Results showed that ear diseases account for 6.1%, among them media otitis trended to increase with children age; deaf and dumb 0.2%, dull 0.1%. In the right ear and left ear the incidence of media otitis was similar. Hearing capacity was less sensitive if it has media otitis of both sides. In children, extern otitis was preponderant, while in adult the main problems were buzzed ear, hearing loss, drum membrane perforation, mainly in the centre, then in ¼ infero anterior and ¼ posterioinferior, chronic media otitis 97.75%, acute 2.25%.

A comparison study was carried out on 1,242 medical records of pharyngolaryngeal disease among pediatric inpatients with ages of 1 -15 in Hue Central Hospital and 2852 medical records of pharyngolaryngeal diseases among pediatric inpatients with the same ages in Aue hospital, West Germany. Results showed that the pharyngolaryngeal diseases were leading diseases among diseases of ear, nose and pharynx in both hospitals. The rate of these diseases treated by operation in Aue hospital was higher than this in Hue hospital. There was difference of the morbidity rate between age groups. The rate of treatment of infection disease and infections complication in Hue hospital was higher than this in Aue hospital. The Aue hospital considered in prophylactic operation, diagnosis and rehabitation better than Hue hospital. There was no death in Aue hospital while there were 6 deaths in Hue hospital.

The cross-sectional study was conducted on the ABO blood group of 833 medical students in Thai Nguyen. Using the standard blood serum which was produced by National Institute of Hematology and Blood Transfusion. The data of study was analyzed by biological statistic method. Results: The percentage of ABO blood group of Kinh, Tay, Nung, San Diu, Muong minority students was the same in order of common rule: O>B>A>AB; The blood group of H’mong minority students had the percentage of ABO blood group different from the rule, in following order B> O> A> AB.

Experimental results showed that the LD50 of extract of dry leaves of Barleria lupulina Lindl. Acanthaceae is 29.871.63 g/kg. The extract in the ratio of 5 to 1 had antibacterial activities on the strains of bacteria such as: S. aureus, P. aerugrinosa, E. coli and B. subtilis. In the ratio of 2 to 1 it had a great anti-inflammatory effect in the dose of 6g/kg of body weigh. This influence is reduced at 35% after 24 hours. It also provided the relief of pain in the dose of 15g/kg of body weight during the first-15 minutes. The effect gradually decreased after 20 minutes

Introduction: During a thyroidectomy, the neck is hyperextended. This position may inverse the tracheal axis to the endotracheal tube (ET), can cause damage to the vocal cords and tracheal wall. We propose a simple turn of the ET corresponding with the laryngo-tracheal axis to reduce of post-operative sore throat (PST) and hoarseness (H) in thyroidectomy patients. Methods: 122 patients undergoing general anesthesia were prospectively randomized divided into 4 groups. Gp1 (n=31): normal ET tube placement. Gp2 (n=30): normal ET tube rotated 180o following insertion. Gp3 (n=30): armoured tube. Gp4 (control, n=31): Normal ET tube in operations other than thyroidectomy, that require hyperextension. Cuff pressure (CP) and inspiratory peak pressure (IPP) were monitored during anesthesia. PST and H were evaluated by a VAS (0-10mm). Results: The 4 groups were similar in age, gender and intubation duration. IPP remained stable in all 4 groups. However, CP increased significantly in Gp1 and Gp4 after hyperextension. GP1 had the most PST and H (p<0.05). Tube rotation achieved the same results as the Armoured tube. Discussion: Rotating ET tube 180o reduced PST and H as much as intubation with a armoured tube. This rotation did not interfere with ventilation during anesthesia.
