PURPOSE: Neonatal jaundice is one of the most common problems in our country leading to hospitalization. Agar is low cost, low risk, and easily fed orally; it can bind bilirubin in the intestine, decreasing its enterohepatic circulation, thereby decreasing serum bilirubin levels. At present, however, the effectiveness of agar in the prevention and treament of neonatal jaundice is quite conflicting and controversy. Recently we have read Caglayan's 'Superiority of Oral Agar and Phototherapy Combination in the Treatment of Neonatal Hyperbilirubinemia'. The result was very hopeful and attractive enough, and which gave us a motivation to study if it was really of value. METHODS: From May 1995 to April 1996, a total 50 term neonates admitted in nursery of Dong-Eui Medical Center with the capillary serum bilirubin levels greater than 10mg/ dl were enrolled in the study. Those with pathologic causes and breast fed infants were all excluded. The neonates were randomly devided into two groups; 25 of conventional phototherapy alone (P group) and 25 of oral agar plus conventional phototherapy combination (A+P group). The study was terminated when the capillary serum bilirubins were decreased to 8mg/dl. Pastagar B (Pasteur Institute 64946) 500mg in 10ml distilled water were fed four times a day using 10ml syringes prior to bottle feeding. Capillary serum bilirubin levels were measured daily at 10:00 a.m. with heel pad samples. Daily stool frequency and adverse effects of treatment were observed closely. RESULTS: 1) The decrement of the serum bilirubin levels at first 24 hours of therapy was significantly different between P and A+P groups showing as 1.7+/-1.2 and 2.4+/-1.0mg/dl respectively (p<0.05). 2) Mean time for bilirubin to decrease to 8mg/dl was shorter in A+P group than in P group showing as 45.7+/-20.8 and 57.5+/-32.3 hours each other, but those differences were statistically insignificant (p>0.05). 3) No adverse effects such as rashes or abdominal pains were observed during treatment. Differences of mean stool frequency were significant between P and A+P groups showing as 3.7+/-1.2 and 4.7+/-2.0 times per day respectively (p<0.05). CONCLUSION: The agar plus conventional phototherapy combination was superior to conventional phototherapy alone at first 24 hours of therapy in neonatal hyperbilirubinemia, but further more careful researches would be necessary for using it routinely in the treatment of neonatal hyperbilirubinemia in future.

BACKGROUND AND PURPOSE: Mutations of the skeletal muscle sodium channel gene SCN4A, which is located on chromosome 17q23-25, are associated with various neuromuscular disorders that are labeled collectively as skeletal muscle sodium channelopathy. These disorders include hyperkalemic periodic paralysis (HYPP), hypokalemic periodic paralysis, paramyotonia congenita (PMC), potassium-aggravated myotonia, and congenital myasthenic syndrome. This study analyzed the clinical and mutational spectra of skeletal muscle sodium channelopathy in Korean subjects. METHODS: Six unrelated Korean patients with periodic paralysis or nondystrophic myotonia associated with SCN4A mutations were included in the study. For the mutational analysis of SCN4A, we performed a full sequence analysis of the gene using the patients' DNA. We also analyzed the patients' clinical history, physical findings, laboratory tests, and responses to treatment. RESULTS: We identified four different mutations (one of which was novel) in all of the patients examined. The novel heterozygous missense mutation, p.R225W, was found in one patient with mild nonpainful myotonia. Our patients exhibited various clinical phenotypes: pure myotonia in four, and PMC in one, and HYPP in one. The four patients with pure myotonia were initially diagnosed as having myotonia congenita (MC), but a previous analysis revealed no CLCN1 mutation. CONCLUSIONS: Clinical differentiating between sodium-channel myotonia (SCM) and MC is not easy, and it is suggested that a mutational analysis of both SCN4A and CLCN1 is essential for the differential diagnosis of SCM and MC.

OBJECTIVE: The aim of this study was to evaluate the stress distribution and displacement of various craniofacial structures after nonsurgical rapid palatal expansion (RPE) with conventional (C-RPE), bone-borne (B-RPE), and miniscrew-assisted (MARPE) expanders for young adults using three-dimensional finite element analysis (3D FEA). METHODS: Conventional, bone-borne, and miniscrew-assisted palatal expanders were designed to simulate expansion in a 3D FE model created from a 20-year-old human dry skull. Stress distribution and the displacement pattern for each circumaxillary suture and anchor tooth were calculated. RESULTS: The results showed that C-RPE induced the greatest stress along the frontal process of the maxilla and around the anchor teeth, followed by the suture area, whereas B-RPE generated the greatest stress around the miniscrew, although the area was limited within the suture. Compared with the other appliances, MARPE caused relatively even stress distribution, decreased the stress on the buccal plate of the anchor teeth, and reduced tipping of the anchor teeth. CONCLUSIONS: The findings of this study suggest that the incorporation of miniscrews in RPE devices may contribute to force delivery to the sutures and a decrease in excessive stress on the buccal plate. Thus, MARPE may serve as an effective modality for the nonsurgical treatment of transverse maxillary deficiency in young adults.

Malignant neuroendocrine tumors have the histological features of malignant tumors, and localized invasion and distant metastasis can occur. After clinical presentation, patients with neuroendocrine tumors usually show rapid deterioration. The first case involved a patient who underwent treatment for poorly differentiated adenocarcinoma of the lung. A percutaneous liver biopsy was performed to look for diffuse infiltration of the tumor in the liver. As a result, the patient was diagnosed with large-cell neuroendocrine carcinoma of the lung with diffuse liver metastasis. The other two patients presented with liver masses. Liver biopsies revealed metastatic neuroendocrine tumors of the liver. In patients presenting with diffuse hepatic infiltration of a tumor, a neuroendocrine tumor should be considered in the diagnosis, and immunohistochemical staining and further studies should be performed to locate the origin of the tumor. We report three cases of neuroendocrine tumors with diffuse liver metastasis.

BACKGROUND: Clinical isolates of Escherichia coli were evaluated to determine the prevalence and genotypes of Ambler class A extended-spectrum beta -lactamases (ESBLs). METHODS: Clinical isolates of E. coli were collected from 12 hospitals from February through July, 2004. Antimicrobial susceptibility was tested by disk diffusion and agar dilution methods, and ESBLproduction was determined by double-disk synergy test. TEM, SHV, CTX-M, PER-1, VEB, IBC, GES, and TLA type ESBL genes were detected by PCR amplifications, and the PCR products were subjected to direct sequencing. RESULTS: The double-disk synergy test was positive in 90.9% (149 in 164) of the ceftazidime- or cefotaxime-resistant E. coli isolates. The most prevalent types of Ambler class A ESBLs in E. coliisolates were CTX-M-15 (n=53). CTX-M-14 (n=24), CTX-M-3 (n=9), CTX-M-9 (n=3), CTX-M-12 (n=3), SHV-2a (n=1), SHV-12 (n=5) and TEM-52 (n=3) were also found. CTX-M-12 ESBL had never been reported before in Korea. CONCLUSIONS: CTX-M type ESBL-producing E. coli isolates are spreading and CTX-M-12 is emerging in Korea.

Infected aneurysms are uncommon, frequently fatal lesions. "True" fungus-infected aneurysms are even rarer. Fungal infections have high morbidity and mortality. However, diagnosis is frequently difficult, since the symptoms are non-specific and standard diagnostic procedures are often insensitive. We experienced a patient with persistent fever and negative blood cultures. The patient was immunocompetent and had no risk factors, and was diagnosed with a fungus-infected aneurysm based on computed tomography and vascular surgery. The vascular tissue revealed some narrow-based budding yeast within the thrombus, suggesting Candida infection. Seventeen cases of infected aneurysm of the abdomen were reported in Korea from 1988 to 2007, although none were "true" fungus-infected aneurysms, making this the first fungus-infected aneurysm of the abdomen in Korea. Prompt diagnostic procedures and aggressive treatment modalities are necessary for patients with occult infection and negative blood cultures, regardless of their immunocompetence, because of the high morbidity and mortality of this condition.
