Kawasaki disease (KD) is an immune-mediated disease which is a leading cause of acquired cardiovascular disease in developed country. Recently, tumor necrosis factor-alpha (TNF-alpha) blocker, infliximab has been considered a promising option for patients with refractory KD. Although chronic use of a TNF-alpha blocker could increase risk of opportunistic infections, a few studies have documented that use of infliximab was safe without serious adverse effects in patients with KD. We observed serious bacterial infection after infliximab treatment in an infant with refractory KD. Our patient was a 5-month-old male infant diagnosed with KD who did not respond to repeated doses of intravenous immunoglobulin. We effectively treated him with a single infusion of infliximab (5 mg/kg), but gram-negative (Acinetobacter lwoffii) septicemia developed after infliximab infusion. Therefore, we report a case of serious septicemia after treatment with infliximab, and suggest considering the risk of severe infection when deciding whether to prescribe infliximab to an infant with refractory KD.

OBJECTIVE: To compare the visibility and procedural parameters between a standard spinal needle and a new laser-etched needle (LEN) in real-time ultrasonography guided lumbar medial branch access in a phantom of the lumbosacral spine. METHODS: We conducted a prospective single-blinded observational study at a rehabilitation medicine center. A new model of LEN was manufactured with a standard 22-gauge spinal needle and a laser etching machine. Thirty-two inexperienced polyclinic medical students performed ultrasonography-guided lumbar medial branch access using both a standard spinal needle and a LEN with scanning protocol. The outcomes included needle visibility score, needle elapsed time, first-pass success rate, and number of needle sticks. RESULTS: The LEN received significantly better visibility scores and shorter needle elapsed time compared to the standard spinal needle. First-pass success rate and the number of needle sticks were not significantly different between needles. CONCLUSION: A new LEN is expected to offer better visibility and enable inexperienced users to perform an ultrasonography-guided lumbar medial branch block more quickly. However, further study of variables may be necessary for clinical application.

Association of the hepatoid and choriocarcinomatous components in adenocarcinoma of the stomach is extremely unusual and raises a possibility of new approach understand the histogenesis of gastric hepatoid adenocarcinoma. This paper describes a Borrmann type III adenocarcinoma of the stomach with both choriocarcinomatous and hepatoid components in composite tumor pattern in a 50-year-old man. Tubular arrangement of differentiated embryonalcarcinoma was encountered in choricarcinomatous and hepatoid areas, which showed strong immunoreactivity to beta-HCG and AFP, respectively. The findings suggest that gastric adenocarcinoma may have a potential of differentiation toward embryonal carcinoma. from which both choriocarcinoma and hepatoid variant of gastric adenocarcinoma may develop by retrodifferentiation.

PURPOSE: To investigate the characteristics of the limbal epithelial cells auto-cultivated in vivo on amniotic membrane (LIVAMs) designed for the treatment of limbal stem cell deficiency. METHODS: We removed the epithelium of AM with a No.15 blade after it was blotted with 20% ethanol and made a 360 degrees stromal flap along the epithelial defect. We then mounted over-sized AM (1 mm larger in diameter than the defect) over the defect with the border of AM inserted under the flap, and performed interrupted suture with 10-0 nylon. A therapeutic contact lens was fitted over the AM and a temporary tarsorrhaphy was performed. To examine whether the limbal epithelial cells grew well onto AM, we observed the cornea after fluorescein dye staining using a slit lamp. To explore the characteristics of LIVAMs, we performed hematoxylin-eosin (H&E) staining, immunochemical staining with AK-2, AE-5, AM-3 monoclonal antibodies, and transmission electron microscopy. RESULTS: Three of four rabbits had successful epithelial growth on the amniotic membrane. The epithelial growth on the amniotic membrane was stained using immunohistochemical staining (AK-2, AE-5). Electron microscopy showed a structure similar to that of a normal corneal epithelium. CONCLUSIONS: The technique of auto-cultivation of limbal epithelial cells in vivo on amniotic membrane can be an efficient and convenient method and preserves the characteristics of limbal epithelial cells for the treatment of limbal stem cell deficiency.

Congenital absence of the gall bladder without extrahepatic biliary atresia is an extremely rare congenital malformation with a reported incidence ranging between 0.01 and 0.02%. It is thought to be occurred from failure of the gallbladder bud to develop in utero and frequent association with other malformations. Agenesis can be randomly discovered at autopsy or operations for symptoms suggestive of biliary tract disease. The authors report a case of agenesis of the gallbladder without extrahepatic biliary atresia in a neonate which was incidentally found at laparotomy for presumed duodenal obstruction, with a review of the literature.

Spontaneous gastric perforation of the newborn is a rare, serious and life-threatening problem. This is surgical emergency because of high mortality. Most historical reports have described gastric perforation in the neonate as spontaneous cause. But, recent reviews report the contributing factor including prematurity and mechanical ventilation. Usually clinician identifies the pneumoperitoneum in simple abdomen X-ray. The final diagnostic method is surgical finding and the treatment of gastric perforation is immediate surgical correction. Early diagnosis, hemodynamic monitoring and fluid therapy for hypovolemia improve outcome. Pseudocyst formation after gastric perforation is very rare in newborn. We report a rare case of pseudocyst formation after spontaneous gastric perforation in full term newborn.
