PURPOSE: To analyse the risk factors for recurrence of hemangiomas in extremities after surgical treatment and to compare with those of trunk. MATERIALS AND METHODS: 120 cases of hemangioma with surgical treatments from June 1998 to September 2009 were analysed. 53 cases with surgical treatment on trunk in the same period were set to be the control group. We analyze several factors: age, location, site, size, histologic types and correlation between recurrence and each risk factor using logistic regression analysis. RESULTS: Recurrence rate was 11.7% in extremities and 9.4% in trunk. There were no correlation between recurrence and age, site, size, histologic type. But, there was stastically significant correlation between recurrence rate and location, especially hand, forearm, feet in extremities and head and neck in trunk. CONCLUSION: Recurrence after surgical treatment of hemangioma is highly prevalent in anatomical location such as, hand, foot and forearm those are difficult to achieve complete resection because of close to neurovascular structures. Careful observation should be needed owing to incomplete resection can occurs recurrence.

OBJECTIVE:To evaluate the biodurability of the covering material in retrievable metallic stents covered with polycarbonate polyurethane. MATERIALS AND METHODS: Using a peristaltic pump at a constant rate of 1ml/min, bile was recirculated from a reservoir through a long tube containing four stents. Each of these was removed from the system every two weeks and a radial tensile strength test and scanning electron microscopy (SEM) were performed. Each stent, removed at 2, 4, 6 and 8 weeks, was compared with a control stent not exposed to bile juice. RESULTS: Gross examination showed that stents were intact at 2 weeks, but at 4, 6 and 8 weeks cracks were observed. The size of these increased gradually in accordance with the duration of exposure, and at 8 weeks several large holes in the polyurethane membrane were evident. With regard to radial tensile strength, extension and peak load at break were 84.47% and 10.030 N/mm, 54.90% and 6.769 N/mm, 16.55% and 2.452 N/mm, 11.21% and 1.373 N/mm at 0, 2, 4 and 6 weeks, respectively. Scanning electron microscopy at 2 weeks revealed intermittent pitting and cracking, and examination at 4, 6 and 8 weeks showed that the size of these defects was gradually increasing. CONCLUSION: When the polyurethane membrane was exposed to bile, biodegradation was first observed at week two and increased gradually according to the duration of exposure.

Nostril stenosis is a rare disease causing cosmetic problem and nasal airway obstruction. Various etiologies including iatrogenic cause the stenosis. Usually the shortage of internal lining of vestibule initiates secondary intention healing where granulation and contracture results in the stenosis. Many surgical techniques have been used to correct the stenosis. The objective of this article is to present a case of iatrogenic unilateral nostril stenosis which was successfully repaired with the use of auricular composite graft.

PURPOSE: In recent years, single-port laparoscopic appendectomy (SPLA) has been gaining in popularity and there have been many reports on the results of SPLA. The purpose of this study is to investigate feasibility, safety, and cosmetic satisfaction with SPLA in treatment of perforated appendicitis. METHODS: From September 2012 to March 2015, 227 patients underwent SPLA at Damsoyu hospital. The patients were divided into the simple and gangrenous appendicitis group (the S & G group) and the perforated appendicitis group (the P group). Operation time, hospital stay, drain insertion rate, surgical complication, and cosmetic satisfaction were evaluated. RESULTS: A total of 227 patients consisted of 32 patients in the P group and 195 patients in the S & G group. There were no significant differences in the demographic data of the patients. The operation time and hospital stay were significantly longer in the P group (p=0.002 and p<0.0001, respectively). The rate of drain insertion was also higher in the P group (p=0.0002). However, no differences in postoperative complications (p=0.281) and cosmetic satisfaction (p=0.090) were observed between the two groups. CONCLUSION: SPLA for perforated appendicitis is a feasible, safe, and cosmetically acceptable procedure. However, longer operation time and hospital stay and higher drain insertion rate should be considered for patients undergoing SPLA for perforated appendicitis.

Primary ovarian pregnancy is comparatively rare in ectopic pregnancy. Ovarian pregnancy occurs in corpus luteum cyst and is usually accompanied with the rupture of ovary and a massive hemoperitoneum. It presents as a hemorrhagic ovary and frequently misdiagnosed as a ruptured corpus luteum. Spiegelberg's criteria should be fulfilled for the diagnosis of ovarian pregnancy. Two cases of ovarian pregnancy were presented with a brief review of the literatures.

The research of p53 is being conducted to find the mechanisms of tumorigenesis and to treat various cancers. Homeodomain-interacting protein kinase2 (HIPK2) is an important factor to regulate p53 and to increase the stability of p53. Activation of HIPK2 leads to the selective phosphorylation of p53, resulting in growth arrest and the enhancement of apoptosis. In this study, the canine HIPK2 cDNA fragments were obtained, and their overlapping regions were aligned to give a total sequence of 3489 bp. The canine HIPK2 cDNA (GenBank accession number; AY800385) shares 93% and 90% sequence identity with those of human and mouse HIPK2, respectively. The canine HIPK2 cDNA contains an open reading frame encoding 1163 amino acid residues and the predicted amino acid sequence has 98% and 96% identity with those of human and mouse, respectively. The deduced amino acid sequence of canine HIPK2 has also all domains' sites compared with human and mouse HIPK2. Therefore, these structural similarities suggested that the canine HIPK2 shares the basic biological functions that HIPK2 exhibit in other species.

OBJECTIVE: To compare the abortion time, success rate and efficiency of application of intravaginal misoprostol versus intracervical laminaria insertion and intravenous sulprostone administration for mid-trimester pregnancy termination. MATERIAL: Patients requesting termination of second trimester pregnancy were randomized into two groups. In Group I, the women were given 200 microg tablet of misoprostol placed in the posterior vaginal fornix. In Group II, the women were given laminaria insertion in cervical canal with intravenous sulprostone administration. Altogether 50 subjects were recruited with 25 women in each group. RESULTS: The mean interval from start of induction to vaginal delivery was 1480.84+/-37.73 minutes in Group I and 1236.16+/-77.59 minutes in Group II(p=0.232). The success rate of termination within 48 hours in Group I and Group II were 84%, 92%(p=0.384). There were no significant differences in the mean interval time and success rates. Measurement of blood loss(differs in hemoglobin between the admission and postabortive 24 hours) shows in Group I(1.0352+/-0.5774) and in Group II(1.5640+/-0.8976). Mean changes in hemoglobin level were significantly lesser in the misoprostol group(p=0.017). No serious complication occurred. CONCLUSION: Intravaginal misoprostol appears to be acceptably safe and effective agents for second trimester pregnancy termination.
