Methylphenidate (Ritalin(®)) is an increasingly used medication in the treatment of attention-deficit hyperactivity disorder (ADHD). Cardiovascular adverse effects like vasospasm or myocardial infarction are described as very rare adverse effects. We present the case of a 21-year-old man diagnosed with ADHD who recently started therapy with Ritalin(®) Adult 20 mg for at least 3 days. Afterwards he presented with chest pain, elevated troponin and creatine kinase, and posterolateral ST elevations. A myocarditis was initially supposed...

Multifocal osteomyelitis and synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome constitute a spectrum of disease that includes inflammatory bone lesions and dermatologic findings. Radiographic features resemble those of the spondyloarthropathies with anterior chest wall involvement. Early radiographic findings are osteodestructive with lytic lesions. Bone scintigraphy of the sternoclavicular region classically yields a 'bull's head' pattern of radionuclide uptake. Magnetic resonance imaging (MRI) can demonstrate corner lesions of vertebral bodies...

BACKGROUND: 19F-MRI and 19F-MRS can identify specific cell types after in-vitro or in-vivo 19F-labeling. Knowledge on the potential to track in-vitro 19F-labeled immune cells in tumor models by 19F-MRI/MRS is scarce. AIM: To study 19F-based MR techniques for in-vivo tracking of adoptively transferred immune cells after in-vitro 19F-labeling, i.e. to detect and monitor their migration non-invasively in melanoma-bearing mice. METHODS: Splenocytes (SP) were labeled in-vitro with a perfluorocarbon (PFC) and IV-injected into non-tumor bearing mice...

The MARIA randomized trial evaluated the efficacy and safety of melatonin for the reduction of reperfusion injury in patients undergoing revascularization for ST-elevation myocardial infarction (STEMI). This was a prespecified interim analysis. A total of 146 patients presenting with STEMI within 6 hours of chest pain onset were randomized to receive intravenous and intracoronary melatonin (n=73) or placebo (n=73) during primary pecutaneous coronary intervention (PPCI). Primary endpoint was myocardial infarct size as assessed by magnetic resonance imaging (MRI) at 6±2 days...

Hydatid disease (HD) is endemic in many parts of the world. HD can affect virtually any organ system in body and should be kept as differential diagnosis of cystic lesion. HD is mostly asymptomatic; however, it demonstrates a variety of characteristic imaging findings depending on the site of involvement, stage of growth, mass effect, complications, or hematogenous spread, which helps in diagnosis. Radiography, ultrasonography (USG), computed tomography (CT), and magnetic resonance imaging (MRI) are commonly used imaging modalities...

Lung cancer is the leading cause of cancer death worldwide. Prognosis and treatment outcomes are known to be related to the disease stage at the time of diagnosis. Therefore, an accurate assessment of the extent of disease is critical to determine the most appropriate therapy. Currently available imaging modalities for diagnosis and follow-up consist of morphological and functional imaging. Morphological investigations are mainly performed with CT-scan and in some cases with MRI. In this review, we describe the contribution of MRI in lung cancer staging focusing on solid pulmonary nodule characterization and TNM staging assessment using chest and whole-body MRI examinations, detailing in each chapter current recommendations and future developments...

AIMS: Naturally secreted nanovesicles known as exosomes are required for the regenerative effects of cardiosphere-derived cells (CDCs), and exosomes mimic the benefits of CDCs in rodents. Nevertheless, exosomes have not been studied in a translationally realistic large-animal model. We sought to optimize delivery and assess the efficacy of CDC-secreted exosomes in pig models of acute (AMI) and convalescent myocardial infarction (CMI). METHODS AND RESULTS: In AMI, pigs received human CDC exosomes (or vehicle) by intracoronary (IC) or open-chest intramyocardial (IM) delivery 30 min after reperfusion...

FDG PET/CT is perceived as a valuable diagnostic tool in addition to the standard diagnostic workup for patients with isolated neck lymph nodes of squamous cell carcinoma of unknown primary (SCCUP). For patients with SCCUP intended for primary radiotherapy, we hypothesize that the previously reported FDG PET/CT detection rates are too high. From 2008 to 2015, 30 SCCUP patients were examined with FDG PET/CT. The objective of the FDG PET/CT examination was twofold: (1) improve the radiotherapy target definition, and (2) identify the primary cancer...

A young woman was examined in the Emergency Department for fever, pharyngitis and widespread petechial rash. Physical examination, including neurological evaluation, did not show any other abnormalities. Chest X-ray was negative. Blood exams showed leukocytosis and CPR 20 mg/dL (nv<0.5 mg/dL). On the basis of these results and petechial rash evidence, lumbar puncture was performed. CSF was opalescent; physico-chemical examination showed: total proteins 2.8 (nv 0.15-0.45), glucose 5 (nv 59-80), WBC 7600/μL (nv 0-4/ μL)...

Recent imaging studies using chest computed tomography (CT) in presymptomatic infants and young children with cystic fibrosis (CF) diagnosed by newborn screening presented compelling evidence of early onset and progression of structural lung damage in CF. These data argue persuasively that non-invasive outcome measures for early detection and sensitive monitoring of lung disease applicable in the clinical setting will be instrumental for further improvement of clinical care and the development of early intervention therapies that have the potential to prevent irreversible lung damage...

We report the case of a 66-year-old man with seropositive rheumatoid arthritis who developed neurologically asymptomatic rheumatoid meningitis (RM) revealed by MRI. RM worsened and chest CT showed pericardial effusion, pleural effusion, and bilateral consolidation, and his serum C3 level was decreased. We diagnosed systemic rheumatic vasculitis based on these findings. After a review of more than 20 previously reported cases of RM, this is the first case of RM without central nerve system symptoms.

BACKGROUND: MECP2 duplication syndrome, which is caused by duplication of part of the Xq28 region containing the MECP2 gene, causes intellectual disability and mild dysmorphic features in males. To date, precocious puberty has not been reported as a clinical feature of MECP2 duplication syndrome. METHODS: A 6-year-old male with severe intellectual disability was referred because of growth acceleration and precocious puberty. We checked his hormonal profile and conducted imaging studies and an array comparative genomic hybridization analysis...

According to the seventh report of Joint National Committee (JNC 7), hypertensive emergency (HE), a kind of hypertensive crisis, is defined as a sudden and abrupt elevation in blood pressure so as to cause acute target organ dysfunctions, including central nervous system, cardiovascular system or kidneys. Patients with HE require immediate reduction in markedly elevated blood pressure. Currently, there are no international guidelines for children HE, so the JNC definition is commonly used. Hypertensive emergency in children is rare but a life-threatening emergency...

CLINICAL/METHODICAL ISSUE: Granulomas as signs of specific inflammation of the lungs are found in various diseases with pulmonary manifestations and represent an important imaging finding. STANDARD RADIOLOGICAL METHODS: The standard imaging modality for the work-up of granulomatous diseases of the lungs is most often thin-slice computed tomography (CT). There are a few instances, e. g. tuberculosis, sarcoidosis and silicosis, where a chest radiograph still plays an important role...

Cystic tuberculosis of the bone is a rare form of tuberculosis (TB). The condition presents like Juvenile idiopathic arthritis (JIA) of children. In children, the lesions symmetrically involve the peripheral skeleton, which are less sclerotic than adults. A case report is presented here where the patient presented with i) the extensive involvement of bones with cystic lesion, ii) Hand & feet involvement with multiple bony exostosis iii) Synovial swelling of multiple joints and 4) fever for 6 months. Swelling of the joints was disproportionately greater than pain...
