Idiopathic intracranial hypertension, a syndrome of obscure origin, occurs particularly in fat adolescent girls and young women. The usual symptoms are headache, blurred vision, a vague dizziness, horizontal diplopia and transient visual obscurations etc., and ophthalmoscopic examination reveals papillederma, due to increased ICP. Visual field testing usually shows slight peripheral constrictions with enlargement of the blind sports. CSF pressure is elevated in the range of 250 to 450 mm of water. Radiological or the other laboratory tests show no specific abnormalities. Treatment for idiopathic intracranial hypertension is focused on early detection and prevention of vision loss, the only permanent morbidity. Many different modes of medical treatment, including weight reduction, repeated lumber puncture, corticosteroids, diuretics, glycerol or carbonic anhydrase inhibitors, have successfully been tried up to 90% of the patients. In the remaining patients, particularly in those with measurable impairment of vision that does not respond to conventinal medical therapies, surgical procedure should be considered. We report a case of idiopathic intracranial hypertension successfully treated with optic nerve sheath fenestration.

Spontaneous intracranial hypotension, a syndrome of low CSF pressure, occurs without preceding events such as lumbar puncture, back trauma, operative procedure or medical illness. The most characteristic symptom is a headache that may be severe when the patient is upright and relieved when the patient is recumbent. Associated symptoms include neck stiffness, nausea and vomiting, tinnitus, vertigo and subdural effusion or hematoma. This syndrome usually resolves spontaneously or with strict bed rest. When the headache persists or is incapacitating, more aggressive treatment may be necessary. Autologous epidural blood patch is highly effective in the management of spontaneous intracranial hypotension. We report a case of spontaneous intracranial hypotension successfully treated with epidural blood patch.

Protein C exerts anticoagulatory effects by inactivating factor V and VII and stimulating fibrinolysis. Hereditary protein C-deficient individuals have an increased risk of venous thrombosis and thromboembolism at young age. To our knowledge, the deep cerebral venous thrombosis associated with protein C deficiency has not been reported in Korea. A 34-year-old man was admitted to our hospital because of sudden onset of headache with nausea, vomiting and ocular pain. He had suffered from recurrent deep vein thrombosis of the right lower extremity for one year. Brain MRI showed thrombosis of the straight and confluent sinuses and venous infarction of the right thalamus. The result of cerebral angiography corresponded to MRI findings. Protein C antigen concentration was decreased to 65% and its functional activity was 37%. Other coagulation test and routine blood examination was normal. The protein C level of his mother was low in both antigen and activity, but protein C levels of three siblings were normal in functional activity. We speculate that the etiology of the deep cerebral venous thrombosis in this patient is associated with protein C deficiency and suggest it is valuable to measure protein C level in patients with cerebral venous thrombosis.

Patients with acromegaly have a reduced life expectancy rnainly due to cardiovascular, respiratory or cerebrovascular diseas-. Malignancy also seems to occur with greater than the expected incidence. In particular, the published retrospective or prospective studies have suggested a strong association of colonic neoplasia with acromegaly. But, there were a few reports of thyroid cancer in acrornegaly. We report a case of thyroid papillary cancer derived from diffuse goiter in acromegaly, sugge- sting the possible carcinogenic role of growth hormone.

PURPOSE: We evaluated the utility of magnetic resonance imaging (MRI) and 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) for the preoperative staging of invasive lobular carcinoma (ILC) of the breast and compared the results with those of invasive ductal carcinoma (IDC). METHODS: The study included pathologically proven 32 ILCs and 73 IDCs. We compared clinical and histopathological characteristics and the diagnostic performances of MRI and 18F-FDG PET/CT for the primary mass, additional ipsilateral and/or contralateral lesion(s), and axillary lymph node metastasis between the ILC and IDC groups. RESULTS: Primary ILCs were greater in size, but demonstrated lower maximum standardized uptake values than IDCs. All primary masses were detected on MRI. The detection rate for ILCs (75.0%) was lower than that for IDCs (83.6%) on 18F-FDG PET/CT, but the difference was not significant. For additional ipsilateral lesion(s), the sensitivities and specificities of MRI were 87.5% and 58.3% for ILC and 100.0% and 66.7% for IDC, respectively; whereas the sensitivities and specificities of 18F-FDG PET/CT were 0% and 91.7% for ILC and 37.5% and 94.7% for IDC, respectively. The sensitivity of 18F-FDG PET/CT for ipsilateral lesion(s) was significantly lower in the ILC group than the IDC group. The sensitivity for ipsilateral lesion(s) was significantly higher with MRI; however, specificity was higher with 18F-FDG PET/CT in both tumor groups. There was no significant difference in the diagnostic performance for additional contralateral lesion(s) or axillary lymph node metastasis on MRI or 18F-FDG PET/CT for ILC versus IDC. CONCLUSION: The MRI and 18F-FDG PET/CT detection rates for the primary cancer do not differ between the ILC and IDC groups. Although 18F-FDG PET/CT demonstrates lower sensitivity for primary and additional ipsilateral lesions, it shows higher specificity for additional ipsilateral lesions, and could play a complementary role in the staging of ILC as well as IDC.

Gaucher's disease is an autosomal recessive disorder caused by a deficiency of beta-glucosidase (glucocerebrosidase) which results in an accumulation of glucocerebroside in various organs and tissues. Type 3 (juvenile or subacute neuro-pathic) Gaucher's disease, presented here as progressive myoclonus epilepsy, occurs more rarely than type 1 (adult or nonneuropathic) or type 2 (infantile or neuropathic) Gaucher's disease. Two patients (brother and sister) with type 3 Gaucher's disease had or was expected to develop typical features of progressive myoclonus epilepsy: myoclonus, seizures, dementia, and cerebellar dysfunction. One of them showed Gaucher cells in a liver biopsy specimen and decreased beta-glucosidase activity (14% of normal) in the cultured skin fibroblasts, which confirmed the clinical diagno-sis of type 3 Gaucher's disease.

PURPOSE: The purpose of this study is to evaluate the effect of different wave length of low power laser on early fracture healing. METHODS AND MATERIALS: Nine week old female English Hartley guinea pigs were used for this experiment. Sixty guinea pigs were divided into three groups, and then right femur was fractured and fixed with an intramedullary nail. The frequency of 632 nm and 830 nm semi-conductor laser machines were used. Finally, 46 guinea pigs were survived (including 14 cases in control group, 16 cases in 632 nm group and 16 cases in 830 nm group). Guinea pigs were sacrificed at 3 and 6 weeks separately. The gross, radiologic and histologic findings were assessed by the Modified Zorlu Scoring System. The statistical evaluation was done by repetitive measured ANOVA test. RESULTS: In the gross findings and radiologic findings, both of 632 nm and 830 nm radiation groups showed a greater amount of callus formation at postoperative 3 weeks with statistical significance (P<0.01) compared to the control group. Quantity of callus formation in 830 nm group was larger than that in 632 nm group although there was no significant difference (P>0.05). The result of histological findings showed that an increase of osteoblastic proliferation in two radiation groups was greater than that in the control group at 3 and 6 weeks (P<0.01). Enhancement of osteoblastic proliferation was greater in 830 nm group compared to in 632 nm group at 3 weeks (P<0.05). The comparison between the experimental groups for wave length of 632 nm and 830 nm at 6 weeks showed significant difference (P<0.05). CONCLUSION: In this study, it became known that applying 632 nm and 830 nm wavelength laser to the fracture site accelerate bony union, and 830 nm wavelength laser showed earlier bony union than 630 nm wavelength laser.

Plasma cell myelomas generally manifest as bone or soft-tissue tumors with variable mass effects, pain, and infiltrative behavior. Extramedullary involvement occurs most commonly in the spleen, liver, lymph nodes, and kidneys, but intracranial involvement in plasma cell myeloma is a rare extramedullary manifestation. These authors recently encountered a case of intracranial involvement of plasma cell myeloma. A 69-year-old man was hospitalized for headache and mental changes. Brain CT showed subdural hemorrhage caused by plasma cell myeloma. Plasma cell myeloma with intracranial involvement has poor prognosis, and the patient in this case died from acute complications, such as subdural hemorrhage. Based on this case report, it is suggested that more effective treatment regimens of plasma cell myeloma with intracranial involvement be developed. Moreover, a screening method and decision on the appropriate time for intracranial involvement are needed for plasma cell myeloma patients.

The radiation-induced occlusive vasculopathy has been known as the one of the side effects of radiation therary The gamma knife for stereotactic radiosurgery has been used popularly as a valuable adjunctive therapeutic option in some patients with pituitary tumors for its accuracy and effectiveness. But the long term complication of gamma knife have not been revealed until now. In spite of the remarkable improvement in radiologic technology, the side effect of radiation induced vasculaopathy remains an unsolved issue. We experienced the occlusion of intracranial portion of the internal carotid artery in one patient with pituitary adenoma, who had been treated with gamma knife radiosurgery previously.
