PURPOSE: To evaluate the usefulness, patterns and appearances of false positive lesions, and technical problems of CTAP(CT Arterioportography). MATERIALS AND METHODS: CTAP was done in 45 patients in whom hepatic lesions were suggested on other radiologic studies. CTAP findings were compared with the informations obtained by operations, biopsies, and follow-up imagings. Additional findings, which were not detected in other radiologic studies, false positive manifestations, and technical errors were analyzed. RESULTS: CTAP detected 51 additional hepatic lesions which are not detected in other imaging studies. Of the 51 lesions, ten were true positive hepatic tumors, 2 were inflammatory lesions and 39 were false positive .lesions. False positive lesions included perfusion defects of periportal and perifissural areas, subcapsular perfusion defects and nonlobar, nonsegmental geographic perfusion defects. In 2 cases, CTAP aided in deciding the surgical strategy. On the other hand, there were 4 cases causing interpretational confusion and 6 cases of improper imaging due to technical errors. CONCLUSION: CTAP was valuable in detection of additional hepatic cancer lesion as well as in making the treatment plan. However, since many false positive lesions and improper imaging due to technical error occur during the examination, the understanding of such problems is essential for correct interpretation of CTAP.

We report a case of a skin problem induced by a visual display t rminal in a 24-year-old female. The patient had erythematcn.is rashes, crusts on both zygomatic areas and upper eyelids with itching, burning and pain sensations after she had been exposed to her visual display terminal. After the cassation of exposure, her skin lesions were markedly improved. A proioction test with her own visual display terminal was positive.

Even though the nonketotic hyperglycemia is a metabolic disorder, it complicates hemic- horea-hemiballism rarely. Moreover, generalized chorea-ballism associated with nonketotic hyperglycemia in diabetes mellitus is very rare, so it has not been reported in Korean literature. Although the precise pathophysiologic mechanisms of these disorders are still poorly understood, deficiency of gamma aminobutyric acid (GABA) in nonketotic hyperglycemia or reduced GABAnergic inhibition by striatal lesion may increase inhibitory output to subthalamic nucleus. These result loss of pallidal inhibition and produce contralateral hemichorea-hemiballism. The striatal lesions, such as transient ischemia with reactive astrocytosis or small amount of petechial hemorrhage, are related with changes of magnetic resonance image (MRI) findings presumably. We report a diabetic old woman who developed generalized chorea-ballismus as a very rare complication of nonketotic hyperglycemia. Her brain MRI showed high signal intensity in left lentiform nucleus and right pallidum on T1 weighted images and low signal intensity in bilateral putamen on T2 weighted images with highly enhanced corresponding lesions on T1 weighted enhancement images.

Autism Spectrum Disorder (ASD) is characterized by persistent deficits in social communication and restricted, repetitive patterns of behavior and interest. Sleep problems are not uncommon in children with autism spectrum disorders. Symptoms of insomnia are the most frequent sleep problems in individuals with ASD. Sleep problems can cause significant difficulties in the daily life of children with ASD and their families. Genetic factor, deregulations of melatonin synthesis, extraneous environmental stimuli and psychiatric and medical conditions may cause sleep problems. The first line treatment of sleep problems in ASD includes managements for potential contributing factors and parent education about sleep hygiene care for child and behavioral therapy. Supplementation with melatonin may be effective before considering other medications, such as risperidone, clonidine, and mirtazapine.

Office-based KTP laser laryngeal surgery is suitable for patients who have difficulty undergoing general anesthesia or for whom it is not an option. It can also be offered as an alternative to patients who have a reluctance toward general anesthesia. This case involves a 50-year-old female who underwent general anesthesia surgery for a vocal fold polyp 4 years ago. The vocal fold polyp recurred, causing persistent hoarseness that significantly impacted her profession. The patient was unwilling to undergo second general anesthesia procedure. Therefore, office-based KTP laser laryngeal surgery was performed under local anesthesia. The patient has remained free of recurrence for 6 months post-surgery. In cases where vocal fold polyps recur after surgery, it may be beneficial to consider local anesthesia surgery, depending on the size of the lesion and the patient’s condition.
