Endometrial carcinoma usually occurs in postmenopausal women ; less than 5% occurs in women under the age of40. Up to one quarter of endometrial carcinoma patients below this age have PCO(polycystic ovary disease, Stein-Leventhal syndrome). The increased incidence of endometrial carcinoma in patients with PCO is related to chronic estrogenic stimulation. We report MR imaging in one case of endometrial carcinoma occuring in a 23 yearold woman with PCO and had complained of hypermenorrhea for about three years. On T2-weighted MR image the endometrial cavity was seen to be distended with protruded endometrial masses of intermediate signal intensity, and the junctional zone was disrupted beneath the masses. Both ovaries were best seen on T2-weighted MR imagingand showed multiple small peripheral cysts and low signal-intensity central stroma.

Ocular cicatricial pemphigoid isa chronic, progressive disease characterized by cicatricial shrinkage of the conjunctiva, entropion, trichiasis, xerosis, and finally reduced vision from corneal opacification. It is a relatively rare, autoimmune disease. In the early stages, it can be easily overlooked as simple chronic conjunctivitis, so it can be untreated. We report a case of ocular cicatricial pemphigoid that resulted in significant morbidity. We were able to control the progression of cicatrization with aggressive immunosuppressive therapy.

Beta-fluoroethylacetate has been extensively used as the rodenticide in Korea. In some patients with acute poisoning, beta-fluoroethylacetate caused cerebellar dysfunction as a single and persistent neurologic sequela after a period of an acute neurological disorder which is characterized by mental deterioration, seizures, and respiratory failure. But there has been no report of pathological findings to explain neurological deficit. We tried to verify the histologic changes of the central nervous systems in beta-fluoroethylacetate poisoned rats. Silver staining(Gallyas) was used to evaluate the histology. In acute intoxication experiment with LD50(7mg/Kg), beta-fluoroethylacetate elicited acute onset of consciousness deterioration, generalized tonic-clonic seizures and large amplitude tremulous activity involving whole body with full recovery after 24 hours. There was no discernible pathologic change in CNS in acutely poisoned rats. However, when poisoned with sublethal dose(5mg/Kg) daily for five days, a moderate degree of nerve cell degeneration was found selectively in dentate nucleus, Purkinie cell layer, vestibulo-cochlear nucleus and striatum. This change was not seen in hippocampus, cerebral cortex or cerebellar cortex. These findings were well correlated with the previous reports of selective pathology in human 5-FU intoxication cases. Our preliminary results suggest that beta-fluoroethylacetate, a kind of cellular metabolism inhibitor may induce selective neuropathology mainly involving cerebellar output pathway in rats.

24 eyes of 20 patients with increased intraocular pressure(IOP) or glaucoma that were not medically controlled or those who failed with previous glaucoma surgeries underwent Ahmed glaucoma valve implantation with intraoperative mitomycin C application. Mean follow-up period was 4.5 months (2-9 months) and mean preoperative IOP was 38.0 +/- 11.5mmHg. Mean IOP at last visit was 16.5 +/- 6.2mmHg and it was significantly lower compared to preoperative IOP (p<0.0001). One eye (4.2%) showed IOP less than 5mmHg at first postoperative day. When surgical success was defined as IOP less than 22mmHg and greater than 4 mmHg for 2 months or longer, IOP lowered by at least 20% from preoperative values (in eyes with preoperative IOP less than 22mmHg), and no additional glaucoma surgery or visually devastating complications, cumulative probability of success at 7 months was 69.1%. Qualified success (defined as lOP less than 22mmHg and greater than 4mmHg at last visit) rate was 83.3%. Complete success (IOP controlled as above without medication) rate was 66.7%. The complications included temporary shallow anterior chamber in 3 eyes, choroidal detachment in 3 eyes, fibrous membrane formation in anterior chamber in 3 eyes, hyphema in 2 eyes, tube malposition in 1 eye, corneal decompensation in 1 eye and tube blockage in 1 eye. This study suggests that Ahmed glaucoma implant provides good IOP control without significant postoperative complications including immediate postoperative period, and its success rate is comparable to the other seton implants.

Excimer laser photorefractive keratectomy(PRK) for myopia has been performed recently by refractive surgeons, in spite of myopic regression and corneal opacity following excimer PRK. We analyzed refractive change, corneal opacity, and uncorrected visual acuity of 313 eyes (233 patients) for one year and 115 eyes(83 patients) for two years after excimer PRK. The patients were divided tnto 3 groups accordign to theit refractive errors [group 1 (n=123 eyes): from -2.25D to -6D, group 2 (n=145 eyes) : from -6.25D to -10D, and group 3 (n=45 eyes): less than -19.25D]. Mean refractive errors one year after excimer PRK were -0.31+/-0.57D, -0.54+/-0.90D, and -1.71+/-2.01D in group 1, 2, and 3, respectively. These errors were increased to -0.45+/-0.68D, -0.90+/-1.20D, and -3.37+/-3.20D two years after excimer PRK in group 1, group 2, and group 3, respectively. These changes were staistically significant in group 2 (p=0.000) and group 3 (p=0.015), not in group 1 (p=0.426). Corneal opacity was more severe in group 3 than in group 1 and 2 and decreased depending on time passing by. Diopteric error within +/-1.0D from the attempted correction one year after excimer PRK was found in 89% of group 1, 74% of group 2, and 40% of group 3. These percentages were after excimer PRK. Uncorrected visual acuity equal to or better than 0.5 were 95% in group 1, 87% in group 2, and only 44% in group 3 two years after excimer PRK. With these results we thought that excimer PRK was effective and safe for myopia more than -6D, while unpredictable for myopia less than6D.

Causative bacterias of keratitis due to mishandling of contact lenses are mainly Gram negative rods, and large percentage of them are Pseudomonas. We experienced 6 cases of culture-proven Pseudomonas keratitis due to mishandling of soft contact lenses and wetting solution can be cultured. They are lack of education as how handle the contact lenses safely. And they did not done disinfection of the soft contact lens cases. To prevent contact lens related keratitis, we think it is very important for users to know its possible complication and how to use it and disinfect it safely.

This paper reports a case of a twisted small bowel obstruction in a 74-year-old man that occurred after a double tract reconstruction (DTR) in a laparoscopic proximal gastrectomy (PG) for early gastric cancer. The patient had inadequate oral intake and reflux symptoms for 10 days after discharge. Imaging analysis revealed a narrowed small bowel with twists between the esophagojejunostomy and gastrojejunostomy sites. A fully covered stent was placed in the narrowed small bowel for 2 weeks. The patient was then discharged after stent removal without any dietary problems. The authors’ experience shows that twisted small bowel after a DTR in PG can be treated by endoscopy.
