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.

Object: 2875 married woman in child bearing age (15 to 49) at 15 commune/ward in 7 suburban distric of Ha Tay province. The result show that: Reproductive tract infections rate is 64,24%. Incidence of countryside woman is higher than city woman. At the age group of 25-39 has the highest incidence. Types of pathogenic organism is multiform, leading is vagina bacterium with exiting of bacillus G (1), cocus G (+) particular is Gardnerella vaginalis. Infected Candida rate is quite high, infected Trichomomas is in low level. Antibiotic is resisted in various level.

From Aug 2001 to July 2002 at St Paul Hospital in Hanoi, 300 fecal samples collected from 300 diarrhoea children aged from 3 months to 5 years old were studied. Results showed that in 51,9% of cases, rotavirus was the leading cause, Escherichia coli was the second, among which addhesive strains and invasive strains of coli were the most common. In first time, toxic gene was detected in the group of intestinal hemorrhagic Escherichia coli. Shigella and Campillobacter were still the common pathologic causes of pediatric diarrhoae

1552 strains (42.09%) of bacterium were isolated from 3687 specimens (pus, blood, throat swab, sputum, bronco-tracheal aspirate, pleural fluid, bile fluid, abscess and other) of patients at Central Military Hospital 108 (1999-2000). 43.44% of these strains were positive gram cocci, including S. aureus (16.63%), S.epidermidis (18.49%), and 53.34% were negative gram cocci, including E. coli (18.6%), P. aeruginosa (16.12%), Enterobacter (8.31%), Proteus spp. (7.34%).

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

Background: Non-small cell lung cancer is the most common type of lung cancer. It usually grows and spreads more slowly than small cell lung cancer. Objective: To describe clinical characteristics and the TNM staging of non-small cell lung cancer. Subjects and method: It was a prospective study on clinical characteristics and the TNM staging of 53 patients with non-small cell lung cancer in Bach Mai Hospital from January 2005 to June 2005. Results and conclusions: The most common age was over 40, accounting for 92.5%, male/female (2.5/1). 64.2% of cases with smoking history (97.1% for men and 2.9% for women). 79.4% of patients had smoked over 20 years. The concordance of diagnosis between the previous hospitals and Bach Mai hospital was 34.6%. The most common clinical symptoms at the time of diagnosis were chest pain, prolonged cough, haemoptysis, weight lost and pleural effusion syndrome. Basing on the 1997 International Staging System of Non-Small Cell Lung Cancer, we have found that T4 in 64.2%, N(+) 64.2% and metastasis in 32.1%. IIIB and IV stage in 75.5%, patients with IA to IIIA stages being able to be operated was 24.5% of cases. 92.5% of patients were over 40 years old; male/female: 2.5/1. 79.4 of patients had smoked cigarette over 20 years.
