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.

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.

212 patients suffering from colorectal cancer are analyzed, the author have following remarks: 1. Colorectal cancer generally occurs in individuals 40 years of age or older. Ration of men to women: 1.82. 2. Incidence of malignant lesion: rectum 36.32%, sigmoid: 16.04% righ colon: 15.57%, left colon: 14.15%, tranverse colon: 8.02%, cecum: 9.09%. 3. Treatment: right hemicolectomy 20.75%, left hemicolectomy: 7.55%, colectomy: 14.62%, subtotal colectomy: 2.83%, miles: 14.15%, artificial anus: 30.19%, by-pass: 3.77%, exploration: 1.42%. The early results of post operative: post operative complications were: 8.9%; post operatative: post operative mortality was:1.98%.

This retrospective study was undertaken to characterize the endoscopic and histopathologic pattern of patients with gastro-esophageal reflux with esophagistis. We investigated 58 patients (24 women, 34 men: mean age 44.33 years). The histopathologic pattern was classified in 3 grades: Grade 1: 19 patients, grade 2: 18 patients, grade 3: 21 patients. The sex ratio, age, endoscopic and particular histopathologic pattern was discussed. We conclude that the gastro-esophageal reflux disease is a common complaint in adult population. Despite it is not a severe damage, it can complicate to Barret’s oesophagus, a premalignant lesion of esophageal adenocarcinoma.

The analysis showed that 207 mothers (78% of the cases) had never received tetanus toxiod. 96% (254) of the cases did not meet the criteria set for "protection at birth", 73.8% of the mothers did not seek antenatal care. The rate of delivery at home was 71%. The rate of delivery by traditional birth attendants (TBA) was 50%.

To determine the validity of the following simple criteria used to determine protection of the infant from neonatal tetanus, we carried out an analysis of 646 neonatal tetanus cases that were reported in Vietnam from 1994 to 1998. 93% (602) of the 646 cases did not fit the criteria set for “protection at birth”. It was concluded that the criteria used to define “protection at birth” are valid and reliable. It's enough to be used by health workers as a simple management tool to monitor the neonatal tetanus elimination program, and assess the eligibility of women for further tetanus toxoid doses, according to the EPI schedule.

The authors presented 37 cases of thymomas operated at Viet Duc Hospital during 1998-2002. The results: 31 males and 6 females with medium age 46.8. The microscopic features were: medullary thymoma: 1, mixt type: 6, predominantly cortical thymomas: 4, cortical thymomas: 4, squamous cell carcinomas: 11 (4 keratinazing and 7 nonkeratinazing, basaloid carcinomas: 2, clear cell carcinoma: 1, small cell carcinoma: 6, sarcomatous carcinoma: 1 and anaplastic carcinoma: 1. Eleven cases developed the superior vena caval syndrome and most of these indicated the malignancy in the microscopic features. The relations between clinical and pathological aspects were discussed.
