Trèlat's beads as oral manifestations in patients with HIV/TB

Tuberculosis (TB) is a contagious infectious disease caused by Mycobacterium tuberculosis (Koch's bacillus). Co-infection with human immunodeficiency virus (HIV) and TB has reached a significant importance as a public health problem and this association has been recognized as the most significant event that changed "the balance between man and Koch's bacillus" in the last century, and has a large contribution to the risk for disease spreading. Tuberculosis has two main standard categories of clinical manifestations: primary and secondary. Primary TB is responsible for the initial infection with lungs being the involved organ. Oral lesions are observed as a secondary TB clinical manifestation with most frequent sites being hard and soft palate, tongue, lips, gums, tonsils, and salivary glands. A case of classical TB lesions in the oral cavity is reported, and the importance of a correct diagnosis through careful history taking is emphasized. Treatment selection needs to be done assertively, with great determination and building a link between patient and treatment protocol, in order to promote patient's adherence.

ROC curves of obesity indicators have a predictive value for children hypertension aged 7-17 years

Objective: The aim of the study is to examine the distribution of integrated covariate and its association with blood pressure (BP) among children in Anhui province, China, and assess the predictive value of integrated covariate to children hypertension. Methods: A total of 2,828 subjects (1,588 male and 1,240 female) aged 7-17 years participated in this study. Height, weight, waistline, hipline and BP of all subjects were measured, obesity and overweight were defined by an international standard, specifying the measurement, the reference population, and the age and sex specific cut off points. High BP status was defined as systolic blood pressure (SBP) and/or diastolic blood pressure (DBP) > 95th percentile for age and gender. Results: Our results revealed that the prevalence of children hypertension was 11.03%, the SBP and DBP of obesity group were significantly higher than that of normal group. Anthropometric obesity indices such as body mass index (BMI) were positively correlated with SBP and DBP. Integrated covariate had a better performance than the single covariate in the receiver-operating characteristic (ROC) curve, the cut-off value; the sensitivity and the specificity of the integrated covariate were 0.112, 0.577, 0.683, respectively. Conclusion: Integrated covariate is a simple and effective anthropometric index to identify childhood hypertension.
