PURPOSE: Vascular endothelial growth factor (VEGF) is a potent angiogenic factor in a number of cancers. The aim of this study was to evaluate the clinical significance of the serum level of VEGF in hepatocellular carcinoma (HCC) patients. METHODS: Serum VEGF was measured by an enzyme linked immunosorbent assay (ELISA) method. The correlation between serum VEGF level and clinico-pathological data of HCC patients were evaluated. RESULTS: The serum VEGF levels significantly increased with increasing tumor size and platelets count. The mean serum VEGF level in HCC patients with microvessel tumor invasion was higher than in those without microvessel tumor invasion. CONCLUSION: A high serum VEGF level may be an indicator of tumor progression and an important predictor of microvessel tumor invasion.

Multiple cerebral arteriovenous malformations(AVMs) are thought to be rare lesions. The authors present a case of multiple AVMs in te left cerebral hemisphere. A 26-year-old male patient came to the hospital for evaluation of recurrent attacks of generalizd seizures. Cerebral angiography demonstrated two separated AVMs having different feeders and drain veins in the left cerebral hemisphere. Using staged operations we excised the lesions completely. The criteria and surgical tactics of multiple AVMs are discussed with a review of the literature.

Vasectomy is one of the most common forms of male contraception throughout the world. However, more vasectomy reversals are sought each year because of the increasing number of second marriages and other causes. Before recommending vasectomy, urologists may wish to resolve in their own mind the conflict between reports that maintain the testis is harmed by vasectomy and those that slate is not. We studied a group of patients undergoing vasectomy reversal to determine whether histopathologic change on light and electron microscopy would be detected. Only one testis specimen from post-vasectomy patients showed an abnormality correlated with spermatogenesis and five cases showed mild focal interstitial fibrosis without abnormality of spermatogenesis on light and electron microscopy. We found that vasectomy has some influence to the spermatogenesis and pathologic change.

Stamey endoscopic suspension of bladder neck is a reliable technique among various surgical techniques with high success rate and little morbidity. We treated 8 patients complaining of urinary incontinence with Stamey operation from February 1988 to May 1990 and Follow-up for over 6 months. The results as follows; 1. Patients varied in age from 31 to 63 (mean;45) years. All patients were multiparous average 2.87 (2-4) times of previous deliveries 2. All patients showed frequency and nocturia. Severities of incontinence were Grade I in2 patients, Grade II in 5, Grade III in 1 3. No significant changes were identified between preoperative and postoperative urethral pressure profiles. 4. On preoperative lateral cystourethrograms, bladder base was descended about -2.10+-0.74cm from SCIPP line and elevated about +1.2 cm+/-0.49 cm from SCIPP line on postoperative lateral cystourethrograms. 5. Incontinence was disappeared in 7 patients, but 1 patients was recurred due to rupture of suture material during lifting heavy material.

Foramen magnum tumors are uncommon. We experienced two cases of foramen magnum tumor. One case was meningioma, the other neurinoma. Metrizamide computerized tomography scanning and pantopaque myelography have been the radiographic test most commonly used to evaluate the foramen magnum. Moth cases underwent suboccipital craniectomy and total laminectomy in C1 & C2 with total removal of tumor mass. Postoperatively, both cases showed improvement without neurological sequelae. Both cases are discussed, and a review of literature is presented.

The pneumoretroperitoneum has many etiologies. These range from the clinically insignificant to the potentially fatal, if not recognized promptly. Spontaneous pneumoretroperitoneum can develope from ulcerative colitis, colonic diverti-culitis, or duodenal ulcer perforation. It can be associated with pneumothorax, pneumomediastinum, respiratoy tract rupture, etc. An isolated pneumoretroperitoneum are a more obscure symptom than a pneumoperitoneum. Mostly, the diagnosis of retroperitoneal air depends of radiologic methods, such as simple X-ray, ultrasound (US), or computerized tomography (CT) measurements. In this case, we diagnosed a pneumoretroperitoneum from CT and found that it caused the perforation of the colon spontaneously, without any underlying diseases, due to chronic constipation without underlying diseases

A clinical observation was made on 64 cases of the bladder rupture who were admitted to our hospital during the period from June, 1979 to February, 1991. The results are as following ; 1. Of 355 cases of the genitourinary tract injury, the bladder rupture were 64 cases (18.0%), which were composed of 40 cases (62.5%) of bladder rupture without pelvic bone fracture and 24 cases (37.5%) of bladder rupture with pelvic bone fracture. The bladder rupture without pelvic bone fracture were composed of 35 cases (87.5%) with intraperitoneal bladder rupture and 5 cases (12.5%) with extraperitoneal bladder rupture, the bladder rupture with pelvic bone fracture were composed of 13 cases (12.5%) with intra and extraperitoneal bladder rupture. 2. In 24 patients with pelvic bone fracture, the most common site of bladder ruptures were found on the lateral wall in 12 cases (50%), and followed by the dome in 9 cases (37.5%), multiple areas in 3 cases (12.5%). In 40 patients without pelvic bone fracture, the most common site of bladder ruptures were found on the dome in 33 cases (82.5%), and followed by the multiple areas in 4 cases (10%), lateral wall in 3 cases (7.5%). 3. The average size of the bladder rupture was 6.5cm in cases without pelvic bone fracture, 6. 8cm in cases with pelvic bone fracture, especially comminuted pelvic ring fracture had most severed bladder rupture (average; 8.3cm). 4. Of 24 pelvic bone fractures, pubic rami fractures were most common (41.6%), and followed by comminuted pelvic ring fracture (25%), anterior and posterior pelvic ring fractures (12.5%), acetabulum and isolated fractures (8.3%), symphyseal separation fractures (4.1%) in order of frequency. 5. 5 cases (20%) of pelvic bone fractures were associated with posterior urethral injury, especially 60% in The pubic rami fracture. There was no significant relation between the type of pelvic fracture and the type of bladder rupture, but the fractures involving pubic arch were more often associated with posterior urethral injury.

Background: Korea is no longer safe from the risk of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL); the first reported case was a Korean woman in her 40s who had a 7-year-history of receiving an implant-based augmentation mammaplasty using a textured implant. We conducted this study to discuss the emerging crisis of stakeholders in implant-based augmentation mammaplasty and to propose a multi-disciplinary approach to early detection of its complications. Methods: We analyzed medical examination data that was collected from patients who visited us between August 12 and September 27, 2019. We evaluated a total of 114 women (n = 114) in the current study. They were evaluated for whether they were in healthy condition. Moreover, their baseline characteristics were also examined; these included age, gender, height (cm), weight (kg), duration since surgery (years), possession of a breast implant card, the site of surgical incision, side of symptoms and reasons for outpatient visit. Furthermore, the patients were also evaluated for their subjective awareness of the manufacturer, surface and shape of the breast implant. Potential complications include malrotation, folding, seroma, capsule thickening, upside-down rotation, rupture, capsule mass and breast mass. Results: A majority of the patients had a past history of receiving textured implants. The corresponding percentage was 78.95% (90/114) and 85.09% (97/114) based on their subjective awareness of a breast implant and sonographic findings, respectively. That is, it was slightly increased with the use of a breast ultrasound. Conclusion Here, we propose the following approaches. First, patient data should be prospectively collected. By tracking outcomes and complications of an implant-based augmentation mammaplasty, both high-quality care and patient safety can be ensured. Second, stakeholders in implant-based augmentation mammaplasty should collaborate with customers and regulatory authorities. Third, surgeons should consider applying imaging modalities for early detection of postoperative complications.
