Pars interarticularis fracture is a common finding in young soccer players with low back pain. Spondylolysis in young adults involves a defect of the pars interarticularis, occurring as a result of repeated hyperextension and rotation. Here, we describe the case of a 26-year-old male elite soccer player who was diagnosed with L3 spondylolysis 2 years previously. He visited Incheon Himchan Hospital again because of low back pain. Radiographs showed consecutive spondylolysis at the L3 and L4 levels. Physicians should be aware that repeated performance of athletic movements, such as those during soccer, might lead to consecutive levels of spondylolysis.

Purpose This article evaluate the usefulness of three-dimensional reconstructive images using multi detector computed tomography (MDCT) in thoracic traumatic patients visiting emergency room clinics for out-patients. Materials and methods 76 patients with fractures of 105 patients who visited our emergency room complaining of thoracic trauma were analyzed retrospectively. All patients performed thoracic MDCT and three-dimensional reconstructive images were taken. Fractures were confirmed by axial CT, clinical information, whole body bone scan, and multi planar reformation images. Plain x-ray was analyzed by fractured sites in a blind comparison of two radiologists’ readings, and then that finding was compared with them of axial CT scans and three-dimensional reconstructive images. Results The fracture sites were rib (n=68), sternum (n=14), clavicle (n=6), scapula (n=3), spine (n=5) and combined fractures (n=14). Plain x-ray and axial CT scans had correspondency of 0.555 for rib fractures. Axial CT scans and three-dimensional reconstructive images had 0.952. For sternal fracture, those were 0.692 and 0.928 each. Axial CT scans and three-dimensional reconstructive images showed sensitivities for rib and other fractures, 94 % and 91 % and for sternal fracture, 93 % and 100 % each. Three-dimensional reconstructive image had high sensitivity in the diagnosis of sternal fracture especially. Conclusion While evaluating thoracic trauma at emergency room, three-dimensional reconstructive image was useful to diagnose extent of fracture easily and very sensitive to detect sternal fracture.

Purpose: The possible toxic effect of chronic neuroleptic drug on the neuroendocrine system has been well documented, and hyperprolatinemia is a common side-effect of antipsychotics. Recently we experienced 12 schizophrenic patients with pituitary lesions. It can be postulated that pituitary dysfunction may cause schizophrenia, or neuroleptic drugs may induce pituitary lesion in the patient with schizophrenia. We analyzed these patients and reviewed related literatures. Materiala and Methods: From October 2007 to April 2009, ten patients who had been treated at department of psychiatry under the diagnosis of schizophrenia (6 patients) and other psychiatric diseases (6 patients) were enrolled in this study. The pituitary lesions were detected by MRI and consulted to neurosurgical department. Various possible clinical information, medication history, radiological finding and result of neurosurgical management were analyzed. Result: Radiological findings of twelve patients with pituitary lesions were definite pituitary tumors in 6, cystic lesions in 3 and suspicious tumorous lesions in 3 patients. Medicated drugs at psychiatric department were risperidone, clozapine and other antidepressants. We had operated for 4 patients who had schizophrenia concomitant with definite pituitary tumors. After surgery psychological symptoms of these patients were improved in spite of minimized neuroleptic drugs. The pituitary lesions in the none operated patients were diminished or unchanged during the suitable observation period. Conclusion: Neuroleptic drug may act as toxic effect on pituitary gland by blocking predominantly dopamine receptors of the D2 class as well as other receptors to varying degrees. We experienced 10 psychiatric patients with pituitary lesions. It may be considered that neuroleptic drugs enhance pituitary lesions, or high prolactin level aggravates schizophrenic symptoms.

Hollow-type microneedle array can be used for painless, continuous and stable drug delivery through a human skin. The needles must be sharp and have sufficient length in order to penetrate the epidermis. An array of hollow-type silicon microneedles was fabricated by using deep reactive ion etching and HNA wet etching with two oxide masks. Isotropic etching was used to create tapered tips of the needles, and anisotropic etching of Bosch process was used to make the extended length and holes of microneedles. The microneedles were formed by three steps of isotropic, anisotropic, and isotropic etching in order. The holes were made by one anisotropic etching step. The fabricated microneedles have 170 ㎛ width, 40 ㎛ hole diameter and 230 ㎛ length.

Radio frequency coil which is capable of transmit and receive the signal has been used for image production in magnetic resonance imaging(MRI). Tuning and matching characteristic of radio frequency coil is major factor determining the image quality. In experiment the used coil was called a staircase type coil which is simplified the birdcage coil and referred to a simple LC resonant circuit. Because the inductance values of the coils are fixed coil performance was examined by changing of the capacitance values. In this study capacitance values were experimentally determined to increase of-tuning and matching effect in junction of the coil between coil endring and BNC cable to obtain the high quality of image.

X선 촬영에 있어서 관전압과 피사체가 농도 및 선량에 미치는 영향의 실험 (1)

Author investigated the density and dosage with various thickness of acryl phantom, field size and X-ray tube voltage. The obtained results can be summerized as follows : 1. The effect of density was much as applied voltage was lower, the thickness of object was thicker. 2. The variety of density by the variety of field size was nearly constant when the applied voltage and the thickness of Object was constant. 3, The transmission dose was much decreased when the applied voltage was higher, the thickness of Object was increased. Therefore it is thought that we needed to consider the applied voltage and objects if we make film density and n-value proper.
