A 31-year-old man presented with dull headache and memory disturbance lasting for one week. Computed tomographic scans revealed acute hydrocephalus. The cerebrospinal fluid contained 53 leukocytes/mm3, with a mononuclear preponderance and no erythrocytes. Magnetic resonance imaging revealed hydrocephalus and leptomeningeal enhancement. Magnetic resonance angiography and digital subtraction angiography showed supraclinoid occlusion of the right internal carotid artery, which resembled unilateral moyamoya disease. Neuroendoscopic biopsy of a lesion in the septum pellucidum revealed noncaseating granulomas, which was consistent with sarcoidosis. The patient was successfully managed with intravenous methylprednisolone and ventriculoperitoneal shunting. To our knowledge, this is the first case of moyamoya-like vasculopathy associated with neurosarcoidosis.

We have constructed several panels of MAbs which specifically recognize B-subunit of HCG (BHCG). Splenocytes from Balb/c mice immunized with B-subunit of HCG were fused with SP2/o-Ag14 myeloma cells by PEG method. Fifteen different hybridorna clones (individually named as mG10.127, mG10.61, mG9.5, mG9.18, rnG9.20, mG6.3, mG6.36, mG6.8, mG7.31, mG7.79, mG9.11, mG9.51.6, mG9.51.12, mH4.17, and mH4.4) were obtained by indirect ELISA screening and three to five successive cloning procedures. The distinct features of these MAbs were determined by specificity, western blot, isotyping, and isoelectrofocusing. All of the MAbs except mG9.20 and mG6.8 specifically bind to BHCG without cross- reaction with B-subunit of LH (BLH). In western blot analysis, all of the MAbs bind to non-denatured form of BHCG suggesting that the MAbs recognize conformation-dependent epitope of BHCG. This new panels of MAbs to BHCG should be useful for developing diagnostic reagent such as pregnancy, choriocarcinoma, Down's syndrome as well as for the fine quantitation of serum or urinary HCG.

The authors describe a case of intradural epidermoid tumor in which the patient presented with low back pain and weakness of right lower extremity. The magnetic resonance imaging study showed intraspinal mass lesion at L2-3. The patient had no history of previous lumbar puncture. It was removed totally through laminectomy of L2 and L3 without any injury of the neural structure. The pathological findings were compatible with epidermoid tumor. The postoperative course was uneventful without any neurologic deficit. Characteristics of this lesion with a pertinent literature is reviewed.

We had replaced 159 hips in 130 patients with cementless porous-coated AML porsthesis at Kwang Ju Christian Hospital between April 1987 and Feb. 1992. Among them, 100 cases(80 patients) could be analyzed clinically and radiologically with an average follow-up of 38.5 months(range 10 months to 74 months). The purpose of this study was to evaluate the relationships of initial fit, follow up stability and clinical results. The results were as follows. 1. The average postoperative Harris hip score was 90 points(preop. 42) at the follow-up of 1 year or more, the pain score 41 points(preop. 15). 2. When the surgical fit of stem was achieved properly, fixation by bone ingrowth could be expected. Simultaneously adequate fit of acetabular cup provided stable fixation. 3. The incidence of thigh pain was high in patients with an unstable implant of stem and the hip pain was more common in group of a definitely unstable cup. 4. Stress shielding was seen in 44 cases(44%). Of the 44 cases, 38 cases(86%) revealed in bone ingrowth. In conclusion, this study showed good clinical result of THR using AML prosthesis at the average follow-up of 38.5 months and it seemed to be influenced by initial fit significantly. But long-term follow-up is needed for accurate clinical and radiological evaluation.

PURPOSE: Although there are significant risks, retrobulbar anesthesia is commonly used for eye surgery. We report two cases of Purtscher-like retinopathy, a rare complication. CASE SUMMARY: (Case 1) A 76-year-old female visited our hospital because of decreased vision. She underwent right cataract surgery with retrobulbar anesthesia. After 7 days, she had decreased visual acuity (VA) and a constricted visual field. Multiple white spots and cotton wool spots around the optic nerve and post pole, macular edema (ME), and subretinal fluid (SRF) were found using a fundus examination. A non-perfusion area and staining of the vascular wall were seen using fluorescence angiography. Although carotid arterial angiography, thrombolysis, and intravenous injection of high-dose steroids were performed, the ME and SRF persisted. After intravitreal aflibercept was injected twice (2-month interval), the ME and SRF decreased and remained stable. (Case 2) A 61-year-old male underwent left cataract surgery with retrobulbar anesthesia. After anesthesia, the VA of the left eye was 10 cm finger count. The fundus examination showed multiple hemorrhage blots and retinal hemorrhages, and hyperfluorescence around the optic nerve and post pole; vascular wall staining revealed a Purtscher-like retinopathy. Left carotid arterial angiography, thrombolysis, and intravenous injection of high-dose steroids were then performed. After treatment, the VA of the left eye, ME, and SRF were improved at the 4-month follow-up. CONCLUSIONS: We report rare complications of retrobulbar anesthesia, with active and timely treatment having a positive impact on the visual prognosis.
