Infection is one of the most serious complications following total hip replacement arthroplasty. Many modifications of procedures have been advocated in order to reduce the rate of infection with varying success. Incorporation of antibiotic to bone cement is one such approach. However, there still remains some reluctancy to adopt this method on account of dubious antibiotic effect at the expense of weakening of physical properties. Possible emergence of resistant organisms and hypersensitivity are additional drawbacks to be considered. The present experiments were undertaken to study the effectiveness of antibacterial activity of cement-antibiotic admixtures in vitro and in vivo as well as change of physical properties produced by the incorporation. As conclusions, antibiotic-mixed bone cements have evident effects on growth of inoculated organisms sensitive to added antibiotics whereas cured bone cement itself has been proved not to have any antibacterial activity. The leaching of antibiotics occurs fairly soon, the great majority of the amount within several days. The rest shows slow, delayed leaching over period of three weeks. The weakening of physical properties was not so significant to forbid the application. Resistance to tensile and bending stress was more reduced than that to compression stress. The mixing of two antibiotics(Cephaloridine and Gentamicin powder) together to bone cement revealed double-edged effectiveness to either of gram-positive or negative organisms without any significant illeffects on hardness of cured cement, It is suggested that mixture of two antibiotics to bone cement renders broader blind coverage to unknown causative micro-organisms of postoperative deep infection of total hip replacement arthroplasty.

The congenital tracheoesophageal fistula without atresia of the esophagus is considered a rare variant, and the literature concerned to the tracheoesophageal fistula fistula without atresia is little in adult especially. The 22-year-old male was admitted to Yeungnam University Hospital with his chief complaints of weight loss (6 kg/6 months), abdominal discomfort, and intermittent coughing. The diagnosis was made by the endoscopy and esophagography. The fistula was 1.5 cm in diameter, 0.5 cm in length. The level was around second thoracic vertebra. The operation was performed transpleurally through the right third intercostals space and the fistula was secured with interrupted silk suture after division. The fibrotic adhesion was seen around the tracheoesophageal fistula. The postoperative course was uneventful, and postoperative esophagogram revealed no extraluminal leakage. Herewith we report this unusual case of isolated tracheo-esophageal fistula with review of literatures.

BACKGROUND: We compared the clinical outcomes of cardiac valve surgery in adult Jehovah's Witness patients refusing blood transfusion to those in non-Jehovah's Witness patients without any transfusion limitations. METHODS: From 2005 to 2014, 25 Jehovah's Witnesses (JW group) underwent cardiac valve surgery using a blood conservation strategy. Twenty-five matched control patients (non-JW group) were selected according to sex, age, operation date, and surgeon. Both groups were managed according to general guidelines of anticoagulation for valve surgery. RESULTS: The operative mortality rate was 4.0% in the JW group and 0% in the non-JW group (p = 1.000). There was no difference in postoperative major complications between the groups (p = 1.000). The overall survival rate at 5 and 10 years was 85.6% ± 7.9% and 85.6% ± 7.9% in the JW group, respectively, and 100.0% ± 0.0% and 66.7% ± 27.2% in the non-JW group (p = 0.313). The valve-related morbidity-free survival rates (p = 0.625) and late morbidity-free survival rates (p = 0.885) were not significantly different between the groups. CONCLUSIONS: Using a perioperative strategy for blood conservation, cardiac valve surgery without transfusion had comparable clinical outcomes in adult patients. This blood conservation strategy could be broadly applied to major surgeries with careful perioperative care.

The usefulness of microscopic examination of pure bile directly collected from the biliary tract during endoscopic retrograde cholangiography and without hormonal stimulation was evaluated in 86 patients. Cholesterol monohydrate crystal and/or calcium bilirubinate granule were observed in the bile of 64% of GB stones, 88% of CBD stones and l00% of IHD stones. But only 4% of non stone control group were positive crystals examinations. According to this results, microscopic examinations:of bile samples collected during endoscopic retrograde cholangiography exhibited a sensitivity and a specificity for cholelithiasis recognition of 82.3% and 95.8%, respectively, with a positive and negative predictive value of 98.1% and 67.6%, respectively. We conclude that microscopic bile examinations of bile samples collected during ERC is useful to investigate in patients with suspected cholelithiasis.
