Pseudohypoparathyroidism is a medical disorder characterized by a complex disorder of renal resistance to parathyroid hormone and the mechanism underlying the disease is still unclear. The authors described two cases of pseudohypoparathyroidism in sibling,who had metabolic anomalies(hypocalcemia and hyperphosphatemia, high circulatin immunoreactive PTH)and basal ganglia calcification. Bilateral basal ganglia calcifications, which was not visible on plain skull film, was detected by CT scan of brain MRI. We report these cases with a review of related literatures.

BACKGROUND AND OBJECTIVE: The clinical manifestation of Henoch-Schonlein purpura and existance of renal involvement may influence on its course and prognosis. To verify prevention with early administration of steroid, we studied the efficacy of corticosteroid treatment. MATERIAL AND METHOD: We analysed 65 children under 15 years of age with Henoch-Scho nlein purpura according to their age, sex, and seasonal incidence. Forty children showed typical skin lesions, arthralgia and abdominal pain. We have divided them two groups. Group A consisted of 20 children who received 1 mg/kg of prednisolone/perday for 2 weeks and group B did not. We carried out their physical examination and urinalysis monthly for a year. RESULT: The main clinical manifestations were skin rash(100% ), abdominal symptoms(41.5 %), joint symptoms (49.2%), and renal involvement(34%). As for gastrointestinal symptoms, abdominal pain(66.7% ) was most commonly observed one and others were nausea or vomiting (44.7%) and melena(25.9%). The joint involvement was observed mostly in knee(56.3%) and ankle joint(31.3% ), Hematuria was observed in all cases with renal involvement and proteinuria, in 28% of them. The improvement of renal manifestations were noted in 84.2% of them within 4 months. Mild elevation of IgA was more frequently observed in renal involvement group than non-involved group (p< 0.01). There were no significant differences in immonologic parameters such as IgG, IgM, IgE, duration of the acute phase and severity of cutaneous symptoms between two growps. None of steroid treated growp showed progression of nephropathy. Of the 20 non-steroid treated growp, 2(10%) developed nephropathy. Conclusion We may suggest that existance of renal involvement in Henoch-Schonlein purpura influences its course and prognosis.

OBJECTIVE: The purpose of this study was to describe the MR imaging appearance of the dural ligaments which is connected between the anterior dura mater and the posterior longitudinal ligament. MATERIALS AND METHODS: In 10 cadavers with formalin fixation, the dural ligaments were evaluated and photographed after removal of the posterior element of the spinal canal. MR studies of 12 patients who had distinct dural ligaments were evaluated. Spin-echo MR images were obtained on a 1. 5T unit. RESULTS: In seven of the ten cadavers, the midline dural ligament was observed; the lateral dural ligament was observed in 3 cadavers. On MR, the dural ligaments were imaged as thin lines of low signal intensity between the anterior dural margin and the posterior longitudinal ligament. Dural ligaments were well-visualized at the level of the lower lumbar spine which had a more prominent anterior epidural space than that of the upper level of the spine. Eight of 12 cases had well developed midline dural ligaments. Two cases showed distinct lateral dural ligaments and the remaining 2 cases had distinct midline and lateral dural ligaments. CONCLUSION: MR images of the dural ligament demonstrate a thin low signal line at the anterior epidural space.

PURPOSE: Sentinel lymph node (SLN) biopsy is thought to be a highly accurate method of assessing axillary nodal status in breast cancer. Furthermore, it can improve axillary staging by providing a more detailed examination of selected lymph nodes with a high probability of metastasis rather than the entire axillary nodes. The purpose of this study was to assess the incidence of SLN micrometastasis in node-negative breast cancer. METHODS: SLN biopsy was performed in 40 patients with clinically node-negative breast cancer using vital blue dye and/or radioisotope methods; the blue dye method was used in 21 cases, the isotope method in 14 cases, and a combination of both methods in 5 cases. All lymph nodes were evaluated by routine pathologic examination, and a more detailed examination was performed on sentinel nodes in node-negative cases; sentinel nodes were serially sectioned at an interval of 40micrometer depth followed by H&E and cytokeratin immunohistochemical (IHC) staining. RESULTS: Sentinel nodes were detected in 35 of 40 patients (87.5%). The mapping technique used in the remaining 5 cases was vital blue dye method only. Axillary node metastasis was found in 16 of 40 patients. Sentinel node biopsy accurately reflected the axillary node status in all cases; the sensitivity, specificity, and overall accuracy were 100, 100 and 100%, respectively. In 11 of 16 node-positive patients (68.8%), sentinel nodes were the only metastatic nodes. Occult micrometastases were found in SLN by serial section and IHC staining in 4 of 19 patients diagnosed as node- negative by routine pathological examination (21.1%). Occult micrometastasis of SLN was not correlated with primary tumor size, histologic grade or lymphovascular invasion with the exception of the S-phase fraction (P=0.023). CONCLUSION: SLN biopsy was a highly accurate method of assessing axillary node metastasis in breast cancer. Serial sectioning and IHC staining of SLN were sensitive methods in the detection of occult lymph node metastasis.
