The effects of hyperbaric oxygen on radiation cystitis have been reported in patients with radiation-induced hemorrhagic cystitis refractory to conventional therapy. Cessation of gross hematuria and reversal of cystoscopic bladder changes were seen in response to a series of hyperbaric oxygen therapy of 3 atmosphere absolute pressure for 2 hours. We report the experience of 2 cases of hyperbaric oxygen therapy for radiation-induced cystitis.

The septum formation(web) of bile duct is an uncommon disease. Its rarity and vague symptoms result in delayed diagnosis. However, the increased use of endoscopic retrograde cholangiopancreatography(ERCP) and percutaneous transhepatic cholangiography(PTC) have resulted in greater awareness of this entity and understanding of its natural history as well as an increased frequency of diagnosis. We have experienced 4 cases of common bile duct web, which were associated with stones in the bile duct, confirmed by operation.

BACKGROUND: Thalium 201(TI-201) has been a widely applied myocardial perfusion agent for the detection of coronary artery disease. however its low emission energy and long half-life make this agent suboptiomal for the examination of coronary artery disease. To circumvent the physical limitation of TI-201, a group of technetium 99m-labeled isonitril complex has been developed. Our study was done to examine the value of SPECT with 99mTc-HexaMIBI in estimating myocardial perfusion in patients with myocardial infarction. METHODS: We evaluated the sensitivity of SPECT with 99mTc-HexaMIBI in 29 patients with acute myocardial infarction. We also compared the severity and vascular territory of abnormal perfusion on SPECT scanning with severity of coronary artery stenosis, values of serum enzyme and sites in ECG. RESULTS: 1) There were 26 patients(90%) who showed perfusion defect, and 3 patients(10%) who showed normal perfusion in myocardial SPECT. The 3 patients with normal perfusion demonstrated non Q-wave infarction of ECG. 2) Among 23 patients performed coronary argiography, there were 19 patients(82%) who showed positive findings on myocardial SPECT and luminal narrowing above 50% on coronary angiogram, and there were 3 patients(13%) who showed significant coronary artery stenosis in spite of negative myocardial SPECT. 3) The grade of perfusion defect showed no significant difference between groups undergone thrombolytic therapy and groups not undergone thrombolytic therapy. 4) There was good correlation between the site of perfusion defect on SPECT and the site of infarction on ECG. CONCLUSION: We conclude that SPECT with 99mTc-HexaMIBI is a promising non invasive test for simultaneous diagnosis of myocardial infarction and evaluation of perfusion defect.

Far lateral disc herniation(FLDH) with compression of the nerve root as it exits through the foramen has been a recognized entity for a number of years. Failure to diagonose and precisely localize these herniations can lead to unsuccessful surgical exploration or exploration of the innocent interspace. If these herniation are diagnosed, they often cannot be adequately exposed by the classic minline hemilaminectomy approach. A partial or complete unilateral facetectomy to expose these herniations can lead to vertebral instability or contribute to continued postoperative back pain. The authors present 5 patients who were diagnosed as having far lateral lumbar disc herniations from 1988 to 1990. Two of these were at L4-5 level, two at L5-S1 level and one at L3-4 level and all were over 60 years old. High resolution CT scan appeared to be the best study and the paramedian muscle splitting microsurgical approach, done in 3 cases, was found to be the most direct and favorable anatomical route to FLDH for vertebral stability and minimal postoperative back pain.

Anterior cervical discectomy and fusion (ACDF) is currently the standard treatment for cervical disc disease. Some patients wish to be treated with a less invasive method, because of their social/physical situations. Here we present one method of treatments for socially/physically active patients. Three patients had triceps weakness and mild posterior neck pain. The offending lesions were at the C6-7 level. All were middle-aged soldiers with families. If conventional ACDF were performed, they would have to retire from the military according to the regulation. They had to be able to perform military drills after the treatment if they were going to be able to keep their jobs. Because of their social/physical situations, all wanted to choose method with that they could treat the disease and keep their jobs. For these reasons, the posterior cervical endoscopic discectomies were performed. Ruptured fragments were successfully removed in all. The arm pain improved by more than 90% in two patients by 7 days and in the other patient by 2 months, respectively (excellent outcome by Macnab's criteria). None of the operations caused instability. All of the patients are currently able to successfully perform their military drills without difficulty. The posterior cervical endoscopic discectomy may be a promising alternative for the physically/socially active patients.

OBJECTIVE: Cervical carcinoma of the uterus, the most common maliganacy among women in Korea, which its etiology and pathogenesis are not yet determined. Recently, since it has been found about the function of the growth factor and its receptor, involved in the regulation of cellular growth and differentiation, many studies have been undertaken about the role of growth factors and its receptors in the growth and differentiation of the tumor cell. METHODS: In this study, we examined the expression of EGFR, TGF-alpha and Ki-67 in 50 CINs and 20 invasive cervical cancers using immunohistochemical stain. RESULTS: Positive rate of EGFR was 92% in CIN, 80% in invasive cancer, negative rate of TGF-alpha was 74% in CIN, 80% in invasive cancer and Ki-67 labelling index(LI) in normal basal cell, CIN I-II, CIN III were 5+/-0.7, 13+/-2.5, 65+/-5.4 repectively and in invasive cancer, LI was over 90. from this result as cervical carcinoma progresses, the expression of EGFR and Ki-67 increase while that of TGF-alpha decreases. CONCLUSION: As cervical carcinoma progress, the expression of EGFR and Ki-67 increase while that of TGF-alpha decreases. Further studies on the expression of EGFR and TGF-alpha and its growth-stimulation mechanism in cervical carcinoma are warranted to establish the pathogenesis of the cervical carcinoma.

To evaluation effectiveness of internal anastomosis and facial-hypoglossal anastomosis the medical records of 29 patients with facial nerve injury in the course of operation for acoustic neurinoma were reviewed. In 8 patients, the interrupted facial nerves were anastomosed at the end of tumor operation, and facial-hypoglossal anastomoses were performed in 20 patients. One patient underwent facial-hypoglossal anastomosis 6 months after internal anastomosis. All the patients had been treated from January 1983 to March 1993 and were followed up for more than 1 year. After primary internal anastomoses, 7 patients resulted in symmetric face at rest and only one failed to show improvement of facial muscle tone. The mean time to the first evidence of facial reinnervation was 5.3 months. In 20 patients with facial-hypoglossal anastomosis, improvement of facial muscle tone was demonstrated in 19 patients and in one patient there was no improvement. Thirteen cases(68%) showed facial symmetry at rest and 5 of them could close their eyes completely. The first evidence of reinnervation was noted between 3 and 12 months after anastomosis with a mean of 6.3 months. The anastomoses were performed between 8 days and 22 months after injury of the facial nerve, and the time to reinnervation after anastomosis was significantly influenced by the duration of nerve injury(P=0.0439). Primary internal anastomosis revealed better recovery of facial muscle function compared with facial-hypoglossal anastomosis(P=0.0299).

For the experimental study of neural tube defect (NTD), a surgical model has advantages over other models in a few aspects. It causes less functional derangement of cells and the NTDs can be made selectively by surgery. The authors planned to use the surgical model for the experimental study of NTD. As the first step for the studies, the chronological changes of morphology during the early postoperative period were investigated using postincubation 3-day chick embryos. The objectives of this study are (1) the morphological evaluation of the surgical model as a method for studies of open NTD, and (2) the observation of morphological changes for the first 24 hours after surgery which include 'overgrowth' appearance and the continuity between the surface ectoderm and the neuroectoderm. The morphological changes were observed by light microscope and scanning electron microscope. Immediately after surgery, typical open NTDs were observed. Morphologically they were very similar to the appearance of spontaneous (non-surgical) open NTDs. The opened neural tubes were everted progressively and they looked rather flat at 24 hours after surgery. Cellular hyperplasia ('overgrowth' appearance) was noted within 24 hours after surgery and became more prominent during the 24 hours. There was increasing continuity between the surface ectoderm and the neural tissue until 24 hours after surgery when the continuity looked almost complete. In conclusion, surgically induced NTDs are morphologically very similar to spontaneous NTDs.(ABSTRACT TRUNCATED AT 250 WORDS)
