1.Studying on some predictors of hematoma enlargement occured in patients with hypertensive intracerebral hemorrhage
Journal of Vietnamese Medicine 2004;294(1):7-12
69 patients with hypertensive intracerebral hemorrhage (HICH) admitted within 24 hours of stroke onset. 14/69 patients (20.3%) with enlarged hematomas after the first CT was performed during 30 minutes at admission and the second within 24-36 hours of admission (33%). Multivariate analyses revealed that the following three factors were independently associated with hematoma enlargement: the time from stroke onset, prothrombin ratio, the shape of hematoma. Hematoma enlargement was an independent factor increasing the mortality rate in the HICH patients

Journal of Medical and Pharmaceutical Information 2004;0(2):21-24
Background: Antibiotic resistance is a popular condition, especially in hospitals. The development of multi-resistance strains of bacteria is a really interesting problem for the health branch. In Vietnam, antibiotic resistance surveillance programs are frequency performed, however, the results from them are limited. Objective: To determine the prevalence, component of bacteria species and the rate of antibiotic resistance of bacterial strains, which were isolated in the hospital. Subject and methods: 446 strains of pathogenic bacteria were isolated in Hospital 103 with routine microorganism technique. Antibiogramme was conducted with improved Kirby-Bauer technique. Results and Conclusion: Among these strains isolated in Hospital 103, the majority was the gram positive Cocci with Streptococcus spp (53.14%), S.aureus (19.73%). The gram negative was modest (under 10%). All the isolated bacteria were highly resistant to antibiotics (over 50%), except Augmentin. 29.85% of S.aureus resisted with Vancomycine.

Background: Heparansulfate Interacting Protein (HIP) is up-regulated in various human cancer cell lines at both transcript and protein levels. HIP expression is related to the differentiation status and cancer development. Objectives: To determine HIP in benign prostatic hyperplasia, prostatic intraepithelial neoplasia and prostate cancer tissues. Materials and method: Western blot method was used to determine HIP expression in 3 different types of prostate tissue, including 11 prostate cancer samples, 2 benign prostatic hyperplasia samples and 11 prostatic intraepithelial neoplasia samples. Results. HIP was particularly up-regulated in prostate cancer and prostatic intraepithelial neoplasia, indicating that up-regulation of HIP expression may be an early event in tumorgenesis. Conclusion: The expression of HIP was different between cancer, prostatic intraepithelial neoplasia tissue and benign prostatic hyperplasia. HIP may serve as a prognostic marker for prostate carcinoma.

Background: Nha Trang city located in central Viet Nam, has had dramatic economic development in recent years. The economic development has also leads to changes in the environment. Previous studies showed that cancers were closely related to environmental factors, but there was no study on this issue in Nha Trang city. Objectives: The study aimed to describe the cancer cases that were recorded in the cancer registration and the related environmental factors in Vinh Luong commune and the three neighborhood communes of Nha Trang city. Subjects and method: 192 patients who were diagnosed with cancer in the provincial general hospital and other hospitals from 1/1/2000 to 30/9/2006 and have resided in 4 above communes. Water samples collected from 14 water-wells from these communes were tested for chemical pollution and bacteria index. 20 sites in Van Dang village were tested for radioactive pollution levels. Results: Average crude morbidity of cancer per 100,000 inhabitants per year in Van Dang village and Vinh Luong commune and in the 4 communes as a whole, were 64.9, 51 and 53.3, respectively. The rates for male and female were 65.0 and 41.0, respectively. The most common cancers in women were cervical and breast cancers (11.8% and 9.2%, respectively). For men, leading cancers were liver cancer (31.9%) and lung cancer (14.7%). Almost all of the water samples did not meet the hygiene standard for nitrate (NO3) and coliform. Natural radioactive levels in these 4 communes were normal. Conclusion: Van Dang village had the highest cancer prevalence per 100,000 habitants compared to the other villages of Vinh Luong commune, but it was still lower than that of some other provinces. Most of the water samples collected from the water-wells did not met standard for nitrate levels and coliform.

Background: Fragile X Syndrome (FXS) is the most common cause of inherited mental retardation. The absence of Fragile X Mental Retardation (FMRP) in Fragile X syndrome changes other proteins. Objective: To detect changes of glycoprotein in human serum of Fragile X syndrome. Subject and methods: Affinity chromatography with lectin concanavalin A (ConA) used to receive glycoprotein. The collected glycoprotein was then separated using 2-D electrophoresis. The protein spots were further excised, trypsin digested, and analyzed by nano LC couple with ESI-MS/MS and identified by MASCOT v1.8 software. Results and conclusion: 5 glycoproteins showed the different expression levels in the serum of Fragile X syndrome. Haptoglobin, Ig-J were increased and ceruloplasmin, transferring, Ig kappa were decreased. Using affinity chromatography with lectin concanavalin A (ConA), glycoprotein was received and divided on 2 ways electrokinetic chromatography. The mixture protein was identified with a reliability of 99.5% by 2 ways liquid chromatography combined with continuous spectrum mass.

Background: Acute Respiratory Infection (ARI) is a common disease in developing countries. Morbidity and mortality of ARI are high, especially among children under 15 years old. Objectives: To describe socio-graphic factors, seasonal patterns, risky areas and determine the morbidity and mortality rates of acute respiratory infections in Thai Binh province. Subjects and method: This retrospective study reviewed the medical records of 4,585 hospital admitted patients who were diagnosed with ARI including upper and lower respiratory infections such as sore throat, pharyngitis, bronchitis, pneumonia and bronchitis-pneumonia at 8 district hospitals and 1 provincial hospital in Thai Binh province during 2002-2005. The selected medical records were based on the available check list and two standard screening tests. Results:Morbidity and mortality of ARI in Thai Binh province were 61.6 and 0.52, respectively. ARI mainly occurred among children under 5 years old, of which the highest mortality was among those under 12 months of age. Male children were at higher risk of acquiring ARI, but less prone to death than female. Occupation did not significantly associate with the risk of ARI. The morbidity increased sharply during inter-season, e.g. March and October. Thai Binh city, Kien Xuong and Tien Hai district were reported with the highest morbidity in accompany of the high mortality as consequences. Conclusion: The prevention and control methods were recommended to annually focus on the male children aged less than 5 years old during March and October in Thai Binh city, Kien Xuong and Tien Hai district.

BACKGROUND: In Vietnam, we observed a high incidence of carbamazepine (CBZ)-induced severe cutaneous adverse drug reactions (SCARs)-Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN), and drug-induced hypersensitivity rash with eosinophilia and systemic symptoms (DRESS). In other Asian countries, HLA-B*1502 is an established risk factor for SCARs. OBJECTIVE: The aim of our study was to determine the frequency of HLA-B*1502 in SCARs patients at a large University Medical Center in Hanoi, Vietnam. METHODS: Thirty-eight cases of SCARs caused by CBZ and 25 patients with epilepsy tolerating CBZ were enrolled in a case-controlled study. Clinical manifestations and laboratory findings were recorded for each subject. Genomic DNA was isolated using the QIAamp DNA purification system. The combination of polymerase chain reaction and sequence specific oligonucleotide probes with the Luminex 100×MAP flow cytometry dual laser system was then used to quantitate fluorescently labelled oligonucleotides attached to colour-coded microbeads. RESULTS: Cases comprised 20 SJS (52.6%), 7 TEN (18.4%), 8 overlap syndrome (21.1%), and 3 DRESS patients (7.9%). A strong association between HLA B*1502 and bullous skin reactions such as SJS/TEN and overlap was confirmed with an odds ratio (OR) of 33.78 (95% confidence interval [CI], 7.55-151.03), p < 0.0001, Sensitivity 91.4%, Specificity 76.0%, positive predictive value 84.2%, and negative predictive value 86.4%. We did not, however, observe any correlation between the presence of this allele and CBZ-induced nonbullous skin reactions (DRESS) (OR, 6.33; 95% CI, 0.48-82.74; p = 0.1592). CONCLUSION: Our results indicate the presence of HLA-B*1502 in Vietnamese is a pharmacogenetic risk factor for developing CBZ-induced SJS/TEN.

Little is known about antibiotic-resistant Gram-negative bacteria (GNB) intestinal carriage among healthcare workers (HCWs) in Vietnam. All HCWs at a tertiary intensive care units were asked to undertake weekly rectal swabs. Among 40 participants, 65% (26/40) carried extended spectrum β-lactamases (ESBL)/AmpC β-lactamase-producing Escherichia coli. Two HCWs colonized with ESBL/AmpC β-lactamase-producing Klebsiella pneumoniae. One HCW colonized with Acinetobacter baumannii. No one carried Pseudomonas spp.. A quarter (10/40) of HCWs were identified as persistent and frequent carriers. There is an urgent need to screen antibiotic-resistant GNB among HCWs and improve HCWs' hand hygiene compliance to reduce the transmission of antibiotic-resistant GNB in the hospital.

Despite their being uncommon, severe cutaneous adverse drug reactions (SCARs) result in a very great burden of disease. These reactions not only carry with them a high mortality (10%–50%) and high morbidity (60%) with severe ocular complications, alopecia, oral and dental complications and development of autoimmune diseases, but also create a substantial economic burden for patients' families and society. SCARs are, therefore, an important medical problem needing a solution in many countries, especially in Asia. The clinical spectrum of SCARs comprises Stevens-Johnson syndrome, toxic epidermal necrolysis, DRESS (drug rash with eosinophilia and systemic symptoms) (also known as drug hypersensitivity syndrome or drug-induced hypersensitivity syndrome) and acute generalised exanthematous pustulosis. Recent crucial advances in determining genetic susceptibility and understanding how T cells recognise certain medications or their metabolites via the major histocompatibility complex and the effects of cofactors, have led to the implementation of cost-effective screening programs enabling prevention in a number of countries, and to further understanding of the patho-mechanisms involved in SCARs and their significance. In this review, we document comprehensively the journey of SCARs from bedside to bench and outline future perspectives in SCARs research.
