Traumatic rupture of the superior oblique muscle is rare. We report a case of a 54-year-old man injured by the metal hook of a hanger, resulting in a rupture of the superior oblique muscle tendon. He complained of torsional diplopia when in the primary position. The distal margin of the superior oblique muscle was reattached to sclera 5 and 9 mm apart from the medial insertion of the superior rectus muscle. One week after the operation, torsional diplopia disappeared. However, a 4-prism diopter ipsilateral hypertropia was observed. Three months later, hypertropia gradually increased to 20 prism dioptors and the second operation was done to correct vertical diplopia.

Cytologic findings of pleural effusion in three cases of rhabdomyosarcoma are reported. Case 1 was a pleomorphic rhabdomyosarcoma which had devoped at the chest wall of an elderly male patient and caused pleural effusion. The cytologic features were consistent with pleomorphic rhabdomyosarcoma, that was, showing loose clusters, cellular pleomorphism, and abundant finely vesicular cytoplasm. Cases 2 and 3 were embryonal rhabdomyosarcomas in young adults. Primary site was the oral cavity in case 1, but unknown in case 2 and case 3. The effusion cytology was similar in these cases. Clustered or isolated small round cells with hyperchromatic nuclei and scanty cytoplasm were smeared. The cohesiveness of tumor cells was weak and the cells did not show linear arrangement or nuclear molding. Effusion cytology in a sarcoma patient would be diagnostic when the primary site and the type of sarcoma were already known.

PURPOSE: This study evaluated the treatment effectiveness and proper radiation dose of helical tomotherapy (HT) in spine oligometastases from gastrointestinal cancers. MATERIALS AND METHODS: From 2006 to 2010, 20 gastrointestinal cancer patients were treated with HT for spine oligometastases (31 spine lesions). The gross tumor volume (GTV) was the tumor evident from magnetic resonance imaging images fused with simulation computed tomography images. Clinical target volume (CTV) encompassed involved vertebral bodies or dorsal elements. We assumed that the planning target volume was equal to the CTV. We assessed local control rate after HT for 31 spine metastases. Pain response was scored by using a numeric pain intensity scale (NPIS, from 0 to 10). RESULTS: Spine metastatic lesions were treated with median dose of 40 Gy (range, 24 to 51 Gy) and median 5 Gy per fraction (range, 2.5 to 8 Gy) to GTV with median 8 fractions (range, 3 to 20 fraction). Median biologically equivalent dose (BED, alpha/beta = 10 Gy) was 52 Gy10 (range, 37.5 to 76.8 Gy10) to GTV. Six month local control rate for spine metastasis was 90.3%. Overall infield failure rate was 15% and outfield failure rate was 75%. Most patients showed pain relief after HT (93.8%). Median local recurrence free survival was 3 months. BED over 57 Gy10 and oligometastases were identified as prognostic factors associated with improved local progression free survival (p = 0.012, p = 0.041). CONCLUSION: HT was capable of delivering higher BED to metastatic lesions in close proximity of the spinal cord. Spine metastases from gastrointestinal tumors were sensitive to high dose radiation, and BED (alpha/beta = 10 Gy) higher than 57 Gy10 could improve local control.

Various cancer types have been associated with cancer-related cerebral infarction. In this study, we
describe the first case of cancer-related cerebral infarction in which the underlying disease was primary
bone marrow lymphoma (PBML). A 79-year-old man presented with abruptly developed bilateral lower
extremity weakness and confusion. Diffusion-weighted imaging on admission showed multiple cortical
and subcortical embolic infarction lesions in multiple vascular territories. Diagnostic evaluations to
determine the embolic source revealed no abnormalities. Laboratory testing demonstrated elevated
D-dimer (2.59 μg/mL) but no other prothrombotic abnormalities. In suspicion of cancer-related stroke,
we performed chest CT, abdomen CT, and FDG-PET to detect the hidden malignancy. Findings
revealed no evidence of cancer; however, they did reveal signs of anemia (hemoglobin 9.0 g/dL).
Bone marrow aspiration biopsy showed large atypical B cell involvement suggestive of high-grade B
cell lymphoma. The patient was diagnosed with primary bone marrow diffuse large B-cell lymphoma
initially presenting with ischemic stroke. Our case suggests that primary bone marrow cancer may be a
candidate for the differential diagnosis of hidden malignancy in patients with suspected cancer-related
stroke. Bone marrow biopsy may be essential for establishing an appropriate differential diagnosis in
patients with abnormal hematologic findings.

It is difficult to analyze the chemical compositions of aqueous humor because of the impossibility of collection of aqueous humor in normal situation, lack of analyzing technique, limited amount of aqueous humor. We measured the glucose concentration of aqueous humor both in cataractous patients with diabetes mellitus and in cataractous patients without diabetes mellitus, thus we compared and analyzed glucose concentration in aqueous humor and correlation between blood glucose con centration and aqueous humor glucose concentration in cataractous patients with diabetes. The mean concentration of glucose in aqueous houmor in diabetics was 92.81 +/- 35.58mg/dl and that of non-diabetics was 53.62 +/- 34.42mg/dl. Aqueous glucose concentration in diabetics was statistically significantly higher than that in non-diabetics.

PURPOSE: To evaluate the tear meniscus in aqueous tear-deficient dry eye patients using Fourier-domain optical coherence tomography (FD-OCT) and to investigate the clinical usefulness of tear meniscus values. METHODS: The present study included 79 aqueous tear-deficient dry eyes and 50 normal eyes. Tear meniscus height (TMH), tear meniscus depth (TMD), and tear meniscus area (TMA) were imaged using FD-OCT and measured with computer calipers. Schirmer's test, tear break-up time, and corneal fluorescein staining were also performed and the correlations between the tests were analyzed. Additionally, the diagnostic power of tear meniscus values was compared using area under the receiver operating characteristic curve (AUROC). RESULTS: Tear meniscus values were significantly decreased in the aqueous tear-deficient dry eye group (p < 0.05). TMH, TMD, and TMA were positively correlated with Schirmer's test and tear break-up time (p < 0.05), and TMH and TMD were negatively correlated with corneal fluorescein staining in the aqueous tear-deficient dry eye group (p < 0.05). The AUROCs of TMH, TMD, and TMA were 0.978, 0.788, and 0.957, respectively. CONCLUSIONS: Tear meniscus values measured using FD-OCT were significantly lower in aqueous tear-deficient dry eyes and were correlated with Schirmer's test, tear break-up time, and corneal fluorescein staining. Tear meniscus measurements obtained using FD-OCT can be useful clinical parameters for the diagnosis and treatment of aqueous tear-deficient dry eye.

Congenital onychodysplasia of the index fingers(COIF) is a rare condition of the nails, characterized by the following : (1) congenital occurrence, (2) unilateral or bilateral index finger involvement, (3) variability in nail appearance such as anonychia, micronychia, and polyonychia, (4) possible hereditary involvement, and (5) frequently associated bone anomalies. A 7-week-old male baby with an atrial septal defect presented with micronychia of the left index finger. Roentgenogram of both hands revealed a bone defect of the left 2nd distal phalanx. To our knowledge, distal phalangeal bone defect has not been previously described in this disease. We report a case of COIF with atrial septal defect.

Malignant tumors of the maxilla represent about 3-4% of head and neck malignant neoplasm and the origins are maxillary gingiva, hard palate and maxillary sinus. We are to investigate clinical features and results according to various treatment modalities of maxillary malignant tumor to get information for better treatment results. Sixty patients with malignant maxillary tumors treated at Yonsei medical center from 1992 to 1997 were studied retrospectively. They are evaluated according to clinical signs & symptoms, stages at first diagnosis, primary site, histopathologic features, treatment method, recurrence and survival rate with clinical records, biopsy results and CT radiograph. The most common primary site was maxillary sinus and most common histopathology was squamous cell carcinoma. The local recurrence rate was 18% at 5 years, neck failure was 3% and distant metastasis was 18%. Overall survival rate was 78% at 2 years and 69% at 5 years. Failure at primary site is the main problem in the curative treatment. So, to improve survival in these patients efforts should be directed toward improvement of local control.

PURPOSE: To report a rare case of conjunctival myxoma invading the caruncle. CASE SUMMARY: A 46-year-old man presented with a medical canthal conjunctival mass in his left eye. The mass was a semi-transparent, yellowish, movable mass 10 mm x 6 mm in size in the subconjunctival space. There was no pain and no tenderness. Excisional biopsy of the mass was performed. Histopathologic examination revealed findings suggestive of myxoma. CONCLUSIONS: Relatively transparent, movable, yellowish to pinkish conjunctival masses at medial canthal area without pain or tenderness can be diagnosed as myxoma on biopsy and myxoma can be seen at caruncle.
