Purple urine bag syndrome (PUBS) is a rare and strikingly prominent phenomenon associated with recurrent urinary tract infection caused by bacteria with indoxyl phosphatase and sulfatase activity. Recognising this entity is important to avoid undue investigations, misdiagnosis and erroneous treatment. We report an interesting case of PUBS in a 76-year-old female patient who developed PUBS secondary to UTI caused by ESBL Proteus mirabilis. Also, to the best of our information this is the first case of PUBS reported from this region.

Statement of Problem: Multiple studies have been conducted to evaluate the effect of aging on the mechanical properties of computerized-aided design and computerized-aided manufacturing (CAD/CAM)-based zirconia; however, there is a scarcity of literature discussing the effect of aging on change in translucency and surface roughness for both Translucent zirconia and lithium disilicate. Aim of the study: To evaluate the surface roughness and translucency of zirconia and lithium disilicate veneers aged by artificial aging.

This study aimed to evaluate oral pathological processes and/or dental anomalies associated with unerupted permanent second molar in cone beam computed tomography images of adolescents and adults. This is a retrospective cross-sectional study in which unerupted second permanent molars were analyzed using tomographic images obtained from 16 brazilian patients. Thirteen of whom had second permanent molars with unilateral impaction and 3 bilaterally, totalling 19 tomographic images.

O Esse trabalho tem como principal objetivo a análise dos dados epidemiológicos acerca da tuberculose no Brasil, além disso, tem como objetivo secundário a demonstração destes dados de forma analítica. Trata-se de um estudo epidemiológico quantitativo, utilizando dados secundários. Com isso, pôde-se considerar que os fatores biopsicossociais têm impacto direto nos indicadores de tuberculose no país, sendo inversamente proporcional aos índices de desenvolvimento da população.

O presente estudo tem como objetivo principal a demonstração dos dados epidemiológicos acerca dos casos confirmados de infecção por HIV. Como objetivo secundário, há a proposta de auxiliar o entendimento acerca das políticas públicas de mitigação da transmissão. Trata-se de um estudo quantitativo acerca dos casos de infecção pelo HIV, utilizando como referência o banco de dados do Ministério da Saúde do Brasil, o DATASUS, na plataforma TABNET.

Objectives: A Non-Dimensional Physiological Index (NDPI) is a dimensionless parameter that can help characterize an abnormal state associated with a particular physiological system.

Background: This study was conducted to compare Vitamin D Serum Levels in Patients with Oral Lichen Planus and Healthy Subjects. Material and methods: There were 20 subjectsincluded in the study, diagnosed with Oral Lichen Planus and 20 subjects without the condition. Vitamin D serum levels was measured in both Oral Lichen Planus subjects and healthy controls after collecting 5 mL of blood from each group and analysing it with a vitamin D total (25-hydroxy vitamin D) kit using the electrochemiluminescence technique. Patient consent form were taken and recorded.

This article deals with the concept of knowledge engineering, knowledge systems, the need for a knowledge engineering methodology, the common KADS suite of models and roles of knowledge-engineering projects. It has been pin-pointed that knowledge engineering provides the methods to obtain a thorough understanding of the structures and processes used by knowledge workers- even where much of their knowledge is tacit-leading to a better integration of information technology in support of knowledge work.

Potato is an important grain crop for millions of poor farmers and consumer in the semi-arid region of West Africa. It is one the four most important cereals (rice, maize, sorghum and millet) grown in tropical in tropical semi-arid regions of the world primarily in Africa and Asia. Potato is well adapted to production system characterized by low rainfall (200-600mm), low soil fertility and high temperature. It is generally used as a temporary summer pasture crop or in some areas as a food crop.

Introduction: Congenital lobar emphysema (CLE) is a rare disease, of still unknown etiology, with an incidence of 1:20-30 thousand births. Its prevalence by sex remains under discussion. It is characterized by progressive lobar hyperinflation, due to air trapping of a collapsed airway, resulting in distension of the lobe and causing a mass effect that compresses the other lobes and diverts the mediastinum. Diagnosis is made through imaging tests, and treatment is usually surgical.
