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.

The regulatory effect of new synthetic thienopyrimidine derivatives on the growth and photosynthesis of wheat (Triticum aestivum L.) variety Svitlana in the vegetative phase was studied. The regulatory effect of new synthetic thienopyrimidine derivatives was compared with the regulatory effect of auxin IAA (1H-indol-3-yl)acetic acid) or synthetic plant growth regulators Methyur (sodium salt of 6-methyl-2-mercapto-4-hydroxypyrimidine) and Kamethur (potassium salt of 6-methyl-2-mercapto-4-hydroxypyrimidine). After 2 weeks, morphometric parameters (such as average length of shoots and roots (mm), average biomass of 10 plants (g)) and biochemical parameters (such as content of photosynthetic pigments (µg/ml)) of wheat plants grown from seeds treated with synthetic thienopyrimidine derivatives, or auxin IAA, or synthetic plant growth regulators Methyur and Kamethur at a concentration of 10-6M, were measured and compared with similar parameters of control wheat plants grown from seeds treated with distilled water. The regulatory effect of new synthetic thienopyrimidine derivatives on the morphometric and biochemical parameters of wheat plants was similar or higher compared to the regulatory effect of auxin IAA, or synthetic plant growth regulators Methyur and Kamethur. The relationship between the chemical structure of new synthetic thienopyrimidine derivatives and their regulatory effect on the growth and photosynthesis of wheat plants was revealed. The most biologically active thienopyrimidine derivatives are proposed to be used as new synthetic physiological analogues of auxins and cytokinins to improve growth and increase photosynthesis of wheat (Triticum aestivum L.)variety Svitlana in the vegetative phase.

In this study, we evaluated the assessed the hypoglycemiant, toxicogenetic and genotoxic effects of nanoencapsulate extracts of Bauhinia forficata Link. Phytochemical evaluations of extracts were carried out, as well as the evaluation using HPLC-MS and of antioxidant capacity in vitro. DM2 was induced in mice with streptozotocin and extracts were given orally for 28 days. That dried extract from infusion (ESIN) had a higher rate of bioactive compounds compared to the dried extract from decoction (ESDC), and higher antioxidant capacity. Glucose levels decreased from 77.26% to 57.79% and 45.15% after supplementation with ESIN (200 and 600 mg/kg/day) and ESDC (600 mg/kg/day), respectively, when compared to the diabetic group treated with metformin (600 mg/kg/day) (21.53%), with an improvement in the glycemic response e recovery of pancreatic β cells. Thus, our study has shown that these extracts exhibit hypoglycemiant activity, with a beneficial effect superior to metformin, as a result they could be considered as potential therapeutic agents for application in pharmaceutical formulations in the treatment of DM2.
Vitamin D has immunomodulatory and antifibrotic properties, and therefore used for treatment of many of chronic liver disease [1]. Although there are many reports on the relationship between serum 25-hydroxyvitamin D3 levels and chronic liver diseases, but the relationship between hepatitis B virus e antigen (HBeAg) and vitamin D level is still unclear.
The modification and prevention of vitamin D deficiency needs an accurate illustration of the current position in each region. Vitamin D level in patients with HBV is relatively an important issue, which has been studied in many researches. As different papers published in national and international journals.
Steady-state VEPs, have been used to estimate visual acuity since the 1970s and allow responses to a range of stimulus sizes to be collected rapidly- with particular utility in infants. However, the assessment of children with cortical visual impairment is a bigger challenge that lead to the development of the Step VEP. Its initial evaluation revealed that accuracy and precision were poorer for pediatric patients than for optically degraded normal adults and that it was not necessarily successful in every child. Statistical models generated the equations: VAO = 0.56 VAStep (r2 = 0.75, F = 60.93, p = 0.000) and VAPL = 0.45 VAStep (r2 = 0.82, F = 156.85, p = 0.000), supported by a recent a systematic review of VA comparisons showing that recognition VA (optotypes) agrees more closely than discrimination VA (PL) with VEP VA. In combination, Step VEPS and subjective tests allowed complete assessment in 96% of patients, with incomplete Step VEPS much more likely to be partially successful than not, and more likely to be partially successful than incomplete subjective tests. This supports the rationale that Step VEPs maintain attention by limiting the time spent stimulating away from an individual’s threshold of spatial resolution. For the small number of patients in whom VA cannot be estimated, alternative stimuli and methods of presentation are proposed.

Introduction: Obesity may cause progressive chronic kidney disease. Weight loss in the postoperative follow-up of bariatric surgery may improve renal function in these patients. Thus, the purpose of this study was to give insight on the subject using a sensible biomarker.
Methods: This cross sectional study was performed in the Obesity Department from Campina Grande – Paraiba, Brazil. It was randomly enrolled 23 postoperative patients (7 bypass and 16 sleeve), with at least two years of follow-up, from the outpatient Department and 29 (18 bypass and 11 sleeve) in the preoperative period for bariatric surgery. They were homogeneously from both genders with ages ranging from 25 to 57 years. Serum levels of creatinine and cystatin C were measured, and the glomerular filtration rate (GFR) was estimated using the CKD Epi (chronic kidney disease epidemiology collaboration) cystatin-creatinine equation. The investigation was approved by the Ethics Committee.
Results: The mean body mass index (BMI) of the preoperative group was significantly greater than the postoperative group (p ≤ 0.0001). The mean serum levels of C cystatin was significantly greater in the postoperative group as compared to preoperative (p= 0.0197). However, there was no mean difference between creatinine serum concentrations comparing the two groups (p = 0.3252). The mean glomerular renal function rates of the groups were similar (p = 0.1240).
Conclusion: There is no definitive evidence for supporting the hypothesis that there is improvement in the kidney renal function after bariatric surgery in obese patients. Prospective cohorts are necessary to enlighten the answer for this important question.
Background: In health care systems nursing care documentation is a vital and powerful tool that ensures continuity of care and communication between health personnel for better patient outcomes. Knowledge, attitude and practice of nurses’ towards nursing care documentation affect the quality and coordination of patients’ care. Hence, this study aimed to assess knowledge, attitude, practice and associated factors towards nursing care documentation among nurses in West Gojjam Zone public hospitals, Amhara Ethiopia.
Method: Institutional based cross sectional study was conducted among 246 nurses in West Gojjam Zone public hospitals from February to March 8, 2018. The study participants were selected by simple random sampling technique. Data were collected by using pre-tested and validated self-administered structured questionnaire with internal reliability of Cronbach’s Alpha values 0.912, 0.784 and 0.713 for knowledge, attitude and practice questions respectively. Epi data version 3.1 and SPSS version 20 was used for data entry and analysis respectively. Descriptive statistics and binary logistic regression model were used.
Result: The overall response rate was 97.56%. Among 240 respondents 54.6% of them had good knowledge, 50% of study participants had favorable attitude and 47.5% of study participants had good nursing care documentation practice. Sex and monthly salary were found to be statistically significant with knowledge of nurses. Work setting, work experiences and knowledge of nurses had significant association with nurses’ attitude towards nursing care documentation. Availability of operational standards, knowledge and attitude of nurses had significant association with nursing care documentation practice.
Conclusions and Recommendation: Results of this study showed that knowledge, attitude and practice of West Gojjam zone public hospital nurses on nursing care documentation were poor. Therefore; in order to solve this problem each hospital should recruit nurses until hospitals are saturated enough. It is recommended to avail nursing care documentation standards/guidelines in each hospital and to give training about it and also it is recommended to conduct multisite studies especially qualitative type to increase its quality.
Typhoid fever is a systemic infection caused by Salmonella enterica serotype typhi. It is of major concern in tropical regions of the world. Highest episodes of typhoid fever occur in Asia i.e.93%. Early diagnosis of the disease is mandatory to lower the mortality rate associated with it as well as to prevent the emergence of antimicrobial drug resistance by Salmonella typhi. Research work was conducted in Immunology Department of the Children’s Hospital, Lahore for the period of one year including a total of 60 patients suspected of having typhoid fever. Serum samples of these patients were tested for typhidot IgG and IgM antibodies as well as for the antibodies against TO and TH antigens using Widal test. Of the total 60 patients, 10 (16.7%) were positive for both typhidot IgG and IgM, 16 (26.7%) were positive for typhidot IgM, 3 (5%) were Positive for typhidot IgG and 31 (51.66%) were negative for both typhidot IgG and IgM. Reading the results of Widal test, 8 (13.33%) were positive for Widal TO and TH antigens, 3 (5%) were positive for Widal TO antigen, 19 (31.7%) were positive for Widal TH antigen and 30 (50%) were negative for Widal TO and TH antigens. IgM is positive at the early stage of acute typhoid fever, IgM along with IgG positive means the middle stage of acute illness. The detection of only IgG cannot discriminate between acute and convalescent phases as it can stay in the serum for at least 2 years or more. The typhidot test is much helpful for the rapid diagnosis of typhoid fever as compared to Widal test which is still being used in some set ups in poor countries, although has become mostly obsolete. By testing the rise of IgM and IgG antibodies against Salmonella typhi, we can detect the infection at early and late stages, respectively

Introduction: Pulmonary hypertension (PH) is prevalent in hemodialysis (HD). In the general population, more women than men have PH due to left ventricular (LV) disease with preserved ejection fraction (EF). Little is known about the gender-specific prevalence of PH and associated LV abnormalities in patients with end stage renal disease (ESRD) on HD. Our aim was to evaluate gender differences and LV structural and functional changes in PH among ESRD patients on HD.
Methods: Ninety-four patients (ages 23-77 years) underwent echocardiography after HD. Patients were divided based on estimated pulmonary artery systolic pressure (PASP) (Group A PASP < 40 mm Hg, Group B PASP ≥ 40 mm Hg). LV measurements included LV mass, LV internal dimensions, and LV ejection fraction (EF). LV diastolic function (LVDF) was assessed from mitral inflow deceleration time (DT) and E/A ratio.
Results: Fifty-five patients (59%) had PH, including 32 of 49 men (65%) and 23 of 45 women (51%). LVEF was lower in Group B (46.4 ± 17.6 vs. 62.4 ± 14.4%, p < 0.001). Men with PH had higher LVIDd, cm (5.52 ± 0.89 vs 4.78 ± 0.75, p < 0.001), LVIDs, cm (3.75 ± 0.94 vs 3.14 ± 0.91, p = 0.03) LV mass, g (236 ± 74vs 189 ± 56, p = 0.02) and lower LVEF (40.0 ± 16.7 vs 52.0 ± 15.6, p = 0.008) than women.
Conclusion: Patients on HD have a high prevalence of PH. PH was not associated with clear LV structural changes. There was a depression in LV systolic function without changes in LVDF. PH patients were more often men with hypertrophied LV with depressed LV systolic function.
Background: Cochlear implants (CI) are nowadays a widely accepted treatment for sensorineural hearing loss SNHL.
Aim: This study aimed to describe the epidemiological characteristics and the surgical approach and to evaluate the outcomes of our experience in cochlear implantation.
Setting: Department of Otolaryngology-Head and Neck Surgery of University Hospital Mohammed VI Marrakech Morocco.
Methods: A retrospective chart review was conducted on 113 patients with severe to profound hearing loss who underwent a cochlear implantation between 2007-2018.
Results: There were 65 females and 48 males with severe to profound bilateral deafness, of whom 103 had prelingual deafness. The mean age of pediatric cochlear implantation was 5.25 years. Implantation was unilateral in all patients. The procedure was followed by regular adjustments and speech therapy. The evaluation was carried out by the same team each month during the first 6 months, then every 6 months. The average duration of follow-up was 37.54 months. All patients benefited from their implants with inter individual variability.
The good results were correlated with early implantation, significant parental investment and a steady follow-up of speech therapy.
Conclusion: Cochlear implantation has revolutionized the management of severe to profound deafness. It is a safe and effective technique when it is aimed at correctly selected populations.
