The study involved 197 patients at Clinical Immunology - Allergy Department of Bach Mai Hospital. These patients were diagnosed with asthma based on diagnostic criteria of the American Thoracic Association. Method: Clinical examination. Time of disease onset and factors that related to the arise of first breath difficulty. Date was processed by statistic method. The results showed that asthma could arise at any age. The prevalence is highest (39.59%) in children and teens (0-20 years of old) and lowest (4.06%) in group of 60 years of old or more. Among causal factors of asthma, respiratory inflammations such as bronchitis, pneumonia, tonsillitis and allergic rhinitis were most common (67.5%).

The manifestations of pediatric gastroesohageal reflux (GER) are varied and complex. Extra-oesophageal symptoms, including GER-related respiratory diseases, ear, nose and throat diseases, oral diseases and neuropsychiatric symptoms, are thought to be major manifestations of pediatric GER, but the causal relationship between GER and these extra-oesophageal symptoms is still unclear. Therefore, we describe the progress of research on the relationship between GER and asthma, chronic cough, laryngitis, pharyngitis, laryngeal papilloma, sinusitis, otitis media, dental erosion, apparent life-threatening event, and the crying baby syndrome in this review. It provides new strategies for the diagnosis and treatment of GER-related diseases in children.

Cancer comprises of 200 separated diseases with some common characteristics: Unregular and unlimited proliferation of cells, it invades through the natural frontiers and spreads far on the whole of the body, leading to the death. International Anticancer Association defines the tumor as some neoplastic tissues growing excessively over the normal need and the range of control of the body. The progress of cancer is a multicause pathology, it developes in long duration, having 3 basic phases: onset, progress and advance. In advanced phase the disease trends to spread largely, destrying the host leading to the death

From January 1999 to December 2003, 60 adult patients with intussusception were treated at Cho Ray Hospital, Hochiminh City. The results showed that: among them, evident etiology was recognized in 86.7% cases, including 63.5% intestinal tumors. Of cases of small intestine tumors, there were 12 benign cases (85.7%), and percentage of colonic tumors were malignant 76.9%. The treatment depends on etiology and site of intussusception. 3 surgical procedures were disinvagination, intestinal resection and right/left hemicolectomy. Surgical successful rate was 93.3%. There was no death

Literatures have demonstrated the association between oral diseases and systemic diseases. For example, periodontitis is associated with coronary heart disease, diabetes, preterm low birth weight, and gastritis. Therefore, more relevant research on the relationship between oral diseases and systemic diseases should be carried out.
