BACKGROUND: The loss of ganglion cells observed in Alzheimer's disease (AD) patients might be attributable to a neurodegenerative process involving the neuroretinal structure. The objective of this study was to determine the retinal thickness in patients with AD using optical coherence tomography (OCT). METHODS: Neuro-ophthalmologic examinations were performed in eight AD patients and eight age-matched control subjects. The average thicknesses of the retinal nerve fiber layer (RNFL) and the ganglion cell-inner plexiform layer (GCIPL) were measured using spectral-domain OCT in both subject groups, and the results were compared. RESULTS: The RNFL was thinner in AD patients than in the age-matched controls (p<0.05), especially at the nasal and inferior retina, and the GCIPL was also significantly thinner (p<0.05). CONCLUSIONS: The decreased retinal thickness observed in AD patients suggests that OCT can be used as a biological marker of AD. The findings of this preliminary study suggest that the extent of the reduction in GCIPL and RNFL thicknesses should be investigated further.

Lymphoma of the prostate is exceedingly rare. Much more common than primary lymphoma of the prostate id secondary involvement of malignant lymphomas originating at other sites. A variety of treatments have bee n used, including prostatectomy, radiotherapy or combinations of chemotherapy and radiotherapy. Generally, the prognosis is very poor, and there is currently no consensus regarding treatment. We report on a patient with T-cell lymphoma who presented with symptoms of bladder neck obstruction. The patient has been asymptomatic and under complete remission after completion of doxorubicin-based chemotherapy for 2 cycles.

The growth changes in position of upper and lower jaws, incisal inclination in relation to anterior cranial base have been described. Twenty five males was studied quantitavely by means of serial cephalometric reontgenogram from seven to thirteen years of age. The findings seem to warrant the following conclusions: 1. Growth change in anteropaterior of upper and lower jaws to the anterior cranial base showed very littel change before eleven years of age but axial inclination of incisal teeth tended to become labiaization in relation to the anterior cranial base. 2. After eleven years of age, there wasn¥t nearly labialization of incisal teeth but jaw prognathism occurred a little in relation to the anterior cranial base.

OBJECTIVES: Aim of this study is to investigate the clinical efficacy of the vestibular function tests (VFTs) and the predictability of lesion side of vestibular asymmetry parameters in acute unilateral peripheral vestibulopathy. METHODS: Medical records and results of VFTs (caloric, rotatory chair, and head impulse tests) of 57 patients with acute unilateral vestibulopathy were reviewed retrospectively. The VFTs were examined within 7 days after the clinical onset. RESULTS: For the caloric test, 74% showed significant canal paresis and the predictability of lesion side was 88%. For the sinusoidal harmonic acceleration test, 91% had low gain in at least 1 Hz, phase lead showed 70%, 89% showed phase asymmetry and the predictability of lesion side was 90%. For velocity step test, 67% had abnormal Tc asymmetry and the predictability of lesion side was 95%. In bedside head impulse test (HIT), abnormal catch up saccades were observed in 89% and the predictability of lesion side was 100%. For the video HIT, cover or overt catch-up saccades were observed in 95% and the predictability of lesion side was 100%. One hundred percent (100%) had low gain on the video HIT, but the lesion sides were uncertain because of bilateral involvements or artifacts. CONCLUSIONS: The most important things in the diagnosis of acute unilateral vestibulopathy are typical clinical symptoms and spontaneous nystagmus. A combination of rotatory, caloric, and HITs will result in a more complete examination of the vestibular system. Among them, HIT is recommended as the best tool in acute unilateral vestibulopathy.

PURPOSE: To determine the accuracy of predicting potential visual acuity in cataract using the illuminated near card (INC). METHODS: Thirty-nine eyes (34 patients) having cataract were studied prospectively by comparing the postoperative distance Snellen acuity to the visual acuity (VA) obtained preoperatively using the INC viewed through a pinhole. RESULTS: The INC predicted postoperative acuity within two Snellen lines in 20 of 39. The accuracy between predicted and achieved acuities was follows: 61.5% in patients with a preoperative acuity of better than 0.3, 53.8% of better than 0.1, 50.0% of better than 0.05 and 28.6% of worse than 0.05. The disparity between INC results and postoperative VA was 3.89 lines (cortical opacity, nucleosclerosis, subcapsular opacity), 2.48 lines (cortical and subcapsular opacity), 2.08 lines (cortical opacity, nucleosclerosis), 1.8 lines (nucleosclerosis only), 3.3 lines (nucleosclerosis, subcapsular opacity), 1.6 lines (subcapsular opacity) and 3.0 lines (the others). CONCLUSIONS: The INC is easy to use and is a fast and accurate measurement instrument for predicting postoperative VA after cataract operation.

PURPOSE: The purpose of this study was to explore the utility of autism spectrum disorder (ASD) screening tools using community network of home childcare center visiting nurses. METHODS: The design of this study is multilevel survey to find the ASD using modified checklist for autism in toddlers (M-CHAT) for first screening by childcare teachers, checklist for autism in toddlers (CHAT) for secondary screening by nurses, Autism diagnostic observation schedule (ADOS) and Autism diagnostic interview revised (ADI-R) for final diagnosis by pediatric psychiatrists. RESULTS: In first screening by using M-CHAT, 61 subjects(0.56%) were detected among 8,926 subjects. Among the first screened 61 subjects, 13 subjects were exempted for normal finding in CHAT. 24 subjects consented participation for final diagnosis and 23 of them were diagnosed ASD. CONCLUSION: In conclusion, M-CHAT and CHAT were verified their utility as screening tools for ASD in the community and the community health networks as a childcare visiting nurses can be useful network in early detection and referral of ASD.

BACKGROUND: Recently, a lower incidence of late potentials has been reported in patients with acute myocardial infarction after successful thrombolysis when compared with conventionally treated patients. In another recent study, however, no significant effect of thrombolytic therapy on any abnormal signal average electrocardiography was found at 13 days after acute myocardial infarction. The present study was designed to determine the prognostic significance of the signal average electrocardiography and to evaluate the possible value of this technique as a noninvasive tool for monitoring of coronary occlusion and reperfusion. METHODS: Signal averaging was performed by using a signal average electrocardiography with bidirectional filterings before coronary artery occlusion, at 5 minutes after coronary occlusion and on reperfusion in 20 cats. Three of them died due to malignant ventricular arrhythmia during reperfusion. In all cats, approximately 250 beats were averaged. All data were analysed at filter frequency 25 to 250Hz, 40 to 250Hz and 80 to 250Hz. The following quantitative high resolutional electrocardiographic variables were calculated by computer : 1) filtered total QRS duration, 2) duration of HFLA(high frequency low amplitude) signals under 40uV, 3) RMS voltage of terminal 40ms, 4) mean Voltage of terminal 40ms, 5) average noise voltage. RESULTS: At the filter frequency of 40 to 250Hz and 80 to 250Hz, the filtered QRS duration and duration of HFLA signals 40uV were significantly prolonged at 5 minutes after coronary artery occlusion than before coronary occlusion(p<0.01). At the filter frequency of 40 to 250Hz and 80 to 250Hz, the RMS voltage(terminal 40ms) and mean voltage(terminal 40ms) were significantly prolonged at 5 minutes after coronary artery occlusion than before coronary occlusion(p<0.01, p<0.01 respectively). At the filter frequency of 80 to 250Hz, the filtered QRS duration and at the filter frequency of 25-250Hz, the duration of HFLA signals at 40uV were significantly shortened during reperfusion than at 5 minutes after coronary artery occlusion(p<0.01, p<0.05 respectively). At the filter frequency of 40 to 250Hz and 80 to 250Hz, the RMS voltage(terminal 40ms) and mean Voltage(terminal 40ms) were significantly shortened during reperfusion than at 5 minutes after coronary artery occlusion(p<0.01, p<0.01 respectively). There was no significant change of the filtered QRS duration, duration of HFLA signals 40uV,RMS voltage(terminal 40ms) and mean Voltage(terminal 40ms) after reperfusion compared with those of control at the filter frequency of 25 to 250Hz, 40 to 250Hz and 80 to 250Hz respectively. CONCLUSION: These results suggest that the signal average electrocardiography could be a valuable tool for monitoring the state of coronary artery occlusion and reperfusion.

PURPOSE: To investigate ocular complications that occur after orbital preservation surgery for paranasal malignancies and to identify the early clinical features of ophthalmic manifestations in paranasal malignancy patients. METHODS: We reviewed the clinical charts of patients following ophthalmic consultation after orbital preservation surgery for paranasal malignancies. We also investigated the early clinical features of ophthalmic manifestations in patients with paranasal malignancies. RESULTS: In our study, 54 patients had paranasal malignancies. Among them, 41 had undergone orbital preservation surgery, and 19 patients sought an ophthalmology consultation. There were seven patients who presented with eye symptoms caused by paranasal malignancies before the diagnosis. Paranasal malignancies included squamouscell carcinoma (13 cases), adenocarcinoma (3 cases), plasmocytoma (1 case), malignant schwannoma (1 case), and undifferentiated carcinoma (1 case). The locations of the origin of the tumor included the maxillary sinus (16 cases) and the ethmoid sinus (3 cases). The most common eye symptoms after orbital preservation surgery were enophthalmos, lid retraction, tearing, strabismus, inflammation, dry eyes, and cataracts, in order of frequency. Patients who visited the ophthalmic clinic due to paranasal malignancies had eye symptoms such as proptosis, nonspecific ocular pain, strabismus, tearing, eyelid swelling, and relative afferent pupillary defects, in order of frequency. CONCLUSIONS: Ocular complications were more common if the paranasal malignancy had invaded the orbital bone. However, many of the patients with disease invasion of the periosteum had no nasal or ocular symptoms upon presentation. Therefore, these patients should be managed carefully since symptoms may initially be vague and nonspecific.
