Tumoral calcinosis is an ectopic calcification syndrome characterized by an irregular soft tissue mass. It has been reported mainly in large joints such as the hip, shoulder, knee, and elbow, but rarely in the hands. When it occurs on the dorsal side of the wrist, there are no specific symptoms except for localized tenderness. Therefore, it is difficult to differentiate the calcification from other common hand tumors, especially ganglions. We report a case of tumoral calcinosis that occurred on the dorsal side of the wrist with magnetic resonance imaging findings.

Background: Surgical treatment consisting of decompression and fusion is generally known to produce good clinical results for lumbar spinal stenosis with degenerative spondylolisthesis. However, the clinical outcome of decompression alone, without fusion, remains unclear, and long-term follow-up results are scarce. This study aimed to retrospectively analyze the 5-year clinical results of decompression only in patients with lumbar spinal stenosis and degenerative spondylolisthesis. Methods: Among the patients diagnosed as having lumbar spinal stenosis with degenerative spondylolisthesis, 36 patients who underwent decompression without fusion and were followed up for minimum 5 years were included in this study. The average follow-up period was 7.2 years, and the mean age of patients was 63.2 years. Visual analog scale (VAS) score and Oswestry disability index (ODI) were investigated pre- and postoperatively, and also radiologic displacement and instability were measured. In addition, patients who needed fusion or redecompression at the decompression site postoperatively were also investigated. Results: VAS score and ODI improved from an average of 7.8 points and 57 points preoperatively, respectively, to 1.4 points and 19 points at 5 years postoperatively, respectively. The degree of radiologic displacement increased from an average of 5.1 mm preoperatively to 6.4 mm at the final follow-up. Radiological instability was detected in five patients. Two patients (9.5%) required fusion. Conclusions The long-term follow-up results revealed that satisfactory clinical outcomes were obtained with decompression alone, without fusion, for patients with lumbar spinal stenosis and degenerative spondylolisthesis.

Purpose: To evaluate clinical-functional and radiologic outcomes of elderly patients with an unstable intertrochanteric femur fracture treated with a wedge wing in the lag screw. Materials and Methods: Forty-eight patients treated with the Dyna Locking Trochanteric nail (DLT nail) to resolve an unstable intertrochanteric femur fracture were reviewed retrospectively. Based on AO/OTA classification, Fracture 31-A2 (34 cases) and 31-A3 (14 cases) were included in the analysis. We measured the femoral neck-shaft angle, tip-apex distance (TAD), Cleveland index, sliding distance of the lag screw, and time to the fracture union. The Harris Hip Score and Paker and Palmer’s mobility score for clinical evaluation were used. Results: The mean follow-up period was 21.4 months (range, 12-34 months). The postoperative state of reduction was good in 28 cases and acceptable in 20 cases. The mean TAD was 20.5 mm. The position of the lag screw was center-center in 30 cases and center-inferior in 18 cases. The mean sliding distance of the lag screw was 3.4 mm at the last follow-up. The mean union time was 4.5 months. Two cases had complications which included a cut-out (1 case) and non-union (1 case). The mean Harris Hip Score was 86.5±8.3 (range, 76-90).Walking ability in 34 of the cases (70.8%) at last follow-up was similar to that prior to fracture. Conclusion Functional and radiological outcomes are satisfactory using the DLT nail in the treatment of elderly patients with unstable intertrochanteric fractures; however, wedge wing in the lag screw does not prevent implant-related complications.

BACKGROUND: Prevalence of bee venom allergy in Korea is unknown, OBJECTIVE: We performed a cross-sectional study to evaluate the prevalence of bee venom allergy and importance of risk factors, such as age, sex, and atopy, in the development of the allergic reaction in children and adults living in rural area of Cheju Island. Swbject and METHOD: The prevalence was investigated in subjects with 1,054 children and 370 adults (701 male, 723 female), aged 7-87 years, living in rural area of Cheju Island. A history particularly focused on the systemic reactions after the bee stings was taken in all subjects. Skin prick test,s to common inhalant allergens, including house dust mites, fungi, tree, grass, mugwort and ragweed pollen, cockroach, animal epithelium, Japanese cedar pollen, and citrus red mite were performed. RESULT: The prevalence of bee venom allergy was 5.8% (mild systemic reactions 5.0%, severe systemic reactions 0.8% ). The prevalence was higher in adults than in children (10.2% vs. 5.0%, g = 12.0, p<0.01). Among the children, the prevalerlce wB.S Signifcantly higher ill male than in female (8.6% vs. 1.3%, x=28.7, p<0.01), but no significant diffecence was noted between male and female in adults (10.0% vs. 10.3%, p>0.05). The prevalence of bee venom allergy was not significantly different between subjects with positive skin reaction and those with negative skin reaction to inhalant allergens (6.4% vs. 5.4% ), Conclasion'. The prevlence of bee venom allergy in inhabitants of rural area of Cheju Island is 5.8% (mild systemic,' 5.0%, severe systemic reaction. 0.8%), and bee venom allergy was more common in adults than in children, and in male children than in female children.

Neurofibromatosis type 1 (NF1) is a genetic disease characterized by neoplastic and non-neoplastic disorders involving tissues of neuroectodermal and mesenchymal origin. NF1 is caused by mutations in the NF1 gene, which is found on chromosome 17q11.2. Patients with NF1 are at increased risk of developing soft tissue sarcomas that arise within the stromal compartment of the gastrointestinal tract, termed gastrointestinal stromal tumors (GISTs). GISTs associated with neurofibromatosis differ from sporadic GISTs, particularly with respect to their lower response rate to imatinib. We recently experienced a case involving a 45-year-old man with NF1 who was admitted to the hospital with epigastric pain and vomiting. Abdominal computed tomography revealed a duodenal GIST with pancreatic invasion. He had a base substitution mutation involving replacement of 2041 cytosine with thymine. He was treated successfully with a surgical operation and adjuvant imatinib therapy.

PURPOSE: We conducted a multi-center, phase II trial to evaluate the efficacy and safety of using Padexol (a paclitaxel formulation) combined with cisplatin for the patients suffering with advanced gastric adenocarcinoma. MATERIALS AND METHODS: 39 patients (median age: 60 years; males: 90%) who were diagnosed with advanced gastric cancer were enrolled from 5 hospitals. Padexol 175 mg/m2 was administered as a 3-hr infusion, and this was followed by cisplatin 75 mg/m2 as an intravenous infusion on day 1, once every 3 weeks. RESULTS: Out of these 39 patients, 34 patients were assessable for treatment efficacy and 39 patients were assessable for the toxicity. Objective responses occurred in 13 patients (33%); 1 patient (3%) had a complete response and 12 patients (31%) had partial responses. 6 patients (15%) achieved a stable disease state. The median duration of response was 7.1 months, and the median time to progression and the overall survival were 4.8 months and 6.7 months, respectively. The major treatment-related adverse events were hematologic toxicity, including WHO grade 3 or 4 neutropenia in 13 patients (33%). However, febrile neutropenia occurred in only 1 patient and the non-hematologic toxicity was usually mild. CONCLUSION: The combination of Padexol and cisplatin was found to be active and it seems to be a relatively well-tolerated regimen for the treatment of advanced gastric cancer.

BACKGROUND: Stress-induced cardiomyopathy (SCM) is characterized by apical ballooning on echocardiography, but some of SCM patients show non-apical involvement and their characteristics are not well defined. METHODS: We investigated 56 patients that were diagnosed as SCM and divided them into 2 groups: apical ballooning syndrome (ABS, n = 49, 87.5%) and non-apical ballooning syndrome (N-ABS, n = 7, 12.5%) groups. Patients with N-ABS were significantly younger than those of the ABS group (52 +/- 11 vs. 73 +/- 10 years, p < 0.001). RESULTS: Types of preceding stressors and clinical presentation including chest pain, pulmonary edema, cardiogenic shock and in-hospital mortality were comparable between the two groups. In the N-ABS group, wall motion score index was significantly lower than in the ABS group (1.61 +/- 0.35 vs. 1.93 +/- 0.31, p = 0.016). On electrocardiogram (ECG), T-wave inversion (57.1% vs. 95.8%, p < 0.001) were less frequent in the N-ABS than in the ABS group. Furthermore, maximum QT and corrected QT (QTc) intervals in the N-ABS patients were significantly shorter than the ABS patients (QT, 419.9 +/- 66.1 vs. 487.3 +/- 79.6 ms, p = 0.038; QTc, 479.0 +/- 61.9 vs. 568.0 +/- 50.5 ms, p < 0.001). CONCLUSION: Patients with the N-ABS showed not only atypical echocardiographic findings, but also atypical clinical and ECG manifestations. Integrated consideration is needed to reach a diagnosis of the non-apical subtype of SCM.

Umbilical cord blood is an attractive source of hematopoietic stem cells in allogeneic hematopoietic stem cell transplantation. Umbilical cord blood transplantation has merits of rapid availability and low risk of severe acute graft versus host disease. Umbilical cord blood should be an important source of stem cell transplantation for patients who have no suitable human leukocyte antigen-matched bone marrow, or peripheral stem cell donor. Transplantation of umbilical cord blood is limited by insufficient cell doses. This had led to the alternative concept of attempting to increase the number of cell doses using two cord blood units from different donor. We report a case of double-unit cord blood transplantation for 55-year-old male with primary refractory acute myeloid leukemia.
