1.Prevention and treatment of post-prostatectomy incontinence
China Oncology 2014;(3):231-234
Postoperative incontinence is one of the most feared complications of radical prostatectomy with a major impact on patients’ quality of life. There are several ways to treat with the incontinence including pelvic lfoor muscle training and medication as the conservative treatment, nerve-sparing approach during the operation and the urethral sling and the artificial urinary sphincter placement as the operative treatment. The aim of this article is to evaluate the treatment stated above to provide some guidance to deal with post-prostatectomy incontinence.

Skin wart is an infectious disease of human papillomavirus(HPV). Its clinical and histopathologic characteristics are largely determined by lesion sties, viral type and host immunity. The infected basal cells and keratinocytes of the epidermis are induced to proliferate by the viral genome. It is, however, not well known how htose factors give rise to histopathologic alterations in the infected basal cells and keratinocytes. So, evaluation of correlation between HPV antigen expression in the wart tissues and clinical and histopathologic charateristics was done on 83 cases of skin warts. The age of patients ranged from 2 to 83 years. Thirty six(43.3%) cases were diagnosed before the age of third decade. The sex ratio was nearly same. Verruca vulgaris was most common(46 cases), followed by verruca plana(26 cases) and verruca palmoplantaris(11 cases). HPV antigen expression was observed in 43 out of total 83(51.8%). It was noted in 47.8%(22/46) of verruca vulgaris, in 46.2%(12/26) of verruca plana and in 81.8%(9/11) of verruca palmoplantaris. HPV antigen-positive groups included more younger patient's age and more higher PCNA than those of HPV negative groups. HPV positive groups also tend to have shorter duration of disease and more numerous mitoses than HPV negative groups. HPV antigen-positive groups showed lower inflammation grade than that of HPV negative groups(p<0.05). The higher the inflammaton grade is, the lower the HPV antigen expression rate. In summary, HPV antigen expression in cutaneous wart tissue is significantly correlated with the proliferative activity of the lesion. It is also significantly correlated with the inflammation that is considered to be the result of cell-mediated immune reaction.

3.Idiopathic Intestinal Lymphangiectasia.
Korean Journal of Pathology 1994;28(3):319-321
This is a case report of idiopathic intestinal lymphangiectasia occurring in a 3-year-old boy. Idiopathic intestinal lymphangiectasia is believed to be a part of the generalized congenital disorder of lymphatic system. The present case revealed markedly ectatic lymphatics in the lamina propria of duodenal villi with lymphorrhagia. Clinical features were typical of the protein-losing enteropathy; hypoalbuminemia, hypocalcemia, chylous ascites, edema of the lower extremities and mild lymphocytopenia. This case indicates that serious protein loss may ensue, even in cases of intestinal lymphangiectasia without abnormalities of extraintestinal lymphatics.

6.An Experimental Study of the Effect of Bone Cement upon the Epiphyseal Plate of Growing Rabbits
The Journal of the Korean Orthopaedic Association 1979;14(2):309-313
Acrylic bone cement is now widely used in surgery for many purposes. Therefore, the effect of bone cement on the growth plate of a growing bone may be an interesting subject, particularly in the orthopedic field. The authors carried out an experiment to study the effect of bone cement on the growth plate of the bone, using 32 growing rabbits weighing from 800 to 1000 gm, which were divided into 2 main groups. In Group I, which was the control group, the growth plates were injured mechanically by inserting a Kirschner wire and a stainless screw, 1.5 mm and 2.5 mm in diameter, respectively, which were then removed. In Group II, the growth plates were also injured by the same method as in Group I, and bone cement was inserted into the holes made by the insertion of the Kirschner wire and the screw. Then the histological findings of the injured plates were studied at 2, 4, 6 and 10 weeks after injury. Following observations were made. 1. In Group I, in which the growth plates were only mechanically damaged, the histologic changes were localized only in that portion of the plate which had been injured by a wire or a screw, leaving the rest of the plate relatively normal. In Group II, the extent and severity of the injury were more wide and severe. 2. Proliferation of mesenchymal fibroblasts and deformity of the growth plate were more severe in Group II. 3. In both groups the extent and severity of growth plate injury were more marked when injured by a screw.

Nerve root compression due to ligamentum flavum hematoma is extremely rare, with less than 70
cases reported in the literature. The clinical presentation and images were similar to those of spinal
epidural tumors. Herein, we reported a previously healthy 64-year-old female who presented with
right radicular leg pain. Neurological examination was consistent with right L5 root compression.
The magnetic resonance imaging revealed a mass posterior to the L5 thecal sac, appearing as high
intensity on T1-weighted and T2-weighted images. During operation, the dark hematoma within the
ligamentum flavum was found. The pathological examination confirmed the diagnosis of hemorrhage.
Her prognosis following surgery was excellent.

Seidel nail is one of locked humeral nail and Seidel himself reported excellent result in his preliminary report using his nail. But our early experience showed disappointing result with high rate of complications, So we reviewed our 16 cases of humeral shaft fracture with polytrauma treated with Seidel nail and studied anatomical fitness of the nail within the distal medullary space using CT scan. The most frequent complication was intraoperative fracture of the proximal humerus < 4 cases> and this seemed to be due to lateral placement of pilot hole. There were 3 cases of nonunion and these cases showed insufficient distal anchorage, either primarily or postoperatively. Anatomical fitness study showed insufficient spreading of nail flanges in 5 cases of distal canal width below 9mm and nonunion cases were in this group. Other problems of Seidel nail were technical difficulties due to occasionally incorrect proximal targeting device and frequent breakage of adaptor screw. Study of more cases may be needed to confirm the design problem of Seidel nail.

Experimental studies suggest that captopril plays an important preventive role in radiation induced renal injury (RRI). To elucidate the pathogenesis of RRI and effect of captopril, one subgroup was irradiated with a single dose of 9 gray (Gy) total body irradiation and another subgroup with 17 Gy local irradiation in the right kidney. Twenty-four healthy looking Sprague-Dawley rats, weighing 200~250 g, were divided into one control and three experimental group (EG)s for this study. The control group, composed of 2 rats, was maintained on stock diet and drinking tap water. EG was divided into three. EG 1 composed of two subgroups, the first subgroup, 3 rats each, was sacrificed within 12 hours after 9 Gy and 17 Gy single dose irradiation only and the second subgroup, 2 and 1 rats each, was sacrificed 8 weeks after the same doses irradiation. EG 2 composed of subgroups of 2 and 3 rats was given 500 mg/L of captopril in the drinking water after irradiating them with 9 Gy and 17 Gy and sacrificed in the 8th week. EG 3 was subdivided into four subgroups by captopril doses given, 62.5 mg/L, 125 mg/L and 250 mg/L and sacrificed 20 weeks after 9 Gy and 17 Gy irradiation. On light microscopy proximal convoluted tubules showed cytoplasmic vacuolization and focal necrosis in the subcapsular region in EG 1 sacrificed within 12 hours after 9 Gy and 17 Gy irradiation only (sham) and very mild fibrosis in juxtamedullary regions in rats sacrificed 8 weeks after irradiation. In EG 3 these changes were severely increased with additional increased fibrosis in the juxtamedullary region in the group given captopril 62.5 mg/L. On transmission electron microscopy, there were various degenerative changes of organelle. Among the captopril administered EG 2 and EG 3, rats given a high dosage revealed milder degree of damage compared to that of rats given a low dosage, and thickening of basement membrane was remarkable in rats given a low dosage. There was a reduction in tubular damage related to the captopril dosage. According to the above findings, administration of a high dose of captopril might preserve the ultrastructure in RRI and the possible mechanism of captopril was discussed.

A study on branching patterns of middle hepatic artery was performed in 109 patients with A-P and oblique view hepatic angiogram, which refered to size and location of quadrate lobe in CT and SMA portography We could analyze the branching patterns of middle hepatic artery (MHA) in 100 among the 109 patients. MHA arising as a first branch of left hepatic artery was the most common pattern (50%), and MHA arising from proper hepatic artery separately one from left hepatic artery was the next common pattern (35%). MHA originating from left gastric artery, or from anterior or posterior of the right hepatic artery was seen. MHA WAS not found as an accessory or replaced artery except as replaced common hepatic artery.
