Our study included 14 patients admitted to Bachmai hospital because of headache and hypertension after taking anti-cold preparations (Rhumenol Decolgen, Decolsin, and Medicoldac) from 3/2002 to 6/2002. These patients had no history of hypertension and took antiflu tablets according to instruction of manufacturers. On admission, all patients had hypertension with the maximum BP 190/120mmHg. The first-degree atrioventricular block was observed in 1 case. The adverse effects may be caused by overdose of phenylpropanolamine, a sympathomimetic agent. Our study is a warning of dangerous reality of broadly advertising, marketing and abusing drugs. The manufacturers should consider the amount of Phenylpropanolamine in anti-cold preparations to avoid the adverse effect.

The vertical HIV transmission from mother to infant can occur in the pregnant period (in utero), during labor or after delivery from breastfeeding. It’s difficult to diagnose HIV-infected newborns by means of serology test, since IgG antibody can infiltrate through placenta from HIV-infected mothers and therefore the serology test is always positive in their babies, even in case the babies were not HIV-infected. In this study, the vertical mother-to-infant HIV-1 transmission in utero was detected by using polymerase chain reaction (PCR) with p17, c2v3 (gp120) and gp41 primers. 37 of 37 (100%) mother blood specimens and 2 of 37 (5.4%) their newborn umbilical cord blood samples were HIV-1 PCR positive. The PCR success rate with P17 and gp41 primers was much higher than that of PCR with c2v3 primer, especially on umbilical cord blood samples. It is recommended that a PCR test using the least 2 primers (p17 and gp41) should be performed at birth to detect HIV-1 seropositive infants and to allow the initiation of antiretroviral therapy. It is necessary to follow up baby health and perform repeatedly HIV-1 PCR on their blood samples to diagnose the timing of HIV-1 transmission.

From August 1996 to April 2002, 453 cacses of laparoscopic cholecystectomy were performed in Hospital 108. Their 8 patients suffered from bile duct injury (1.8%). 50% had transection, 25% had incisions, 25% had cystic duct leak. For treating, simple suturing with Kehr draining tube 37.5%, draining tube interested in abdomen cavity 50%, Roux en Y choledochojejunostomy 12.7%. Post operative result was good in 75% of cases and in 24% there was a leak in anastomosis site

Blindness prevalence and its causes are necessary for planning of the Blindness Prevention activities. Objectives: to evaluate blindness prevalence and causes, the output and outcome of cataract surgical services in the community. Methods: Cross-sectional prescriptive study was conducted on 1,729 persons of 50 years old and over. Results: Bilateral blindness prevalence is 3.41%, monocular blindness prevalence is 7.63% in the group of 50 years old and over. Main causes of blindness are cataract (47.5%), pathology of posterior segment (22.0%), glaucoma (16.9%), trachoma (3.4%). Bilateral and monocular cataract-related blindness rates are 1.50% and 3.76%, respectively. Prevalence of TT in one eye is 4.22%, in both eyes is 2.66%, prevalence of Pterigyum in one eye is 19.56% and in both eyes is 7.99%. The bilateral aphakia rate is 1.39%, monocular aphakia rate is 2.37%. The cataract surgical coverages are 63.89% of patients and 43.20% of eyes. The successful surgical rate is 67.42%. Main barriers for cataract management service are poverty (23.1%), unawareness (18.2%), and no accompaniers (9.1%). Conclusions: Main cause of blindness in Hanam is still cataract. The CSSR is good but the successful surgical rate is not high. In the next 10 years promotion of cataract surgery output and surgical quality should be done in order to reduce blindness prevalence.

Retrospective 138 official documents and resolutions about drugs which fail to meet the qualitative standard on total number of 200 consulted documents (115 from ministry echelon due to Vietnamese drug administer bureau granted and 23 from office echelon due to Office of Health of Ho Chi Mink city granted. Result showed that: 20 among 23 drugs fail to meet the qualitative standard that found in office echelon were domestic oriental medicine. Handling breaches decisions for foreign oriental medicine were main for China. Number of domestic drugs and foreign drugs were approximate.

The aim of this study is to describe some maxillary sinuses parameters of Vietnamese adults by multislice computed tomography from January 2005-June 2005 at the Post and Telecommunication No2 hospital. Results: jaw cavity have horizontal diameter of 3.177cm, pre- rear diameter 3.99cm, top-bottom diameter 3.9517cm… Besides the anatomical description characteristics, the initial results of this study are very important to endoscopic surgery via nasal sinus.

Diarrhea continues to be one of the most common causes of morbidity and mortality among infants and children in developing countries. Escherichia coli are an emerging agent of pathogens causing diarrhea. Among 587 fecal samples from Vietnamese children under five years of age with diarrhea, the PCR technique identified 68 samples (11.6%) positive with EAEC and 18(7.2%) among the 249 age-matched controls showing the significant difference. In the diarrhea group, the significantly higher prevalence was seen in the children less than two years of age as compared to the older ones. There is a decreasing tend of EAEC infection during the age. When comparing the children at the age of less than 12 months, the prevalence of EAEC was significantly higher in the diarrhea group than in the control. More studies need to be carried out to verify the role of EAEC in causing diarrhea in children.

Study on adults patients who were multislice computed tomography of craniofacial at the Post and Telecommunication N02 hospital from January to June 2005. In 51 cases there were 22 males and 29 females, age from 22-56 years. 102 sinuses were studied. Results: the diameters of sphenoidal sinus were measured by the greatest diameter with 3 Sagittal Coronol and Axial planes. The general size of sphenoidal sinus: horizontal diameter 1.932 cm, anterio-posterio diameter 2.347 cm, superio-posterio diameter 2.483 cm, superior-inferior diameter 3.156 cm, capacity 3.727 cm3. The technique of multislice computed tomography was the basis and necessary technique not only for diagnosis but also for the base of services in treatment.
