Background: Penetrating eye injury caused by mine explosion is a severe ophthalmologic injury. It is rare in Viet Nam and there were no studies on this type of injury. Objectives: To describe the clinical characteristics and evaluate the outcomes of surgery for penetrating eye injury caused by mine explosions. Subjects and method: The prospective analysis was conducted on 34 patients (36 eyes) with penetrating eye injury presented at the Trauma Department of Viet Nam National Institute of Ophthalmology. They were followed up for two years. Results: Out of the \r\n', u'34 patients, 31 were men (91.2%). Types of injury: corneal tear 93.8%, lens damage: 100%, vitreous damage: 56.3%, retinal detachment 25%, intraocular foreign body 72.2%. Initial visual acuity less than 0.02 was 96.9%. The final visual acuity was improved to better than 0.02 in 58.3% of patients. The intraocular pressures were normalized in 72.2% of patients after treatment. Conclusion: Penetrating eye injury caused by exploding mines has very severe clinical features. Despite of improvements in surgical techniques and instruments, the final visual acuity was still poor. The visual outcomes primarily depended on initial damages to the eye.\r\n', u'

Background: The post-traumatic glaucoma is a major cause inducing blindness of traumatic eyes. Recent, researches have shown that 5 fluoruoracil (5 FU) combined with surgery, which have a better result in treatment of general glaucoma and post-traumatic glaucoma. Objectives: To describe the clinical characteristics of post - traumatic glaucoma and assess the results of trabeculectomy with intra-operative application of 5 FU. Subject and methods: A descriptive, prospective analysis was taken on 32 patients, who had trabeculectomy with intra-operative application of 5 FU from August 2005 to December 2007 in the Traumatic Department of National Institute of Ophthalmology. Results: Post-traumatic glaucoma was seen mainly in young adults 71.9%; anterior angle recession combined lesions accounted for 25%; cataract 62.5%; fluid in anterior chamber 25%; anterior haemorrhage 37.5%. The intraocular pressure (lOP) was successfully controlled at least up to the following six months in 93.8% and the visual acuity was 0.02 and better in 62.5%. Conclusions: Trabeculectomy with antimetabolite therapy is an effective procedure in reducing IOP in post - traumatic glaucoma.

Background: Viet Nam is located in the epidemiological region of Japanese Encephalitis (JE). JE vaccine manufactured in Viet Nam has been used in the national vaccination program since 2003, but there has been no scientific study on the effectiveness of this program in Ha Nam province. Objectives: To investigate the epidemiology of JE and effectiveness of vaccinations in Ha Nam province from 2001-2006. Subjects and method: All residents in Ha Nam province, with the key focus group being JE cases. The retrospective and prospective epidemiological descriptive method was used. Results: The records of 148 cases of JE were collected. Among them, 42.5% (63 cases) were confirmed as JE by MAC-ELISA. The incidence and mortality rate were 1.29/100,000 and 0.12/100,000, respectively. Confirmed JE cases were found annually in all districts of Ha Nam province. However, it has been in decline, especially since the vaccination program was implemented for 1-5 year old children. The disease occurred in the summer with the peak in May and June (80.9% of total cases). Most of the cases were children under 15 years old (98.4%). The highest incidence rate was 6.4/100,000; 5.5/100,000 and 5.3/100,000 in the children aged 5-9, 1-4 and under 1 year old, respectively. Conclusion: The vaccination program appeared effective in reducing the mortality and morbidity of JE among children in Ha Nam province.

Background: Severe penetrating eye injury is a common emergency in ophthalmology. Objectives: The evaluation results and complications following vitrectomy in severe penetrating injury in children. Subjects and method: This study included 136 eyes with penetrating eye injury, who were treated at the Trauma department of National Institute of Ophthalmology, Hanoi \ufffd?Vietnam from 1999-2000. Vitrectomy was performed through the limbal and pars plana in 135 patients, 105 boys and 30 girls. Results: Remove intraocular foreign body: 11%, procedure for retinal detachments: 14%. The common functional success (visual acuity of 5/2000 or better) rate was 55,1%. Functional success: absent retinal detachment: 60,7%; present: 21,1%. Anatomic success rate was 66,2%. 4 eyes (2,9%) were eviscerated. Complications of the surgery were: iridocyclite, edema of the cornea, hemorrhage, hyphema. Conclusion:Vitrectomy techniques showed its good effect in treating penetrating eye injury in children. Presence retinal damage and endophthalmitis have significant effect on the final visual outcomes.

Background:The urocytogramme is a certain laboratory tests, although older. By studying the cellular elements from the wall of the bladder trigone desquamated in the urine, it allows cyto-hormonal diagnosis. It allows to assess the presence and importance of the biological effect of sex steroids. This examination is not commonly used because they are poorly known in our country. It's a review of how simple, noninvasive, inexpensive. Objectives:This study aims to learn about the value of urocytogramme in normal menstruation period of girls. Subjects and method:A study was conducted on 143 high school girls of Hai Ba Trung Secondary School, Hue city. The mean age was 15\xb18 months, completely puberty; the average weight was 45.7\xb16.8 kg; average height was 156.8 \xb18.5 cm. The duration of study was from September 2006 to May 2007. Results:Urocytogramme had the index which changed according to the phase of the menstrual cycle and correlated closely with sex hormone concentrations in the ovulatory phase. The IK index had the value in ovulation diagnostic phase with the sensitivity and specificity concentrations equivalent to LH and plasma Estradiol. Conclusion:Urocytogram was a useful test for the diagnosis of in normal menstruation period of adolescent girls. It was easy, cheap and truly reflected oestrogen activity to help doctors making decision for the treatment of lasting amenorrhea disorders.
