Purpose: To report a case of a successful secondary Descemet membrane endothelial keratoplasty in failed penetrating keratoplasty. Case summary: A 46-year-old male with keratoconus in both of his eyes underwent penetrating keratoplasty in his right eye 30 years ago and in his left eye 14 years ago. From one and a half year ago, the patient’s visual acuity decreased in his left eye due to graft failure. For treatment, secondary Descemet membrane endothelial keratoplasty was performed. Partial detachment of Descemet membrane was observed at 13 days after the operation, and an additional air injection was performed. At 8 months after the operation, the patient’s uncorrected visual acuity improved to 0.5 and the cornea maintained its clearance without rejection. Conclusions Secondary Descemet membrane endothelial keratoplasty was successfully performed in a patient with failed penetrating keratoplasty.

PURPOSE: To investigate the relationship of improvement in erectile function (EF) with improvement in lower urinary tract symptoms (LUTS) and to assess the contribution of tamsulosin dose to the improvement of EF apart from the indirect influence of LUTS improvement in men with LUTS and erectile dysfunction (ED). MATERIALS AND METHODS: Fifty patients received tamsulosin 0.2 mg/d for the first 4 weeks and were subsequently divided into two groups by patient-reported outcomes. Nonescalators were maintained starting dose and escalators increased to 0.4 mg for the remaining 8 weeks. International Prostatic Symptom Score (IPSS) and International Index of Erectile Function (IIEF-5), and underwent uroflowmetry were evaluated at baseline, and weeks 4 and 12. RESULTS: LUTS parameters were significantly improved in both groups but insignificant between the 2 groups. The degree of the improvement in the total IPSS and in the voiding, storage, and quality of life (QoL) subscores were significantly correlated with the degree of the improvement in EF; this was especially prominent in patients successfully treated LUTS. The escalators experienced a significantly greater increase in IIEF-5 scores than did the nonescalators (3.3 vs. 1.5). CONCLUSIONS: Dose escalation provided similar LUTS improvement in patients with refractory to starting dose. The improvements of LUTS were correlated with the improvement of EF. The increase in the IIEF-5 score was significantly higher in escalators. These findings imply that tamsulosin may contribute to the improvement in EF through the improvement of LUTS and QoL and direct relaxation of the corpus cavernosum in a dose-dependent fashion.

BACKGROUND: This study investigated the effectiveness of reinforced contact precautions and active surveillance cultures (ASCs) in reducing the incidence of methicillin-resistant Staphylococcus aureus (MRSA) and other healthcare-associated infections (HAIs). METHODS: A before- and after-experimental study was performed at the intensive care unit (ICU) in a university-affiliated hospital. Reinforced contact precautions were applied to all patients, and ASCs for MRSA were performed for newly admitted patients at the time of admission and once a week thereafter. The HAIs were investigated in accordance with the National Nosocomial Infections Surveillance (NNIS) definitions and compared before and after the interventions. The data were analyzed using descriptive statistics. RESULTS: The number of HAIs caused by MRSA decreased from 2.2 to 0.5 per 100 patients discharged (P=0.02) and from 3.6 to 1.0 per 1,000 patient-days (P=0.032). The number of overall HAIs decreased from 7.6 to 4.0 per 100 patients discharged (P=0.011) and from 12.7 to 7.3 per 1,000 patient-days (P=0.034). The invasive device-associated infections caused by MRSA and other pathogens decreased, but the decrease was not statistically significant. CONCLUSION: Reinforced contact precautions and ASCs were effective in decreasing both MRSA infections and overall HAIs in the ICU. Further, it was assumed that the incidence of device-associated infections would have decreased if the intervention period was extended.

PURPOSE: We wanted to evaluate the sensitivity and specificity of screening mammography and ultrasonography for breast examinations and we assessed the clinical usefulness of breast ultrasound for cancer screening. MATERIALS AND METHODS: Of all the women who visited the health promotion center of seven medical institutions from Mar 2004 to Feb 2005, we compared the sensitivity and specificity between a single use of mammography and mammography with ultrasonography for the patients who underwent both mammography and ultrasonography. Here, the reference criteria were the follow-up and the histopathology, which were performed after one year. RESULTS: A total of 1123 patients underwent both mammography and ultrasonography and they could be followed up for a year. For the 1123 patients who underwent both mammography and ultrasonography, the sensitivity and specificity of a single use of mammography were 14.3% and 86.9%, respectively. The sensitivity and specificity of mammography with ultrasonography were 85.7% and 85.9%, respectively. These results showed that the sensitivity was significantly increased when mammography was combined with ultrasonography (< 0.05). CONCLUSION: The sensitivity was improved for the cases that underwent both mammography and ultrasonography.

PURPOSE: We wanted to evaluate the value of intravenous contrast enhanced abdomen-pelvis computed tomography (CT) for diagnosing acute appendicitis and we wanted to determine which patients groups will benefit from preoperative CT. METHODS: Between January and June 2006, the medical records of 354 patients who had clinically suspected acute appendicitis were retrospectively reviewed. Appendectomy was performed in 260 patients and CT was conducted in 108 patients of the 260 patients. The 5mm slice CT scans were evaluated for the presence of appendicitis. The sensitivity, specificity and accuracy of CT were calculated. The negative appendectomy rate (NAR) was compared between the patients with CT scans and those without CT scans. Furthermore, the patients were classified into the children and adults groups and the male and female groups and the differences of the NARs were analyzed for each group. RESULTS: The sensitivity, specificity and accuracy were 95%, 93% and 94%, respectively. The NAR was lower for the patients with a CT scan (12%) compared to 27% for those patients without CT scans (P=0.002). The difference of the NAR between the preoperative CT group and the without CT group was statistically significant for the female (P=0.004) and adult groups (P=0.012) (14% vs 36%, 11% vs 26%, respectively). CONCLUSION: Preoperative intravenous contrast enhanced abdomen-pelvis CT was effective in reducing the negative appendectomy rate in patients who were suspected of having acute appendicitis. Especially, the adults and women benefit more from CT scanning and they had a significantly lower negative appendectomy rate than the children and men, respectively.

Pseudoaneurysm is one of the complications of arterial injuries by trauma. The case report in children is rare, although not in adult. A 7-year and 10-month girl was visited with the complaints of pain and a mass in her right leg. At first, the radiograph of right tibia showed a remarkable cortical erosion from without, suggesting mass effect by a soft tissue tumor. She had a history of fracture of right tibia, and then manipulative reduction and K-wire fixation at 11 months ago. Arteriography showed a formation of the pseudoaneurysm originated from the posterior tibial artery. The operation was done through the ligation of artery at proximal and distal to pseudoaneurysm, and then excision of mass. At 5 year follow-up, the configuration and function of right foot was normal. Eventually, the cause of the mass formation is thought by the trauma of fracture fragment at the time of accidents, but the possibility of penetrated injuries by K-wire should be ruled out, which is used frequently in children's fracture. We experienced a case of traumatic pseudoaneurysm of posterior tibal artery with tibial fracture, especially occurred in pediatric patient, and presented the result of long-term follow-up.

Spontaneous regression of intra-abdominal cystic tumors in adults is unusual. Here, we present the case of an apparently spontaneous regression of a large intra-abdominal cystic mass found in the postpartum period of an 18-year-old woman. The regression was demonstrated using serial computed tomography (CT) examinations over a two-year period.
