PURPOSE: To report a case of a recurrent macular hemorrhage that developed after surgical removal of the internal limiting membrane (ILM) for subintimal hemorrhage due to retinal macroaneurysm. CASE SUMMARY: A 75-year-old female was admitted to the hospital complaining of decreased vision in the left eye which had started 3 weeks previously. The best corrected visual acuity (BCVA) of the right and left eye was 0.7 and 0.03, respectively. The intraocular pressure (IOP) of the right and left eye was 10 mm Hg and 12 mm Hg, respectively. On the fundus examination, macular preretinal and subretinal hemorrhage was observed and a diagnosis of retinal arterial macroaneurym of the inferonasal major artery was made. Vitrectomy was performed. After indocyanine green dye staining, the sub-ILM hemorrhage was treated with removal of the ILM. At postoperative day 3, the annular chorioretinal folds were observed due to the hypotony (4 mm Hg). However, the absence of leakage was confirmed through the sclerotomy site. At postoperative day 8, recurrent submacular hemorrhage occurred and the hemorrhage was observed to have spread after intravitreal C3F8 gas injection and when the patient was placed in the prone position. At postoperative 4 months, the hemorrhage that had invaded the macular area was completely resolved. The BCVA was 0.3, respectively. CONCLUSIONS: When removing a sub-ILM hemorrhage due to retinal macroaneurysm, recurrent hemorrhage can occur especially in a patient with ocular hypotony, as in the present case report. Physicians should be aware of this possibility and the proper treatment the condition requires.

BACKGROUND: More than 90% of acute stroke patients have measurable cardiovascular sequelae, but we have been often overlooked in formal discussions of treatment. If we estimate the incidence of myocardial injury in patient with spontaneous SAH, we may figure the possibility of cardiac dysfunction in such patients. This study was designed to investigate the incidence of myocardial injury in patients with spontaneous SAH using cardiac troponin I(cTnI). METHODS: A prospective single emergency center study was performed to determined preoperative incidence of unrecognized cardiac injury in patients suffering spontaneous SAH. We include the spontaneous SAH patients who underwent serum measurements of the cardic troponin I immediately upon admission last six month period. ECG, CK, CK-MB and myoglobin were also performed at admission. We excluded the spontaneous SAH patients who had past history of myocardial ischemia and ECG abnormality. RESULTS: Fifty-two patients(34 females, 18 males) with spontaneous SAH were studied prospectively. 18 patients(34.6% of the total study population) had cTnI level above 0.5ng/ml. ECG was performed in 52 patients and was abnormal in 15 of the 52 patients(28.8%). CONCLUSION: The measurement of cTnI has provided physicians with a myocardial marker that has a cardiac sensitivity for cardiac injury equal to that of CK-MB yet with greater specificity. So, cardiac troponin I is useful to estimate the incidence of myocardial injury in patients with spontaneous SAH. And we may estimate the possibility of cardiac dysfunction in such patients. This knowledge will hopefully aid in the care and improve the outcome.

Many contraceptive methods have been developed over the years due to high demand. However, female contraceptive pills and devices do not work for all females due to health conditions and side effects. Also, the number of males who want to actively participate in family planning is gradually increasing. However, the only contraceptive options currently available to males are condoms and vasectomy. Therefore, many male contraceptive methods, including medication (hormonal and nonhormonal therapy) and mechanical methods, are under development. Reversibility, safety, persistence, degree of invasion, promptness, and the suppression of anti-sperm antibody formation are essential factors in the development of male contraceptive methods. In this paper, male contraceptive methods under development are reviewed according to those essential factors. Furthermore, the timeline for the availability of a new male contraception is discussed.

PURPOSE: The purpose of this study was to analyze the radiologic findings of primary epiploic appendagitis, with particular attention to the correlation of ultrasonographic, clinical, CT, MR and surgical findings. MATERIALS AND METHODS: Among 14 patients with primary epiploic appendagitis who presented with the rapid onset of a very localized pain and tenderness, we performed ultrasonography in all, CT in eight, and MRI in four of these eight. Surgery was performed in two patients. Follow-up examinations were performed using US, CT and MRI (n=2), US and CT (n=2), US alone (n=2), and with regard to clinical features (n=12). RESULTS: US performed in 14 patients revealed the presence in all of small, well-defined, ovoid, noncompressible hyperechoic (n=12) or isoechoic (n=2) solid masses attached to the colonic wall, without bowel wall change and without communication with bowel lumen. CT performed in 8 patients showed varying hyperattenuating fatty lesions in the same location in the abdomen, without other inflammatory process. MRI findings of four patients were helpful for further evaluation of internal architecture. CONCLUSION: In primary epiploic appendagitis, US findings were sufficiently characteristic to allow accurate diagnosis and valuable for the differential diagnosis of other acute conditions of the abdomen.

PURPOSE: To evaluate the usefulness of magnetic resonance imaging (MRI) for assessing fracture types and soft tissue injuries associated with tibial plateau fractures. MATERIALS AND METHODS: MRI was performed in 38 patients with tibial plateau fractures, each of which was classified according to the Schatzker system. We evaluated MR images and assessed the prevalence of each fracture type and accompanying soft tissue injuries. We also assessed whether ligamentous injury correlated with the extent of articular depression, splitting, and comminution. In 24 patients, diagnosis was based on MRI and operative or arthroscopic findings, and in 14 patients, on MRI alone. RESULTS: The totals of fracture types I, II, III, IV, V and VI were 4 (11 %), 15 (39 %), 6 (16 %), 4 (11 %), 4 (11%), and 5 cases (13 %), respectively. In 30 cases (79 %), there were associated ligamentous or meniscal injuries. Medial collateral ligaments and lateral menisci were injured in 17 (45 %) and 14 cases (37 %), respectively. Type II and IV fracture patterns were associated with soft tissue injuries in 14 of 15 cases (93 %) and 4 of 4 cases(100 %), respectively. As the extent of articular depression increased and the extent of bony comminution decreased, there was an increased prevalence of accompanying ligamentous injuries. CONCLUSION: In tibial plateau fractures, MR imaging is a useful diagnostic modality for the evaluation of both fracture type and accompanying ligamentous or meniscal injuries.

PURPOSE: To evaluate the significance of axial length, which is a known risk factor of retinal vein occlusion, we measured the axial lengthby using contact A-scan sonography and partial interferometry and compared the two values. METHODS: This study included 19 patients complaining of visual symptoms and who were diagnosed with unilateral retinal vein occlusion (RVO) with macular edema (ME). Affected eyes were classified as the study group, and healthy fellow eyes were classified as the control group. We measured the central macular thickness (CMT) and axial length (AL) of the affected and fellow eyes and compared them. CMT was measured by optical coherence tomography (Stratus OCT, Carl Zeiss, Jena, Germany), and AL was measured by interferometry (IOL Master®, Carl Zeiss, Jena, Germany). RESULTS: In RVO patients, CMT was significantly different between affected eyes (485.7 ± 111.3 µm) and fellow eyes (197.8 ± 29.7 µm; p < 0.001). Axial length measured by A-scan sonography was 23.06 ± 0.86 mm in the affected eyes and 23.28 ± 0.93 mm in the healthy eyes, which was statistically different (p < 0.001). However, using partial interferometry, the AL was 23.35 ± 0.87 mm in the affected eyes and 23.38 ± 0.95 mm in the healthy eyes. No significant difference was found. CONCLUSIONS: We confirmed that short AL, which was once thought to be a risk factor of RVO, results from the properties of the instruments used for measurement. Moreover, we verified that partial interferometry is more accurate for measurement of AL than A-scan sonography when retinal vein occlusion is associated with ME.

PURPOSE: To evaluate the visual outcome of combined phacoemulsification, intraocular lens implantation, and vitrectomy for macula-sparing rhegmatogenous retinal detachment. METHODS: The results of combined vitrectomy with cataract extraction were retrospectively analyzed in patients with preexisting cataracts and new-onset rhegmatogenous retinal detachment. To qualify, patients must also have had macular sparing in a region 6,000 microm in diameter on optical coherence tomography. The anatomical success rate, visual outcomes, and postoperative complications relating to visual acuity were evaluated. RESULTS: In 56 patients followed postoperatively for more than 12 months, the initial and final surgical success rate was 96.4% and 100%, respectively. The mean preoperative logarithm of the minimum angle of resolution visual acuity was 0.05 and decreased to 0.11 postoperatively (p < 0.001). Of the 56 patients, 20 (35.7%) had worse visual acuity postoperatively, compared with preoperatively (0.06 vs. 0.27, p < 0.001); these cases were comprised of six patients with epiretinal membranes, 12 patients with a posterior capsule opacity, and two patients with cystoid macular edema. In the remaining 36 patients, there were no significant differences in visual acuity preoperatively and postoperatively (0.04 vs. 0.03, p = 0.324). CONCLUSIONS: In patients with cataracts who develop macula-sparing rhegmatogenous retinal detachment and whose visual prognosis is excellent assuming the retina can be reattached successfully, combined phacoemulsification, intraocular lens implantation, and vitrectomy might be an effective treatment. However, the visual prognosis is significantly affected by postoperative complications such as an epiretinal membranes, posterior capsule opacity, and cystoid macular edema. Therefore, further studies should examine methods to prevent these postoperative complications.

Although, erythema nodosum is a common skin manifestation associated with syphilis, nodular vasculitis is a rare feature. Here, we describe a case of a 22-year-old, human immunedeficiency virus negative, non-immunocompromised man who developed recurrent oral and scrotal ulcers with nodular lesions of the lower extremitie. Behcet's disease was initially suspected, however, his serologic test for syphilis was positive, and he was thus diagnosed with secondary syphilis, with a skin biopsy showing nodular vasculitis. The patient was treated with benzathine penicillin, and the skin lesions disappeared after treatment.

OBJECTIVES: To compare the incidence of osteoporosis and the related factors among fracture sites in above 50 year-old patients with fractures caused by low-energy trauma. MATERIALS AND METHODS: Seven hundred and fourteen patients with fracture from low energy trauma were evaluated retrospectively. By the Dual-energy x-ray absorptionmetry, we measured bone mineral density (BMD) at lumbar spine and proximal femur, and compared the incidence of osteoporosis, age, sex, body mass index (BMI), previous fracture history, past osteoporosis medication history according to each fracture sites. RESULTS: BMD was decreased according to increasing age with statistical significance (P<0.001). Sex has no significant difference according to fracture site (P=0.141). Average age of patients with osteoporotic fracture was 73.8, 72.8, 66.3, 73.4, 78.3 years old according to fracture site as T-spine, L-spine, distal radius, proximal humerus and proximal femur, respectively. There was significant difference among groups (P<0.001). Average BMI related with osteoporotic fracture site was 22.9 kg/m2, 22.7 kg/m2, 23.4 kg/m2, 23.0 kg/m2, 21.7 kg/m2, respectively and it showed significant difference among groups (P<0.001). Average bone mass and T-score related with osteoporotic fracture site was 0.587 g/cm2 (-3.5), 0.614 g/cm2 (-3.1), 0.647 g/cm2 (-2.6), 0.597 g/cm2 (-3.1), 0.554 g/cm2 (-3.5), with significant difference among groups (P<0.001). Previous fracture history had no significant difference among groups (P=0.078). Previous osteoporosis medication history had significant difference among the groups (P<0.001). CONCLUSIONS: In low-energy traumatic fracture, age, BMI and previous osteoporosis medication history are significantly related factors with BMD and osteoporotic fracture. Early diagnosis of osteoporosis and osteoporotic medication use is effective for decrease incidence of low-energy osteoporotic fracture.
