You Jin Jung, Joon-Shik Shin, Jinho Lee, Yoon Jae Lee, Me-Riong Kim, In-Hyuk Ha
Background • Large intervertebral disc herniation is often managed with surgery, but it is not uncommon for spontaneous resorption of herniated disc material to occur. Although the majority of spontaneous disc resorption occurs in the acute phase, an unusual case of delayed intervertebral disc regression at 18 mo postonset is presented. Case Presentation • A 32-y-old female patient presented with acute low-back pain and pain in both legs a Korean medicine hospital specializing in spinal disorders. Massive intervertebral disc herniation was found on lumbar magnetic resonance imaging (MRI), and inguinal and genital pain and numbness was suggestive of risk of cauda equina syndrome...

REVIEW
Doodipala Samba Reddy, Randy Volkmer
Aside from brain injury and genetic causes, there is emerging information on brain infection and inflammation as a common cause of epilepsy. Neurocysticercosis (NCC), the most common cause of epilepsy worldwide, is caused by brain cysts from the Taenia solium tapeworm. In this article, we provide a critical analysis of current and emerging information on the relationship between NCC infection and epilepsy occurrence. We searched PubMed and other databases for reports on the prevalence of NCC and incidence of epilepsy in certain regions worldwide...

Anhedonia is an important feature of major depression and schizophrenia-spectrum disorders. Few neuroimaging studies have investigated neural alterations in high anhedonia, isolated from other psychopathological variables, by including only participants without clinical diagnoses. The present study examined healthy individuals scoring high (N = 18) vs. low (N = 19) in social anhedonia, who were carefully selected from a sample of N = 282 participants. To examine differences in automatic brain responses to social-affective stimuli between high vs...

Objectification theory posits that internalization of societal perspectives about the female body leads to increased body surveillance, which can result in body-related shame and subsequent eating disorder (ED) behaviors. Preliminary research indicates that these associations may be complex in nature. This study examined temporal relations among body surveillance, body shame, and eating disorder symptoms in the context of a dissonance-based body image intervention and through 14-month follow-up. College women (N=285) completed assessments at baseline, post-intervention, and at 8-week, 8-month, and 14-month follow-up...

OBJECTIVE: Thunderclap headache and visual disturbances are typical clinical features of pituitary apoplexy (PA). Because of the acute symptomatology, many patients are referred to a neurosurgical department without prior endocrinological assessment. It is the aim of the present study to analyze initial presenting symptoms, outcome and associated endocrine disturbances in a cohort of patients with pituitary apoplexy primarily seen by neurosurgeons. PATIENTS AND METHODS: Retrospective single-center study in a neurosurgical department...

INTRODUCTION: Idiopathic intracranial hypertension (IIH) is a common cause of spontaneous cerebrospinal fluid (CSF) leaks necessitating surgical intervention, and grafting of septal, mastoid, or turbinate bone over the defect is increasingly performed to strengthen the repair of the primary defect. However, the postoperative fate of these grafted bone fragments is largely unknown. METHODOLOGY: We performed a retrospective study of patients at the University of Pennsylvania undergoing repair of spontaneous CSF leaks secondary to IIH...

This paper reports on a new boundary condition formulation to model the total coronary myocardial flow and impedance characteristics of the myocardial vascular bed for any specific patient when considered for non-invasive diagnosis of fractional flow reserve (FFR). The developed boundary condition model inherits an implicit representation of the downstream truncated vascular bed and is based on integrating patient-specific physiologic parameters that can be non-invasively extracted for each patient to account for blood flow demand to the myocardium at rest and hyperemic conditions...

Early adverse life-stress has been associated to behavioral disorders that can manifest as inappropriate or aggressive responses to social challenges. In this study, we analyzed the effects of artificial rearing on the open field and burial behavioral tests and on GFAP, c-Fos immunoreactivity and glucose metabolism measured in anxiety related brain areas. Artificial rearing of male rats was performed by supplying artificial milk through a cheek cannula and tactile stimulation, mimicking the mother's licking to rat pups from the 4(th) postnatal day until weaning...

Pulmonary challenge with the ubiquitous fungus Cryptococcus neoformans results in allergic airway inflammation (AAI) characterized by robust recruitment of eosinophils and T-cells producing type 2 cytokines to the lungs. Previous studies have demonstrated a critical role for NFκB activation within lung epithelial cells (LECs) in driving AAI in response to protein allergens, yet the role of LEC-intrinsic NFκB in promoting AAI following exposure to C. neoformans is poorly understood. To investigate the role of LEC-intrinsic NFκB in promoting AAI following C...

(223) Radium ((223) Ra) is widely used in Nuclear medicine to treat patients with osseous metastatic prostate cancer. In clinical practice (223) Ra cannot be imaged directly, however gamma photons produced by its short-lived daughter nuclides can be captured by conventional gamma cameras. In this work we show that (223) Ra and its short-lived daughter nuclides can be detected with optical imaging techniques. The light emission of (223) Ra was investigated in vitro using different setups in order to clarify the mechanism of light production...

In cancer therapy, enhanced thymidine uptake by the salvage pathway can bypass dTMP depletion, thereby conferring resistance to thymidylate synthase inhibition. We investigated whether sequential combination therapy of capecitabine and trifluridine/tipiracil (TAS-102) could synergistically enhance antitumor efficacy in colon cancer xenograft models. We also examined 3'-deoxy-3'-[(18)F]fluorothymidine ([(18)F]FLT) positron emission tomography (PET) as a means to predict therapeutic response to a sequential combination of capecitabine and trifluridine/tipiracil...

Anti-CD20 radioimmunotherapy is an effective approach for therapy of relapsed or refractory CD20pos lymphomas, but faces limitations due to poor tumor penetration and undesirable pharmacokinetics of full antibodies. Camelid single-domain Ab fragments (sdAbs) might circumvent some of the limitations of radiolabeled full antibodies. In this study, a set of hCD20-targeting sdAbs was generated and their capacity to bind hCD20 was evaluated in vitro and in vivo. A lead sdAb, sdAb 9079, was selected based on its specific tumor targeting and significant lower kidney accumulation compared to other sdAbs...

BACKGROUND: Non-invasive ventilation is sometimes unable to provide the respiratory needs of very premature infants in the delivery room. While airway obstruction is thought to be the main problem, the site of obstruction is unknown. We investigated whether closure of the larynx and epiglottis is a major site of airway obstruction. METHODS: We used phase contrast X-ray imaging to visualise laryngeal function in spontaneously breathing premature rabbits immediately after birth and at approximately 1 hour after birth...

Melioidosis is endemic in Southeast Asia and tropical Australia with varying clinical features from benign skin lesions to fatal septicaemia. Imaging plays an important role in evaluation of the melioid liver abscesses. A 45-year-old man with underlying diabetes presented with fever and lethargy for 2 weeks and abdominal pain for 2 days. His liver was enlarged on examination. Blood investigations revealed mild leucocytosis and raised liver enzymes. Ultrasound showed multiple multiloculated hypoechoic lesions throughout the liver and spleen...

The appendix is rarely present inside the inguinal hernia sac. The risk of appendicitis increases in these patients since the blood supply to the appendix can be impaired. The condition is frequently asymptomatic, and even if symptomatic it gives rise to non-specific symptoms. There is no specific laboratory finding. Diagnosis is frequently made with radiological imaging. We report two cases diagnosed as Amyand's hernia with CT.

A 54-year-old woman presented with atypical chest pain, fever and malaise. She was immunosuppressed with three agents following a living-donor kidney transplant 1 year previously. Her native kidney failure was secondary to biopsy-demonstrated crescentic IgA nephropathy, with systemic involvement. A CT pulmonary angiogram revealed an inflammatory cuff of soft tissue around the descending thoracic aorta suggesting aortitis. Inflammatory markers were elevated. Given her immunosuppression, the patient was screened extensively for infective causes and was empirically commenced on intravenous meropenem...

INTRODUCTION: Discrepancies between diffusion tensor imaging (DTI) findings and functional rating scales in amyotrophic lateral sclerosis (ALS) may be due to symptom heterogeneity, particularly coexisting cognitive-behavioural dysfunction affecting non-motor regions of the brain. Carriers of expansion mutations in the C9orf72 gene, whose motor and cognitive-behavioural symptoms span a range from ALS to frontotemporal dementia, present an opportunity to evaluate the relationship between symptom heterogeneity and DTI changes...

INTRODUCTION: Acute non-traumatic convexity subarachnoid haemorrhage (cSAH) is increasingly recognised in cerebral amyloid angiopathy (CAA). We investigated: (a) the overlap between acute cSAH and cortical superficial siderosis-a new CAA haemorrhagic imaging signature and (b) whether acute cSAH presents with particular clinical symptoms in patients with probable CAA without lobar intracerebral haemorrhage. METHODS: MRI scans of 130 consecutive patients meeting modified Boston criteria for probable CAA were analysed for cortical superficial siderosis (focal, ≤3 sulci; disseminated, ≥4 sulci), and key small vessel disease markers...
