Perigraft seroma is uncommon complication of polytetrafluoroethylene(PTFE) grafts applied as an arteriovenous shunt for hemodialysis. It is a collection of clear, sterile fluid confined to nonsecretory fibrous pseudomembrane, most commonly localized around the middle and distal portion of graft. The possible etiologic factors of perigraft seroma include poor graft incorporation, mechanical graft damage caused by alcohol and povidone-iodine, intraoperative streching of the graft, variations in quality control at the time of manufacture and contributing factors such as anemia and coagulopathy in uremia. The best strategy for management of perigraft seroma is not clear. spiration or drainage alone is not effective, and some authors advocate graft removal. We report a case of perigraft seroma around arterial end of PTFE graft along with a brief review of the literatures.

PURPOSE: Febrile convulsions (FC) were considered to be a benign seizure syndrome that is distinct from epilepsy. But it is thought that children with complex features i.e., partial or prolonged seizures or multiple episodes of FC would bear a higher risk of developing unprovoked seizures. The aim of this study is to look into the relative significance of each criteria that define complex febrile convulsions (CFC) as a predictor of subsequent epilepsy. METHODS: All children were retrospectively identified for a febrile seizure through pediatric departments of the Konyang University Hospital. Information was collected from medical records and interviews with parents. Patients with abnormal neurological examinations at presentation were excluded. RESULTS: This study was performed from March 2000 to December 2003. Sixty-three out of 314 children (20.0%) with febrile convulsion fulfilled the criteria for CFC and forty-four children of them have been followed for 12 months or more. Ten of these (23.2%) had unprovoked seizures for 14-62 months (median 34.2+/-11.6 months). The patients with partial FC showed a trend toward a higher risk (57.1%) of developing epilepsy than the patients with multiple or prolonged febrile convulsions (26.7%, 24.1% respectively). CONCLUSION: We found that the partial feature of febrile convulsion is associated with subsequent epilepsy.

OBJECTIVE: To compare clinical features and surgical outcomes of laparoscopic-assisted vaginal hysterectomy (LAVH) by the number of ports in the treatment of uterine myoma and adenomyosis. METHODS: Between 1st January 2009 and 31th March 2010, 50 patients underwent 5 mm-2 port LAVH and 10 mm-3 port LAVH respectively by same surgeon at Chosun university hospital. We compared clinical features and surgical outcomes. RESULTS: There was no difference in weight of uterus between the 5 mm-2 port LAVH group and the 10 mm-3 port LAVH group (465.2+/-206.9 g vs. 470.8+/-148.5 g) (Mean+/-S.D.), and in amounts of blood loss during procedure between the two groups (115.0+/-179.3 mL vs. 125.0+/-211.7 mL). The duration of procedure showed a difference between the two groups(55.1+/-12.0 minutes vs. 60.4+/-19.5 minutes) (p=0.03). In the 5 mm-2 port LAVH group, 2 of 50 (4%) converted to laparotomy, and 1 of 50 (2%) in the 10 mm-3 port LAVH group. There was no difference in length of postoperative hospital day between the two groups (5.8+/-1.0 days vs. 6.3+/-1.6 days). In the comparison of postoperative complications, 1 of 50 (2%) required readmission and reoperation for both of the two groups. CONCLUSION: We conclude that 5 mm-2 port LAVH could be a available method in the treatment of uterine myoma and adenomyosis.

OBJECTIVE: To compare clinical features of minilaparoscopic radiofrequency myolysis (MLRFM) with laparoscopic-assisted vaginal hysterectomy (LAVH) in the treatment of uterine myoma. METHODS: Between 1st January 2006 and 31th March 2009, 125 patients underwent LAVH and 125 patients underwent MLRFM by same surgeon at the University of Chosun Hospital, Department of Gynecology. We compared the age of patients, indication for treatment, myoma size, major symptom, duration of procedure, amounts of blood loss and postoperative transfusion, length of hospital day, postoperative complication and satisfaction between the two groups. RESULTS: There were significant differences in duration of procedure between the LAVH group and the MLRFM group (69.0+/-31.6 minutes vs 43.5+/-19.8 minutes) and in the amounts of blood loss during procedure (215.2+/-215.0 mL vs 0.8+/-8.9 mL). The amounts of postoperative transfusion was 0.3+/-0.7 pints, 16 of the 125 (12.8%) for the LAVH group and no one underwent postoperative transfusion for the MLRFM group. There was significant difference in length of postoperative hospital day between the LAVH group and the MLRFM group (5.0+/-1.2 days vs 2.3+/-1.2 days). In the comparison of postoperative complications, there was no significant complication for the LAVH group, but there was major complications requiring readmission and reoperation for the MLRFM group. In MLRFM group, postoperative myoma size decreased compared to preoperative size. CONCLUSION: We conclude that there was no treatment of choice in uterine myoma. When considering treatment of uterine myoma, we should choose appropriate method after analyzing patient characteristics, general condition, uterine myoma characteristics case by case.

5.Adiposity Rebound Timing in Small for Gestational Age Children Treated With Growth Hormone: Results From LG Growth Study Data

Journal of Korean Medical Science 2025;40(4):e12-
Background:
Adiposity rebound (AR) refers to the period during growth when the body mass index reaches its lowest point before increasing again. The timing of AR is associated with the development of obesity and puberty onset. Although studies have evaluated AR timing in Korean children, none has focused on children born small for gestational age (SGA).
Methods:
This study analyzed data from a multicenter observational clinical trial (LG Growth Study) to determine AR timing in children born SGA without catch-up growth (CUG) who were treated with growth hormone (GH) therapy. The study also aimed to identify factors associated with AR timing, examine the influence of AR timing on puberty onset, and assess the effectiveness of GH therapy.
Results:
A total of 151 children born SGA without CUG were included. Of them, 15% experienced AR between 4 and 5 years of age, 42% between 5 and 6 years, 27% between 6 and 7 years, and 16% after 7 years of age. A significant positive correlation was noted between the height standard deviation score at the start of treatment and AR timing. However, no significant correlation was observed between AR timing and puberty onset or the effectiveness of GH therapy.
Conclusion
This study provides insights into AR timing in prepubertal children who meet the specific SGA criteria and its relationship with growth outcomes. The findings suggest that AR in children born SGA who do not experience CUG occurs later than in the general population, with no significant relationship between AR timing and puberty onset or growth outcomes.

An epidermal cyst, presenting as an intrascrotal tumor, with no relation to the testicles or cord structures, is a rare benign tumor. Their etiology is unknown, but the most widely accepted theory on the histogenesis of testicular epidermal cysts is that they are the end result of a monolayer teratoma arising from germ cells; however, an extratesticular epidermoid cyst is believed to be an abnormal closure of the median raphe and urethral groove. An extratesticular epidermal cyst is normally subcutaneous, and can be localized anywhere along the median raphe, from the distal penis to the anus. To our knowledge, there has been no case reported in the Korean literature. A case of an intrascrotal epidermal cyst is reported in a 44-year-old man.

Herein, a new left renal vein stenting procedure (expandable metallic stent placement), which provided relief for an 18-year-old man incapacitated by an intermittent gross hematuria, is reported. The placement of an expandable metallic stent is a minimally invasive therapy, and a simpler and more physiological therapy than previous approaches to Nutcracker syndrome.
