We present a case of an 18-year-old boy with neurofibromatosis type 1 and hypertrophic cardiomyopathy with systolic anteward movement of the anterior leaflet of the mitral valve. Gradient in the left ventricular outflow was 85 mm Hg secondary to subvalvular aortic stenosis with left ventricular diastolic dysfunction. The possibility of a coincidence, or a causal relationship of these 2 conditio...
In China, the epidemiological and socioeconomic status of the migrant population suggests that the vulnerable population should be prioritized for tuberculosis (TB) control. A face-to-face interview using a structured questionnaire was performed on a total of 314 smear-positive pulmonary TB patients among the migrant population of 12 randomly selected counties in Shandong Province, China. From ...
BACKGROUND The overall incidence of tuberculosis (TB) in Western Europe has been declining since the 19th Century. However, immigrant sub-groups from high-prevalence countries are slowing down this trend. The aim of this study was to describe how immigration influences TB transmission in Germany. For that we prospectively investigated the dynamics of TB transmission between TB high-prevalence i...
Pulmonary lymphangioleiomyomatosis (LAM) is a rare disorder presenting with remarkable features like recurrent pneumothorax or chylothorax, usually in young women. We report a case of sporadic LAM who presented with nothing but recent onset exertional dyspnoea and it was this unobtrusive presentation that led to delay in diagnosis.
The incidence of tuberculosis (TB) and its risk factors in China remains unclear. This study examined TB incidence and relative risk factors in rural areas of China. Participants (n = 177,529) were recruited in Xiangtan County (in the central area of China) and in Danyang County (in the eastern area of China) in 2009 and a followed-up study was conducted for one year. The incidence density of p...
A review of the pathology of human pulmonary TB cases at different stages of evolution in the pre-antibiotic era suggests that neutrophils play an instrumental role in the progression toward active TB. This progression is determined by the type of lesion generated. Thus, exudative lesions, in which neutrophils are the major cell type, are both triggered by and induce local high bacillary load, ...
BACKGROUND There is paucity of data on seasonal variation in pulmonary tuberculosis (TB) in developing countries contrary to recognized seasonality in the TB notification in western societies. This study examined the seasonal pattern in TB diagnosis among migrant workers from developing countries entering Kuwait. METHODS Monthly aggregates of TB diagnosis results for consecutive migrants test...
The diagnosis of tuberculosis remains challenging in individuals with difficulty in providing good quality sputum samples such as children. Host biosignatures of inflammatory markers may be valuable in such cases, especially if they are based on more easily obtainable samples such as saliva. To explore the potential of saliva as an alternative sample in tuberculosis diagnostic/biomarker investi...
BACKGROUND Although China has paid more attention on the prevention and control of tuberculosis (TB) in schools, several unsolved questions in this field still threaten the progress of TB control. Therefore, there is an urgent need to develop a systematic and practical strategy for Chinese school TB prevention and control system. In this study, we aimed to assess the feasibility of a combined s...
LTHOUGH THE PULMONARY REACTION to all dusts is characterized in the early phase by a stroma of reticulin fibers, and this stroma remains essentially unchanged in reactions to so-called “inert” dusts, in the case of quartz dust, the reticutin is replaced by collagen after a latent period. Many papers have been written attempting to explain why quartz dust is so different as to cause a collagenou...
