Background:
Spine-hip discordance (SHD) increases fracture risk. However, its prevalence and clinical implications have not been investigated in patients with hip fractures. This study determined the prevalence and association of SHD with mortality and investigated the cause of SHD in patients with hip fractures.
Methods:
This study included patients admitted for fragility hip fractures between 2011 and 2020. All patients underwent dual energy X-ray absorptiometry and anteroposterior and lateral views of the lumbosacral spine during admission. Data on demographics, diagnosis, American Society of Anesthesiologists score, and mortality were collected. A T-score difference of more than 1.5 between L1-4 and the femur neck was considered discordant, and 3 groups (lumbar low [LL] discordance, no discordance [ND], and femur neck low [FL] discordance) were compared. In the discordance group, lumbar radiographs were reviewed to determine the cause of discordance.
Results:
Among 1,220 eligible patients, 130 were excluded due to patient refusal or bilateral hip implantation; therefore, this study included 1,090 patients (271 male and 819 female). The prevalence of LL, ND, and FL was 4.4%, 66.4% and 29.2% in men and 3.9%, 76.1%, and 20.0% women. Mortality was not associated with discordance. The most common causes of discordance were physiological in the LL group and pathological in the FL group for both sexes.
Conclusions
Patients with hip fractures showed lower rates of ND and higher rates of FL compared to the general population. True discordance should be carefully judged for pathological and artifact reasons. The clinical implications of SHD require further investigation.

PURPOSE:
. The aim of this study was to examine the importance of the defect-free scanning of a scan body by assessing the accuracy of virtual implant positioning in computer-aided design (CAD) software when the scan body image is improperly scanned.
MATERIALS AND METHODS:
. A scan body was digitized in a dentiform model using an intraoral scanner, and scanned images with differing levels of image deficiency were generated: 5%, 10%, and 15% deficiency in the flat or rounded area. Using a best-fit image matching algorithm on each of the deficient scan body images, corresponding virtual implants were created. The accuracy of the implant position was evaluated by comparing the linear and angular discrepancies between the actual and virtual positions of the implant. Kruskal-Wallis tests and Mann-Whitney U tests with Bonferroni correction were used to determine the statistical differences among the seven scanned image deficiency groups (α=.05).
RESULTS:
. In general, the linear and angular discrepancies of the implant position in the software increased as the deficiency of the scan body images increased. A 15% scan body image deficiency generated larger discrepancies than deficiency of 5% and 10%. The difference of scan defect position, flat or rounded area, did not affect the accuracy of virtual implant orientation at 5% and 10% deficiency level, but did affect the accuracy at 15% deficiency level.
CONCLUSION
. Deficiencies in the scanned images of a scan body can decrease the accuracy of the implant positioning in CAD software when the defect is large, thus leading to the incorrect fabrication of implant prostheses.

PURPOSE: Differences in the severity of subjective symptoms have been noted depending on whether a Hunner lesion is present in women with interstitial cystitis/bladder pain syndrome (IC/BPS). In this study, we aimed to identify differences in objective urodynamic parameters in women with IC/BPS according to the presence of a Hunner lesion. METHODS: This cross-sectional study included a total of 55 patients with IC/BPS. IC/BPS and the presence of a Hunner lesion on cystoscopy were diagnosed according to American Urological Association guidelines. The patients were categorized into a Hunner IC/BPS group and a non-Hunner IC/BPS group according to the presence of a Hunner lesion on cystoscopy. At the initial visit, a medical history was taken from all patients with IC/BPS, and they underwent symptom assessment using a 3-day voiding diary and laboratory tests. A urodynamic study was then performed before any treatment was performed. Baseline characteristics and urodynamic parameters were compared between the 2 groups. RESULTS: Of the 55 patients, 23 (41.8%) had a Hunner lesion on cystoscopy. As documented in the voiding diaries, the Hunner IC/BPS group had more frequent voids and a smaller maximal voided volume (P=0.045, P < 0.001, respectively). Regarding urodynamic parameters, the mean volume at the first desire to void, normal desire to void, strong desire to void (SDV), and maximum cystometric bladder capacity (MBC) was significantly lower in the Hunner IC/BPS group (P=0.001, P=0.004, P < 0.001, and P < 0.001, respectively). On receiver operating characteristic curve analysis, patients with an SDV≤210 mL (area under the curve [AUC]=0.838, P < 0.001) and an MBC≤234 mL (AUC=0.857, P < 0.001) were likely to be in the Hunner IC/BPS group. CONCLUSIONS: The differences in patients’ subjective symptoms between the Hunner IC/BPS and non-Hunner IC/BPS groups were confirmed to correspond to differences in objective urodynamic parameters.

PURPOSE: This study was designed to evaluate the efficacy of medical treatment of Peyronie's disease. MATERIALS AND METHODS: A total of 109 patients with Peyronie's disease who had been treated from January 2011 to December 2014 were retrospectively reviewed in this study. Forty-four patients (Group 1) were treated with 12 mg of potassium para-aminobenzoate daily. Sixty-five patients (Group 2) were treated with combination therapy: tamoxifen (20 mg) and acetyl-L-carnitine (300 mg) twice daily in addition to a phosphodiesterase type 5 inhibitor. Ability to perform sexual intercourse, pain during erection, size of plaque, and penile curvature angle were assessed. RESULTS: In Group 1, 30 of 44 patients (68.2%) discontinued treatment within 12 weeks, while 5 patients (7.7%) in Group 2 discontinued treatment. Pain during erection and plaque size were improved in both groups but showed no statistical difference due to the high dropout rate in Group 1. In both groups, penile curvature was improved, but demonstrated no statistical difference between the treatment groups. However, combination therapy demonstrated a better response rate in patients whose penile curvature angle was less than 30° (44.4% vs. 79.1%, p=0.048). The rate of successful sexual intercourse was significantly higher in Group 2 (42.8% vs. 78.3%, p=0.034). The number of patients who underwent surgical correction despite medical treatment was significantly higher in Group 1 (35.7% vs. 13.3%, p=0.048). CONCLUSIONS: Early medical combination therapy in Peyronie's disease may present better results in patients whose curvature angle is less than 30°.

Hemobilia is a rare gastrointestinal bleeding, usually caused by injury to the bile duct. Hemobilia after endoscopic retrograde cholangiopancreatography (ERCP) is generally self-limiting and patients will spontaneously recover, but some severe and fatal hemorrhages have been reported. ERCP-related bowel or bile duct perforation should be managed promptly, according to the type of injury and the status of the patient. We recently experienced a case of late-onset severe hemobilia in which the patient recovered after endoscopic biliary stent insertion. The problem was attributable to ERCP-related bile duct perforation during stone removal, approximately 5 weeks prior to the hemorrhagic episode. The removal of the stent was performed 10 days before the onset of hemobilia. The bleeding was successfully treated by two sessions of transarterial coil embolization.

Biting midges belonging to the genus Culicoides (Diptera: Ceratopogonidae) were collected by Mosquito Magnet(R) and black light traps at 5 sites on Jeju-do, Republic of Korea (Korea), from May-November 2013 to determine species diversity and seasonal distribution. A total of 4,267 specimens were collected, of which 99.9% were female. The most common species was Culicoides tainanus (91.8%), followed by C. lungchiensis (7.2%) and C. punctatus (0.6%), while the remaining 4 species accounted for <0.5% of all Culicoides spp. that were collected. High numbers of C. tainanus were collected in May, followed by decreasing numbers through August, and then increasing numbers through November when surveillance was terminated. Peak numbers of C. lungchiensis were collected during September, with low numbers collected from May-August and October-November. The presence of C. lungchiensis in Korea was confirmed by morphological and molecular analyses.

OBJECTIVE: To evaluate the validity of quantitative lymphoscintigraphy as a useful lymphedema assessment tool for patients with breast cancer surgery including axillary lymph node dissection (ALND). METHODS: We recruited 72 patients with lymphedema after breast cancer surgery that included ALND. Circumferences in their upper limbs were measured in five areas: 15 cm proximal to the lateral epicondyle (LE), the elbow, 10 cm distal to the LE, the wrist, and the metacarpophalangeal joint. Then, maximal circumference difference (MCD) was calculated by subtracting the unaffected side from the affected side. Quantitative asymmetry indices (QAI) were defined as the radiopharmaceutical uptake ratios of the affected side to the unaffected side. Patients were divided into 3 groups by qualitative lymphoscintigraphic patterns: normal, decreased function, and obstruction. RESULTS: The MCD was highest in the qualitative obstruction (2.76+/-2.48) pattern with significant differences from the normal (0.69+/-0.78) and decreased function (1.65+/-1.17) patterns. The QAIs of the axillary LNs showed significant differences among the normal (0.82+/-0.29), decreased function (0.42+/-0.41), and obstruction (0.18+/-0.16) patterns. As the QAI of the axillary LN increased, the MCD decreased. The QAIs of the upper limbs were significantly higher in the obstruction (3.12+/-3.07) pattern compared with the normal (1.15+/-0.10) and decreased function (0.79+/-0.30) patterns. CONCLUSION: Quantitative lymphoscintigraphic analysis is well correlated with both commonly used qualitative lymphoscintigraphic analysis and circumference differences in the upper limbs of patients with breast cancer surgery with ALND. Quantitative lymphoscintigraphy may be a good alternative assessment tool for diagnosing lymphedema after breast cancer surgery with ALND.

Behcet's disease is a systemic inflammatory disorder of unknown etiology, characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. Renal involvement is rare in patients with Behcet's disease particularly immunoglobulin A (IgA) nephropathy. Other autoimmune diseases have been associated with increased risk of malignancy, but not Behcet's disease. Some cases of Behcet's disease accompanied by bladder cancer, thyroid cancer, stomach cancer, or hematologic malignancies have been reported. However, to the best of our knowledge, co-occurrence of Behcet's diseases with thymic carcinoma has not yet been reported. We experienced a 49-year-old male patient who had been treated for Behcet disease and IgA nephropathy, who presented with a large mediastinal mass on chest x-ray. After thymectomy, he was diagnosed with thymic carcinoma with complete resection.

In women, urethral condyloma rarely leads to a bladder outlet obstruction. A 39-year-old woman who presented with frequency, urgency, and residual urine sensation was found to have a condyloma in her urethral meatus. Urodynamic study indicated bladder outlet obstruction. After condyloma excision, she returned to normal voiding, and the free maximum flow rate improved. In women, excision of urethral condylomas that cause obstruction can be an effective treatment with early recovery of voiding function.

PURPOSE: This study was performed to investigate the discomfort reported by patients taking phosphodiesterase type 5 inhibitors (PDE5Is) in clinical practice. MATERIALS AND METHODS: From September 2011 to March 2012, we surveyed patients who were prescribed PDE5Is for erectile dysfunction (ED). The questionnaire elicited information concerning: patient characteristics, medication counseling received and inconveniences experienced in hospitals and at pharmacies, effects of PDE5Is, and the separation of the prescribing and the dispensing of PDE5Is. RESULTS: A total of 237 patients completed the questionnaire (mean age: 58.81+/-9.14 years). Among the 62 patients (26.0%) who reported having encountered some inconveniences in hospitals, the most frequently expressed concerns 'assistant staff,' including nurses (38.7%), 'testing procedures' (27.4%), and 'the issuing of prescriptions' (22.6%). Of the 137 patients (57.8%) who noted inconveniences in obtaining medications from pharmacies, 60.6% cited 'self-consciousness' as the most common reason, followed by 'insufficient medication counseling' (22.6%), and 'absence of consultation' (11.6%). In contrast, 82% of the patients were satisfied with the medication counseling that they had received in hospitals, covering drug usage, side effects, and precautions regarding PDE5Is; this proportion was only 30% for pharmacies. Further, most patients (89%) indicated that they preferred to obtain their prescriptions and medications for ED from the hospital at the same time. CONCLUSIONS: Treatment of ED is a highly private matter. According to the survey, ED patients more often felt that obtaining medication from pharmacies was inconvenient. The sociocultural aspects of ED necessitate that exceptions to separating the prescribing and the dispensing of medication be considered.
