The medical records of 117 patients with spinal tumors who underwent surgery with pathologic confirmation from January 1999 to April 2004 at Kaohsiung Medical University Hospital were reviewed. Data from this review were compared with those obtained from the same institution 10 years earlier (covering the period 1988-1995) and from other reported series. There were 69 male and 48 female patients aged from 13 to 87 years old (mean age, 51.9). The most common pathologic findings were metastasis in 45.3% (53/117), nerve sheath tumors in 28.2% (33/117), meningiomas in 12% (14/117) and neuroepithelial tumors in 6% (7/117). The peak ages at diagnosis were 41-50 years and 61-70 years. A slight male predominance was noted for all tumors, except meningiomas. Motor weakness, even paralysis, was the major clinical presentation (64-86%), followed by sensory deficits (50%) and pain (42%). The location of tumors was most often in the thoracic (50.4%; 59/117), lumbosacral (27.4%; 32/117) and cervical spine (22.2%; 26/117) segments. Among the metastatic tumors, the lung (22.6%) and breast (15.1%) were the most common primary sites of origin, followed by unknown origin, the liver (hepatocellular carcinoma), the gastrointestinal tract and the nasopharynx (nasopharyngeal cancer).

Dermatomyositis (DM) is an idiopathic inflammatory myopathy (IIM) with typical cutaneous manifestations. It has been proposed that DM may be caused by autoimmune responses to viral infections, and previous studies have also shown that an association between DM and malignancy. However, chronic hepatitis B virus (HBV) infection associated with DM and hepatocellular carcinoma (HCC) is rarely encountered. The authors report a case of DM and HCC in a patient with a HBV infection. A 58-year-old man presented erythematous skin rashes on a sun-exposed area of 2 year's duration, and recent proximal muscle weakness. His medical history revealed that he had a chronic HBV infection. A diagnosis of DM relies on proximal muscle weakness, elevated muscle enzymes, myopathic changes (demonstrated by electromyography), muscle biopsy evidence of myositis, and its characteristic cutaneous findings. A Liver mass in the left lobe visualized by abdominal computed tomography was confirmed histologically as HCC. This case suggests that DM associated with HCC might be caused by a HBV infection.

Brain metastases from hepatocellular carcinoma are extremely rare. The objectives of the current study were to assess the natural history, outcome, and possible prognostic factors in patients with brain metastases from hepatocellular carcinoma. Between 1995 and 2006, 6,919 patients with hepatocellular carcinoma were treated at Yonsei University Health System. Of those, 62 (0.9%) had a diagnosis of brain metastasis. We carried out a retrospective review of these 62 patients and performed a statistical analysis. The median age at the time patients were diagnosed with brain metastasis was 54 years. Forty-seven patients (76%) were male, and 53 patients had hepatitis B. Median time from diagnosis of hepatocellular carcinoma to brain metastasis was 18.2 months, and 5 patients had brain involvement as their initial presentation. Intracranial hemorrhage was frequently associated (54.8%) with brain metastasis. The most common presenting symptoms were motor weakness, mental change, and headache. Metastases were treated with whole-brain radiation therapy (WBRT) alone in 17 patients and gamma knife surgery alone in 10 patients. Six patients underwent surgical resection and 5 patients were treated with surgical resection followed by WBRT. Twenty-four patients (39%) received steroids only. Median survival after diagnosis of brain metastasis was 6.8 weeks (95% confidence interval: 3.8-9.8 weeks). Univariate analysis showed that treatment modality, number of brain lesions, alpha-fetoprotein, ECOG performance score, recursive partitioning analysis (RPA) class, and Child-Pugh classification had a statistically significant impact on survival. In multivariate analysis, treatment modality, number of brain lesions, and Child-Pugh classification were statistically significant prognostic factors for survival. The overall prognosis of patients with brain metastases from hepatocellular carcinoma is extremely poor. Nevertheless, some subsets of patients manifested the most favorable survival criteria (single brain metastasis and good liver function); thus, for at least these patients, treatment may result in an improved survival time.

A 12-year-old, neutered male, mixed-breed dog was presented to The Ohio State University Veterinary Teaching Hospital with a history of weight loss and weakness. Laboratory abnormalities reported by the referring veterinarian during the past year included increased alkaline phosphatase (ALP) activity, hyperalbuminemia, and nonregenerative anemia. On referral, the dog appeared hydrated and had moderate muscle wasting and hepatomegaly. A large lobular hepatic mass was observed ultrasonographically. Laboratory results included mild to moderate nonregenerative anemia, urine-specific gravity of 1.035, 3+ proteinuria, increased serum activities of alanine aminotransferase (229 U/L, reference interval 10-55 U/L), ALP (813 U/L, reference interval 15-120 U/L), and the steroid-induced isoform of ALP (676 U/L, reference interval 0-6 U/L), marked hyperalbuminemia (5.3 g/dL, reference interval 2.9-4.2 g/dL), and an increased A/G ratio (1.7). Hyperalbuminemia was confirmed by reanalysis on 2 different analyzers and by agarose gel electrophoresis, and colloid osmotic pressure (COP) was markedly increased (42.5 mmHg, reference interval 20-25 mmHg). Cytologic examination of a fine-needle aspirate of the hepatic mass indicated hepatocellular proliferation; histologic examination of an excisional biopsy confirmed hepatocellular carcinoma. Three weeks after surgery, the albumin concentration, A/G ratio, COP, and ALT activity had normalized, but ALP activities remained high. We hypothesized that hyperalbuminemia developed secondary to hepatocellular carcinoma due to increased synthesis of albumin by malignant hepatocytes or due to decreased negative feedback from impaired hepatocellular osmoreceptivity. Hepatocellular carcinoma has been associated with paraneoplastic secretion of other proteins, but hyperalbuminemia has been reported only once in a human patient and has not previously in dogs.

A 25-year-old man with hepatocellular carcinoma developed severe muscular weakness and pain 15 days after transcatheter arterial chemoembolization (TACE). The diagnosis of rhabdomyolysis was made based on myalgia localized in the bilateral upper extremities (bilateral trapezius, deltoid, biceps brachii, and teres major muscles) on magnetic resonance imaging and increased levels of muscle-derived serum enzymes. In this case, some drugs administered during the clinical course of TACE (diclofenac, famotidine, and cefotiam dihydrochloride) were suspected to be involved in the rhabdomyolysis, but the exact cause of rhabdomyolysis was not identified. The symptoms were completely improved by right trisegmentectomy of the liver following conservative treatment.

Transcatheter arterial chemoembolization (TACE) is the mainstay of treatment for unresectable hepatocellular carcinoma (HCC). Although various complications of TACE have been reported, cerebral lipiodol embolism after TACE is rare. We report a 67-year-old man, who had patent foramen ovale and developed cerebral lipiodol embolism after TACE via the inferior phrenic artery. At 20 months after third TACE of 3 cm sized HCC in the left hepatic lobe, computed tomography (CT) revealed about 1.6 cm newly developed HCC in the anterior superior segment of right hepatic lobe. The angiogram revealed the HCC was supplied from the right inferior phrenic artery. Toward the end of TACE, there were accumulations of the iodized oil in the pulmonary vasculature. Immediately after TACE, he complained of weakness in right upper and lower limbs and sensory decrease in right limbs and right hemitrunk. Magnetic resonance imaging revealed a cerebral lipiodol embolism. Transesophageal echocardiography revealed no visible thrombi but contrast-echocardiography using hand agitated saline revealed an intracardiac right to left shunt consistent with patent foramen ovale. Motor weakness and sensory decrease were gradually improved, and all neurological symptoms disappeared over 4 weeks.

A man in his late fifties was treated with acitretin for psoriasis. The treatment was discontinued when liver enzymes started to increase. He subsequently developed erythrodermia, weakness of proximal muscle groups, heliotrope rash, Gottron's papules and elevation of creatine kinase to more than 9000 U/L. However, histological examination of a muscle biopsy displayed neuropathic atrophy and only a few scattered necrotic fibers. Alpha 1 foetoprotein was substantially elevated (1600 kU/L) and computed tomography showed two hepatic tumors, lytic lesions in the spine and in the ninth rib. Although no chronic liver disease could be documented, the patient was found to have a hepatocellular carcinoma which presented as dermatomyositis and erythrodermia.

We report a case of cerebral lipiodol embolism after transarterial chemoembolization of hepatocellular carcinoma, which was confirmed by dual-energy computed tomography (CT). A 44-year-old male patient developed left leg weakness after transarterial chemoembolization for hepatocellular carcinoma. The noncontrast CT scan of his brain revealed multiple high-attenuating lesions scattered along the gyral surface of the both cerebral hemispheres; meanwhile, the lesions disappeared on the iodine-removed virtual noncontrast images generated from dual-energy CT.

We developed microfluidic-based pure chitosan microfibers (approximately 1 meter long, 70-150 microm diameter) for liver tissue engineering applications. Despite the potential of the chitosan for creating bio-artificial liver chips, its major limitation is the inability to fabricate pure chitosan-based microstructures with controlled shapes because of the mechanical weakness of the pure chitosan. Previous studies have shown that chitosan micro/nanofibers can be fabricated by using chemicals and electrospinning techniques. However, there is no paper regarding pure chitosan-based microfibers in a microfluidic device. This paper suggests a unique method to fabricate pure chitosan microfibers without any chemical additive. We also analyzed the chemical, mechanical, and diffusion properties of pure chitosan microfibers. Attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectrometry and electron spectroscopy for chemical analysis (ESCA) were used to analyze the chemical composition of the synthesized chitosan microfibers. We measured the mechanical axial-force and diffusion coefficient in pure chitosan-based microfibers using fluorescence recovery after photobleaching (FRAP) techniques. Furthermore, to evaluate the capability of the microfibers for liver tissue formation, hepatoma HepG2 cells were seeded onto the chitosan microfibers. The functionality of these hepatic cells cultured on chitosan microfibers was analyzed by measuring albumin secretion and urea synthesis. Therefore, this pure chitosan-based microfiber chip could be a potentially useful method for liver tissue engineering applications.
