PURPOSE: To analyze the effect of the augmented lateral tarsal strip for the correction of the paralytic ectropion in leprosy patients. METHODS: Ten leprosy patients (16 eyelids) with exposed keratitis and lagophthalmos from paralytic ectropion underwent surgery of the augmented lateral tarsal strip. Preoperative and postoperative vertical palpebral aperture, marginal reflex distance, lagophthalmos, and anterior segment findings were recorded at 3 and 6 months after surgery. Postoperative symptomatic and functional improvements were assessed at 6 months after surgery. RESULTS: There was a significant reduction between preoperative and postoperative measurements for vertical palpebral aperture (3.1+/-0.4 mm), lower marginal reflex distance (2.1+/-1.0 mm), and lagophthalmos (2.0+/-1.2 mm). Eye irritation symptoms and lid functions were improved in all patients. In a survey, the symptomatic, functional satisfaction was achieved in 90% of patients. CONCLUSIONS: The augmented lateral tarsal strip is a sufficiently effective surgical procedure to be considered in the treatment of paralytic ectropion in leprosy patients.

Neuroendocrine tumor (NET) of the major duodenal papilla is a rare occurrence. However, that of the minor duodenal papilla is even rarer. To date, only a few cases have been reported. Herein, we present a rare case of NETs detected at the major and minor duodenal papilla synchronously, which were successfully treated with endoscopic papillectomy without procedure-related complication. To the best of our knowledge, this is the first report of this kind in the world. Photomicrograph of the biopsy specimen stained immunohistochemically for synaptophysin showed a positive reaction of tumor cells. All resection margins were negative. Further experience with more cases will be needed to establish the exact indication of endoscopic papillectomy for duodenal papillary NETs.

OBJECTIVE: The purpose of this study is to investigate the incidence of new compression and to analyze factors that influence the fractures in adjacent levels after percutaneous vertebroplasty (PVP). METHODS: This retrospective study examined 206 patients who had undergone PVP for single level osteoporotic or osteopenic compression fractures during the last seven years in our department. After PVP, the patients were observed for at least over one year, and 29 patients showed new additional compression fractures in adjacent levels. One hundred seventy seven patients who did not show additional compression fractures were analyzed as the control group. Statistical comparisons were performed between the groups, in terms of age, gender, bone mineral density, whether bisphosphonate (BPP) was treated, preoperative kyphosis, preoperative wedge angle, change in wedge angle, amount of bone cement, existence of intradiscal bone cement leakage, and initial fracture levels. RESULTS: The statistically significant factors that influence new compression fractures in adjacent levels after PVP were as follows: being female, initial thoracolumbar junction fracture, preoperative large kyphotic, preoperative large wedge angle, change in wedge angle, administration of BPP in osteopenia group, and intradiscal cement leakage. CONCLUSION: This study identified many factors that influence newly developed compression fractures in adjacent levels after PVP. Interestingly, the administration of BPP in osteopenia group had positive influence on new fractures in this study. Therefore, we recommend early administration of BPP to patients with osteopenia.

In order to observe the changes in left ventricular function during coronary artery occlusion and reperfusion, left anterior descending (LAD) coronary arteries in the anesthetized dogs were occluded for 1 hour and then reperfused for 4 hours. Hemodynamic indexes of global systolic and diastolic function and regional wall thickness changes as a regional contractile index were measured during occlusion and reperfusion. The results were as follows; 1) Indexes of global systolic function (left ventricular peak systolic pressure, peak positive dP/dt) and global diastolic function (peak negative dP/dt, time constant, left ventricular end-diastolic pressure) showed deterioration in early occlusion period (10-30 minutes) but gradually improved even if coronary occlusion persisted. Reperfusion did not induce significant changes except that peak positive dP/dt transiently deteriorated 30 minutes after reperfusion and left ventricular end-diastolic pressure decreased 1.5-2 hours after reperfusion. 2) Indexed of regional function (i.e, end-diastolic thickness and % systolic thickening of anterior left ventricular wall) deteriorated by 10 minutes' occlusion which persisted during the entire occlusion period. Reperfusion induced no significant improvement in regional contractile function compared with occlusion 60 minutes' data, which suggested reperfusion for 4 hours after 1 hour's LAD occlusion may be insufficient for the ischemic region to recover its contractility. 3) Reperfusion arrhythmia (ventricular tachycardia) was noted in most (6/9) of the dogs, one of which deteriorated into ventricular fibrillation and the others spontaneously converted to normal sinus rhythm.

BACKGROUND: The quality of cord blood largely depends on cell viability. Viability assessments using trypan blue or 7-aminoactinomycin (7-AAD) staining, which are commonly used methods, may not reflect early apoptosis of cord blood cells. We aimed to investigate early apoptosis in cord blood cells following elapsed time after collection using double staining with annexin V and 7-AAD and to compare the result with that of viability evaluation using trypan blue or 7-AAD staining. METHODS: Umbilical cord blood samples were obtained from 30 pregnant women at the time of delivery between July 2012 and March 2013. Viability of cord blood cells was determined at 0 (T0), 24, and 48 hr after collection by using trypan blue exclusion assay, 7-AAD staining, and 7-AAD/annexin V staining. RESULTS: Viabilities defined by 7-AAD/annexin V staining at T0, 24, and 48 hr after collection were respectively as follows: total nucleated cells, 92.8+/-4.5%, 78.4+/-7.8%, and 65.5+/-8.1%; mononuclear cells, 94.4+/-1.7%, 90.8+/-4.2%, and 84.2+/-6.7%; and CD34-positive cells, 92.4+/-3.0%, 90.7+/-4.7%, and 89.3+/-7.0%. The viability using trypan blue was more than 90% until 48 hr after collection. CONCLUSIONS: The mean viability of total nucleated cells using 7-AAD/annexin V staining decreased to less than 80% at 24 hr after collection; however, the viability of CD34-positive cells was more than 85% until 48 hr. Our study's data will provide useful information for the assessing the quality of cord blood products.

Although digital gangrene is an uncommon clinical feature, it may lead to serious complications, such as amputation. Therefore, it requires prompt evaluation and treatment. Digital gangrene is often seen in systemic sclerosis, but is rare in systemic lupus erythematosus (SLE). In SLE, digital gangrene results from vasculitis, vasospasm, and thromboembolism. Here, we report a 15-year-old male SLE patient who initially presented with digital gangrene, and present a review of the relevant literature.
