Korean Journal of Urology 1982;23(5):617-621
A clinical study was made on 52 patients (55 organs) with renal injuries in Capital Armed Forces General Hospital during the period from January, 1980 to May, 1982. Emphasis was placed on comparison of the expectant and early surgical management. Following results were obtained: 1. The nonpenetrating injuries were 45 cases (86.5%), penetrating, 7 cases (13.5%) and the most common cause of nonpenetrating injuries was traffic accident in 23 cases (44.2%) and the most common cause of penetrating injuries was gunshot in 6 cases (11.6%). 2. As to the management of nonpenetrating injuries, the expectant management was performed in 32 cases (71.1%) and early surgical management in 13 cases (28.9%). 3. All cases of penetrating injuries were managed with early surgical intervention. 4. As to the early surgical management in nonpenetrating injuries, nephrectomy was performed in 6 cases (46.2%), simple closure in 6 cases (46.2%) and partial nephrectomy in I case. 5. As to the early surgical management in penetrating injuries, nephrectomy was performed in 5 cases (71.4%), simple closure in 1 case and partial nephrectomy in I case. 6. In group of expectant management, gross hematuria disappeared at 2.7 days on an average. 7. In nonpenetrating injuries, complication were 6 cases (18.8%) after expectant management, while none, after early surgical management. 8. In penetrating injuries, complication were 2 cases (28.6%) after early surgical management. 9 As to the management of complication in nonpenetrating injuries, nephrectomy was performed in 4 cases (66.7%), deroofing of cyst in 1 case and expectant management in 1 case. 10. As to the management of complication in penetrating injuries, incision and drainage was performed in 1 case and colostomy in 1 case.

The authors report a case of thoracic outlet syndrome in left side. Thoracic outlet syndrome is a collective term in which symptoms and signs are due to bony and soft tissue compression of the neurovascular bundle at the thoracic outlet. It is a rare case in neurosurgical field. So we had experienced one case of thoracic outlet syndrome which was improved by transaxillary approach for resection of first rib. The clinical features, diagnostic test, radiological findings, and operative technique are presented with review of literatures.

We have expressed GFP in Sf9 and Bm5 cells or Bombyx by larvae by using Ac-Bm hybrid virus capable of replicating in both Bm5 and Sf9 cells. Genomic DNA of Ac-Bm hybrid virus expressing P-galactosidase was cotransfected with baculovirus transfer vector containing GFP gene, pBacPAK-GFP in Sf9 cells. The Ac-Bm hybrid virus harboring GFP was named as Ac-Bm hybrid virus-GFP. The Ac-Bm hybrid virus-GFP-infected insect cells were easily selected by detecting the emission of GFP from each well of cell culture dish on the UV illuminator. GFP produced by Ac-Bm hybrid virus-GFP in Sf9 and Bm5 cells or B. mori larvae was confirmed by SDS-PAGE and Western blot analysis using GFP antibody. In addition, B. mori larvae infected with Ac-Bm hybrid virus-GFP was apparently appeared fluorescence from the whole body at 5 days postinoculation. The fluorescence of GFP from the hemolymph and fat body of B. mori larvae infected with Ac-Bm hybrid virus-GFP was also observed by fluorescence microscope. In conclusion, our results demonstrated that in baculovirus expression vector system, use of Ac-Bm hybrid virus have an additional advantage of expanded host range for producing recombinant proteins.

BACKGROUND: Diverticulosis of the cecum and ascending colon is a rare disease in Western countries, it is more common in the Orient. Making the diagnosis preoperatively could be difficult, and the intraoperative assessment and decision of optimal treatments are difficult. METHODS: Therefore, we reviewed the patient's charts of diverticulosis of the cecum and ascending colon at our hospital from 1992 to 1997. RESULTS: During the past 5 years, a total of 53 cases of diverticulosis of the cecum and ascending colon had been treated at this hospital. Mean age was 41.8 years (range 20-70). The male to female ratio was 1.8 : 1. Frequent complaints were abdominal pain (46 cases, 86.8%), followed by diarrhea (5 cases, 9.3%), indigestion (4 cases, 7.5%), and bowel habits change (2 cases, 3.8%). Mean duration of illness was 3.5 days(range 24 hours~15 days). In non-surgical cases, diagnoses were established with barium enema, CT scan, or ultrasonography. The accuracy of these methods was 91%, 75%, and 25%. In surgical cases, the preoperative diagnoses were appendicitis(13 cases, 50.1%), diverticulitis (7 cases, 31.8%), and abscess (2 cases, 9.1%). Treatments of the cecum and ascending colon diverticulitis were conservative management (3 teases,58.5%) and surgical treatment (22 cases,41.5%). The operative procedures were right hemicolectomies (2 cases), ileocecal resections (2 cases), diverticulectomies (6 cases) and appendectomies only (11 cases). CONCLUSION: These results suggest that correct diagnosis of the diverticulitis of the cecum and ascending colon made before treatment is very important because correct assessment of diverticulitis intraoperatively is difacut. Liberal use of diagnostic modalities could facilitate to make correct diagnosis to set a proper plan for treatment.

The authors report a patient with a small traumatic cirsoid aneurysm of the scalp, diagnosed by duplex doppler ultrasonography. This 15-year-old boy was diagnosed as a cirsoid aneurysm by duplex doppler ultrasonogram which revealed an ovoid cystic lesion at left temporal area of scalp containing vascular flow mapping. The gross appearance showed an aneurysm with arteriovenous fistula, consisting of two feeding arteries and two draining veins. Total removal of mass was made and the histological examination revealed an aneurysm which showing irregular contour of inner surface and thickened fibrotic vascular wall without normal arterial layers. Noninvasive duplex doppler ultrasonography before surgical excision or direct puncture embolization of cirsoid aneurysms of the scalp could be recommended as an alternative management option.

Journal of Cerebrovascular and Endovascular Neurosurgery 2022;24(4):335-340
Objective:
Digital subtraction angiography (DSA) is an imaging technique used to diagnose and confirm abnormal lesions of cerebral blood vessels in various situations. Several complications such as cerebral infarction, contrast-induced allergy, and angio-site hematoma or infection can occur after DSA. We investigated complication rates and risk factors related to DSA.
Methods:
All patients who underwent DSA at Incheon St. Mary’s Hospital from January to December 2021 were included. Those who underwent emergency DSA due to stroke or who underwent endovascular surgery within 1 week after DSA were excluded. Complications that occurred within 1 week after DSA were included in the study and was classified into three categories (neurologic complications, contrast-induced allergy, and wound complications).
Results:
The mean age was 57.7±13.2 years old and the female was dominant at 63.9%. The overall complication rate was 5% (n=20/407). Regarding neurologic complications, the presence of malignancy (p<0.01), and a longer procedure time (>15 minutes, p=0.04) were statistically significant factors. Contrast-induced allergy did not show any statistically significant difference in any parameter. The wound complication rate was higher in men (p=0.02), trans-femoral approach (p=0.02), frequent alcohol drinkers (p=0.04), those taking anticoagulants (p=0.03), and longer procedure time (>15 minutes, p<0.01).
Conclusions
DSA is an invasive diagnostic modality and can cause several complications. Patients with cancer should be more careful about the occurrence of cerebral infarction, and men taking anticoagulants or drinking frequently should be more careful about the occurrence of angio-site hematomas.

Cysticercosis is the most common parasitic infection affecting the central nervous system. Spinal neurocysticercosis (NCC) is very rare compared with intracranial NCC and requires more aggressive management because these lesions are poorly tolerated. The authors report a case of intradural extramedullary cysticercosis of the entire level of spine with review of the literature.

OBJECTIVES: Copper and Zinc, the trace elements of a living body, take a part in immunologic mechanism and induce the pulmonary fibrosis which is the pathologic progress of pneumoconiosis. This study was performed to assist the identification of the pathologic process of pulmonary fibrosis in pneumoconiosis. METHODS: The subjects of this study was 200 diagnosed persons as pneumoconiosis, of whom 100 persons was the visitors in the outpatients departments of pneumoconiosis and 100 admissive pneumoconiosis patients. The serum copper and zinc are measured and com pared. RESULTS: The mean serum copper concentration of visitor group was significantly higher than that of control group, and that of stage V3 subgroup of visitor group was highest because of their advanced fibrosis. But, there was not the difference of serum copper concentration between patient and control group. We thought that the reason was poor nutritional and health status of the patient. The mean of serum zinc concentration of visitor and patient control was lower than that of control group. As the degree of pulmonary fibrosis was more severe from stage Vl, V2, V3 of visitor to stage Pl, P2, P3 of patient, the mean of serum zinc concentration was lower. The ratio of serum copper/zinc of visitor and patient was higher than that of control, and that of patient was higher than that of visitor. Those results showed that the ratio of serum copper/zinc ratio more greatly expressed the degree of progression of pneumoconiosis than only copper or zinc concentration by adjustment of nutritional and health status of the patient. CONCLUSIONS: As above study results, the degree of pulmonary fibrosis of pneumoconiosis could be estimated by means of serum copper/zinc ratio.

Although the incidence of intracranial multiple aneurysms are not low, the occurrence of multiple aneurysms more than three developing on the ipsilateral carotid artery is quite rare. We present a patient with five aneurysms on the left internal carotid artery. Four aneurysms arising from the left internal carotid artery underwent microsurgical clipping and wrapping, and remnant superior hypophyseal artery aneurysm was treated by using coil embolization. Incidence and risk factors for management of multiple aneurysms were investigated with the literature review.
