The grading of astrocytoma has traditionally relied on histological assessment, but there are some differences in their parameters, application, and reproducibility. Recently, numerous studies have attempted to correlate biological aggresiveness with tumor proliferation index using new immunohistochemical methods. The purpose of this study is to correlate the histopathological grades of astrocytoma with the expression of Ki-67, PCNA, p53 protein and AgNORs. The paraffin sections of 41 consecutive cases of astrocytomas were examined. Histologically the tumors were graded as three groups under the St. Anne-Mayo system and showed 14 cases in grade II, 15 cases in grade III and 12 cases in grade IV (glioblastoma multiforme). As a result, the Ki-67 labelling index and p53 protein expression tended to increase with increasing grade of malignancy. But the univariate analysis showed that there was no significant difference between the tumor grades (p>0.05). The PCNA labelling index and number of AgNORs revealed striking differences between the grade II and grade III astrocytomas (p<0.05). We concluded that the PCNA labelling index and AgNORs counting are useful markers for differentiation between grade II and III astrocytomas.

PURPOSE: Abnormalities in calcium(Ca), vitamin D and bone mineral density (BMD) associated with antiepileptic drug(AED) are reported, but the results are inconsistent. In case of intractable epilepsy, poor growth and altered bone mineral metabolism may be prominent, possibly related to previous long-term use of multiple AED and poor activity. The aim of this study was to assess growth status, concentrations of calcium regulating hormones and BMD in children with intractable epilepsy. METHODS: Sixty-six intractable epilepsy patients aged 0.8 to 14.7 years(mean+/-D:4.6+/-.6 years) were included in the study. Height and weight were measured and then height SDS and weight SDS were calculated. Serum Ca, i-Ca, P, Mg, Zinc, osteocalcin, intact-PTH, 25-OHD, 1,25(OH)2D were measured. BMD of the lumbar spine was measured by dual energy X-ray absorption. RESULTS: Most of the patients showed normal height SDS and weight SDS. Percentage of severe short stature(height SDS <-2) was 1.5% and tall stature(height SDS >2) was 4.5%. Percentage of severe thin(weight SDS <-2) was 1.5% and obesity(weight SDS >2) was 6%. Duration of AED was not related to height SDS or weight SDS. Etiology of epilepsy and physical activity were not related to height SDS and weight SDS. Most of them had normal Ca, iCa, P, Mg, Zinc, intact-PTH, osteocalcin, 25-OHD and 1,25(OH)2D concentrations. BMD was not related to the levels of Ca, i-Ca, P, Mg, intact-PTH, osteocalcin, 25-OHD, 1,25(OH)2D. BMD was not related to the duration of AED. BMD positively correlated with age(r=0.75, P>0.01) and body weight(r=0.72, P<0.01). CONCLUSION: Most of the children with intractable epilepsy, who regularly visits epilepsy clinic, showed normal growth and normal bone mineral metabolism, but careful monitoring about growth and bone mineral metabolism is needed.

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by thunderclap headache with reversible vasoconstriction of the cerebral arteries. RCVS has been reported to occur in various clinical settings. However, RCVS triggered by blood transfusion is rare. A 50-year-old woman had severe anemia and received multiple blood transfusions. She developed thunderclap headache after transfusion. Cerebral artery vasoconstrictions were demonstrated by magnetic resonance angiography and transfemoral cerebral angiography. RCVS might be triggered by red blood cell transfusion in patients with severe anemia.

PURPOSE: To evaluate the correlation between central corneal thickness (CCT) and retinal nerve fiber layer thickness (RNFLT) as determined by optical coherence tomography (OCT) in glaucomatous subjects. METHODS: One hundred eyes diagnosed with glaucoma and 99 glaucoma suspect (GS) eyes were tested by visual field (VF), OCT, and ultrasonic pachymetry. The relationship between CCT and RNFLT measurements was assessed by Pearson correlation analysis. A mixed effect model was employed to determine the relationship between CCT and RNFLT in glaucoma and GS groups. We divided the patients into two groups depending on the thickness of their corneas: Thin (< 553.6 micrometer) and thick (> or = 553.6 micrometer), and compared three parameters: VF mean deviation (MD), pattern standard deviation (PSD), and RNFLT between the two groups. RESULTS: There were no significant correlations between CCT and RNFLT in any participant (R2=0.00, p=0.88). There was no significant relationship between CCT and RNFLT in glaucoma and GS groups (p=0.11, p=0.46). There were no statistically significant differences in MD, PSD, or RNFLT between the thin and thick cornea groups (p=0.38, 0.32, 0.44). CONCLUSIONS: CCT is not significantly associated with RNFLT in glaucoma and GS subjects.

Fine needle aspiration cytology of the salivary lesions was performed on 221 patients at Soonchunhyang University Hospital for 10 years. Of 221 aspirates, 6 aspirates(2.7%) were inadequate, 116 cases(52.5%) were non-neoplastic lesions, 76(34.4%) cases were benign neoplasms and 23 cases(10.4%) were malignant neoplasms. The cytologic diagnoses could be correlated with histologic findings in 58 cases. FNAC correctly discriminated between neoplastic and nonneoplastic lesions in fifty-seven lesions and failed in a case, and overall accuracy, sensitivity, and specificity were 98.3%, 98.0%, and 100.0%. FNAC correctly discriminated malignant neoplasms from benign neoplastic/non- neoplastic lesions in fifty-three cases and failed in five cases, and overall accuracy, sensitivity, and specificity were 91.3%, 72.7%, and 95.7%. Among three false negative cases, two mucoepidermoid carcinomas were misdiagnosed as mucocele and benign neoplasm, and an acinic cell carcinoma were misdiagnosed as Warthin's tumor. Two false positive cases were a Warthin's tumor misdiagnosed as squamous cell carcinoma and a pleomorphic adenoma misinterpretated as suggestive of malignancy. In conclusion, diagnostic accuracy of FNAC of salivary lesions is high, and the possibilities of low grade mucoepidermoid carcinoma and acinic cell carcinoma should be considered on hypocellular smears with mucoid or fluidy background.

BACKGROUND: Epidural morphine has side effects, especially pruritus, nausea, and vomiting. Butorphanol has been added in studies to reduce these side effects in post cesarean patients. The purpose of this study was to evaluate the side effects and analgesic efficacy when a combination of epidural morphine and butorphanol was administered in patients having combined local anesthetic and opioid epidural infusion. METHODS: Sixty patients having epidural anesthesia for cesarean section were randomly divided into two groups. Group M (n=30) received a bolus of 0.25% bupivacaine 4 ml, morphine 2 mg, and saline 0.75 ml, whereas group B (n=30) received a bolus of 0.25% bupivacaine 4 ml, morphine 2 mg, and butorphanol 1.5 mg (0.75 ml). Continuous epidural infusion was done by Two-day Infusor containing either 0.25% bupivacaine 75 ml, morphine 5 mg, and saline 20 ml in group M or 0.25% bupivacaine 75 ml, morphine 5 mg, butorphanol 4 mg (2 ml), and saline 18 ml in group B. We compared the side effect and analgesic effect of group M to those of group B for 2 days. RESULTS: The incidence of pruritus and vomiting were reduced significantly in group B (p<0.05). There were no significant differences between both groups in the incidence of nausea or other side effects as well as no differences in analgesic effect. CONCLUSIONS: We conclude that the addition of butorphanol to morphine in combined local anesthetic and opioid epidural infusion for postoperative analgesia decreases the occurrence of pruritus and vomiting without significant increase of other side effects and adverse effect on analgesia.

A lateral chest radiograph is frequently useful and sometimes decisive in detecting chest pathology. Certainparts, such as the posterior wall of the bronchus intermedius (PWBI) and subcarinal regions, can be evaluated onlyon lateral chest radiograph. The authors present and emphasize the findings of PWBI and subcarinal abnormalities. Abnormal PWBI, more than 3 mm thick, is seen in cases of minor degree of oblique position, pulmonary edema, inflammation, neoplasm and enlarged lymph nodes. It can also be seen in patients with subcarinal mass. The findings of subcarinal mass on lateral view are ill-defined increased opacity, fullness of the inferior hilarregion, doughnut sign, extra-density and thickening of the PWBI. Detection of changes in the PWBI and subcarinalregion may be the only diagnostic evidence of hilar and subcarinal disease and helps in its early detection priorto computed tomography.
