Closed medullary nailing has become increasingly popular in the management of fractures of the femur because of a high rate of union, a low rate of complications, and excellent return of function. But it requires good facility and excellent surgical skill. The authors experienced two cases of iatrogenic femur neck fracture during closed medullary nailing of femur shaft fracture.

The 8 cases of left ventricular thrombus detected by the 2 D echocardiography or left ventriculography, after acute transmural anterior myocardial infarction were effectively lysed by the thrombolytic agents and heparin therapy. The thrombolytic agents were either urokinase or tissue plasminogen activator. Urokinase was infused intravenously at a dose of 1.0 million unit for three days. And tissue plasminogen activator was infused at a dose of 100mg for a day. In all cases, the thrombi were completely lysed. At follow up, no recurrence of left ventricular thrombus was found. We have experienced 2 cases of peripheral embolization in which, left ventricular thrombi were protruding nonmobile type. The one was the embolic cerebral infarction, the other was transient hoarseness and paresthesia on the left foot, which may be transient ischemic attack. These results show that left ventricular thrombi can be treated by intravenous thrombolytic agents without life-threatening complication. However, for the better establishment of the risk and benefit of therapy further investigation is needed.

PURPOSE: To evaluate the efficiency of a surgical method using original breaks to drain subretinal fluid without using retinotomy and perfluorocarbon liquid for patients with rhegmatogenous retinal detachment (RRD). METHODS: A retrospective chart review comparing 41 eyes of 41 patients who received vitrectomy, and used original breaks to drain subretinal fluid without using perfluorocarbon liquid, and 40 eyes of 40 patients who received vitrectomy using perfluorocarbon liquid for simple RRD between February 2014 and December 2017 was conducted. All patients were followed for a minimum of 6 months after surgery. RESULTS: The primary anatomical success percentages were 97.6% and 97.5% for groups that did not and did use perfluorocarbon liquid, respectively. Retinal detachment recurred in one eye from both groups. The final success percentage was 100%. The preoperative mean logMAR best-corrected visual acuity (BCVA) of 0.87 ± 0.80 improved to 0.30 ± 0.30 at postoperative 6 months for the group that did not use perfluorocarbon liquid, while it improved from 0.86 ± 0.71 to 0.42 ± 0.52 for the group that did use perfluorocarbon liquid. Both groups showed significant BCVA improvement (p < 0.01). There was no significant difference in the incidence of complications caused by the use of perfluorocarbon liquid. CONCLUSIONS: Using original breaks to drain subretinal fluid without perfluorocarbon liquid in cases with RRD may be an effective and safe surgical technique for functional and anatomical recovery without serious complications.

Purpose: To evaluate changes in central macular thickness (CMT) and subfoveal choroidal thickness (SFCT) after phacovitrectomy over a 2-year period in idiopathic epiretinal membrane (ERM) patients. Methods: The records of 52 idiopathic ERM patients (52 eyes) who underwent phacovitrectomy, without recurrence of the condition over a 2-year follow-up period, were reviewed retrospectively. Changes in CMT and SFCT, as measured by optical coherence tomography, were analyzed and compared with those of a normal control group over a 2-year period. Results: The mean preoperative CMT and SFCT were 425.67 ± 84.67 and 257.56 ± 90.13 μm, respectively. Postoperative CMT was reduced significantly to 372.17 ± 45.26 μm at 1 year and 363.15 ± 47.35 μm at 2 years (p < 0.001). SFCT at 1 and 2 years postoperatively was significantly reduced to 238.85 ± 84.85 and 230.31 ± 87.95 μm, respectively (p < 0.001). In the control group, there was no significant change in CMT; however, the SFCT decreased by 11.09 ± 22.36 μm during the 2-year follow-up (p = 0.007). In contrast, in the patient group, CMT and SFCT decreased by 62.52 ± 71.45 and 27.25 ± 41.97 μm, respectively, showing a significant difference from the control group (p < 0.001 and p = 0.043, respectively). Both before surgery and at 1 year postoperatively, the thinner the CMT, the better the best-corrected visual acuity (BCVA) (p = 0.010 and p = 0.018, respectively). A better postoperative BCVA at 2 years was associated with a thinner CMT and better BCVA before surgery (p < 0.001 and p < 0.001, respectively). Conclusions Following a phacovitrectomy procedure, ERM patients showed significant reductions in both the CMT and SFCT at the 2-year follow-up.

Purpose: To analyze the changes in subfoveal Haller layer thickness (SFHT), subfoveal choroidal thickness (SFCT), and central macular thickness (CMT) after intravitreal aflibercept injection. Methods: This was a retrospective analysis of 36 diabetic macular edema patients who underwent intravitreal aflibercept injection between December 2016 and June 2021. The SFHT, SFCT, and CMT before and 1 month after the injection were compared using spectral-domain optical coherence tomography. Results: Mean baseline SFHT, SFCT, and CMT were 214.28 ± 80.00 μm, 307.89 ± 96.30 μm, and 525.64 ± 133.24 μm, which were reduced 1 month after the injection to 199.56 ± 75.76 μm, 290.36 ± 94.63 μm, and 409.72 ± 98.45 μm, respectively (p = 0.001, < 0.001, and < 0.001, respectively). There was a significant correlation between baseline SFHT and 1-month post-injection best-corrected visual acuity (BCVA), while thicker subfoveal Haller layers before the injection were associated with better BCVA after the injection (ρ = −0.342; p = 0.041). Conclusions In diabetic macular edema patients, SFHT, SFCT, and CMT decreased significantly over 1 month after the first intravitreal aflibercept injection. Greater SFHT before the injection was a good short-term predictor of BCVA after injection.

Since Ender introduced the concepts of multiple flexible intramedullary nailing in 1970, Ender nailing has been mostly used in intertrochanteric fractures of the elderly patients, but it has been rarely used in younger patients because of serious complications such as shortening and external rotation deformity. Authors already contended that the incidence of such complications had intimate connection with the quality of bone, and accordingly with the age. To substantiate the contention, we analyzed thirty-four cases with more than one year follow-up among forty cases of intertrochanteric fractures treated with Ender nails during the period from 1982 to 1989. And the results are summarized as follows;1. The average age was 39 yrs., and the most common cause of fractures was fall from a height. 2. According to the Kyle et al. clsssification, stable fractures(type I & II ) were 13 cases(38%), and unstable fractures (type III & IV) were 21 cases(62%). 3. According to the Singh's index, the good in bone quality(Grade 4, 5, & 6) were 31 cases(91 %), and the poor(Grade 1, 2, & 3) were only 3 cases(9%). 4. Postoperative complications occurred in 6 cases(17%), which included ROM limitation of knee joint in three cases(9%), proximal migrations of nails in two(5%), and distal migrations of nails in one(3%). Among them, 4 cases required revisional operations. There was no case with apparent external rotation deformity over 20 and shortening over 2cm. 5. It is thought that, contradictory to common beliefs, Ender nailingis a safe method for intertrochanteric fractures of femur in younger patients with good bone quality, but requires some experiences and cautions to prevent such complications as external rotation deformity and shorterning.

The unicornuate uterus is a rare type of the anomalous uteri, which is caused by failure of development of one of the mullerian ducts. This condition is usually associated with various degrees of rudimentary uterine horn. The unicornuate uterus with rudimentary horn is susceptible to many gynecologic and obstetric complications. Urinary tract anomalies, pelvic endometriosis, primary infertility are claimed to be common complaints in women with unicornuate uterus. We have experienced a case of rudimentary uterine horn adenomyosis associated with agenesis of ipsilateral kidney, pelvic endometriosis in a 13 years old girl. So we report this case with a brief review of literatures.
