PURPOSE: The chemoembolization with Lipiodol and doxorubicin hydrochloride is used in patients with hepatocellular carcinoma. What condition is the ideal emulsion of Lipiodol and doxorubicin for excellent anticancer effect? METHOD AND MATERIALS: Microscopic evaluation was performed on the emulsions, which were varied with different specific gravities of doxorubicin solutions, degrees in mixing of the emulsion, and amount of Lipiodol. RESULT: 1. Maximal amount of doxorubicin solution was contained in Lipiodol droplets and the release of doxorubicin from the droplets were delayed, when specific gravity of doxorubicin was equal to that of Lipiodol (SG, 1.28). 2. The optimal therapertic ratio of Lipiodol and doxorubicin was 3:2 at least, as in the emulsion less than 3:2, unmixed free forms of doxorubicin solution were increased. 3. The emulsion mixed by pumping 50--100 times had smaller Lipiodol droplets and contained larger amount of doxorubicin solution in the droplets than by pumping 20 times. CONCLUSION: We recommend the emulsion with specific gravity of doxorubicin equal to Lipiodol (SG. 1.28), the ratio of Lipiodol and doxorubicin closo to 3:2, and the mixture prepased with puming 50--100 times.

Intervertebral disc herniation is rare in adolescence, although several cases have been reported in the literature. We present three cases of lumbar disc herniation with low back pain and severe scoliosis (Cobb angle greater than 20 degrees). The patients had no prior history of trauma or collagen disease. Preoperative MRI scans showed L3-L4 (case 1), L4-L5 (case 3) and L5-S1 (case 2) disc herniations with no other bony or structural changes. Following discectomy, patient pain resolved, and scoliosis improved without further treatment. We conclude that severe scoliosis associated with disc herniation in young patients is likely secondary to pain and is not indicative of further structural changes.

Occasionally, a posterior fossa arachnoid cyst can induce compression of the spinal cord and cause syringomyelia. Here, we report the case of a 29-year-old man with both progressive shoulder pain and gait disturbance, who was found to have a huge retrocerebellar arachnoid cyst associated with syringomyelia. Accordingly, posterior fossa decompression and arachnoid cyst excision were performed. Post-operative MRI showed a marked reduction in the size of the arachnoid cyst and syringomyelia. The patient's symptoms were clearly improved compared to before surgery. In our view, treatment in such patients should focus on decompressing the foramen magnum and include the removal of the coexistent arachnoid cyst walls, which appear to be the crucial factor in development of syringomyelia. In this report, we discuss the pathogenic mechanisms underlying syringomyelia-associated retrocerebellar arachnoid cyst and review the current literature on this topic.

Vertebroplasty (VP) is a well-known therapeutic modality used to treat pain associated with vertebral compression fractures. Major complications such as cord or root compression, epidural and subdural hematomas (SDH) and pulmonary emboli, occur in less than 1% of patients who undergo VP after compression fracture. Spinal SDH is an extremely rare complication that usually happens a few hours after the procedure. We report a case of spinal SDH that developed at two weeks after a successful VP. We also reviewed related literatures and discussed its possible pathogenesis.

Benign neoplasms of the stomach are uncommon in children. They include adenomatous and hyperplastic polpys, leiomyomas, lipomas, and other lesions. Gastric leiomyoma in childhood represent only 1% of all gastrointestinal neoplasms reported, and slightly more than half of these are gastric. The tumor arises in the muscle layer of the stomach and is usually intragastric and submucosal. Barium contrast studies are useful in localizing leiomyoma with significant intramural or submucosal growth. An endoscopy can permit histologic confirmation if the tumor has eroded through the mucosa. Differentiation however, of malignant lesions from benign submucosal leiomyomas may be difficult. Using endoscopic ultrasonund imaging, highly accurate gastrointestinal tumor characterization, especially submucosal masses, and differentiation of malignant from benign lesion are now relatively possible without surgery. We experienced a case of a gastric submucosal tumor regarded as a leiomyoma, which was diagnosed using endoscopic ultrasonography, and report the findings with a review of related literatures.

The authors report an extremely rare case with intraventricular and subarachnoid fat developed after trauma to spine and soft tissue in a 54-year-old male. The initial computed tomography (CT) showed multiple low attenuation lesions, which were thought to be pneumocephalus. Cerebral magnetic resonance imaging (MRI) showed lesions with high signal intensity on T1-weighted magnetic resonance images and high signal intensity on T2-weighted images, indicating fat globules within the CSF. In this report, the clinical presentation, radiological findings, and a review of the literature are presented.

Closure of interdental spaces using proximal build-ups with resin composite is considered to be practical and conservative. However, a comprehensive approach combining two or more treatment modalities may be needed to improve esthetics. This case report describes the management of a patient with multiple diastemas, a peg-shaped lateral incisor and midline deviation in the maxillary anterior area. Direct resin bonding along with orthodontic movement of teeth allows space closure and midline correction, consequently, creating a better esthetic result.

Isolated noncompaction of the ventricular myocardium (INVM) is a rare cardiomyopathy resulting from a failure of normal endomyocardial embryogenesis and it has been categorized as a form of unclassified cardiomyopathy. The disorder is characterized by an excessively prominent trabecular meshwork with deep intertrabecular recesses. Although the disorder is sporadic, familial incidence may occur. Clinical symptoms and prognosis of INVM may differ markedly, and range from an asymptomatic course to a severe cardiac disability. The diagnostic method of choice for IVNM is echocardiography, which reveals multiple prominent trabeculations with deep intertrabecular spaces communicating with the left ventricular cavity in the middle and apical segments of the left ventricle. The authors report a case of INVM in a family in which three adult members (a brother and two sisters) were found to be affected by this disorder. They were all asymptomatic. The diagnosis of the disorder was made first in the 36-year-old brother by transthoracic echocardiography (TTE) and multidetector CT (MD CT), during the process of preoperative evaluation for surgical treatment of low back intervertebral herniated disc. TTE and MD CT showed similar and peculiar findings of INVM. Echocardiographic screening in all first-degree relatives of this patient, in order to identify asymptomatic patients, demonstrated INVM in two elder sisters.

We present a rare case of fracture-dislocation at the level of the first sacral (S1) and second sacral (S2) vertebrae. The S1 was displaced forward into the pelvic cavity and was located just in front of the S2. Because the patient also had extensive neurological injury to the lumbar plexus and instability of the pelvic ring, surgery to stabilize the pelvis and to decompress the lumbar plexus was performed. The surgery was successful and the patient experienced marked improvement in neurological function.
