Biliary cystadenoma is a rare biliary ductal neoplasm that usually arises in the liver and less frequently in the extrahepatic bile ducts. Clinical manifestations are non-specific; hence preoperative diagnosis depends heavily on imaging. Computed tomography, ultrasonography, angiography and cholangiogram are useful diagnostic procedures in biliary cystic tumor, but definite diagnosis depends on histologic diagnosis. Surgical resection often yields excellent results. Surgical procedures used to treat cystadenomas include: aspiration, drainage, marsupialization, and excision. If there is no evidence of metastasis, complete resection of these tumors is necessary for a complete cure. We experienced an 80-year-old man who complained of jaundice and RUQ pain. He was diagnosed as biliary mucinous cystadenoma, We confirmed our diagnosis by cholangioscopic biopsy, and performed endoscopic sphincterotomy(EST). So, we report this case and have reviewed the relevant literature as a part of our report for the subject case.

Vigabatrin-induced myoclonus is rarely described in adult with partial epilepsy, We report vigavatrin-induced mulrifocal action myoclonus in a 34 year-old female with symptomatic partial epilepsy. Hwe seizures were resistant to catbamazepine. Vigabatrin was started as add-on therapy and multifocal action myoclonus was developed one month later. Myoclonus disappeared after withdrawal of vigabatrin and reappeared with re-use of it. Based on clinical features of myoclonus, her myoclonus may be non-epileptic in nature.

Diabetic thoracic radiculopathy is not uncommon, but unfamiliar disease entity complicated by long standing diabetes mellitus. It is characterized by typical distressing sensory disturbances and lancinating pains on abdomen and flanks along the thoracic dermatomes in long-standing diabetic patients, which subsides spontaneously. Diagnosis is made by clinical findings and electrodiagnostic technics and other conditions that can affect thoracic spinal root level should be rulled out. With reviewing some literatures, we present two cases which showed the characteristic features of this disorder.

BACKGROUND: We evaluated the clinical and radiologic results of impacted femoral neck fractures treated with multiple pinning and determined the influence of the progression of impaction at the fracture site on clinical outcome. METHODS: There were 34 patients with a mean age of 65.5 years. The mean follow-up period was 3.4 years. Progression of fracture site impaction was measured using an articulo-trochanteric distance index and the percentage decrease in the articulo-trochanteric distance index between follow-up intervals. The failure of treatment was clarified as non-union and avascular necrosis. Other characteristics of the patients, including mean waiting time for surgery, preoperative Singh index score, and body mass index, were also measured to evaluate the influence on the clinical outcome of surgery. RESULTS: There were 6 fractures which were not treated successfully (3 non-union, 8.8% and 3 avascular necrosis, 8.8%). The mean percentage decrease of the articulo-trochanteric distance index within the first 6 weeks after surgery was 4.5% in the successful group and 25.1% in the failure group (p < 0.001). There was also a significant mean percentage decrease in the articulo-trochanteric distance index between 6 weeks and 3 months (p < 0.001). CONCLUSIONS: Primary stabilization with Knowles pins for impacted femoral neck fractures had a reasonable clinical outcome with low morbidity. Despite a significant difference of a mean percentage decrease in the articulo-trochanteric distance index between the successful group and the failure group, we could not verify it as a risk factor for failure of treatment because the odds ratio was not statistically significant.

We present a case of Aspergillus septic hip arthritis in an immunocompetent patient with undiagnosed recurrent pulmonary aspergillosis who underwent arthroscopic surgery. Biopsy specimens of synovium revealed fungal hyphae, confirming Aspergillus infection. Aspergillus septic hip arthritis can occur in immunocompetent patients, and arthroscopy can be a noninvasive surgical option in these cases.

We evaluated the clinical course of subchondral insufficiency fracture of the femoral head (SIFFH) and its characteristic findings with special regard to joint space narrowing (JSN). Thirty-one cases of SIFFH of mean age 68.9 yr initially underwent limited weight-bearing conservative treatment. During the follow-up period, the patients with intractable pain underwent total hip arthroplasty (THA). For radiographic evaluation, lateral center-edge angle, JSN and femoral head collapse (FHC) were documented, and the extent of FHC was classified as mild (<2 mm), moderate (2-4 mm), and severe (>4 mm). The progression or new development of FHC more than 2 mm was evaluated on sequential plain radiographs. The relationship between radiographic parameters and clinical outcomes were evaluated. THAs were performed in 15 cases (48.4%). There was no significant correlation between clinical outcomes and the extent of initial FHC. However, a significantly larger proportion of patients that underwent THA showed JSN and FHC progression compared to the symptom improvement group. The risk factor significantly associated with failed conservative treatment was JSN (P=0.038; OR, 11.8; 95% CI, 1.15-122.26). Clinical results of conservative treatment for SIFFH in elderly patients are relatively poor. The patients with JSN are at higher risk of failed conservative treatment.

Background: Outcomes of traditional treatment for osteonecrosis of the femoral head (ONFH) are not always satisfactory. Hence, cell-supplementation therapy has been attempted to facilitate necrotic-tissue regeneration. Adipose-derived mesenchymal stem cell (ADMSC) transplantation is potentially advantageous over bone marrow-derived MSC implantation, but its outcomes for ONFH remain unclear. The aim of this study was to determine 2-year radiological and clinical outcomes of culture-expanded autologous ADMSC implantation for ONFH. Methods: Eighteen hips with necrotic lesions involving ≥ 30% of the femoral head were included. ADMSCs were harvested by liposuction and culture expanded for 3 passages over 3 weeks. With a 6-mm single drilling, ADMSCs were implanted into the necrotic zone. All patients underwent magnetic resonance imaging (MRI), single-photon emission computed tomography/computed tomography (SPECT/CT) at screening and 6 months, 12 months, and 24 months postoperatively. The primary outcome was the change in the size of necrotic area on MRI. Secondary outcomes were changes in clinical scores and radioisotope uptake on SPECT/CT. Conversion total hip arthroplasty (THA) was defined as the endpoint. Results: Preoperatively, the necrotic lesion extent was 63.0% (38.4%–96.7%) of the femoral head. The mean Harris hip score was 89.2, the University of California at Los Angeles (UCLA) score was 5.6, and Western Ontario and McMaster Universities Arthritis index (WOMAC) was 79.4. Three patients underwent THA and 1 patient died in an accident. Finally, 11 patients (14 hips) were available for ≥ 2-year follow-up. At the last follow-up, no surgery-related complications occurred, and 14 of 17 hips (82%) were able to perform daily activities without THA requirement. There was no significant decrease in lesion size between any 2 intervals on MRI.However, widening of high signal intensity bands on T2-weighted images inside the necrotic lesion was observed in 9 of 14 hips (64%); 11 of 14 hips (79%) showed increased vascularity on SPECT/CT at 2 years postoperatively. No significant differences were observed between preoperative and 24-month mean Harris hip score (89.2 vs. 88.6), WOMAC (79.4 vs. 75.7), and UCLA score (5.6 vs. 6.2). Conclusions Our outcomes suggest that culture-expanded ADMSC implantation is a viable option for ONFH treatment without adverse events.

Gastric bezoar has been known to occur occasionally in the gastrointestinal tract, as a result of foreign material accumulating in the stomach. Most case have been managed by surgical methods. Currently, the endoscopic mathod is after used for the gastrointestinal disease, and therefore we treated two cases of huge bezoars using the endoscopic polypectomy snare and lithotriptor. Subsequently, we are reporting these cases and have incorporated relevant literature which was reviewed for our report for the subject case.

DNA methylation is the most common and well-characterized epigenetic change in human cancer. Recently, the association between GATA-binding protein 5 (GATA5) methylation and carcinogenesis of various types of tumors was investigated. The aim of the present study was to evaluate the effect of GATA5 methylation status on clinicopathological features and prognosis in primary non-muscle invasive bladder cancer (NMIBC) patients with a long-term followup period. The GATA5 methylation status was determined for 171 human bladder specimens (eight normal controls [NCs] and 163 primary NMIBC patients) using quantitative pyrosequencing analysis. The primary NMIBC tissues were obtained from patients who underwent transurethral resection (TUR) for histologically diagnosed transitional cell carcinomas between 1995 and 2012 at Chungbuk National University Hospital. GATA5 methylation was significantly higher in NMIBC patients than in NCs and was significantly associated with higher grade and more advanced stage of cancer. Kaplan-Meier estimates showed significant differences in tumor recurrence and progression according to GATA5 methylation status (each p<0.05). Our results show that increased methylation of GATA5 was significantly associated with not only aggressive characteristics but also poor prognosis in primary NMIBC patients. Alteration of GATA5 methylation might be used as a biomarker for prognosis of NMIBC patients. However, prospective and functional investigations are necessary to clarify the role of GATA5 methylation in future clinical management of patients with NMIBC.
