Brown tumor of bone is a severe form of skeletal complication in patients with hyperparathyroidism. The main sites of involvement are the mandible, sternum, ribs, pelvis and femur. Involvement of the spine is less common. We report here a case of brown tumor of the spine that developed in a patient with right parathyroid adenoma.

PURPOSE: This study compared the total antioxidant status (TAS) and superoxide dismutase (SOD) activity in the saliva of periodontally compromised patients before and after scaling and root planing (SRP) to assess their diagnostic utility. METHODS: Severe chronic periodontitis patient (test group) and subjects with no attachment loss, sites showing a 3 mm or more probing depth and a sulcus bleeding index < 10% (control group) were enrolled in this study. Saliva sampling and clinical examination were performed at one week, one month and 3 months after SRP. The TAS and SOD activity in each patient's saliva was measured for the comparative analysis between the groups. RESULTS: In the test group, the TAS decreased directly after SRP. With time, it increased slightly and was relatively unchanged compared to the baseline. In the control group, the TAS also decreased immediately after SRP but increased gradually with time until 3 months. The SOD activity in the test and control subjects decreased immediately after SRP until 1 month. At 3 months, the SOD activity had increased. Both groups had a similar profile of SOD activity. However, the SOD activity of the control group was significantly higher than that of the test group at each point in time (P < 0.05). CONCLUSIONS: There was a significant difference in the total salivary antioxidant level between the periodontitis and healthy or gingivitis (control) group during the experiment period. The total antioxidant level in the saliva was higher in the patients with severe chronic periodontitis than the healthy or gingivitis control before SRP. The SOD activity of the periodontitis patients was lower than the control at each time point. These findings conclusively reveal the possible use of saliva as a diagnostic tool for periodontal health.

Clinical, EEG and MRI assessments were conducted in 320 consecutive seizure patients referred to the Yonsei Epilepsy Clinic from october 1, 1991 to Feburary 28. 1993 Clinical assessment suggested that 91.9% of our patients had partial seizures and only 3.1% had generalized seizures. Among partial seizures. Temporal lobe seizure uas considered in 37.5%, localization undetermined partial seizure in 29.7%, extratemporal lobe seizure in 24.7%. Correlation with EEG findings in these patients showed disconcordance rate of 34.6% in generalized seizure, 29.1% in extratemporal lobe seizure, 15.8% in temporal lobe seizure, 5.3% in localization undetermined partial seizure. Structural lesions in MRI were found in 51.6% with hippocampal atrophy being the most frequently round(59.4%). Focal encephalomalacia comprised 15.8%, focal atrophy in 4.8*/o. vascular malformation in 4.2%, granuloma in 3.7%, tumor in 3.7%, cyst in 2.4%. Patients with clinically judged temporal lobe seizure had the most common structural lesions in MRI. Which were seen in 59.2%. Extratemporal lobe seizure had focal lesion in 50.6%. Localization undetermined partial seizure in 50.5%, and generalized seizure in 23.1%. Among 98 patients with hippocampal atrophy, 27 patients(27.6%) had dual pathology with focal encephalomalacia being the most common. 11 patients(11.3%) were suspected to have bilateral hippocampal atrophy. Hippocampal atrophy was more commonly seen in patients with history of febrile convulsion and in patients with severe seizure.

Mauriac syndrome consists of a triad of poorly controlled diabetes, profound growth retardation and hepatomegaly. We experienced a case of Mauriac syndrome in an 18-year-old girl who had poorly controlled diabetes mellitus, short stature, hepatomegaly and central obesity. Also at the time of examination, she had complications of diabetic cataract and nephropathy. Fourteen years prior to admission, she was diagnosed as diabetes mellitus at a hospital. Thereafter, she had been managed with irregular insulin injection. On physical examination at admission, her height was 135cm(<3 percentile) and her weight was 39kg(<3 percetile). She was short and obese. The liver was 5 cm palpable below the right subcostal margin. Her sexual maturation was Tanner stage I. On ophthalmologic examination, the cataracts were observed on both eyes and diabetic retinopathy was absent. Diabetic nephropathy could not be confirrned by kidney biopsy due to her mother's refusal. We studied the hormonal, radiographic and histological abnormalities. The hormonal study was normal and the bone age was by delayed as much as 10 years. The liver biopsy revealed glycogen accumulation in hepatocyte. She was consistent with Mauriac syndrome. She was managed by strict diabetic control with insulin therapy, diabetic diet and intensive education. She was discharged with well controlled blood glucose. Five months later, growth acceleration and sexual maturation have not been observed, but hepatomegaly subsided. (J Korean Pediatr Soc 2000;43-837-841)

This study was carried out to examine the action mechanism of Chamaecyparis obtusa oil (CO) on hair growth in C57BL/6 mice. For alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (gamma-GT) activities in the skin tissue, at week 4, the 3% minoxidil (MXD) and 3% CO treatment groups showed an ALP activity that was significantly higher by 85% (p < 0.001) and 48% (p < 0.05) and an gamma-GT activity that was significantly higher by 294% (p < 0.01) and 254% (p < 0.05) respectively, as compared to the saline (SA) treatment group. For insulin-like growth factor-1 (IGF-1) mRNA expression in the skin tissue, at week 4, the MXD and CO groups showed a significantly higher expression by 204% (p < 0.05) and 426% (p < 0.01) respectively, as compared to the SA group. At week 4, vascular endothelial growth factor (VEGF) expression in the MXD and CO groups showed a significantly higher expression by 74% and 96% (p < 0.05) respectively, however, epidermal growth factor (EGF) expression in the MXD and CO groups showed a significantly lower expression by 66% and 61% (p < 0.05) respectively, as compared to the SA group. Stem cell factor (SCF) expression in the MXD and CO groups was observed by immunohistochemistry as significant in a part of the bulge around the hair follicle and in a part of the basal layer of the epidermis. Taking all the results together, on the basis of effects on ALP and gamma-GT activity, and the expression of IGF-1, VEGF and SCF, which are related to the promotion of hair growth, it can be concluded that CO induced a proliferation and division of hair follicle cells and maintained the anagen phase. Because EGF expression was decreased significantly, CO could delay the transition to the catagen phase.

BACKGROUND AND OBJECTIVES: It has been assumed that salivary glands receive secretory fibers both from parasympathetic and sympathetic nerves. In fact, however, the existence of sympathetic secretory fibers in the cervical sympathetic nerve has not been established yet, because the salivary response to the cervical sympathetic stimulation is variable and short-lasting, and it tends to cease in spite of continued stimulation. This study investigated whether or not the cervical sympathetic nerve contains specific secretory fibers. MATERIALS AND METHODS: Salivary and blood flow responses to different frequency stimulation of the cervical sympathetic nerve, and often some autonomic drugs administration were observed from the submandibular gland in chloralose-anesthetized cats. RESULTS: 1) Low frequency stimulation (1-2 Hz) of the sympathetic nerve did not evoke salivary outflow and any change of blood flow, whereas high frequency stimulation of the nerve evoked salivary outflow and decrease of blood flow, in which salivary response tended to cease in spite of continued stimulation. 2) The salivary and blood flow responses to high frequency stimulation (20 Hz) of the nerve were not affected by the intravenous administration of propranolol, but were abolished by regitine. 3) Noradrenalin evoked salivary outflow and decreased blood flow which were not affected by the administration of propranolol but were abolished by regitine. 4) Isoproterenol increased blood flow but did not evoke salivary outflow, and the blood flow response was abolished by propranolol. CONCLUSION: These results suggest that the cervical sympathetic nerve does not contain specific secretory fibers and salivary outflow response to high frequency stimulation of the nerve may be due to either excitation of motor fibers innervating contractile elements of the excretory duct or chemical transmitters released from the vasomotor fibers.

Apert syndrome is an uncommon congenital disorder characterized by malformation of the skull in association with symmetrical syndactyly of both hands and feet. This syndrome is autosornal dominant. The original description was presented by Apert in 1906. Since then more than 200 cases have been reported in the world. Recently, we experienced a case of newhorn male infant with congenital anomalies of the skull and extremities. Molecular biologically, he was found to have Ser252Try mutation in the FGFR2 exonIIIa. A brief review of literature was made.

PURPOSE: To determine the usefulness of the functional MRI (fMRI) using motor and sensory stimuli in patients with brain tumors or focal cerebral lesions. MATERIALS AND METHODS: This study involved five patients with brain tumors (n=2) or cerebral lesions [cysticercosis (n=1), arteriovenous malformation (n=1), focal infarction (n=1)] and seven normal controls. For MR examinations a 1.5T scanner was used, and during motor or sensory stimulation, the EPI BOLD technique was employed. For image postprocessing an SPM program was utilized. RESULTS: In volunteers, contralateral sensori-motor cortices were activated by both motor and sensory stimuli, while supplementary motor cortices were activated by motor stimuli and other sensory cortices by sensory stimuli. Preoperative evaluation of the relationship between lesions and important sensory and motor areas was possible, and subsequent surgery was thus successful, involving no severe complications. Activation of ipsilateral or other areas occurred in patients with destruction of a major sensory and/or motor area, suggesting compensatory reorganization. CONCLUSION: fMRI could be a useful supportive method for determining the best approach to surgery treatment in patients with brain tumors or focal cerebral lesions.

OBJECTIVES: The purpose of this study was to develop the Korean version of the Social Adjustment Scale II-Revised Version (KSAS II-RV) in the schizophrenics. METHODS: KSAS II-RV was administered to 67 schizophrenic patients and 78 matched normal controls for examining the reliability and validity. RESULTS: Data analysis showed statistically significant reliabilities and validities of KSAS II-RV. The test-retest reliability, inter-rater reliability, and internal consistency for total scores of KSAS II-RV were 0.85, 0.89. and 0.87, respectively. Evidence for discriminant validity of KSAS II-RV comes from the results that the mean scores of schizophrenic patients were significantly high than those of normal controls. Construct validity was assessed by calculating the 10 inter-subareas correlations of the KSAS II-RV, and all except the sexual adjustment area were statistically significant. Significant correlations between the global area scores of KSAS II-RV and those of Global Assessment of Functioning Scale lend support for the concurrent validity of this instrument indirectly. CONCLUSION: KSAS II-RV was found to be a valid and reliable instrument which can be used to evaluate the degree of social adjustment in the schizophrenic patients.
