Vestibular neurectomy is known as an effective procedure in the management of intractable peripheral vertigo from Meniere's disease and other episodic peripheral vertigo disorders. Various approaches have been developed for selectively sectioning the vestibular nerve, in order to preserve hearing and avoid facial nerve injury. Vestibular neurectomy is performed in two patients with Meniere's disease to control intractable episodic vertigo through retrolabyrinthine approach. Vertigo was improved with preserving their hearing. We report the surgical technique and advantages of retrolabyrinthine vestibular neurectomy in the treatment of vertigo.

OBJECTIVE: The authors report an analysis of clinical data including incidence, clinical manifestations, diagnostic tools and surgical treatment of neoplasms of scalp and calvarium in adults. METHODS: The clinical, radiological, and pathological records of 67 patients who underwent mass excision in scalp or skull at our department during recent five years were reviewed. RESULTS: The mean age was 43 years(range 16 to 85 years) and male to female ratio was 42 : 25. There were 62 scalp and five calvarial masses. Among scalp masses, there were 52 tumors, three vascular lesions, three inflammatory lesions and four miscellaneous lesions. The scalp tumors were composed of 44 benign lesions and nine malignant lesions. The most common type of scalp tumor was lipoma, followed by epidermoid and dermoid. The calvarial masses consisted of four osteomas and one eosinophilic granuloma. Surgical excision was carried out in all cases. CONCLUSION: Most scalp and calvarial masses are benign lesions, however, surgical excision seemed to be indicated in most cases for diagnosis and treatment.

Toxic epidermal necrolysis(TEN) is a severe drug induced life-threatening disease and an acute illness. This disease is characterized by rapid onset of widespread necrosis resulting in sloughing of epidermis. The incidence of TEN is very rare, with approximately 0.5 to 1.4 cases per million per year. but TEN has a high mortality rate of 25-40 percent. Therapy for TEN is primarily aimed at supportive care. Treatment with systemic corticosteroid, immunosuppresive agent such as cyclosporine, cyclophosphamide, pentoxifyllin or plasmapheresis have not been shown to improve outcome. Recently, administration of high dose intravenous immunoglobulin(IVIG) has been shown to result in rapid improvement in patients with TEN. There have been several reports of the benefit of IVIG in adult patients with TEN. However we could not find using IVIG in pediatric patient with TEN in Korea. We have experienced improvement in a 2 years old boy with TEN after using high dose IVIG.

An aneurysm of the distal superior cerebellar artery (SCA) is a highly rare disease. Fusiform aneurysms of the distal SCA are particularly challenging to treat. Clipping, trapping with or without bypass using microsurgery or endovascular treatment (EVT) were used to treat this condition. We describe the case of fusiform distal SCA aneurysms treated successfully with endovascular coiling with a 3-month follow-up. A 39 year-old male was presented with subarachnoid hemorrhage (SAH) and a 15 mm fusiform aneurysm of the ambient segment of the left distal SCA. EVT for parent artery occlusion and packing of the aneurysm was done. Left sixth nerve palsy appeared after 1 day of EVT. The symptom completely recovered within 1 week of the post-procedural period. No neurological deficit was seen during the clinical 3-month follow-up. EVT of fusiform distal SCA aneurysms with coils is a safe and feasible option to manage this rare condition. However, the treatment options must be carefully selected depending on the neurologic condition, development of collateral circulation, and configuration of the dissection.

A 35-years-old man was hospitalized with gene-ralized edema. 6 months ago, the patient was operated by radical subtotal gastrectomy for advanced gastric adenocarcinoma. The patient presented with multiple liver metastasis and the massive proteinuria. The patients renal biopsy revealed minimal change nephrotic syndrome and treated with prednisolone and diuretics. The patient was improved clinical symptome and decreased 24 hours urine protein. In literature reviewed, gastric carcinoma was not associated with minimal change nephrotic syndrome. We experienced advanced gastric carcinoma associated with minimal change nephrotic syndrome, thus we report it.

A 33-year old male was admitted due to continuous high spiking fever for 2 months via local clinic. He had been diagnosed pulmonary tuberculosis at local clinic. However, spiking fever had not been controlled by anti-tuberculous medications. Chest PA showed confluent consolidation on right upper & mid-lung field. 5 anti-tuberculous regimens (Streptomycin, Isoniazid, Rifampin, Ethambutol, Pyrazinamaide) were administered initially and steroid therapy was followed for relieving toxic symptoms Very slowly resolved chest X-ray lesion and continuous fever suggested the possibility of misdiagnosis. After 60th hospital day, the chest X-ray lesion was resolved gradually and fever subsided almost completely. He was discharged on 76th hospital day with anti-tuberculous drugs and steroid(prednisolon), without any other problems except sustained mild fever.

PURPOSE: To report the results of a new technique for intraocular lens scleral fixation of temporary haptic externalization and four-point fixation for enhanced stability. METHODS: Two 10–0 polypropylene strands were fixed at two points 2 mm apart on each haptic of a conventional three-piece intraocular lens, using our previously reported method of temporary haptic externalization after injector implantation. Postoperative refractive outcome and stability were evaluated. RESULTS: Although the intraocular lens was fixed at a total of four points, no intraoperative difficulties were observed during the process. Patients showed successful fixation of the intraocular lens postoperatively. The fixed intraocular lens showed good centering and minimal tilting. When compared to the two-point fixation technique, postoperative astigmatism was significantly smaller in the four-point fixation group (1.80 ± 0.84 vs. 1.00 ± 0.0.50, p = 0.033). Lens-induced astigmatism calculated from subtraction of corneal astigmatism from total astigmatism was also significantly smaller in the four-point fixation group (2.23 ± 0.98 vs.1.17 ± 0.0.70, p = 0.043). No postoperative complications were identified during a mean follow-up period of 14.8 months (range, 10 to 19 months). CONCLUSIONS: By fixing the intraocular lens at two points on each side of the haptics, this method minimizes the tilting of the intraocular lens and thus decreases postoperative lens-induced astigmatism. Also, the possibility of intraocular lens dislocation in the long term might be decreased by this two-point fixation technique.

OBJECTIVE: Both constitutive and inducible forms of nitric oxide synthase exist in endothelial cells. Disorders that produce acute lung injury frequently release endotoxin and cytoknes, such as interferon(IFNgamma) and tumor necrosis factor (TNFalpha). Endotoxin and these cytokines likely act as important mediators of cell injury. Because nitric oxide (NO) avidly reacts with iron, it may affect the activity of key enzymes, such as mitochondrial aconitase, which contain an iron-sulfur structure as a prosthetic group. METHOD: We studied the effect of IFNgamma, TNFalpha and E. coli lipopolysaccharide(LPS) on NO production and mitochondrial aconitase activity in cultured rat lung microvascular endothelial cells(RLMVC). RESULT: Exposing RLMVC for 24 hours to IFNgamma(500 U/mL), TNFalpha(300 U/mL) and LPS(5 microgram/mL) significantly increases nitrite production to 20+/-1 micrometer compared to 0.07 micrometer in control cells(P<0.05, n=4). Cytokine treatment also reduced mitochondrial aconitase activity from 196+/-8 to 102+/-34 nmole/min/mg of cell protein(P<0.05, n=4). Treatment with the inhibitor of nitric oxide synthase N-monomethyl-L-arginine(NMMA) (0.5 mM) not only significantly blunted the cytokine-mediated increase in nitrite formation (3+/-0.5 micrometer vs 20+/-1 micrometer with cytokines, P<0.05, n=4), but also prevented the cytokine-mediated drop in aconitase activity (161+/- 24 vs. 196+/-8 nmole/min/mg of cell protein, NS). CONCLUSION: Exposing RLMVC to IFNgamma, TNFalpha and E. coli LPS substantially decreases mitochondrial aconitase activity. Nitric oxide appears to mediate this effect. Our results suggest that the excessive production of NO by endothelial cells, in response to cytokines and endotoxin, may inhibit the function of the endothelial cell itself.
