A 4-year-old girl developed acute motor, sensory impairment, lower abdominal pain and urinary dysfunction after URI. In acute stage of disease, MRI showed diffuse spinal cord swelling and high signal intensity on T2WI below T2 body level. The patient did not improved and one month later, follow-up MRI showed diffuse spinal cord atrophy and syrinx formation as sequelae of ATM on T1WI below T9 level. To our knowledge, this is the first case showing the sequelae of acute transverse myelitis seen in Korea.

Uterine torsion is defined as the mtation of more than 45 degrees around the long axis of the uterus or a rotation which is severe enough to produce symptoms. Torsion of the human pregnant uterus is a very rare complication. The diagnosis is problematic and is often made during a cesrean section due to inhibited labor. Torsion of the human pregnant uterus can be caused by myoma or other uterine abnormalities, ovarian cysts, adhesions, abnormal fetal presentations, or fetal abnormalities ( though no cause can be found in about 20% of cases ). Uterine torsion produces symptoms of varying severity depending on the degree of rotation, and duration of the pregnancy. High mortality rates for both mother and infant have been reported. We experienced one case of the torsion of term pregnant uterus and report this case with a brief review of the concerned literature.

PURPOSE: Chemokines are structurally related, small polypeptide signaling molecules that bind to and activate a family of transmembrane G proteincoupled receptors, the chemokine receptors. Recently, interaction between the chemokine receptor CXCR4 and its ligand, stromal cell-derived factor 1 (SDF-1 or CXCL12), has been found to play an important role in tumorigenicity, proliferation, metastasis and angiogenesis in many cancers such as lung cancer, breast cancer, melanoma, glioblastoma, pancreatic cancer and cholangiocarcinoma. Hence, the goal of this study is to identify the correlation of clinicopathological factors and the up-regulation of SDF-1 expression in oral squamous cell carcinoma. MATERIAL AND METHODS: We studied the immunohistochemical staining of SDF-1, quantitative RT-PCR (qRT-PCR) of SDF-1 gene in 20 specimens of 20 patients with oral squamous cell carcinoma. RESULTS: 1. In the immunohistochemical study of poor differentiated and invasive oral squamous cell carcinoma, the high level staining of SDF-1 was observed. And the correlation between immunohistochemical SDF-1 expression and tumor nodes metastases (TNM) classification of specimens was significant.(chi-square test, P < 0.05) 2. In the SDF-1 gene qRT-PCR analysis, SDF-1 expression was more in tumor tissue than in carcinoma in situ tissue. Paired-samples analysis determined the difference of SDF-1 mRNA expression level between the cancer tissue and the carcinoma in situ tissue.(Student's t-test, P < 0.05) CONCLUSION: These findings suggest that up-regulation of the SDF-1 may play a role in progression and invasion of oral squamous cell carcinoma.

Neurofibromatosis(Von Recklinghausen's disease) is an autosomal dominant disease that affects one in 2,500-3,000 births. The clinical presentation is characterized by multiple pigmented lesions of the skin, known as cafe-au-lait spots, and neurofibromas of the skin. The criteria for diagnosis are at least six cafe-au-lait spots, each greater than 1.5cm in diameter and positive family history and biopsy of a neurofibroma. Management of benign neurofibromatosis must be individualized for each patient and ranges from incisional biopsy to wide local excision. Genetic counseling is advised for all patients with this disease, since no cure is available. We report the case of multiple neurofibromatosis with oral, parapharyngeal space and whole body lesions that was treated with surgical excision.

Many treatment approaches of Cl III malocclusion have been introduced and the choice of treatment should be a function of the individual problem, not of the clinician(personal preference, experience and success rate of the operator). Therefore a function of the individual problem should be analysed exactly. Much has been written in the orthodontic literature concerning the nature of Cl III malocclusion. It has been reported by many investigators that a Cl III malocclusion occurs in a variety of skeletal and dental configurations by differences of race and age. Lateral cephalometric radiographs of 125 individuals were studied for the presence and distribution of four horizontal components and one vertical component in a manner similar to McNamara. The results were as follows 1. Cl III malocclusion is not a single clinical entity. It can result from numerous combinations of skeletal and dental components. 2. Maxillary skeletal retrusion was the most common single characteristic of the Cl III sample. 3 Only a small percentage or the cases in this cases in this study exhibited maxillary dentoalveolar protrusion. 4. Only a small percentage of the cases in this study exhibited mandibular dentoalveolar dentoalveolar retrusion. 5. Mandible was usually well-positioned, but a wide variation was observed. 6. A large percentage of the cases in this study exhibited excessive vertical development. Thus, it appears that in designing the ideal treatment regime, those approaches which might restrict vertical development and promote maxillary horizontal growth could be more appropriate in many cases.

PURPOSE: The purpose of this study was to analyze the expression and localization of Nrf2 mRNA in rats according to the changes of K-diet. METHODS: Nrf2 gene was isolated using DNA chip microassay. Northern and Western blot analysis and in situ hybridization (ISH) were performed. RESULTS: Northern analysis of normal rat demonstrated that Nrf2 mRNA was abundantly expressed in stomach, moderately in testis, kidney, distal colon, duodenum, and adrenal gland, and weakly in brain, heart, spleen, salivary gland, liver, and lung. In the kidney of K-restricted groups, Nrf2 mRNA and protein expressions were gradually increased in K-restricted kidney. By ISH, hybridization signal for Nrf2 gene of normal group was prominent in the S3 segment of proximal tubule, distal tubule, and cortical collecting duct, and weak in outer and inner medullary collecting duct. In K-restricted groups, the localization of hybridization signal was the same as in normal group. Signal intensity of K-restricted groups was markedly increased in outer and inner medullary collecting ducts compared with normal group. But, that of the distal tubule and cortical collecting duct was decreased. mRNA for Nrf2 gene of normal group was detected in the cells of the basal portion of intestinal gland of distal colon and stomach, spermatogonia and spermatocytes of seminiferous tubule of testis, small lymphocytes of germinal center of spleen, and adrenal medulla cells of adrenal gland. CONCLUSION: These results suggest that expression of Nrf2 is different in various tissues and increased expression of Nrf2 gene in outer and inner medullary collecting ducts of hypokalemic kidney could regulate the ion transporter genes by these segments.

Fungal infection of intracardiac pacing wire is very rare. We experienced a case of patient with functioning transvenous pacemaker lead, inserted 3 years previously, which was completely encased in a large thrombus infected with aspergillus. The lung biopsy also confirmed aspergillus infection.
