OBJECTIVE: Holmium laser enucleation of prostate (HoLEP) is as fast-paced treatment that is one of the standard treatment for benign prostate hypoplasia. However, there is a rare case that the satisfaction rate of surgery is lowered due to storage symptoms such as frequency and urgency. We investigated the risk factors of bladder irritation symptoms persisted after holmium laser enucleation of prostate. METHODS: From January 2009 to December 2014, 220 patients underwent HoLEP in Soonchunhyang University Cheonan Hospital. Among them, 133 patients were selected who did not have any problem that could affect the voiding function including urologic cancer, neurogenic bladder, urinary tract infection, and bladder stone disease. At 3 months after surgery patients were divided into two groups: postoperative International Prostate Symptom Score (IPSS) storage symptom scores <8 (group I) and ≥8 (group II). The two groups were analyzed the parameters: preoperative (prostate size, uroflowmetry, IPSS, prostate calcification), intraoperative (operative time, resected prostate weight), and postoperative (IPSS, uroflowmetry). RESULTS: Of the 133 patients, 94 patients were assigned to group I and 39 patients were group II. Age of the patients, the prostate size, and maximal urinary flow rate showed no statistical difference in both groups. Preoperative storage symptom scores were significantly higher in group II (P<0.05) and IPSS voiding-to-storage subscore ratio was lower in group II without significance (P<0.05). The prostate calcification, periurethral prostatic calcification, and intravesical prostatic protrusion was no difference in the two groups. Postoperative IPSS, maximal urinary flow rate, and post-void residual urine volume was improved in two groups but storage symptom score was not improved in group II. Operative time and resected prostate weight were not found the differences, and postoperative parameters (maximal urinary flow rate, post-void residual urine volume) were showed no difference in both groups. However all of the IPSS was higher in group II. CONCLUSION: Many symptom improvements after HoLEP were observed but some patients may have difficulties due to persistent bladder irritation. Because bladder irritation sign could persist after surgery if preoperative storage symptom score was higher, it is necessary for a detailed description before surgery.

BACKGROUND: The aim of this study was to evaluate the feasibility of single-port video-assisted thoracic surgery (VATS) in the treatment of secondary spontaneous pneumothorax (SSP). METHODS: Twenty-four patients who were scheduled to undergo single-port VATS for SSP were studied. The medical records of the patients were retrospectively reviewed. The mean follow-up duration was 26.1+/-19.8 months. In order to evaluate the feasibility of single-port VATS for SSP, the postoperative results of single-port VATS (n=15) in patients with emphysema were compared with those of emphysematous patients who underwent three-port VATS (n=15) during the study period. RESULTS: Single-port VATS was feasible in 19 of 24 patients (79.2%), while an additional port was needed in five patients. In the single-port VATS patients, the median operation time, duration of chest tube drainage, and hospital stay were 84.0 minutes, one day, and two days, respectively. Postoperative complications included prolonged chest tube drainage for more than five days (n=1), wound infection (n=1), and vocal fold palsy (n=1). No recurrence of pneumothorax was observed during the follow-up period. The median operation time, duration of chest tube drainage, and hospital stay of the emphysematous patients who underwent single-port VATS were shorter than those who underwent three-port VATS group (p<0.05 for all parameters). CONCLUSION: Single-port VATS proved to be a feasible procedure in the treatment of patients with secondary spontaneous pneumothorax.

PURPOSE: To analyze blinking patterns when watching an ultra-high definition (UHD) television and to compare the results between normal eyes and dry eyes. METHODS: A total of 59 participants aged from 13 to 69 years were instructed to watch a colorful and dynamic video on a UHD television for 10 minutes. Before and after watching the UHD television, we measured the best corrected visual acuities, autorefraction, tear-break-up-time, degree of corneal erosion and conjunctival hyperemia via slit lamp biomicroscopy. In addition, questionnaires for the evaluation of eye fatigue and symptoms of a dry eye were completed. The definition of dry eye syndrome was that the tear-break-up-time of one of the eyes was less than 5 seconds, conjunctival injection, or marked corneal erosion. The number of blinks and the duration of blinking were both measured and analyzed at the early and late phases of video-watching. RESULTS: After watching the UHD television in the normal eye group, the tear-break-up-time was significantly decreased (p < 0.001) and the degree of corneal erosion was significantly increased (p = 0.023). However, the subjective symptoms of participants were not aggravated (p = 0.080). There were no significant differences in blinking patterns in the dry eye group. On the other hand, in the normal eye group, the mean blinking time was significantly increased (p = 0.030). CONCLUSIONS: Watching an UHD television changes the tear-break-up-time, degree of corneal erosion, and blinking pattern in normal eyes, which may increase the risk of dry eye syndrome.

White fibrous papulosis of the neck is a rare skin disease that manifests with tiny papules that are distributed on the neck. Thick collagen bundles in the papillary dermis and diminution of the elastic fiber are characteristic on histologic examination. It is thought to be a normal aging process of the skin or an associated disorder. We report here on a case of white fibrous papulosis of the neck of a 49-year-old Korean woman.

Phage display technology provides a powerful tool to screen a library for a binding molecule via an enrichment process. It has been adopted as a critical technology in the development of therapeutic antibodies. However, a major drawback of phage display technology is that because the degree of the enrichment cannot be controlled during the bio-panning process, it frequently results in a limited number of clones. In this study, we applied next-generation sequencing (NGS) to screen clones from a library and determine whether a greater number of clones can be identified using NGS than using conventional methods. Three chicken immune single-chain variable fragment (scFv) libraries were subjected to bio-panning on prostate-specific antigen (PSA). Phagemid DNA prepared from the original libraries as well as from the Escherichia coli pool after each round of bio-panning was analyzed using NGS, and the heavy chain complementarity-determining region 3 (HCDR3) sequences of the scFv clones were determined. Subsequently, through two-step linker PCR and cloning, the entire scFv gene was retrieved and analyzed for its reactivity to PSA in a phage enzyme immunoassay. After four rounds of bio-panning, the conventional colony screening method was performed for comparison. The scFv clones retrieved from NGS analysis included all clones identified by the conventional colony screening method as well as many additional clones. The enrichment of the HCDR3 sequence throughout the bio-panning process was a positive predictive factor for the selection of PSA-reactive scFv clones.

PURPOSE: The aim of this study was to investigate the clinical characteristics and causative organisms of meningitis in the Daegu region and seek a useful tool for the early prediction of bacterial meningitis in children. METHODS: We retrospectively reviewed the medical records of 115 pediatric patients diagnosed with bacterial or aseptic meningitis at Yeungnam university hospital in Daegu from March 2012 to July 2013. We evaluated their clinical symptoms, laboratory findings, clinical courses, bacterial meningitis scores and complications. RESULTS: The subjects included 106 with aseptic meningitis and 9 with bacterial meningitis. At the time of visit, fever was the most frequent symptom, followed by headache, vomiting and neck stiffness. In cerebrospinal fluid (CSF) analysis, white blood cell (WBC) count were higher in the bacterial meningitis group (1423.8+/-1980.4 vs. 120.0+/-161.6 mg/dL). Mean CSF protein was 219.4+/-183.6 mg/dL in bacterial meningitis and 42.4+/-27.0 mg/dL in aseptic meningitis (P <0.001). Bacterial meningitis score (BMS) were higher in the group with bacterial meningitis. Abnormal radiological findings were found in 44% of the group with bacterial meningitis. CONCLUSION: Although the clinical features between the groups were similar, the CSF analysis revealed significant differences statistically. Furthermore, BMS could be helpful to predict bacterial meningitis in children. During the outbreak of aseptic meningitis, it might reduce unnecessary hospital admissions and antibiotic treatments.

PURPOSE: We conducted a retrospective analysis to determine if adjuvant chemotherapy prolongs overall survival in patients with pathologic stage IB lung adenocarcinoma who had undergone complete resection and were defined as high-risk by a newly developed recurrence risk scoring model. MATERIALS AND METHODS: Patients who underwent curative resection for stage IB lung adenocarcinoma were analyzed with a newly developed recurrence risk scoring model and divided into a low-risk group and a high-risk group. The patients in the high-risk group were retrospectively divided into two groups based on whether they underwent adjuvant chemotherapy or observation. Recurrence-free survival and overall survival were compared between these two groups. RESULTS: A total of 328 patients who underwent curative resection between 2000 and 2009 were included in this study, of whom 110 (34%) received adjuvant chemotherapy and 218 (67%) underwent observation without additional treatment. According to our risk model, 167 patients (51%) were high-risk and 161 (49%) were low-risk. The 5-year recurrence-free survival rates and overall survival were 84.4% and 91.5% in low-risk patients and 53.9% and 74.7% in high-risk patients (p < 0.001). In high-risk patients, the 5-year overall survival rates were 77% among patients who underwent observation and 87% among those who underwent adjuvant chemotherapy (p=0.019). CONCLUSION: Adjuvant chemotherapy prolonged overall survival among high-risk patients who had undergone complete resection for stage IB lung adenocarcinoma.
