Pelioid hepatocellular carcinoma (HCC), a type of atypical HCC, is a rare histologic type of HCC. The radiologic findings of the pelioid HCC is differ from the typical type of HCC. To our knowledge, this case report is the second literature to show the enhancing features of a pelioid HCC on dynamic computed tomography (CT). Here we describe the dynamic CT findings in a case of surgically confirmed pelioid HCC.

BACKGROUND: This study investigated the effect of pneumoperitoneum on the recovery from intense neuromuscular blockade by rocuronium in healthy patients undergoing laparoscopic abdominal surgery. METHODS: Thirty adult patients undergoing laparoscopic abdominal surgery were studied. Anesthesia was induced with 1.5 mg/kg of propofol, 12 ug/kg of alfentanil and 0.6 mg/kg of rocuronium and maintained with 2 vol% of sevoflurane and 0.05-0.2 microg/kg/min remifentanil. The neuromuscular relaxation was monitored by Train-of-Four (TOF) and post-tetanic count (PTC). Additional rocuronium of 0.2 mg/kg was administered for deep neuromuscular blockade at 30 min after pneumoperitoneum. Before (PPpre) and 30 min after pneumoperitoneum (PPpost), PTC was measured at 6 min intervals. The relationship between PTC and the time interval to reappearance of T1 response was observed. RESULTS: The mean +/- SD of the intervals between the detection of 4 counts of the PTC and the first response to TOF stimulation was 13.0 +/- 1.1 min and 16.4 +/- 6.3 min PPpre and PPpost, respectively (P = 0.20). There were significant negative relationships between PTC observed and the time interval to reappearance of T1 response (adjusted R2 = 0.869, P < 0.001 for PPpre data, and adjusted R2 = 0.561, P < 0.001 for PPpost data). Comparing the difference of regression equation between PPpre and PPpost data using a parallelism test, there was no statistically significant difference (P = 0.193). CONCLUSIONS: This study showed that PP with intra-abdominal pressure at the level of 13-14 mmHg did not affect the recovery from intense neuromuscular blockade by rocuronium in healthy patients undergoing laparoscopic abdominal surgery.

Lymphangioleiomyomatosis (LAM) is a rare, progressive cystic lung disease, characterized by a proliferation of immature smooth muscle cell (LAM cell) in the airway, parenchyma, lymph nodes and pulmonary vessels. It mainly affects women in their reproductive years. It is clinically manifested by recurrent pneumothorax, progressive dyspnea on exertion and chylothorax; it can also ultimately lead to respiratory failure. However, no curative treatment for LAM is currently available. We report an anesthetic management for cesarean delivery in a parturient newly diagnosed with LAM.

OBJECTIVES: The aim of this study was to investigate brain activation during a Korean language-based 'theory of mind (TOM)' task and fMRI in Korean schizophrenic patients. METHODS: Fourteen Korean schizophrenic patients and 15 normal controls participated in this study. For all participants, several clinical states and psychosocial functions were evaluated. The subjects were then scanned while performing Korean language-based fMRI tasks. The tasks were comprised of conditions-first order false belief (TOM task), physical causality, and unrelated situations. Imaging data were analyzed using SPM2 software (uncorrected p<0.005, extent threshold kappa=10). RESULTS: 1) Compared with the control group, the patient group showed significantly poorer performance on the TOM task, and no significant correlation between TOM and empathic abilitiesy. 2) In the patient group, there were no significantly activated brain regions associated with the TOM task as compared to the physical causality task. With respect to between-group differences, the patient group showed significantly less activation of the left medial frontal region (primarily BA 8) and signifcantly different activation of the left precuneus (BA 7) associated with the TOM task. CONCLUSION: These results suggest that Korean schizophreniac patients show different brain activity associated with TOM functions, especially with respect to the Korean language-based first order false belief tasks.
