Delayed breast reconstruction is challenging because it requires a large volume and symmetry, and the dual-pedicled deep inferior epigastric perforator (DIEP) flap is used with microvascular augmentation. However, candidate recipient vessels in patients who have undergone radiation therapy may be damaged, with uncertain patency. This report suggests a novel method, the dual-pedicled conjoined abdominal flap, in which a free DIEP flap is combined with a pedicled transverse rectus abdominis muscle (TRAM) flap. A 57-year-old female patient who had undergone modified radical mastectomy and radiotherapy 25 years previously was referred for breast reconstruction. A whole abdominal flap was needed, but supercharged anastomosis was very risky due to calcification and scarring of the internal mammary vessel. Therefore, the thoracodorsal vessels were anastomosed with a free left DIEP flap, which was combined with a right-pedicled TRAM flap. The reconstructed volume was sufficient, and the blood flow was intact. The patient presented a symmetric contour without any complications after 4 months. The dual-pedicled conjoined abdominal flap is reliable for delayed breast reconstruction that requires a large volume and skin replacement, especially in patients with radiation-injured recipient vessels. Even if microscopic anastomosis failure occurs, secondary rescue is made possible by the pedicled TRAM flap.

Gastrointestinal tract involvement in undifferentiated pleomorphic sarcoma (UPS) is extremely rare. To the authors' knowledge, only 21 cases of primary small bowel UPS have been reported in the literature available in English. Reported CT findings in primary small bowel UPS have been nonspecific, and MRI findings have been reported in only one case. The present article describes a case involving a 72-year-old male with histologically confirmed primary UPS arising from the ileum, focusing on both CT and magnetic resonance enterography findings. On CT, primary small bowel UPS was noted as a heterogeneously enhanced small bowel mass without obstruction. Magnetic resonance enterography revealed heterogeneous intermediate T1 and T2 signal intensity, with hemorrhagic or necrotic foci within the mass and heterogeneous enhancement. The differential diagnosis included malignant gastrointestinal tumor; however, the prognosis of UPS is worse, with higher incidences of extra-abdominal metastasis.

BACKGROUND/OBJECTIVES: We compared changes in heart-femoral pulse wave velocity (hfPWV) in response to low sodium and high sodium diet between individuals with sodium sensitivity (SS) and resistance (SR) to evaluate the influence of sodium intake on arterial stiffness. SUBJECTS/METHODS: Thirty-one hypertensive and 70 normotensive individuals were given 7 days of low sodium dietary approach to stop hypertension (DASH) diet (LSD, 100 mmol NaCl/day) followed by 7 days of high sodium DASH diet (HSD, 300 mmol NaCl/day) during 2 weeks of hospitalization. The hfPWV was measured and compared after the LSD and HSD. RESULTS: The hfPWV was significantly elevated from LSD to HSD in individuals with SS (P = 0.001) independently of changes in mean arterial pressure (P = 0.037). Conversely, there was no significant elevation of hfPWV from LSD to HSD in individuals with SR. The percent change in hfPWV from the LSD to the HSD in individuals with SS was higher than that in individuals with SR. Subgroup analysis revealed that individuals with both SS and hypertension showed significant elevation of hfPWV from LSD to HSD upon adjusted analysis using changes of the means arterial pressure (P = 0.040). However, there was no significant elevation of hfPWV in individuals with SS and normotension. CONCLUSION: High sodium intake elevated hfPWV in hypertensive individuals with SS, suggesting that high sodium intake increases aortic stiffness, and may contribute to enhanced cardiovascular risk in hypertensive individuals with SS.

We investigated the combined moisturizing effect of liposomal serine and a cosmeceutical base selected in this study. Serine is a major amino acid consisting of natural moisturizing factors and keratin, and the hydroxyl group of serine can actively interact with water molecules. Therefore, we hypothesized that serine efficiently delivered to the stratum corneum (SC) of the skin would enhance the moisturizing capability of the skin. We prepared four different cosmeceutical bases (hydrogel, oil-in-water (O/W) essence, O/W cream, and water-in-oil (W/O) cream); their moisturizing abilities were then assessed using a Corneometer(R). The hydrogel was selected as the optimum base for skin moisturization based on the area under the moisture content change-time curves (AUMCC) values used as a parameter for the water hold capacity of the skin. Liposomal serine prepared by a reverse-phase evaporation method was then incorporated in the hydrogel. The liposomal serine-incorporated hydrogel (serine level=1%) showed an approximately 1.62~1.77 times greater moisturizing effect on the skin than those of hydrogel, hydrogel with serine (1%), and hydrogel with blank liposome. However, the AUMCC values were not dependent on the level of serine in liposomal serine-loaded hydrogels. Together, the delivery of serine to the SC of the skin is a promising strategy for moisturizing the skin. This study is expected to be an important step in developing highly effective moisturizing cosmeceutical products.

This multicenter study was undertaken to determine the efficacy of antibiotic prophylaxis and identify the risk factors for infectious complications after prostate surgery in Korean patients. A total of 424 patients who underwent surgery of the prostate were reviewed. All patients underwent urinalysis and urine culture preoperatively and postoperatively. Efficacy of antibiotic prophylaxis and risk factors for infectious complications were investigated. Infectious complications were observed in 34.9% of all patients. Factors independently associated with infectious complications were diabetes mellitus (adjusted OR, 1.99; 95% CI, 1.09-3.65, P=0.025) and operation time (adjusted OR, 1.08; 95% CI, 1.03-1.13, P=0.004). Clinicians should be aware of the high risk of infectious complications in patients with diabetes and those who undergo a prolonged operation time. Neither the type nor duration of prophylactic antibiotics resulted in differences in infectious complications.

An extratesticular scrotal epidermal cyst is a very rare condition and few cases of extratesticular scrotal epidermal cyst with radiologic findings have been reported. Therefore, we report here on a rare case with ultrasonographic and MRI findings. A 70-year-old male patient was admitted with a palpable mass in the left scrotum. A well-defined heterogeneous hypoechoic mass with scattered echogenic reflectors in the scrotum was identified on ultrasonography. The cystic mass showed high signal intensity on T2-weighted images, low signal intensity on T1-weighted images, and diffusion restriction on diffusion weighted images.

PURPOSE: The glutathione-S-transferase (GST)P1, GSTM1, and GSTT1 genotypes have been associated with an increased risk of prostate, bladder, and lung cancers. The aim of this study was to investigate the association between the GSTP1, GSTM1, and GSTT1 genotypes and the risk of prostate cancer in Korean men. MATERIALS AND METHODS: The study group consisted of 166 patients with histologically confirmed prostate cancer. The control group consisted of 327 healthy, cancer-free individuals. The diagnosis of prostate cancer was made by transrectal ultrasound-guided biopsy. Patients with prostatic adenocarcinoma were divided into organ-confined (< or =pT2) and non-organ-confined (> or =pT3) subgroups. The histological grades were subdivided according to the Gleason score. The GSTP1, GSTM1, and GSTT1 genotypes were determined by using polymerase chain reaction-based methods. The relationship among GSTP1, GSTM1, and GSTT1 polymorphisms and prostate cancer in a case-control study was investigated. RESULTS: The frequency of the GSTM1 null genotype in the prostate cancer group (54.2%) was higher than in the control group (odds ratio=1.53, 95% confidence interval=1.20-1.96). The comparison of the GSTP1, GSTM1, and GSTT1 genotypes and cancer prognostic factors, such as staging and grading, showed no statistical significance. CONCLUSIONS: An increased risk for prostate cancer may be associated with the GSTM1 null genotype in Korean men, but no association was found with the GSTT1 or GSTP1 genotypes.

BACKGROUND AND OBJECTIVES: High aerobic exercise capacity and sport-related physical activity are reported to be inversely associated with arterial stiffness in healthy young adults. However, it is unknown whether increased physical activity and/or high aerobic exercise capacity attenuate arterial stiffness in patients with untreated hypertension. SUBJECTS AND METHODS: We studied subjects with never-treated hypertension {n=84 (55 males); mean age+/-SD, 49+/-7 years; age range, 36-65 years}. We excluded subjects with a history of diabetes, angina, myocardial infarction, major arrhythmia, or cerebrovascular diseases and those who were taking any cardiovascular medications, including lipid-lowering agents. Carotid intima-media thickness (IMT) and heart-femoral pulse wave velocity (hfPWV) were measured before exercise testing was performed. Physical activity was estimated using a modified Baecke questionnaire. Aerobic exercise capacity was measured with maximal cardiopulmonary exercise testing (maximum oxygen uptake, Vo2max). RESULTS: Linear regression analysis showed a significant inverse correlation between sport-index and hfPWV (r=-0.404; p<0.001), which multiple linear regression analysis showed to be independent of the individual variables of age, gender, body mass index, mean arterial pressure, total cholesterol, fasting blood glucose, and heart rate (beta=-0.277; p=0.004). However, the work- and leisure-indices and Vo2max were not associated with hfPWV (p>0.05). Carotid IMT was not associated with physical activity indices or Vo2max. CONCLUSION: In patients with untreated hypertension, increased sport activity was associated with lower aortic stiffness, but high aerobic exercise capacity was not. These results suggest that regular daily exercise, but not exercise capacity, is an important determinant of aortic stiffness in patients with untreated hypertension.
