BACKGROUND: We investigated the risk factors for the recurrence of anterior shoulder instability after arthroscopic surgery with suture anchors and the clinical outcomes after reoperation. METHODS: A total of 281 patients (February 2001 to December 2012) were enrolled into our study, and postoperative subluxation and dislocation were considered as recurrence of the condition. We analyzed radiologic results and functional outcome including the American Shoulder and Elbow Surgeons Evaluation Form, the Korean Shoulder Society Score, and the Rowe scores. RESULTS: Of the 281 patients, instability recurred in 51 patients (18.1%). Sixteen out of 51 patients (31.4%) received a reoperation. In terms of the functional outcome, we found that the intact group, comprising patients without recurrence, had a significantly better functional outcome than those in the recurrent group. The size of glenoid defect at the time of initial surgery significantly differed between intact and recurrent group (p<0.05). We found that the number of dislocations, the time from the initial presentation of symptoms to surgery, and the number of anchor points significantly differed between initial operation and revision group (p<0.05). The functional outcome after revision surgery was comparable to intact group after initial operation. CONCLUSIONS: Eighteen percent of recurrence occurred after arthroscopic instability surgery, and 5.6% received reoperation surgery. Risk factors for recurrence was the initial size of glenoid defect. In cases of revision surgery, good clinical outcomes could be achieved using additional suture anchor.

BACKGROUND: Laryngoscopy and tracheal intubation for general anesthesia are potent stimuli to the cardiovascular system due to sympathetic stimulation. The aim of this study was to compare the hemodynamic responses with different administration routes of lidocaine on blood pressure and heart rate changes associated with tracheal intubation. METHODS: Sixty patients were randomly assigned to spray group (Group 1, n=20) received 10% lidocaine 1.5 mg/kg spray to intratracheally immediately before tracheal intubation, IV group (Group 2, n=20) received 2% lidocaine 1.5 mg/kg intravenously before 90 sec tracheal intubation and control group (Group 3, n=20). Anesthesia was induced with thiopental 5 mg/kg IV, vecuronium 0.1 mg/kg and 50% N2O-O2- 2vol % enflurane. After 5 minutes, tracheal intubation was performed. Mean arterial pressure and heart rate were measured at preintubation and immediately postintubation, 1, 3, 5 mins after tracheal intubation. RESULTS:The differences of mean arterial pressure which were measured at preintubation and immediately postintubation and 1 minute after intubation in group 1 were significantly lower than those in other group (p<0.05). The differences of heart rate which measured at preintubation and 1 minute after intubation were lower than those in group 3 (p<0.05). CONCLUSIONS: For the suppression of sympathetic stimulation following tracheal intubation, 10% lidocaine spray to the laryngotrachea is an effective method to suppress cardiovascular response.

The mucormycosis is a group of serious opportunistic infections caused by fungi of the class Zygomycetes and order Mucorales. Pulmonary mucormycosis is a relatively rare disease but typically manifested by a rapidly progressive, often fatal pneumonia in patients with diabetes mellitus, hematologic malignant neoplasms, or organ transplants. The radiologic manifestations of pulmonary mucormycosis are nonspecific and include progressive lobar or multilobar consolidations, pulmonary masses and pulmonary nodules. Recently, we experienced a pulmonary mucormycosis in 32-year-old man with uncontrolled diabetes. He complained of cough, left pleuritic chest pain and generalized weakness. Initial chest X-ray finding was the consolidation on the lower lobe of the left lung. On the sixth hospital day, bronchoscopic examination with lung biopsy revealed broad, non-septate hyphae with right-angle branching, diagnostic of mucormycosis, and consequently amphotericin B therapy was started. We performed a lobectomy of the left lower lobe of the lung on 29th hospital day.

BACKGROUND: Although impaired endothelial function is well known in patients with diabetes mellitus, the precise mechanism and the factors that contribute to this dysfunction remain to be clarified. We examined the effect of acute hyperglycemia on patients with impaired glucose metabolism in vivo by plethysmography. METHODS: Seven patients with diabetes mellitus or impaired glucose metabolism were studied. In each patient, endothelial function was examined in the fasting state and at two levels of hyperglycemia, which were achieved by the infusion of glucose, insulin, and somatostatin. Forearm blood flow was measured while acetylcholine was infused in increasing concentrations(7.5, 15, and 30 microgram/min) through the brachial artery. RESULTS: Glucose concentrations increased accordingly at each stage, from 135.3+/-18.4 mg/dl at stage 1(the fasting state), to 239.0+/-15.2 mg/dl at stage 2(the first level of hyperglycemia), and to 378.3+/-25.3 at stage 3 (the second level of hyperglycemia) [p<0.01]. Maximal acetylcholine-dependent vasodilation achieved by infusion of acetylcholine at 30 microgram/min was significantly aftenuated during stages 2 and 3 compared with stage 1(p<0.05 by AVOVA; forearm blood flow ratio was 2.87+/-0.18 and 2.56+/-0.14 versus 3.58+/-0.21, respectively). This was also evident during the infusion of 15 microgram/min and 7.5 microgram/min of acetylcholine. CONCLUSIONS: Endothelium-dependent vasodilation is significantly aftenuated by acute hyperglycemia in patients with diabetes mellitus or impaired glucose metabolism. Our findings suggest that elevated glucose may contribute to the endothelial dysfunction observed in patients with diabetes mellitus or impaired glucose metabolism.

OBJECTIVES: The most common chromosomal abnormality contributing to recurrent abortion is the balanced chromosomal translocation. However the exact incidence of fetal losses are still unknown. The objectives of this study were to evaluate the incidence of fetal chromosomal abnormalities and outcome of pregnancy in recurrent miscarriage couples with balanced translocation. DESIGN: A retrospective analysis of recurrent spontaneous abortion patients with balanced chromosomal translocation. MATERIALS AND METHODS: Cytogenetic analysis was performed in 56 couples with history of recurrent abortions from 1995 to 1999. The use of high resolution banding technique and fluorescent in situ hybridization (FISH) in the chromosomal analysis has made the precise evaluation of chromosome aberrations. RESULTS: Among 56 couples, 42 patients had reciprocal translocation and 14 had Robertsonian translocation. Chromosomal aberrations were more frequent in women (36 cases) than in men (20 cases). Prenatal cytogenetic analyses were carried out in 14 subsequent pregnancies for carrier couples with balanced translocation. The fetal karyotypes showed that 5 cases (35.7%) was normal, 8 (57.1%) were balanced translocation, and 1 (7.1%) was unbalanced translocations. And cytogenetic analyses were done on 15 subsequent chorionic villi samples of abortuses for carrier couples with balanced translocations. Fourteen of fifteen abortuses (93.3%) were abnormal karyotype. CONCLUSIONS: Although the incidence of chromosomal imbalance in the fetuses was relatively low in prenatal cytogenetic analysis, individuals with balanced translocations are predisposed to giving birth to malformed offsprings with chromosomal imbalance (partial trisomy or monosomy). Therefore we recommend preimplantation genetic diagnosis (PGD) for recurrent abortions with balanced translocation and preventing the birth of offspring with chromosomal abnormalities.

Single staged posterior approach was carried out for three patients of dumbbell shaped schwannomas at the cervical region. Gross total resection was achieved in all of the patients, using a modified posterior midline exposure with hemilaminectomy and complete unilateral facetectorny. This exposure provided contiguous intraspinal, foraminal and extraforaminal access delete up to 2-3cm from lateral dural margin. The vertebral artery could be safely preserved from tumor mass. Although the follow up period is short, three patients showed no postoperative cervical spinalies from these operation. Illustrations of this approach with its possible application is discussed.

Paragonimiasis caused by Paragonimus westermani is essentially a pulmonary disorder, but it is also known to cause ectopic parasitism at various sites in human host such as the brain, muscle, liver, spinal cord and spleen. Ectopic parasitism of the female genital tract, especially the ovary is relatively rare. We have experienced a case of a 62-year-old Korean woman with asymptomatic ectopic paragonimiasis in the salpinx , ovary, and cul de sac.
