Traumatic optic neuropathy is a complication resulting from facial trauma, with an incidence of 2% to 5%. The most widely accepted treatments include observation, high dose steroid, surgical decompression and combination therapy of steroid and surgical treatment. However, there has been no established mode of treatment and there are still debates about what the best treatment should be for the patients with optic canal fracture. We experienced two cases of traumatic optic neuropathies due to intracanalicular fracture of the optic canal after trauma. Surgical decompression was performed using an endoscope int-ranasally one day after injury as required for minimal invasive surgery. We report the results and progression of these two cases.

Ocular symptoms related to orbital fracture occur immediately after the fracture in most cases. However, authors experienced a delayed onset diplopia occurred 16 months after orbital floor fracture. A 19-year-old man, who had right orbital floor fracture 16 months ago, presented with diplopia of upward gaze. At the time of the fracture, no surgery was performed because the fracture was minimal and there were no particular symptoms. Physical examinations revealed a minor ocular motility restriction of upward gaze, but orbital floor showed no definite interval change on computed tomography. Severe adhesion between the orbital fat tissue and orbital floor was noted intraoperatively and the adhesion was dissected. After the operation, the patient showed remarkable improvement in diplopia and restriction of the ocular motility.

The hyalinizing trabecular adenoma (HTA) of the thyroid gland is a rare benign tumor, which is characterized by a trabecular growth pattern with hyaline stroma. This tumor is occasionally misdiagnosed as papillary carcinoma and medullary carcinoma. Distinguishing pathologic findings and immunochemical studies are needed to make a definite diagnosis. Recently, we experienced a case of HTA of the thyroid gland. A 54-year-old woman presented with both thyroid nodules (mainly the left thyroid). Fine needle aspiration cytology showed atypical follicular cells. We performed left hemithyroidectomy and finally diagnosed the specimen as HTA. We present this rare case with a brief review of the disease entity.

BACKGROUND: We aimed to confirm the long-term effect of patellar nonresurfacing (patellar decompression) in preventing anterior knee pain after total knee arthroplasty (TKA) and to investigate the possible complications. METHODS: Among patients who underwent primary TKA after being diagnosed as having advanced osteoarthritis (Kellgren-Lawrence grade 4) at our institution from January 2004 to December 2010, 121 patients who were followed up for more than 7 years were included in this study. Patients who underwent TKA with and without patellar decompression were classified as the study group and control group, respectively. A clinical knee rating score was used to compare the postoperative clinical outcomes between groups. To identify complications after patellar decompression, simple radiographs (weight-bearing anteroposterior and lateral views, patella in 30° and 45° axial views, and whole scanogram) were taken during follow-up. RESULTS: There were no complications such as patellar fracture, osteonecrosis, and subluxation. At 2 years after surgery, the prevalence of anterior knee pain was 12.7% and 18.0% in the study group and control group, respectively (p = 0.42), and the number of patients with patellofemoral osteoarthritis grade II or over was lower in the study group (p = 0.03). At 7 years after surgery, the prevalence of anterior knee pain was 18.3% and 24.0% in the study group and control group, respectively (p = 0.45), and there was no statistically significant intergroup difference in the number of patients with patellofemoral osteoarthritis grade II or over (p = 0.11). CONCLUSIONS Patellar nonresurfacing TKA reduces anterior knee pain in the early postoperative period. The procedure can be considered a relatively safe option with fewer complications; however, its effectiveness appears to decrease over time.

Anemia is the most common hematologic finding in patients with advanced infections caused by human immunodeficiency virus (HIV) or advanced acquired immunodeficiency syndrome (AIDS). Among many etiologies of HIV-associated anemia, vitamin B12 deficiency plays an important role, mostly due to malabsorption or HIV enteropathy. We experienced a case of megaloblastic anemia caused by vitamin B12 deficiency in a male patient with an AIDS who had no structural gastrointestinal problem. He showed severe anemia, leukopenia, thrombocytopenia and suspicious neurologic manifestations such as aggravation of dementia and gait disturbance. With vitamin B12 and folate treatment, the patient's general condition and hematologic features were improved successfully.
