    ABSTRACT: Background: While fine-needle aspiration cytology (FNAC) using conventional smear has been widely accepted as the primary diagnostic tool for thyroid lesions, liquid-based preparations (LBPs) are increasingly replacing it. A new automated LBP method, EASYPREP(®) (EP), was recently introduced and has shown relevant diagnostic efficacy in gynecologic samples. We compared the diagnostic utility of EP and SurePath(®) (SP), a more widely established LBP method, in thyroid FNAC. Methods: Under the ultrasonographic guidance, 253 thyroid FNAC samples were collected by sample-splitting manner. Three pathologists made cytologic diagnoses of EP and SP according to the Bethesda system independently and compared the cytomorphologic parameters. Cytohistologic correlation was performed in 30 resected cases. Results: Fifteen (5.9%) and 21 (8.3%) samples were unsatisfactory in SP and EP, respectively, owing to the unequal sample-splitting. Cytologic diagnoses of SP and EP were consistent in 228 cases (90.1%), and inconsistent in remainder mostly owing to the unequal distribution of pathognomic cells. While cytomorphologic parameters were not significantly different between two methods, EP showed less three-dimensional configuration in benign lesions. Cytohistologic correlation showed no significant differences in sensitivity (100% vs. 95.5%) and specificity (100% vs. 100%) between SP and EP. Labor time for processing 48 cases was 42% shorter with EP than with SP (28 min vs. 48 min). Conclusions: The diagnostic utility of EP in thyroid FNAC was comparable to that of SP. EP allowed better visibility owing to better fragmentation of follicular clusters. The automated system of EP has the advantages of a shorter labor time for batch processing. Diagn.

    ABSTRACT: A 29-year-old woman with systemic lupus erythematosus (SLE) presented with palpitation and neck swelling. Initial sonography showed an ill-defined hypoechoic lesion in the right thyroid gland, mentioning subacute thyroiditis. The patient received conservative care for one week. However, her neck swelling worsened and she complained of dyspnea. Follow up sonography showed marked enlargement of both thyroid glands. Irregular infiltration of hypoechoic lesions was detected along the subcapsular region of both thyroid glands. She underwent immediate intubation to secure the airway and total thyroidectomy. Histopathological staining revealed features of fungal thyroiditis with fungal hyphae characteristic of Aspergillus. There was no abnormality in the lung or paranasal sinuses. In this report, we describe the sequential sonographic findings of invasive aspergillosis in the thyroid gland presenting as progressive enlargement without other organ involvement. © 2016, Tehran University of Medical Sciences and Iranian Society of Radiology.

    ABSTRACT: The aim of this study was to evaluate the changing pattern and prognostic values of diffusion-weighted imaging (DWI) at two time points in cardiac arrest patients treated with therapeutic hypothermia. Twenty two patients with cardiac arrest who underwent two DWI studies were enrolled in the retrospective study. The first DWI was performed after the induction of therapeutic hypothermia (median 6.0hrs) and was repeated between 48hrs and 168hrs (second DWI, median 74hrs). Apparent diffusion coefficient (ADC) values were measured in the predefined brain regions, and qualitative analysis was also performed. Good neurologic outcomes were defined as Cerebral Performance Category (CPC) scores of 1 and 2. The ADC value tended to increase over time except the cortical regions of the poor outcome group (N=10). In the comparisons of receiver operating characteristic (ROC) curve to predict poor outcome using ADC value, postcentral cortex in the second DWI has a better association with neurological outcome (p=0.001, area under the curve (AUC)=0.996 for second DWI, AUC=0.571 for first DWI). In the same analysis using qualitative score, precentral cortex, postcentral cortex, parietal lobe, occipital lobe, caudate and putamen in the second DWI have a better association with neurological outcome. The changing pattern of ADC values after cardiac arrest is different according to anatomic region and neurologic status. The DWI after 48hrs has a better association with neurological outcome of cardiac arrest patients in both quantitative and qualitative analysis. Copyright © 2015. Published by Elsevier Ireland Ltd.

    ABSTRACT: Acute myelitis patients exhibiting only sensory deficits upon initial presentation are not commonly encountered in clinical practice, but they definitely exist. Since acute sensory myelitis has not been investigated previously, this study evaluated the etiological spectrum of the condition with the aim of describing the clinical characteristics thereof. Patients with acute myelitis who presented at the Ewha Womans University Medical Center (during 1999-2012) and the National Cancer Center (during 2005-2014) with only sensory symptoms as first clinical features were enrolled in this study. Their medical records, electrophysiological and laboratory data, and MRI findings were analyzed retrospectively. Of a total of 341 acute myelitis patients, 52 (15%) were identified as having acute sensory myelitis. The male-to-female ratio of these patients was 35:17, and their age at the onset of the condition was 41.7±10.5 years (mean±SD; range, 24-72 years). Acute sensory myelitis developed in patients with multiple sclerosis (MS; 14%), neuromyelitis optica spectrum disorder (NMOSD; 17%), and acute myelitis associated with concurrent systemic diseases including Behçet's disease and cancer (6%). Despite detailed evaluation, the etiology of 33 patients with acute myelitis could not be determined. Longitudinally extensive transverse myelitis on spinal MRI and progression of the sensory level were observed most commonly in NMOSD patients (89% and 78%, respectively); however, these patients did not exhibit sensory dissociation. Residual negative sensory symptoms were observed more frequently in NMOSD patients (33%) than in those with acute myelitis of unknown cause (24%) or MS (14%). During the long-term follow-up (4.7±2.7 years) of patients who did not undergo maintenance immunotherapy, a monophasic clinical course was common in those with acute myelitis of unknown cause (76%), but not in NMOSD or MS patients. Accurate identification of the diverse nature of acute sensory myelitis may assist in patient care.

    ABSTRACT: The purpose of this study was to evaluate the clinical usefulness of readout-segmented echo-planar imaging (rs-EPI) in the diagnosis of acute infarction of the brainstem and posterior fossa, by comparing its results with those of single-shot echo-planar imaging (ss-EPI) at 3-T magnetic resonance imaging. Twenty-nine patients with acute infarctions of the brainstem and posterior fossa underwent both ss-EPI and rs-EPI. Two readers independently assessed two sets of diffusion-weighted (DW) images for the qualitative comparison of image quality. Signal-to-noise ratio (SNR), lesion contrast, and contrast-to-noise ratio (CNR) were calculated for the assessment of image parameters. There were no significant differences in the conspicuity of acute infarction upon qualitative comparison; however, distinctions of anatomical structures, susceptibility artifact, the presence of uncertain high signal intensity in the brain parenchyma, and overall image quality were significantly better in rs-EPI DW images. There were no significant differences in SNR, lesion contrast, CNR, and apparent diffusion coefficient values of acute infarction and normal thalamus between rs-EPI and ss-EPI. rs-EPI DWI is a clinically useful technique for evaluating lesions in the brainstem and posterior fossa by producing high-resolution DW images with reduced susceptibility artifact. However, there are no significant differences in the conspicuity of acute infarctions in the brainstem and posterior fossa between rs-EPI and ss-EPI. Copyright © 2015. Published by Elsevier Inc.

    ABSTRACT: Diseases associated with immunoglobulin A (IgA) antibody include linear IgA dermatosis, IgA nephropathy, Celiac disease, Henoch-Schönlein purpura, etc. Although usually idiopathic, IgA antibody is occasionally induced by drugs (e.g., vancomycin, carbamazepine, ceftriaxone, and cyclosporine), malignancies, infections, and other causes. So far, only a few cases of IgA bullous dermatosis coexisting with IgA nephropathy have been reported. A 64-year-old female receiving intravenous ceftriaxone and metronidazole for liver abscess had purpuric macules and papules on her extremities. One week later, she had generalized edema and skin rash with bullae and was diagnosed with concurrent linear IgA dermatosis and IgA nephropathy. After steroid treatment, the skin lesion subsided within two weeks, and kidney function slowly returned to normal. As both diseases occurred after a common possible cause, we predict their pathogeneses are associated.

    ABSTRACT: Background/Aims: The aim of this study was to analyze the effect of BMP2 on osteogenic differentiation of human adipose tissue-derived stromal cells (hADSCs). Methods: Cultured cells were differentiated into osteogenic lineage in the presence of BMP2. Gene expressions were determined by real time PCR. Results: BMP2 increased (2/8) or inhibited (6/8) osteogenic differentiation according to hADSCs batches. Regardless of the BMP2 action on osteogenic differentiation, BMP2 induced lipid droplet formation under an osteogenic differentiation condition in all batches of hADSCs, not hBMSCs, to be tested, which was confirmed by analysis of adipogenesis related genes expression. hADSCs expressed various BMP receptors. BMP2 increased expression of BMP2-responsive genes such as DLX3 and ID2, and induced SMAD1 phosphorylation in hADSCs and hBMSCs. BMP2 increased osteogenic differentiation of hADSCs in osteogenic medium in which dexamethasone was omitted. The addition of BMP2 in the control culture media containing dexamethasone alone lead to formation of lipid droplets and increased C/EBP-alpha expression in hADSCs. In the presence of TNF-alpha, BMP2 stimulated osteogenic differentiation of hADSCs even in hADSCs batches in which treatment of BMP2 alone inhibited osteogenic differentiation. Conclusion: These data indicate that the control of osteogenesis and adipogenesis in hADSCs is closely related, and that hADSCs have preferential commitment to adipogenic lineages. (C) 2014 S.

    ABSTRACT: A 75-year-old man presented with multiple, scaly, erythematous, grouped papules, nodules and plaques with tenderness ranging from the right forearm to hand dorsum and the right lower leg for 2–3 months. Five months prior to presentation, the patient had received an antibiotic skin test on his right forearm. Lesions appeared approximately 2–3 months after the antibiotic skin test, slowly progressing without clinical improvement. Culture for fungus on the right forearm revealed growth of Scedosporium apiospermum. The tissue acid-fast bacilli (AFB) culture for the right forearm and right leg revealed growth of non-tuberculous mycobacteria which was Mycobacterium chelonae, and subsequent tissue polymerase chain reaction of both sites reported positive signs of M. chelonae. On diastase periodic acid-Schiff stain of the biopsy specimen of the right forearm, fungal hyphae were found while rod-shaped bacilli could be seen in AFB stain for the biopsy specimen of the right leg. The patient was treated with oral clarithromycin and ciprofloxacin along with an oral antifungal agent for 13 weeks. After the treatment, the lesions subsided and left a scar. We report a rare case of co-infection of S. apiospermum and M. chelonae in an immunocompetent host.

    ABSTRACT: A p-tert-octylcalix[4]arene derivative with four phenyl ketonic side arms has been synthesized as a solvent extraction reagent for precious metal ions in order to compare the extraction behavior with that of the corresponding methyl ketonic derivative of p-tert-octylcalix[4]arene in nitric acid media. The extraction efficiency of the phenyl ketonic derivative for palladium was superior to that of the methyl ketonic one over the whole nitric acid concentration range. Silver and platinum were also moderately extracted by the phenyl ketonic derivative in low nitric acid concentration. The results demonstrated that the extraction behavior of the ligands towards precious metals is related to several structural factors, such as the flexibility of the side arms, the electric charge on the carbonyl oxygen atoms and the lipophilic properties. This work also determined the extraction mechanism of palladium with the phenyl ketonic derivative of p-tert-octylcalix[4]arene based on slope analysis and the peak shift for the FT-IR spectra of the ligand before and after the metal loading. Stripping from the organic phase after forward extraction was performed to separate palladium and silver.

    ABSTRACT: A bispidine-like ligand involving four pyridine-N and three aliphatic-N donor atoms forms a bimetallic species with CuCl2 in which all seven N-donors are bound and which aggregates in the crystal through double chloride-bridging to give a tetranuclear unit. The magnetism of this solid can be interpreted in terms of a relatively weak antiferromagnetic coupling between the two Cu(ii) centres of the dinuclear subunits and a strong ferromagnetic coupling of the Cu(ii) centres in different dinuclear units involved in the bis-chlorido bridge. In solution, the assembly decays into the dinuclear subunits and, in agreement with the solid state studies, the interaction between the corresponding Cu(II) centres is shown to be primarily due to dipole-dipole coupling.

    ABSTRACT: Background/Aims: Demonstrating the molecular mechanisms of human adipose tissue-derived mesenchymal stem cells (hADSCs) differentiation and proliferation could develop hADSCs-based cell therapy. Methods: The microRNA-137 (miR-137) and cell division control protein 42 homolog (CDC42) levels were regulated by oligonucleotides transfection. The adipogenic differentiation was induced for 10 days in an adipogenic medium and assessed by using an Oil Red O stain. The regulation of miR-137 on CDC42 expression was determined by western blot, real-time PCR and luciferase reporter assay. Results: We confirmed the roles of miR-137 on hADSCs proliferation and adipogenic differentiation. We showed that overexpression of miR-137 inhibited both hADSCs proliferation and adipogenic differentiation. Overexpression of miR-137 also downregulated protein and mRNA levels of CDC42, a predicted target of miR-137. In contrast, inhibition of miR-137 with 2'-O-methyl antisense RNA increased proliferation and adipogenic differentiation in hADSCs. Luciferase reporter activity in the miR-137 target site within the CDC42 3'UTR was lower in miR-137-transfected hADSCs than in control miRNA-transfected hADSCs. RNA interference-mediated downregulation of CDC42 in hADSCs inhibited their proliferation and adipogenic differentiation. Conclusion: Our results indicate that miR-137 regulates hADSCs adipogenic differentiation and proliferation by directly targeting CDC42. These findings improve our knowledge of the molecular mechanisms governing hADSCs differentiation and proliferation. © 2014 S. Karger AG, Basel.
