PURPOSE: This study was done to identify the state of internet addiction and to investigate the relationships among internet addiction, depression and suicidal ideation in adolescents. METHOD: Participants were 1,670 high school students in an urban city. The Internet Addiction Scale was used to measure internet addiction, the DISC-MDD-SQ was used to measure depression, and the Suicidal Ideation Questionnaire-JR was used to measure suicidal ideation. RESULT: 38.1% of participants were perceived to be in the early stages of internet addiction and 1.5% reported heavy addiction. Overall the internet addiction scale score was 37.57(+/-12.52). The differences of internet addiction in sample characteristics were found to be significant in rank in class. The differences in DISC-MDD-SQ and IAS scores among the states of internet addiction were statistically significant. The level of internet addiction correlated positively to the level of depression and suicidal ideation. CONCLUSION: Based upon these findings, there were significant positive correlations among Internet addiction, depression, and suicidal ideation in adolescents. As schools are often the first line for the identification of potential life-threatening behaviors, nurses, especially school-based health professionals, need to be cognizant of measures and procedures for the assessment of Internet addiction, depression, and suicidal ideation.

The antiphospholipid antibody syndrome is cha- racterized by antibodies directed against either phos-pholipids or plasma proteins bound to anionic phos- pholipids. These antibodies have been characterized by lupus anticoagulants and anticardiolipin antibodies. Patients with the antiphospholipid antibody syndrome may display a constellation of clinical features including venous and arterial thrombosis, recurrent fetal losses, and thrombocytopenia. Although the majority of patients reported have a thrombotic microangiopathy, some have also seen membranous nephopathy as well as IgA nephropathy in a patient with anti-phospholipid antibody syndrome accompanying glo-merulonephritis. Authors experienced a 37-year-old male patient who presented with generalized edema at the moment of follow-up for primary antiphos-pholipid syndrome accampanying systemic thrombotic events. Anticardiolipin antibody-IgM positivity was detected by seroligic test but no evidence for systemic lupus erythematosus was found. Kidney biopsy showed mesangial IgA deposition without th throm-botic microangiopathy of gomerular capillaries and was diagnosed finally as primary antiphospholipid syndrome with IgA nephropathy. Patient's symptom was relieved with steroids and anti platelete agents and now he is being follow-up to out patient department. This case suggests some possibility that anticardiolipin antibody may induce the IgA nephropathy. Therefore clinician should have concern about the relationship between antiphospholipid antibody and immune mediate glomerulonephritis.

Twin-twin transfusion syndrome(TTTS) is a serious complication of monozygotic mu-ltiple pregnancy. TTTS is associated with high perinatal mortality rate. The acute form has been attributed to rapid transfer of blood through superficial artery-to-artery or vein-to- vein anastomoses during labor and delivery, resulting in a hypovolemic, anemic donor twin and a hypervolemic, plethoric recipient twin of similar birth weight. The authors present a case of acute twin-twin transfusion syndrome with a review of literature.

Several reports have described the usefulness of tumor markers detected in pancreatic juice for diagnosis of pancreatic cancer. We performed this study to evaluate the usefulness of tumor markers in pure pancreatic juice collected by duodenoscopic cannulation of pancreatic duct before and after injection of secretin. From April 1993 to July 1995, 8 cases of pancreatic cancer, 5 cases of benign pancreatic lesions, and 5 cases of benign biliary diseases without pancreatic lesion were involved. CEA and CA 19-9 immunoreactivity were measured by radioimmunoassay. Concentrations of CA 19-9 in pure pancreatic juice were significantly higher in patients with pancreatic cancer(median value; 3582, range 88.4-10410 IU/ml) than in control patients(median value 231, range 30.4-682 IU/ml)(p<0.05). Concentrations of CEA in pure pancreatic juice were not significantly different between patients with pancreatic cancer(median value: 6,5, range 1.0-152ng/ml) and control patients(median value: 4.0, range 1-17.2 ng/ml)(p>0.05). There was no significant correlation between levels of CA19-9, CEA in pancreatic juice and those levels in serum. The amounts of juice collected by duodenoscopic cannulation in patients with pancreatic cancer were 1.5+/- 0.9ml during 5 minutes before infusion of secretin, 11.3+/- 3.9ml, 10.8+/- 4.0ml, 10.6+/- 4.0ml in 5 minute interval after infusion of secretin. These results indicated that measurement of CA19-9 in pure pancreatic juice may be used as a marker for pancreatic cancer. Adequate amount of pancreatic juice was collected by duodenoscopic cannulation for evaluation of tumor marker, enzyme studies and cytology.

Ulcerative colitis is associated with various extra-intestinal manifestations, including rheumatic, dermatologic, ophthalmologic, biliary, and hematologic manifestations. Cutaneous findings are common extra-intestinal manifestations of ulcerative colitis, occurring in 10-20% of patients. Cutaneous manifestations include erythema nodosum, pyoderma gangrenosum, aphthous stomatitis, and acute febrile neutrophilic dermatosis. Treatments for these cutaneous manifestations include corticosteroids, cyclosporine, tacrolimus, mycophenolate mofetil, azathioprine, and infliximab. A 48-year-old male presented with an acute exacerbation of ulcerative colitis associated with multiple skin lesions on his face, thumbs, thighs, and feet. The final impression was neutrophilic folliculitis, which is an early form of pyoderma gangrenosum. The patient's skin lesions and colitis both improved with corticosteroids. There are rare published case reports of ulcerative colitis exacerbations associated with pyoderma gangrenosum that initiated as neutrophilic folliculitis of the face. This case report includes a review of the literature.

The association between nephrotic syndrome and intravascular coagulation has been known for more than a century, but it was not until 1948 that a thrombotic diathesis in nephrotic patients was proposed. The prevalence of thrmbo-embolic complications is much higher in adult patients. Deep vein thrombosis of the leg is the most common complications in nephrotic adult and was responsible for one-third of the thrombo-embolic complications of nephrotic children. Arterial thrombosis occurs less frequently and is seen primarily in childern. We present a case of acute anterior myocardial infarction in a young man with nephrotic syndrome, secondary to minimal change glomerulonephritis, in which thrombosis of the proximal left anterior descanding artery was the actual cause of acute myocardial infarction.

BACKGROUND: Bioactive glass-ceramics have the ability to directly bind to bones and have been widely used as bone graft substitutes due to their high osteoconductivity and biocompatibility. CaO-SiO2-P2O5-B2O3 glass-ceramics are known to have good osteoconductivity and are used as bone graft extenders. METHODS: This study aimed to evaluate the effects of the resorbing properties of glass-ceramics in bone fusion after producing and analyzing three types of CaO-SiO2-P2O5-B2O3 glass-ceramics with high osteoconductivity that had enhanced resorption by having an increased B2O3 content. The three types of CaO-SiO2-P2O5-B2O3 glass-ceramics with B2O3 contents of 8.0, 9.0, and 9.5 weight % were designated and grouped as P20B80, P10B90, and P5B95, respectively. Glass-ceramic types were tested for fusion rates and bone formation by employing the lumbar 5-6 intertransverse process fusion model in 51 New Zealand male rabbits. Bioactivity was assessed by soaking in simulated body fluid (SBF). RESULTS: In vitro study results showed sufficient hydroxycarbonate apatite layer formation occurred for P20B80 in1 day, for P10B90 in 3 days, and for P5B95 in 5 days after soaking in SBF. For the rabbit lumbar spine posterolateral fusion model, the autograft group recorded a 100% fusion rate with levels significantly higher than those of P20B80 (29.4%), P10B90 (0%), and P5B95 (14.3%), with high resorbing properties. Resorbing property differences among the three glass-ceramic groups were not significant. Histological results showed new bone formation confirming osteoconductivity in all three types of glass-ceramics. Radiomorphometric results also confirmed the resorbing properties of the three glass-ceramic types. CONCLUSIONS: The high resorbing properties and osteoconductivity of porous glass-ceramics can be advantageous as no glass-ceramics remain in the body. However, their relatively fast rate of resorption in the body negatively affects their role as an osteoconductive scaffold as glass-ceramics are resorbed before bony fusion.

Autoimmune hepatitis (AIH) is an immune-mediated chronic liver disease characterized by hepatocellular inflammation, necrosis, and fibrosis, which can progress to cirrhosis and fulminant hepatic failure. The standard treatment for AIH includes corticosteroids alone or in combination with azathioprine. Although most patients achieve remission using the standard regimen, some patients do not respond due to either drug intolerance or refractory disease; in such cases alternative immunosuppressive agents should be explored. The second-line therapies are cyclophilin inhibitors such as cyclosporine A or tacrolimus, and nowadays mycophenolate mofetil (MMF) is widely used if azathioprine-based therapies are not tolerated. Although these are recommended as an alternative to the first-line regimen, there is insufficient evidence for the efficacy of second-line therapies, with the evidence based mainly on expert opinion. Therefore, we report an AIH patient receiving the standard regimen in whom remission did not occur due to side effects to azathioprine, but was successfully treated with MMF in combination with corticosteroids as an alternative to the standard regimen.
