Madelung deformity is a rare deformity of forearm and wrist caused by growth disorders of distal radius ulnar and palmar epiphyseal. Current studies showed that its incidence mainly associated with trauma, epiphyseal developmental abnormalities, nutritional disorders and genetic deletion or mutation. The early clinical presentation is not typical, in middle and late time, wrist deformity and weak can appear. Plain film considered as the main means of diagnosis is often lack of early diagnosis significance. Although wrist joint magnetic resonance imaging showing early soft tissue and skeletal abnormalities were used for the early diagnosis of the disease, current domestic study in magnetic resonance imaging of this deformity is less...

Haploinsufficiency of the transcription factor short stature homeobox (SHOX) manifests as a spectrum of clinical phenotypes, ranging from disproportionate short stature and Madelung deformity to isolated short stature. Here, we describe five infants with molecularly confirmed diagnoses of SHOX haploinsufficiency who presented in utero with short long bones during routine antenatal scanning from as early as 19 weeks gestation. Other foetal growth parameters were normal. The molecular basis of SHOX haploinsufficiency was distinct in each case...

A layered oxychloride Bi4NbO8Cl is a visible-light responsive catalyst for water splitting, with its remarkable stability ascribed to the highly dispersive O-2p orbitals in the valence band, the origin of which, however, remains unclear. Here we systematically investigate four series of layered bismuth oxyhalides, BiOX (X = Cl, Br, I), Bi4NbO8X (X = Cl, Br), Bi2GdO4X (X = Cl, Br) and SrBiO2X (X = Cl, Br, I) and found that Madelung site potentials of anions capture essential features of the valence band structures of these materials...

Fragment-based methods predict nuclear magnetic resonance (NMR) chemical shielding tensors in molecular crystals with high accuracy and computational efficiency. Such methods typically employ electrostatic embedding to mimic the crystalline environment, and the quality of the results can be sensitive to the embedding treatment. To improve the quality of this embedding environment for fragment-based molecular crystal property calculations, we borrow ideas from the embedded ion method to incorporate self-consistently polarized Madelung field effects...

A variety of osteotomies have been reported to correct Madelung deformity using plain radiographs. However, evaluation of the deformity using 2-dimensional plain radiography is difficult because of its complex 3-dimensional nature. Therefore, we performed corrective osteotomy using recently developed 3D simulation technology on an adult woman with Madelung deformity, and achieved an excellent outcome. In this study, we calculated the amount of parallel displacement as well as the rotational angle for more precise correction, and performed open wedge osteotomy...

Developmental neurology is one of the major areas of neuropediatrics and is among other things (legally) responsible for monitoring the motor, cognitive and psychosocial development of all infants using standardized monitoring investigations. The special focus is on infants born at risk and/or due to premature birth before 32 weeks of gestation or a birth weight less than 1500 g. Early diagnosis of deviations from normal, age-related development is a prerequisite for early interventions, which may positively influence development and the long-term biopsychosocial prognosis of the patients...

The degradation mechanism of dimethyl carbonate electrolyte dissociation on the (010) surfaces of LiCoO2 and delithiated Li1/3CoO2 were investigated by periodic density functional theory. The high-throughput Madelung matrix calculation was employed to screen possible Li1/3CoO2 supercells for models of the charged state at 4.5 V. The result shows that the Li1/3CoO2(010) surface presents much stronger attraction toward dimethyl carbonate molecule with the adsorption energy of -1.98 eV than the LiCoO2(010) surface does...

OBJECTIVES: Perfusion through leptomeningeal collateral vessels is a likely pivotal factor in the outcome of stroke patients. We aimed to investigate the effect of collateral status on outcome in a cohort of unselected, consecutive stroke patients with middle cerebral artery occlusion undergoing reperfusion therapy. MATERIALS AND METHODS: This retrospectively planned analysis was passed on prospectively collected data from 187 consecutive patients with middle cerebral artery occlusion admitted within 4...

Conceptual DFT and quantum chemical topology provide two different approaches based on the electron density to grasp chemical concepts. We present a model merging both approaches, in order to obtain physical properties from chemically meaningful fragments (bonds, lone pairs) in the solid. One way to do so is to use an energetic model that includes chemical quantities explicitly, so that the properties provided by conceptual DFT are directly related to the inherent organization of electrons within the regions provided by topological analysis...

The electronic structures of 35 A(2+)B(4+)O3 ternary cubic perovskite oxides, including their hypothetical chemical compositions, were calculated by a hybrid functional method with the expectation that peculiar electronic structures and unique carrier transport properties suitable for semiconductor applications would be hidden in high-symmetry cubic perovskite oxides. We found unique electronic structures of Si-based oxides (A = Mg, Ca, Sr, and Ba, and B = Si). In particular, the unreported cubic BaSiO3 has a very narrow band gap (4...

BACKGROUND: Madelung's disease (MD) is a rare disease of unknown etiology that is characterized by massive fatty deposits distributed in a symmetrical pattern mainly in the head, neck, and upper trunk. Here, we sought to explore the pathogeny and treatment of MD. METHODS: We enrolled ten patients who underwent surgical operations and one patient who refused an operation at our hospital between January 2009 and December 2016. We collected their medical histories and the preoperative and postoperative serological indices...

BACKGROUND: Vaginal candidiasis is frequent among pregnant women and it is treated with anti-fungal medication (conazoles). Conazoles have anti-androgenic properties and prenatal exposure in rodents is associated with a shorter (less masculine) anogenital distance (AGD) in male offspring. To our knowledge this has never been studied in humans. METHOD: In the Odense Child Cohort pregnant women residing in Odense municipality, Denmark, were recruited at gestational age 8-16 weeks between 2010 and 2012...

Madelung's disease (benign symmetric lipomatosis) is a rare syndrome in which there are multiple lipomas around the neck, upper limbs and trunk in the context of chronic alcoholism. We report on a female patient with lipomas and slightly progressive myoclonus, neuropathy, myopathy, ataxia and respiratory systemic involvement (labelled in the past as Madelung's disease). Multisystem involvement and family history of lipomas led to the development of mitochondrial genetic tests, which can assess two concurrent mitochondrial mutations: the m...

In this contribution, we propose a new simple and fast computing approach to model liquid water and water-1,4 dioxane mixture, which is intermediate between molecular dynamics calculation and lattice fluid H-bonding theory in which water molecules are arranged according to a fluctuating hexagonal Ih network. It generalizes the interstitial mixture models of Samoilov and Pauling by increasing the number of spatial configurations into the space of phases due to the addition of rotations and vibrations of the molecules around their equilibrium positions...

BACKGROUND: Madelung's disease is a rare disorder characterised by the presence of multiple, symmetric, non-capsulated fat masses in the face, neck and other areas of upper extremities. In some cases, severe clinical complications such as upper airway compression can occur. CASE REPORT: A 56-year-old man affected by Madelung's disease complained of snoring and severe daytime sleepiness. Polysomnography revealed severe obstructive sleep apnoea. An attempt to treat sleep apnoea by continuous positive airway pressure failed because of poor compliance...

BACKGROUND: During infection of the urinary tract, uropathogenic Escherichia coli (UPEC) are exposed to different environments, such as human urine and the intracellular environments of bladder epithelial cells. Each environment elicits a distinct bacterial environment-specific transcriptional response. We combined differential fluorescence induction (DFI) with next-generation sequencing, collectively termed DFI-seq, to identify differentially expressed genes in UPEC strain UTI89 during growth in human urine and bladder cells...
