Using Littmann's method for correcting the magnification of central fundus photographs, we evaluated the color photographs of 195 optic discs to measure the diameter and area of the optic disc. Minimal disc diameter ranged from 1.30mm to 2.53mm(mean 1.81mm) and maximal diameter from 1.53mm to 3.08mm(mean 2.04mm). Mean optic disc area measured 2.93mm2(minimum 1.63mm2, maximum 5.53mm2). The correlation coefficients between the refractive diopter of right eye and the disc diameter of right eye were 0.34 and between the refractive diopter of left eye and the disc diameter were 0.42. The correlation coefficients between the disc area and the refractive diopter were 0.43. There was no statistically significant difference in each optic disc diameter. Regarding the Gaussian distribution curve based on these preliminary data, microdiscs can be defined as being smaller than 1.57mm2(mean minus two standard deviations) and macrodiscs as being larger than 429mm2(mean plus two standard deviations).

BACKGROUND: Abdominal pain is one of the most common complaints in the emergency department and the evaluation presents an extraordinary challenge to the emergency physician's skill. C-reactive protein, an acute phase protein which is increased in the presence of inflammation in various clinical conditions, has been proven useful in assessing disease severity, in monitoring the development of complications, and in evaluating the response to specific treatments. So we tried to determine whether CRP offers an advantage over other clinical or laboratory variables for decision-making in the management of acute abdominal pain in the emergency department. METHOD: Patients who came to a University Hospital ED with acute abdominal pain, between september 1, 1998 and November 30, 1998, were included in this study, Data collection included age, sex, duration of symptom, location of pain, and laboratory dta(white blood cell count, portion of neutrophils, ESR, CRP, amylase). RESULT: This study included 85 patients, 34 of whom were men. The mean age was 36.9+/-19.1 years. CRP might be useful to detect the serious condition, sensitivity 81%, but more useful to differentiate normal condition from serious condition in acute abdominal pain patients, specificity 83%. CONCLUSION: CRP is an useful indicator of decision-making to abdominal patients in the emergency department. Hospitalization or operation is very unlikely when CRP value is normal.

A 9-year-old Korean boy with lissencephaly was found dead at home. He had previously been diagnosed with lissencephaly that presented with infantile spasm on the basis of magnetic resonance imaging and electroencephalogram results. Antemortem chromosomal banding revealed a normal karyotype. A legal autopsy was requested to eliminate the possibility of neglect or abuse by his parents. The autopsy findings revealed type I lissencephaly with the associated microcephaly. No external wounds or decubitus ulcers were noted. Postmortem fluorescence in situ hybridization for the LIS1 locus and nucleotide sequence analysis of the whole coding regions of the LIS1 gene did not reveal any deletions. The antemortem and postmortem findings revealed that lissencephaly syndrome was associated with isolated lissencephaly sequence. External causes of death were excluded by the full autopsy and toxicology test results. Because patients with mental retardation are frequently victimized and suffer neglect or abuse, thorough external and internal examinations should be conducted at the time of autopsy.

Squamous cell carcinoma (SCC) is a common head and neck cancer that is usually restricted to the mucosal surfaces and skin, so sometimes it is very difficult to diagnose a primary lesion. We report a case of a 73-year-old man who presented as a small skin ulcer and parotid mass. The pathologic diagnosis was a squamous cell carcinoma, although it was very difficult to distinguish between skin cancer invading the parotid gland and a primary SCC of the arotid gland extending to the skin. The patient was treated with surgical resection and radiation therapy.

Mucinous adenocarcinomas of the anal region constitute only 2% of anal cancer and adenocarcinoma developing in a chronic tuberculous anal fistula is extremely rare. In most cases, its origin is difficult to ascertain because the primary sites have already been destroyed before any diagnosis of malignancy is made. We experienced a case of perianal adcnocarcinoma developing in chronic tuberculous anal fistula, which was treated by abdominoperineal resection with preoperative chemo-irradiation. We reported a case and reviewed the related literatures.

PURPOSE: To evaluate clinical results of autologous osteochondral graft in osteochondral lesions of the talus. MATERIALS AND METHODS: Twenty feet in twenty patients underwent osteochondral autologous transfer in the osteochondral lesions of the talus. Sixteen were men and four were women. The mean age was 40.8 years old. The mean follow up was 2 years 9 months. Eighteen cases were medial, one case was lateral and one case was both, respectively. The average duration of symptom was 4 years 3 months. AOFAS ankle/hindfoot score (AOFAS score), visual analogue scale (VAS), Lysholm knee score were evaluated preoperatively and at the final follow up. RESULTS: Postoperative AOFAS score was 87.3 (range, 69-100), which was significantly improved from preoperative AOFAS score of 62.0 (p=0.000). Postoperative VAS was 2.9 (range, 0-7), which was significantly improved from preoperative VAS of 7.5 (p=0.000). Postoperative Lysholm knee score was 92.4 (range, 80-100). All osteotomy of medial malleolus was united by the 4th month after surgery. Postoperative VAS was conversely correlated with the follow up period (p=0.024). There was no complications associated with surgery. CONCLUSION: Autologous osteochondral grafts in osteochondral lesion of the talus demonstrated excellent results with a short-term follow up.

BACKGROUND AND PURPOSE: Cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most-common single gene disorder of cerebral small vessel disease. There is no definite evidence of genotype-phenotype correlation in CADASIL. However, recent studies have shown the unique phenotypic feature of NOTCH3 R544C mutation. METHODS: We investigated the phenotypic spectrum of NOTCH3 R544C mutation in 73 CADASIL patients in Jeju between April 2012 and January 2014. RESULTS: Of the 73 subjects from 60 unrelated families included in this study, 40 (55%) were men. The mean age of the subjects was 62.2±12.2 (range 34-86 years). Cerebral infarction was the most frequent manifestation (37%), followed by cognitive impairment (32%), headache (17%), psychiatric symptom (16%), intracerebral hemorrhage (12%), transient ischemic attack (7%), and seizure (1%). The mean age of the subjects with ischemic or hemorrhagic episodes was 64.9±10.9 (range 41-86 years). A diagnosis of dementia was made in 12 subjects (16%). The mean age of the subjects with dementia was 75.6±6.5 (range 62-86 years). About 3% of subjects were unable to walk without assistance at assessment. Only one subject had developed chronic headache before the 40s. CONCLUSIONS: Our data support the hypothesis that CADASIL patients with R544C mutation in Jeju have relatively late onset disease.

OBJECTIVE: Lumbar lordotic curve on L4 to S1 level is important in maintaining spinal sagittal alignment. Although there has been no definite report in lordotic value, loss of lumbar lordotic curve may lead to pathologic change especially in degenerative lumbar disease. This study examines the changes of lumbar lordotic curve after posterior lumbar interbody fusion with wedge shape cage. METHODS: We studied 45patients who had undergone posterior lumbar interbody fusion with wedge shape cage and screw fixation due to degenerative lumbar disease. Preoperative and postoperative lateral radiographs were taken and one independent observer measured the change of lordotic curve and height of intervertebral space where cages were placed. Segmental lordotic curve angle was measured by Cobb method. Height of intervertebral space was measured by averaging the sum of anterior, posterior, and midpoint interbody distance. Clinical outcome was assessed on Prolo scale at 1month of postoperative period. RESULTS: Nineteen paired wedge shape cages were placed on L4-5 level and 6 paired same cages were inserted on L5-S1 level. Among them, 18patients showed increased segmental lordotic curve angle. Mean increased segmental lordotic curve angle after placing the wedge shape cages was 1.96? Mean increased disc height was 3.21mm. No cases showed retropulsion of cage. The clinical success rate on Prolo's scale was 92.0%. CONCLUSION: Posterior lumbar interbody fusion with wedge shape cage provides increased lordotic curve, increased height of intervertebral space, and satisfactory clinical outcome in a short-term period.
