BACKGROUND AND OBJECTIVES: We aimed to evaluate the clinical manifestation and treatment outcome of the nasal cavity squamous cell carcinoma (SCC) and compared its survival rate with that of the maxillary sinus (MS) SCC. SUBJECTS AND METHOD: Thirty two patients who were diagnosed as nasal cavity SCC or ethmoid sinus SCC between 1984 and 2005 were selected. These patients were referred to as the intranasal (IN) SCC group. Ten prognostic factors were evaluated in terms of survival rate and recurrence. The survival rate of 61 patients who were diagnosed as MS SCC was compared with that of the IN SCC. RESULTS: Chief complaints of the patients with IN SCC were nasal obstruction (40.4%), epistaxis (25.0%), and rhinorrhea (13.5%). The 5 year survival rate of IN SCC was 44.6% and the 5 year disease free survival rate was 27.7%. The most important prognostic factor was T stage (p<.001). The 5 year survival rate of MS SCC was 55.4%, and it was statistically not different from that of the IN SCC (p=.472). In the T1, T2, T3 stages, the 5-year-survival rate of the IN SCC was similar to that of MS SCC (p=.637). But in the T4 stage, IN SCC tended to have a worse prognosis (p=.074). CONCLUSION: The prognosis of IN SCC was similar to that of the MS SCC. However, MS SCCs were detected in a more advanced stage and T4 stage of the IN SCC had a worse prognosis compared to the same stage of MS SCC.

For the past two years, nephropexy using PCN was underwent in 9 cases of nephroptosis (8 patients) with variable degrees of flank pain. All were female and 6 on right, 1 on left and 1 on bilateral. All patients had a very mobile kidney and exact distance of movement measured on the film was greater than 6cm (6 to 15 cm). After this operation, 14-20 Fr. nephrostomy catheter was indwelled for about two weeks. All patients were followed at least 3 months(3 to 32, median 17 months). We followed the patients with symptom relief and IVP after 3 months. Nephropexy was regarded as success if she remained asymptomatic for more than 3 months. Five cases were successful and four cases felt recurrent flank pain within 1 month after the surgery. Among four cases of recurrence, one had repeated PCN and got successful result, another had open nephropexy and the others have been followed so far So overall success rate was 67% (6/9). In conclusion, nephropexy using PCN is less invasive, needs shorter period of admission and leaves ignorable scars postoperatively. Furthermore it can be repeated even in the case of failure or recurrence, which would make this new technique available as the first step for the surgical treatment of nephroptosis. And the success rate could be increased if the nephrostomy tract is dilated upto 30 Fr. and the PCN catheter is placed about 4 weeks.

OBJECTIVES: This study was carried out to investigate the clinical availability of topographic auditory event related potential P300 as a biological marker in children with attention deficit hyperactivity disorder(ADHD). METHODS: The subjects were composed of children with ADHD(n=22:16 boys, 6 girl s:mean age=89.8+/-17.1months) and normal controls(n=20:12 boys, 8 girls:mean age=90.6+/-16.8months). Topographic auditory event related potential was measured by "oddball paradigm", and the latencies and amplitudes of P300 of both groups were determined by Global Field Power Measurement. After 8 weeks treatment with methylphenidate, P300 of ADHD children were also measured. RESULTS: Both P300 latency and amplitude were not different between ADHD children after treatment and normal controls, but significantly different between ADHD children before treatment and normal controls, and between before and after treatment of ADHD children. CONCLUSIONS: The results implicate that the latency and amplitude of P300 may be considered as state markers of ADHD.

Hypertensive encephalopathy is a medical emergency that is usually presented with manifestating headache, nausea, and visual disturbance. The disease predominantly involves the parieto-occipital white matter. Although cerebellar lesion accompanying hydrocephalus has been occasionally described in the literature, medical management has been sufficient for relieving the posterior fossa hypertension. In the present case, we report a patient who was diagnosed with primary hypertensive cerebellar encephalopathy refractory to medical management and who was successfully treated by surgical decompression of the posterior fossa. A pathologic microscopic inspection of the tissue specimen confirmed hypertensive vascular change.

BACKGROUND: Hepatitis B virus(HBV) DNA integration is one of the cause of hepatocellular carcinoma (HCC). Epidemiologic evidences indicate that HBV infection is associated with the high risk of development of HCC. We wanted to evaluate the HBV DNA integration in hepatocellular carcinoma. So we detected HBV DNA by PCR in aseptically obtained 37 HCC tissues. METHODS: A total 37 surgical specimens from HCC patients were evaluated. Patient's serologic findings were analyzed retrospectively. Serologic markers were tested by radioimmunoassay. Genomic DNA was extracted from HCC paraffin blocks by microwave oven method. PGR was done. RESULTS: The sensitivity of HBV DNA PCR was 100 fg. Among 37 Patients tested, 30 cases of HCC patients had HBV DNA in their liver tissue. Among 25 HBs Ag positive patients, 23 had PCR positive results. All of the anti-HBc positive patients had HBV DNA. CONCLUSIONS: These findings are highly suggestive of HBV infection in the development of hepatocellular carcinoma. Detection of HBV DNA in patients with hepatocellular carcinoma is highly suggestive of HBV infection in the development of hepatocellular carcinoma.

This study was designed to examine the mianserin effects on the negative symptoms of chronic schizophrenia. The chronic schizophrenics(N= 14) diagnosed by DSM-III-R, who were treated at the Catholic University St. Mary Hospital from March 1, 1993 to August 31, 1995, were divided into two groups. One group was composed of 7 patients who were treated with a single classical antipsychotic agent(monotherapy group, MG), and another was composed of 7 Patients treated with combined medications(combined therapy group, CG), including classical antipsychotics plus fixed dose of mianserin 30 mg/day at bed time. Symptoms were evaluated by BPRS(Brief psychiatric Rating Scale) and PANSS(Positive and Negative Syndrome Scale) biweekly for 6 weeks, i.e., total 4 times(at baseline, at 2 weeks, at 4 weeks, and at 6 weeks). The results were as follows: 1) Assessed by PANSS, the negative symptoms of CG were statistically significantly improved more than those of MG at 2 weeks, at 4 weeks, and at 6 weeks. 2) Assessed by PANSS, the positive symptoms of CG were not statistically different from those of MG. In both of CG and MG, there was no difference of the positive symptoms across time intervals. 3) Assessed by PANSS, the total symptoms of CG were statistically significantly improved more than those of MG at 2 weeks, at 4 weeks, and at 6 weeks. But, assessed by BPRS, the total symptoms of CG were not statistically different from those of MG. 4) Assessed by PANSS, the general psychopathology symptoms of CG were not statistically different from those of MG. In CG, the general psychopathology symptoms at 6 weeks were statistically significantly improved more than those of baseline. In summary, mianserin, when combined with classical antipsychotic agent, appears to be effective in diminishing negative symptoms of chronic schizophrenic patients. However, it did not influence positive symptoms.
