Extrahepatic metastasis of Hepatocellular carcinoma(HCC) to the gastrointestinal tract is uncommon. Because most of metastases to the gastrointestinal tract have no clinical manifestations, they are usually found incidentally at the time of an autopsy or a laparotomy, We experienced a case of duodenal metastasis of HCC, which presented UGI bleeding. A 59 years old male was admitted to our hospital due to generalized jaundice, which lasted for about a week. From the third day of admission, he had episodes of hematemesis and melena. An abdoinal CT scan demonstrated multiple, variable sized low-density masses in the entire liver with portal vein thrombosis and conglomerated lymph nodes. An esophagogastroduodenoscopy showed a protruded submucosal mass-like lesion with multiple ulceration in the duodenal bulb. We confirmed the duodenal mass-like lesion to be hepatocellular carcinoma by a biopsy and a histoimmunochemical study.

PURPOSE: The purpose of this study was to determine the efficacy of sonography in the evaluation of normal pseudocapsular morphology and the detection of complications after total hip arthroplasty. MATERIALS AND METHODS: Between Janvary 1997 and June 2000, 47 patients [35 men and 12 women aged 24 to 84 (mean, 61) years] using real-time linear-array, convex US units with 3.5-MHz and 10-MHz transducers. Normal capsular morphology in 30 with total hip replacements, who had been asymptomatic for at least one year, was studied, and the prosthetic joint infection demonstrated in six of 17 who had experienced was confirmed at surgery or by US-guided aspiration. RESULTS: Sonograms indicated that a normal pseudocapsule lay straight over the neck of the prosthesis or was slightly convex toward the neck, and that the mean bone-to-pseudocapsule distance was 2.9 mm. However, in the 11 symptomatic patients in whom no evidence of infection was revealed by cultures, th mean distance was 4.7 mm; in the remaining six patients, whose joints were infected (a condition strongly suggested by the presence of extracapsular fluid), the mean distance was 5.5 mm, with no significant difference between the two groups. CONCLUSION: Sonography can be used to evaluate normal caspular morphology after total hip replacement and to diagnose infection around hip prostheses. In all patients in whom sonography revealed the presence of extra-articular fiuid, infection had occurred.

BACKGROUND: Group B streptococcus (Streptococcus agalactiae, GBS) was reported as a major cause of neonatal infection and death. To prevent vertical transmission, CDC recommended that all women in week 35-37 of pregnancy should receive the GBS colonization test. We conducted a systematic review and meta-analysis to evaluate diagnostic accuracy and detection rate of real-time PCR for GBS in pregnant women. METHODS: The literature review for GBS using real-time PCR was done including KoreaMed, Ovid-MEDLINE, Ovid-EMBASE, and Cochrane Library on November 3, 2015. 443 articles were collected. Two authors select articles and evaluated the quality of studies using Scottish Intercollegiate Guidelines Network tool independently. RESULTS: Diagnostic accuracy of the real-time PCR was assessed by meta-analysis through 34 articles (13,516 for real-time PCR, 1,815 for culture and other comparison test). The GBS colonization was assessed through 34 articles, which reported varying values of 2.0–69.2% using real-time PCR. The real-time PCR for GBS was shown to have overall sensitivity of 0.93 (95% CI 0.92–0.94, I2=86.3%), overall specificity of 0.96 (95% CI 0.96–0.96, I2=90.2%), SROC AUC of 0.99. CONCLUSION: Real-time PCR is an effective test for detecting GBS colonization in pregnant women, resulted in preventing the infection in a new born baby.

OBJECTIVE: Because of the limited penetration into the central nervous system after systemic administration of numerous therapeutic compounds, intratumoral chemotherapy for brain tumors has also been used. However, the efficacy of intratumoral drug administration is restricted by the poor diffusion of drug through tumor and brain interstitium. In order to enhance the diffusion of chemotherapeutic agent and increase the cytotoxicity with minimal dose, the authors report the results of convection-enhanced delivery(CED) of chemotherapeutic agent to the malignant brain tumor as a method of enhancing cerebral drug delivery. METHODS: Authors used "CADD-Micro(R) ambulatory infusion pump" from Deltec, which can be programmed for continuous infusion. Intratumoral injection of chemotherapeutic drug using the pump was applied to eight patients with glioma and one patient with lymphoma. Surgery was done and tumor was removed as much as possible. The tip of catheter was placed in the center of tumor cavity. Adriamycin (0.16~0.32mg) was put in the reservoir which was connected to the proximal catheter and fixed in the pump device. Twenty-four hours after surgery, Adriamycin was infused. RESULTS: There was no adverse reaction of CED technique. Compared with current delivery techniques, the improvement of survival rate has been observed(5 patients: alive, 3 patients: dead, 1 patient: lost(alive to 5 mo.)). CONCLUSION: CED can be useful method for distributing therapeutic molecules in the interstitial space of tumor and can be utilized for chemotherapeutic agents, immunotoxins, and gene etc..

Craniopharyngiomas exhibit benign histologic features. However, such tumors have a relatively high incidence of recurrence after surgical removal, In order to device reliable and efficient methods in identifying craniopharyngiomas with increased risk for recurrence after surgical removal, proliferating cell nuclear antigen(PCNA) expressions as well as histological characteristics of the tumor were analyzed. There were 43 patients who had been surgically confirmed and had paraffin-embedded tissue from June, 1984 to May, 1993 available for analysis from our department. Of the 43 patients, eighteen cases were in children(age of 15 years of less) and 25 cases were in adults. The mean follow-up period was 42.7 months. The histologic types were adamantinomatous in 30 cases, squamous papillary in 9 cases and mixed in 4 cases. There was no case of tumor recurrence in the squamous papillary group, while the recurrence rate was about 55% in the adamantinous group after surgical removal alone. The mean age of the admantinous group was younger than that of the squamous papillary group(17.5 vs. 37.9 years old. p=0.0012), and the squamous papillary type was found only in adults(age over 20). In the group of 30 patients treated by surgical removal without radiation, the PCNA labelling index, calculated by counting the basal cell layer only, was significantly higher in the group with recurrence than without recurrence(9.51 vs. 6.58. p=0.001). However, the PCNA labelling index obtained by counting all cells in the four high-power(x400) fields failed to demonstrate any correlation with tumor recurrence. With a reference value of 8, PCNA index of the basal cell layer demonstrated the predictive sensitivity of 81.8% and specificity of 84.2% for tumor recurrence. There was no significant difference in PCNA labelling indices between adamantinous and squamous papillary types. As PCNA labelling index of the basal cell layer, as well as the histologic type, are sensitive indicators for prediction of tumor recurrence after surgical removal of craniopharyngiomas, therefore they should be considered as an index for biologic behavior of the tumor.

Neurocutaneous melanosis is a rare congenital phacomatosis, characterized by the presence of multiple pigmented skin nevi at birth. Meningeal melanosis tending to become malignant and seizure. Dandy-Walker syndrome is a developmental disorder of brain characterized by cystic dilatation of the fourth ventricle and agenesis or hypoplasia of the cerebellar vermis. We studied a case of Dandy-Walker syndrome with neurocutaneous giant melanosis in a 3 years old boy.

Intradural lipomas not associated with spinal dysraphism are rare tumors of the spinal canal. The clinical course of most of the patients with intradural lipoma is slowly progressive with increasing leg weakness and gait disturbance during the first 5 years of life or early adulthood. Since neurologic deficits usually occur very slowly and insidiously, symptoms are present over 2 years in the majority of patients before a diagnosis is made. In view of such a clinical course, a huge intradural lipoma presenting with no neurological deficits in an adult is a very rare case. We present our recent experience with a case of a huge intradural lipoma of the cervical cord without any association with spinal dysraphism and other anomalies of the spine in a neurologically intact adult patient. A review of the literature is also discussed.

Acute necrotizing encephalopathy predominantly affects young children and infants living in Japan and Taiwan, and is characterised by acute encephalopathy with seizures and decreased level of consciousness. The Hallmark of the disease is diffuse and symmetrical CNS lesions of both thalami, brainstem tegmentum, cerebral periventricular white matter and cerebellar medula. The clinical, radiological and pathological features of this disease, a disease entity established recently, is proposed by Masashi Mizuguchi et al in 1995. The aetiology is unknown but infectious or parainfectious process seems likely. The diagnosis can be made without difficulty on the basis of the combination of a typical clinical figures and characteristic radiologic findings. There is no specific therapy or prevention. The prognosis was poor in the 1980s but has improved recently. We experienced a case of 6-month-old female infant with acute necrotizing encephalopathy and a thalamic hemorrhage. We report this case with a review of the related literatures.
