Significant illnesses or a major trauma including spinal cord injury can induce the changes of thyroid hormone metabolism, leading to the findings of "Euthyroid Sick Syndrome(ESS)". The physicians should be aware of these changes in order to interpret thyroid function test correctly after the spinal cord injury. We report three cases of ESS after the spinal cord injury. On a routine evaluation, they showed a low serum T3 level, and the T3 level returned to the normal range on a follow up study without any specific treatment.

Coronary stent embolization is a rare event but may result in clinically relevant cardiac ischemia or peripheral embolization during the procedure. We report a case of systemic embolizations of two coil stents during the primary PTCA in acute myocardial infarction, who were treated successfully with a double wire helix technique and a gooseneck snare. Although in our experience this rare complication did not produce any clinical complications, care should be taken to prevent this possibility, especially in patients with significant vessel tortuosity, calcification, total occlusion, or mild stenosis proximal to the target lesion.

Surgical endarterectomy has been shown to be superior to medical treatment in the management of severe carotid stenosis. Endarterectomy, although effective, does have limitations, and percutaneous transluminal angioplasty with stent may offer an alternative modality of treatment. We report on a patient with severe coronary disease that femoral arterial cannulation was not possible due to aorto-femoral shunt operation and absent pulse. The transradial approach was used for aortography, bilateral carotid angiography and successful elective stent deployment in the left internal carotid artery. The transradial approach might be useful alternative in case of problems with femoral approach.

BACKGROUND: Anatomic tunnel positioning is important in anterior cruciate ligament (ACL) reconstructive surgery. Recent studies have suggested the limitations of a traditional transtibial technique to place the ACL graft within the anatomic tunnel position of the ACL on the femur. The purpose of this study is to determine if the 2-incision tibial tunnel-independent technique can place femoral tunnel to native ACL center when compared with the transtibial technique, as the placement with the tibial tunnel-independent technique is unconstrained by tibial tunnel. METHODS: In sixty-nine patients, single-bundle ACL reconstruction with preservation of remnant bundle using hamstring tendon autograft was performed. Femoral tunnel locations were measured with quadrant methods on the medial to lateral view of the lateral femoral condyle. Tibial tunnel locations were measured in the anatomical coordinates axis on the top view of the proximal tibia. These measurements were compared with reference data on anatomical tunnel position. RESULTS: With the quadrant method, the femoral tunnel centers of the transtibial technique and tibial tunnel-independent technique were located. The mean (+/- standard deviation) was 36.49% +/- 7.65% and 24.71% +/- 4.90%, respectively, from the over-the-top, along the notch roof (parallel to the Blumensaat line); and at 7.71% +/- 7.25% and 27.08% +/- 7.05%, from the notch roof (perpendicular to the Blumensaat line). The tibial tunnel centers of the transtibial technique and tibial tunnel-independent technique were located at 39.83% +/- 8.20% and 36.32% +/- 8.10%, respectively, of the anterior to posterior tibial plateau depth; and at 49.13% +/- 4.02% and 47.75% +/- 4.04%, of the medial to lateral tibial plateau width. There was no statistical difference between the two techniques in tibial tunnel position. The tibial tunnel-independent technique used in this study placed femoral tunnel closer to the anatomical ACL anteromedial bundle center. In contrast, the transtibial technique placed the femoral tunnel more shallow and higher from the anatomical position, resulting in more vertical grafts. CONCLUSIONS: After single-bundle ACL reconstruction, three-dimensional computed tomography showed that the tibial tunnel-independent technique allows for the placement of the graft closer to the anatomical femoral tunnel position when compared with the traditional transtibial technique.

The authors analysed 2,653 cases of transthoracic fine needle aspiration cytology of the lung to evaluate the diagnostic accuracy and its limitation. A comparison was made between the original cytologic and the final histologic diagnoses on 1,149 cases from 1,074 patients. A diagnosis of malignancy was established in 38.3% benign in 48.1%, atypical lesion in 2.3%, and inadequate one in 11.9% of the cases. Statistical data on cytologic diagnoses were as follows; specificity 98.9%: sensitivity of procedure, 76.8%: sensitivity of diagnosis, 95.5%: false positive 5 cases: false negative 18 cases: predictive value for malignancy, 98.8%: predictive value for benign lesion, 79.5%: overall diagnostic efficiency, 87.5%: typing accuracy in malignant tumor, 80%.

US-guided large-gauge core needle biopsy has replaced fine-needle aspiration and excisional biopsy for sampling suspicious breast lesions. The core needle biopsy has many advantages: it is relatively simple, it can be done with local anesthesia, it enables accurate targeting under sonographic guidance and it leaves no scar. However, one rare disadvantage of this technique is the possible seeding of malignant cells along the needle track. We report here on a case of gross track seeding in a 76-year-old woman, and this was observed 70 days after performing a 14-gauge core needle biopsy.

Primary vesical actinomycosis is an extremely rare disease. In most cases it is misdiagnosed as vesical or urachal tumor and usually diagnosed through post-operative pathologic confirmation. Here we report a case of primary vesical actinomycosis confirmed by preoperative repeated multiple transabdominal biopsies. The patient was a 49-yr-old woman who presented with frequency, dysuria, and intermittent gross hematuria for 2 months. Computed tomography and cystoscopic examination showed broad-based, edematous, and protruding mass at the dome and anterior portion of the bladder. The clinical and imaging findings of the patient initially suggested vesical malignancy. Transurethral resection and multiple biopsies of the mass were performed. Pathologic examination demonstrated fibrosis with chronic inflammation. We performed repeated transabdominal multiple needle biopsies for further pathologic confirmation. Histopathologic examination demonstrated typical sulfur granules, which were consistent with actinomycosis.

BACKGROUND AND OBJECTIVES: Practical concerns about transradial approach are increasing in consideration of high procedural success rate, low local complications, and patient's convenience. There was no available data about repeated-use of radial artery for coronary procedures. We evaluate the changes of radial arterial diameter and procedural outcomes of repeated transradial procedure. MATERIALS AND METHOD: Of consecutive 1771 transradial coronary procedures, 117 patients received repeated transradial procedures through the same radial artery. Radial arterial diameter, vascular access time and procedural outcomes were evaluated in between the group of first-use and repeated-use of radial artery. RESULTS: Among 117 patients of second transradial coronary procedure in the repeated-use group, 47 patients (41.6%) underwent coronary intervention and 66 patients (58.4%) underwent coronary angiography. The right radial approach was used in 82.9% of the cases. There was no significant difference in radial artery mean diameter between pre-procedure and 1 day after procedure in patients with first-use and repeated-use group. There was no significant change of radial arterial diameter after first-use depending on the SAR (the ratio of sheath outer diameter to radial artery inner diameter). However, after repeated-use of radial artery, there was significant reduction of radial arterial diameter 1 day after procedure in the patients with SAR more than 0.9 (p<0.05). In repeated-use group, the mean radial arterial diameter was 2.63 +/- 0.35mm mm before the procedure and 2.51 +/- 0.29mm during follow-up (136 +/- 123 days) (p<0.05). There was no significant difference of the vascular access time between the first-use and repeated-use procedures (2.9+/-3.1 vs 3.3+/-3.6 minutes, p<0.05). The procedural success and vascular complication rate of repeated-use of radial artery were as similar to those of the first-use, but total occlusion of radial artery was higher in the repeated-use group (2.6% vs 0.7%, p<0.05). CONCLUSION: The diameter of radial artery after transradial procedures was significantly reduced during follow-up and the incidence of asymptomatic radial artery occlusion was more frequent after repeated-use. However, repeated-use of radial artery was feasible in most patients with high procedural success rate and low vascular complications.

The roles of TGF-beta1, beta2 and beta3 according to gestational ages and histodifferentiation were studied using immunohistochemistry with rat fetuses. 1. From day 14 to 21 of fetal rat, all the TGF-beta1, beta2 and beta3 were expressed in endocardium, myocardium, bronchiole, tunica intima of blood vessles, mucosa and serosa of intestine, striated muscle, hepatic capsule, hepatic hemopoietic cells, meninges, epidermis and dermis. 2. From day 14 to 21 of fetal rat, TGF-beta1 was not expressed in the smooth muscle of blood vessel and intestinal tract, alveolar cell and renal tubular cell. TGF-beta2 was not expressed in the smooth muscle of blood vessel and intestinal tract and alveolar cell. TGF-beta3 was not expressed in osteocyte, alveolar cell, and basement membrane of renal cuboidal epithelial cell. And TGF-betas expressed especially in early or late gestational age and the degree of expression increased or decreased with gestational age. 3. The TGF-beta1, beta2 and beta3 were expressed in tissues originated from 3 germ layers except several tissues, and those originated from mesoderm exhibited strong expression. The TGF-beta1 was expressed more widely than TGF-beta2 and beta3 during gestation. In summary, TGF-beta1, beta2 and beta3 were considered as important control factors of cell to cell interaction in the morphogenesis of tissues during fetal development.

BACKGROUND: Cortical suspensory femoral fixation is commonly performed for graft fixation to the femur in anterior cruciate ligament (ACL) reconstruction using hamstring tendons. The purpose of this study was to compare graft healing in the femoral tunnel, implant-related failure, and clinical results between fixed- and adjustable-length loop devices in outside-in ACL reconstruction. METHODS: A total of 109 patients who underwent ACL reconstruction using the outside-in technique from December 2010 to July 2014 were included. For femoral graft fixation, a fixed-length loop device was used in 48 patients (fixed-loop group) and an adjustable-length loop device was used in 61 patients (adjustable-loop group). For evaluation of graft healing in the femoral tunnel, magnetic resonance imaging was performed at postoperative 6 months and the signal-to-noise ratios (SNRs) of the tendon graft and tendon-bone interface in the femoral bone tunnel were evaluated. The presence of synovial fluid was evaluated to determine loop lengthening at the femoral tunnel exit. Clinical results assessed using International Knee Documentation Committee score, Tegner-Lysholm Knee Scoring scale, and knee instability tests were compared between groups. RESULTS: The SNRs of the tendon graft and tendon-bone interface were not statistically different between groups. The presence of synovial fluid at the femoral exit showed no statistical difference between groups. Clinical results were not significantly different between groups. CONCLUSIONS: The adjustable-length loop device provided comparable graft healing, implant-related failure, and clinical results with the fixed-length loop device, allowing adaptation of the graft to the different tunnel lengths. Therefore, it could be effectively used with an adjustment according to the femoral tunnel length.
