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.

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.

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.

Many guidelines for hepatocellular carcinoma (HCC) have been published and are regularly updated worldwide. HCC management involves a broad range of treatment options and requires multidisciplinary care, resulting in significant heterogeneity in management practices across international communities. To support standardized care for HCC, we systematically appraised 13 globally recognized guidelines and expert consensus statements, including five from Asia, four from Europe, and four from the United States. These guidelines share similarities but reveal notable discrepancies in surveillance strategies, treatment allocation, and other recommendations. Geographic differences in tumor biology (e.g., prevalence of viral hepatitis, alcohol-related liver disease, or metabolic dysfunction-associated steatotic liver disease) and disparities in available medical resources (e.g., organ availability, healthcare infrastructure, and treatment accessibility) complicate the creation of universally applicable guidelines. Previously, significant gaps existed between Asian and Western guidelines, particularly regarding treatment strategies. However, these differences have diminished over the years. Presently, variations are often more attributable to publication dates than to regional differences. Nonetheless, Asia-Pacific experts continue to diverge from the Barcelona Clinic Liver Cancer system, particularly with respect to surgical resection and locoregional therapies, which are viewed as overly conservative in Western guidelines. Advancements in systemic therapies have prompted ongoing updates to these guidelines. Given that each set of guidelines reflects distinct regional characteristics, strengths, and limitations, fostering collaboration and mutual complementarity is essential for addressing discrepancies and advancing global HCC care.
