PURPOSE: To report a case of a macular hole resulting from accidental exposure to tattoo removal by the Q-Switched Nd:YAG laser, which was treated successfully by vitrectomy and silicone oil infusion. CASE SUMMARY: A 33-year-old man presented with decreased visual acuity after accidental exposure to a Q-Switched Nd:YAG laser. According to fundus examination, vitreous hemorrhage and macular edema were observed. After 21 days, a macular hole had developed which was treated by standard pars plana vitrectomy and gas tamponade. Unfortunately, closure was not obtained on the first attempt. Therefore, a second attempt using silicone oil infusion was performed. Four months after the initial visit, BCVA had increased to 20/50, and anatomical occlusion was achieved. CONCLUSIONS: The authors of the present study experienced an unusual case of macular hole developed from the Q-Switched Nd:YAG laser used to remove a tattoo. A satisfactory visual acuity was achieved after silicone oil infusion despite failure in the first surgery.

A congenital ureteral valve is a rare disease, with the first case presented in 1887, since when, only 42 cases have subsequently been reported. From a review of the reported cases, this abnormality was often found to be associated with other urological disorders, such as vesicoureteral reflux, ectopic ureter, complete and incomplete duplication of the kidney, and contralateral renal atrophy. Here, the case of an adult patient with multiple congenital ureteral valves and renal atrophy is reported.

OBJECTIVE: Morphometric data for the lumbar posterior longitudinal ligament (PLL) was investigated to identify whether there is a difference in the morphometry of the PLL of the lumbar spine at each level with respect to the pattern of intervertebral disc displacement.METHODS: In 14 formalin-fixed adult cadavers (12 males and 2 females), from L1 to L5, the authors measured the width and height of the PLL and compared them with other landmarks such as the disc and the pedicle.RESULTS: Horizontally, at the upper margin of the disc, the central portion of the superficial PLL covered 17.8–36.9% of the disc width and the fan-like portion of the PLL covered 63.9–76.7% of the disc width. At the level of the median portion of the disc, the PLL covered 69.1–74.5% of the disc width. Vertically, at the level of the medial margin of the pedicle, the fan-like portion of the PLL covered 23.5–29.9% of the disc height. In general, a significant difference in length was not found in the right-left and male-female comparisons.CONCLUSION: This study presents the morphometric data on the pattern of intervertebral disc displacement and helps to improve the knowledge of the surgical anatomy of the lumbar PLL.

The common carotid artery is an artery which supplies the head and neck with oxygenated blood. Although unilateral common carotid artery occlusion or bilateral internal carotid artery occlusion have been reported, the incidence of both common carotid artery occlusion is very rare. As previous report which reviewed 5400 carotid duplex ultrasonograms, 2.5% of internal carotid artery occlusion, 0.24% of unilateral common carotid artery occlusion and none of bilateral common carotid artery occlusion were reported. Common carotid and subclavian arteries are important in the blood supply to the vasculatures of head and upper extremities. Bilateral common carotid artery occlusion might be a cause of stroke, transient ischemic attack or other neurologic sequalae. Cerebral oximetry is a simple method of measuring regional cerebral oxygen saturation (rSO2), which appears to reflect changes in cerebral perfusion and it has been increasingly applicated in many clinical situations such as vascular surgeries involving head/ neck and operations adopting cardiopulmonary bypass. This case describes a successful anesthetic management in a patient with occlusion of bilateral common carotid and subclavian arteries using continuous cerebral oxygenation monitoring during laparoscopic cholecystectomy.

The majority of cardiac myxoma occur sporadically as isolated lesions in the left atrium of middle-aged women. However, a familial form and a syndrome form of this lesion have also been identified. The syndrome myxoma can present itself with pigmented skin lesions and peripheral or endocrine neoplasms. The familial and syndrome forms of cardiac myxomas can usually be distinguished from the sporadic form by their occurrences at younger ages, their unusual locations, the multicentricity of the lesions, and the presence of rare pathological conditions. In addition, a higher rate of recurrent lesions is usually associated with the familial and syndrome forms of this disease. We present a case of complex cardiac myxoma with pigmented skin lesions and breast myxoma and report it with a review of literature.

Ischemic colitis is the most common vascular disorder of intestines, and usually affects older patients. Many predisposing conditions have been implicated in the pathogenesis of colonic ischemia, although many occurrences are spontaneous in nature. Ischemic colitis can induce a wide spectrum of radiological or endoscopic features, depending on the site, extend, and timing of its onset. The coexistence of colonic ischemia with carcinoma of large bowel is well documented. However It is less well recognized that a localized segment of ischemic colon can mimic a carcinoma. Here, we report a case of ischemic colitis mimicking colon cancer in a 66 year-old man.

PURPOSE: We evaluated the changes of storage symptoms after tension-free vaginal tape(TVT) procedures in stress urinary incontinence(SUI) patients, and we investigated the factors predicting the changes of storage symptoms. MATERIALS AND METHODS: From January 2000 to August 2003, 713 patients with SUI were operated on with using suburethral sling procedures(TVT). A follow-up study was conducted for over a one year period with 495 patients. We analyzed the one year outcomes of TVT surgeries and the changes of storage symptoms after TVT. RESULTS: The rates of cure and improvements at one year after TVT were 80.8% and 12.3%, respectively. At one month after TVT, 59 of 180(33%) patients with urgency before TVT were improved, and 60 of 72(83.6%) patients with urgency incontinence before TVT were improved. In 86 of 180(47.8%) patients, the urgency is improved, and in 65 of 72(90.1%) patients, the urgency incontinence disappeared at one year after TVT procedure. Urgency developed in 65 of the 243(26.9%) patients who had no urgency before TVT, but after 1 year, only 28(10.2%, 25/243) these 243 patients had urgency. 102(31.6%) of the patients with frequency before TVT were improved after TVT. Of the 92 patients with nocturia, 22 (23.4%) patients were improved. There were no statically significant factors predicting the changes of the storage symptoms. CONCLUSIONS: The total improvement rate (cure+improvements) of stress urinary incontinence was 93.1% at one year. We can expect the improvement of urgency(47.1%) and urgency incontinence(90.1%) after TVT procedures, but not improvement of the frequency and nocturia.

PURPOSE: This study reported patient outcomes of chemotherapy-induced nausea and vomiting (CINV) prophylaxis for highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC) regimens and evaluated its adherence to acute-phase CINV prophylaxis in the Korean population subset of the Pan Australasian Chemotherapy Induced Emesis burden of illness (PrACTICE) study. MATERIALS AND METHODS: This subgroup analysis evaluated 158 Korean patients receiving HEC or MEC and compared the data (wherever possible) with that of 648 patients from the Asia-Pacific (AP) region. Study endpoints included evaluation of primary CINV prophylaxis and adherence to acute-phase CINV prophylaxis in cycle 1 (American Society of Clinical Oncology [ASCO] Quality Oncology Practice Initiative [QOPI]). RESULTS: In South Korea and the AP, a 5-hydroxytryptamine-3 receptor antagonist (5HT₃-RA) prophylaxis for the acute phase was administered to 79/80 patients (98.8%) for HEC and 70/71 patients (98.6%) for MEC regimens (QOPI-1). Triple regimen (corticosteroid–5HT₃-RA–neurokinin 1-RA) was initiated in 46/80 patients (57.5%) for prophylaxis of acute CINV in cycle 1 of HEC (QOPI-3). Double regimen (corticosteroid–5HT₃-RA, with or within NK₁-RA) was initiated in 61/71 patients (83.1%) for control of acute CINV in cycle 1 of MEC a(QOPI-2). CONCLUSION: Active management of CINV is necessary in cycle 1 of HEC in South Korea, despite higher rates than the AP region. Adherence to the international guidelines for CINV prophylaxis requires attention in the acute phase in cycle 1 of the HEC regimen.

The purpose of this study was to evaluate feasibility of Vertical Multileaf Collimator for determination of irradiation size using Vertical Multileaf Collimator and lead block to determine 4 different irradiation shape in case of Co-60 gamma-ray and 6 MV X-ray. We chose ion chamber, glass dosimeter and EBT chromic film to compare with Vertical Multileaf Collimator results and lead block results. In case of Co-60 gamma-ray and 6 MV X-ray, the central axis point dose normalized at reference field of lead block with ion chamber results for Vertical Multileaf Collimator were estimated higher than lead block about 5.1%, 4.2%. In case of Co-60 gamma-ray, the central axis point dose normalized at reference field of lead block with glass dosimeter results for Vertical Multileaf Collimator were estimated higher than lead block about 2.2%, 7.8%, 7.2%, 4.0% for reference, circle, triangle, cross field, respectively. In case of 6 MV X-ray, the central axis point dose normalized at reference field of lead block with glass dosimeter results for Vertical Multileaf Collimator were estimated higher than lead block about 6.7%, 6.2%, 3.8%, 6.2% for reference, circle, triangle, cross field, respectively. The results of EBT chromic film, Vertical Multileaf Collimator of penumbra size for all irradiation shape was smaller than lead block of those size that 2.0~3.5 mm for Co-60 gamma-ray, 0.5~1.0 mm for 6 MV X-ray. The results from this study, radiation treatment volume that results in shielding block can be minimized. In addition, during radiation treatment for 2, 3-dimensional radiation therapy using a Vertical Multileaf Collimator of this survey can be used to determine variety of irradiation fields.
