PURPOSE: Polyarteritis nodosa is a necrotizing vasculitis affecting medium and small sized arteries throughout the vascular system, including ocular tissues. We report a case of orbital polyarteritis nodosa complicated with retinal vasculitis and exophthalmos. METHODS: A 51-year-old woman complained of swelling and hard mass in periorbital region for 3 months. The left eye was anophthalmos after enucleation secondary to corneal infection. The patient has treated marginal ulcer of the cornea and keratomalacia. Posterior synechia and motility disturbance of lateral rectus muscle were also revealed. Fundus examination showed focal retinal hemorrhage, macular hard exudate, and soft exudate, which may mean retinal vasculitis. Both eyes gradually developed exophthalmos. Orbital CT scan revealed homogenous infiltration in the orbit, ethmoid bone, and nasal cavity and perforation of the nasal septum. The pathologic examination for the biopsy specimen from the orbital tissue demonstrated a nongranulomatous vasculitis, diagnosing the polyarteritis nodosa. RESULTS: The authors present ocular manifestations, including marginal corneal ulcer, keratomalacia, dysfunction of the extraocular muscles, posterior synechia, retinal hemorrhage, soft exudate, hard exdate in the macula, and exophthalmos, in this patient with the polyarteritis nodosa.

Retinoic acid plays an important role in embryogenesis, by regulating morphogenesis, cell proliferation, differentiation, and extracellular matrix production. Also retinoic acid is a potent teratogen and induces a variety of limb and craniofacial malformations including cleft palate, that is the most common congenital malformation. Fibroblast growth factor 2 (FGF2) and fibroblast growth factor receptor 2 (FGFR2) are an important role in the secondary induction for the epithelial-mesenchymal transformation during development. Mutations in them, produce a congenital malformation in the skeletal system and the craniofacial tissue. It was of interest to explore the hypothesis of an inhibitory effect exerted by retinoic acid on the cell proliferating activity and the expression of FGF2 and FGFR2 in the developing palate in vivo. In the present study, author observed the expression of PCNA as a marker for the cell proliferating activity, FGF2 and FGFR2 to compare with developmental stages and locations in normal and retinoic acid-induced cleft palate. Retinoic acid was administered orally at gestational day (GD) 10 to ICR mice. The pregnant mice were sacrificed on GD 12, 13, 14, 15 to obtain the fetuses. Scanning electron microscope and immunohistochemistry was performed. In the retinoic acid-treated fetuses, palatal shelves did not elevate and cleft palate was induced. On GD 12, 13 in the palatal mesenchyme of the retinoic acid treated-fetuses, expression of the PCNA decreased. On GD 12 in the palatal epithelium of the retinoic acid-treated fetuses, expression of FGFR2 decreased, but after GD 13, the patterns of expression of FGFR2 were not affected. On GD 12, 13 in the palatal epithelium and mesenchyme of the retinoic acid-treated fetuses, expression of FGF2 decreased dramatically, but after GD 14, it was similar to that in the normal fetal palate. These results suggest that retinoic acid inhibits the cell proliferating activity and the expression of FGF2, FGFR2 in the palatal mesenchyme on GD 12, 13, which is critical in the developing palate, and elevation of palatal shelves is delayed and impaired. Moreover, it seems that retinoic acid inhibits the epithelial-mesenchymal transformation of epithelium. Finally, cleft palate is induced.

PURPOSE: The purpose of this study was to evaluate the characteristics of patients who received primary androgen deprivation therapy (PADT) for clinically localized prostate cancer and the clinical efficacy of this treatment. MATERIALS AND METHODS: Between January 1998 and August 2007, patients who underwent PADT for clinically localized prostate adenocarcinoma were analyzed. The patients studied could not receive definitive therapy owing to old age or medical comorbidities. All patients' Gleason score, pretreatment prostate-specific antigen (PSA) value, time to PSA progression, and D'Amico's risk criteria were analyzed. RESULTS: A total of 72 patients were analyzed. The patients' mean age was 75.29 years (range, 57-92 years) and their median pretreatment PSA was 13.52 ng/ml (range, 1.27-74.82 ng/ml). The median follow-up duration was 39 months (range, 18-115 months). Thirteen patients (18.57%) had PSA progression after reaching a PSA nadir. The mean time to PSA progression was 14 months (range, 7-55 months). Among these 13 patients, 2 patients had low-risk prostate cancer and 11 patients had high-risk prostate cancer by D'Amico's risk criteria. Three of the 13 patients are now receiving chemotherapy, 2 patients died from cancer progression, 3 patients died of a non-cancer cause, and 5 patients are now being conservatively managed. Of the total 72 patients, 70.83% of the patients are still receiving PADT. A total of 11 patients died; however, only 2 deaths were caused by prostate cancer. CONCLUSIONS: In patients with localized prostate cancer who could not receive definitive therapy for several reasons, the cancer-caused death rate was very low, even in patients with PSA progression. PADT is an effective therapeutic option in patients with localized prostate cancer.

PURPOSE: To evaluate the changes in the leg length discrepancy in idiopathic hemihypertrophy as a function of time. MATERIALS AND METHODS: A lower extremity scannogram was performed on 33 patients (16 boys and 17 girls) who were clinically diagnosed with idiopathic hemihypertrophy from September, 1985 to December, 1996. The leg length discrepancy was compared every 6 months. The mean age of the patients on the first visit was 1.6 years (range, 1 to 5 years) and the average follow up period was 9.1 years (range, 8 to 15 years). RESULTS: Not all the discrepancies continued to increase at a constant rate with time. The developmental discrepancy patterns identified were classified as follows: type I, increasing pattern; type II, increasing-plateau pattern; type III, plateau pattern; type IV, increasing-decreasing pattern; type V, decreasing pattern. Twenty five patients (75%) had types I and II discrepancy patterns. CONCLUSION: A continual periodic follow up of the leg length is important in idiopathic hemihypertrophy patients because the developmental patterns of a discrepancy in the length of a lower extremity can vary.

BACKGROUND: Conventional visual assessment of coronary arteriogram is fraught with large interobserver variance and disagreement with pathologic findings. Thus quantitative coronary angiography had been recently developed to meet the requirement of more reproducible measurement of severity of coronary artery disease. This study was designed to evaluate the interobserver variability of quantitative coronary angiography and its usefulness in clinical application. METHODS: Three independent observers analysed coronary angiogram of 31 consecutive patients by visual assessment and quantitative measurement using computer based algorithm. RESULTS: 1) There was considerable disagreement between 3 observers in the identification of significant coronary stenosis. Complete agreement was achieved in only 29/61 (47%) coronary lesion and agreement of more than 2 observers in 41/61(67%) lesion. 2) In visual assessment, the largest interobserver variance was found in acute marginal artery and distal circumflex artery, whereas the least variance was observed in proximal right coronary artery. 3) The average interobserver variance was 13.1% in visual assessment, 14.9% in geometric analysis, and 10.5% in video densitometric analysis. There was no significant difference between these values. 4) Visual assessment was noted to overestimate the severity of stenotic lesion, by 5.6% compared to geometric analysis and by 11.8% compared to video-densitometric analysis. CONCLUSION: These findings suggest that identifying significant lesion is major source of interobserve variability in both visual and quantitative analysis of coronary arteriogram. In addition, suboptimal image quality was responsible for the inability of quantitative analysis to reduce the variance. These factors seem to be major limitation of quantitative coronary arterirogam.

Microinvasive carcinoma of the uterine cervix(FIGO stage IA) has been reported as highly curable disease even with conservative surgery such as conization and simple hysterectomy. Nevertheless, the surgical management for microinvasive carcinomas has been proposed varying from conservative surgery to radical hysterectomy with pelvic nodes dissection according to different diagnostic criterias for microinvasive carcinoma. We reviewed 512 patients who had been diagnosed as microinvasive carcinoma of the uterine cervix at the Department of Obstetrics and Gynecology, Samsung Cheil Hospital and Women's Healthcare Center from Jan. 1988 to Dec. 1995. Among them, 376 patients were included in this study satisfying guided criterias such as proper management and follow up more than at least one year, and they were analyzed retrospectively based on the clinicopathologic characteristics, pattern of surgical management and postoperative status.

Intramedullary spinal cord metastasis is rare, but is being encountered with increasing frequency with the availability of more sensitive imaging techniques. RI is the most sensitive of these techniques, though it cannot differentiate between intramedullary spinal cord metastasis and other cord pathologies. Occasionally, therefore, surgical biopsy is indicated though optimal treatment after diagnosis remains controversial. Radical resection, radiation and chemotherapy significantly prolong survival, but many patients survive less than one year. The authors have encountered two cases of intramedullary spinal cord metastasis of small cell carcinoma of the lung. These are reviewed, together with literature describing adequate evaluation and management.

PURPOSE: Epinephrine itself exhibits some cardiotoxicity. However, it rarely induces cardiomyopathy when used in standard doses during surgery for local hemostasis. This paper reports a rare case of stress-induced cardiomyopathy in a young woman after the local infiltration of epinephrine. METHODS: Corrective rhinoplasty was planned in a 20-year-old woman. Lidocaine mixed with epinephrine 1:100,000 was injected around the skin of the nose and nasal septum after inducing anesthesia, which resulted in sinus tachycardia and hypotension. Postoperative ECG showed a T wave inversion in the lead V2 and echocardiography revealed transient hypokinesia in the cardiac apex. Cardiac enzyme was mildly elevated. RESULTS: Symptoms and laboratory findings improved considerably, and the patient was discharged from hospital without complications on the sixth day after surgery. CONCLUSION: The prognosis of catecholamine-induced cardiomyopathy is generally favorable. However, it is important to be aware of the possible adverse effects of local epinephrine infiltration. This case highlights the need for caution when using epinephrine.

The perforation and subsequent panperitonitis as one of the complications of a Meckel diverticulum is a rare complication, especially in infants. Complication of Meckel diverticulum, preoperative and operative patient's mean age is about 5 years old. A 13-month-old male infant presented at our emergency room with currant jelly stool of about 24 hours duration. Intussusception or bacterial enteritis was initially suspected. Gastrointestinal ultrasonography showed no evidence of intussusception or appendicitis. On the 3rd hospital day, he suddenly showed high fever and irritability. Abdominal CT suggested intraperitoneal and retroperitoneal abscess with air collection due to possible bowel perforation. The final diagnosis of perforation of Meckel diverticulum was made by laparoscopy and biopsy. We report a very rare case with perforation of Meckel diverticulum in infant period.
