INTRODUCTION: Ossifying fibromyxoid tumor (OFMT) is a rare lesion that generally occurs in the soft tissues of proximal limbs, head or neck and presents as a slowly growing mass. Abdominal or trunk locations are extremely rare. PRESENTATION OF CASE: We report a case of 50-year-old man who presented with a painless, slow growing epigastric mass for 5 years. Radiologic assessment revealed a well circumscribed median subcutaneous parietal mass lesion present in front of the xiphoid process suspicious of a calcified hydatid cyst...

BACKGROUND: Current guidelines advocate no prophylactic dissection of the lateral neck compartment for papillary thyroid carcinoma (PTC) without clinical evidence of lateral neck metastasis (cN1b). However, lateral neck recurrence can affect patient treatment outcomes and quality of life. Therefore, this study examined the risk factors for lateral neck recurrence after the definitive treatment of PTC without cN1b. METHODS: The study enrolled 1928 consecutive patients who underwent total thyroidectomy between 2006 and 2012 for PTC without cN1b...

Neurologic complications in persons with HIV infection are less severe in the era of potent antiretroviral therapy but remain highly prevalent. Prior to the use of antiretroviral therapy, opportunistic infections of the central nervous system (CNS) and CNS malignancy were common. Progressive multifocal leukoencephalopathy (PML), however, remains a diagnostic challenge in HIV-infected individuals, and no effective antiviral treatment for PML is currently available. Primary neurologic complications of acute HIV infection include aseptic meningitis and acute inflammatory demyelinating polyneuropathy...

BACKGROUND: Optic atrophy may be the sequela of optic nerve injury due to any insult, including isolated and syndromic genetic diseases. Alanyl-tRNA synthetase 2 (AARS2) pathogenic variants have been reported to cause leukodystrophy with ovarian failure, and cardiomyopathy (#615889) as well as combined oxidative phosphorylation deficiency-8 (#614096). We report a young child who presented with decreased vision due to optic atrophy and was found to harbor missense variants in the AARS2 gene expanding the phenotypic expression of the AARS2 gene...

BACKGROUND: Immature ovarian teratoma is very rare in childhood. We are reporting 12 yo female with immature ovarian teratoma who presented initially with syndrome of inappropriate antidiuretic hormone. CASE: A 12 yo female presented with acute abdomen and distention. Initial laboratory tests showed hyponatremia (sodium -123 mmol/L), that did not respond to fluid management. Computerized tomography showed a 15 cm x 9 cm x 20 cm mass in the right ovary with multifocal internal fat, and dystrophic calcifications...

PURPOSE: To test the effects of tumour size, tumour distribution and tumour grade on progression-free survival (PFS) in patients with upper tract urothelial carcinoma (UTUC) treated with flexible ureteroscopy with Holmium:YAG laser photoablation (FULP). MATERIALS AND METHODS: Data from 92 consecutive UTUC patients treated with FULP (2003-2015) at a single tertiary care referral center were included. A stringent follow-up was offered according to the European Association Urological guidelines...

SIGNIFICANCE: The amount of central or peripheral myopic shift, as induced by different multifocal contact lenses when viewing objects at distance or near, may provide insights on the potential efficacy for slowing eye growth. PURPOSE: The present study aims to compare peripheral refraction and higher-order aberration profiles of four multifocal contact lenses with a single vision control lens. METHODS: Thirty-five myopes (age 21.2 ± 2.1 years) completed the trial, of whom 16 wore Air Optix Aqua and Proclear Multifocal Distance and Near (group 1, spherical equivalent: -2...

SIGNIFICANCE: To maximize efficiency of the normally lengthy and costly multizone lens design and testing process, it is advantageous to evaluate the potential efficacy of a design as thoroughly as possible prior to lens fabrication and on-eye testing. The current work describes an ex vivo approach of optical design testing. PURPOSE: The aim of this study was to describe a system capable of examining the optical characteristics of multizone bifocal and multifocal optics by subaperture stitching using liquid crystal technologies...

OBJECTIVE: To analyze the efficiency of ureteroscope and biopsy in the diagnosis of tumor grade, muscle-invasiveness and multifocality in suspected upper tract urinary carcinoma (UTUC) patients in order to find out whether it can be used in the risk stratification of UTUC patients. METHODS: A retrospective study of 76 UTUC patients who underwent preoperative ureteroscope and/or biopsy and received radical nephroureterectomy in Peking University Third Hospital during January 2014 to December 2016 was undertaken...

Fragile-X-syndrome is the most common cause of inherited intellectual disability. Epilepsy is reported to occur in 10-20% of individuals with Fragile-X-syndrome. A frequent seizure/electroencephalogram (EEG) pattern resembles that of benign rolandic epilepsy. We describe the clinical features, EEG findings and evolution in three patients affected by Fragile-X-syndrome and epilepsy mimicking Panayiotopoulos syndrome. Age at seizure onset was between 4 and about 7 years. Seizures pattern comprised a constellation of autonomic symptoms with unilateral deviation of the eyes and ictal syncope...

BACKGROUND: Deficiency of IL-1 receptor antagonist (DIRA) is a rare autoinflammatory disease that presents with life-threatening systemic inflammation, aseptic multifocal osteomyelitis, and pustulosis responsive to IL-1-blocking treatment. This study was performed (a) to investigate rilonacept, a long-acting IL-1 inhibitor, in maintaining anakinra-induced inflammatory remission in DIRA patients, (b) to determine doses needed to maintain remission, and (c) to evaluate the safety and pharmacokinetics of rilonacept in young children (<12 years)...

BACKGROUND: The pathology of spirocercosis, a disease caused by the infestation of carnivores with the nematode Spirocerca lupi, has been extensively described in domestic dogs and coyotes. However, it has not been described in wild carnivores in South Africa. The aim of this study was to evaluate whether black-backed jackals are a host for Spirocerca species and to provide a detailed description of the associated pathology. Jackals were also stratified according to age and the Spirocerca species recovered were characterized using molecular techniques...

Purpose: To investigate the characteristics of retinal electrophysiological activity in relation to early myopia development in children. Methods: Fifty-six children aged 6 to 9 years with emmetropic refractive error (defined as ≥ -0.5 diopter [D] and ≤ +0.5 D) were recruited. Cycloplegic refraction, axial length, and global flash multifocal electroretinogram (MOFO mfERG) at 49% and 96% contrast levels were recorded in all children at their first visit. The refraction and axial length measurements were repeated after 1 year...

Dystrophia myotonica (DM) type 1 is an autosomal dominant disorder, caused by a trinucleotide CTG repeat expansion in the 3' untranslated region of the dystrophia myotonica protein kinase (DMPK) gene (chromosome 19q13.3). The disorder affects different organ systems, including the skeletal muscles, ocular lens, lungs, heart and gastrointestinal tract, as well as the endocrine and central nervous systems. The skeletal muscles are most frequently involved, whereby the disorder manifests as myotonia, muscle weakness and amyotrophy...

BACKGROUND AND OBJECTIVE: To compare patterns of choroidal hypoperfusion in white dot syndromes (WDS) using optical coherence tomography angiography (OCTA). PATIENTS AND METHODS: Consecutive patients with WDS were imaged with either the Zeiss AngioPlex OCT Angiography (Carl Zeiss AG, Oberkochen, Germany) or the AngioVue OCT Angiography (Optovue, Fremont, CA) from February to November 2016. Four patients with acute posterior multifocal placoid pigment epitheliopathy (APMPPE), birdshot chorioretinopathy (BCR), presumed ocular histoplasmosis syndrome (POHS), and multiple evanescent white dot syndrome (MEWDS) were selected...

Bleeding is the most important clinical outcome in patients with immune thrombocytopenia (ITP), and the goal of therapy in such cases is to treat or prevent bleeding. The frequency of and risk factors for bleeding events in ITP have only recently been identified in several large-scale studies. However, there is little published information about severe life-threatening bleeding in ITP. To clarify the clinical features of life-threatening bleeding in patients with primary ITP, we systematically reviewed the medical records of all ITP patients that were admitted to our hospital between January 1, 1992, and December 31, 2015...

AIMS: There is now evidence to support giving single-agent chemotherapy, radiotherapy or hypofractionated concurrent chemoradiotherapy to older patients with glioblastoma (GBM). However, the clinical basis on which treatment decisions are made is under-researched and not standardised. This retrospective, multicentre study assessed whether pre-morbid characteristics or tumour imaging features could predict for overall survival in a cohort of older patients with GBM. MATERIALS AND METHODS: Patients aged > 70 years, diagnosed with GBM at three neuro-oncology centres from 2010 to 2015 were retrospectively analysed...

Squamous odontogenic tumor is a rare benign epithelial odontogenic tumor of the jaw. Most are solitary lesions, although rare multifocal lesions have been described. Maxillary lesions have more aggressive behavior. Because of their benign character, these lesions are usually treated using a conservative surgical approach with curettage and surgical enucleation. This report describes the case of a 29-year-old woman with multifocal lesions who was initially treated with conservative surgical therapy. Early recurrence 6 months after surgery prompted more aggressive resection...

We report a woman with multifocal lesions suggestive of meningiomas in MRI, which also presented with high Ga-DOTATATE uptake in PET, a finding characteristic for meningioma. A whole-body staging due to a pathological fracture revealed multiple neoplastic lesions throughout the body without detection of a primary site. Subsequent pathological workup of a lung lesion revealed multifocal metastases from follicular thyroid cancer despite thyroidectomy 10 years ago (without pathological finding), and posttreatment scans after radioiodine therapy confirmed the multiple brain lesions to be metastases as well...
