Renal tuberculosis commonly involves the urinary tract and results in multifocal fibrosis and stricture. Rarely, it presents as a renal mass with or without urinary tract abnormality. The radiologic features of this rare pseudotumor have not been sufficiently described in the previous literature, and we now report a case of tuberculosis presenting as an isolated renal mass and multiple hepatic nodules without evidence of associated urinary tract abnormality. The condition mimicked malignant neoplastic disease and occurred in a patient who had undergone chemotherapy for leukemia.

A 5-year-old, 28 kg castrated male Border Collie was referred for surgical intervention following complications from a prior total hip replacement. A physical examination revealed reduced weight-bearing and metallic crepitus on the affected limb. A radiographic assessment confirmed a fractured femoral stem. Extended trochanteric osteotomy (ETO) was performed to extract the well-fixed stem, followed by the removal of the acetabular cup. ETO stabilization was achieved with cerclage wires and a locking plate. Six months postoperatively, the radiographs indicated successful bone healing, and the dog exhibited improved limb function. The ETO technique can provide enhanced surgical access to extract well-fixed implants.

Detailed information on additional drug resistance patterns of multidrug-resistant tuberculosis (MDR-TB) is essential to build an effective treatment regimen; however, such data are scarce in Korea. We retrospectively analyzed the results of phenotypic drug susceptibility testing (DST) of culture confirmed-TB patients from January 2010 to December 2014 in 7 university hospitals in Korea. MDR-TB was identified among 6.8% (n = 378) of 5,599 isolates. A total of 57.1% (n = 216) of the MDR-TB patients had never been treated for TB. Strains from MDR-TB patients showed additional resistance to pyrazinamide (PZA) (35.7%), any second-line injectable drug (19.3%), and any fluoroquinolone (26.2%). Extensively drug resistant TB comprised 12.4% (n = 47) of the MDR-TB patients. Of 378 MDR-TB patients, 50.3% (n = 190) were eligible for the shorter MDR-TB regimen, and 50.0% (n = 189) were fully susceptible to the 5 drugs comprising the standard conventional regimen (PZA, kanamycin, ofloxoacin, prothionamide, and cycloserine). In conclusion, the proportion of new patients and the levels of additional drug resistance were high in MDR-TB patients. Considering the high levels of drug resistance, the shorter MDR-TB treatment regimen may not be feasible; instead, an individually tailored regimen based on the results of molecular and phenotypic DST may be more appropriate in MDR-TB patients in Korea.

BACKGROUND: Neuroendocrine tumors of the pancreas are classified according to the endocrine function as insulinomas gastrinomas somatostatinomas, or nonfunctioning tumors. However, the morphologic features are not different from each other. Therefore, we tried to compare correlations among the morphologic features, endocrine function, and the immunohistochemical reaction with specific monoclonal antibodies to the tumors. METHOD: We reviewed the medical records of seven patients with pancreatic neuroendocrine tumors retrospectively, and analysed the clinical manifestations, the methods of diagnosis, the pathological characteristics and the results of surgery. Additionally, we compared the correlation between the clinical manifestations and the expression of immunohistochemical staining by using six different kinds of monoclonal antibodies to each tumor. RESULTS: The seven pancreatic neuroendocrine tumor patients were treated by surgical excision. Four patients had benign insulinomas, two had nonfunctioning malignant tumor and one patient had a benign nonfunctioning tumor associated with stomach cancer. The pattern of immunohistochemical stain of each tumor was not correlate with the clinical manifestations. CONCLUSION: The morphologic study with H & E stain, even with immunohistochemical staining of pancreatic neuroendocrine tumor, cannot support differentiation of the functional diagnoses, such as insulinoma, gastrinoma, somatostatinoma, nonfunctional tumors and so forth.

Calving records of Holstein dairy cows from 2005 to 2010 comprising Goyang and Paju cities herd with 2,362 calving events representing 240 twin births were used to evaluate the effect of abomasal displacement and retained placenta after single or twin births on fertility. In retained placenta cows, the period of twin pregnancy (mean 270.5 days) was shorter than that of single pregnancy (mean 274.8 days), however first artificial insemination period (twin: mean 107.4 days, single: mean 92.0 days), non-pregnant period (twin: 154.8 days, single: 132.2 days), and number of insemination (twin: mean 2.00 times, single: mean 1.87 times) of twin pregnancy were increased as compared with single pregnancy. In abomasal displacement cows, first artificial insemination period (twin: mean 122.9 days, single: mean 106.0 days), non-pregnant period (twin: 172.4 days, single: 152.0 days), and number of insemination (twin: mean 2.16 times, single: mean 1.89 times) of twin pregnancy were increased as compared with single pregnancy. The prevalence of complication such as retained placenta, abomasal displacement with single or twin births increased first artificial insemination period, non-pregnant period, and number of insemination period.

PURPOSE: Metacarpal fractures are common hand injury that may require operative intervention to ensure adequate reduction and stabilization. Traditionally, titanium miniplate was used for rigid fixation of bone fractures. However, the use of permanent plate lends itself to multiple complications such as infection, exposure of the hardware, tendon adhesions, tendon rupture, prolonged pain, bony atrophy and osteoporosis (stress shielding), metal sensitization, and palpation under the skin. This study evaluated the usefulness and stability of biodegradable plates and screws for treatment of metacarpal bone fractures. METHODS: There was 17 patients who had surgery for metacarpal bone fracture from April 2007 to June 2010. All patients had open reduction and internal fixation. We used absorbable plates and screws (Inion CPS(R)) for internal fixation. Postoperative results were assessed with x-ray. Stability of plates and screws, healing process and its complications were observed by clinical and radiographic assessment. RESULTS: All patients were successfully reduced of bone fracture, and fixations with absorbable plates and screws were stable. The mean follow up period was 7.1 months. 2 patients complained postoperative pain, but they were relieved with analgesics. All patients experienced transient stiffness, but they were relieved with active assistive range of motion after removal of splint. No patients suffered complications which could be occurred by using metallic plate. CONCLUSION: There was no critical complications such as re-fracture or nonunion among patients. No patients suffered side effects related with metallic implants. Biodegradable implants can offer clinically stable and attractive alternative to metallic implants to stabilize metacarpal bone fractures in the hand.
