Reversible splenial lesion syndrome can be caused by viral infection. Rubella generally occurs in childhood, and it is rarely accompanied by neurological complications in adulthood. A 35-year-old man visited our hospital due to conjunctival injection, mild fever, and headache 3 days after experiencing skin rash. Brain magnetic resonance imaging (MRI) revealed distinct lesions involving white matter in the splenium of the corpus callosum approximately 3 days following the onset of symptoms. Enzyme immunoassay performed on serum and CSF samples was positive for rubella virus IgM. A follow-up brain MRI was performed 24 days after the onset of symptoms, and reduced lesion size with decreased signals were observed on diffusion weighted image. This case showed that rubella infection can result in reversible splenial lesion accompanied by only mild neurological symptoms.

We performed dual color fluorescence in situ hybridization (FISH) for the bcr/abl fusion in CML using the peripheral blood smears without destruction of cell morphology to determine the bcr/abl fusion. Two patients of CML, one patient in accelerated phase and one patient in chronic phase, were selected. The blood smears were fixed in absolute methanol. FISH was performed with the Mbcr/abl translocation DNA probe mixture and the slides were stained with Wright's stain after FISH. The blood smears of both cases revealed distinct signals without destruction of cellular morphology. The normoblasts and lymphocytes revealed beautiful fused bcr/abl signals as well as granulocytes in both cases. The results provide a novel finding that the normoblasts and lymphocytes in CML are also neoplastic clonal cells which has not been demonstrated with a single-cell approach before.

PURPOSE: We use many electronic devices for treating patients in our emergency department. Several studies have reported an association between electromagnetic field exposure and risk of cancer and other diseases. Our purpose was to measure the intensity of power-frequency magnetic fields in the emergency department and evaluate the conditions exceeded regulation guidelines for power-frequency magnetic fields. METHODS: Extremely low frequency magnetic fields were measured at 78 ordinary working spots in our tertiary hospital's emergency department (ED) and evaluated according to national regulatory guidelines and SWEDAC. Each spot was measured four times. During measurement, every electrical device in the emergency department was turned on. RESULTS: The average intensity of the magnetic fields in our emergency department was 0.99+/-1.27 mG. The maximum intensity was 8.3 mG, which was found in the pediatric section. CONCLUSION: The power-frequency magnetic field intensities of the various sections of our ED did not exceed national regulatory guidelines. However, pediatric and the minor emergency section showed magnetic fields intensities far above 2 mG. We found these high values outside the pediatric and waiting sections, where the electrical cabinet panel was located. We conclude that the electrical cabinet panel should be shielded and that similar studies are needed for other emergency departments.

Although liposarcomas are second most frequently encountered sarcomas that occur in soft tissue, liposarcomas of the head and neck are very uncommon. Liposarcomas of the retropharyngeal space are rare and do not cause symptoms until they reach a large size to cause mass effect. Depending on the location of the pharyngeal tumor, patients may present with foreign body sensation on throat, swallowing difficulty, respiratory difficulty, a painless neck mass, or obstructive sleep apnea. Recently we have experienced a case of retropharyngeal liposarcoma causing obstructive sleep apnea, so we report our clinical experiences with a brief review of literature.

Peripheral T cell neoplasms (PTCNs) comprise a group of uncommon and heterogenous lymphoid malignancies. They are more difficult to diagnose and treat and have a worse prognosis than B cell lymphomas. NK/T cell lymphoma is the most common histologic subtype in the head and neck. Unspecified type is the most common subtype of PTCNs but is not reportedin oral cavity or nasal cavity. We report a case of a perforating palatal ulceras a rare presentation of peripheral T cell lymphoma with a review of literature.

Nevus sebaceous is a rare tumor in the external ear. It is clinically important because this tumor has chance to progress to benign or malignant neoplasm. This change generally occurs after adolescent age. The most common malignant neoplasm arising in this lesion is basal cell carcinoma. Therefore, many authorities recommend complete excision before puberty. A 9-year-old boy visited our clinic with multiple nevi sebaceous involving the pinna and external auditory canal. The tumors were removed completely and the defect was covered with skin graft. There has been no evidence of recurrence as of 10 months following the surgery. We report this case with a review of literature.

PURPOSE: To evaluate mid to long term results of Elmslie-Trillat-Marquet procedures for recurrent patellar subluxation or dislocation. MATERIALS AND METHODS: From May 1993 to February 2004, 21 knees in 20 patients who got Elmslie-Trillat-Marquet procedures were evaluated. Mean follow-up periods were 80.5 months. Clinical tests such as Lysholm knee scoring scale, IKDC subjective knee evaluation form, visual analog scale and radiological tests such as Insall-Salvati index and congruence angle were evaluated. RESULTS: Lysholm knee score was improved to average 91 points, IKDC knee score 82, visual analog scale 28. Q angle was improved from average 28degrees preoperatively to 12.5degrees. Insall-Salvati index and congruence angle were significantly corrected and no subluxation or dislocation were observed at final follow up. Fracture of tibial tubercle in 1 case which was treated with refixation and medial instability in 3 cases were observed. CONCLUSION: Elmslie-Trillat-Marquet procedure can be a useful method to correct patellofemoral malalignment in long term follow up but meticulous care to reduce the complication was needed.

OBJECTIVE: To study the acromial type, acromial angle, acromial tilt and subacromial distances which known as extrinsic factors of subacromial impingement syndrome in groups of subacromial impingement syndrome and normal control. METHOD: The radiography of shoulder named shoulder series composed of AP view, arch view and impingement view was performed in thirty patients with subacromial impingement syndrome and ninety persons with normal adult and we measured the acromial type, acromial angle, acromial tilt, subacromial distances and subacromial spur. RESULTS: Mean subacromial distances of impingement group were 11.3+/-2.4 mm in AP view, 11.1+/-2.5 mm in arch view and those of normal control group were 11.1+/-2.2 mm in AP view, 10.4+/-1.9 mm in arch view. Incidences of acromial type I,II,III in impingement group were 15 (50%), 10 (33.3%), 5 (16.7%) respectively and those in normal control group were 20 (22.2%), 46 (51.1%), 24 (26.7%) respectively. Incidence of subacromial spur was 19 (63.3%) in impingement group and 52 (57.8%) in normal control group. Mean subacromial spur size was 10.0+/-5.4 mm in impingement group and 12.4+/-4.5 mm in normal control group. Mean acromial angle was 27.1+/-8.3 degree in impingement group and 29.1+/-8.7 degree in normal control group. Mean acromial tilt was 28.0+/-6.39 degree in impingement group and 31.8+/-3.4 degree in normal control group. CONCLUSION: No significant statistical difference between subacromial impingement syndrome group and normal control group in acromial type, acromial angle, acromial tilt and subacromial distance known as extinsic factors of subacromial impingement syndrome.

Vestibular neuritis is commonly diagnosed by demonstrating of peripheral vestibular failure as a unilateral loss of the caloric response. It is a sudden, spontaneous, unilateral loss of vestibular function without simultaneous hearing loss or brainstem signs. In most patients with vestibular neuritis, the process is thought to involve the superior vestibular nerve. Very rarely, vestibular neuritis involves only the inferior vestibular nerve. We experienced a 56-year-old male with inferior vestibular neuritis. The patient had vertigo and spontaneous nystagmus, but a normal caloric test. Brain magnetic resonance imaging was normal, while vestibular evoked myogenic potentials had absent amplitudes on the lesion side. The patient was thought to suffer from pure inferior nerve vestibular neuritis.

The authors analyzed 28 cases with hypertensive cerebellar hemorrhage, diagnosed by computerized tomography(CT), between 1987 and 1990, in Chonbuk National University Hospital. The authors assessed the relationship of outcome to the CT appearance of the quadrigeminal cistern, which in some cases was obliterated by rostral displacement of the vermis resulting from the cerebellar mass. Obliteration of the quadrigeminal cisterns was classified on the CT scans into three grades:Normal(Grade I), Compressed(Grade II), or Absent(Grade III). There were 7 cases with Grade I, 9 with Grade II, and 12 with Grade II cisterns. Of the 28 cases, 6(85%) of those with Grade I, 7(78%) of those with Grade II, and none of those with Grade III cisterns respectively returned to their previous activities at 6 months or more after onset. A Grade I cisterns predicted a good outcome whether the hematoma was evacuated or not, as long as obstructive hydrocephalus, if present, was relieved early. However, a Grade II cistern was not predictive of a good outcome unless the hematoma was evacuated within 48 hours after onset of the hemorrhage. A Grade III cisterns predicted an unfavorable outcome. Taken together, these results strongly suggest that the CT grade of quadrigeminal cistern obliteration may be an indicator of outcome and may be useful in selecting treatment for patients with cerebellar hemorrhage.
