Angiomyolipoma arising from the liver is a rare primary benign lipomatous tumor of the lever. We experienced a case of surgically proven hepatic angiomyolipoma, which was preoperatively diagnosed by definning of its characteristic histologic components and benign radiologic nature with various imaging modalities including ultrasound, dynamic computed tomography, angiography, and magnetic resonance imaging. It was the first reported case in the world that full radiologic evaluation was taken and internal vascular proliferation was defined by using dynamic bolus CT prior to angiography.

BACKGROUND: NCAM plays an important role in the peripheral innervation of the spinal neurons as well as in the development of the CNS. Although expression of NCAM is down-regulated in most areas of adult brain and spinal cord, it could be reexpressed after neuronal damages induced by various physical or chemical insults including peripheral nerve transection. METHOD: To investigate alterations of the NCAM immunoreactivity in the dorsal and ventral horns of the spinal cord induced by peripheral neurotomy and reconnection, the unilateral sciatic nerve of the rats were transected and immediately reconnected. Experimental animals were sacrificed at 1 week and 3 weeks after operation, and the alteration of NCAM immunoreactivity in the ventral and the dorsal horns of the lower lumbar spinal cord were examined. RESULTS: NCAM-immunoreactive astrocytes in the ipsilateral dorsal horn was increased at 1 week after operation. Neurons with NCAM?immunoreactive membranes and processes were increased in ipsilateral dorsal horns, and in large motor neurons of ventral horns of both sides at 3 weeks after unilateral sciatic neurotomy and reconnection. CONCLUSIONS: It is consequently suggested that unilateral sciatic neurotomy and reconnection induce the increase of the NCAM-immunoreactive neurons and glial cells in the spinal cord, and increase of NCAM immunoreactivity in the spinal cord may reflect the neuronal damage and healing process induced by peripheral nerve injury.

Actinomycosis is a chronic suppurative and granulomatous disease caused by Actinomyces species, which normally colonize the mouth, colon, and vagina. Actinomycosis affects any organ and it is histologically characterized by sulfur granule. Most of abdominal actinomycosis develop following appendicitis, diverticulitis or perforated viscus. Abdominal actinomycosis is commonly misdiagnosed as other diseases of intestine because the clinical presentation is non-specific and the radiologic findings mimic tumor. We report a case of abdominal actinomycosis, which initially presented as hydronephrosis and finally diagnosed after laparotomy. Histological findings showed sulfur granules, chronic granulomatous inflammation, and acute inflammatory cells. In our knowledge, this is the first report in Korea of the abdominal actinomycosis associated with appendicitis and complicated with hydronephrosis.

Statin-induced rhabdomyolysis is a frequent complication in renal transplant recipients receiving cyclosporine, but incidences are different between different types of statins. Statins have different pharmacokinetic properties. Atorvsatatin, simvastatin, lovastatin, and cerivastatin are all metabolized by the cytochrome P450 isoenzyme 3A4 and co-administration of cyclosporine which may inhibit cytochrome P450 isoenzyme 3A4, increases statin levels and therefore increases the risk of rhabdomyolysis. Fluvastatin is metabolized by cytochrome P450 isoenzyme 2C9 and no clinically significant interactions with cyclosporine have been reported. Atorvastatin with co-administration of cyclosporine in renal transplant patients may induce drug interactions, therefore we recommend the routine monitoring of muscle enzymes, in these cases. Here, we reported a case of rhabdomyolysis in a patient who received atorvastatin and cyclosporine with the review of the literature.

BACKGROUND/AIMS: Fabry disease is an X-linked recessive and progressive disease caused by alpha-galactosidase A (alpha-GaL A) deficiency. We sought to assess the prevalence of unrecognized Fabry disease in dialysis-dependent patients and the efficacy of serum globotriaosylceramide (GL3) screening. METHODS: A total of 480 patients of 1,230 patients among 17 clinics were enrolled. Serum GL3 levels were measured by tandem mass spectrometry. Additionally, we studied the association between increased GL3 levels and cardiovascular disease, cerebrovascular disease, or left ventricular hypertrophy. RESULTS: Twenty-nine patients had elevated serum GL3 levels. The alpha-GaL A activity was determined for the 26 patients with high GL3 levels. The mean alpha-GaL A activity was 64.6 nmol/hr/mg (reference range, 45 to 85), and no patient was identified with decreased alpha-GaL A activity. Among the group with high GL3 levels, 15 women had a alpha-GaL A genetics analysis. No point mutations were discovered among the women with high GL3 levels. No correlation was observed between serum GL3 levels and alpha-GaL A activity; the Pearson correlation coefficient was 0.01352 (p = 0.9478). No significant correlation was observed between increased GL3 levels and the frequency of cardiovascular disease or cerebrovascular disease. CONCLUSIONS: Fabry disease is very rare disease in patients with end-stage renal disease. Serum GL3 measurements as a screening method for Fabry disease showed a high false-positive rate. Thus, serum GL3 levels determined by tandem mass spectrometry may not be useful as a screening method for Fabry disease in patients with end stage renal disease.
