Chemo-cytokines network is main target for control of Allergic asthma

Published on: 25th January, 2018

OCLC Number/Unique Identifier: 7347023872

Asthma is a chronic respiratory disease which characterized by recurrent airflow obstruction, wheezing, chest tightness and coughing. Management of allergic asthma especially in children, is main problem for industrial world. Immunological factors have critical role in pathogenesis of allergic asthma. Cytokines as major controller of immune system, are important in this reaction. Allergic asthma is a disease with symptoms: eosinophilic inflammation, mucus hyper secretion, airway obstruction, airways hyperresponsivness, IgE high level production, smooth muscle spasm. Cytokines have main and complicated role in pathophysiology of allergic asthma.

Knowledge, attitude and practices associated with diagnosis and management of Skin and Soft Tissue Infections (SSTIs) among Pediatric Residents and Physicians in a Tertiary Hospital in United Arab Emirates (UAE)

Published on: 11th July, 2017

OCLC Number/Unique Identifier: 7317652483

Objectives: The study aims to assess the knowledge, attitude and practices of physicians who deal with pediatric age group SSTIs in reference to the Infectious Diseases Society of America (IDSA) guidelines on this regard that was published in 2014. Background: Skin and soft tissue infections rank among the most frequent infections worldwide. It is estimated that over 11 million ambulatory healthcare visits occur each year in US for skin and soft tissue infections due to Staphylococcus aureus (S. aureus) alone. SSTIs are clinical entities of variable presentation, etiology and severity that involve microbial invasion of the layers of the skin and underlying soft tissues. SSTIs range from mild infections, such as pyoderma, to serious life-threatening infections, such as necrotizing fasciitis. One of the main challenges in managing SSTIs is to be able to identify those who need immediate inpatient intervention versus the more stable ones that can be manages in outpatient basis. In June of 2014, The Infectious Diseases Society of America (IDSA) released evidence based guidelines that has nicely covered all aspects related to the management of SSTIs. Method:An anonymous 20-item survey exploring knowledge, attitude and practices associated with diagnosis and management of skin and soft tissue infection was distributed to physicians of different levels of expertise (from residents to consultants) in the departments of Pediatrics, Emergency Medicine and Family Medicine in different governmental facilities in Al-Ain city which is one of the major cities in United Arab Emirates.

Recurrent hydrothorax due to diaphragmatic perforation post hepatocellular carcinoma radiofrequency ablation: A case report

Published on: 15th February, 2021

OCLC Number/Unique Identifier: 8979519249

Radiofrequency ablation is one of the most commonly used therapies for potentially curative small hepatocellular carcinoma. Although radiofrequency is usually a safe procedure, severe and potentially fatal complications can happen. This is a case of a 72 years old woman with cirrhosis secondary to Metabolic Associated Fatty Liver Disease (MAFLD), who presented recurrent hydrothorax after treating hepatocellular carcinoma (HCC) with radiofrequency ablation (RFA), and in which diaphragmatic perforation was subsequently diagnosed. We reviewed the differential diagnosis and management in a pleural effusion after a radiofrequency procedure. Although diaphragmatic perforation is an uncommon complication after RFA procedure, this case aims to help clinicians being aware of non-habitual complications.

Chemotherapy Exposure and outcomes of Chronic Lymphoid Leukemia Patients

Published on: 26th June, 2017

OCLC Number/Unique Identifier: 7317598103

This study describes chemotherapy exposure, healthcare utilization, overall survival (OS) and progression-free survival (PFS) among patients diagnosed with chronic lymphoid leukemia (CLL). Newly diagnosed CLL patients who received chemotherapy were selected from the Eindhoven Cancer Registry between 1998-2011, linked on a patient-level to the PHARMO Database Network including data on in- and out-patient drug dispensings, hospitalizations and clinical laboratory measurements. Chemotherapy was classified in regimens of use based on chemotherapy combinations. OS and PFS were determined after diagnosis and after chemotherapy. Healthcare utilization was assessed in the year before diagnosis and in the year after chemotherapy. In total, 125 CLL patients received chemotherapy: 52 patients (42%) started chemotherapy within 6 months and 73 patients (58%) started chemotherapy ≥6 months after diagnosis. Mean (±SD) age was 67(±10) years and 68% was male. About 50% had one treatment line and about 25% two lines of treatment. Chlorambucil was the most common type of first line chemotherapy. Prior diagnosis, 44% were hospitalized for any cause and 94% had at least one drug dispensing. After chemotherapy, this was 43% and 98%, respectively. One-year survival rate after diagnosis was 94%. Median PFS after first treatment line was 17 months for patients starting within 6 months and 27 months for patients starting ≥6 months after diagnosis. In conclusion, most CLL patients receiving chemotherapy were treated with chlorambucil. One-year after initial diagnosis, 94% were still alive. Median PFS after first line chemotherapy ranged from 17 to 27 months, depending on the timing of chemotherapy.

Cytokine Modulatory Effects of Sesamum Indicum Seeds Oil Ameliorate Mice with Experimental Autoimmune Encephalomyelitis

Published on: 30th October, 2017

OCLC Number/Unique Identifier: 7347013998

Background: Multiple sclerosis (MS) is an autoimmune disorder of the central nerve system (CNS), which affects the brain and spinal cord. Experimental autoimmune encephalomyelitis (EAE) is the most commonly applied experimental model for studying the MS. The aim of this study was to determine the effects of Sesamum indicum seeds oil on Experimental Autoimmune Encephalomyelitis (EAE) in mice. Methods: Sesame oil was administrated intraperitoneally three days before immunization. IFN-γ, IL-10, IL-17 and TGF-β levels and mRNA expression in supernatant of and within cultured mononuclear cells were assessed. Results: According to our results, sesame oil treated mice demonstrated significant disease severity reduction (P=0.01 and 0.001, respectively). Treated EAE mice also represented statistically significant delay in the onset of symptoms in comparison with control group. The average IFN-γ levels and mRNA of sesame oil treated EAE mice were less than untreated EAE group. IL-10 and TGF-β levels and mRNA did not differ significantly in sesame oil treated EAE mice in comparison to untreated EAE group. IL-17 levels and mRNA were also found to be decreased significantly in treated mice in comparison to untreated mice. Conclusions: Even thoughTH1 and TH17 cells through secretion of IFN-γ and IL-17, respectively, are involved in the pathogenesis of multiple sclerosis and EAE, but IL-10 has been shown to exhibit suppressive effects on these disorders. It can be concluded that sesame oil is able to induce TH2 and TH17-related immune responses and suppress TH1 type in EAE

Clinically and Radiological isolated syndrome (MS risk)

Published on: 28th July, 2018

OCLC Number/Unique Identifier: 7802610102

Background: The use of brain magnetic resonance imaging (MRI) for evaluation of neurological disorders has increased in the past two decades. This has led to an increased detection of incidental findings on brain MRI. The most common of these asymptomatic abnormalities are white matter lesions that are interpreted as demyelinating based on radiological criteria. However, in the absence of associated clinical symptoms suggestive of multiple sclerosis (MS), a definite diagnosis of MS can’t be made in patients with these incidental white matter lesions. These patients are diagnosed as CIS (clinically isolated syndrome) and RIS (radiologically isolated syndrome).Using the revised McDonald criteria now allows some patients who would have been diagnosed with CIS to be diagnosed as having MS before a second episode. Method: Sixty one patients, 40 females and 21 males, age ranged between 15 years and 58 years, were included in our study. In addition to a detailed medical and neurological history and examination, CSF and blood analysis for oligoclonal bands and IgG index were performed for all patients. Result: 41 patients had positive oligoclonal bands and IgG index. After clinical, MRI results and laboratory results 44 (72.1%) were diagnosed CIS and 17 (27.9%) were RIS. Conclusion: Diagnosis of MS not depend only on MRI finding but need clinical and laboratory work up including CSF and blood analysis for oligoclonal bands and IgG index to confirm diagnosis.

Lack of applicability of the Enterocyte Chloride ion secretion paradigm to the Pathology of Cystic Fibrosis

Published on: 23rd October, 2017

OCLC Number/Unique Identifier: 7900080180

This review examines of the concept of a defective chloride channel in epithelial cells being a major cause of cystic fibrotic pathophysiology. The central concept of the defective chloride ion channel paradigm is that faulty CFTR protein or failed delivery of CFTR protein to the mucosal membrane of epithelial cells is the basis of cystic fibrosis. Defective placement or function of CFTR prevents hydration of bronchial mucus that is normally caused by epithelial cells; these are capable through chloride ion secretion of transporting fluid to the mucosal surface. This concept relies heavily on a paradigm taken from intestinal physiology-namely that the intestinal epithelial cell secretes chloride ion and fluid and that this has conferred heterozygote selective advantage in carriers of the cystic fibrosis gene. This present review examines the evidence for that hypothesis and assembles evidence from past studies that it is the smooth muscle cell that is of greater relevance. This review does not aim to provide an overview of current research into cystic fibrosis. The intention is to provide an overview of past research that led to the concept of a failure of epithelial cells to hydrate bronchial mucus because of compromised CFTR function. It is important to present all past evidence for aspects of the chloride secretion hypothesis and its associated heterozygote advantage concept so that the important evidential milestones can be re-assessed.
