Ganglion cysts usually arise from the tissues around the facet joints. It is usually associated with degenerative cahanges in facet joints. Bilateral thoracic ganglion cysts are very rare and there is no previous case that located in bilateral intervertebral foramen compressing the L1 nerve root associated with severe radiculopathy. We report a 53 years old woman who presented with bilateral groin pain and severe numbness. Magnetic resonance imaging revealed bilateral cystic mass in the intervertebral foramen between 12th thoracal and 1st lumbar vertebrae. The cystic lesions were removed after bilateral exposure of Th12-L1 foramens. The result of hystopathology confirmed the diagnosis as ganglion cyst. The ganglion cyst may compromise lumbar dorsal ganglion when it located in the intervertebral foramen. The surgeon should keep this rare entity in their mind for differential diagnosis.

Most primary spinal abscesses, irrespective of pathogens and anatomical locations, have better prognosis than that of secondary abscesses with spondylitis. We report a 68-year-old man, previously undertaken pulmonary resection due to tuberculosis, presented with paraparesis. Imaging studies showed primary intraspinal abscesses at T-1 and T-3 vertebral levels, semi-invasive pulmonary Aspergillosis and inflammation of the posterior mediastinum. Operative procedure and histopathological examination revealed interdural Aspergillus abscess. Despite chemotherapy, he deteriorated progressively, and spondylitis developed at corresponding vertebrae. He eventually died 6 weeks postoperatively due to pulmonary complication. The authors intended to inform that such an extradural inflammatory lesion of Aspergillus abscess should be treated carefully.

Hodgkin's disease presenting with spinal cord compression owing to extradural and bone involvement is extremely unusual. A 48-year-old man presented with progressive lower extremity weakness resulting from spinal cord compression attributable to an epidural mass in the thoracic vertebrae. The patient underwent decompressive surgery, and was then treated with chemotherapy for Langerhans cell histiocytosis. However, the disease progressed, and we performed second decompressive surgery with stabilization. Subsequent histopathological investigations revealed Hodgkin's lymphoma of the bone. Here, we describe an unusual case of spinal Hodgkin's lymphoma and Langerhans cell histiocytosis to draw attention to this combination as a possible diagnosis in patients with mixed inflammatory cell infiltrate lesions in the spine.

Psenes arafurensis, belonging to the family Nomeidae, is described based on four specimens (184.8-199.0 mm in standard length) collected from Korea. The species is most similar to the congeneric species P. maculatus and P. pellucidus, but differs from them in the number of lateral-line scales. (44-47 in P. arafurensis vs 67-70 in P. maculatus and 120 in P. pellucidus) and the number of vertebrae (31 in P. arafurensis vs 34-38 in P. maculatus and 40-42 in P. pellucidus). The present study is a new record of P. arafurensis with voucher specimens from Korean waters.

A single specimen of a juvenile Stethojulis trilineata was first collected from the coastal waters of Ulsan, Korea, in October 2012. This species is characterized by IX dorsal fin spines, 26 lateral line scales, 25 vertebrae, dark spots between the 10th and 11th dorsal fin rays, and a caudal peduncle region. The new Korean name proposed is "Se-jul-mu-ji-gae-nol-rae-gi" for S. trilineata.

Three barracudina fishes (Paralepididae) were newly recorded from the southern sea of Korea. Lestidium prolixum is characterized by a single band of luminous ducts on the midventral line and absence of a papilla anterior to the eye. Lestrolepis intermedia and L. japonica are similar in having a black papilla immediately in front of the eye and two bands of luminous ducts on the midventral line. However, the dorsal fin of L. intermedia is located more posterior along the body than that of L. japonica, and L. intermedia have larger number of anal fin rays 42 (vs. 36-40) and vertebrae 95 (vs. 86-87) than L. japonica.

At the early stages of engineering design, a number of design concepts may be suggested. With a great degree of freedom, making a good choice may be a challenge at this stage. In this study, a simplified evaluation criterion for design concepts is presented based on cost, simplicity and safety. Cost is estimated by the amount of materials and the required level of tolerance. Simplicity is represented by the number of parts, assembly steps, and fasteners. Safety is assessed by the level of potential failure. The proposed criterion is applied to an example design of driving mechanisms for cervical vertebrae massage machine.

One specimen of Pteraclis aesticola was collected off San Jose del Cabo, Baja California Sur, Mexico ($22^{\circ}54'N$, $109^{\circ}45'W$), in March 2007. Present record is the first reported occurrence of the species in the Tropical Eastern Pacific biogeographic region (Gulf of California to southern Ecuadorian waters). Its large fan-like anal and dorsal fins and its counts of fin rays and vertebrae can distinguish the Pacific fanfish from the other species in the genus. This fish may have not yet been recorded in the region because its presence has been overlooked in the past because of rarity and lack of commercial value.

Stellate ganglion block is a well established method for the management of certain pain syndromes (e.g., chronic regional pain syndrome, facial pain) in the cervicothoracic region and upper extremity. The stellate ganglion resides between the C7 transverse process and the head of the first rib. Anesthetic injections for the stellate ganglion block are typically made at the level of the transverse process of either the C6 or C7 vertebrae to avoid the pleura, vessels, and nerve roots. Method of positioning the needle tip directly at the ganglion has been described, but are problematic because of the risk of injury to or injection into adjacent structures. It is necessary to know the exact anatomic position of the stellate ganglion when permanent blockade is required by means of radiofrequency thermocoagulation. Whereas fluroscopy shows only bony feature, computerized tomography also images nerves, vessels, and lung, allowing accruate needle placement. We report a case of the percutaneous radiofrequency thermocoagulation of the stellate ganglion after computerized tomography-guided localization.
