Relapse as the commonest treatment failure through chemotherapy of child presented with acute lymphoblastic leukemia (ALL) is usually within 3 years of remission. Central nervous system (CNS) is expected as a site of extramedullary relapse in 3-8% of child leukemia, often leading to a poor prognosis. A few patients may have headache and vomiting and can be diagnosed without difficulty. However, most patients present with asymptomatic conditions. Obesity has become one of the greatest reported complications of children ALL survivors. Rarely, obesity presentation can be the first manifestation of CNS leukemia. Here, we present three unusual cases with B-ALL presentation of obesity as the first symptom at the time of CNS relapse after achieving remission. This highly localized presentation is unusual and would hopefully inform clinicians to have a high index of suspicion for relapse in children with ALL.

(CHIKV) is a mosquito-borne pathogen, within the genus of the family, that causes ~1.1 million human infections annually. CHIKV uses and mosquitoes as insect vectors. Human infections can develop arthralgia and myalgia, which results in debilitating pain for weeks, months, and even years after acute infection. No therapeutic treatments or vaccines currently exist for many alphaviruses, including CHIKV. Targeting the phagocytosis of CHIKV by macrophages after mosquito transmission plays an important role in early productive viral infection in humans, and could reduce viral replication and/or symptoms.

T-cell lymphoproliferative disease (T-LPD), characterized by primary Epstein-Barr virus (EBV) infection and clonal proliferation of T cells, occurs both in systemic and non-lymphatic organs. However, isolated indolent EBV-positive T-LPD involving the central nervous system has not been reported.

The neuron-restrictive silencer factor (NRSF), also known as repressor element 1 (RE-1) silencing transcription factor (REST) or X2 box repressor (XBR), is a zinc finger transcription factor that is widely expressed in neuronal and non-neuronal cells. It is a master regulator of the nervous system, and the function of NRSF is the basis of neuronal differentiation, diversity, plasticity, and survival. NRSF can bind to the neuron-restrictive silencer element (NRSE), recruit some co-repressors, and then inhibit transcription of NRSE downstream genes through epigenetic mechanisms. In neurogenesis, NRSF functions not only as a transcriptional silencer that can mediate the transcriptional inhibition of neuron-specific genes in non-neuronal cells and thus give neuron cells specificity, but also as a transcriptional activator to induce neuronal differentiation. Many studies have confirmed the association between NRSF and brain disorders, such as brain injury and neurodegenerative diseases. Overexpression, underexpression, or mutation may lead to neurological disorders. In tumorigenesis, NRSF functions as an oncogene in neuronal tumors, such as neuroblastomas, medulloblastomas, and pheochromocytomas, stimulating their proliferation, which results in poor prognosis. Additionally, NRSF-mediated selective targets gene repression plays an important role in the development and maintenance of neuropathic pain caused by nerve injury, cancer, and diabetes. At present, several compounds that target NRSF or its co-repressors, such as REST-VP16 and X5050, have been shown to be clinically effective against many brain diseases, such as seizures, implying that NRSF and its co-repressors may be potential and promising therapeutic targets for neural disorders. In the present review, we introduced the biological characteristics of NRSF; reviewed the progress to date in understanding the roles of NRSF in the pathophysiological processes of the nervous system, such as neurogenesis, brain disorders, neural tumorigenesis, and neuropathic pain; and suggested new therapeutic approaches to such brain diseases.

A Rathke's cleft cyst (RCC) is a common, benign, cystic disease that often leads to hypophyseal dysfunction or head symptoms. The relationship between RCCs and pituitary gland function is not clear. We therefore carried out a study to examine this relationship in greater detail.

We present a series of images of X-rays and MRI of vertebral osteomyelitis caused by in a 65-year-old patient with persistent neck pain and fever accompanied by preceding transient biliary enzymes elevation. Images detected progression of degeneration-like changes of C5-7 in three months, which is too rapid for true degeneration and relatively slow for vertebral osteomyelitis of common pathogens. Though initial imagery evaluation detected merely degenerative change, the patient was followed up monthly because of persistent fever. Three months later, the images detected the typical imagery of vertebral osteomyelitis i.e., the destruction of vertebral bone: narrowing of intervertebral spaces with focal osteosclerosis and osteolysis on C5-7 became prominent. At this point, consultation to general internal medicine was made. With grade 3 regurgitation murmur, transthoracic echocardiography was performed and revealed 14-mm-in-diameter vegetation on aortic valve. Blood cultures detected of which suspected entry was biliary tract. No previous case reports of referred to vertebral osteomyelitis. While this case showed a typical clinical course of infective endocarditis, the course of progression of vertebral osteomyelitis and perhaps endocarditis was much slower comparing to common pathogens. This might reflect the relatively non-life-threatening features of this organism. shows mild resistance to vancomycin and cephalosporins, initial therapy sometimes fails. should be newly added to pathogenic candidates of vertebral osteomyelitis especially when feverish patients shows back or neck pain with preceding biliary tract problems.

Pain and nausea and vomiting are of serious complications following the use of opiates after surgery, especially cesarean section. Control of postoperative complications is one of the necessities of quality promotion of health-care system. Medications with few side effects such as corticosteroids including dexamethasone can be an appropriate option. In addition, the route of administration can have a significant effect on the effectiveness of the drug. The aim of the present study was to compare the effects of intrathecal with intravenous dexamethasone in reducing the complications associated with intrathecal morphine after cesarean section.

Chronic abdominal pain is a frequent childhood complaint. This study aims to determine the relationship between bile reflux, which is increasing with the growth in packaged food consumption resulting from the changing food industry, and Helicobacter pylori gastritis.

We present a case report of a 26-year-old female patient with acute visual impairment, who had been treated with 50 mg/day topiramate for 5 days for migraine prophylaxis. Ocular examination showed bilateral anterior chamber narrowing and macular striae. She had no previous ocular pathology, but her cycloplegic refraction showed a myopic shift of about 6 D. Topiramate was stopped and the patient's unaided visual level and macular stria returned to normal with topical steroid and cyclopentolate treatment. Recognition of this side effect and discontinuation of the causative drug may prevent angle closure and related vision loss.

Bunting (CSB) is a perennial herb belonging to genus (Papaveraceae), called "Yan-huang-lian" in the Chinese folk. Traditionally, it is used to treat acute conjunctivitis, corneal pannus, acute abdominal pain, hemorrhoidal bleeding, haematochezia, swelling, hepatitis, cirrhosis and liver cancer based on traditional Chinese medicine (TCM) concepts. This review aims to summarize and analyze the pharmacokinetics, pharmacological and toxicological properties of CSB and its extracts; to highlight the relevance of modern pharmacology to traditional pharmacology; also to assess its therapeutic potential. CSB related literatures were searched and screened from databases including PubMed, Web of Science and CNKI. The selected literatures provided reliable source identification evidences. In traditional medicine concepts, CSB has the effects of clearing away heat and detoxification, eliminating dampness, relieving pain, and stopping bleeding. Its modern pharmacology includes hepatoprotective, anticancer, anti-inflammatory, analgesic, antibacterial, anti-oxidative effects. Further, some pharmacological effects support its traditional uses. The CSB total alkaloids (CSBTA) are the main constituents isolated from this plant, and they exert the major of the pharmacological effects. Toxicological studies have shown that the toxicity of CSBTA is mild and reversible in rodents and beagle dogs. Although the present study summarizes the botany, phytochemistry, pharmacokinetics, pharmacology, toxicity, and applications of this plant, it is still necessary to systemically evaluate the chemistry, safety and parameters related to drug metabolism of the extracts or compounds from this plant before or in clinical trials in the future. Meanwhile, cancers and inflammatory-related diseases may be new research directions of this ethnomedicine.
