  • Purpose: To compare clinical characteristics of ganglions in hand & Foot. Materials and Methods: Seventeen cases of ganglions located in foot and fifty-five cases in hand. Excised from Mar.1988 to Apr.2003, were included in the study. The clinical characteristics and recurrence ratio were evaluated Results: The mean size of 2.2 cm in hand and 2.5 cm in foot. The most common area of ganglions are dorsum of foot and wrist. The cosmetic problem of palpable mass is the primary chief complaint of ganglions on hand and the pain is that of foot. The recurrence was found in 5 cases in hand and 4 cases in foot. The recurrence was related to incomplete excision of ganglion in foot and the large size of ganglion and incomplete excision of ganglion in hand. Conclusion: recurrence ratio in the cases of foot is higher than that of hand. The ganglions in foot and hand need to treated by meticulous surgical excision to prevent the recurrence.

  • Simple ganglions are most common benign tumor of the hand and wrist. However, cystic adventitial disease is an uncommon vascular anomaly first described in 1947 in the external iliac artery. It usually involves the popliteal artery, although other arteries and veins may also be involved. Radial artery adventitial cysts are found directly within the adventitia, whereas the more common wrist ganglions may extrinsically compress or adhere to the artery walls. The diagnosis is rarely made before surgery because of their similar appearance and location. The authors report a rare case of a 46-year old woman with mucoid adventitial cyst of the radial artery in the wrist.

  • Purpose: To evaluate the results of surgical treatment and relationship between the recurrence and characteristics of ganglions in foot and ankle. Materials and Methods: Seventeen cases of ganglions located in foot and ankle, excised at St. Benedict Hospital from Mar. 1993 to Apr. 2003, were included in the study. All of cases were analyzed retrospectively in terms of age, sex of the patients, location and size of the ganglion, symptom, operative method as well as recurrence rate were evaluated. The mean follow up was 1.8 years (11 months${\sim}$6.5 years). Results: The size of ganglion ranged from 0.5 cm to 5.0 cm with mean size of 2.5 cm. The most common area of ganglion was the dorsum of foot and pain was the primary chief complain. The recurrence was found in 4 cases (23.5%): 1 of them occurred among 8 cases the diameter of which was less than 2.5 cm and other 3 occurred among 9 cases larger than 2.5 cm. 12 cases were completely excised mass with no recurrence. But 5 cases were incompletely excised & ligated stalk of mass and 4 cases of them were recurred. A correlation was only observed between complete excision and low recurrence rate. Conclusion: Recurrence rate of ganglions in foot and ankle was high and the correlation was obtained between complete excision and low recurrence rate.

  • Purpose: To analyze the clinical results of excision of the symptomatic or recurred ganglion cysts of the foot and ankle. Materials and Methods: Twenty-one cases of the ganglions located in the foot and ankle area were followed for more than 12 months postoperatively. There were 9 males and 12 females, and the mean age was 42.3 years (range, 11-71 years). The mean duration of follow-up was 2.3 years (range, 1.1-4.1 years). Clinically previous treatment, size and location of the cyst, preoperative and postoperative AOFAS foot score, postoperative complication and satisfaction of patients were evaluated. Results: As a previous treatment, 7 patients received mean 1.3 bouts of aspirations, and 6 patients were recurred after mean 1.5 bouts of operations. The size of cyst ranged from 1.4 cm to 5.1 cm with the mean size of 2.7 cm. The cyst was most common in the dorsum of the foot and ankle, where 14 cases were found. Preoperative mean AOFAS foot. scores were low in the cysts associated with the tarsal tunnel syndrome, which was 71 points, and in the cyst of the plantar aspect of the 1st toe, which was 79 points. Postoperative mean AOFAS foot scores were significantly increased to 91 points and 92 points in preceding two groups. There were 2 cases (9.5%) of recurrence, both of which had satellite mass along the tendon sheath. Conclusion: Care should be taken in the diagnosis and treatment of ganglions in the tarsal tunnel and in the plantar aspect of the 1st toe. In case of ganglion cysts originated from the tendon sheath, consideration should be given for possible satellite mass.

  • Thoracic sympathetic nerve block has a wide range of therapeutic applications which clinicians utilize neurolytics or perform operative sympathectomy. All methods have advantages and disadvantages. We performed "thoracic sympathetic ganglion cauterization" using resectoscope as it is less invasive and more effective than traditional operative methods. Successful procedures were performed involving 2 cases of idiopathic hyperhidrosis and 1 case of sympathetically maintained pain on chest and upper extremity. We experienced failure with one case of idiopathic hyperhidrosis due to severe pleural adhesion. There was also a case of complication of periganglional hemorrhage and parenchymal lung perforation which we successfully treated.

  • In human, sympathetic nerve blocks with local anesthetics are widely used to treat a variety of diseases in the innervating regions. However, its procedure in dogs is difficult to approach and process repeatedly because of anatomically location. Therefore, this study was designed to develop a new technique of sympathetic nerve block in beagle dogs. Fifteen healthy beagle dogs, which did not show any neurologic abnormalities and disease, were used for the study. Radiograghs were taken after injected radiopaque material mixed with 2% lidocaine at the cranial cervical ganglion and injected methylene blue using the same percutaneous technique to verify the reliability of this newly developed technique. The successful block rate of the cranial cervical ganglion block was present in 80% of all dogs and the stained cranial cervical ganglions were shown in all dogs. The results show that this new technique of the cranial cervical ganglion block is a reliable and simple method that can be used for clinical studies in dogs.

  • Paraganglioma is a rare tumor of paraganglia, derived from neural crest cells in sympathetic or parasympathetic ganglions. It can be widely distributed from the skull base to the bottom of the pelvis. The pancreas, however, is a rare location of this neoplasm, and only a limited number of cases have been reported in the English literature, especially with gadoxetic-acid-enhanced magnetic resonance imaging (MRI) and diffusion-weighted images (DWI). We herein report a case of pathologically proven paraganglioma in the pancreas head with a literature review on endoscopic ultrasonography (EUS), computed tomography (CT), gadoxetic-acid-enhanced MRI, and DWI sequence.

  • Five kinds of neurosecretory cells (type-A, B, C, D and E) and neuropiles surrounding them were observed in the visceral ganglion and the right parietal ganglion of the African giant snail, Achatina fulica, by transmission electron microscopy. Type-A cells (diameter, $35{\mu}m$) are the most popular cells in the cortex of the two ganglions, which are of triangular or irregular forms. In their cytoplasm, there are found large granules of 1 fm in diameters and small round granules of about $0.1{\mu}m$ in diameters. Small granules are classified into the ones of high electron density and the others of middle electron density. Type-B cells (diameter, $19\times12{\mu}m$) are evenly distributed over various portions of cortex and medulla of the two ganglions. They are similar to type-A cells in shapes. The cytoplasm of type-B cells is crowded with high electron dense granules of about $0.1{\mu}m$. Round granules of about $0.7{\mu}m$ in diameters are also found but rarely. Type-C cells are the smallest cells whose sizes are about $8\times6{\mu}m$. Each of them contains a large nucleus of about $6\times5{\mu}m$. Its cytoplasm is full of electron dense granules of about $0.23{\mu}m$, each of which is artually an assembly of tiny granules of about $0.03{\mu}m$. Type-D cells are middle-size cells of about $28\times20{\mu}m$, which take ellipsoidal or irregular forms. They are found in the cortex more than in the medulla. Their cytoplasm looks dark due to the high electron density and, in it, two kinds of round granules whose sizes are $1.6{\mu}m$fm and $0.6{\mu}m$, respectively, are observed. Type-E cells are large cells of about $100\times50{\mu}m$, which are rarely found in the upper and middle portions of the two ganglions. The nucleus of the cell, which is very large $(70\times30{\mu}m)$ for the cytoplasm, contains electron dense round granules of diverse sizes (diameters, $1\sim0.2{\mu}m$). The surface of the cell protrudes filopodia of various forms and phagocytizes decrepit cells. Neuropiles are surrounding the neurosecretory cells. In nerve fibers, synaptic vesicles are observed, which are classified into six classes according to their electron densities , sizes and shapes.

  • Programmed cell death (PCD) is thought as a well-controlled process by which unwanted cells are selectively eliminated. During the last decade many researches have elucidated molecules and their interactions involved in cell death by using largely in vitro induction of cell death or survival signals in a more defined manner, While these critical information and novel findings provide us with clearer understanding of mechanisms underlying cell death, it does by no means explain how PCD occurs and which cells or tissues are affected during normal embryonic development in vivo. In this study, we used zebrafish to examine whether the PCD is occurring selectively or randomly in developing embryos by whole mount in situ TUNEL analysis with specific markers for neural cells. The result revealed that the degree and distribution of TUNEL staining varied considerably throughout gastrulation stage, and there was also a number of TUNEL-negative embryos. Most of TUNEL-positive cells were scattered randomly throughout the blastoderm. During the gastrulation stage about 75 % of the embryos analyzed exhibited more than 5 TUNEL-positive cells. As the dorsal epiblast begins to thicken rather abruptly near the end of gastrulation, TUNEL-positive cells were mainly located along the dorsal side. Although there were some variations in TUNEL staining during segmentation and pharyngeal stages, TUNEL staining continued to be localized to the central nervous system, and was also detected in the sensory organs, trigeminal ganglions, and the primary sensory neurons. High levels of the cell death in developing brain between 20-somite and prim-6 stages are thought to play a role in the morphogenesis and organization of the brain. At prim-16 stage, cell death is considerably reduced in the brain region. Dying cells are mainly localized to the prospective brain region where ectodermal cells are about to initiate neurogenesis. As development progressed, high levels and more reproducible patterns of cell death were observed in the developing nervous system. Intensive TUNEL staining was restricted to the trigeminal ganglions, the primary sensory neurons, and sensory organs, such as olfactory pits and otic vesicles. Thus, PCD patterning in zebrafish embryos occurs randomly at early stages and becomes restricted to certain region of the embryos. The spatio-temporal pattern of PCD during the early embryonic development in zebrafish will provide basic information for further studies to elucidate genes involved in. regulation of PCD largely unknown in vivo during vertebrate embryogenesis.
