Abstract Background Ruptured oesophageal varices (OVs) is a major cause of mortality in Portal hypertension (PHT) patients, It has been a great issue of interest and research to screen and early detect OVs via oesophageal varices non-invasive methods. Objective The aim of this study was to assess the reliability of measuring plasma von willibrand factor antigen (VWF-Ag) for prediction of the occurrence of oesophageal varices in patients with portal hypertension. Subjects & Methods This was a prospective cross-sectional study, done on 47 children with portal hypertension. The children were recruited from Pediatrics Hepatology clinic, Ain Shams University. Patient’s data was collected including age, sex, etiology and duration of PHT, along with medical treatment. Also an upper GIT endoscope, abdominal doppler ultrasound, and laboratory tests including measuring of plasma VWF-Ag were done to each patient. Then the children were divided based on their endoscopic findings into two groups; variceal group which included 37 patients, and a nonvariceal group which included 10 patients Results: The results of our study revealed an elevated plasma VWF-Ag in patients with oesophageal varices, whilst normal levels of plasma VWF-Ag in the non-variceal patients. In addition, there was a direct positive correlation between increased plasma VWF-Ag and the degree of oesophageal varices. Conclusion Since the plasma VWF-Ag level correlates with the presence and degree of OVs, it can be used as a noninvasive indicator of the presence and degree of OVs, However, further studies using larger sample might be needed to support this.

Abstract Background Ruptured esophageal varices (EVs) are a leading cause of death in Portal hypertension (PHT), it has been a big concern of research to screen EVs through non-invasive approaches. This study aimed to evaluate the role of plasma von Willebrand factor antigen (VWF-Ag) assay for early detection of EVs in patients with portal hypertension. This was a cross-sectional study, done on 47 portal hypertensive children and adolescents who were collected from the Pediatrics Hepatology Clinic, Children Hospital, Ain Shams University. All patients were subjected to comprehensive history taking, thorough clinical examination, routine investigations, abdominal ultrasound, upper GI endoscopy, and measurement of plasma VWF-Ag level. The patients were divided based on their endoscopic findings into two groups; a varices group which included 37 patients, and a non-varices group which included 10 patients. Results VWF-Ag rise significantly in patients with EVs, revealing a direct positive association with the degree of EVs. Conclusion The plasma VWF-Ag can be applied as a non-invasive evidence of the presence and grading of EVs.

Backgrounds: VonWillebrand disease (VWD) is reportedly the most common inherited bleeding disorder and can also arise as an acquired syndrome (AVWS). These disorders arise due to defects and/or deficiency of the plasma protein von Willebrand factor (VWF)..High plasma vWF concentrations have been reported in patients with various types of cancer, such as prostatic cancer.Metastasization may be associated with activation of haemostatic processes resulting in increased levels of circulating factor VIII-related antigen (FVIIIRAg) (von Willebrand factor antigen). Objective: To evaluate the status of VWF AginSudanese patients with Prostate Cancer attending RICK Methodology: This is a cross-sectional study carried out in Khartoum state at Khartoum oncology (RICK) hospital, during the period from April to June 2018, 45 samples were collected from patients with non-metastatic CA prostate, their ages ranged between 51 to 82 years. The vWF level was measured using Enzyme-linked immunosorbent assay (ELISA). Data were analyzed by the statistical package for social science (SPSS).   Results: Serology for vWF antigen was done for 45 cases of prostate cancer. According to the age, 2(8%) of patients with age 51-66 had a high concentration of VWF while 24(92%) had normal vWF antigen concentration; of those with age 67-82 years, 4(21%) had high vWF antigen and 15(79%) had normal antigen. Conclusion: The study revealedthat more than 80% of Sudanese patients withnon-metastatic prostate cancer have anormal concentration of VWF. Keywords: vWF, Prostate cancer, Age, ELISA

Introduction: Acute Upper Gastrointestinal (UGI) bleed is a common potentially life threatening emergency. The aetiological profile of bleed and prognosis varies according to geographical region and availability of endoscopic facilities. Aim: To determine the clinical and endoscopic profile of UGI bleed, risk factors and prognosis in the patients. Materials and Methods: This was a cross-sectional study conducted over a period of 12 months at a tertiary care centre in Southern India. Patients admitted with history of hematemesis and melena, satisfying the inclusion criteria was taken consecutively. Clinical and endoscopic profile were noted and followed-up for six weeks. Statistical analysis was performed using chi-square test for qualitative variables and independent t-test for quantitative variables. Significance level was fixed as p-value of <0.05. Results: A total of 138 patients were studied in this period. The male to female ratio in the study was 3.5:1. The mean age was 53.5±13.17 years. The most common clinical presentation was hematemesis in 57 patients (41.3%) followed by haematemesis and melena in 46 patients (33.3%). The most common cause on endoscopy was portal hypertension-related oesophageal and gastric varices (51.4%) followed by antral gastritis (15.2%). The cause of UGI bleeding could not be identified in 5.1% in which the endoscopy was normal. Haemogram, platelet count and serum albumin were significantly lower in variceal bleed group, compared to non-variceal group. Eleven patients succumbed to death secondary to UGI bleed. Conclusion: The most common causes of UGI bleed are portal hypertension related gastric and oesophageal varices. The in-hospital mortality in the study was 7.9%.

Background: Streptococcus pneumoniae is recognized as one of the main pathogens inducing several invasive and non-invasive infections in children. Objective: The present study aimed to evaluate the serotype distribution of S. pneumoniae in six–month–old carriers. Methods: This study encompassed 600 six-month-old healthy infants whose pharyngeal swap samples were collected and then cultured to isolate S. pneumoniae. Twenty- five different serotypes were defined on positive culture samples by multiplex PCR. Results: In this study, 13 cases (2.2%) were positive S. pneumonia. The most common isolated serotypes of S. pneumoniae were serotypes 23F (n = 6, 1%) and 3 (n = 3, 0.5%), respectively. Notably, the most frequent serotype in formula-fed infants (n = 300) was Serotype 23F (n = 5, 1.7%); however, Serotype 3 (n = 3, 1%) was the most frequent one in breastfed participants (n = 300). According to the findings, the overall coverage of PCV10, PCV13, and PPSV23 on the S. pneumoniae serotypes at the age of six months was 50%, 73%, and 85%, respectively. Conclusions: At this age, the type of feeding could not significantly affect the frequency rate of S. pneumoniae colonization, while the serotype distributions in the two breastfed and formula-fed groups were different.

Abstract Monitoring metabolic adaptation to type 1 diabetes mellitus in children is challenging. Analysis of volatile organic compounds (VOCs) in exhaled breath is non-invasive and appears as a promising tool. However, data on breath VOC profiles in pediatric patients are limited. We conducted a cross-sectional study and applied quantitative analysis of exhaled VOCs in children suffering from type 1 diabetes mellitus (T1DM) (n = 53) and healthy controls (n = 60). Both groups were matched for sex and age. For breath gas analysis, a very sensitive direct mass spectrometric technique (PTR-TOF) was applied. The duration of disease, the mode of insulin application (continuous subcutaneous insulin infusion vs. multiple daily insulin injection) and long-term metabolic control were considered as classifiers in patients. The concentration of exhaled VOCs differed between T1DM patients and healthy children. In particular, T1DM patients exhaled significantly higher amounts of ethanol, isopropanol, dimethylsulfid, isoprene and pentanal compared to healthy controls (171, 1223, 19.6, 112 and 13.5 ppbV vs. 82.4, 784, 11.3, 49.6, and 5.30 ppbV). The most remarkable differences in concentrations were found in patients with poor metabolic control, i.e. those with a mean HbA1c above 8%. In conclusion, non-invasive breath testing may support the discovery of basic metabolic mechanisms and adaptation early in the progress of T1DM.
