Toll-like receptor (TLR) 3 is a member of the TLR family that confers innate immunity by recognizing viral pathogens. Herein, we report that the TLR3 isoform is expressed on human primary cells and cell lines. This isoform has 2, 520 bp cDNAs compared to the 2, 712 bp of full cDNA, is produced by deletion of an intron-like sequence within exon 4 and is co-expressed with wild type TLR3 in primary human astrocytes and glioblastoma cell lines. This finding suggests the TLR3 isoform in astrocytes may have a different immunological role for binding ligands during the immune response in brain.

Mesenteric cysts are rarely thought of, may be difficult to diagnose, and are usually asymptomatic except when complicated. Intestinal obstruction is a rarely reported complication of these cysts. A case of mesenteric cyst that was causing obstruction of the large bowel is presented, along with a review of the literature.

Centronuclear myopathy (CNM) is a rare congenital myopathy that is characterized by centrally placed nuclei in the muscle fibers. Based on the time of onset and the mode of inheritance, CNM can be divided into three distinct forms: the severe neonatal form, the childhood onset form, and the adult onset form. This paper describes the case of a female patient with CNM, in whom the disease manifested itself in the fifth decade of life, without any prior family history of such disorders. To the best of our knowledge, this is a rare case of late adult-onset CNM.

A newly reported, variant form of venous thromboembolism (VTE), named as "eThrombosis", occurred in a patient who maintained a prolonged sitting position at a computer. The patient fortunately recovered from the disease through early diagnosis and treatment. Recently however, the author experienced a new case of a 24-year-old Korean man who died due to "eThrombosis" after playing an Internet computer game continuously for about 80 hours. Based on this case, the author would like to warn heavy computer users of the risk of "eThrombosis", as they might also be at risk. Sitting for a long time at the computer results in an immobility that is a new and large risk factor of life-threatening VTE.

The authors report on a case of primary malignant melanoma of the 7th cervical spinal nerve root in a 45-year-old woman. Neuro-radiological features of this extra-dural mass were suggestive of a nerve sheath tumor. The lesion underwent total gross resection through the anterolateral approach. The patient's postoperative course was uneventful. Histopathological investigation confirmed malignant melanoma. There was no evidence of tumor recurrence or other melanotic lesions on regular follow-up examinations until the postoperative eighth month. When treating a common, benign-looking lesion of the cervical spinal nerve root, surgeons should be aware of the potential to encounter such a malignant tumor.

Klinefelter's syndrome is one of the most common forms of primary hypogonadism and infertility in males. It is characterized by small and firm testes, gynecomastia, azoospermia, and an elevated gonadotropin level. The frequencies of diabetes mellitus, breast cancer, and germ cell neoplasia increases in Klinefelter's syndrome. We report upon a 35 year-old male patient with Graves' disease in association with Klinefelter's syndrome; as confirmed by chromosome analysis. The patient is being treated with antithyroid medication for Graves' disease and by testosterone replacement for Klinefelter's syndrome.

Phenytoin-induced gingival overgrowth is a well-known and frequently reported gingival lesion, which was first detected in 1939. However, there are conflicts in the literature about the agents which affect the severity of the lesion. Un-cooperative dental patients are one of the most unsuccessfully treated periodontal patient groups because of the difficulty in maintaining their oral hygiene. This case report consists of two cases with the same characteristics: phenytoin usage, comprehension and speech defects and poor oral hygiene, but each case differs in the duration of the phenytoin therapy. Both of the cases received scaling, root planning and a gingivectomy.

We report the first Turkish patient with Floating Harbor Syndrome (FHS). The 12-year old male patient exhibited classical dysmorphic features of FHS, mental retardation, celiac disease and additional undescribed findings: microcephaly and cryptorchidism.

We report an unusual case of acute myelogenous leukemia in a patient who showed an extramedullary relapse in her uterus, without bone marrow recurrence, two years after an allogeneic bone marrow transplant. She complained of irregular vaginal spotting, and magnetic resonance imaging demonstrated a uterine mass. A biopsy revealed a massive infiltration of immature myeloid cells. A variable number of tandem repeats (VNTR) based on an examination of peripheral blood cells showed full donor chimerism. After receiving chemotherapy, her uterine mass had completely resolved. She has remained in complete remission for more than 6 months. This case suggests that physicians should be aware of the possibility of a uterine relapse in female bone marrow transplant recipients with acute myelogenous leukemia.

Azodicarbonamide is a low molecular weight foaming agent for plastics and rubbers. Azodicarbonamide can elicit acute and chronic health related problems due to its potential for pulmonary and cutaneous sensitization. Some cases of occupational asthma associated with exposure to azodicarbonamide have been reported, of which only a few cases were confirmed by specific inhalation challenges. Here, the first case of occupational asthma due to azodicarbonamide in Korea, in which the diagnosis was confirmed by specific inhalation challenge, is reported.
