The nerve root block or selective nerve root block is one of the primarily preoperative diagnostic tool to identify and confirm the lesion site of primary cause of pain and that is considered as one component of a comprehensive treatment program. The purpose of our study is to evaluate the effect and duration of the pain control by selective spinal nerve root block as a conservative treatment in patients presenting with chronic or recurrent sciatica. The authors performed 95 selective nerve root blocks in 72 patients from Sep. 1994 to May. 1996, (mean follow up 11.6 month) at the department of orthopedic surgery, Kosin University Gospel Hospital, and the results were as follows: 1. Among 72 cases, spinal stenosis was in 45 cases (62.5%), HIVD in 19 cases (26.4%), failed back syndrome in 5 cases (6.9%), spondylosis in 2 cases (2.8%), and spondylolisthesis in I case (1.4%). 2. In 72 cases, improved more than 50% of sciatica were 61 cases (84.7%) at 3 hours, 53 cases (73.6%) at I week, 35 cases (48.6%) at 1 month, 33 cases (45.8%) at 3 months, and 33 cases (45.8%) at 6 months respectively. 3. At last follow-up, excellent and good results were 35 cases (48.6%), fair results were 25 cases (34.7%) and poor results were 12 cases (16.7%) by the Kirkaldy-Willis criteria. 4. Complications were 1 case of transient hypotension, 2 cases of severe paresthesia, but subsided without residual complication. Therefore, the selective nerve root block is one of the valuable procedure that is helpful and extremely safe in useful treatment for radicular pain associated with lumbar disease. And the trial of selective nerve root block was recommended before deciding surgical intervention on an outpatient basis.

The lesions of central nervous system in tuberous sclerosis often calcify, especially those present in the perivascular region, allowing the computed tomography to make early and definite diagnosis, even when patients intelligence was normal, seizures were absent, or clinical findings were not specific, We report three cases of tuberous sclerosis, which showed pathognomic subependymal paraventricular calcification in brain CT.

Although uterine arterovenous malformation(AVM) is a rare cause of menorrhagia or postmenopausal bleeding, it is important to consider that curettage may precipitate life-threatening hemorrhage and therefore it is contraindicated when AVM is suspected. Special investigations such as hysteroscopy, Doppler flow ultrasound and angiography are important diagnostic tools, and transarterial embolization(TAE) has replaced hysterectomy as the treatment of choice in women who wish to retain their fertility. But due to the high incidence of collateral vessels, recurrence of the vascular malformation after TAE is common. We have experienced two cases of AVM, one of which was managed by TAE in combination with surgical arterial ligation.

Chromophobe cell renal carcinoma is an uncommon variety of renal cell carcinoma first described in humans in 1985 by Thoenes and his colleagues. It is a distinct type of renal cancer presumably derived from the intercalated cells of the collecting duct system and exhibiting a better prognosis than other types of renal cell carcinoma. This type of renal cell carcinoma has not been reported in Korean literature. We experienced three cases of chromophobe cell renal carcinoma from surgical pathology files of Dong-A medical center. The patients were a 65-year-old female, a 54-year-old female, and a 50-year-old male who had 8.2x6 cm, 4x2.5 cm and 4.3x3.2 cm sized, yellowish gray, beige to tan colored masses in the kidneys, respectively. Microscopically, the tumor cells were arranged in sheets or nests with delicate intervening vasculature. The cells were voluminous, uniform in appearance and contained finely reticulated cytoplasms delineated by prominent cell borders. With Hale's iron colloid staining the cytoplasm showed positive reaction; with PAS staining the result was negative. Immunohistochemically, the tumor cells showed positive reaction for cytokeratin but negative for vimentin. Electron microscopy showed numerous small, round to oval cytoplasmic vesicles, 150-300nm in size. All the patients received only radical nephrectomy and survived without evidence of recurrence or metastasis during follow-up intervals ranging from 4 months to 5 years.

Spontaneous spinal epidural hematoma is a rare entity. Various definitions for spontaneous epidural hematoma have been reported in the literature. The expression of nontraumatic spinal epidural hematoma seems to be less ambiguous and includes idiopathic hematomas and hematomas secondary to coagulopathy, vascular malformations, and tumors. We report three cases of nontraumatic spinal epidural hematomas observed from 1991 to 2000. The causes of the spinal epidural hematomas were not clear in two cases among them, but in the another one case, the cause was determined to be an acquired coagulopathy. We reviewed 24 cases reported in the Korean Journal of Neurosurgery and our three cases with particular emphasis on the various causes such as coagulopathy, vascular malformations and tumors. Among the 27 cases, numerous causes were detected such as three cases of vascular malformation, one case of anticoagulant treatment, five cases of combined lumbar disc herniation, two cases associated with pregnancy and postpartum, one case associated with hypertension, and one case associated with ossification of ligamentum flavum. No causes were detected in the ten cases. The authors reviewed the literature.

Immunohistochemical studies of the molecules associated with gastric tumor progression and metastasis were done to evaluate their relationship with known prognostic factors and their usefulness in assessment of the progression of gastric carcinoma in 127 gastric carcinoma tissues. The 4 antibodies used in this study were CD44H, CD44v6, erbB-2, and p53. The CD44H expression was detected in 76 (59.8%), CD44v6 in 63 (49.6%), erbB-2 in 18 (14.2%), and mutant p53 in 98 (77.2%) out of 127 cases of gastric carcinomas. There was no significant correlation between the expression rates of each four proteins. The expression rates of all 4 proteins were not significantly correlated with age and sex of the patients and lymph node metastasis, but the correlation between CD44v6 expression and the depth of tumor invasion and tumor stage was significant (p<0.05). These results suggest that CD44v6 is closely associated with tumor invasion, and high levels of CD44H, erbB-2 and p53 are associated with tumorigenesis of the stomach as they are highly expressed in early as well as in advanced gastric carcinomas. The findings also support the conclusion that the loss of control of alternative CD44 mRNA splicing resulted in production of CD44v6 splicing variant in tumor cell facilitates tissue invasion by increased adherence of the tumor cell to an extracellular matrix or by tumor cell migration. It can be expected that CD44v6 overexpression in tumor cells appears to be an important prognostic indicator for gastric tumor progression.
