An evaluation of the situation of the country’s nuclear medicine department and the use of radioactive resources in Vietnam was implemented. Currently Vietnam has 200 equipments for X-ray generation, 28 radioactive resoureces; 7 centres and 22 facilities of the nuclear medicine which served millions patients everyear. This study also evaluated the networks of X-ray machines and other related medical equipment. From which the orientation and solutions for use of the radioactive resources and radioactive safety in Vietnam were recommendated

Background: In recent year, provinces in coastal south west area have many changes in environment which makes difficult to manage the epidemiology of malaria. Objective: To investigate ecological character of An.epiroticus in newly salinized areas of Can Duoc distrist, Long An province. Subject and Method:The investigation of An.epiroticus and environmental factors was carried out in newly salinized areas in Can Duoc district, Long An province from 2006- 2007. Result and Conclusion: The result showed that An.epiroticus populations in both zones categorized as shrimp-rice fields and brackish shrimp fields were anthropophilic. This species bites human both in and outdoor throughout the night with peak of biting rates were from 20h00 to 02h00. A considerable number of An.epiroticus was found to rest indoors in the morning. This species in studied site was resistant to both Alpha-cypermethrin and Lambdacyhalothrin. The larvae of An.epiroticus were mainly found in stagmant or slow running brakish water bodies having salinity of 1.0 to 3.5 g of NaCl/litre; pH = 7.0 - 8.0; temperature 28 - 30\xb0C; with presence of aquatic plants.

A 40 year-old female was admitted to our hospital because of proptosis for 4 years. Detecting a 2 cm-sized retrobulber mass on computerized tomography, we extracted well capsulated reddish brown mass, which confirmed as a cavernous hemangioma by histologic examination. One year postoperatively, her proptosis was gone, visual acuity was normal, and ocular motility was good.

While advancements in microsurgical technique and suture material have led to meticulous wound closure in cataract surgery, excessive postoperative corneal astigmatism may delay visual recovery and compromise the ultimate optical outcome. Greater efforts to prevent and control surgically induced astigmatism have been made recently since the introduction and popularized use of intraocular lenses. Control of astigmatism has been attempted with intraoperative variations in the size, location, and type of incision, the selection of suture material, attention to suture depth and technique, the use of preplaced sutures to facilitate wound closure, and most recently, the application of surgical keratometers. We reviewed follow up records to evaluate and compare the influences on corneal astigmatism after extracapsular cataract extraction(ECCE) with intraocular lens implant in 100 cases of polyglactin 9l0(vicryl) group and 50 cases of polydioxanone (PDS) group, and results were as follows; 1. In planned ECCE group, mean corneal refractive power changes was -0.14D +/- 0.47 in vicryI group and -0.17D +/- 0.78 in PDS group, there was no significant correlation between two. In phacoemulsification(KPE) group, mean corneal refractive power changes was 0.05D +/- 0.49 in vicryl group and 0.27D +/- 0.82 in PDS group. There was no significant correlation between two. 2. In total group, mean corneal refractive power changes was 0.02D +/- 0.48 in vicryl group and 0.08D +/- 0.74 in PDS group. There was no significant correlation between two groups. 3. Mean power of cylindrical lens for correction of astigmatism was -0.76D +/- 0.98 in vicry I group and -0.67D +/- 0.71 in PDS group, there was no significant correlation between two.

The severe gummy smile and a skeletal class II profile pose challenges in treatment. This case report outlines an effective alternative for addressing these problems in a patient with skeletal class II division 2, class II molar relationship, retroclination of upper incisors, and lip protrusion. Treatment objectives included normalizing the overjet and overbite, improving the gummy smile, and establishing a satisfactory occlusion. A three-dimensional simulation was performed to consult with the patient, assess possible results, and predict treatment biomechanics. The treatment involved the use of two zygomatic and one inter-radicular temporary anchorage devices, along with botulinum toxin. After the 2-year follow-up, a satisfactory dental occlusion, aesthetic improvement, and adequate function were achieved. This approach offers a viable alternative to orthognathic surgery for adults with skeletal class II malocclusion and a severe gummy smile due to hypermobile lip.

We evaluated 247 corneal ulcers of 28,004 OPD patients in whom materials from corneal scrapings were routinely plated on Sabouraud's glucose agar and thioglycolate broth for fungal and bacterial culture, respectively, at the Chonnam National University from January 1981 to July 1987. The results were as follows: 1. Corneal ulcers were 0.9%(247 cases) of 28,004 OPD patients; the highest, 1.3%(41 cases) in 1981 and the lowest, 0.6%(33 cases) in 1986, and the frequency decreased slightly in the last seven years. 2. Of the corneal ulcers, bacterial ulcers were 64 cases(25.9%), fungal, 51 cases(20.6%), herpetic, 40 cases(16.2%) and 92 cases(37.3%) were unknown in causative organism. 3. Of the 51 fungal origin, 24(47.1%) were men, compared to 27 women(52.9 %), and 28 cages(54.9%) were in the 40's and 50's. 4. Fungal or anisms were isolated from 51 cases(20.6%) of 247 corneal ulcers; the peak incidence was 39.4%(13 cases) in 1986 and the lowest, 8.8%(3 cases) in 1983. 5. Isolated fungi were categorized into 8 species, 9 groups including 21(41.2%) Fusarium sp., 17(33.3%) Aspergillus sp., 5(9.7%) penicillium sp., 3(5.8%) Candida albicans, 2(4.0%) Trichophyton rubrum and 1(2.0%) Alternaria sp., Streptomyces sp. and Paecilomyces sp., respectively. 6. The seasonal peak was in the summer (June to August); the onset peaked from May through October, 33 cases(64.7%), and 18 cases(35.3%) developed in the months of November through April. 7. With the treatment of oral and topical ketoconazole, successful outcome was achieved in 24 cases(61.5%) of the 39 cases treated at our Dept. continuously at least for a week, and the duration of treatment was averaged 24 days.

Preoperatively normotensive 211 cases of extracapsular cataract extraction (ECCE) and posterior chamber lens implantation in the capsular bag had intraocular pressure (IOP) measurements recorded 3 months postoperatively. Analysing the data of IOP level, surgical technique (planned extracasular cataract extraction or Kelman phacoemulsification), age, sex and corneal curvature, we could find the following results. 1. The mean change in intraocular pressure (postoperative IOP minus preoperative pressure) was -0.8 mmHg. 2. In 8 cases(3.8%) of 211 eyes postoperative IOPs were higher than 21 mmHg. 3. The higher preoperative IOP level was, the more the decrease of postoperative IOP was. 4. The changes in intraocular pressure was more significant in females than males. 5. There was no significant change in IOP level according to the age, surgical technique and corneal curvature.
