Studies of 805 samples until 10/2004 show that the malaria prevalence was high in the first 5 months in 2003, among 7 deaths were unorganized migrants. They contract malaria all year round, especially in the beginning of the year with the highest of 11.96% in February. The density of maralia parasite (+) was high in months at the beginning and end of the year such as January, April and October with the density in the first month of 2.92%. Spleenomegaly was mostly seen in age 5-14 with 3.17% and mostly in grade I and II (97.8%). Spleenomegaly grade III and IV is predominated in over 14 years old group (60%). Vectors at the first three months of the year were high and various in species in accordance with the malaria prevalence. An. dirus and An. minimus as the two main vectors of transmitting were present in almost of the year both house inside and outside, which is the cause for the transmission

Survey 140 patients with tubal factor infertility at Tu Du Hospital from 2002 to 2003. Intrauterine pregnancy rate was 19.3% and ectopic pregnancy rate was 9.3%. Patient’s age is one of factors influencing the outcome of laparoscopic surgery. The elder patients are, the lower pregnancy rate they get (for patients over 35 years old, pregnancy rate is as low as 4%). The level of tubal damage and adhesion are also influencing factors for rate of intrauterine pregnancy. The more severe damage and adhesion patients had, the lower pregnancy rate they get. The prognosis of tubal factor infertility was highly associated with the level of tubal damage and patient’s age. Laparoscopic surgery for tubal obstruction is only effective for cases with mild or moderate lesion. For elder cases over 35 years old or severe tubal damage, IVF-ET should be indicated

Some techniques of detection of Hib were compared, including classic techniques such as bacterial culture and modern techniques such as PCR method. The results were as follows: 21% (+) culture with Hib compared to the total of clinically diagnosed cases, Hib-latex agglutination with 95% sensitivity and 99.6% specificity, counter immunophoresis assay to detect Hib by 97% sensitivity and 100% specificity. PCR increased the number of positive cases of Hib meningitis by 42.8% compared to culture alone. Blood culture gave a highly significant value to diagnose (51% Hib-possitive culture)

There is about 30% of women experienced uterine fibroma and most of them needn’t treatment. For symptomatic women, various medical treatments were more and more extensive. Surgical treatments were indicated depending on many factors and individual patient. Besides traditional therapies (myomectomy, hysteroscopic myomectomy, uterine endoscopy, etc), there were more and more new techniques such as uterine artery embolization. This technique is relative new and minimal invasive of management, but it still needs further research

Isolate, purify, and identify bacteria from probiotic supplement. Results: 5 strains of lactic bacteria were determined, including: Steptococus feacalis; Streptococcus lactic; Bifidobacterium bifidum; Lactobaccillus acidophilus; Lactobacillus casei. Study the sensitivity of these bacteria with antibiotics, results showed that these bacteria were resistant to many antibiotics, especially oral antibiotics. Conjugative trial between Streptoccocus feacalis, Streptococus lactic, Bifidobacterium bifidum, lactobacillus acidophilus casei and E.coli K12, and conjugative trial of lactic bacteria together showed negative results. Therefore, probiotic product contained many lactic bacteria can be used concomitant with some oral antibiotics to prevent or treat digestive disorders

The study was conducted to compare the molecular differences of Haemophilus influenzae type b (Hib) strains causing meningitis in young children with H. influenzae strains causing acute upper respiratory tract infection, 44 Hib strains and 37 H. influenzae strains were analysed by pulsed field gel electrophoresis (PFGE) with SmaI restriction enzyme. The results: 44 Hib strains were mainly distributed into 4 DNA restriction patterns (PFGE patterns) whereas 37 H. influenzae strains were distributed into 22 patterns and 81% of them were not encapsulated. The genome of Hib strains causing bacterial meningitis showed less variation than that of H. influenzae causing acute upper respiratory infection. PFGE is a useful tool for epidemiological research.

A portion of 652bp of mitochondrial-encoded cob gene was amplified by polymerase chain reaction (PCR) from different Taenia sp samples (tspVN1-10) of different forms of adult, cysticercus isolated in Vietnam. The nucleotide and amino acid sequences of Vietnamese Taenia sp samples were comparatively aligned with the known corresponding sequences of other Taenia species in GenBank. Results showed that TspVN1-3 is Taenia asiatica, TspVn4-6 is Taenia saginata, and TspVN7-10 is Taenia solium. The Vietnamese T.solium is clustered with the Asian T.solium species, while the Vietnamese T.asiatica is clustered with Taiwanese and T.saginata together with the Chinese T.saginata isolate

A region of 326 bp of mitochondrial cytochrome oxidase 1 (cox1) for Opisthorchis sp sample collected in An My, Tuy An, Phu Yen, was amplified using PCR. Nucleotide sequence of this cox1 fragment was used to comparatively analyzed with that of O. viverrini, strain Khon Kaen, Thailand, and C. sinensis sequences of Opisthorchis sp of Vietnam, China and Korea. The analysis revealed that nucleotide sequences of Opisthorchis sp of Vietnam has absolute homology to O. viverrini strain Khon Kaen, Thai Lan, but difference from C. sinensis originated from Vietnam, China and Korea. Opisthorchis sp of Vietnam isolated in Phu Yen is, thus, molecularly identified as Opisthorchis viverrini. This gives rise to establish a diagnostic approach and aspect of preventive/control for these species

The prevalence of caries of milk teeth was 62.6% of 6-10 -year -old age school children in Bac Kan province. There was no difference between boy and girl. 78.5% was the prevalence of periodontosis diseases. Candy consumption was a risk factor for caries (OR=4.62) and periodontosis (OR=0.15). For caries, no brushing of teeth was a risk factor (OR=4.54) and a factor causing high prevalence of periodontosis in children

Transport for pediatric patients from one department to another ones in the same hospital or from one hospital to another must be sure of their safety and during the transportation, the patients’ situation were followed up and treated appropriately. The patient needs to move to a better place that includes care condition and treatment or where the explorative tests can be done to server for diagnosis and treatment
