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.

PURPOSE: To determine the clinical efficacy of percutaneous vertebroplasty in cases of painful and medically intractable osteoporotic vertebral compression fracture. MATERIALS AND METHODS: Ninety-eight patients (20 men and 78 women; mean age, 69 years) underwent 122 per-cutaneous vertebroplasty procedures for the treatment of osteoporotic vertical compression fracture. For the evaluation of bone mass, bone densitometry was performed in 45 patients, and to assess the recent evolution of the fracture, all 98 underwent MRI. Percutaneous vertebroplasty involves percutaneous transpedicular puncture of the involved vertebrae followed by the injection of a Polymethylmethacrylate(PMMA)-Barium mixture into the vertebral body. To assess leakage of the mixture into the epidural tissue, neural foramina, venous plexus and paravertebral tissue, we then immediately obtained a computerized tomographic (CT) scan, assessing the clinical efficacy of the procedure on the basis of time required for pain relief (defined as more than 60% reduction of initial pain), and time required for ambulation without significant pain. RESULTS: Percutaneous vertebroplasty was successful in all patients. Pain relief was accomplished within 1-5(mean, 1.8) days and early ambulation without significant pain was possible within 2 -15 (mean, 3.3) days. Post-procedural CT scanning revealed leakage of the PMMA-barium mixture into Paravertebral tissue(n=41), the paravertebral venous plexus (n=34) and epidural tissue (n=4). No neural foraminal leakage was identified, and no procedure-related complication requiring surgical treatment occurred. CONCLUSION: Percutaneous vertebroplasty is an effective new interventional procedure for the treatment of osteoporotic vertebral compression fracture. It relieves pain, provides early mobilization, and strengthens involved vertebral bodies.

Intussusception is the most common cause of intestinal obstruction in early childhood and characterized by periodic colicky abdominal pain or irritability, vomiting, current jelly stool, and sausage-like abdominal mass. Meckel's diverticulum is common intestinal anomaly presenting with painless rectal bleeding during first 2 year of age. It is recognized as a common leading point of intussusception in childhood. Hematemesis is the rare clinical manifestation of both intussusception and Meckel's diverticulum. A 7-year-old girl presented with hematemesis was diagnosed as having intussusception by abdominal ultrasonography. Meckel's diverticulum was the leading point of intussusception in this case.

Adrenal cysts are a rare disease, and its prevalence is reported to be 0.06~0.18%. Its frequency of being recognized is increasing due to the widespread use of ultrasonography and computed tomography (CT) scans. We report here on a case of adrenal cyst that was mistaken as biliary cystadenoma prio-ocation and features. Laparoscopic exploration was performed via the transabdominal approach and this revealed a right adrenal cystic mass in the retroperitoneum beneath the liver (segment IV). We present here a case of adrenal cyst with endothelial lining along with a review of the literature to address the clinical presentation, histology, imaging features and differential diagnosis of this interesting and rare entity.
