Isolated dorsal dislocation of the trapezoid is an unusual injury. In 1990 Ostroski found only 15 cases of dorsal dislocation of the trapezoid in the world literature. The trapezoid is a wedge-shaped bone with the larger dorsal and smaller volar surface area, and stabilized by strong palmar ligaments. Therefore the dislocation of the trapezoid is produced hy a violent force against the dorsum of the hand on a rigid object and often associated with other injuries of the hand. The diagnosis is often missed or delayed perhaps secondary to the difficulty in interpreting the X-ray if you have not kept in mind. Several therapeutic modalities are performed from the collected experience of the authors reporting this injury. A rare example of an isolated dorsal dislocation of the trapezoid bone is described.

PURPOSE: The aim of study was to identify the effects of exercise on the relief of low back pain in patients on absolute bed rest after TAE. METHOD: A nonequivalent control group pretest-posttest design research design was used. The participants were 43 patients who had received TAE in a university hospital; patients in the experimental group (21) received both exercise therapy and general post-op nursing care and in the control group (22) only the latter. The exercise program used in this study was modified from exercise for post CABG to exercise for post TAE, which deflect the movement of thigh in which the catheter was inserted, the lumbar region of the back and pelvis. RESULTS: First, Low back pain scores in the experimental group were lower than the control group. Second, The first dose of analgesics in the experimental group was delayed compared to the control group. Third, There was no significant difference in bleeding complications between the experimental group control groups. CONCLUSION: The results suggest that the exercise program used in this study is effective for relief of low back pain in patients on absolute bed rest after TAE.

Although a popliteal cyst is most commonly identified as an asymptomatic mass occurring just below the popliteal fossa, the fluid may further extravasate into a deep compartment, causing compression with symptoms of local pain and tenderness. When the popliteal vein is compressed by a popliteal cyst, it may develop the symptom simulating the deep vein thrombosis, when the popliteal artery is compressed, it may develop the symptom simulating the ischemic pain and intermittent claudication. It is unusual for popliteal cysts to involve a nerve. When such does occur, it usually involves the tibial nerve, very rarely the peroneal nerve. It is important to diagnose a popliteal cyst early and to differentiate it from a ganglionic cyst, thrombophlebitis or a popliteal aneurysm, to effect optimal therapy and to obviate a potential neuropathy. We are now reporting a case of a thirty four-year-old male who had a popliteal cyst causing tibial nerve compression.

PURPOSE: To report a case of multiple serous chorioretinopathy after facial herpes zoster. CASE SUMMARY: A 48-year-old male visited our clinic due to visual disturbance in the left eye which occurred 3 days after left facial pain and vesicles. Chemosis and multiple serous retinal detachments were found. The patient was diagnosed with multiple serous chorioretinopathy due to herpes zoster virus and was started on intravenous acyclovir at a dose of 10 mg/kg every 8 hours for 9 days and herpes eye ointment 5 times daily. After the initial treatment, oral prednisolone 60 mg was given daily for 6 days. Skin lesions were cleared, and abnormal fundus and visual acuity improved after treatment. CONCLUSIONS: Ophthalmopathy including multiple serous chorioretinopathy should be considered in managing herpes zoster ophthalmicus patients.

BACKGROUND: To investigate the role of alpha-adrenergic receptors in the development of delayed afterdepolarization, the effect of alpha-adrenoceptor stimulation and blockade on ouabain induced delayed afterdepolarization(DDAD) was examined in rabbit heart Purkinje fibers. METHODS: Purkinje fibers, taken from adult rabbit(1.8 - 2.0kg) heart anesthetized with penobarbital, were mounted in a Luicite chamber and superfused with Tyrode's solution. The transmembrane potentials were measured by the conventional microelectrode technique while the fibers were being stimulated with rectangular pulses of 50% above threshold voltage. The delayed afterdepolarizations were induced by overdrive excitation in the presence of ouabain. RESULTS: Delayed afterdepolarizations were not observed during superfusion of the control Tyrode's solution containing propranolol(5x10(-7)M). However, the addition of ouabain in the presence of propranolol elicited DADs which were dose-, time- and drive cycle length- dependent. Phenylephrine(PE ; 10(-7)M), and alpha-adrenoceptor agonist, potentiated the ouabain-induced DAD during the initial superfusion(for 10 or 20 min) of the test Tyrode's solution. However, it was followed by attenuating-effects after a superfusion time of 50 to 60 min. Both effects showed ouabain dose-dependence. Ouabain(2x10(-7)M), in the presence of propranolol, depolarized the maximum diastolic potential and shortened the action potential duration, and the addition of PE(10(-7)M) did not affect the characteristics of action potential except a decrease in velocity of phase 0 depolarization. Prazosin, an alpha1-adrenoceptor antagonist, inhibited the PE's enhancing effects of ouabaininduced DDAD at 20 min superfusion, but did not affect the attenuating-effects of PE at 60 min superfusion. On the other hand, yohimbine, an alpha2-adrenoceptor antagonist, did not affect the PE's DAD potentiating-effects at 20 min superfusion, but inhibited the attenunating-effects of PE at 60 min superfusion. CONCLUSION: It is inferred that alpha-adrenergic stimulation induce delayed afterdepolarization and triggered activity in the rabbits, being responsible for the arrhythmia development, and the effects are mainly due to the action of alpha1-subtpe adrenoceptor stimulation.

A subperiosteal ganglion has been very rarely reported, since Ollier reported first one in 1864. A subperiosteal ganglion is produced by mucoid degeneration and cyst formation within the periosteum, which results in cortical erosion. The characteristic plain radiolographic appearance of irregular cortical erosion and scalloping, with reactive periosteal bone spicules, has been considered pathognomonic of subperiosteal ganglion. Magnetic resonance imaging is performed to further characterize the soft tissue component of the mass. As in our patient, the characteristic signal intensities of magnetic resonance imaging are especially useful in identifying the lesion as a ganglion and in defining the lobular nature and the anatomical extent. We report here the case of a 35-year-old female who had a sudperiosteal ganglion of the distal radius.

PURPOSE: To establish new in vitro model systems that better reflect in vivo condition, multicellular tumor spheroids(MTS) and raft culture were developed using cell lines of squamous cell carcinoma(SCCHN) of the head and neck. In these 3-dimensional systems, the expression of cell surface molecules which are important for modulation of physiology of tumor cells were studied with or without the treatment of interferon(IFN)-gamma. MATERIALS AND METHODS: Four SCCHN cell lines were used for MTS and raft culture. The effects of interferon-gamma on SCCHN cells were examined by immunohistochemistry. RESULTS: All cell lines formed MTS, but only Tu-138 showed a good stratification at the air-liquid interface in the raft culture system. Immunohistochemical studies of MTS using monoclonal antibodies revealed a strong staining for MHC class I, no staining for MHC-DR, a weak patch expression of ICAM-1 and a central strong staining for integrin a 6. Staining patterns were similar for the raft cultures except integrin a 6(intense full-thickness positivity). In both systems, IFN-gamma enhanced the expression of MHC-DR and ICAM-1. No significant change was found in the expression of MHC class I and integrin a 6. CONCLUSIONS: MTS and raft culture system were established successfully from the SCCHN cell lines. IFN-gamma can modulate the surface molecules of tumor cells in the 3-dimensional culture systems.
