Multiple sclerosis (MS) is a chronic central nervous system inflammatory disease of autoimmune etiology, mediated by activated T cells with evolving evidence of a significant contribution from B cells and cells of the innate immune system. The disease is thought to be due to a complex interaction between different genetic and environmental factors. The prevalence of MS is rising all over the world, due on one hand to earlier diagnosis and prolonged survival, and on the other to a true increase in incidence of the disease...

BACKGROUND: A radiopharmaceutical is a combination of a non-radioactive compound with a radioactive isotope. Two isotopes: technetium- 99m (<sup>99m</sup>Tc) and fluorine-18 (<sup>18</sup>F) are worth mentioning on the rich list of isotopes which have found numerous medical applications. Their similarity is limited only to the diagnostic area of applicability. The type and the energy of emitted radiation, the half-life and, in particular, the production method demonstrate their diversity...

Spine pain is one of the most common medical problems. Yearly incidence is reported between 15 and 45 %, lifelong is 60-90 %. Neurological examination, radiology examination, CT or magnetic resonance imaging are the basic diagnostics. Acute back pain is usually treated monotherapeutically, NSAIDs is the base. Chronic back pain treatment is multidisciplinary, it combines pharmacotherapy, physiotherapy, psychotherapy and other methods. In pharmacotherapy we proceed according to the WHO three-step ladder, including strong opioid medication for strong back pain...

PURPOSE OF REVIEW: Although Behçet's syndrome (BS) is classified as a rare disease in European countries and the USA, its neurologic involvement "neuro-Behçet's syndrome (NBS)" is commonly included in the differential diagnosis of many inflammatory and vascular central nervous system (CNS) disorders. Clinical and neuroimaging findings support two major forms of NBS: parenchymal NBS (p-NBS) and an extra-parenchymal form that presents with cerebral venous sinus thrombosis (CVST)...

OBJECTIVE: Pneumocystis pneumonia (PCP) is now predominantly observed in immunosuppressed non-HIV-infected patients. The sensitivity of the PCR is here higher than direct examination (DE) of respiratory secretions because the infection is caused by a lower inoculum of Pneumocystis jirovecii (P. jirovecii). The objective of our retrospective study was to assess the contribution of quantitative PCR (qPCR) in the diagnosis of PCP. PATIENTS AND METHODS: All patients hospitalized for PCP suspicion with a positive qPCR were included...

Kidney cystic diseases are inherited disorders causing chronic renal failure. According to the genetic defect they are classified as diseases of the primary ciliary complex and uromodulin-associated diseases. Mutations in genes coding for ciliary proteins are the basis of a broad category of genetic diseases, called ciliopathies. To date, three important ciliopathies are known: the autosomal dominant form and the recessive shape of the polycystic kidney and the nephronophthisis (NPHP). Juvenile Nephronophthisis (NPHP) is a progressive renal tubulo-interstitial disorder with a form of autosomal recessive inheritance that progresses inexorably towards terminal renal failure...

REVIEW
E Thouvenot
Multiple sclerosis (MS) is a complex heterogeneous disease. Diagnostic criteria are based on symptoms, biomarkers, MRI data and exclusion of differential diagnoses. Over the past few years, the usefulness of biomarkers has progressively decreased with the development of new MRI criteria, yet dozens of new biomarkers, especially in cerebrospinal fluid, for MS diagnosis and prognosis have been described. Large-scale studies validating some of these new biomarkers have also provided confirmation of a restricted set of biomarkers (presented here in this review) as having potential value for different stages of the disease, including as early as clinically isolated syndrome and radiologically isolated syndrome...

INTRODUCTION: The evaluation of lymph nodes and the role of groin dissection for groin sarcomas has been controversial where there have not been previous studies or guidelines published. In this study, we aim to first formulate a clinical approach in the evaluation of regional lymph nodal metastases. Second, we aim to also evaluate the role of regional lymphadenectomy in the setting of pathologically involved regional lymph nodes for groin sarcomas. MATERIALS AND METHODS: In total, 43 consecutive patients with groin sarcomas underwent treatment at the National Cancer Centre Singapore between 2002 and 2015...

Axial sesamoiditis or osteitis of the proximal sesamoid bones (PSBs) in the horse is described as a rare condition. The cause remains unknown and speculative, with vascular, infectious, and traumatic aetiologies implicated. It is specifically associated with injury of the palmar or plantar ligament (PL), also known as the intersesamoidean ligament. Imaging findings are generally rewarding and radiological changes are typical, if not pathognomonic, for the condition. Lesions consist of bone lysis at the apical to mid-body axial margins of the PSBs, with variable degrees of joint effusion...

REVIEW
Long Jiang, Jianxing He
Following the development of radiological technology, there has been an increase in the number of pulmonary nodules found. The management of pulmonary nodules represents a specific challenge to thoracic surgeons. Pulmonary nodules are small, focal, rounded radiographic opacities that may be solitary or multiple. The definite histopathologic diagnosis is crucial in determining management ranging from interval imaging to surgical resection. The choice of a particular biopsy technique depends on the risks/benefits of the procedure, the diagnostic yield, and local expertise...
