Urachal xanthogranuloma is an extremely rare disease. A 23-year-old man presented with severe lower abdominal pain and voiding frequency. Computed tomography revealed a urachal mass with bladder invasion, which was suspected to be a urachal carcinoma or abscess. Laparoscopic urachal resection was performed with a minimal incision. Histopathologic examination identified the mass as a urachal xanthogranuloma.

OBJECTIVE: To evaluate the effects of the videofluoroscopic swallowing study (VFSS) timing after the nasogastric tube (NGT) removal on swallowing function of the patients with dysphagia. METHODS: This study was conducted on 40 NGT-fed patients with dysphagia. To assess the patients' swallowing function, VFSS was performed twice using a 5-mL 35% diluted barium solution. For the initial examination, VFSS was performed immediately after the NGT removal (VFSS 1). For the second examination, VFSS was performed five hours after the NGT removal (VFSS 2). We used the functional dysphagia scale (FDS) to assess swallowing function. In the FDS, a significant difference in the four items in the oral phase, seven items in the pharyngeal phase, and total scores were assessed (p<0.05). We also used modified penetration-aspiration scale (mPAS) to compare the two examinations (p<0.05). RESULTS: A paired t-test was performed to confirm the statistical significance of the two examinations (p<0.05). The overall swallowing function was assessed as better in VFSS 2 than in VFSS 1. In the FDS, significant differences in the residue in valleculae (p=0.002), the residue in pyriform sinuses (p=0.001), the coating of pharyngeal wall after swallow (p=0.001), and the total scores (p<0.001) were found between the two examinations. Also, in the mPAS that assessed the degree of penetration-aspiration, a significant difference was found between the two examinations (p<0.001). CONCLUSION: The results of this study confirmed that the timing of the VFSS after the NGT removal affects the swallowing function. Thus, to accurately assess the swallowing function, VFSS must be performed in NGT-fed patients after they have rested for a certain period following the removal of their NGT.

BACKGROUND: Recently, the prevalence of obesity and socioeconomic costs stemming from obesity are increasing steeply. Obesity, in particular, has a highly polarization caused by income levels. Obesity in low-income patients is expected to become a serious social problem in the future. This study aims to observe the effects of consistent consultation and drug therapy during a six months period, and to develop the treatment process of obesity for low-income people. METHODS: The body weight, waist circumference, body mass index (BMI), and blood pressure (BP) was measured every 2 weeks, and laboratory blood tests with a survey including Beck Depression Inventory (BDI) and eating behavior index was checked at 0, 3, and 6 months. Paired t-test and linear mixed model was done to evaluate the difference between pre-treatment data and post-treatment data. RESULTS: Twenty-one patients (2 males, median age [interquartile range] of 39 years [29-46]) were analyzed. There were statistically significant reductions of body weight (P<0.01), BMI (P<0.01), waist circumference (P<0.01), low-density lipoprotein (P=0.01), BDI-I (P<0.01), eating behavior index (P<0.01). There was no statistically significant difference of safety outcome of the BP and blood tests. CONCLUSIONS: Proper obesity treatment of obese patients of low socioeconomic status was meaningful enough to affect depression and eating patterns as well as reducing body weight and decreased waist circumference.

Korean Journal of Urology 2009;50(4):375-379
PURPOSE: The methods for vasovasostomy are varied, and many authors have reported various success rates. This study aimed to assess a new method for vasovasostomy with a Prolene stent. MATERIALS AND METHODS: Among 85 patients who underwent vasovasostomy with a Prolene stent, 69 patients were retrospectively reviewed at our hospital between October 2004 and December 2007. The average age at the time of vasovasostomy was 42.2 years (range: 24.0-52.0 years). The obstructive interval was 6.25 years (range: 0.7-20.0 years). The cases were divided into 2 groups according to obstructive interval: group A (above 8 years) and group B (8 years and less), with 18 (26.1%) and 51 (73.9%) cases, respectively. Patency was defined as a sperm concentration of more than 10x106/ml on semen analysis. RESULTS: The overall patency and pregnancy rates were 76.8% and 43.4%, respectively. The patency and pregnancy rates of group A were 61.1% and 33.3%. Those of group B were 82.3% and 47.0%. The mean duration to pregnancy was 10.9 months (range: 4-31 months). The mean operation time was 90.2 minutes (range: 50.0-165.0 minutes). CONCLUSIONS: The new method of vasovasostomy with the Prolene stent has good efficacy and safety. Its benefits are the maintenance of good patency, a good pregnancy rate, and a diminished operating time.

OBJECTIVE: To determine which factors affect the rehabilitation duration in patients with congenital muscular torticollis (CMT) and to predict the duration of rehabilitation and prognosis. METHODS: One hundred and eighteen patients (79 males and 39 females) who were diagnosed with CMT and received physical therapy were enrolled in this study. We retrospectively reviewed the information in terms of sex, gestational age, birth weight, methods of delivery, fetal presentation, age at diagnosis, the affected sternocleidomastoid (SCM) muscle site, SCM muscle thickness, ratio of muscle thickness on the affected side to that on the unaffected side (called the 'abnormal/normal [A/N] ratio'), and range of motion for cervical rotation and side bending. RESULTS: The SCM muscle thickness and A/N ratio had a positive linear relationship with the rehabilitation duration. Patients who were in the breech position needed longer rehabilitation. The birth weight and age at diagnosis were negatively correlated with the rehabilitation duration. However, the cervical range of motion, mass site, sex, gestational age, and methods of delivery were not correlated with the rehabilitation duration. CONCLUSION: Patients with a thicker SCM, lower birth weight, and history of breech delivery had a longer rehabilitation duration.

BACKGROUND: The number of surgical risks recalled by a patient after surgery can be used as a parameter for assessing how well the patient has understood the informed consent process. No study has investigated the usefulness of a self-developed mobile application in the traditional informed consent process in patients with a nasal bone fracture. This study aimed to investigate whether delivery of information, such as surgical risks, through a mobile application is more effective than delivery of information through only verbal means and a paper. METHODS: This prospective, randomized study included 60 patients with a nasal bone fracture. The experimental group (n=30) received preoperative explanation with the traditional informed consent process in addition to a mobile application, while the control group (n=30) received preoperative explanation with only the traditional informed consent process. Four weeks after surgery, the number of recalled surgical risks was compared for analysis. The following six surgical risks were explained: pain, bleeding, nasal deformity, numbness, nasal obstruction, and nasal cartilage necrosis. RESULTS: The mean number of recalled surgical risks among all patients was 1.58±0.56. The most frequently recalled surgical risk was nasal deformity in both groups. The mean number of recalled surgical risks was 1.72±0.52 in the experimental group and 1.49±0.57 in the control group. There was a significant association between mobile application use and the mean number of recalled surgical risks (p=0.047). Age, sex, and the level of education were not significantly associated with the mean number of recalled surgical risks. CONCLUSION: This study found that a mobile application could contribute to the efficient delivery of information during the informed consent process. With further improvement, it could be used in other plastic surgeries and other surgeries, and such an application can potentially be used for explaining risks as well as delivering other types of information.

BACKGROUND: Trap-door deformity is a biophysical phenomenon in which U-, C-, or V-shaped linear scars tend to become depressed and the tissue circumscribed by them tends to bulge. The aim of the present study was to demonstrate the efficacy of triamcinolone acetonide (TCA) injection and subcision as a first-line treatment for post-traumatic acute trap-door deformity. METHODS: In trap-door deformity patients, a subcision was made by cutting the fibrotic band along the scar line in the depression using a 22-gauge needle. TCA was administered. An intralesional injection was made along areas of scarring that were difficult to penetrate with the needle. Scar quality parameters were assessed at each follow-up by a single observer and the patient, using the patient and observer scar assessment scale (POSAS) with an additional question about bulging. RESULTS: The average POSAS score per question on the observer scale improved from 6.6±1.31 to 3.6±1.08, and the average POSAS score per question on the patient scale improved from 5.5±1.57 to 2.5±1.26. The average bulging score on the observer scale decreased from 6.0±0.98 to 3.0±0.83, and that on the patient scale decreased from 5.0±1.67 to 2.0±1.30. The average general opinion score on the observer scale decreased from 5.5±1.12 to 3.5±0.91, and that on the patient scale decreased from 6.0±1.84 to 2.0±0.79. CONCLUSIONS: Better outcomes can be obtained by using both TCA and subcision as the first-line therapy for post-traumatic acute trap-door deformity.

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD), a prototypic halogenated aromatic hydrocarbon (HAH), is known as one of the most potent toxicants. At least a part of its toxic effects appears to be derived from its ability to induce TNF-alpha production. However, the signaling pathway of TCDD that leads to TNF-alpha expression has not been elucidated. In this study, we investigated the signaling mechanism of TCDD-induced TNF-alpha expression in PMA-differentiated THP-1 macrophages. TCDD induced both mRNA and protein expression of TNF-alpha in a dose- and time-dependent manner. Alpha-Naphthoflavone (NF), an aryl hydrocarbon receptor (AhR) inhibitor, prevented the TCDD-induced expression of TNF-alpha at both mRNA and protein levels. Genistein, a protein tyrosine kinase (PTK) inhibitor, and PD153035, an EGFR inhibitor, also blocked the increase of TNF-alpha expression by TCDD, indicating the role of EGFR in TCDD-induced TNF-alpha expression. On the other hand, PP2, a c-Src specific inhibitor, did not affect TCDD-induced TNF-alpha expression. EGFR phosphorylation was detected as early as 5 min after TCDD treatment. TCDD-induced EGFR activation was AhR-dependent since co-treatment with alpha-NF prevented it. ERK was found to be a downstream effector of EGFR activation in the signaling pathway leading to TNF-alpha production after TCDD stimulation. Activation of ERK was observed from 30 min after TCDD treatment. PD98059, an inhibitor of the MEK-ERK pathway, completely prevented the TNF-alpha mRNA and protein expression induced by TCDD, whereas inhibitors of JNK and p38 MAPK had no effect. PD153035, an EGFR inhibitor, as well as alpha-NF significantly reduced ERK phosphorylation, suggesting that ERK activation by TCDD was mediated by both EGFR and AhR. These results indicate that TNF-alpha production by TCDD in differentiated THP-1 macrophages is AhR-dependent and involves activation of EGFR and ERK, but not c-Src, JNK, nor p38 MAPK. A signaling pathway is proposed where TCDD induces sequential activation of AhR, EGFR and ERK, leading to the increased expression of TNF-alpha.

Neurofibromas of the penis, although very rare, are often associated with neurofibromatosis type 1. Primary solitary neurofibromas of the penis are extremely rare. We describe a 37-year-old man with a solitary neurofibroma in the dorsum of the penis. The patient reported difficulty with sexual intercourse owing to a penile mass and erectile dysfunction. After surgical excision of the neurofibroma, he had no pain and a normal sensation of the penile glans, and his erectile dysfunction improved. At the present time, 26 months after surgery, there has been no evidence of tumor recurrence.

PURPOSE: To compare clinical characteristics and surgical results in adolescents and adults with varicocele. MATERIALS AND METHODS: We retrospectively analyzed the characteristics of 93 patients, 34 adolescents (mean age, 14.4+/-2.1 years) and 59 adults (mean age, 30.4+/-12.4 years), who underwent surgical repair of varicocele between 2006 and 2009. Median follow-up time in all patients was 18.7 months. The most bothersome symptoms, bilaterality, grades, surgical methods, artery-sparing rates, operation times, semen analysis, success rates, and recurrence-free period were compared between the two groups. RESULTS: The overall success rate of surgical repair was 92.5%. The most bothersome symptoms were scrotal mass, pain, and hypotrophy in adolescents and pain, scrotal mass, infertility, and hypotrophy in adults (p=0.008). There were no significant between-group differences in bilaterality, grades, surgical methods, operation times, pre- or postoperative semen analyses, success rates, or recurrence-free periods. Patients who underwent artery-sparing surgery had higher recurrence rates than did those who underwent surgery that did not spare arteries. In adults, semen density increased significantly after surgery, from 35.6 million/ml to 49.6 million/ml (p=0.046). CONCLUSIONS: There were no significant differences in clinical characteristics or surgical results between adolescents and adults with varicocele, except for the most bothersome symptoms. Semen density increased after surgery in both groups.
