Pupose:Recently childhood obesity is increasing and has been accompanied by an increase in the prevalence of type 2 diabetes mellitus(DM) among children and adolescents. We evaluated insulin resistance and impaired glucose tolerance(IGT) in 48 obese children and adolescents. METHODS:All subjects underwent a two-hour oral glucose tolerance test(1.75 g of glucose per kg of body weight) and then glucose and insulin levels were measured. Insulin resistance was estimated by homeostatic model assessment, and betacell function was estimated by calculating the ratio between the changes in the insulin level and glucose level during the first 30 minutes after the ingestion of glucose. RESULTS:IGT was detected in 4.2% of the 24 obese children(4-10 years of age) and 20.8% of the 24 obese adolescents(11 to 18 years of age). Type 2 DM was identified in 8.3% in children and 29.2% in adolescent obesity. Insulin levels were markedly elevated after the glucose tolerance test in subjects with IGT but a little decreased in cases with DM. Those changes of insulin levels were not significant statistically. The insulinogenic index was decreased in IGT and DM group of childhood and adolescent obesity compared to normal glucose tolerance(NGT) but it was not significant statistically. Insulin resistance, which was evaluated with fasting insulin, QUICKI and HOMA-IR, was increased in childhood obesity compared with adolescent obesity and the HOMA-IR of adolescent IGT group was significantly higher compared with NGT group(P<0.05). CONCLUSION: IGT is highly prevalent among children and adolescents with obesity. IGT was associated with insulin resistance and hyperinsulinemia, while beta-cell function was still relatively preserved. Overt type 2 diabetes was linked to insulin resistance and to beta cell failure.

The authors attempted to choose what has the best reproducibility and predictability for prognosis of the prostatic adenocarcinoma among four most widely used gradings methods; the Gleason's Mostofi's, Bocking and MD Anderson hospital systems. According to these gradings systems, each of two pathologists made histologic gradings of 40 consecutive prostatic adenocarcinomas which had been diagnosed with the surgically resected specimens. Correlation between the histological grades and the clinical stages was studied and a comparison was made among each system. For the comparison, the Gleason's and MDAH systems were revised as 3 grades and adjusted to the other gradings systems. In this study, MDAH grading system yielded the highest reproducibility as represented by 90% agreement, as compared with the other systems which showed 82.5~87.5% agreement. By the Gleason's, Mostofi's and Bocking's systems, 46.2%, 23.1% and 46.2% of grade 3 tumors respectively fell under the clinical stage A. On the contrary, there were no cases of grade 3 in stage A and no cases of grade 1 in stage D, by MDAH gradings system. These results suggest that MDAH gradings system is superior to the other systems in reproducibility and for predicting the biological behavior.

Reading epilepsy, a form of reflex epilepsy or sensory precipitated epilesy, is known as the most frequent type of language induced epilepsy. Since Bickford presented 6 cases of reading epilepsy for the first time, about 50 cases of primary reading epilepsy have been reported. We present a case of primary reading epilepsy which is confirmed by clinical features and EEG, with a brief review of literature.

Spinal anesthesia is a safe anesthetic technique and relative easy to perform, but occasionally neurologic injuries after spinal anesthesia have been reported. A 53-year old female patient visited the emergency room due to abdominal pain and she was diagnosed with acute appendicitis. Thus, an emergent appendectomy was planned. During the preoperative evaluation, we noticed that she had a history of intermittent low back pain for the previous 5 years. However, because her stomach was not fully empty, we decided to administer spinal anesthesia. When the spinal needle passed the subarachnoid membrane, she suddenly complained of severe paresthesia on her right posterior thigh. However the parethesia subsided soon, and 2.2 cc of 0.5% bupivacaine was injected via a spinal needle, and aftewards, an appendectomy was done without any complications. As she recovered from the spinal anesthesia, she started complaining of shooting, stabbing and burning pain on her right buttock and posterior thigh Because a neurologic injury after spinal anesthesia was suspected, we inserted an epidural catheter to the same lumbar vertebral level for administering the mepivacaine and ketamine mixture and we also performed a right second sacral nerve root block and a lumbar sympathetic ganglion block. Magnetic Resonance Imaging showed spondylosis of lumbar spine and associated disc degeneration and a bulging disc at the L3-4, L4-5 and L5-S1 level. After treatments, her symptoms improved gradually. When she was discharged on the 16th hospital day, she complained of only minor discomfort on her right posterior thigh.
