We report two cases of cutaneous Mycobacterium(M.) marinum infections in a 43-year-old man and a 31-year-old woman who had multiple subcutaneous nodules on the left upper extremity and an erythematous ulcer on the right elbow, respectively. Skin biopsy specimens revealed chronic granulamatous inflammation and AFB positive bacilli in the dermis. The culture from tissue specimens on Lowenstein-Jensen media at 30'C for 10 days, yielded cream-colored colonies, which became yellow when exposed to light. The organism was identified as M. marinum by selected biochemical reactions. The patients were treated with surgical excision followed by administration of minocycline and administration of minocycline, respectively.

Purpose: The aim of this study was to report seven cases of metallic radial head prosthesis and present the limit of use in Korea. Materials and Methods: Metallic radial head arthroplasty was performed on 7 patients between April 2006 and December 2006, who had complex elbow injury including comminuted radial head fracture. Indication, operative findings and outcome were assessed. Availability and payment of implant were investigated. Results: All of the patients had more than one associated injury including coronoid fracture, olecranoan fracture, and ligament ruptures. According to Mason classification, there were three type III and four type IV fractures. All radial head fractures were too comminuted to reconstruct. There were two excellent results, four good, and one poor, as graded by Mayo score. There were no patient with instability and implant related complications. Insufficient supply of implant did not enable to do scheduled surgery in 2 cases. Current medical insurance did not cover charge for radial prosthesis, five patients could not help paying for that by themselves. Conclusion: Metallic radial head implants are useful when the radial head cannot be repaired reliably. Preoperative preparing and coverage by medical insurance based on appropriate indication are helpful for decision for a treatment option.

BACKGROUND: Postoperative nausea and vomiting (PONV) is a common problem after general anesthesia. Compared with inhalational anesthetics, propofol has an antiemetic effect. We investigated the incidence of PONV after propofol and sevoflurane anesthesia for strabismus surgery in pediatric patients, and evaluated the effectiveness of ondansetron prophylaxis after sevoflurane anesthesia. METHODS: A healthy pediatric patients (n = 150) were divided into three groups. Group P (n = 50) received intravenous anesthesia with propofol; Group S (n = 50), inhalational anesthesia with sevoflurane; and Group S-O (n = 50), inhalational anesthesia with sevoflurane and 0.06 mg/kg (up to 4 mg) of ondansetron. The occurrence and intensity of PONV were recorded. RESULTS: The incidence of PONV after sevoflurane-ondansetron anesthesia did not differ from that after propofol anesthesia, but was significantly attenuated. The recurrence of PONV after sevoflurane-ondansetron was lower than after propofol and sevoflurane anesthesia. CONCLUSIONS: Sevoflurane anesthesia with ondansetron prophylaxis may be a good alternative to propofol in terms of avoiding PONV.

BACKGROUND: Anatomic footprint restoration of anterior cruciate ligament (ACL) is recommended during reconstruction surgery. The purpose of this study was to compare and analyze the femoral and tibial tunnel positions of transtibial single bundle (SB) and transportal double bundle (DB) ACL reconstruction using three-dimensional computed tomography (3D-CT). METHODS: In this study, 26 patients who underwent transtibial SB ACL reconstruction and 27 patients with transportal DB ACL reconstruction using hamstring autograft. 3D-CTs were taken within 1 week after the operation. The obtained digital images were then imported into the commercial package Geomagic Studio v10.0. The femoral tunnel positions were evaluated using the quadrant method. The mean, standard deviation, standard error, minimum, maximum, and 95% confidence interval values were determined for each measurement. RESULTS: The femoral tunnel for the SB technique was located 35.07% +/- 5.33% in depth and 16.62% +/- 4.99% in height. The anteromedial (AM) and posterolateral (PL) tunnel of DB technique was located 30.48% +/- 5.02% in depth, 17.12% +/- 5.84% in height and 34.76% +/- 5.87% in depth, 45.55% +/- 6.88% in height, respectively. The tibial tunnel with the SB technique was located 45.43% +/- 4.81% from the anterior margin and 47.62% +/- 2.51% from the medial tibial articular margin. The AM and PL tunnel of the DB technique was located 33.76% +/- 7.83% from the anterior margin, 45.56% +/- 2.71% from the medial tibial articular margin and 53.19% +/- 3.74% from the anterior margin, 46.00% +/- 2.48% from the medial tibial articular margin, respectively. The tibial tunnel position with the transtibial SB technique was located between the AM and PL tunnel positions formed with the transportal DB technique. CONCLUSIONS: Using the 3D-CT measuring method, the location of the tibia tunnel was between the AM and PL footprints, but the center of the femoral tunnel was at more shallow position from the AM bundle footprint when ACL reconstruction was performed by the transtibial SB technique.

PURPOSE: The purpose of this study was to evaluate the anatomical similarity of three-dimensional (3D) morphometric parameters between right and left knees. MATERIALS AND METHODS: Ten fresh-frozen paired cadaveric knees were tested. Following dissection, footprint areas of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) were measured. Surface scanning was performed using a 3D scanner. Scanned data were reproduced and morphometric parameters were measured on specialized software. After making mirror models, we compared footprint center positions of the ACL and PCL of both sides and calculated the average deviation of 3D alignment between the right- and left-side models. RESULTS: No significant side-to-side differences were found in any morphometric parameters. Bony shapes displayed a side-to-side difference of < 1 mm. Distal femoral and proximal tibial volumes did not present side-to-side differences, either; the average 3D deviations of alignment between the right and left sides were 0.8±0.4/1.1±0.6 mm (distal femur/proximal tibia). Center-to-center distances between the right and left ACL footprints were 2.6/2.7 mm (femur/tibia) for the anteromedial bundle and 2.4/2.8 mm for the posterolateral bundle. They were 1.9/1.5 mm for the anterolateral bundle and 2.2/1.8 mm for the posteromedial bundle of the PCL. CONCLUSIONS: There was a remarkable 3D morphometric similarity between right and left knees. Our results might support the concept of obtaining morphologic reference data from the uninvolved contralateral knee.

Sleeve fractures of the patella are cartilaginous avulsion fractures from the lower pole of the patella. They occur mainly due to sports injuries in adolescents. They may be missed in diagnosis due to rare incidence and small bony fragment on simple radiographs. In this report, an unusual bilateral simultaneous sleeve fracture in a healthy child is described.

PURPOSE: This study examined the results of treatment according to the stage and size of a spontaneous osteonecrosis lesion of the knee (SONK) in the patients over 60 years of age. MATERIALS AND METHODS: Twenty-two knees from 19 patients over 60 years of age were treated for spontaneous osteonecrosis of the knee at our institution between January, 2000, and June, 2004. The mean follow time was 20.7 months. The condylar ratios, proportion of the lesion size to the condyle were measured. The size was obtained by multiplying the values from the anteroposterior and lateral radiographs. The stages were classified radiographically, and the treatment results were analyzed according to the size and stage. Conservative treatment was performed if the ratio and size were <40% and 5.0 cm2, respectively. Arthroplasty was performed if the ratio or size was >40% or 5.0 cm2. A paired T-test, Spearman correlation test and Wilcoxon test were used for the statistical evaluation. RESULTS: There was a higher prevalence in females (15 patients, 79%), and the mean age was 65 years (46-77 years). Bilateral involvement was observed in 3 patients. The lesions involved mainly the medial femoral condyle (21 cases, 95%). Seven cases (31%) had a condylar ratio <40% and 15 cases (69%) had a condylar ratio >40%. Conservative treatments were performed in 5 cases staged radiographically as I or II and there were no significant changes in the knee scores (p=0.931). Of the 17 cases staged III and IV radiographically, conservative treatment and arthroplasty were performed in 7 and 10 cases, respectively. Seven cases, in whom conservative treatments had been performed, showed a decreased in the knee scores compared with the increased knee scores in 10 patients treated with arthroplasty (p=0.943). CONCLUSION: An accurate diagnosis and measurement of the size and staging of spontaneous osteonecrosis of knee in patients over 60 years of age is important for proper treatment. Clinically, no further progression of symptoms is visible on grade I and II spontaneous osteonecrosis of the knee after conservative treatment. However, arthroplasty improves the clinical results in patients with radiological grade III and IV osteonecrosis compared with conservative treatment.

PURPOSE: Allergic rhinitis (AR) is one of the most common childhood diseases in Korea. In this study, we aimed to investigate the prevalence and allergens of childhood AR in Gwangju. METHODS: From April 2013 to September 2013 in Gwangju, skin prick test and questionnaire survey were performed targeting 2,330 children in total (350 kindergartners, 930 elementary school students, 589 middle school students, and 461 high school students). RESULTS: The overall prevalence of AR was 23.5% (female 21.3%, male 26.1%). According to age groups, prevalence of AR was 14.9% (female 10.7%, male 19.8%) in kindergartners, 24.5% (female 18.8%, male 29.4%) in elementary school students, 23.3% (female 18.1%, male 27.6%) in middle school students, 26.2% (female 27.7%, male 23.2%) in high school students. The most common allergen was Dermatophagoides pteronyssinus (79.7%), followed by Dermatophagoides farina (72.2%), birch (14.0%), alder (12.0%), Japanese hop (9.2%), Alternaria (8.9%), cat fur (7.2%), Japanese cedar (6.9%), ryegrass (6.6%), willow (6.0%), pine (5.4%), oak (4.9%), mugwort (4.3%), orchard grass (4.0%), sheep fescue (3.7%), fat hen (3.4%), ragweed (3.4%), and maple (3.4%). CONCLUSION: This research figures out the prevalence and the detailed allergens of AR in Gwangju children. We suggest that more vegetation data of Japanese cedar should be surveyed in recent future.
