Dementia is defined as a syndrome which is characterized by various impairments in cognitive functions, especially memory function, Most of the diagnostic criteria for dementia include memory impairment as no essential feature. Memory decline can be present as a consequence of the aging process, But it does not cause significant distress or impairment in social and occupational functionings while dementiadoes. Depression may also be associated with memory impairment. funcitionings while dementiadoes. Depression may also be associated with memory impairment. However, unlike dementia, depression dose not cause decrease in delayed verbal learning and recognition memory. In dementia, different features of memory impairment may be present depending on the involved area. Memory impairment in cortical dementia is affected by the disturbance of encoding of information and memory consolidation, while memory imparnene in subcrotical denentiy is affected y the disturbance of retrieval in subcortial dementia.

PURPOSE: To evaluate the efficacy of the KR-1W aberrometer in assessing the astigmatism and the achieved axis after AcrySof Toric intraocular lens (IOL) implantation. METHODS: Thirty-nine patients (48 eyes) that had undergone phacoemulsification and AcrySof Toric IOL implantation were included in the present study. At postoperative 1 month, ocular aberrations of all the eyes were measured using the KR-1W aberrometer before mydriasis and the achieved axis of AcrySof Toric IOL was measured by slit lamp examination after mydriasis. The achieved axis measured by slit lamp examination and the astigmatism of the implanted AcrySof Toric IOL were compared with the KR-1W. RESULTS: The mean achieved lens axis after mydriasis measured by slit lamp examination and KR-1W was 86.43 +/- 47.49 degrees and 88.93 +/- 41.22 degrees, respectively. The correlation coefficient of the 2 methods was 0.992 (p < 0.001). The measured astigmatism according to the AcrySof Toric IOL model was 1.11 +/- 0.47D in SN60T3, 1.71 +/- 0.51D in SN60T4, and 3.32 +/- 0.78D in SN60T5. CONCLUSIONS: Without the need to directly evaluate the axis of implanted Toric IOL after mydriasis, the achieved lens axis can be measured by the KR-1W without mydriasis. The AcrySof Toric IOL model could be assessed by the KR-1W without information about the AcrySof Toric IOL model.

This study was undertaken to evaluate the status of human paragonimiasis in Kang Hwa Gun, Kyunggi Do, Korea from March 1973 to October 1975 by the use of intradermal screening test with Veronal buffered saline antigen. A total number of 7,352 (male 3,936; female 3,4l6) consisting of 3,447 primary school children, 2,689 middle school students, l,008 high school students of 9 Myuns out of 13 Myuns of this County and 208 residents of all age group in Kilgeong-Ri, Yangdo Myun were examined by the intradermal test with Paragonimus antigen. In order to detect Paragonimus egg, the sputum and the stool examinations were undertaken on the residents in Kilgeong-Ri. The infestation rate of crayfish with Paragonimus metacercaria was also examined in Konneung and Jeongha village in Kilgeong-Ri. The following results were obtained in this survey: As a whole, 16.6 per cent of the examiners showed positive reaction with sexual difference of 16.1% in male and 14.8 per cent in female. In age groups, the highest positive rate showed in middle school age group (17.1 per cent) than primary school (14.0 per cent) and high school age group (11.4 per cent). In regional differences of positive rates, the highest rate (28.4 per cent) showed at Yangdo Myun followed by Kilsang Myun (27.0 per cent), Hwado Myun (25.0 per cent), and Naega Myun(20.8 per cent). In the result of 208 residents Kilgeong-Ri, the positive of 36.1 per cent in male and 20.2 per cent in female. The highest positive rate showed in 10 to 19 age group (41.5 per cent). Among the residents in Kilgeong-Ri, Paragonimus eggs were detected in 11 residents by the sputum and the stool examinations. The infestation rate of crayfsh with Paragonimus metacercariae was 100 per cent (41 out of 41 crayfishes) in Konneung village, and 84.6 per cent (9 out of 13 crayfishes) in Jeongha village, Kilgeong-Ri The fluctuation of the infection rate of crayfish with Paragonimus metacercariae was decreased in Konneung village in 2 years after the treatment with Bilevon against 10 paragonimiasis patients.

We developed an animal model to recreate the condition of an open fracture in communication with the maxillary sinus. We then studied wound healing of the sinus wall structures following fracture in the presence of autogenous bone and alloplastic implant. This model is designed to simulate the repair of an orbital floor fracture in humans. The New Zealand White rabbit was used as the animal model. Standardized 8mm defects were made bilaterally in the maxillary sinuses to include bone and mucosa in 36 rabbits. Two different implants and autogenous calvarial bone graft were placed in the soft-tissue pockets to obturate the defects, exposing one surface of the implant to the open sinus. Medpor porous polyethylene, silicone and calvarial bone implant were compared. Animals were killed at 1, 2 and 8 weeks after implantation. Gross examination of the specimens for the amount of mucosal closure and implant tissue fixation was performed. Histological sections were evaluated for bone and soft-tissue morphology juxtaposed to the implant. Complete closure of the mucosal defect was demonstrated with each type of implant. Medpor implants showed both vascular and soft-tissue ingrowth into pores by week 1. Bone ingrowth was seen by week 2. Closure of the Medpor obturated defects occurred more rapidly than in the silicone group. The Medpor implants and calvarial bone demonstrated bone and soft-tissue fixation, callus formation and maturation, while mature overlying mucosa was reconstituted over the defects. Silicone implants demonstrated a fibrous tissue reaction within 1 week of implantation and they never became fixed to bone or soft tissue. Maxillary sinus wall regeneration occurred in all defects. This study supports clinical observations of maxillary sinus wall regeneration in humans.

The case was described of a 43 year old male who developed burns of the both shins as a result of handling wet cement. After wet cement was spilled into the rubber boots he was wearing, he experienced painful erythema of both lower legs. Several weeks later, medical examination revealed dirty and granulated ulceration of the both shins. The largest ulcer, about 18 by 10 centimeters, was located on the anterior aspect of left lower leg. We coneluded that this skin problem resulted from the ertreme alkalinity of calcium hydroxide in wet cement, combined with the effects of pressure and occlusion against the skin.

PURPOSE: We have investigated the long term effect, stability, predictability and complication of ICL implantation to treat high myopia. METHODS: We investigated retrospectively in 176 eyes of 97 patients with spherical equivalent -11.91D (-6D~-23D) that were followed up for at least 6 months after ICL implantation. RESULTS: Mean spherical equivalent was maintained stable as -0.54D at 1 week post-operatively, and at -0.55D for 5years. There was high effect and predictability, with 92.3% of the eyes exhibiting a greater than or equal to best corrected visual acuity (BCVA), 83% of eyes having a post-operative uncorrected visual acuity (UCVA) of 0.5 or better, 91.3% having a post-operative refraction of -1.0D~+1.0D, and 86.4% having a post-operative refraction of -0.5D~+0.5D. The most common complications were glare and halos. With a temporary increase in IOP, significant endothelial cell loss was observed. Repositioning for a dislocated ICL was done in 3 eyes. Post-operative cataracts were found in 7 eyes (3.9%), which was a significant increase in incidence, but not surprising, as the patients were older and had lower Vaulting values. CONCLUSIONS: ICL implantation to treat high myopia was an effective surgery with good predictability and stability, and effective in both short term and long term follow-up periods.
