#1
Oliver Jones, Richard Gooding
A young woman developed a line-associated deep vein thrombosis (DVT), which was treated with low molecular weight heparin (dalteparin). 8 days later, the DVT had significantly extended-in spite of therapeutic heparin levels. A diagnosis of heparin-induced thrombocytopenia and thrombosis (HITT) was considered, but the platelet count had not dropped. Nevertheless, a HITT assay was carried out which came back positive, with a repeat assay confirming the result. Dalteparin was stopped and apixaban treatment started, with symptomatic recovery over the following days and weeks...

Purpose: We sought to provide valid and reliable data on the acquisition of consonant sounds in speakers of Brazilian Portuguese. Method: The sample comprised 733 typically developing monolingual speakers of Brazilian Portuguese (ages 3;0-8;11 [years;months]). The presence of surface speech error patterns, the revised percentage consonants correct, and the age of sound acquisition were evaluated using phonological assessment software. The normative values for these variables were reported using means and standard deviations...

BACKGROUND: Psoriasis patients frequently switch among multiple therapies while managing their psoriasis. Determining treatment transitions is fundamental to understanding how patients access and use treatments. OBJECTIVE: We aimed to identify patterns of treatment transitions of US patients with moderate to severe psoriasis over 5 years. METHODS: This was a retrospective, longitudinal cohort study in which US patients aged ≥18 years who had at least one psoriasis claim (International Classification of Diseases, Ninth Revision [ICD-9] diagnosis) were continuously enrolled in a health plan between October 2007 and September 2012...

Levetiracetam is an antiepileptic drug used for the treatment of generalised or partial seizures, either alone or in a combination therapy. Adverse effects have been reported with its clinical use, including headache, dizziness, liver failure etc. A rare but an important adverse effect is an increase in creatine phosphokinase (CPK) levels with its use. Herein, we present a case of 43-year male, known intravenous (IV) drug abuser with a history of decompressive craniotomy. Patient presented with severe behavioural disorder for which risperidone was given...

p-hydroxyphenylacetate 3-hydroxylase from Acinetobacter baumannii catalyzes the hydroxylation of p-hydroxyphenylacetate (HPA) to yield 3,4-dihydroxyphenylacetate (DHPA). In this study, we investigated whether variants of the oxygenase component (C2) could catalyze hydroxylation of 4-hydroxyphenylethylamines to synthesize catecholamine derivatives. Single turnover product analysis showed that the R263D variant can catalyze hydroxylation of tyramine to form dopamine with the highest yield (57%). The enzyme was also found to have dual substrate charge specificity because it can also maintain reasonable hydroxylation efficiency of HPA (86%)...

Microchannels have applications in microfluidic devices, patterns for micromolding, and even flexible electronic devices. Three-dimensional (3D) printing presents a promising alternative manufacturing route for these microchannels due to the technology's relative speed and the design freedom it affords its users. However, the roughness of 3D printed surfaces can significantly influence flow dynamics inside of a microchannel. In this work, open microchannels are fabricated using four different 3D printing techniques: fused deposition modeling (FDM), stereolithography (SLA), selective laser sintering, and multi jet modeling...

A 45-year-old farmer presented with ulcers and plaques over his scrotum for the past 4 to 5 years. The condition started as a small lesion on the shaft of the penis, which improved with treatment; however, after 2 to 3 months, papulonodular lesions developed on the scrotum, which increased in size and subsequently broke down to form ulcers. He denied drug abuse but had a history of multiple unprotected sexual exposures. He was prescribed oral antibiotics, which improved the lesions, but he failed to take the antibiotics for more than a week...

Cardioversion is a class I procedure for patients with symptomatic atrial fibrillation (AF) pursuing rhythm control. There are few contemporary reports on quality of life and outcomes after cardioversion. METHODS: Using the nationwide prospective ORBIT-AF registry, cardioversion patients were propensity matched 3:1 to noncardioverted patients and Cox proportional hazards modeling evaluated hospitalization at 1 year in those with and without cardioversion. Cardiovascular outcomes, AF progression, and quality of life were evaluated for the matched cohorts with and without cardioversion...

Here, we report a case of papillary renal cell carcinoma in a 47-year-old woman. In 1970 (at 5 years old), she was diagnosed with Wilms tumor in her right kidney, and underwent surgery. However, nephrectomy was not possible. Consequently, she received radiation therapy (61. 5 Gy) at the former hospital. Thereafter, the patient regularly visited her physician and had no further problems. In 1998 (at 33 years old), blood was detected in her urine, and renal cell carcinoma was suspected. A computed tomography (CT)-guided biopsy was performed, but tissue collection was difficult due to calcification of the renal parenchyma after radiation treatment...

Methylation of lysine residues on histone tail is a dynamic epigenetic modification that plays a key role in chromatin structure and gene regulation. Members of the KDM5 (also known as JARID1) sub-family are 2-oxoglutarate (2-OG) and Fe(2+)-dependent oxygenases acting as histone 3 lysine 4 trimethyl (H3K4me3) demethylases, regulating proliferation, stem cell self-renewal, and differentiation. Here we present the characterization of KDOAM-25, an inhibitor of KDM5 enzymes. KDOAM-25 shows biochemical half maximal inhibitory concentration values of <100 nM for KDM5A-D in vitro, high selectivity toward other 2-OG oxygenases sub-families, and no off-target activity on a panel of 55 receptors and enzymes...

The relationship between allergic rhinitis and asthma is now established, and most of the clinical, epidemiological and biological data recommend integrated management. This review discusses rhinosinusitis as a co-morbid condition, a precipitating or triggering condition, and an epiphenomenon as an integrated part of the disease. A better understanding and a more pragmatic method of diagnosis and management is needed using cost-effective long-term strategies. Allergic Rhinitis, though a non-life threatening disease, its pathogenesis reveals that Bronchial Asthma also develops by the same aetiopathogenesis...

BACKGROUND: Polycystic ovary syndrome is a common cause of chronic anovulation and infertility in otherwise healthy fertile couples. Clomiphene citrate is used as a first-line ovulation induction therapy in patients with polycystic ovary syndrome. Clomiphene citrate can cause both systemic and ocular side effects. We report a rare side effect of illusory palinopsias in a patient with polycystic ovary syndrome treated with ovulation induction therapy with clomiphene citrate, and emphasize the need for gynecologists and their patients to be aware of this rare ocular side effect...

Ferrous iron can be converted to ferric iron by oxidative stress which results in the formation of methemoglobin. Consequently, the oxygen dissociation curve is shifted to the left, which leads to tissue hypoxia and ultimately may cause death. Acquired methemoglobinemia can be due to a host of offending agents and chemicals including nitrites, local anesthetics, aniline and antimalarial drugs. There are several approaches to the management of methemoglobinemia. The first step is to stop the offending agent and initiate supportive measures...
