From December 2000 to March 2003, at Huu Nghi Hospital, 85 patients with tracheal intubation were studied. There was no statistically statistic significances between 2 groups (of success and of failure) concerning the age, predicted body mass, the duration of mechanical ventilation. The causes of respiratory deficiencies needing mechanical ventilation were: infections, cerebral infarctus, cerebral hemorrhagy, acute left heart failure, acute myocardiac infarctus, diabetes. CROP diagnostic value of weaning from mechanical vetilation was higher in success group than in failure group. Threshold value of CROP index  13 (ml/breathing rythm/minute) had got a sensitivity of 0.65, specificity 0.89, predicted positive value 0.84, negative 0.74, under curb surface ROC = 0.875.

66 flaps including 6 controlled, were divided into two models, each includes 30 flaps and each model was divided into 5 groups, evaluated after 4, 8, 12, 16 and 20 days after implantation. From the random implantation of a isolated pedicle of artery or vena in an abdomen skin flap, new blood vessels occurred and connected with the existent system of vessels in the flap. After 20 days, new vascularity was established in both models, as the same in the control group. Blood supply was considered appropriate and the flap could be moved safely along the newly implanted pedicle

40 patients with bronchial asthma in Bach Mai hospital from 6/1998 to 5/1999 and 31 healthy people without allergy. Methods: finding the allergic history and skin test. The results: 52.5% of patients had his own allergic history; 42.5% of patients had a family history; 37.3% of patients had positive skin tests to foreign bodies of house dust mite; 32.5% of patients had allergic antibody against foreign bodies of house dust mite was more 30%. Among methods of specific diagnosis of allergy, there was a close relation between skin test and reaction of decomposition of mastocyte.

Contribution to the establishment and /or improvement of study on some criteria of cytologic diagnosis 5 major lung carcinomas. 50 cases of lung cancer including 14 squamous carcinomas, 18 adenocarcinomas, 8 large cell carcinomas, 8 small cell carcinomas and 2 adeno-squamous carcinomas were diagnosed cytologically and confirmed by histological confrontation. Criteria of cytologic diagnosis were presented and discussed.

In bethesda, the first requirement is correct and enough collection of sample which helps evaluating correctly. In the table of the detailed described diagnosis including 6 major classes, the a typical squamous cells with undetermined significant (ASCUS) followed the class of reaction lesion and is the first position of the class of the early cancer in screening the cervical cells in recent years. Therefore, ASCUS is considered as a lesion in the medium level, higher than the repaired lesion such as reserve cell hyperplasia or squamous cell teroplasia at the lower level of the squamous intrathelial lesion including types of low and high toxicity.

26,492 women from various regions, including 207 communes (203 from the North and the Middle of Vietnam, 4 from Can Tho province) and 3 hospitals (2 in Ha noi and 1 in Can Tho) have been examined (from 1990 to 1996) in order to detect early lessions of cervix cancer by cytological screening. The results are summarized respectively as follows: 1. Communes (on the whole): SIL all types (3.36%) among them LSIL (2.49%) and HSIL (0.87%); invasive carcinomas (0.029%). In Can Tho province (corresponding rates): 3.69% with LSIL (2.71%), HI|SIL (0.98%) and invasive carcinomas (0.06%). 2. Hospitals. Ha noi hospitals: SIL all types (5.62%) with HSIL (2.28%) and invasive carcinomas (0.05%). Can Tho hospital (respectively): 4.57%, 2.38% and 2.75%. The diffirences betwween the morbidity and the ASR (100,000 people) in the North and in the South are discussed.

There were 89 patients, no death in an outbreak of cholera in Dong Thap province, which happened on January 1st 1999 and lasted for 2 months. The morbidity was 5,61/100.000 inhabitants with all ages; the disease occurred at districts, towns along the Cuu Long river. Local authorities had conducted measures for cholera prevention and control.

The capillaroscopy is a method to early diagnose the symptoms of capillary spasm in the vibration. Beside of usual microscope M- 70 A of Soviet Union, any microscope can be used to illuminate and take the photograph of the capillary of finger transnail skin fold.

The study was conducted on 82 simple goiter patients and 91 Basedow patients after at least one year using iodized salt daily. The results showed that the uptake of radioactive iodine (RAIU) by the thyroid gland of simple goiter and Basedow patients decreased after 2 and 24 hours taking an oral dose of radioactive iodine. Especially, the decrease was 40-50% in simple goiter patients. The concentration of T3, T4, TSH in the sera was as following: in the simple goiter patients, the concentrations of T3 and TSH were slightly decreased, and the T4 serum concentration was increased. However, all the values were still within the normal range of euthyroidism. In Basedow patients, the concentrations of T3, T4, and TSH have not changed.

Diagnostic curettage has for many years been the method of choice to diagnose endometrial cancer in women with postmenopausal bleeding. In fact, approximately only 10% in this group of women will be diagnosed with endometrial cancer. This study used endometrial thickness as measured by endovaginal ultrasonography as an indicator of endometrial abnormality. The histopathologic diagnosis obtained at curettage is used as the gold standard. 74 women were included in this study. Endometrial cancer was not found with the endometrium= 5 mm thick. The mean endometrial thickness in those women with endometrial cancer was 13.72+/- 8.09 mm compared with 4.3 +/- 2.3 mm in those women with benign endometrium. If the cut off limit for endometrial cancer and hyperplasia was 5 mm, the sensitivity was 100% the specificity was 71.2%, the positive predictive value was 60%, the negative predictive value was 100% and the Kappa ratio was 0.6%. If this limit had been used in this study, 70% of the curettage procedures could have been avoided.
