BACKGROUND: In Sri Lanka pertussis continues to circulate in the community and cases among adolescents and adults have been reported despite 95% coverage of the four dose pertussis vaccination during early childhood. Waning of immunity following natural infection or immunization may contribute to the persistent circulation. An adolescent booster dose is not included in the national immunization schedule of Sri Lanka, although this is routine practice in many countries. Therefore information on immunity to pertussis in the adolescent group is needed prior to considering vaccination schedule changes...

INTRODUCTION: Chronic Myeloid Leukaemia (CML) is characterized by derangement of various components of the haemostatic system resulting in thrombo-haemorrhagic complications. Although less common than other myeloproliferative neoplasms, derangement of various components of the haemostatic system is observed in CML. Haemostatic abnormalities have been described in relation to hyperleucostasis and drugs used to treat CML. However, the correlation between haemostatic derangements and phase of CML is unclear in the literature...

Studies on noninvasive motor cortex stimulation and motor learning demonstrated cortical excitability as a marker for a learning effect. Transcranial direct current stimulation (tDCS) is a non-invasive tool to modulate cortical excitability. It is as yet unknown how tDCS-induced excitability changes and perceptual learning in visual cortex correlate. Our study aimed to examine the influence of tDCS on visual perceptual learning in healthy humans. Additionally, we measured excitability in primary visual cortex (V1)...

Prognostic value of tumor volume for biochemical recurrence of prostate cancer remains controversial. We aimed to determine which tumor volume definition would optimally correlate with established prognostic factors and classify macroscopic tumor configuration. Radical prostatectomy specimens with follow-up to biochemical recurrence in the period between 2009 and 2012 were retrieved. Newly proposed categories of reconstructed three-dimensional macroscopic tumor configuration were nodular, medial prominence, subcapsular spreading, and miliary types...
