PURPOSE: Base on the concept of the Mac stitch, we designed the modified Mac-suture bridge technique to improve the outcome of arthroscopic repair of rotator cuff tear with poor tissue quality. Moreover, we evaluated both the radiological and clinical outcomes of the surgery to assess the effectiveness of the newly designed technique. MATERIALS AND METHODS: From January 2010 to December 2014, a total of 52 patients (25 males, 27 females) with rotator cuff tear, with poor tissue quality according to both radiological and intraoperative findings, who underwent arthroscopic rotator cuff repair using the modified Mac-suture bridge technique and followed-up for at least 1 year were included in this study. The mean patient age at the time of surgery was 60 years. The average follow-up period was 20 months. We evaluated the clinical outcomes by checking the range of motion and compared the following, both preoperatively and postoperatively: American Shoulder and Elbow Surgeon (ASES) score, University of California, Los Angeles (UCLA) score, Constant shoulder score (CSS), visual analogue scale (VAS). In addition, we analyzed 42 series of postoperative magnetic resonance imaging by using the Sugaya's classification for the evaluation of the repair integrity. RESULTS: All clinical scores showed significant improvement (ASES score improved from 56.75 to 83.44, UCLA score from 20.52 to 29.23, CSS from 64.04 to 80.90, and VAS from 6.17 to 1.62; p<0.001). The range of motion was also improved; forward flexion improved from 108° to 158°, abduction from 109° to 160°, external rotation from 27° to 50°, and internal rotation from 31° to 57° (p<0.001). Satisfactory radiologic results were noted on postoperative magnetic resonance imaging, consisting of 15 cases (35.7%) type I, 22 cases (52.4%) type II, 3 cases (7.1%) type III, 2 cases (4.8%) type IV, and no type V, according to the Sugaya's method. CONCLUSION: The modified Mac-suture bridge technique provided satisfactory results both radiologically and clinically for the treatment of rotator cuff tear with poor tendon tissue quality. It could possibly be a good alternative to previous techniques of arthroscopic repair.

The Angio-Seal is a widely used arterial closure device that helps achieve faster hemostasis and provide early ambulation to patients. However, it can cause various complications in clinical practice. We present the uncommon complication of popliteal artery occlusion following Angio-Seal deployment, and describe an effective interventional approach to its treatment. Because fluoroscopy-guided Fogarty embolectomy has the advantages of complete removal of the embolus without fragmentation, and clear visualization of the exact location of the embolus during the procedure, it is a suitable method for treating this complication.

PURPOSE: Most paraquat poisonings are easily diagnosed by history taking on physical examination, however, some are failed to be diagnosed initially if the poisoning was veiled. The purpose of this study was to explore the clinical characteristics of veiled paraquat poisoning. METHODS: We retrospectively reviewed the medical records of patients whose discharge diagnosis was paraquat poisoning in one university teaching hospital between 1 Jan, 2001 and 31 Dec, 2010. Veiled paraquat poisoning was determined when there was a positive urine paraquat kit in patients who did not mention paraquat poisoning in an initial physical examination or had unknown cause of pulmonary fibrosis, acute renal failure, or multi-organ failure. RESULTS: Of the 117 patients with paraquat poisoning during the study period, 6 patients (5.1%) had veiled paraquat poisoning. The clinical characteristics were 1) proteinuria - 6 (100%), 2) increased creatinine - 4 (66.7%), 3) green skin stains - 2 (33.3%), 4) mucosal ulcer - 3 (50%). Blood chemistry results were variable. CONCLUSION: We should suspect veiled paraquat poisoning for patients who have proteinuria, increased creatinine, green skin stain, mucosal ulcer and vomiting, or if they have rapidly progressing acute renal failure or multi-organ failure with unknown cause, even if patients didn't mention about paraquat poisoning upon the initial physical examination. In cases with the above clinical conditions, a thorough repeated physical examination including history taking and use of urine paraquat kits should be performed.

BACKGROUND: The prognosis of paraquat intoxication patients is poor and this makes the prediction of mortality important in administering aggressive treatment and admission. This article investigates the usefulness of simplified acute physiology score II (SAPS II), as a predictor of the mortality in paraquat intoxication. METHODS: We retrospectively reviewed 65 patients who were admitted in one hospital between January in 2005 and December in 2010. We calculated their SAPS II, serum paraquat level, and severity index of paraquat poisoning (SIPP) at the time of intensive care unit (ICU) admission. We investigated the relationship between each systems and the mortality. RESULTS: Overall mortality was 73.8%: 48 out of 65 patients died. Non-survived group (n = 48) had a higher SAPS II score (30.44 +/- 15.99) than survived group (n = 17 [15.7 +/- 6.26], p < 0.001). Serum paraquat level and SIPP were significantly higher in non-survived group than in survived group (p < 0.05, in all comparisons). By using the area under receiver operating characteristic curves (AUC), the SAPS II system yielded equal discriminative power (AUC = 0.82) with serum paraquat level (AUC = 0.896) and SIPP (AUC = 0.865). Hosmer-Lemeshow goodness-of-fit test C indicated SAPS II score validated well in paraquat intoxication group (p = 0.33). CONCLUSIONS: Serum paraquat level is the best way for prediction of mortality in patients with acute paraquat intoxication. If checking serum paraquat level is impossible or delayed, SAPS II score can be an alternative tool for evaluating the prognosis in paraquat intoxication.

Eosinophilic cholecystitis is a rare form of cholecystitis that is clinically indistinguishable from the predominant form of calculous cholecystitis. Histologically, it is characterized by a dense, transmural leukocyte infiltrate composed of more than 90% eosinophils. A 60-year-old woman complained of right upper quadrant pain. She had no allergic or medicine history. An abdominal CT scan revealed thickened gallbladder wall but no cholelithiasis, and a cholecystectomy was performed. Histologic examination showed transmural eosinophilic infiltration of the gallbladder wall.

Dieulafoy's lesion is a rare cause of repetitive and massive gastrointestinal bleeding, and this is characterized by an isolated arteriole protruding through a small mucosal defect. Dieulafoy's lesion is generally found in the stomach within 6 cm of the gastroesophageal junction, and usually on the lesser curvature, but many lesions have been reported in extragastric locations, including the esophagus, small bowel and rectum. A Dieulafoy's lesion in the ampulla of Vater is extremely rare, and only one such case has been reported in the Korean population. We experienced a rare case of Dieulafoy's lesion in the ampulla of Vater with massive pulsatile bleeding, and this was successfully treated by transparent cap-assisted endoscopic hemoclipping. We report here on this case with a review of the relevant literature.

BACKGROUND/AIMS: The detection of iatrogenic Mallory-Weiss syndrome during the course of upper GI endoscopy is apparently rare. The aim of this study was identify the clinical features of the disease and associated medical conditions. METHODS: We retrospectively analyzed 46 cases (0.08%) of iatrogenic Mallory- Weiss syndrome identified from 54,188 consecutive upper GI endoscopies performed at our institution during a period of 85 months. RESULTS: A total of 36 patients (78.2%) had retching or belching during the procedure. Hiatal hernias were noted in 20 patients (43.5%). We identified a difference of the attack rate by sex and age for iatrogenic Mallory-Weiss syndrome; the disorder developed predominantly in men. All of the patients had a mucosal tear and oozing and 16 patients underwent endoscopic hemostasis. After being diagnosed with iatrogenic Mallory-Weiss syndrome, 17 patients underwent follow- up endoscopy and all of the patients showed good results without rebleeding. No patient showed a complicated clinical course. CONCLUSIONS: A small number of patients had iatrogenic Mallory-Weiss syndrome and most of the patients showed a good prognosis. If there is a predictable risk factor identified during an upper GI endoscopy or an associated medical condition, special care needs to be taken to minimize belching or retching.

Anodic spark deposition method(ASD) surface treated titanium implant possesses a considerable osteoconductive potential that promoting a high level of implant osseointegration in normal bone. The purpose of this study was to observe the ASD implant's osseointegration in the osteoporosis-induced animal model. Twenty four rats, 10 weeks of age, were ovarectomized and 5 weeks later divided into two groups : ASD implant group and control implant group. Titanium screw implants (diameter; 2.0 mm, length, 3.5 mm; pitch-height, 0.4 mm) were designed for this study. Experimental implants were ASD treated and no treatment on control implants. ASD implants and control implants were placed in to left tibiae of rats. The rats were sacrificed at different time interval(1, 2, 4 and 8 weeks after implantation) for histopathologic observation and immunohisto -chemistrical observation, with collagen type I, fibronectin, integrin alpha2beta1 and integrin alpha5beta1 antibodies. The results obtained from this study were as follow: 1. Histopathologic findings, overall tissue response and the pattern of bone formation in both groups were similar. In ASD group, more newly formed bone was seen at 1 week and 2weeks than control group. 2. The levels of type I collagen and fibronectin expression were the most abundant at 2weeks and decreased gradually in both groups. Fibronectin and type I collagen expression in ASD group were stronger than control group but no significance. 3. The levels of integrin alpha2beta1 and Integrin alpha5beta1 expression were most abundant at 2 weeks and decreased gradually in both groups. No significant difference was observed in both groups. From this results, anodic oxidized titanium implants were more advantages in early stage of bone formation than control group, but have no significance in tissue responses and late bone formations. It could be stated that although anodic oxidized titanium implant possesses considerable osteoconductive potential but in osteoporotic bone condition dental implant procedure should performed after improving or treating the osteoporotic bone condition.

PURPOSE: The purpose of this study was to observe the effect of calcium and vitamin D to the titanium implant osseointegration in the osteoporosis-induced animal model. MATERIAL AND METHOD: Thirty-two rats, 10 weeks of age, were divided into two groups: experimental group was ingested additional calcium and vitamin D, and a control group was not. Titanium screw implant(diameter, 2.0 mm; length, 3.5 mm; pitch-height 0.4 mm) were placed into tibia of 32 rats, 16 in the control group and 16 in the experimental group. The rats were sacrificed at 1, 2, 4 and 8 weeks after implantation for histopathologic examination, histomorphometric analysis and immunohistochemistry with fibronectin and collagen type I antibody. RESULT: In histopathological findings, newly formed bone was seen at 2 weeks and became lamellar bone at 4 weeks, and mature trabecullar bone was seen at 8 weeks in experimental group. In control group, thickness of regenerated bone increased till 4 weeks gradually and trabecullar bone was seen at 8 weeks. In histomorphometric analysis, marrow bone density increased significantly in experimental group compared to control group. Fibronectin immunoreactivity was strong at 2 weeks in experimental group and reduced after 4 weeks gradually. But it was maintained continuously from 2 to 8 weeks in control group. Collagen type I immunoreactivity was very strong from 2 to 4 week in experimental group. And the amount of Collagen type I expression was more abundant in experimental group. CONCLUSION: The results of this study suggest that calcium and vitamin D supplementation promote bone healing around titanium implants in osteoporosis induced animals.
