BACKGROUND:Posterior lumbar interbody fusion can thoroughly decompress the central canal, which is the common surgical technique for the central type of lumbar disc herniation with intervertebral instability at low lumbar segment. However, due to the regular traction on dural sac and nerve root in the operation, lower limb radicular pain in the early stage is inevitable. OBJECTIVE:To evaluate the effect of local use of gelatin sponge containing prednisolone acetate around the nerve roots after posterior lumbar interbody fusion on lower limb radicular pain. METHED:Sixty-three cases of lumbar disc herniation with degenerative instability were devided into treatment group (n=21) and control group (n=42) based on the type of implants. Gelatin sponge containing prednisolone acetate was implanted into patients in the treatment group after posterior lumbar interbody fusion, while pure gelatin sponge was implanted into patients in the control group. RESULTS AND CONCLUSION:Compared with the control group, radicular pain in the treatment group was significantly relieved within 1 week after surgery. The visual analog scale score and Oswestry disability index score were similar between the two groups. There were three cases of radicular pain recurrence in the control group, but no incision infection and epidural hematoma after surgery in both two groups. In conclusion, local use of gelatin sponge containing prednisolone acetate around the nerve roots can significantly relieve lower limb radicular pain in the early stage after posterior lumbar interbody fusion in lumbar disc herniation, contributing to early rehabilitation exercise and patient satisfaction outcomes.

PURPOSE: To evaluate the relationship between the hormonal receptor status and the mammographic finding in breast cancer, thus to disclose whether the mammorgraphic findings would be the prognostic predictor or not. MATERIALS AND METHODS: Fifty breast cancer patients with hormonal receptor assay were included in this study. Hormonal status and mammographic findings were evaluated to disclose the relationship between the two variables. RESULTS: Among 26 positive estrogen receptor(ER) patients, 23 cases showed spioulations, 4 cases with increased parenchymal densities, 15 cases with calcifications, and 18 with mass-like lesions. Among 25 positive progesterone receptor(PR) patients, 22 cases showed spiculations, 6 with increased parenchymal densities, 12 with calcifications, 17 with mass-like lesions. Among 24 negative ER patients, 10 showed spiculations, 9 increased parenchymal densities, 12 calcifications, and 13 mass lesions. Among 25 negative PR patients, 17 showed spiculations, 8 increased parenchymal densities, 15 calcifications, and 13 mass lesions. CONCLUSION: Spiculation in mammography could related to the high incidence of positive estrogen receptor.

CT has become the most useful, non-invasive diagnostic method as the initial exmination in the diagnosis ofruptured intracranial aneurysm with intracranial hemorrhage(subarachnoid, intracerebral and intraventricularhemorrhage), hydrocephalus and infarction. Furthermore, high resolution CT can demonstrate aneurysm itself. Butangiography is the last and conclusive method as yet, for better evaluation of vascular anatomic structure ofaneurysm for surgery. Authors analyzed 40 cases of ruptured intracranial aneurysm confirmed by CT, angiographyand/or surgery at Chonnam National University Hospital from July, 83' to July, 85'. The results were as follows:1. The most prevalent age group was the 5th decade(35%), and female patient(57.5%) was more comon than male. 2.Angiographic findings were as follows: 1) Multiple aneurysm was found in 8 patients (20%): the one of thesepatients is tripple, the others are double. 2) The location of aneurysm, in order ot frequency, were : ACA andA-com aneurysm in 23 cases(47%). ICA and P-com aneurysm in 17 cases(35%), basilar tip aneurysm in 4 cases(8%), MCAaneurysm in 3 cases(6%) and PCA aneurysm in 1 case(2%). 3) Hydrocephalus was detected in 22 cases (55%): 21 cases(95%) of these cases were demonstarated within the first 3 weeks after attack. 4) Detection of aneurysm itseslfwas 20 cases(50%). 5) Cerebral infarction was 5 cases(12.5%). 6) Subarachnoid enhancement on post-contrast scanwas 8 cases(20%).

Ultrasonography is a very useul diagnostic modality for the evaluation of clinically suspicious abdominalmasses in infants and children, especially in assessing their existence, size,location, origin and internalconsistency. Authors analyzed and present ultrasonographic findings of 92 pathologically and/or clinically provenpediatric abdominal masses that were studied and treated in Chonnam University Hospital during recent 4 years. Theresults were as follows: 1. The most common originating site was kidney(26 cases: 28.3%), followed bygastrointestinal tract (21 cases: 22.8%), genital organ(17 cases: 18.5%), non-renal retroperitoneum (13cases:18.5%), hepatobilary tract (12 cases:13.0%), and anterior abdominal wall (3 cases: 3.3%) in ordre offrequency. 2. The most common mass was hydonephrosis(18 cases: 19.6%). Neuroblastoma(7 cases:7.6%),hepatoblastoma, ovarian teratoma, periappendiceal abscess and abdominal tuberculosis(6 cases: 6.5%, respectively),Wilms tumor(5 cases: 5.4%) were next in order of frequency. 3. The sex distribution is rather similar, that is ,male 42(45.7%) and female 50(54.3%), but characteristically choledochal cyst(2 cases) and genital mass(17 cases)were found only in females. Considering age distribution, 78 cases(84.8%) were found within the range of one to 15years of age. The rest, 14 cases(15.2%), were under the age of one year. 4. With ultrasonography, the diagnosis ofhydronephrosis could be made easily in every case and we could evaluate its severity and level of obstruction withhigh accuracy. 5. All Wilms tumor were large, round or oval, sharply marginated and relatively homogenous solidmasses. 6. All neuroblastomas were irregular shaped, poorly defined, heterogeneous solid masses. Tumorcalcification and extension across the midline were noted in 6 cases(85.7%) and 5 cases(71.4%), respectively. 7.All periappendiceal abscesses had irregular thickened wall and posterior acoustic enhancement: 4 cases (66.7%)among them were mixed echo pattern and 2 cases(33.3%) ehco free. 8. Among the 6 abdominal tuberculoses, 2 wereseen as irregularly defined solid masses, 1 as conglomeration of multiple hypoechoic nodulles and 3 as mixedpatterns. 9. All hepatoblastomas were seen to be poorly marginated solid masses with more echogenicity thanadjacent normal hepatic echo in 5 cases except one. 10. Among the 6 ovarian teraomas, 4 cases were cystic and 2cases solid. Acoutic shadowing was seen in 3 cases. 11. Choledochal cyst (2 cases), hydrops of gallbladder(1cases) and cyst of pancreas head(1 cases) had similar ultrasonic appearance as a large elliptical systic mass,but, it was important in differential diagnosis to ascertain the existence of gallblader and the connectionbetween the cyst and bile duct.

Conventional radiologic methods had given the limited informations about itraabdominal abscesses. Today,however, CT and ultrasongraphy provide detailed anatomic location, number and dimension of intraabdominal abscessand also permit percutaneous placement of catheter large enough to effect drainage. Percutaneous catheter drainageof intraabdominal abscess now offers an alternative to surgery. This simple method of mechanical drainage, whenemployed with systemic antibiotics, can be successful in treating the majority of intraabdominal abscesses.Authors analysed 24 cases of percutaneous abdominal abscess drainage performed at chonnam Natinal UniverstiyHospital from May 1985 to June 1986. The results were as follows: 1. The sites of abscesses; liver in 14cases(58.3%), psoas muscle in 3 cases(12.5%), subphrenic space in 3 cases (12.5%), pelvic cavity in 2 cases(8.3%),perirenal space in 2 cases(8.3%). 2. Complications during or after procedures were minor in the majority of cases.3. Average duration of drainage was as follows: 7.8days in liver abscess, 15.3 days in psoas abscess, 6 days inpelvic abscess, 7 days in subphrenic abscess.
