anaesthetic, hypohidrotic, atrophic, yellowish, waxy plaque on the front of left thigh since 2 months. No nerve thickening was observed clinically or histopathologically. Hyperkeratosis, follicular keratosis, epidermal atrophy, degeneration of collagen, mononuclear granulomas and perivascular mononuclear infiltrate confirmed the clinical diagnosis of atypical necrobiosis lipoidica.

  19. Psychiatric syndromes associated with atypical chest pain

    Nikolić Gordana


    Full Text Available Background/Aim. Chest pain often indicates coronary disease, but in 25% of patients there is no evidence of ischemic heart disease using standard diagnostic tests. Beside that, cardiologic examinations are repeated several times for months. If other medical causes could not be found, there is a possibility that chest pain is a symptom of psychiatric disorder. The aim of this study was to determine the presence of psychiatric syndromes, increased somatization, anxiety, stress life events exposure and characteristic of chest pain expression in persons with atypical chest pain and coronary patients, as well as to define predictive parameters for atypical chest pain. Method. We compared 30 patients with atypical chest pain (E group to 30 coronary patients (K group, after cardiological and psychiatric evaluation. We have applied: Mini International Neuropsychiatric Interview (MINI, The Symptom Checklist 90-R (SCL-90 R, Beck Anxiety Inventory (BAI, Holms-Rahe Scale of stress life events (H-R, Questionnaire for pain expression Pain-O-Meter (POM. Significant differences between groups and predictive value of the parameters for atypical chest pain were determined. Results. The E group participants compared to the group K were younger (33.4 ± 5.4 : 48.3 ± 6,4 years, p < 0.001, had a moderate anxiety level (20.4 ± 11.9 : 9.6 ± 3.8, p < 0.001, panic and somatiform disorders were present in the half of the E group, as well as eleveted somatization score (SOM ≥ 63 -50% : 10%, p < 0.01 and a higher H-R score level (102.0 ± 52.2 : 46.5 ± 55.0, p < 0.001. Pain was mild, accompanied with panic. The half of the E group subjects had somatoform and panic disorders. Conclusion. Somatoform and panic disorders are associated with atypical chest pain. Pain expression is mild, accompained with panic. Predictive factors for atypical chest pain are: age under 40, anxiety level > 20, somatization ≥ 63, presence of panic and somatoform disorders, H-R score > 102

  3. An atypical presentation of antiphospholipid antibody syndrome

    Deepti D′Souza


    Full Text Available Cutaneous manifestations in antiphospholipid antibody syndrome (APS though common, are extremely diverse and it is important to know which dermatological finding should prompt consideration of antiphospholipid syndrome. The cutaneous manifestations of APS vary from livedo reticularis to cutaneous necrosis, and systemic involvement is invariably an accomplice in APS. Cutaneous ulcers with sharp margins can be seen in APS and they are usually seen on the legs. This case had an atypical presentation, as the initial presentation was painful necrotic ulcers over the legs, which resembled pyoderma gangrenosum and she had no systemic manifestations. There was no history of any arterial or venous thrombosis or any abortions. Antiphospholipid syndrome can be tricky to diagnose when cutaneous lesions are atypical. Nonetheless, it is very important to pin down this syndrome early due to its systemic complications.

    Coulier, B.; Cloots, V. [Department of Diagnostic Imaging, Cliniques St. Luc, Rue St Luc 8, 5004, Bouge, Namur (Belgium)


    We report two rare cases of iliopsoas bursitis extending into the retroperitoneal space. The first lesion contained much gas, mimicking a retroperitoneal abscess, and the second was responsible for atypical inguinal pain. The diagnosis was made by contrast-enhanced CT in both cases and arthrography in the first case. Iliopsoas bursitis in these two patients, it is hypothesized, extended into the retroperitoneum, at least in part, by way of intraneural or perineural structures. (orig.)

    Full Text Available Ryosuke Kawamura1,2, Hidenao Ideta1, Hideyuki Hori1, Kenya Yuki2, Tsuyoshi Uno1, Tatsurou Tanabe1, Kazuo Tsubota2, Tsutomu Kawasaki11Ideta Eye Hospital, Kumamoto, Japan; 2Keio University, School of Medicine, Department of Ophthalmology, Tokyo, JapanBackground: Central serous chorioretinopathy (CSC has been traditionally treated with laser photocoagulation. We thought that transpupillary thermotherapy (TTT utilizing a lower temperature than that of conventional laser photocoagulation might minimize permanent retinal and choroidal damage. Studies suggest that undesirable effects on vision due to TTT are minimal even if it is applied to foveal and/or parafoveal lesions when TTT requires a larger irradiation spot. The aim of this study was to evaluate the efficacy of TTT in the management of atypical CSC.Methods: We defined atypical CSC as bullous retinal detachment with diffuse or several leakages, severe leakage with fibrin formation under serous retinal detachment, or leakage within a pigment epithelium detachment. Eight consecutive patients with atypical CSC underwent visual acuity testing, ophthalmic examination, color photography, fluorescein angiography, and optical coherence tomography to evaluate the results of transpupillary thermotherapy. Retreatment of atypical CSC was based on ophthalmic examination, optical coherence tomography, and fluorescein angiography. TTT was performed on the leaking spots shown in fluorescein angiography, with a power of 50–250 mW, spot size of 500–1200 µm, and exposure time of 13–60 seconds to minimize retinal damage.Results: In five of eight affected eyes, serous detachments completely resolved within 1 month after the initial TTT. One eye had persistent subretinal fluid and required a second TTT treatment. Two eyes showed no resolution of CSC and were treated by conventional photocoagulation. Initial best-corrected visual acuity (BCVA ranged from 20/600 to 20/20 (mean, 20/40; median, 20/30. Final BCVA

  11. Characterization of the atypical lymphocytes in African swine fever

    Karalyan, Z. A.; Ter-Pogossyan, Z. R.; Abroyan, L. O.; Hakobyan, L. H.; Avetisyan, A. S.; Yu, Karalyan N.; Karalova, E. M.


    Aim: Atypical lymphocytes usually described as lymphocytes with altered shape, increased DNA amount, and larger size. For analysis of cause of genesis and source of atypical lymphocytes during African swine fever virus (ASFV) infection, bone marrow, peripheral blood, and in vitro model were investigated. Materials and Methods: Atypical lymphocytes under the influence of ASFV were studied for morphologic, cytophotometric, and membrane surface marker characteristics and were used in vivo and in vitro models. Results: This study indicated the increased size, high metabolic activity, and the presence of additional DNA amount in atypical lymphocytes caused by ASFV infection. Furthermore, in atypical lymphocytes, nuclear-cytoplasmic ratio usually decreased, compared to normal lymphocytes. In morphology, they looking like lymphocytes transformed into blasts by exposure to mitogens or antigens in vitro. They vary in morphologic detail, but most of them are CD2 positive. Conclusions: Our data suggest that atypical lymphocytes may represent an unusual and specific cellular response to ASFV infection. PMID:27536044

  12. Management of Typical and Atypical Hangman's Fractures

    Al-Mahfoudh, Rafid; Beagrie, Christopher; Woolley, Ele; Zakaria, Rasheed; Radon, Mark; Clark, Simon; Pillay, Robin; Wilby, Martin


    Study Design Retrospective study of a prospectively maintained database. Objective Our aim was to retrospectively review management and outcomes of patients with low-grade hangman's fractures, specifically looking at differences in outcomes between collars and halo immobilization. We also studied fracture patterns and their treatment outcomes. Methods Forty-one patients with hangman's fractures were identified from 105 patients with axis fractures between 2007 and 2013. Typical hangman's fractures were defined as traumatic spondylolisthesis of the axis causing a bilateral pars interarticularis fracture. Fractures involving the posterior cortex of C2 on one or both sides or an asymmetrical pattern were defined as atypical. Results There were 41 patients with a mean age of 59 years, with 13 (31.7%) typical and 28 (68.2%) atypical fractures. There were 22 (53.6%) type 1 fractures, 7 (41.4%) type 2 fractures, and 2 (4.9%) type 2a fractures in this series. Cervical collars were used to manage 11 patients (27% of all patients with hangman's fractures) and halo orthosis was used in 27 (65.8%). Three (7.3%) patients underwent surgical fixation of the fracture. Bony union was achieved in all patients on radiologic follow-up. Permanent neurologic deficit occurred in one patient due to associated injuries. Neck pain and stiffness were reported more commonly in the atypical group, but this finding was not statistically significant. Conclusions The majority of hangman type fractures can be treated nonoperatively. We found no difference in outcomes between a rigid collar or halo immobilization for treatment of low-grade fractures. Radiologic follow-up is essential to identify cases of nonunion. PMID:27099816

  13. Hematological Side Effects of Atypical Antipsychotic Drugs

    Serap Erdogan


    Full Text Available Atypical antipsychotics cause less frequently extrapyramidal system symptoms, neuroleptic malignant syndrome and hyperprolactinemia than typical antipsychotics. However hematological side effects such as leukopenia and neutropenia could occur during treatment with atypical antipsychotics. These side effects could lead to life threatening situations and the mortality rate due to drug related agranulocytosis is about 5-10%. There are several hypothesis describing the mechanisms underlying drug induced leukopenia and/or neutropenia such as direct toxic effects of these drugs upon the bone marrow or myeloid precursors, immunologic destruction of the granulocytes or supression of the granulopoiesis. Clozapine is the antipsychotic agent which has been most commonly associated with agranulocytosis. A nitrenium ion which is formed by the bioactivation of clozapine is thought to have an important role in the pathophysiogy of this adverse effect. Aside from clozapine, there are several case reports reporting an association between olanzapine, quetiapine, risperidone, ziprasidone, aripiprazole and leukopenia. We did not find any study or case report presenting amisulpride or sulpride related hematological side effects in our literature search. Patients who had hematological side effects during their previous antipsychotic drug treatments and who had lower baseline blood leukocyte counts, have higher risk to develop leukopenia or neutropenia during their current antipsychotic treatment. Once leukopenia and neutropenia develops, drugs thought to be responsible for this side effect should be discontinued or dosages should be lowered. In some cases iniatition of lithium or G-CSF (granulocyte colony-stimulating factor therapy may be helpful in normalizing blood cell counts. Clinicans should avoid any combination of drugs known to cause hematological side effects. Besides during antipsychotic treatment, infection symptoms such as fever, cough, sore throat or

  20. Cernunnos deficiency: a case report.

    Turul, T; Tezcan, I; Sanal, O


    B cell-negative severe combined immunodeficiency (SCID) is caused by molecules involved in the variable (diversity) joining (V[D]J) recombination process. Four genes involved in the nonhomologous end joining pathway--Artemis, DNA-PKcs, DNA ligase 4, and Cernunnos--are involved in B cell-negative radiosensitive SCID. Deficiencies in DNA ligase 4 and the recently described Cernunnos gene result in microcephaly, growth retardation, and typical bird-like facies. Lymphopenia and hypogammaglobulinemia with normal or elevated immunoglobulin (Ig) M levels indicate a defect in V(D)J recombination. We present a case with recurrent postnatal pulmonary infections leading to chronic lung disease, disseminated molluscum contagiosum, lymphopenia, low IgG, IgA and normal IgM levels. Our patient had phenotypic features such as microcephaly and severe growth retardation. Clinical presentation in patients with the B cell-negative subtype ranges from SCID to atypical combined immunodeficiency, occasionally associated with autoimmune manifestations and cytomegalovirus infection. Our patient survived beyond infancy with combined immunodeficiency and no autoimmune manifestations. PMID:21721379

  1. Pontine Infarct Presenting with Atypical Dental Pain: A Case Report.

    Goel, Rajat; Kumar, Sanjeev; Panwar, Ajay; Singh, Abhishek B


    Orofacial pain' most commonly occurs due to dental causes like caries, gingivitis or periodontitis. Other common causes of 'orofacial pain' are sinusitis, temporomandibular joint(TMJ) dysfunction, otitis externa, tension headache and migraine. In some patients, the etiology of 'orofacial pain' remains undetected despite optimal evaluation. A few patients in the practice of clinical dentistry presents with dental pain without any identifiable dental etiology. Such patients are classified under the category of 'atypical odontalgia'. 'Atypical odontalgia' is reported to be prevalent in 2.1% of the individuals. 'Atypical orofacial pain' and 'atypical odontalgia' can result from the neurological diseases like multiple sclerosis, trigeminal neuralgia and herpes infection. Trigeminal neuralgia has been frequently documented as a cause of 'atypical orofacial pain' and 'atypical odontalgia'. There are a few isolated case reports of acute pontine stroke resulting in 'atypical orofacial pain' and 'atypical odontalgia'. However, pontine stroke as a cause of atypical odontalgia is limited to only a few cases, hence prevalence is not established. This case is one, where a patient presented with acute onset atypical dental pain with no identifiable dental etiology, further diagnosed as an acute pontine infarct on neuroimaging. A 40 years old male presented with acute onset, diffuse teeth pain on right side. Dental examination was normal. Magnetic resonance imaging(MRI) of the brain had an acute infarct in right pons near the trigeminal root entry zone(REZ). Pontine infarct presenting with dental pain as a manifestation of trigeminal neuropathy, has rarely been reported previously. This stresses on the importance of neuroradiology in evaluation of atypical cases of dental pain. PMID:26464604

  16. Keloidal Atypical Fibroxanthoma: Case and Review of the Literature

    Tongdee, Emily; Touloei, Khasha; Shitabata, Paul K.; Shareef, Shahjahan; Maranda, Eric L.


    Keloidal atypical fibroxanthoma (KAF) has recently been categorized as a variant of atypical fibroxanthoma. This paper will emphasize the importance of including KAF in both clinical and histological differential diagnosis of benign and malignant lesions which exhibit keloidal collagen and will also review the current literature on epidemiology, pathogenesis, histology, immunochemistry and treatments.

    Lista Martínez, Olalla; Rivas López, Luis Alfredo; Pombo Otero, Jorge Francisco; Amaro Cendón, Santiago; Bravo García, Christian; Villa Fernández, Juan Manuel


    Through August 2013, 105 cases of intracranial extraventricular neurocytoma (EVN) had been described; 6% were located in cerebellum and 22% were atypical EVN. A rare morphologic form of neurocytoma, atypical EVN has had only 24 cases reported to date. Its prognosis is poorer than the typical central neurocytoma. This case report describes an atypical cerebellar EVN, a form that has not been reported yet, hence the interest of this article. We emphasise its cystic nature and mural nodule, in an infrequent presentation. EVN are low-incidence tumours that we need to take into consideration when making the differential diagnosis of cystic cerebellar lesions with mural nodule. Given that the prognosis of atypical EVNs depends on the atypical nature and on the grade of resection, medical follow up has to be more constant, due to the greater degree of recurrence.

  18. Embryological and floral effects attributable to deficiencies following crosses with x-rayed pollen of lilium regale W

    Polyembryonic seeds of Lilium regale E. H. Wilson were induced by X irradiation of the pollen with 500 r. Mitotic analyses of 55 plants arising from the polyembryonic seeds disclosed that two sets of identical unattached twins were heterozygous for different gross deficiencies. Highly atypical flowers were produced by the deficient plants. Smaller deficiencies, beyond the limit of detection, undoubtedly were present in other sets of twins. Two sets of conjoined twins occurred. Increases or decreases in the number of floral parts were numerous; both members of a set of twins had similar flowers, indicating a common origin. It is concluded that X-ray induced deficiencies were responsible for cleavage during embryological development and the subsequent formation of atypical flowers. (author)

  19. Imaging the neurobiological substrate of atypical depression by SPECT

    Neurobiological abnormalities underlying atypical depression have previously been suggested. The purpose of this study was to explore differences at functional brain imaging between depressed patients with and without atypical features and healthy controls. Twenty-three out-patients with chronic depressive disorder recruited from a service for patients with audiological symptoms were investigated. Eleven fulfilled the DSM-IV criteria for atypical depression (mood reactivity and at least two of the following: weight gain, hypersomnia, leaden paralysis and interpersonal rejection sensitivity). Twenty-three healthy subjects served as controls. Voxel-based analysis was applied to explore differences in {sup 99m}Tc-HMPAO uptake between groups. Patients in the atypical group had a higher prevalence of bilateral hearing impairment and higher depression and somatic distress ratings at the time of SPECT. Significantly higher tracer uptake was found bilaterally in the atypical group as compared with the non-atypicals in the sensorimotor (Brodmann areas, BA1-3) and premotor cortex in the superior frontal gyri (BA6), in the middle frontal cortex (BA8), in the parietal associative cortex (BA5, BA7) and in the inferior parietal lobule (BA40). Significantly lower tracer distribution was found in the right hemisphere in the non-atypicals compared with the controls in BA6, BA8, BA44, BA45 and BA46 in the frontal cortex, in the orbito-frontal cortex (BA11, BA47), in the postcentral parietal cortex (BA2) and in the multimodal association parietal cortex (BA40). The differences found between atypical and non-atypical depressed patients suggest different neurobiological substrates in these patient groups. The putative links with the clinical features of atypical depression are discussed. These findings encourage the use of functional neuroimaging in psychiatric disorders. (orig.)

  1. Atypical Radiological Manifestation of Pulmonary Metastatic Calcification

    Kang, Eun Hae; Kim, Eun Sun; Kim, Chul Hwan; Ham, Soo Youn; Oh, Yu Whan [Korea University College of Medicine, Seoul (Korea, Republic of)


    Metastatic pulmonary calcification is a condition of calcium deposition in the normal pulmonary parenchyma, and this is secondary to abnormal calcium metabolism without any prior soft tissue damage. The predisposing factors for this condition include chronic renal failure, hypercalcemia and increased tissue alkalinity. The most common radiologic manifestation consists of poorly defined nodular opacities in the upper lung zone. These opacities reflect the deposition of calcium salts in the pulmonary interstitium. We present here a case of metastatic pulmonary calcification in a patient who recovered from pneumonia with sepsis and whose high-resolution CT (HRCT) images demonstrated localized parenchymal airspace calcification that was limited to the bilateral lower lobes. These lower lobes had been involved with pneumonic consolidation without calcification, as seen on the previous CT scan. In summary, we report here on an atypical presentation of metastatic pulmonary calcification that showed dense airspace consolidation localized to the bilateral lower lobes in a patient with primary hyperparathyroidism and pneumonia.

  2. [Atypical early posttraumatic syndromes (author's transl)].

    Muller, G E


    In a consecutive series of 1,925 head injuries, 283 patients (14.7%), could not be classified, neither in the group of simple head injuries without cerebral symptoms, nor in the group of typical concussions characterized by immediate amnesia or observed coma. We have prefered the rather neutral term of atypical early posttraumatic syndromes. In this group, apart from neurovegetative manifestations, partial disturbances of consciousness and perception, we have also classified delayed disturbances of consciousness. Special attention has been given to migraineous phenomena and to a syndrome, characteristic for children, described by Mealey. This is an intermediate group important from a medico-legal point of view because certain transient cerebral manifestations risk to be mistaken for psychological reactions. On the other hand symptoms probably of psychic origin were discussed. PMID:4469864

  3. Pedal edema associated with atypical antipsychotics

    Santanu Munshi


    Full Text Available This study describes a patient diagnosed as a case of bipolar affective disorder complaining of bothersome incidence of pedal edema 1 month after the initiation of atypical antipsychotic regimen with risperidone and quetiapine. All hematological and biochemical profiles were found to be normal. On discontinuation of risperidone, the condition remained unresolved even after 2 weeks, and the edema progressed reaching her calves. On tapering the dose of quetiapine, she started showing gradual improvement in edematous condition. Quetiapine was slowly discontinued. No further recurrence of edema occurred, and hence, no further medication changes were implemented. Pedal edema was found to be resolved within weeks of dechallenge of the regimen. Naranjo adverse drug reaction probability scale gave a score of 7 which denotes "probable" adverse drug reaction with quetiapine.

  4. [Treatment of atypical and neurotic depression].

    Leitner, P; Umann, E; Kulawik, H


    Hitherto it has not been usual to talk in the German language about the therapy-oriented concept of two forms of the progress of atypical depression (Type A and Type V). The characteristic symptom of Type A is angst, together with phobias, physical complaints, etc. In Type V there are vegetative symptoms, often towards evening (Hypersomnia, difficulty in getting to sleep, increased appetite, increased weight, increased libido), accompanied by hysterical extrovert personality traits, and of intermittent occurrence. These clinical pictures are amenable to psychopharmalogical therapy. In conformity with the assumption of "somatic accommodation" treatment with antidepressives is recommended in the case neurotic depression, too, at least in the initial stages of treatment.

  5. Atypical subtrochanteric and diaphyseal femoral fractures

    Shane, Elizabeth; Burr, David; Abrahamsen, Bo;


    Bisphosphonates (BPs) and denosumab reduce the risk of spine and nonspine fractures. Atypical femur fractures (AFFs) located in the subtrochanteric region and diaphysis of the femur have been reported in patients taking BPs and in patients on denosumab, but they also occur in patients with no...... exposure to these drugs. In this report, we review studies on the epidemiology, pathogenesis, and medical management of AFFs, published since 2010. This newer evidence suggests that AFFs are stress or insufficiency fractures. The original case definition was revised to highlight radiographic features that...... distinguish AFFs from ordinary osteoporotic femoral diaphyseal fractures and to provide guidance on the importance of their transverse orientation. The requirement that fractures be noncomminuted was relaxed to include minimal comminution. The periosteal stress reaction at the fracture site was changed from a...

  6. Case Report: Atypical Cornelia de Lange Syndrome.

    Leanza, Vito; Rubbino, Gabriella; Leanza, Gianluca


    Cornelia de Lange Syndrome (CdLS) (also called Bushy Syndrome or Amsterdam dwarfism), is a genetic disorder that can lead to several alterations. This disease affects both physical and neuropsychiatric development. The various abnormalities include facial dysmorphia (arched eyebrows, synophrys, depressed nasal bridge, long philtrum, down-turned angles of the mouth), upper-extremity malformations, hirsutism, cardiac defects, and gastrointestinal alterations. The prevalence of this syndrome is approximately one per 15,000. Ultrasound is not the perfect means to diagnose CdLS, however, many abnormalities can be detected prenatally by scrupulous image observation. We report an atypical CdLS case characterized by increased nuchal translucency in the first trimester, normal karyotype, saddle nose, micrognathia with receding jaw, low set ears, facies senilis, arthrogryposis of the hands, absence of the Aranzio ductus venous, dilatation of gallbladder and bowel, a unique umbilical artery, increased volume of amniotic fluid, and intrauterine growth retardation ending with the interruption of pregnancy.

  7. Thymic carcinoma presenting as atypical chest pain.

    Siddiqui, Sadiq; Connelly, Tara; Keita, Luther; Blazkova, Sylvie; Veerasingam, Dave


    A 58-year-old woman with a 2-month history of atypical chest pain was referred to the chest pain clinic by the general practitioner. Exercise stress test was positive and subsequent coronary angiogram revealed significant triple vessel disease with left ventricular impairment requiring a coronary artery bypass graft (CABG). The patient had a chest X-ray as part of the preoperative work up. Chest X-ray revealed a large anterior mediastinal mass. Subsequent thorax CT revealed a 7.2 cm anterior mediastinal mass. CT-guided biopsy of the mass revealed the diagnosis of a poorly differentiated thymic basaloid carcinoma. The patient was successfully treated with concomitant surgery involving complete resection of the mass and a CABG procedure. PMID:26607199

  8. A case of atypical progressive supranuclear palsy

    Spaccavento S


    Full Text Available Simona Spaccavento, Marina Del Prete, Angela Craca, Anna Loverre IRCCS Salvatore Maugeri Foundation, Cassano Murge, Bari, Italy Background: Progressive supranuclear palsy (PSP is a neurodegenerative extrapyramidal syndrome. Studies have demonstrated that PSP can present clinically as an atypical dementing syndrome dominated by a progressive apraxia of speech (AOS and aphasia. Aim: We aimed to investigate the clinical presentation of PSP, using a comprehensive multidimensional evaluation, and the disease response to various pharmacological treatments. Methods: A 72-year-old right-handed male, with 17 years education, who first presented with aphasia, AOS, depression, apathy, and postural instability at 69 years; a complete neuropsychological evaluation, tapping the different cognitive domains, was performed. Results: Testing revealed a moderate global cognitive deficit (Mini-Mental State Examination test score =20, low memory test scores (story recall, Rey’s 15-word Immediate and Delayed Recall, and poor phonemic and semantic fluency. The patient’s language was characterized by AOS, with slow speech rate, prolonged intervals between syllables and words, decreased articulatory accuracy, sound distortions, and anomia. Behavioral changes, such as depression, anxiety, apathy, and irritability, were reported. The neurological examination revealed supranuclear vertical gaze palsy, poor face miming, and a mild balance deficit. Magnetic resonance imaging showed only widespread cortical atrophy. Single photon emission computed tomography demonstrated left > right frontotemporal cortical abnormalities. After 6 months, a further neuropsychological assessment showed a progression in cognitive deficits, with additional attention deficits. The patient reported frequent falls, but the neurological deficits remained unchanged. Neuroimaging tests showed the same brain involvement. Conclusion: Our case highlights the heterogeneity of the clinical features in

  9. Patterns and predictors of atypical language representation in epilepsy.

    Dijkstra, Krijn Kristian; Ferrier, Cyrille Henri


    In the majority of the normal population, the left hemisphere is dominant for language. In epilepsy, a higher proportion of 'atypical' language representation is encountered. This can follow one of three patterns: (1) altered interhemispheric representation, where the spectrum of lateralisation is shifted to the right; (2) interhemispheric dissociation of linguistic subfunctions; or (3) intrahemispheric changes in representation. Knowledge of these patterns is essential for avoiding postoperative language deficits in epilepsy patients undergoing surgery. Several predictors of atypical language representation exist. It is more prevalent in left-handed individuals. Lesions in rough proximity to classical language areas are more associated with atypical language, although in some cases, remote lesions, such as in the hippocampus, can also lead to altered language representation. The more disruptive the lesion, the more likely atypical language is to be found. Widespread and frequent interictal epileptiform discharges are also associated with atypical language. Atypical language representation is more likely to be present when injury or epilepsy onset occurred at a young age. Thus, a subgroup of patients can be defined in whom atypical language representation is more likely to be found. PMID:22942215

  10. Malignant atypical cell in urine cytology: a diagnostic dilemma

    Kakkar Nandita


    Full Text Available Abstract Aims The aim of this study was to find out the characteristic morphology of malignant atypical cells which were missed on routine cytology of urine. Materials and methods In this retrospective study, we examined detailed cytomorphology of 18 cases of atypical urinary cytology which were missed on routine examination and were further proved on histopathology as transitional cell carcinoma (TCC of bladder. The cytological features of these cases were compared with 10 cases of benign urine samples. Results There were 11 cases of high grade TCC and 7 cases of low grade TCC on histopathology of the atypical urine samples. Necrosis in the background and necrosed papillae were mostly seen in malignant atypical cells. The comet cells and cells with India ink nuclei (single cells with deep black structure-less nuclei were only observed in malignant atypical cells. The most consistent features in malignant atypical cells were: i high nuclear and cytoplasmic (N/C ratio ii nuclear pleomorphism iii nuclear margin irregularity iv hyperchromasia and v chromatin abnormalities Conclusion The present study emphasizes that nuclear features such as high N/C ratio, hyperchromasia and chromatin abnormalities are particularly useful for assessing the malignant atypical cells. Other cytological features such as comet cells and cells with India ink nuclei are also helpful for diagnosis but have limited value because they are less frequently seen.

  11. [The modern concept of atypical depression: four definitions].

    Ohmae, Susumu


    This report describes and compares four current concepts and definitions of atypical depression. Since its emergence, atypical depression has been considered a depressive state that can be relieved by MAO inhibitors. Davidson classified the symptomatic features of atypical depression into type A, which is predominated by anxiety symptoms, and type V, which is represented by atypical vegetative symptoms, such as hyperphagia, weight gain, oversleeping, and increased sexual drive. Features that are shared by both subtypes include: early onset, female predominance, outpatient predominance, mildness, few suicide attempts, nonbipolarity, nonendogeneity, and few psychomotor changes. Based on these features, bipolar depression can also be defined as atypical depression type V. Herein, we examine and classify four concepts of atypical depression according to the endogenous-nonendogenous (melancholic-nonmelancholic) and unipolar-bipolar dichotomies. The Columbia University group (see Quitkin, Stewart, McGrath, Klein et al.) and the New South Wales University group (see Parker) consider atypical depression to be chronic, mild, nonendogenous (nonmelancholic), unipolar depression. The former group postulates that mood reactivity is necessary, while the latter asserts the structural priority of anxiety symptoms over mood symptoms and the significance of interpersonal rejection sensitivity. For the Columbia group, the significance of mood reactivity reflects the theory that mood nonreactivity is the essential symptom of "endogenomorphic depression", which was proposed by Klein as typical depression. Thus, mood reactivity is not related to overreactivity or hyperactivity, which are often observed in atypical depressives. However, Parker postulates that psychomotor symptoms are the essential features of melancholia, which he recognizes as typical depression; therefore, the New South Wales group does not recognize the significance of mood reactivity. The New South Wales group

    Paroxysmal exercise-induced dystonia (PED) is one of the rarer forms of paroxysmal dyskinesia, and can occur in sporadic or familial forms. We report a family (male index case, mother and maternal grandfather) with autosomal dominant inheritance of paroxysmal exercise-induced dystonia. The dystonia began in childhood and was only ever induced…

  13. [Apropos of atypical melancholia with Sustiva (efavirenz)].

    Lang, J P; Halleguen, O; Picard, A; Lang, J M; Danion, J M


    The treatment of HIV infection has changed dramatically in recent years as a result of the development of new drugs which allows a variety of multitherapy combinations more adapted to patients' needs and thereby improving compliance. Efavirenz is a non-nucleoside reverse transcriptase inhibitor. In addition to a potent antiretroviral activity, efavirenz is an easy-to-take drug with once-daily dosing and is usually well tolerated. Efavirenz, however, may induce psychic alterations which are variable and atypical in both their clinical presentation and severity. As early as the first days of treatment, efavirenz may provoke surprising phenomena such as nightmares, vivid dreams, hallucinations or illusions, and twilight states. Depersonalization and derealization episodes, personality alterations, stream of thought troubles and unusual thought contents, atypical depression and cognitive disorders have also been observed. These phenomena may occur either early or later on treatment. The prevalence of severe psychic disorders is less than 5%, but they are often responsible for harmful treatment discontinuations. Psychiatric side effects are heterogeneous and probably not related to pre-existing psychologic weakness. We do not have enough data to evaluate these side effects and their etiopathogeny. The drug could act directly on the central nervous system since it crosses the blood-brain barrier, on the serotoninergic and dopaminergic systems. Some authors have compared efavirenz-induced psychic effects to those associated with LSD and found structural similarities between the two molecules. However, the heterogeneity and low prevalence of the psychiatric side effects of efavirenz suggest and individual sensitivity. In order to improve patient care, a better clinical approach, neuropsychological evaluation, and functional brain imagery should be used to progress in the analysis and comprehension of these disorders. We discuss in this paper the case of Mister H. This HIV

  16. Teaching strategies for atypical presentation of illness in older adults.

    Gray-Miceli, Deanna; Aselage, Melissa; Mezey, Mathy


    Atypical presentation of illness is a phenomenon where "seeing is believing." Expert geriatric nurses and clinicians know all too well the early signs and symptoms of this phenomenon, which frequently masquerades bacterial infections, pain, acute myocardial infarction, heart failure, or other serious medical ailments in older adults. Students, however, as novices to clinical practice, require interactive learning approaches to reflect on the patient's illness presentations, help with developing the necessary skills to analyze and synthesize clinically relevant data, and witness resolution of an atypical presentation when found and treated. Use of a case study as an educational tool can facilitate critical thinking about a clinical problem, such as atypical presentation of illness, for students within a problem-based learning format.

  19. Atypical presentation of macrophagic myofasciitis 10 years post vaccination.

    Ryan, Aisling M


    Macrophagic myofasciitis (MMF) is an uncommon inflammatory disorder of muscle believed to be due to persistence of vaccine-derived aluminium hydroxide at the site of injection. The condition is characterised by diffuse myalgias, arthralgia and fatigue. We describe a patient with histologically confirmed MMF whose presentation was atypical with left chest and upper limb pain beginning more than 10 years post vaccination. Treatment with steroids led to symptomatic improvement. Although rare, clinicians should consider MMF in cases of atypical myalgia.

  2. Persistent consequences of atypical early number concepts

    MichèleM. M.Mazzocco


    Full Text Available How does symbolic number knowledge performance help identify young children at risk for poor mathematics achievement outcomes? In research and practice, classification of mathematics learning disability (MLD, or dyscalculia is typically based on composite scores from broad measures of mathematics achievement. These scores do predict later math achievement levels, but do not specify the nature of math difficulties likely to emerge among students at greatest risk for long-term mathematics failure. Here we report that gaps in 2nd and 3rd graders’ number knowledge predict specific types of errors made on math assessments at Grade 8. Specifically, we show that early whole number misconceptions predict slower and less accurate performance, and atypical computational errors, on Grade 8 arithmetic tests. We demonstrate that basic number misconceptions can be detected by idiosyncratic responses to number knowledge items, and that when such misconceptions are evident during primary school they persist throughout the school age years, with variable manifestation throughout development. We conclude that including specific qualitative assessments of symbolic number knowledge in primary school may provide greater specificity of the types of difficulties likely to emerge among students at risk for poor mathematics outcomes.

    Full Text Available Dengue fever and dengue haemorrhagic fever are important arboviral diseases. Dengue virus belongs to family Flaviviridae , has four serotypes that spread by the bite of infected Aedes mosquitoes . Dengue epidemics can have a significant economic and health t oll. Worldwide, an estimated 3.6 billion people are at risk of infection with about 50 - 100 million new cases each year Illness produced by any of the four dengue virus serotypes varies from mild asymptomatic illness to severe fatal dengue haemorrhagic fe ver/dengue shock syndrome (DHF/DSS. During the early febrile stage clinicians cannot predict which patients will progress to severe disease. Atypical manifestations were reported are associated with high risk of mortality. The existing WHO dengue classific ation scheme and case definitions have some drawbacks. A global strategy to reduce the disease burden using integrated vector management in conjunction with early and accurate diagnosis has been advocated. Antiviral drugs and vaccines that are currently un der development could also make an important contribution to dengue control in the future

  4. Atypical proliferating mucinous tumors of gigantic dimensions

    Likić-Lađević Ivana


    Full Text Available Background. Ovarian tumors of low malignant potential (LMP are also known as atypically proliferating tumors. Ovarian tumors of LPM account for approximately 15% of all epithelial ovarian cancers. Mean age of occurrence is 40 years and they are 15-20 cm in diameter. Case report. A 32-year-old female patient was hospitalized as an urgent case with a large tumor mass that filled the entire abdomen. Cyst was 100 × 70 cm dimensions belonging to the right ovary and filled with 18 liters of content. Right adnexectomy, resection of the second ovary, as well as biopsy of the omentum were performed. Lymphadenectomy of the right iliac and obturator area was also performed. After receiving definitive histopathological results it was decided to perform a radical reoperation. On the 10th postoperative day relaparotomy, total hysterectomy and left adnexectomy were performed. The patient was released on the 6th postoperative day. She used to come to regular examinations up to date. Conclusion. This case is a proof that LMP tumors have low malignant potential, they grow slowly and can reach great proportions.

  5. Atypical focal nodular hyperplasia of the liver

    Muhammad Rizwan Khan; Taimur Saleem; Tanveer Ul Haq; Kanwal Aftab


    BACKGROUND: Focal nodular hyperplasia, a benign hepatic tumor, is usually asymptomatic. However, rarely the entity can cause symptoms, mandating intervention. METHOD: We present a case of focal nodular hyperplasia of the liver, which caused a considerable diagnostic dilemma due to its atypical presentation. RESULTS: A 29-year-old woman presented with a 15-year history of a progressively increasing mass in the right upper quadrant which was associated with pain and emesis. Examination showed a firm, mobile mass palpable below the right subcostal margin. A computed tomography scan of the abdomen showed an exophytic mass arising from hepatic segments III and IVb. Trucut biopsy of the hepatic mass was equivocal. Angiography showed a vascular tumor that was supplied by a tortuous branch of the proper hepatic artery. Surgical intervention for removal of the mass was undertaken. Intra-operatively, two large discrete tumors were found and completely resected. Histopathological examination showed features consistent with focal nodular hyperplasia. CONCLUSION: This description of an unusual case of focal nodular hyperplasia of the liver highlights the point that the diagnosis of otherwise benign hepatic tumors may be difficult despite extensive work-up in some cases.

  6. Atypical mitochondrial inheritance patterns in eukaryotes.

    Breton, Sophie; Stewart, Donald T


    Mitochondrial DNA (mtDNA) is predominantly maternally inherited in eukaryotes. Diverse molecular mechanisms underlying the phenomenon of strict maternal inheritance (SMI) of mtDNA have been described, but the evolutionary forces responsible for its predominance in eukaryotes remain to be elucidated. Exceptions to SMI have been reported in diverse eukaryotic taxa, leading to the prediction that several distinct molecular mechanisms controlling mtDNA transmission are present among the eukaryotes. We propose that these mechanisms will be better understood by studying the deviations from the predominating pattern of SMI. This minireview summarizes studies on eukaryote species with unusual or rare mitochondrial inheritance patterns, i.e., other than the predominant SMI pattern, such as maternal inheritance of stable heteroplasmy, paternal leakage of mtDNA, biparental and strictly paternal inheritance, and doubly uniparental inheritance of mtDNA. The potential genes and mechanisms involved in controlling mitochondrial inheritance in these organisms are discussed. The linkage between mitochondrial inheritance and sex determination is also discussed, given that the atypical systems of mtDNA inheritance examined in this minireview are frequently found in organisms with uncommon sexual systems such as gynodioecy, monoecy, or andromonoecy. The potential of deviations from SMI for facilitating a better understanding of a number of fundamental questions in biology, such as the evolution of mtDNA inheritance, the coevolution of nuclear and mitochondrial genomes, and, perhaps, the role of mitochondria in sex determination, is considerable.

  7. Atypical moral judgment following traumatic brain injury

    Angelica Muresan


    Full Text Available Previous research has shown an association between emotions, particularly social emotions, and moral judgments. Some studies suggested an association between blunted emotion and the utilitarian moral judgments observed in patients with prefrontal lesions. In order to investigate how prefrontal brain damage affects moral judgment, we asked a sample of 29 TBI patients (12 females and 17 males and 41 healthy participants (16 females and 25 males to judge 22 hypothetical dilemmas split into three different categories (non-moral, impersonal and personal moral. The TBI group presented a higher proportion of affirmative (utilitarian responses for personal moral dilemmas when compared to controls, suggesting an atypical pattern of utilitarian judgements. We also found a negative association between the performance on recognition of social emotions and the proportion of affirmative responses on personal moral dilemmas. These results suggested that the preference for utilitarian responses in this type of dilemmas is accompanied by difficulties in social emotion recognition. Overall, our findings suggest that deontological moral judgments are associated with normal social emotion processing and that frontal lobe plays an important role in both emotion and moral judgment.

  8. Atypical presentation of mucopolysaccharidosis type IVA.

    Rush, Eric T


    A 14 year old patient with short stature, type I diabetes, and cataracts was referred for evaluation of avascular necrosis of the femoral head. Radiography was suggestive of spondyloepiphyseal dysplasia with decreased bone mineral density for age. Targeted molecular and biochemical testing were normal in this patient. Whole exome sequencing was performed and showed compound heterozygosity for previously reported pathogenic GALNS variants which were diagnostic of mucopolysaccharidosis, type IVA (Morquio A). While this case describes neither a novel condition nor a new mutation, it does illustrate three important points in the diagnosis of patients with atypical forms of MPS IVA. First, that in many instances urine glycosaminoglycan analysis is not sufficient to rule out MPS IVA as a potential diagnosis. Patients in whom biochemical screening is advised should have measurement of leukocyte enzymatic activity. Second, that in patients with radiographic evidence of spondyloepiphyseal dysplasia with additional features or with normal targeted testing, MPS IVA should remain in the differential diagnosis. Third, that whole exome sequencing represents a viable diagnostic platform for evaluation of patients with unknown skeletal or metabolic disease. PMID:27331011

  17. Atypical sonographic patterns of fibroadenoma of the breast : pathologic correlation

    To correlate the atypical sonographic patterns of fibroadenoma of the breast with the pathologic findings. Among 203 surgically proven 43 which were sonographically atypical fibroadenomas, were retrospectively reviewed. The diagnostic criteria for atypical variety, as seen on sonography, were an ill-defined margin, microlobulated or irregular shape, heterogeneous internal echo-pattern, posterior shadowing, microcalcification, and clefts. The atypical sonographic patterns of these 43 fibroadenomas were analysed and compared with the pathologic findings. Among 43 lesions, ill-defined margins or irregular shapes were seen in 15 cases, heterogeneous internal echo-patterns in 27, posterior attenuation in nine, and clefts in seven. Thirty-seven (86%) of the 43 were predominantly ductal or had a mixed ductal and stromal component. Eleven (73.3%) of fifteen ill-defined margin or irregular shaped lesions were caused by interdigitation of surrounding normal breast parenchyma and mass. Twenty two (81.5%) of 27 heterogeneous internal echo-pat-terns were related to dilated ducts, phyllodes features, collagen bundles, adenosis, microcalcification, or fat vacuoles. Eight (88.9%) of nine posterior attenuations were caused by collagen bundles, microcalcification, ductal proliferation or dilatation. All seven cases showing clefts revealed phyllodes features and dilated ducts. Most atypical fibroadenomas had a predominantly ductal or mixed component. Ill-defined margin or irregular shape was mainly due to interdigitation of normal surrounding parenchyma. Variable histologic features were related to the heterogeneous internal echo-pattern, posterior shadowing, and the clefts revealed by atypical sonographic findings

  18. Exploring atypical verb+noun combinations in learner technical writing

    María José Luzón Marco


    Full Text Available Professional and academic discourse is characterised by a specific phraseology, which usually poses problems for students. This paper investigates atypical verb+noun collocations in a corpus of English technical writing of Spanish students. I focus on the type of verbs that most frequently occurred in these awkward or questionable combinations and attempt to explore the reasons why the learners deviate from NS's norms. The analysis indicates that these learners tend to have problems with a set of sub-technical and high-frequency verbs. Deviant combinations involving these verbs are frequently the result of a deficient knowledge of the phraseology of academic and technical discourse. The unawareness of collocations that are typical of this discourse often leads students to create V+N combinations by relying on the “Open Choice Principle” (Sinclair, 1991 or by using patterns from their mother tongue.El discurso profesional y académico se caracteriza por una fraseología específica, que suele plantear problemas a los estudiantes.

El análisis indica que estos estudiantes suelen tener problemas con un grupo de verbos sub-técnicos y verbos de alta frecuencia. Las combinaciones atípicas en las que estos verbos aparecen son frecuentemente el resultado de un conocimiento deficiente de la fraseología del discurso académico y técnico.

  19. Atypical antipsychotics in bipolar disorder: systematic review of randomised trials

    Moore R Andrew


    Full Text Available Abstract Background Atypical antipsychotics are increasingly used for treatment of mental illnesses like schizophrenia and bipolar disorder, and considered to have fewer extrapyramidal effects than older antipsychotics. Methods We examined efficacy in randomised trials of bipolar disorder where the presenting episode was either depression, or manic/mixed, comparing atypical antipsychotic with placebo or active comparator, examined withdrawals for any cause, or due to lack of efficacy or adverse events, and combined all phases for adverse event analysis. Studies were found through systematic search (PubMed, EMBASE, Cochrane Library, and data combined for analysis where there was clinical homogeneity, with especial reference to trial duration. Results In five trials (2,206 patients participants presented with a depressive episode, and in 25 trials (6,174 patients the presenting episode was manic or mixed. In 8-week studies presenting with depression, quetiapine and olanzapine produced significantly better rates of response and symptomatic remission than placebo, with NNTs of 5–6, but more adverse event withdrawals (NNH 12. With mania or mixed presentation atypical antipsychotics produced significantly better rates of response and symptomatic remission than placebo, with NNTs of about 5 up to six weeks, and 4 at 6–12 weeks, but more adverse event withdrawals (NNH of about 22 in studies of 6–12 weeks. In comparisons with established treatments, atypical antipsychotics had similar efficacy, but significantly fewer adverse event withdrawals (NNT to prevent one withdrawal about 10. In maintenance trials atypical antipsychotics had significantly fewer relapses to depression or mania than placebo or active comparator. In placebo-controlled trials, atypical antipsychotics were associated with higher rates of weight gain of ≥7% (mainly olanzapine trials, somnolence, and extrapyramidal symptoms. In active controlled trials, atypical antipsychotics

  20. Glucose-6 phosphate dehydrogenase deficiency and psychotic illness

    Vijender Singh


    Full Text Available Mr. T, a 28-year-old unmarried male, a diagnosed case of Glucose-6 Phosphate Dehydrogenase (G6PD deficiency since childhood, presented with 13 years of psychotic illness and disturbed biological functions. He showed poor response to antipsychotics and mood stabilizers and had three prior admissions to Psychiatry. There was a family history of psychotic illness. The General Physical Examination and Systemic Examination were unremarkable. Mental Status Examination revealed increased psychomotor activity, pressure of speech, euphoric affect, prolixity, delusion of persecution, delusion of grandiosity, delusion of control, thought withdrawal and thought insertion, and second and third person auditory hallucinations, with impaired judgment and insight. A diagnosis of schizophrenia paranoid type, with a differential diagnosis of schizoaffective disorder manic subtype, was made. This case is being reported for its rarity and atypicality of clinical presentation, as well as a course of psychotic illness in the G6PD Deficiency state,with its implications on management.

  1. Thiamine deficiency and delirium.

    Osiezagha, Kenneth; Ali, Shahid; Freeman, C; Barker, Narviar C; Jabeen, Shagufta; Maitra, Sarbani; Olagbemiro, Yetunde; Richie, William; Bailey, Rahn K


    Thiamine is an essential vitamin that plays an important role in cellular production of energy from ingested food and enhances normal neuronal actives. Deficiency of this vitamin leads to a very serious clinical condition known as delirium. Studies performed in the United States and other parts of the world have established the link between thiamine deficiency and delirium. This literature review examines the physiology, pathophysiology, predisposing factors, clinical manifestations (e.g., Wernicke's encephalopathy, Wernicke-Korsakoff syndrome, structural and functional brain injuries) and diagnosis of thiamine deficiency and delirium. Current treatment practices are also discussed that may improve patient outcome, which ultimately may result in a reduction in healthcare costs. PMID:23696956

  2. Atypical Hemolytic-Uremic Syndrome: A Clinical Review.

    Nayer, Ali; Asif, Arif


    Atypical hemolytic-uremic syndrome (HUS) is a rare life-threatening disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia, and ischemic injury to organs, especially the kidneys. Microvascular injury and thrombosis are the dominant histologic findings. Complement activation through the alternative pathway plays a critical role in the pathogenesis of atypical HUS. Genetic abnormalities involving complement regulatory proteins and complement components form the molecular basis for complement activation. Endothelial cell dysfunction, probably because of the effects of complement activation, is an intermediate stage in the pathophysiologic cascade. Atypical HUS has a grave prognosis. Although mortality approaches 25% during the acute phase, end-stage renal disease develops in nearly half of patients within a year. Atypical HUS has a high recurrence rate after renal transplantation, and recurrent disease often leads to graft loss. Plasma therapy in the form of plasma exchange or infusion has remained the standard treatment for atypical HUS. However, many patients do not respond to plasma therapy and some require prolonged treatment. Approved by the Food and Drug Administration in the treatment of atypical HUS, eculizumab is a humanized monoclonal antibody that blocks cleavage of complement C5 into biologically active mediators of inflammation and cytolysis. Although case reports have shown the efficacy of eculizumab, randomized clinical trials are lacking. Therapeutic strategies targeting endothelial cells have demonstrated promising results in experimental settings. Therefore, inhibitors of angiotensin-converting enzyme, HMG-CoA reductase, and xanthine oxidase as well as antioxidants, such as ascorbic acid, may have salutary effects in patients with atypical HUS.

  3. Lessons learned from Toulouse and Buncefield disasters: from risk analysis failures to the identification of atypical scenarios through a better knowledge management.

    Paltrinieri, Nicola; Dechy, Nicolas; Salzano, Ernesto; Wardman, Mike; Cozzani, Valerio


    The recent occurrence of severe major accidents has brought to light flaws and limitations of hazard identification (HAZID) processes performed for safety reports, as in the accidents at Toulouse (France) and Buncefield (UK), where the accident scenarios that occurred were not captured by HAZID techniques. This study focuses on this type of atypical accident scenario deviating from normal expectations. The main purpose is to analyze the examples of atypical accidents mentioned and to attempt to identify them through the application of a well-known methodology such as the bow-tie analysis. To these aims, the concept of atypical event is accurately defined. Early warnings, causes, consequences, and occurrence mechanisms of the specific events are widely studied and general failures of risk assessment, management, and governance isolated. These activities contribute to outline a set of targeted recommendations, addressing transversal common deficiencies and also demonstrating how a better management of knowledge from the study of past events can support future risk assessment processes in the identification of atypical accident scenarios. Thus, a new methodology is not suggested; rather, a specific approach coordinating a more effective use of experience and available information is described, to suggest that lessons to be learned from past accidents can be effectively translated into actions of prevention.

  15. Symptomatic atypical femoral fractures are related to underlying hip geometry.

    Taormina, David P; Marcano, Alejandro I; Karia, Raj; Egol, Kenneth A; Tejwani, Nirmal C


    The benefits of bisphosphonates are well documented, but prolonged use has been associated with atypical femur fractures. Radiographic markers for fracture predisposition could potentially aid in safer medication use. In this case-control designed study, we compared hip radiographic parameters and the demographic characteristics of chronic bisphosphonate users who sustained an atypical femoral fracture with a group of chronic bisphosphonate users who did not sustain an atypical femur fracture and also a group who sustained an intertrochanteric hip fracture. Radiographic parameters included were neck-shaft angle (NSA), hip-axis length (HAL) and center-edge angle (CE). Multivariate regression was used to evaluate the relationship between radiographic measures and femur fracture. Receiver-operating characteristic analysis determined cut-off points for neck-shaft angle and risk of atypical femur fracture. Ultimately, pre-fracture radiographs of 53 bisphosphonate users who developed atypical fracture were compared with 43 asymptomatic chronic bisphosphonate users and 64 intertrochanteric fracture patients. Duration of bisphosphonate use did not statistically differ between users sustaining atypical fracture and those without fracture (7.9 [±3.5] vs. 7.7 [±3.3] years, p=0.7). Bisphosphonate users who fractured had acute/varus pre-fracture neck-shaft angles (p<0.001), shorter hip-axis length (p<0.01), and narrower center-edge angles (p<0.01). Regression analysis revealed associations between neck-shaft angle (OR=0.89 [95% CI=0.81-0.97; p=0.01), center edge angle (OR=0.89 [95% CI=0.80-0.99]; p=0.03), and BMI (OR=1.15 [95% CI=1.02-1.31; p=0.03) with fracture development. ROC curve analysis (AUC=0.67 [95% CI=0.56-0.79]) determined that a cut-off point for neck-shaft angle <128.3° yielded 69% sensitivity and 63% specificity for development of atypical femoral fracture. Ultimately, an acute/varus angle of the femoral neck, high BMI, and narrow center-edge angle were

  16. Clinical significance of complement deficiencies.

    Pettigrew, H David; Teuber, Suzanne S; Gershwin, M Eric


    The complement system is composed of more than 30 serum and membrane-bound proteins, all of which are needed for normal function of complement in innate and adaptive immunity. Historically, deficiencies within the complement system have been suspected when young children have had recurrent and difficult-to-control infections. As our understanding of the complement system has increased, many other diseases have been attributed to deficiencies within the complement system. Generally, complement deficiencies within the classical pathway lead to increased susceptibility to encapsulated bacterial infections as well as a syndrome resembling systemic lupus erythematosus. Complement deficiencies within the mannose-binding lectin pathway generally lead to increased bacterial infections, and deficiencies within the alternative pathway usually lead to an increased frequency of Neisseria infections. However, factor H deficiency can lead to membranoproliferative glomerulonephritis and hemolytic uremic syndrome. Finally, deficiencies within the terminal complement pathway lead to an increased incidence of Neisseria infections. Two other notable complement-associated deficiencies are complement receptor 3 and 4 deficiency, which result from a deficiency of CD18, a disease known as leukocyte adhesion deficiency type 1, and CD59 deficiency, which causes paroxysmal nocturnal hemoglobinuria. Most inherited deficiencies of the complement system are autosomal recessive, but properidin deficiency is X-linked recessive, deficiency of C1 inhibitor is autosomal dominant, and mannose-binding lectin and factor I deficiencies are autosomal co-dominant. The diversity of clinical manifestations of complement deficiencies reflects the complexity of the complement system. PMID:19758139

  19. Ichthyosiform mycosis fungoides with alopecia and atypical membranous nephropathy

    Qiang Zhou


    Full Text Available We describe here a rare case of variant of mycosis fungoides (MF: ichthyosiform MF with alopecia and atypical membranous nephropathy. The diagnosis was made based on the following findings: generalized ichthyosis-like eruption, alopecia, enlarged superficial lymph nodes, proteinuria, and hematuria, the histological features of the skin biopsy from both ichthyotic and alopecic lesions with immunohistochemical staining, and the renal biopsy examination with immunofluorescence. The histological examination of ichthyotic and alopecic lesions displayed a predominant infiltration of atypical lymphocytes in the upper dermis with the characteristics of epidermotropism and folliculotropism. Immunohistochemical studies demonstrated that most infiltrated atypical lymphocytes were CD3, CD4, and CD45RO positive, whereas negative for CD5, CD7, CD20, CD30, and CD56. A renal biopsy examination revealed atypical membranous nephropathy with deposition of immunoglobulin G (IgG, IgM, IgA, C1q, and C3. In this case atypical membranous nephropathy was involved, which is very uncommon and has never been presented in the literature to date. Although ichthyosiform MF usually features a relatively favorable course, diffuse alopecia and the renal involvement in this case might indicate aggressive disease and poor prognosis.

  20. Atypical growth of Renibacterium salmoninarum in subclinical infections.

    Hirvelä-Koski, V; Pohjanvirta, T; Koski, P; Sukura, A


    Two growth types of Renibacterium salmoninarum were isolated from subclinically infected rainbow trout, one producing the smooth colonies typical of R. salmoninarum and the other forming a thin film on the surface of the agar with no separate colonies. The atypical growth was present on kidney disease medium agar in primary cultures of the kidney but not on selective kidney disease medium (SKDM). Fluorescent antibody staining of the fresh isolate and polymerase chain reaction amplification were the most reliable techniques to identify the atypical growth of R. salmoninarum. The condition was reversible, with growth reverting from atypical to the smooth colony form in experimentally infected rainbow trout and under laboratory conditions. There was no mortality, or any clinical signs of bacterial kidney disease (BKD) in the fish challenged with the atypical growth, although small numbers of smooth colonies of R. salmoninarum were isolated from 8% of these fish. The atypical growth reported here may explain some of the failures of culture, when SKDM agar alone is used for the detection of BKD in subclinically infected fish. PMID:16351695

  1. Iron deficiency in Europe.

    Hercberg, S; Preziosi, P; Galan, P


    In Europe, iron deficiency is considered to be one of the main nutritional deficiency disorders affecting large fractions of the population, particularly such physiological groups as children, menstruating women and pregnant women. Some factors such as type of contraception in women, blood donation or minor pathological blood loss (haemorrhoids, gynaecological bleeding...) considerably increase the difficulty of covering iron needs. Moreover, women, especially adolescents consuming low-energy diets, vegetarians and vegans are at high risk of iron deficiency. Although there is no evidence that an absence of iron stores has any adverse consequences, it does indicate that iron nutrition is borderline, since any further reduction in body iron is associated with a decrease in the level of functional compounds such as haemoglobin. The prevalence of iron-deficient anaemia has slightly decreased in infants and menstruating women. Some positive factors may have contributed to reducing the prevalence of iron-deficiency anaemia in some groups of population: the use of iron-fortified formulas and iron-fortified cereals; the use of oral contraceptives and increased enrichment of iron in several countries; and the use of iron supplements during pregnancy in some European countries. It is possible to prevent and control iron deficiency by counseling individuals and families about sound iron nutrition during infancy and beyond, and about iron supplementation during pregnancy, by screening persons on the basis of their risk for iron deficiency, and by treating and following up persons with presumptive iron deficiency. This may help to reduce manifestations of iron deficiency and thus improve public health. Evidence linking iron status with risk of cardiovascular disease or cancer is unconvincing and does not justify changes in food fortification or medical practice, particularly because the benefits of assuring adequate iron intake during growth and development are well established

    Zahra Afravi


    Full Text Available Background/Objective: The incidence of primary CNS lymphomas (PCNSL is increasing. Timely diagnosis of PCNSL can lead to proper therapeutic management. There are some atypical imaging findings that may easily be misdiagnosed as other pathologic processes such as infectious and demyelinative diseases. As a result, histopathologic diagnosis is necessary for all suspected lesions."nPatients and Methods: In this research we studied 120 cases of PCNSL over the past 16 years. Some of them had atypical imaging findings, suggesting many differential diagnoses. Having said that, stereotactic biopsy was performed for all cases and the diagnosis was proved."nResults: We selected some interesting cases with atypical imaging findings of PCNSL, which were unlikely to be diagnosed without histopathologic evaluation. "nConclusion: PCNSL must be kept in mind as a differential diagnosis for other brain lesions. Histopathologic diagnosis is necessary for prompt management.

  4. Genetics Underlying Atypical Parkinsonism and Related Neurodegenerative Disorders.

    Scholz, Sonja W; Bras, Jose


    Atypical parkinsonism syndromes, such as dementia with Lewy bodies, multiple system atrophy, progressive supranuclear palsy and corticobasal degeneration, are neurodegenerative diseases with complex clinical and pathological features. Heterogeneity in clinical presentations, possible secondary determinants as well as mimic syndromes pose a major challenge to accurately diagnose patients suffering from these devastating conditions. Over the last two decades, significant advancements in genomic technologies have provided us with increasing insights into the molecular pathogenesis of atypical parkinsonism and their intriguing relationships to related neurodegenerative diseases, fueling new hopes to incorporate molecular knowledge into our diagnostic, prognostic and therapeutic approaches towards managing these conditions. In this review article, we summarize the current understanding of genetic mechanisms implicated in atypical parkinsonism syndromes. We further highlight mimic syndromes relevant to differential considerations and possible future directions. PMID:26501269

  6. Atypical femur fractures associated with bisphosphonates: from prodrome to resolution

    Braulio Sastre-Jala


    Full Text Available Atypical fractures related to the prolonged use of bisphosphonates are caused by low energy mechanisms and are characterized by oblique and transverse lines and frequent bilateralism. We present a clinical case of a patient who we believe illustrates, both in clinical and radiological aspects, the new definition of atypical femur fracture related to treatment using bisphosphonates treated conservatively and successfully with discharge and teriparatide 20 mcg/80 mcl s.c./24h. The appearance of painful symptoms in the upper thigh, especially if bilateral, in patients treated with bisphosphonates for long periods of time, makes it necessary to dismiss bone lesions that might otherwise suggest atypical fracture. In those cases where the fracture is incomplete, restoring bone metabolism through the administration of teriparatide 20 mcg/80 mcl s.c./24h could prevent displaced fractures.

  7. Atypical language representation in children with intractable temporal lobe epilepsy.

    Maulisova, Alice; Korman, Brandon; Rey, Gustavo; Bernal, Byron; Duchowny, Michael; Niederlova, Marketa; Krsek, Pavel; Novak, Vilem


    This study evaluated language organization in children with intractable epilepsy caused by temporal lobe focal cortical dysplasia (FCD) alone or dual pathology (temporal lobe FCD and hippocampal sclerosis, HS). We analyzed clinical, neurological, fMRI, neuropsychological, and histopathologic data in 46 pediatric patients with temporal lobe lesions who underwent excisional epilepsy surgery. The frequency of atypical language representation was similar in both groups, but children with dual pathology were more likely to be left-handed. Atypical receptive language cortex correlated with lower intellectual capacity, verbal abstract conceptualization, receptive language abilities, verbal working memory, and a history of status epilepticus but did not correlate with higher seizure frequency or early seizure onset. Histopathologic substrate had only a minor influence on neuropsychological status. Greater verbal comprehension deficits were noted in children with atypical receptive language representation, a risk factor for cognitive morbidity. PMID:27064828

  8. EPR dosimetry with synthetic A-type carbonated apatite

    Synthetic A-type carbonated apatite prepared in reproducible conditions were irradiated at room temperature with 60 Co γ rays. The EPR spectrum is associated to axial CO2- and orthorhombic CO3- species. Radicals used as dose marker in biological apatite are long live paramagnetic species. The stability of the post-irradiation signal of A-type apatite was investigated for more than one year. Measurements showed variations in the spectra attributed to unstable CO3- species, which can be eliminated by thermal treatments at 100 deg C for 24 hours. The CO2- spectrum can be identified in samples irradiated up to 0.2 Gy. All results indicate the A-type apatite as an appropriate material for radiotherapy dosimetry. (author)

  9. Atypical pyoderma gangrenosum in a patient with osteomyelofibrosis

    Živanović Dubravka


    Full Text Available Background. Atypical forms of pyoderma gangrenosum generally appear on the upper extremities; most frequently they are associated with myeloproliferative disorders, including osteomyelofibrosis. A response to systemic steroids is more pronounced than in classical form. Sometimes it may be the first sign of an underlying malignancy. Case report. We reported a patient with atypical pyoderma gangrenosum developed during the course of a myeloid malignancy - osteomyelofibrosis. The lesions occurred after a minor trauma. Painful blistering plaques, with an elevated, bluish-gray border were located on the dorsal aspect of hands. No skin malignancy was found. The lesions resolved rapidly to systemic steroids. Conclusion. Considering the unusual clinical presentation which makes the diagnosis difficult, as well as the fact that atypical forms of pyoderma gangrenosum can be the first sign of malignancies, especially myeloproliferative ones, recognizing this entity enables timely guiding future investigations toward their prompt detection.

  10. Gender-Atypical Mental Illness as Male Gender Threat.

    Michniewicz, Kenneth S; Bosson, Jennifer K; Lenes, Joshua G; Chen, Jason I


    The present study examined whether men view gender-atypical (i.e., feminine) psychological disorders as threats to their gender status. Men and women (N = 355) rated their expectations of gender status loss, feelings of distress, and help-seeking intentions in response to 10 different stereotypically masculine and feminine psychological disorders. Men as compared to women expected greater gender status loss for, and reported more distress to, gender-atypical versus gender-typical disorders. Expectations of gender status loss partially mediated the link between participant gender and distress at the thought of gender-atypical disorders. These findings suggest that feminine disorders pose more powerful gender status threats for men than masculine disorders do and that men's expectations of gender status loss for feminine disorders drive their negative reactions to these mental illnesses. The discussion emphasizes the importance of considering the gender-typicality of disorders, and the implications of these findings for clinical interventions. PMID:25595020

  11. Computerized tomography findings on schizophrenia and atypical psychosis

    The brain CTs of 54 endogenous psychotics (27 males, 27 females) who were less than 40 years of age and were first adimitted in Aichi Medical University from 1982 to 1986, and 20 controls (10 males, 10 females) were examined. Using Mitsuda's classification, we devided all the cases into 29 schizophrenics (18 males, 11 females) and 25 atypical psychotics (9 males, 16 females). In order to investigate the differences of CT findings between the two patient groups, the 3rd ventricle index (the ratio of 3rd ventricle width to the internal diameter of the skull), Evans'ratio, lateral ventricle brain ratio (VBR), Sylvian fissure to brain ratio, 4th ventricle to cerebellum ratio were determined. Schizophrenics had larger 3rd and lateral ventricles as well as Sylvian fissures when compared to controls, but atypical psychotics had not. Moreover, schizophrenics had larger 3rd and lateral ventricle than atypical psychotics. But in widths of Sylvian fissures there was no statistical significant difference between the two groups. Ventricle enlargements of schizophrenics did not correlate with duration of illness as well as age, and were not results of prior psychiatric treatment such as medication and EST. Therefore the following is suggested that, this abnormal CT findings predate the onset of schizophrenic psychoses. In atypical psychotics the changes of Sylvian fissures correlated with duration of illness, but not with age. Such observations may possibly suggest that recurrence of the illness might finally attain irreversible changes even in atypical psychotics. Finally, the heterogeneity of schizophrenia and the independence of atypical psychosis were also discussed. (author) 53 refs

  12. Uremic parkinsonism with atypical phenotypes and radiologic features.

    Yoon, Jee-Eun; Kim, Ji Sun; Park, Jeong-Ho; Lee, Kyung-Bok; Roh, Hakjae; Park, Sung Tae; Cho, Jin Whan; Ahn, Moo-Young


    Uremic encephalopathy with bilateral basal ganglia lesions has been reported as an acute neurometabolic disease which shows reversible clinical course and brain imaging features. The exact nature and pathophysiology have not been well established. We encountered two patients who showed a relapsing and aggravating course and an atypical phenotype including parkinsonism with paroxysmal dystonic head tremor and acute onset monoparesis of the lower extremity. They also showed unusual radiological findings which revealed combined lesions in the basal ganglia and cortex, persistent hemorrhagic transformation, and focal ischemic lesion in the internal capsule. Herein, we present the unusual phenomenology with atypical radiologic findings and suggest the possible multifactorial pathogenesis of uremic encephalopathy. PMID:26631408

  13. Atypical defects resulting in growth hormone insensitivity.

    Wit, Jan M; de Luca, Francesco


    Besides four well-documented genetic causes of GH insensitivity (GHI) (GHR, STAT5B, IGF1, IGFALS defects), several other congenital and acquired conditions are associated with GHI. With respect to its anabolic actions, GH induces transcription of IGF1, IGFBP3 and IGFALS through a complex regulatory cascade including GH binding to its receptor (GHR), activation of JAK2 and phosphorylation of STAT5b, which then trafficks to the nucleus. GH also activates the MAPK and PI3K pathways. The synthesis of GHR can be reduced by estrogen deficiency or corticosteroid excess, and is possibly decreased in African pygmies. An increased degradation of GHRs because of overexpression of cytokine-inducible SH2-containing protein (CIS) was suggested for some children with idiopathic short stature. Effects on several downstream components of GH signaling were observed for FGF21, cytokines, sepsis, fever and chronic renal failure. In Noonan syndrome and other "rasopathies" the activation of the RAS-RAF-MAPK-ERK pathway leads to inhibition of the JAK/STAT pathway. In contrast, fibroblasts from tall patients with Sotos syndrome showed a downregulation of this axis. Experimental and clinical evidence suggests that the NF-κB pathway plays a role in GH signaling. In a patient with an IκBα mutation presenting with short stature, GHI, severe immune deficiency and other features, NF-κB nuclear transportation and STAT5 and PI3K expression and activity were reduced. A patient with a mosaic de novo duplication of 17q21-25 presented with several congenital anomalies, GHI and mild immunodeficiency. Studies in blood lymphocytes showed disturbed signaling of the CD28 pathway, involving NF-κB and related proteins. Functional studies on skin fibroblasts revealed that NF-κB activation, PI3K activity and STAT5 phosphorylation in response to GH were suppressed, while the sensitivity to GH in terms of MAPK phosphorylation was increased. The expression of one of the duplicated genes, PRKCA, was

    Ornithine transcarbamylase deficiency (OTCD) is the most common type urea cycle enzyme deficiencies. This syndrome results from a deficiency of the mitochondrial enzyme ornithine transcarbamylase, which catalyzes the conversion of ornithine and carbamoyl phosphate to citrullin. Our case was a 28-year-old female diagnosed with OTCD following neurocognitive deficit during her first pregnancy. Although hyperammonemia was suspected as the cause of the patient's mental changes, there was no evidence of chronic liver disease. Plasma amino acid and urine organic acid analysis revealed OTCD. After combined modality treatment with arginine, sodium benzoate and hemodialysis, the patient's plasma ammonia level stabilized and her mental status returned to normal. At last she recovered without any damage left. PMID:25759629

    Full Text Available Pietro Gareri,1 Cristina Segura-García,2 Valeria Graziella Laura Manfredi,1 Antonella Bruni,2 Paola Ciambrone,2 Gregorio Cerminara,2 Giovambattista De Sarro,2 Pasquale De Fazio2 1Elderly Health Care, Azienda Sanitaria Provinciale Catanzaro, Catanzaro, Italy; 2Department of Health Sciences, University “Magna Græcia” of Catanzaro, Catanzaro, Italy Abstract: The use of atypical antipsychotic drugs in the elderly has become wider and wider in recent years; in fact, these agents have novel receptor binding profiles, good efficacy with regard to negative symptoms, and reduced extrapyramidal symptoms. However, in recent years, the use of both conventional and atypical antipsychotics has been widely debated for concerns about their safety in elderly patients affected with dementia and the possible risks for stroke and sudden death. A MEDLINE search was made using the words elderly, atypical antipsychotics, use, schizophrenia, psychosis, mood disorders, dementia, behavioral disorders, and adverse events. Some personal studies were also considered. This paper reports the receptor binding profiles and the main mechanism of action of these drugs, together with their main use in psychiatry and the possible adverse events in elderly people.

  20. Treatment of atypical trigeminal neuralgia with microvascular decompression

    Hai Jian


    Full Text Available Aim: To explore the methods for achieving pain relief in patients with atypical trigeminal neuralgia (TN using microvascular decompression (MVD. Study Design and Settings: Retrospective study of 26 patients treated during the years 2000 to 2004. Materials and Methods: Twenty-six patients in whom vascular compression of the trigeminal nerve was identified by high definition magnetic resonance tomographic angiography (MRTA were treated with MVD for atypical TN in our department. Clinical presentations, surgical findings and clinical outcomes were analyzed retrospectively. Results: In this study, single trigeminal division was involved in only 2 patients (8% and two or three divisions in the other 24 patients (92%. Of prime importance is the fact that in 46.2% of the patients, several conflicting vessels were found in association. Location of the conflicts around the circumference of the trigeminal root was supero-medial to the root in 53.5%, supero-lateral in 30.8% and inferior in 15.7%. MVD for atypical TN resulted in complete pain relief in 50% of the patients with complete decompression, partial pain relief in 30.8% and poor pain relief or pain recurrence in 19.2% of the patients without complete decompression postoperatively. Conclusions: Complete decompression of the entire trigeminal root plays an important role in achieving pain relief in patients with atypical TN with MVD.

  5. Early Freezing of Gait: Atypical versus Typical Parkinson Disorders.

    Lieberman, Abraham; Deep, Aman; Dhall, Rohit; Tran, An; Liu, Ming-Jai


    In 18 months, 850 patients were referred to Muhammad Ali Parkinson Center (MAPC). Among them, 810 patients had typical Parkinson disease (PD) and 212 had PD for ≤5 years. Among the 212 patients with early PD, 27 (12.7%) had freezing of gait (FOG). Forty of the 850 had atypical parkinsonism. Among these 40 patients, all of whom had symptoms for ≤5 years, 12 (30.0%) had FOG. FOG improved with levodopa in 21/27 patients with typical PD but did not improve in the 12 patients with atypical parkinsonism. FOG was associated with falls in both groups of patients. We believe that FOG unresponsive to levodopa in typical PD resembles FOG in atypical parkinsonism. We thus compared the 6 typical PD patients with FOG unresponsive to levodopa plus the 12 patients with atypical parkinsonism with the 21 patients with typical PD responsive to levodopa. We compared them by tests of locomotion and postural stability. Among the patients with FOG unresponsive to levodopa, postural stability was more impaired than locomotion. This finding leads us to believe that, in these patients, postural stability, not locomotion, is the principal problem underlying FOG. PMID:25785228

  7. Large saphenous venous graft aneurysm mimicking atypical mediastinal mass

    Krotin Mirjana


    Full Text Available Background. Saphenous venous graft (SVG aneurysm is a very rare but potentially fatal complication of the coronary artery bypass surgery. Case report. We reported a case of 72-year-old man admitted to hospital because of atypical chest pain related to body motions in horizontal position, especially to the left side. Pain was followed by dispnea, palpitations, fatigue, cough, yellow sputum expectorations, as well as elevated temperature. He had had coronary artery bypass grafting (CABG surgery with saphenous vein grafts (SVGs to the left anterior descending artery (LAD and right coronary artery (RCA 27 years earlier. Chest X-ray revealed a poor-defined shadow in the region of the right atrium. A transthoracic echocardiogram revealed an atypical tumorous mediastinal mass near the right atrium and right ventricle that seemed partially calcified on transesophaeal echocardiography (TEE. CT scan confirmed an atypical mediastinal mass in contact with the right ventricle that might be a right ventricle aneurysm, pericardial cyst or SVG aneurysm. Coronary angiography was performed subsequently and it revealed a big saphenous venous graft aneurysm originating from the previous venous graft to the RCA. The aneurysm was resected and a new bypass graft was placed. Histopathology confirmed a true aneurysm of the venous graft. Conclusion. Although SVG aneurysm is a very rare complication of CABG surgery, patients presenting with atypical hilar or mediastinal mass following CABG should always be evaluated firstly for existence of this cardiosurgical complication.

  9. Use of Atypical Antipsychotics in Nursing Homes and Pharmaceutical Marketing

    Pimentel, Camilla B.; Donovan, Jennifer L.; Field, Terry S.; Gurwitz, Jerry H.; Harrold, Leslie R.; Kanaan, Abir O.; Lemay, Celeste A.; Mazor, Kathleen M.; Tjia, Jennifer; Briesacher, Becky A.


    BACKGROUND Many nursing home (NH) residents are prescribed atypical antipsychotics despite US Food and Drug Administration warnings of increased risk of death in older adults with dementia. Aggressive pharmaceutical marketing has been cited as a potential cause, although data are scarce. The objectives of this study were to describe the current extent and type of pharmaceutical marketing in NHs in one state, and to provide preliminary evidence for the potential influence of pharmaceutical marketing on the use of atypical antipsychotics in NHs. DESIGN Nested mixed-methods, cross-sectional study of NHs in a cluster randomized trial. SETTING 41 NHs in Connecticut. PARTICIPANTS NH administrators, directors of nursing and medical directors (n = 93, response rate 75.6%). MEASUREMENTS Quantitative data, including prescription drug dispensing data (September 2009–August 2010) linked with Nursing Home Compare data (April 2011), were used to determine facility-level prevalence of atypical antipsychotic use, facility-level characteristics, NH staffing and NH quality. Qualitative data, including semi-structured interviews and surveys of NH leaders conducted in the first quarter of 2011, were used to determine encounters with pharmaceutical marketing. RESULTS Leadership at 46.3% of NHs (19/41) reported pharmaceutical marketing encounters, consisting of educational training, written/Internet-based materials and/or sponsored training. No association was detected between the level of atypical antipsychotic prescribing and reports of any pharmaceutical marketing by at least one NH leader. CONCLUSION NH leaders frequently encounter pharmaceutical marketing through a variety of ways, although the impact on atypical antipsychotic prescribing is unclear. PMID:25688605

  10. Cutaneous and Subcutaneous Metastases From Atypical Laryngeal Carcinoids

    Wang, Kui-Rong; Jia, Yuan-Jing; Zhou, Shui-Hong; Wang, Qin-Ying; Bao, Yang-Yang; Feng, Zhi-Ying; Yao, Hong-Tian; Fan, Jun


    Abstract The incidence of cutaneous and subcutaneous metastases from atypical laryngeal carcinoids is approximately 20%. However, the pathogenesis and natural history of, and prognostic factors for, the condition remain poorly understood. We reported a 54-year-old female presented with cutaneous and subcutaneous metastases from atypical laryngeal carcinoid. Laryngoscopy revealed a 0.5 × 1.5-cm reddish mass on the laryngeal surface of the epiglottis. Under general anesthesia, a biopsy sample was obtained via suspension laryngoscopy. Routine pathology revealed atypical laryngeal carcinoid. Immunohistochemical staining of the sections of primary tumor was positive for cytokeratin, chromogranin A, synaptophysin, hypoxia-inducible factor-1α, P53, and CD56. GLUT-1, p-Akt, and PI3K were negative. The Ki-67 index was 15%. Supraglottic laryngectomy and selective right-neck dissection were performed. After 6 months, the patient complained of pain in the right wall of the chest; multiple cutaneous and subcutaneous nodules were evident at that site and in the abdomen. An abdominal nodule was biopsied and pathology revealed that the atypical metastatic carcinoid had metastasized to both cutaneous and subcutaneous areas of the abdomen. Chemotherapy was then prescribed. Currently, the intrathecal drug delivery system remains in place. No local recurrence has been detected. Furthermore, we systematically reviewed clinical manifestations of the disease, pathogenesis, prognostic factors, and treatment. The metastasis rate (cutaneous and subcutaneous) was approximately 12.2%. Thirty patients (62.5%) with cutaneous and subcutaneous metastases exhibited contemporaneous lymph node invasion. The 3-, 5-, and 10-year survival rates were 44.0%, 22.0%, and 13.0%, respectively. The prognosis of patients with atypical laryngeal carcinoids was poor. Relevant prognostic factors included the level of p53, human papilloma virus status, certain hypoxic markers, and distant metastasis. No

  16. Transient partial growth hormone deficiency due to zinc deficiency.

    Nishi, Y; Hatano, S; Aihara, K; Fujie, A; Kihara, M


    We present here a 13-year-old boy with partial growth hormone deficiency due to chronic mild zinc deficiency. When zinc administration was started, his growth rate, growth hormone levels, and plasma zinc concentrations increased significantly. His poor dietary intake resulted in chronic mild zinc deficiency, which in turn could be the cause of a further loss of appetite and growth retardation. There was also a possibility of renal zinc wasting which may have contributed to zinc deficiency. Zinc deficiency should be carefully ruled out in patients with growth retardation. PMID:2708733

  17. Iron deficiency and cognitive functions

    Jáuregui-Lobera I


    Full Text Available Ignacio Jáuregui-Lobera Department of Nutrition and Bromatology, Pablo de Olavide University, Seville, Spain Abstract: Micronutrient deficiencies, especially those related to iodine and iron, are linked to different cognitive impairments, as well as to potential long-term behavioral changes. Among the cognitive impairments caused by iron deficiency, those referring to attention span, intelligence, and sensory perception functions are mainly cited, as well as those associated with emotions and behavior, often directly related to the presence of iron deficiency anemia. In addition, iron deficiency without anemia may cause cognitive disturbances. At present, the prevalence of iron deficiency and iron deficiency anemia is 2%–6% among European children. Given the importance of iron deficiency relative to proper cognitive development and the alterations that can persist through adulthood as a result of this deficiency, the objective of this study was to review the current state of knowledge about this health problem. The relevance of iron deficiency and iron deficiency anemia, the distinction between the cognitive consequences of iron deficiency and those affecting specifically cognitive development, and the debate about the utility of iron supplements are the most relevant and controversial topics. Despite there being methodological differences among studies, there is some evidence that iron supplementation improves cognitive functions. Nevertheless, this must be confirmed by means of adequate follow-up studies among different groups. Keywords: iron deficiency, anemia, cognitive functions, supplementation

  18. Atypical depression in the structure of organic mental disorders (literature review

    Leonov S.F.


    Full Text Available The review of literature presents current data on cli¬nical picture and diagnostics of atypical depression. Rubric “atypical depression” includes a variety of depressive states characterized by reactively caused changes of mood, sensitivity to interpersonal contacts, inverted vegetative and somatic symptoms such as increased appetite and hypersomnia. The article considers the place of atypical depression in the structure of organic mental disorders. Positions of foreign authors that produce atypical depression as a clinical entity in the structure of Bipolar affective disorder II type are represented, the views of other authors on the structure of atypical depression are considered. The analysis of national concept of non-circular depression is carried out. Questions of atypical affective conditions acquire special significance due to preparation of International Classification of Diseases of the 11th revision, because inclusion in it of Bipolar affective disorder II type, a manifestation of which is considered to be atypical depressions, is under discussion.

  19. Biotin and biotinidase deficiency

    Zempleni, Janos; Hassan, Yousef I.; Wijeratne, Subhashinee SK


    Biotin is a water-soluble vitamin that serves as an essential coenzyme for five carboxylases in mammals. Biotin-dependent carboxylases catalyze the fixation of bicarbonate in organic acids and play crucial roles in the metabolism of fatty acids, amino acids and glucose. Carboxylase activities decrease substantially in response to biotin deficiency. Biotin is also covalently attached to histones; biotinylated histones are enriched in repeat regions in the human genome and appear to play a role...

  20. Successful treatment of neonatal atypical hemolytic uremic syndrome with C5 monoclonal antibody.

    Anastaze Stelle, K; Gonzalez, E; Wilhelm-Bals, A; Michelet, P-R; Korff, C M; Parvex, P


    Hemolytic uremic syndrome (HUS) is rare in neonates. We report the case of atypical HUS (aHUS) revealed by neonatal seizures. This 18-day-old baby presented with repeated clonus of the left arm and eye deviation. Four days earlier, she had suffered from gastroenteritis (non-bloody diarrhea and vomiting without fever). Her work-up revealed hemolytic anemia (120g/L), thrombocytopenia (78g/L), and impaired renal function (serum creatinine=102μmol/L) compatible with the diagnosis of HUS. Levels of C3 and C4 in the serum were normal. Shiga-toxin in the stools as well as the IgM and IgG against Escherichia coli O157 were negative. ADAMTS 13 deficiency, inborn error of the cobalamin pathway, deficiency in the H and I protein, and factor H antibodies were excluded and we concluded in aHUS. Genetic screening of the alternative complement pathway was normal. Cerebral magnetic resonance imaging performed after 24h and 1week showed restricted diffusion areas with periventricular white matter ischemic-hemorrhagic lesions. Extensive infectious work-up was negative. Upon admission the baby received antiepileptic drugs and 2days later C5 monoclonal antibody (eculizumab) and two transfusions of packed erythrocytes because the hemoglobin value had dropped to 55g/L. The platelet value was minimal at 30g/L. Renal function normalized in 48h without dialysis and neurological examination was normal in 1week. She was discharged from the hospital at day 10 with eculizumab perfusions (300mg) planned every 3weeks. After 24months, she was relapse-free and seizure-free, with a normal neurological examination.

  3. CT diagnosis of appendicitis with atypical clinical features

    Objective: To investigate the value of CT in diagnosis of appendicitis with atypical clinical features. Methods: CT manifestations of 20 cases of appendicitis, which were not initially considered on clinical presentation, confirmed surgically and pathologically were retrospectively analyzed. Results: The CT findings of appendicitis included: (1) The appendix enlarged in diameter, with wall thickening and enhancement after administration of IV contrast material (7 cases), presence of appendicolith in 4 cases. (2) pericecal inflammation (14 cases). (3) Localized abscess of right lower quadrant (11 cases), calcified appendicolith seen in 2 cases. CT misdiagnosed 2 cases as tumour of ascending colon, and another 2 cases as pelvic inflammatory disease. Conclusions: The clinical diagnosis of appendicitis is very difficult when patients present with atypical signs and symptoms, but in most cases, the correct diagnosis of appendicitis could be made on the basis of CT findings




    Full Text Available A growing skull fracture (GSF or craniocerebral erosion or leptomeningeal cyst, is characterized by progressive diastatic enlargement of fracture line. Growing skull fracture is a rare neurological complication and ac counts for 1.2 - 1.6% of the head injury patients. GSF is generally seen in children less than 3 year of age. Authors present an atypical case of growing skull fracture in comminuted type of skull fracture which was timely and successfully managed with very good outcome. Atypical presentation, risk factors, etiopathogenesis, management and outcome in GSF is discussed along with review of literature. Delayed diagnosis and improper treatment could worsen this condition while timely surgical intervention can hav e excellent outcome.

  5. Atypical form of cat scratch disease in immunocompetent patient

    Kojić Miroslav


    Full Text Available Introduction. Cat scratch disease (CSD is an acute infectious disease with benign course caused by the bacteria Bartonella henselae. Clinically, it is usually manifested as regional lymphadenopathy and mild infective syndrome. Rare forms of the disease which usually occur in immunocompromised presons are: encephalitis, transverse myelitis, neuroretinitis, granulomatosus conjunctivitis, arthritis, hepatitis etc. Case report. We presented an atypical form of cat scratch disease in a young immunocompetent female person. The disease was manifested with prolonged fever, rash, purulent lymphadenitis and hepatitis. The diagnosis was based on characteristic patohystological finding and exclusion of the other causes of lymphadenopathy. The patient was treated by antibiotics for a few weeks, with surgical incision and drainage of the purulent lymphadenitis. Conclusion. Atypical forms of CSD could be an important differential-diagnostic problem, especially if there is no opportunity for serological confirmation of the disease.

  6. [The atypical course of syphilis in HIV infection].

    Mahrle, G; Rasokat, H; Kurz, K; Steigleder, G K


    We report on 3 HIV patients showing atypical courses of syphilis. Both the history and serology of the first patient proved a recent re-infection with T. pallidum, whereas the histopathological findings corresponded to an advanced stage of the disease (S II-III). The second patient showed the clinical picture of syphilis maligna with slowly converting and slightly positive serological reactions. The third patient had a refractory syphilis and an early relapse. Our observations suggest that syphilis might take an unusual course in HIV patients. Considering our total HIV clientèle (800 patients greater than or equal to WR 2) the frequency of these atypical cases must be rated very low (0.38%). PMID:2741530

A 23-year-old-female presented with visual acuity deterioration in her right eye accompanied by photopsia bilaterally. Corrected distance visual acuity at presentation was 20/50 in the right eye and 20/20 in the left eye. Fundus examination was unremarkable. Visual field (VF testing revealed a large scotoma. Pattern and full-field electroretinograms (PERG and ERG revealed macular involvement associated with generalized retinal dysfunction. Electrooculogram (EOG light rise and the Arden ratio were within normal limits bilaterally. The patient was diagnosed with AZOOR due to clinical findings, visual field defect, and ERG findings. Conclusion. This is a case of AZOOR with characteristic VF defects and clinical symptoms presenting with atypical EOG findings.

  8. Magnetic field in atypical prominence structures: Bubble, tornado and eruption

    Levens, P J; Ariste, A López; Labrosse, N; Dalmasse, K; Gelly, B


    Spectropolarimetric observations of prominences have been obtained with the THEMIS telescope during four years of coordinated campaigns. Our aim is now to understand the conditions of the cool plasma and magnetism in `atypical' prominences, namely when the measured inclination of the magnetic field departs, to some extent, from the predominantly horizontal field found in `typical' prominences. What is the role of the magnetic field in these prominence types? Are plasma dynamics more important in these cases than the magnetic support? We focus our study on three types of `atypical' prominences (tornadoes, bubbles and jet-like prominence eruptions) that have all been observed by THEMIS in the He I D_3 line, from which the Stokes parameters can be derived. The magnetic field strength, inclination and azimuth in each pixel are obtained by using the Principal Component Analysis inversion method on a model of single scattering in the presence of the Hanle effect. The magnetic field in tornadoes is found to be more ...

  9. Combined Papillated Bowen Disease and Clear Cell Atypical Fibroxanthoma

    Dimas Suárez-Vilela


    Full Text Available We describe a case of papillated Bowen disease (PBD, associated with a clear cell atypical fibroxanthoma (CCAFXA. The epidermal lesion showed a bowenoid papillomatous growth pattern with histologic features suggestive of infection by human papilloma virus (HPV. In the dermis a neoplasm made up by spindled or polygonal cells with wide clear cytoplasm and moderate nuclear pleomorphism was found. Immunohistochemical characteristics of these two lesions were clearly different. The atypical cells of the intraepidermal proliferation were positive for AE1-AE3 anticytokeratin antibody, EMA, p16, p53 and p63. The dermal tumor was positive for vimentin, CD10, CD68, CD99, alpha-1-antitrypsin and c-kit. Histological features and immunohistochemical profile of the dermal tumor corresponded to a CCAFXA, a very uncommon neoplasm of which only 10 cases have been reported. In situ hybridization for numerous types of HPVs was negative in both lesions.

  10. Sensitivity of atypical lateral fire spread to wind and slope

    Simpson, Colin. C.; Sharples, Jason J.; Evans, Jason P.


    This study presents new knowledge of the environmental sensitivity of a dynamic mode of atypical wildland fire spread on steep lee-facing slopes. This is achieved through a series of idealized numerical simulations performed with the Weather Research and Forecasting (WRF) and WRF-Fire coupled atmosphere-fire models. The sensitivity of the atypical lateral fire spread across lee slopes is tested for a varying background wind speed, wind direction relative to the terrain aspect, and lee slope steepness. The results indicate that the lateral spread characteristics are highly sensitive to each of these environmental conditions, and there is a broad agreement with the empirical thresholds calculated for lateral spread events observed in the 2003 Canberra bushfires. A theory to explain these environmental thresholds and their apparent interdependency is presented. The results are expected to have important implications for the management of wildland fires in rugged terrain.

  11. Efficacy of plasma therapy in atypical hemolytic uremic syndrome with complement factor H mutations.

    Lapeyraque, Anne-Laure; Wagner, Eric; Phan, Véronique; Clermont, Marie-José; Merouani, Aïcha; Frémeaux-Bacchi, Véronique; Goodship, Timothy H J; Robitaille, Pierre


    Atypical hemolytic uremic syndrome (aHUS) frequently results in end-stage renal failure and can be lethal. Several studies have established an association between quantitative or qualitative abnormalities in complement factor H and aHUS. Although plasma infusion and exchange are often advocated, guidelines have yet to be established. Long-term outcome for patients under treatment is still unknown. We describe a patient who, at 7 months of age, presented with aHUS associated with combined de novo complement factor H mutations (S1191L and V1197A) on the same allele. Laboratory investigations showed normal levels of complements C4, C3 and factor H. Plasma exchanges and large-dose infusion therapy resulted in a resolution of hemolysis and recovery of renal function. Three recurrences were successfully treated by intensification of the plasma infusion treatment to intervals of 2 or 3 days. This patient showed good response to large doses of plasma infusions and her condition remained stable for 30 months with weekly plasma infusions (30 ml/kg). Long-term tolerance and efficacy of such intensive plasma therapy are still unknown. Reported secondary failure of plasma therapy in factor H deficiency warrants the search for alternative therapeutic approaches. PMID:18425537

  12. Role of the atypical vesicular glutamate transporter VGLUT3 in l-DOPA-induced dyskinesia.

    Gangarossa, Giuseppe; Guzman, Monica; Prado, Vania F; Prado, Marco A M; Daumas, Stephanie; El Mestikawy, Salah; Valjent, Emmanuel


    Parkinson's disease (PD) is characterized by the degeneration of dopaminergic neurons. The gold standard therapy relies on dopamine (DA) replacement by the administration of levodopa (l-DOPA). However, with time l-DOPA treatment induces severe motor side effects characterized by abnormal and involuntary movements, or dyskinesia. Although earlier studies point to a role of striatal cholinergic interneurons, also known as striatal tonically active neurons (TANs), in l-DOPA-induced dyskinesia (LID), the underlying mechanisms remain to be fully characterized. Here, we find that DA depletion is accompanied by increased expression of choline acetyltransferase (ChAT), the vesicular acetylcholine transporter (VAChT) as well as the atypical vesicular glutamate transporter type 3 (VGLUT3). TANs number and soma size are not changed. In dyskinetic mice, the VAChT levels remain high whereas the expression of VGLUT3 decreases. LID is attenuated in VGLUT3-deficient mice but not in mice bearing selective inactivation of VAChT in TANs. Finally, the absence of VGLUT3 is accompanied by a reduction of l-DOPA-induced phosphorylation of ERK1/2, ribosomal subunit (rpS6) and GluA1. Our results reveal that VGLUT3 plays an important role in the development of LID and should be considered as a potential and promising therapeutic target for prevention of LID. PMID:26711621

  13. GM2-ganglioside metabolism in hexosaminidase A deficiency states: determination in situ using labeled GM2 added to fibroblast cultures

    To clarify the relationship between hexosaminidase A (HEX A) activity and GM2-ganglioside hydrolysis in atypical clinical situations of HEX A deficiency, we have developed a simple method to assess GM2-ganglioside metabolism in cultured fibroblasts utilizing GM2 labeled with tritium in the sphingosine portion of the molecule. The radioactive lipid is added to the media of cultured skin fibroblasts, and after 10 days the cells are thoroughly washed, then harvested, and their lipid composition analyzed by HPLC. The degree of hydrolysis of the ingested GM2 is determined by comparing the amount of radioactive counts recovered in undegraded substrate with total cellular radioactivity. A deficiency in GM2-ganglioside hydrolysis was demonstrated in seven HEX A-deficient adults with neurological signs and in two healthy-appearing adolescents with older affected siblings. In each case, an analysis of endogenous monosialoganglioside composition revealed an increase in GM2-ganglioside, confirming the presence of a block in the metabolism of GM2. No defect in GM2-catabolism was found in four other healthy individuals with HEX A deficiency. This method of assay is especially helpful in the evaluation of atypical cases of HEX A deficiency for the definitive diagnosis of GM2-gangliosidosis

  19. Childhood atypical meningioma with perineural spread: MR findings

    Wei, Feng-Yu.; Wong, Alex Mun-Ching; Wong, Ho-Fai; Ng, Shu-Hang [Chang Gung Memorial Hospital, Department of Diagnostic Radiology, Kwei-Shan, Tao-Yuan (Taiwan); Wu, Chieh-Tsai [Chang Gung Memorial Hospital, Department of Neurosurgery, Kwei-Shan, Tao-Yuan (Taiwan); Lin, Kuang-Lin [Chang Gung Memorial Hospital, Division of Pediatric Neurology, Kwei-Shan, Tao-Yuan (Taiwan)


    Meningiomas are uncommon in children. When they occur, they are frequently associated with neurofibromatosis type 2. Childhood meningiomas are generally large and commonly associated with cyst formation and an unusual location. Perineural tumor spread, occasionally associated with head and neck malignancies, is very rare in meningiomas. We present the MR findings of an atypical meningioma with perineural spread in a 4.5-year-old girl. (orig.)

  20. Epithelioid Schwannomas: An Analysis of 58 Cases Including Atypical Variants.

    Hart, Jesse; Gardner, Jerad M; Edgar, Mark; Weiss, Sharon W


    The histologic features and outcome of 58 cases of epithelioid schwannoma were studied to determine the significance of atypical histologic features. Cases were retrieved from personal consultation files from 1999 to 2013. Patients (31 male and 26 female patients) ranged in age from 14 to 80 years (median, 38 y). Two patients had schwannomatosis 1. Tumors developed in the dermis/subcutis (n=56) or muscle (n=2) of the upper extremity (34.5%), lower extremity (34.5%), thorax/abdomen/back (18%), and less common anatomic locations including the scalp, neck, lip, and breast. They ranged in size from 0.25 to 4.5 cm (median, 2.0 cm). Typically circumscribed and surrounded by a perineurium, they comprised single or small groups of epithelioid schwann cells with a moderate amphophilic cytoplasm and occasional nuclear pseudoinclusions. Stroma varied from myxoid to hyalinized, often with thick-walled vessels (55 cases). Mitotic rate ranged from 0 to 9 mitoses/10 high-power field (HPF) (2.37 mm) in the most active areas (mean, 2 to 3 mitoses/10 HPFs). Thirteen cases (22%) were "atypical," defined by a high mitotic rate (≥3 mitoses per 10 HPFs) and nuclear size variation (≥3:1). All (56/56) expressed S100 protein; type IV collagen invested groups or individual cells (16/17). Melanoma markers were negative, except for melan A (1 case). Follow-up in 39 patients (median, 78 mo; range, 6 to 174 mo) indicated that 31 (79%) were alive without disease (including 9/13 atypical cases; median, 78 mo), 7 (18%) were alive with unknown status, and 1 patient had died of unrelated causes. One tumor recurred, but none metastasized. Epithelioid schwannomas, even those with atypical features, are benign and do not constitute a histologic continuum with epithelioid malignant peripheral nerve sheath tumors, which typically occur in deep soft tissues and have more anaplastic features.

  4. Atypical Attentional Networks and the Emergence of Autism

    Keehn, Brandon; Müller, Ralph-Axel; Townsend, Jeanne


    The sociocommunicative impairments that define autism spectrum disorder (ASD) are not present at birth but emerge gradually over the first two years of life. In typical development, basic attentional processes may provide a critical foundation for sociocommunicative abilities. Therefore early attentional dysfunction in ASD may result in atypical development of social communication. Prior research has demonstrated that persons with ASD exhibit early and lifelong impairments in attention. The p...

  5. Early adjuvant radiotherapy in the treatment of atypical meningioma.

    Jenkinson, Michael D; Waqar, Mueez; Farah, Jibril Osman; Farrell, Michael; Barbagallo, Giuseppe M V; McManus, Robin; Looby, Seamus; Hussey, Deirdre; Fitzpatrick, David; Certo, Francesco; Javadpour, Mohsen


    Atypical meningiomas have a greater propensity to recur than benign meningiomas and the benefits of early adjuvant radiotherapy are unclear. Existing studies report conflicting results. This retrospective cohort study evaluated the role of early adjuvant radiotherapy following surgical resection of atypical meningioma. A triple center case-note review of adults with newly-diagnosed atypical meningiomas between 2001 and 2010 was performed. Pathology diagnosis was made according to the World Health Organization classification in use at the time of surgery. Patients with multiple meningiomas, neurofibromatosis type 2 and radiation-induced meningiomas were excluded. Extent of resection was defined as gross total resection (GTR; Simpson Grade I-III) or subtotal resection (STR; Simpson Grade IV-V). Survival analysis was performed using the Kaplan-Meier method. One hundred thirty-three patients were identified with a median age of 62years (range 22-86years) and median follow-up of 57.4months (range 0.1-152.2months). Tumors were mostly located in the convexity (50.4%) or falcine/parasagittal regions (27.1%). GTR (achieved in 85%) was associated with longer progression free survival (PFS) (5year PFS 81.2% versus 40.08%, log-rank=11.117, p=0.001) but not overall survival (OS) (5year OS 76.6% versus 39.7%, log-rank=3.652, p=0.056). Following GTR, early adjuvant radiotherapy was administered to 28.3% of patients and did not influence OS (5year OS 77.0% versus 75.7%, log-rank=0.075, p=0.784) or PFS (5year PFS 82.0% versus 79.3%, log-rank=0.059, p=0.808). Although extent of resection emerged as an important prognostic variable, early adjuvant radiotherapy did not influence outcome following GTR of atypical meningiomas. Prospective randomized controlled trials are planned. PMID:26775147

  8. Elevated rates of atypical handedness in paedophilia: theory and implications.

    Fazio, Rachel L; Lykins, Amy D; Cantor, James M


    Multiple factors determine handedness including genetics, prenatal stress and post-natal environmental conditions. Atypical handedness, whether manifest as increased sinistrality or decreased strength of lateral preference, has been noted in a wide variety of populations with neuropathology. Those with atypical sexual preferences, specifically paedophilia, also manifest reduced rates of right-handedness. This paper uses the largest sample of phallometrically assessed men to date to establish the pattern of atypical handedness in paedophilia. Specifically, whereas prior research has largely characterized participants dichotomously as right-handed or non-right-handed and/or used self-report of writing hand, this paper expands upon such reports by using the Edinburgh Handedness Inventory's laterality quotient. Participants' handedness and phallometrically assessed sexual preference were analyzed both as continuous and categorical variables, and the responses of those scoring in the range of ambiguous-handedness were evaluated to ascertain whether they were ambiguously handed or more accurately described as mixed-handed. Results indicated those producing scores in the range of ambiguous-handedness demonstrated response patterns consistent with ambiguous-handedness, rather than mixed-handedness. Paedophiles demonstrated high rates of non-right-handedness primarily manifested as sinistrality, whereas those who had a sexual preference for pubescent children evidenced increased ambiguous-handedness. Results support a view of ambiguous-handedness as less pathological than previously hypothesized, and of a neurodevelopmental origin of paraphilic sexual preferences. PMID:24666135

    Parvaneh KARIMZADEH


    Full Text Available ObjectiveGuillain-Barre syndrome (GBS is an immune-mediated polyneuropathy that occurs mostly after prior infection. The diagnosis of this syndrome is dependent heavily on the history and examination, although cerebrospinal fluid analysis and electrodiagnostic testing usually confirm the diagnosis. This is a retrospective study which was performed to investigate the atypical features of GBS.Materials & MethodsThirty three patients (21/63.6% males and 12/36.4% females with GBS were retrospectively studied and prospectively evaluated at the Child Neurology institute of Mofid Children Hospital of Shahid Beheshti University of Medical Sciences between May 2011 and September 2012.ResultsThe mean age was 5.4 years (range, 1.5-10.5.Twenty one patients (87.9 % had previous history of infections.

Cranial nerve involvement was found in 8(24.3% children, most commonly as facial palsy in 3 (9.1%.ConclusionIn this study, 24.3% of our patients presented with atypical symptoms of GBS as upper limb weakness, ptosis, neck stiffness, inability to stand (proximal weakness, headache and dysphagia

  10. Atypical full-field digital mammographic findings of breast cancer

    Objective: To evaluate the diagnostic significance of full-field digital mammography (FFDM) for atypical breast cancer findings. Methods: Seven hundred-eighteen cases with breast cancer were examined using FFDM and atypical mammographic findings were found in 134 cases. Craniocaudal (CC) view and mediolateral oblique (MLO) view were conducted for each patient. Mediolateral view or spot view was achieved if necessary. Preoperative localization was conducted for the patients with nonpalpable breast cancers. Results: (1) The masses with well-circumscribed margin on mammography were more common in infiltrating ductal carcinoma (22/106), mucinous carcinoma (8/10), medullary carcinoma (5/6), and increased with age and reduction of the mass density. (2) Long spiculation, architectural distortion, patchy high density were mainly found in infiltrating ductal carcinoma and 30-40 (24 cases), 41-50 (34 cases) years old patients. Long speculation was mainly found in 30-40 years old patients (10/30). (3) High homogenous density and subcutaneous edema in the entire breast and mass-like area were most frequently found in infiltrating ductal carcinoma at 30-40 (2 cases)and 41-50 (5 cases) years old. High density and subcutaneous edema were only found in dense breast (8 cases). Conclusion: The atypical findings of breast cancer in full-field digital mammography are associated with the pathological type of cancer, patient age and the gland density of the breast. (authors)

  11. Rotational velocities of A-type stars. III. Velocity distributions

    Royer, F.; Zorec, J.; Gómez, A. E.


    Aims:A sample of v sin i of B9 to F2-type main sequence single stars has been built from highly homogeneous {v sin i} parameters determined for a large sample cleansed of objects presenting the Am and Ap phenomenon as well as of all known binaries. The aim is to study the distributions of rotational velocities in the mass range of A-type stars for normal single objects. Methods: Robust statistical methods are used to rectify the {v sin i} distributions for the projection effect and the error distribution. The equatorial velocity distributions are obtained for about 1100 stars divided in six groups defined by the spectral type, under the assumption of randomly orientated rotational axes. Results: We show that late B and early A-type main-sequence stars have genuine bimodal distributions of true equatorial rotational velocities probably due to angular momentum loss and redistribution that the star underwent before reaching the main sequence. A striking lack of slow rotators is noticed among intermediate and late A-type stars.

  12. Atypical features of nanophthalmic macula- a spectral domain OCT study

    Rao Aparna


    Full Text Available Abstract Background To report atypical features on Spectral domain optical coherence tomography (SD-OCT in a case of non-familial pure adult nanophthalmos. Case presentation A 39 year old male hyperope was found to have biometric and fundus findings typical of nanophthalmos. The additional atypical features included serous pigment epithelial detachment (PED in right eye and a cuff of subretinal fluid with underlying yellow deposits along superotemporal arcade in the left eye. Fundus flourescein angiogram showed hyperfluorescence due to window defect, dye pooling due to serous PED in right eye and leak superior to disc in right eye and superotemporally in left eye. Cirrus-SD OCT horizontal line scan passing through the fovea showed extensive inner limiting membrane corrugations causing distorted foveal contour in both eyes. A large juxtafoveal serous PED and a small extrafoval PED were seen with folds in the retinal pigment epithelium (RPE-choriocapillary layer in the right eye. Conclusion Structural disruptions in the RPE-choriocapillary complex in the form of folds or juxtafoveal serous PED and RPE folds can be atypical features of nanophthalmic macula better discerned on high resolution OCT.

  13. Evidence for Broadening Criteria for Atypical Depression Which May Define a Reactive Depressive Disorder

    Brett Silverstein


    Full Text Available Objective. Arguing that additional symptoms should be added to the criteria for atypical depression. Method. Published research articles on atypical depression are reviewed. Results. (1 The original studies upon which the criteria for atypical depression were based cited fatigue, insomnia, pain, and loss of weight as characteristic symptoms. (2 Several studies of DSM depressive criteria found patients with atypical depression to exhibit high levels of insomnia, fatigue, and loss of appetite/weight. (3 Several studies have found atypical depression to be comorbid with headaches, bulimia, and body image issues. (4 Most probands who report atypical depression meet criteria for “somatic depression,” defined as depression associated with several of disordered eating, poor body image, headaches, fatigue, and insomnia. The gender difference in prevalence of atypical depression results from its overlap with somatic depression. Somatic depression is associated with psychosocial measures related to gender, linking it with the descriptions of atypical depression as “reactive” appearing in the studies upon which the original criteria for atypical depression were based. Conclusion. Insomnia, disordered eating, poor body image, and aches/pains should be added as criteria for atypical depression matching criteria for somatic depression defining a reactive depressive disorder possibly distinct from endogenous melancholic depression.

  14. Atypical extraspinal musculoskeletal tuberculosis in immunocompetent patients, a reivew. Part I: atypical osteoarticular tuberculosis and tuberculous osteomyelitis

    With the resurgence of pulmonary tuberculosis and musculoskeletal tuberculosis in North America and Europe over the last 20 years, the typical pattern of extraspinal musculoskeletal tuberculosis has been changing; presentation of the disease often mimics that of neoplasia. However, certain radiographic features may offer some clues to the more benign nature of the process and its inflammatory and infectious nature. Although the diagnosis of extraspinal musculoskeletal tuberculosis depends largely on clinical context, it is the radiologist's role to guide the imaging workup to initiate the specific treatment as early as possible. As in classic extraspinal tuberculosis, delayed diagnosis may lead to deformity of the involved joint and permanent disability. This review considers atypical osteoarticular tuberculosis and tuberculous osteomyelitis. We discuss examples of these atypical presentations. All patients were permanent residents in Europe and North America, and all were immunocompetent. (author)

  15. Treatment of carnitine deficiency.

    Winter, S C


    Carnitine deficiency is a secondary complication of many inborn errors of metabolism. Pharmacological treatment with carnitine not only corrects the deficiency, it facilitates removal of accumulating toxic acyl intermediates and the generation of mitochondrial free coenzyme A (CoA). The United States Food and Drug Administration (US FDA) approved the use of carnitine for the treatment of inborn errors of metabolism in 1992. This approval was based on retrospective chart analysis of 90 patients, with 18 in the untreated cohort and 72 in the treated cohort. Efficacy was evaluated on the basis of clinical and biochemical findings. Compelling data included increased excretion of disease-specific acylcarnitine derivatives in a dose-response relationship, decreased levels of metabolites in the blood, and improved clinical status with decreased hospitalization frequency, improved growth and significantly lower mortality rates as compared to historical controls. Complications of carnitine treatment were few, with gastrointestinal disturbances and odour being the most frequent. No laboratory or clinical safety issues were identified. Intravenous carnitine preparations were also approved for treatment of secondary carnitine deficiency. Since only 25% of enteral carnitine is absorbed and gastrointestinal tolerance of high doses is poor, parenteral carnitine treatment is an appealing alternative therapeutic approach. In 7 patients treated long term with high-dose weekly to daily venous boluses of parenteral carnitine through a subcutaneous venous port, benefits included decreased frequency of decompensations, improved growth, improved muscle strength and decreased reliance on medical foods with liberalization of protein intake. Port infections were the most troubling complication. Theoretical concerns continue to be voiced that carnitine might result in fatal arrhythmias in patients with long-chain fat metabolism defects. No published clinical studies substantiate these

  16. Carnitine palmitoyltransferase II deficiency

    Roe, C R.; Yang, B-Z; Brunengraber, H; Roe, D S.; Wallace, M; Garritson, B K.


    Background: Carnitine palmitoyltransferase II (CPT II) deficiency is an important cause of recurrent rhabdomyolysis in children and adults. Current treatment includes dietary fat restriction, with increased carbohydrate intake and exercise restriction to avoid muscle pain and rhabdomyolysis. Methods: CPT II enzyme assay, DNA mutation analysis, quantitative analysis of acylcarnitines in blood and cultured fibroblasts, urinary organic acids, the standardized 36-item Short-Form Health Status survey (SF-36) version 2, and bioelectric impedance for body fat composition. Diet treatment with triheptanoin at 30% to 35% of total daily caloric intake was used for all patients. Results: Seven patients with CPT II deficiency were studied from 7 to 61 months on the triheptanoin (anaplerotic) diet. Five had previous episodes of rhabdomyolysis requiring hospitalizations and muscle pain on exertion prior to the diet (two younger patients had not had rhabdomyolysis). While on the diet, only two patients experienced mild muscle pain with exercise. During short periods of noncompliance, two patients experienced rhabdomyolysis with exercise. None experienced rhabdomyolysis or hospitalizations while on the diet. All patients returned to normal physical activities including strenuous sports. Exercise restriction was eliminated. Previously abnormal SF-36 physical composite scores returned to normal levels that persisted for the duration of the therapy in all five symptomatic patients. Conclusions: The triheptanoin diet seems to be an effective therapy for adult-onset carnitine palmitoyltransferase II deficiency.

  17. Antithrombin deficiency in pregnancy.

    Durai, Shivani; Tan, Lay Kok; Lim, Serene


    We present a case of a 39-year-old, gravida 3 para 2, Chinese female with a history of inherited type 1 Antithrombin deficiency and multiple prior episodes of venous thromboembolism. She presented at 29+4 weeks' gestation with severe pre-eclampsia complicated by haemolysis, elevated liver enzymes and low platelet (HELLP) syndrome. She subsequently underwent an emergency caesarean section for non-reassuring fetal status, which was complicated by postpartum haemorrhage secondary to uterine atony, requiring a B-Lynch suture intraoperatively.

  18. Nasal Tip Deficiency.

    Cerkes, Nazim


    Nasal tip deficiency can be congenital or secondary to previous nasal surgeries. Underdeveloped medial crura usually present with underprojected tip and lack of tip definition. Weakness or malposition of lateral crura causes alar rim retraction and lateral nasal wall weakness. Structural grafting of alar cartilages strengthens the tip framework, reinforces the disrupted support mechanisms, and controls the position of the nasal tip. In secondary cases, anatomic reconstruction of the weakened or interrupted alar cartilages and reconstitution of a stable nasal tip tripod must be the goal for a predictable outcome. PMID:26616702

  19. Accuracy of episodic autobiographical memory in children with early thyroid hormone deficiency using a staged event

    Karen A. Willoughby


    Full Text Available Autobiographical memory (AM is a highly constructive cognitive process that often contains memory errors. No study has specifically examined AM accuracy in children with abnormal development of the hippocampus, a crucial brain region for AM retrieval. Thus, the present study investigated AM accuracy in 68 typically and atypically developing children using a staged autobiographical event, the Children's Autobiographical Interview, and structural magnetic resonance imaging. The atypically developing group consisted of 17 children (HYPO exposed during gestation to insufficient maternal thyroid hormone (TH, a critical substrate for hippocampal development, and 25 children with congenital hypothyroidism (CH, who were compared to 26 controls. Groups differed significantly in the number of accurate episodic details recalled and proportion accuracy scores, with controls having more accurate recollections of the staged event than both TH-deficient groups. Total hippocampal volumes and anterior hippocampal volumes were positively correlated with proportion accuracy scores, but not total accurate episodic details, in HYPO and CH. In addition, greater severity of TH deficiency predicted lower proportion accuracy scores in both HYPO and CH. Overall, these results indicate that children with early TH deficiency have deficits in AM accuracy and that the anterior hippocampus may play a particularly important role in accurate AM retrieval.

  20. Glucose-6-phosphatase deficiency

    Labrune Philippe


    Full Text Available Abstract Glucose-6-phosphatase deficiency (G6P deficiency, or glycogen storage disease type I (GSDI, is a group of inherited metabolic diseases, including types Ia and Ib, characterized by poor tolerance to fasting, growth retardation and hepatomegaly resulting from accumulation of glycogen and fat in the liver. Prevalence is unknown and annual incidence is around 1/100,000 births. GSDIa is the more frequent type, representing about 80% of GSDI patients. The disease commonly manifests, between the ages of 3 to 4 months by symptoms of hypoglycemia (tremors, seizures, cyanosis, apnea. Patients have poor tolerance to fasting, marked hepatomegaly, growth retardation (small stature and delayed puberty, generally improved by an appropriate diet, osteopenia and sometimes osteoporosis, full-cheeked round face, enlarged kydneys and platelet dysfunctions leading to frequent epistaxis. In addition, in GSDIb, neutropenia and neutrophil dysfunction are responsible for tendency towards infections, relapsing aphtous gingivostomatitis, and inflammatory bowel disease. Late complications are hepatic (adenomas with rare but possible transformation into hepatocarcinoma and renal (glomerular hyperfiltration leading to proteinuria and sometimes to renal insufficiency. GSDI is caused by a dysfunction in the G6P system, a key step in the regulation of glycemia. The deficit concerns the catalytic subunit G6P-alpha (type Ia which is restricted to expression in the liver, kidney and intestine, or the ubiquitously expressed G6P transporter (type Ib. Mutations in the genes G6PC (17q21 and SLC37A4 (11q23 respectively cause GSDIa and Ib. Many mutations have been identified in both genes,. Transmission is autosomal recessive. Diagnosis is based on clinical presentation, on abnormal basal values and absence of hyperglycemic response to glucagon. It can be confirmed by demonstrating a deficient activity of a G6P system component in a liver biopsy. To date, the diagnosis is most

  1. Iron Deficiency and Bariatric Surgery

    Ignacio Jáuregui-Lobera


    It is estimated that the prevalence of anaemia in patients scheduled for bariatric surgery is higher than in the general population and the prevalence of iron deficiencies (with or without anaemia) may be higher as well. After surgery, iron deficiencies and anaemia may occur in a higher percentage of patients, mainly as a consequence of nutrient deficiencies. In addition, perioperative anaemia has been related with increased postoperative morbidity and mortality and poorer quality of life aft...

    Minton, Carl Edward


    A critical first step to improving existing and designing future wide-area networks is an understanding of the load placed on these networks. Efforts to model traffic are often confounded by atypical traffic - traffic particular to the observation site not ubiquitously applicable. The causes and characteristics of atypical traffic are explored in this thesis. Atypical traffic is found to interfere with parsimonious analytic traffic models. A detection and modeling tech...
