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.

Bilateral trans-scaphoid perilunate fracture dislocations are uncommon and have been rarely reported in the literature. Furthermore, it is more difficult to manage in the case of Fenton's syndrome (scaphocapitate fracture syndrome, trans-scaphoid trans-capitate fracture dislocation). These injuries occur after a high-energy trauma caused by fall from height or vehicular accidents. These fracture dislocation patterns have very few reported cases in the literature and little information as to the diagnosis, management, and surgical approach for treatment. We present a case of scaphocapitate fracture syndrome on the right hand and trans-scaphoid trans-triquetral perilunate injury on the left hand at the same time.

BACKGROUND: Plasmodium vivax circumsporozoite protein (CSP), merozoite surface protein (MSP) and Duffy binding protein (DBP) are functionally important conserved proteins and may have an important role in developing antigens. The aim of this study was to develop recombinant CSP, MSP, and DBP antigens, to evaluate their diagnostic usefulness, and to analyze the prevalence of seroreactivity against P. vivax in five different regions in Korea. METHODS: To construct recombinant CSP, MSP, and DBP antigens from P. vivax, DNA obtained from specimens previously diagnosed as P. vivax was used. To evaluate diagnostic usefulness of recombinant CSP, MSP, and DBP antigens from P. vivax, sera from 45 patients with P. vivax and 48 normal controls including 4 patients with Plasmodium falciparum were used. For the epidemiologic study, a total of 1, 014 serum samples obtained from five different regions in Korea were used. RESULTS: The sensitivity of the IgG antibody against the P. vivax recombinant CSP, MSP, DBP antigens and the antigens mixture of these proteins were 75.6%, 62.2%, 68.9%, and 97.8%, and the specificity were 92.1%, 84.2%, 81.6%, and 97.4%, respectively. The seropositivity against P. vivax recombinant antigens was highest in Cheolwon province. The IgG seropositivity against P. vivax recombinant CSP, MSP and DBP was 2.0%, 1.2%, and 1.5%, respectively. There were no significant differences in seroreactivity against P. vivax between each recombinant protein and each five different regions in Korea. CONCLUSIONS: Newly constructed recombinant CSP, MSP and DBP were useful in the detection of antibodies against the P. vivax antigen.

PURPOSE: The purpose of this study is to determine whether or not a patient's results are improved after removal of an internal fixative from a patient with no related symptoms. MATERIALS AND METHODS: This prospective study included 87 patients who agreed to participate in the study and satisfied the criteria for selection and exclusion of patients who underwent the operation for removal of internal fixative due to broken bones from March 1st, 2004 to December 31st, 2011 at Daegu Catholic University Medical Center. The average replication period was 27 months (12-64 months) and the average age at the time of the operation for removal was 41.5 years (21-75 years) for 55 males and 32 females. The quality of life for all patients was evaluated using Short Form 36 (SF-36) surveys before the operation for removal and after a minimum of one year. RESULTS: After an orthopedic operation for removal of internal fixative, physical health status showed statistically significant improvement (p=0.001); however mental health status did not (p=0.411). A satisfaction test for the subjective surgery written by patients indicated an improvement of subjective health status in 52.9% after the surgery for removal but with no difference in 29.9% compared to preoperation. CONCLUSION: In case of an operation for removal of internal fixative for patients with no related symptoms with internal fixatives used for treatment of fractures showing agglutination opinions, an improvement was observed in physical health status, not in mental health status. When surgery for removal of internal fixative is performed for patients without related symptoms, consideration that subjective satisfaction of patients shows an improvement only in 52.9% will be helpful.

Anti-HLA antibody related neonatal thrombocytopenia is an uncommon disorder caused by platelet antigen incompatibility between mother and fetus in Korea. Mothers who lack the specific platelet antigen produce the IgG against the platelet antigen which the fetus inherits from the father. These IgG antibodies are then transported across the placenta into the fetal circulation where they lead to the destruction of fetal platelets. We report a case of neonatal alloimmune thrombocytopenia related with anti-HLA antibody in second baby of dizygotic twin who had petechia on trunk and platelet count 43,000/mm. Initially, mother and twin showed the positives in antiplatelet antibodies. In microlym- phocytotoxic test at 6 months of age, anti-HLA antibodies was negative in twins but anti-HLA A2, A24 was positive in their mother. The patient was treated with intravenous immunoglobulin and clinically improved and her platelet count was norrnalized.

We experienced a case of Plasmodium falciparum gametocytemia successfully treated with primaquine in a twenty seven-years old woman. The patient had been admitted due to general malaise after diagosis and treatment of P. falciparum at Tanzania one month ago. On microscopic examination, P. falciparum gametocytemia was seen and treated with mefloquine for one week but gametocytemia was not disappeared. After primaquine treatment for two weeks, she was successfully treated.

PURPOSE: To study the early follow-up results of total hip arthroplasty using a 36 mm large femoral head MATERIALS AND METHODS: Sixteen of primary case and two of revision, who underwent total hip arthroplasty using a 36 mm Cobalt-Chrome femoral head with Longevity(R) (Zimmer , Warsaw, Indiana) as a polyethylene liner from August 2004 to April 2005, were evaluated. The average age was 53 years, and the mean follow-up period was 28.3 months(range, 24 to 32 months). The clinical outcome was analyzed, and the latest follow-up radiographs were assessed to determine the complications such as osteolysis, loosening, fracture, dislocation, etc. RESULTS: There were no complications such as infection and dislocation during the follow-up period. The Modified Harris Hip Scores was more than 'Good'in all cases with a mean score of 93. The Merle d' Aubigne and Postel scores was more than 'Good'in 78%. The radiographic examinations showed satisfactory fixation in all patients with uncemented and uncemented femoral components. There were no cases of osteolysis, loosening, dislocation, and fracture in the pelvis or proximal femur. CONCLUSION: No dislocation was encountered despite there being no limitation in the range of motion in the early post-operative period. Total hip arthroplasty using a large femoral head gave a higher satisfaction to the patients.

BACKGROUND: Opioids are known to increase the incidence of postoperative nausea and vomiting (PONV). Remifentanil is an ultrashort-acting opioid with a potent analgesic effect and is useful for rapid emergence. This study compared the effect of remifentanil on the incidence and severity of PONV and postoperative pain with that of fentanyl in patients undergoing laparoscopic surgery, which is normally associated with a high incidence of PONV. METHODS: Forty-four adult female patients, who were scheduled for laparoscopic ovarian cyst enucleation, were randomly assigned to either the remifentanil or fentanyl group. Anesthesia was induced with propofol after injecting fentanyl 2 microgram/kg or remifentnail 1 microgram/kg and was maintained with sevoflurane. Remifentanil and fentanyl was infused continuously in the range of 0.2-0.5 microgram/kg/min and 0.03-0.05 microgram/kg/min, respectively. Ketorolac 0.5 mg/kg was injected 30 min before the end of surgery. The incidence and severity of PONV and pain were recorded upon arrival at the recovery room and 2, 6, 12 and 24 hours thereafter. RESULTS: The incidence and severity of PONV and pain were significantly higher in the remifentanil group upon arrival at the recovery room than in the fentanyl group. The incidence and severity of PONV and pain at the other measurement times were similar. CONCLUSIONS: Despite the ultrashort action duration of the remifentanil, the incidence and severity of PONV and postoperative pain immediately after awakening was higher in the remifentanil group undergoing laparoscopic ovarian cyst enucleation than in the fentanyl group. However, there were no significant differences after two hours in the recovery phase.

BACKGROUND: Accurate quantitative testing of HBV DNA is very important for choosing antiviral treatment targets and evaluating treatment response in chronic HBV patients. We evaluated the performance of LG AdvanSure HBV Real-Time QPCR kit (LG) utilizing real-time quantitative PCR. METHODS: The LG kit was conducted for 201 chronic hepatitis patients undergoing treatment at the Korea University Ansan hospital and 48 normal control volunteers. The precision, limit of detection, sensitivity, and specificity of LG Kit were evaluated. Correlation analysis was done with Abbott Real Time HBV kit (Abbott) and the Cobas Amplicor HBV Monitor kit (Cobas) and the concordances rate of the three methods were calculated. RESULTS: The LG assay showed linear range of detection from 10(2) to 10(6) and coefficient of variation (CV) was 1.10~0.52% at > or =1,000 IU/mL and 1.19% at 100 IU/mL. The coefficient of determination for precision analysis was 0.997. The limit of detection for detection of 95% of positive samples was 9.71 IU/mL (54.4 copies/mL). In 201 clinical samples, the log HBV DNA/ml showed good correlation between Roche vs Abott, Roche vs LG and Abott vs LG, respectively (n=105, 108, 133, r2=0.91, 0.89, 0.94, P<0.0001). The overall concordance rate of three methods were 79.1% (159/201), 82.1% (165/201), and 85.1% (171/201), respectively, showing no stastically significant difference (P>0.05). CONCLUSION: LG AdvanSure HBV Real-Time QPCR kit showed outstanding precision, linearity, limit of detection, good correlation with previous methods, and is a valuable tool in treatment monitoring of chronic HBV infections.
