The Arnold-Chiari malformation (ACM) is an anomaly of the hindbrain consisting of two components: a variable displacement of a tongue of tissue derived from the inferior cerebellar vermis in the upper cervical canal and a similar caudal dislocation of the medulla and fourth ventricle. Hydrocephalus and meningomyelocele are another abnormalities that associated frequently. We present a case of Arnold-Chiari malformation with hydrocephalus and meningomyeolcele and a brief review of the literatures was added.

Many authors reported the etiology of hypoplasia of the nasomaxillary complex as trauma, infection, underdevelopment. To correct these deformities, Le Fort II Osteotomy and its modification has been popularly applied. This method enabled total advancement of nasomaxillary complexes and acquirememt of midfacial esthetics. But it has some limitations such as various occlusal deviation or lateral shifting of nasomaxillary complex in case of nasomaxillary retrusion. We grouped these patients as follows : 1. Nasomaxillary retrusion without shifting of nasomaxillary complex (1) Anteroposterior deviation of occlusal plane (2) Lateral deviation of occlusal plane(including canting) (3) Supero-inferior deviation of occlusal plane (4) Combined disturbance of occlusal plane without shifting of nasamaxillary complex 2. Lateral shifting of nasomaxillary complex with or without deviation of occlusal plane We performed Le Fort II and I combined osteotomy on eleven cases of midfacial deformity from June 1994 to July 1997 and in most of the cases, followed up maximum 36 months and could acquire positional stability and improvement of facial eathetics.

PURPOSE: To compare the clinical results of hydrophilic acrylic IOL 570H (Centerflex(R), Rayner, UK) with those of hydrophobic acrylic IOL MA60BM (Acrysof(R), Alcon, USA). METHODS: Centerflex(R) and Acrysof(R) were each implanted in one eye of 31 patients with bilateral cataracts. We evaluated and compared best corrected visual acuity (BCVA, logMAR), refractive error, anterior capsular fibrosis, and posterior capsular opacification at mean 9.3 months after surgery. RESULTS: BCVA (logMAR) was 0.04 +/- 0.07 in the Centerflex(R) group and 0.03 +/- 0.07 in the Acrysof(R) group. There was no statistically significant difference between the two groups. Refractive error was -0.23 +/- 0.76 diopter (D) in the Centerflex(R) group and 0.09 +/- 0.61 D in the Acrysof(R) group. There was a statistically significant difference of refractive error between the two groups (p=0.02). In the Centerflex(R) group, the rates of both anterior capsular fibrosis and posterior capsular opacification were statistically significantly higher than those in the Acrysof(R) group (both, p=0.05). CONCLUSIONS: We found no statistically significant difference of postoperative visual acuity between Centerflex(R) and Acrysof(R) lenses implanted in the bag after phacoemulsification. However, mean refractive error in eyes implanted with Centerflex(R) lens was -0.23 D at mean 9.3 months after surgery and we recommended that the preoperative target refraction of the Centerflex(R) lens be 0.23 D hyperopic and that postoperative anterior capsular fibrosis and posterior capsular opacification be checked carefully.

PURPOSE: In patients with small or large aneurysms, the decision for surgical treatment is not so simple. The mortality of ruptured abdominal aortic aneurysm (AAA) is high. This study was designed to retrospectively analyse the clinical characteristics of patients with AAA. METHODS: Ninety-one cases of AAA were surgically treated between January 1991 and January 2003 at the Department of Surgery, Chonnam National University Hospital. Patients were divided into 49 elective cases and 42 emergency cases, and retrospective analysed on the basis of age, sex, chief complaints, physical examination, associated diseases, size of aneurysm, diagnostic modalities, operative mortality and causes of death. RESULTS: The initial presentations were mainly palpable masses in the elective cases. On the other hand, in the emergency cases which were ruptured, many patients complained of abdominal or back pain. There was a positive relationship between the size of AAA and the incidence of the rupture in our study, especially in the case of transverse diameters above 10 cm (P<0.001). There was no death in the elective cases, but there were 22 surgical mortalities in the 42 emergency cases (52.3%, P<0.001). Overall surgical mortality was 24.1%. The causes of death were intraoperative and postoperative bleeding (11), myocardial infarction (5), acute renal failure (4), and sepsis (2). CONCLUSION: Surgical mortality in ruptured AAA was high. Consequently, surgical intervention is recommended and the operation must be performed. In that way we can reduce the operative mortality and improve the treatment outcome.

PURPOSE: To investigate the trend of refractive change in hyperopic patients according to increases in age. METHODS: Eighty-eight children who had hyperopia of more than +1.50 diopters (D) and could be followed up for at least 5 years were included in this study. We divided the patients into two groups according to the level of initial hyperopia and retrospectively analyzed hyperopic refractive changes over a 5-year period according to age at initial diagnosis, presence of esotropia, amblyopia, astigmatism and anisometropia. RESULTS: We gained the following formula about the aspect of hyperopic reduction in 88 patients over a period of 5 years: Diopter (D)=7.99-2.14 Ln (age). The presence of anisometropia and amblyopia did not affect hyperopic reduction. Hyperopic reduction amounts in the group with a hyperopic eye of more than +5D at initial diagnosis were greater than in the group with a hyperopic eye less than +5D, and greater in the group with an astigmatic eye of more than 1D. The presence of esotropia and the age at initial diagnosis did not affect hyperopic reduction. CONCLUSIONS: We show that emmetropization in hyperopic children occurs according to the following formula: Diopter (D)=7.99-2.14 Ln (age). Both the initial level of hyperopia and the concurrent presence of astigmatism affected hyperopic reduction. However, the presence of anisometropia, amblyopia, esotropia and the age at initial diagnosis did not significantly affect hyperopic reduction.

OBJECTIVE: To assess the effect of recombinant human leukemia inhibitory factor on in vitro development of 1-cell ICR mouse embryo. MATERIALS AND METHOD: ICR mice were superovulated with PMSG/hCG and 1-cell stage mouse embryos were recruited. 1-cell mouse embryo were cocultured on human oviductal cells in a CO2 incubator (coculture group) and were cultured on 0.4% BSA+HTF media (control group). And anti-hLIF Ab was added the cocultured group in a different concentration (1pg, 10pg, 100pg, 1ng) and developmental rate was compaired to the control group, and rhLIF was added to the preincubated 0.4% BSA+HTF media in a different concentration (2000U, 1000U, 100U, 10U) and its developmental rate was compaired to group which was cultured on 0.4% BSA+HTF media only. RESULT: 1. The cleavage rate of 2-cell mouse embryo co-cultured with human tubal epithelial cell was significantly higher than that of cultured with media alone (HTF with 0.4% BSA) (p<0.05). 2. When LIF antibody was added to the medium with human tubal epitherlial cell, the mouse embryo could not cleave more than 2-cell in 1 ng of LIF antibody, and less than 1 ng, the cleavage rate was lower than cultured without LIF antibody group(p<0.05). 3. Two cell blocked ICR mouse embryos were developed into four cells under LIF(p<0.05), but no further development was observed. CONCLUSIONS: These results shows that LIF enhances the development of preimplantation embryo, and when rhLIF is applicated in vitro, it has positive effects on the development of early mouse embryo and can help overcoming the two-cell block.
