A 36-year old Korean woman consulted a clinic for a regular gynecological examination, and a mass was noticed in her pelvis. She was referred to the Asan Medical Center, Seoul where transvaginal ultrasonography confirmed a pelvic mass exceeding 10 cm in diameter. She received total abdominal hysterectomy and bilateral salpingoophorectomy, and a borderline serous neoplasm with micropapillary features involving the left ovary and right ovarian serosa was histopathologically confirmed. In addition, a section of a nematode with numerous eggs was found in the parenchyma of the left ovary. The worm had degenerated but the eggs were well-preserved and were identified as those of Enterobius vermicularis. She is an incidentally recognized case of ovarian enterobiasis.

PURPOSE: This study is to report clinical and radiological results of high-flexion total knee arthroplasty (TKA) using NexGen LPS-flex system at a minimum 5-year follow-up, and to analyze the implant survivorship based on the results. MATERIALS AND METHODS: A total of 80 patients (118 knees) who underwent patellar preserving TKA using NexGen LPS-flex implant between February 2007 and February 2008 and could be followed for minimum 5 years were reviewed. The range of motion (ROM), hip-knee-ankle angle, Knee Society Knee score (KSKS), and Knee Society Function score (KSFS) were assessed preoperatively and at the last follow-up and analyzed. Implant position of the femoral and tibial components on the immediate postoperative and last follow-up X-rays were compared. RESULTS: The mean ROM was 110.2degrees+/-14.5degrees (range, 60degrees to 140degrees) preoperatively and 132.4degrees+/-5.2degrees (range, 90degrees to 145degrees) at the last follow-up. KSKS was 36.9degrees+/-6.4degrees preoperatively and 94.2degrees+/-3.2degrees at the last follow-up. KSFS was 30.5degrees+/-5.7degrees preoperatively and 93.7degrees+/-4.1degrees at the last follow-up. There was no statistically significant change in the implant position measured as alpha, beta, gamma, and delta angles at the last follow-up compared to the immediate postoperative values. Radiolucent lines were observed in 13 knees (11%) on the last follow-up X-rays. Revision TKA was performed due to aseptic implant loosening in 1 knee (0.84%), and the survival rate at the 5th postoperative year was 99.2%. CONCLUSIONS: The clinical and radiological outcomes of high-flexion TKA using NexGen LPS-Flex implant design were satisfactory with 99.2% implant survival rate after 5 years of protected activities of daily living.

Endomyocardial biopsy (EMB) is a valuable diagnostic procedure for the surveillance of cardiac allograft rejection. Interpretation of individual cases is still problematic due to variations of findings for grading of rejection and other associated lesions. We reevaluated an experience on endomyocardial biopsies to develop better diagnostic criteria for rejection and other complications. Immunohistochemical studies against cytokines were performed to assess the usefulness of the method for the diagnosis or researches. A total of 249 EMBs taken from 33 cardiac allograft recipients were reviewed. There were 25 males and 8 females. Dilated cardiomyopathy was present (24 cases) and valvular heart disease (4 cases), restrictive cardiomyopathy (3 cases) were also common conditions. We applied the grading system of the International Society for Heart Transplantation (ISHT) for the assessment of acute cellular rejection. Grades of 0, 1A, 1B, 2, 3A and 3B were 39.0%, 28.1%, 11.2%, 11.5%, 12.4% and 1.6% respectively, but 3.2% were inadequate. Thirty five episodes of grade 3A or 3B were present in 17 patients. The response to therapy was assessed using a next follow up biopsy, which revealed resolving or resolved rejection in 85% of patients. The intensity of immunohistochemical stains for IL-6 and TNF-alpha was increased in proportion to the histologic grade but Quilty lesion and cardiomyopathy also showed a positive reaction. The other pathologic findings were ischemic change, previous biopsy site, interstitial edema and fibrosis, and Quilty lesion. These findings showed usefulness of endomyocardial biopsy not only for the evaluation of cardiac allograft rejection but also for the diagnosis of associated cardiac lesions. Immunohistochemical study of the cytokines was related to the degree of inflammation rather than degree of rejection.

PURPOSE: We investigated the operative outcome after bypass surgery in patients selected using viability criteria on F-18 FDG PET. MATERALS AND METHODS: Rest-24hr delay redistribution imaging of Tl-201 SPECT and F-18 FDG PET were performed in 11 patients. Seven of these 11 patients (6 men, 1 woman) were evaluated to have viable myocardium by F-18 FDG PET. Changes in symptoms and left ventricular ejection fraction (LVEF) after operation were evaluated. RESULTS: In seven of 11 patients, a significant amount of viable myocardium was found on F-18 FDG PET and Tl-201 SPECT. Severity of both chest pain and dyspnea improved markedly in all patients. Mean LVEF improved from 22% to 32%. CONCLUSION: F-18 FDG PET could be used to select the patients who will benefit from coronary artery bypass surgery.

The occurrence of a trigeminal neuropathy associated with connective tissue disease is rare. Trigeminal neuropathy in connective tissue disease is predominantly sensory and it is characterized by numbness, hypesthesia, slurred speech, and touch pain. Although the pathogenesis of trigeminal neuropathy associated with connective tissue disease remains obscure, the main pathologic findings are vasculitis and neuritis. A case of trigeminal neuropathy associated with mixed connective tissue disease is described, and the incidence, symptoms, pathophysiology, treatment of the disease is discussed.

Neurocutaneous melanosis is a rare congenital syndrome characterized by the presence of large or multiple congenital melanocytic nevi and benign pigment cell tumors of the leptomeninges. Neurocutaneous melanosis is thought to represent an error in the morphogenesis of embryonal neuroectoderm. We experienced a neonate who presented with giant, dark colored pigmented nevi covering chest, abdomen, neck and arms, with satellite lesions. Magnetic resonance image showed a nodular hyperintense lesion in the amygdala of the right temporal lobe, and T1-weighted images showed hyperintensities in the adjacent leptomeninges. We report a rare case of neurocutaneous melanosis with a brief review of related literature.

Drug eruption is a cutaneous reaction caused by various drugs, which include antibiotics, antipyretics, anti-inflammatory analgesics, antidepressants, antituberculosis drugs, etc. Drug eruptions caused by antituberculosis drugs are relatively uncommon and there have been no previous reports in Korea which caused simultaneously by isoniazid and rifampin. A 57-year-old female patient, who was treated with antituberculosis drugs, was seen with generalized erythematous maculopapular eruption. We performed patch test and prick test with the antituberculosis drugs and could confirm a drug eruption caused by isoniazid and rifampin. And we performed desensitization to isoniazid for an optimal antituberculosis regimen and completed the treatment with isoniazid, successfully.

Hepatoblastoma is the most common primary malignant hepatic tumor in infancy and childhood. But congenital hepatoblastomas are extremely rare and show distinctive, but important features when compared with tumors diagnosed in children beyond the neonatal age. They have different clinical presentations, higher incidence of pure fetal histology, significant risk for systemic metastasis, and worse outcome. The treatment of congenital hepatoblastoma should be the same as in older children, i.e., primary chemotherapy with delayed resection. We report a case of congenital hepatoblastoma in a 29-day-old boy who was known to have a well-defined ovoid hypoechoic mass at liver demonstrated by fetal sonography.
