PURPOSE: Prolonged fetal hypoxia stimulates erythropoiesis in fetal life and induces increased nucleated erythrocytes(NRBC) counts at the early newborn period. To evaluate the relationship between prolonged fetal hypoxia and neonatal intraventricular hemorrhage (IVH), and the prediction of neonatal IVH by neonatal NRBC. METHODS: We compared the daily courses of the absolute NRBC count in preterm new- boms at 34 weeks' gestation or earlier with(n=17) and without(n=20) IVH for 7 days of life. RESULTS: Absolute NRBC counts at birth were higher in neonates with IVH than in control neonates(2,499/mm3+/-3,748 and 412/mm3+/-272, respectively, P=0.0022). The cut-off value of 1,000/mm3 for absolute NRBC counts at birth showed the best parameter estimate of the predictive model for IVH at early newborn period with 100% of positive predictive value and 74.1% of negative predictive value. CONCLUSION: Prolonged fetal hypoxia inducing fetal erythropoiesis near labor is closely related to IVH at early newborn period. Thabsolute NRBC counts at birth is the very important predictable marker for the condition.

This case report demonstrates an unnecessary endodontic treatment of teeth with florid cemento-osseous dysplasia (FCOD) due to a misdiagnosis as periapical pathosis and emphasizes the importance of correct diagnosis to avoid unnecessary treatment. A 30-year-old woman was referred to our institution for apicoectomies of the mandibular left canine and both the lateral incisors. The periapical lesions associated with these teeth had failed to resolve after root canal treatment over a 3-year period. Radiographic examinations revealed multiple lesions on the right canine, the second premolar, and both first molars as well as the anterior region of the mandible. Based on clinical, radiographic and histological evaluations, the patient condition was diagnosed as FCOD. The patient has been monitored for 2 years. To avoid unnecessary invasive treatment, accurate diagnosis is essential before treatment is carried out in managing FCOD.

We experienced a case of primary hepatic actinomycosis which was initially diagnosed by means of fine needle aspiration. The patient was a 31-year-old emaciated man with a 2-month history of 10 kg weight loss, right upper quadrant pain and flank pain. The liver was palpable and tender on physical examination. Computerized tomography scan of the liver showed two ill-defined hypodense masses in gallbladder fossa and inferior pole of right lobe. Hepatocellular carcinoma was clinically suspected. A CT-guided fine needle aspiration was performed. Microscopically, smears showed numerous radiating clusters of filamentous bacteria with many neutrophils and monocytes in necrotic background. The symptoms were improved by incision and drainage and massive administration of penicillin.

We investigated the occurrence of color vision loss in 70 organic solvent mixtures exposed workers and in 47 controls. Color Vision was assessed with a color arrangement test designed to identify the defective color sense, the Han Double 15-Hue Test. The results of the test were no significant difference between exposed workers and controls in the proportion of subjects who committed one or two errors. Quantitative analysis, using color confusion index(CCI), showed no signifiant difference between exposed workers and controls. A significant linear correlation was present between age and CCI in both exposed workers(CCi=0.0056age + 0.94; r=0.23; p<0.05) and controls(CCI=0.0066age + 0.86; r=0.33; p<0.05). Qualitative analysis of the patterns on the hue circle showed that the prevalence of acquired dyschromatopsia was 21% in both and no significant difference. Multiple regression analyses showed that age was significantly related to color vision loss. These results did not provide evidence of a relationship between organic solvents exposure and incidence of color vision loss. In field studies for monitor the people at risk of the acquired color vision loss involving low-dose organic solvents exposed workers, both quantitative and qualitative information should be considered.

An 18-Year-old male hemophiliac with high titer of factorVIII inhibitor, stage V hemophilic arthropathy in right knee joint and a history of hematuria and retroperitoneal hemorrhage was admitted because of acute and massive bleeding of epistaxis, pulmonary hemorrhage and intestinal bleeding. The bleeing was not controolled by massive infusion of factorVIII concentrates but by prothrombin complex concentrates and high dose of factorVIII concentrates. He showned symptoms of sustained fever and diffuse pulmonary infiltration which was diagnosed as pulmonary hemosiderosis by MRI. We suppressed his immune reaction by prednisolne to prevent the formation of factorVIII inhibitor. He has been followed up for 3 years and shown no massive bleeding there-after.

BACKGROUND: Soil is one of the major habitats of fungi. Keratinophilic fungi are an important group of fungi that live in soil, some of which are potential pathogens for humans and animals. OBJECTIVE: The aim of this study was to isolate and identify keratinophilic fungi near Korean wrestling fields, playgrounds, and beauty salons. METHODS: We visited 5 Korean wrestling fields, 15 playgrounds, and 10 beauty salons in Daegu, Korea, from July to August 2015. Soil samples were divided into 3 groups according to the distance from Korean wrestling fields, playgrounds, and beauty salons: near, 10 m, and 100 m. RESULTS: Of 185 soil samples examined, 60 (32.4%) yielded keratinophilic fungi. Specifically, of the 125 samples around Korean wrestling fields and playgrounds, isolation rates were 37.7% (17/45) at the near distance, 27.5% (11/40) at 10 m, and 0% at 100 m. Of the 60 samples around beauty salons, isolation rates were 85% (17/20) at the near distance, 75% (15/20) at 10 m, and 0% at 100 m. Near Korean wrestling fields, playgrounds, and beauty salons, Penicillium spp. were the predominant species (16.9%, 11/65), followed by Fusarium spp. (13.8%, 9/65), Purpureocillium spp. (12.3%, 8/65), Microsporum spp. (6.1%, 4/65), Chrysosporium spp. (3.1%, 2/65), and other species. CONCLUSION: In this study, isolation rates of keratinophilic fungi were higher in the soil closer to the Korean wrestling fields, playgrounds, and beauty salons. Especially near beauty salons, we found keratinophilic fungi in most soil samples. We should be aware of these results and pay attention to eliminate hair or keratins in soils.

Keratosis*

Hydorxyapatite ocular implants, which are used to replace the volume of the orbit following enucleation and evisceration, allow the artificial eye to move. For this advantage, drilling is required to integrate peg into implant for transfer of motion. The earlier drilling, the earlier good results in cosmesis, but it should be done in the conditon of complete vascularization to reduce infection and exposure. To evaluate the proper timing for drilling and the difference of vascularization rate between standard eevisceration(group A) and modified evisceration(group B), we attempted to evaluate implant vascularization by using 99mTc-MDP bone scan prospectively at various intervals from 10 to 23 weeks(6 patients at 10-12 weeks, 29 patients at 13-16 weeks, 31 patients at 1720 weeks, and 7 patients as 21-23 weeks) after implantation. In 7 out of 73 patients postcontrast MRI was performed on the same day of 99mTc-MDP bone scan, we compared the degree of enhancement with that of uptake in each patients. In group A the ratio of complete graft vascularization was seen in 0% at 1012 weeks, 33% at 13-16 weeks, 50% at 17-20 weeks, and 67% at 21-23 weeks. On the other hadnd in group B it was seen in 50% at 10-12 weeks, 55% at 13-16 weeks, 55% at 17-20 weeks, and 75% at 21-23 weeks. It was increased with time. The time of complete vascularization was not different between group A and B. In 7 patients studied with both 99mTc-MDP bone scan and MRI, the degrees of vascularization were very similar on the two examinations in each patients. We would like to suggest that it is proper to perform 99mTc-MDP bone scan at 21 weeks after implantation regardless of surgical methods. 99mTc-MDP bone scan is more economic than postcontrast MRI for evaluation of complete vascularization in hydroxyaptite implant.
