Isolated torsion of the fallopian tube in postmenopausal women is rare. In this case report, we detail the case of a 53-year-old patient who presented with adenomyosis and a left hydrosalpinx with high levels of CA 125 and CA 19-9. The isolated torsion of the left hydrosalpinx was observed during the operation. The serum levels of CA 125 and CA 19-9 were reduced from 129.62 and 348 to 58.2 and 12.41 U/mL, respectively, after total laparoscopic hysterectomy with salpingectomy. On radiologic evaluation, there were no other factors that may have influenced the increase in serum levels of CA 125 and CA 19-9 in this patient, which were reduced after operation. To the best of our knowledge, this is the first case of association between perioperative changes in CA 19-9 levels and isolated torsion of the fallopian tube.

Fibroepithelial polyp (FEP) and lymphangioma circumscriptum (LC) of the vulva are rare diseases that occur generally in young to middle-aged women. The pathogenesis of FEP is not clearly understood. Several previous cases have suggested that a hormonal influence may be a predisposing condition for developing FEP with or without chronic inflammation. A 68-year-old postmenopausal woman presented with a history of multiple raised lesions on the vulva with a 1-year duration. Additionally, a pedunculated mass had appeared 6 months earlier in the left lower labia minora. The patient underwent simple excision by electrocautery. The final pathological diagnosis was FEP with LC. In this case, the development of FEP was associated only with chronic inflammation induced by LC. Therefore, the case supports the hypothesis that a chronic inflammatory process may be related to the development of FEP even without hormonal influence.

PURPOSE: The purpose of this study was to investigate the effects of the surface morphology of the implant neck on marginal bone stress measured by using finite element analysis in six implant models. MATERIALS AND METHODS: The submerged type rescue implant system (Dentis co., Daegu, Korea) was selected as an experimental model. The implants were divided into six groups whose implant necks were differently designed in terms of height (h, 0.4 and 1.0 mm) and width (platform width, w = 3.34 + 2b [b, 0.2, 0.3 and 0.4 mm]). Finite element models of implant/bone complex were created using an axisymmetric scheme. A load of 100 N was applied to the central node on the top of crown in parallel with the implant axis. The maximum compression stress was calculated and compared. RESULTS: Stress concentration commonly observed around dental implants did not occur in the marginal bone around all six test implant models. Marginal bone stress varied according to the implant neck bevel which had different width and height. The stress was affected more markedly by the difference in height than in width. CONCLUSION: This result indicates that the implant neck bevel may play an important role in improving stress distribution in the marginal bone area.

Today, adipose tissue derived mesenchymal stem cells (ADSC) have gained a great interest in various medical fields due to the characteristics of its self-renewal and multilineage differentiation capacity. The stromal vascular fraction (SVF) of adipose tissue is known to contain mesenchymal stem cells and it is obtained by processing the lipoaspirate which is usually collected from tumescent liposuction. In this study, we reviewed the records of patient epidemiology and results of SVF isolation. 30 patients (8 males and 22 females) had been underwent tumescent liposuction between April 2012 and January 2013, and the collected lipoaspirates were processed to isolate SVF in GMP facility in CHA Bundang Medical Center. The average stem cell count per 1 cc of lipoaspirate was 52,252 +/- 26,704 and cell count including red blood cells per 1cc of lipoaspirate was 970,607 +/- 873,436. The stem cell viability was proven to be 84 +/- 4%. Bacteria were not detected in all the SVF samples. Compared to previous reports concerning the yield of SVF, our results coincide well with the results of previous studies. Because there were no domestic report about the yield and viability of SVF, this report may provide a reference value of the Korean SVF for the clinicians who want to use SVF as a therapeutic purpose.

Immediate breast reconstruction in breast cancer patients is universalized and now with a wide variety of methods to choose from, we can select a breast reconstruction method according to the patient's condition. Among these methods, immediate breast reconstruction with TRAM free flap is the most commonly used. Nipple reconstruction is usually performed as a secondary procedure, reconstructed. Nipple is reconstructed with contralateral nipple composite graft or with local flap. Areola is reconstructed with skin graft and tattooing. Therefore, to reconstruct complete breast, two or more staged operations are needed and are troublesome to both the surgeon and the patient. If we could reconstruct breast mound and nipple at same time, we would reduce the operative stages and heighten the patient's satisfaction. The author performed delayed or immediate breast reconstruction with TRAM free flap and nipple reconstruction at the same time. If the TRAM flap was to situate in the whole of the breast or at the center of the breast mound, nipple was reconstructed with a local flap from the TRAM flap. If the TRAM flap was not situated in center of breast mound, nipple was reconstructed with a local flap from remnant breast skin. Immediate nipple reconstructions in breast reconstruction consisted total of 22 cases. Among these, delayed breast reconstruction were 5 cases and immediate breast reconstruction were 17 cases. According to patient's condition and mastectomy method, nipple reconstruction method was selected; nipple reconstruction with contralateral nipple composite graft(3 cases); nipple reconstruction with remnant breast skin(6 cases); nipple reconstruction from flap margin(10 cases); nipple reconstruction with prefabricated nipple on flap(3 cases). Malposition of the reconstructed nipple was the most common and serious complication(6 cases). The other complications were atrophy of the nipple(1 case), and necrosis(1 case). Reconstruction of the breast and nipple at the same time can reduce the need of a secondary operation and use remnant skin or redundant flap tissue maximally. On the other hand, it must be considered that position and shape of nipple could be deformed, because the nipple reconstruction is performed before the shape of reconstructed breast settles completely. Prudent attention is needed, because the danger of complication is higher than delayed nipple reconstruction.

OBJECTIVE: Vertebral distraction is routinely performed during anterior cervical discectomy and fusion (ACDF). Overdistraction can injure the facet joints and may cause postoperative neck pain consequently. The purpose of this study was to investigate the clinical relevance of distraction force during ACDF. METHODS: This study included 24 consecutive patients with single level cervical disc disease undergoing single level ACDF. We measure the maximum torque just before the the arm of the Caspar retractor was suspended by the rachet mechanism by turning the lever on the movable arm using a torque meter. In order to turn the lever using the torque driver, we made a linear groove on the top of the lever. We compared the neck disability index (NDI) and visual analogue scale (VAS) scores between the high torque group (distraction force>6 kgf.cm) and the low torque group (distraction force< or =6 kgf.cm) at routine postoperative intervals of 1, 3, 5 days and 1, 3, 6 months. RESULTS: The VAS scores for posterior neck pain had a linear correlation with torque at postoperative 1st and 3rd days (y=0.99x-1.1, r2=0.82; y=0.77x-0.63, r2=0.73, respectively). VAS scores for posterior neck pain were lower in the low torque group than in the high torque group on both 1 and 3 days postoperatively (3.1+/-1.3, 2.6+/-1.0 compared with 6.0+/-0.6, 4.9+/-0.8, p<0.01). However, the difference in NDI scores was not statistically significant in all postoperative periods. CONCLUSION: Vertebral distraction may cause posterior neck pain in the immediate postoperative days. We recommend not to distract the intervertebral disc space excessively with a force of more than 6.0 kgf.cm.

It is known that E-cadherin, playing a role in the differentiation of the various tissues, is expressed in the early stage of development. In this research, the expression of E-cadherin and the presence of the intracellular E-cadherin mRNA in the developing fetal rat palatine epithelium using immunohistochemistry and in situ RT-PCR are studied. The investigator also performs TUNEL method and TEM technique for detecting the apoptosis in the palatine epithelium. Fetal rats on the 14th, 15th, 16th and 18th day of gestation were used. The results obtained were as follows: Before the fusion of the both palatine shelves, E-cadherin was expressed in the oral part epithelium. After the fusion oral epithelium and original triangular area were reacted strongly. TUNEL positive cells were rarely found on the midline palatine epithelium in fused palatine processes. On the 18th day of gestation, the remodeling time, many apoptotic cells were observed in the original triangular area. It is suggested that E-cadherin plays a role in the fusion of the palatine shelves, especially in the fusion between the oral part and lower part of midline epithelium, and apoptosis plays a major role in the remodeling of the palate.

BACKGROUND: This study was purposed to identify the knowledge and performance level of the infection control guidelines and to improve their performance level of infection control for those nurses who care patients directly. METHODS: This study was based on the survey questionnaires about infection control guidelines with the total 626 nurses in Seoul and Kyunggi areas for the period between May 26, 2003 and July 14, 2003. RESULTS: The average knowledge level of infection control was 0.84 +/-0.07 (score range 0-1) and the average performance level of the infection control was 4.44+/-10.27 (score range 0-5). The correlation between knowledge and performance of the infection control showed positive correlation (r=.39; P<.001). The knowledge and performance level of the 'Prevention of the central catheter infection' were higher than other infection control guidelines. The performance levels of the 'Prevention of the surgical site infection' were lower than other infection control guidelines. The correlation between knowledge and performance of the 'Prevention of the nosocomial pneumonia' (r=.389; P<.001). 'Prevention of the urinary tract infection' (r=.325; P<.001), 'Prevention of the central catheter infection (r=.290; P<.001) and 'Intravascular infection control' (r=.446; P<.001) showed positive correlation. CONCLUSION: The study demonstrated that the nurses' knowledge and performance of infection control guidelines showed positive correlation. So the education on the infection control is required indispensably and it would contribute to reduce the hospital infection rate by performing the right treatment on the infection control with the basis of accurate knowledge.
