ABSTRACT
A 51-year-old male who is right-handed visited the outpatient for right fingers-drop. The patient's fingers, including thumb, were not extended on metacarpophalangeal joint. The active motion of the right wrist was available. The electromyography and nerve conduction velocity study were consistent with the posterior interosseous neuropathy. Further evaluation was done with the magnetic resonance imaging for finding the space-occupying lesion or any possible soft tissue lesion around the radial nerve pathway. On magnetic resonance imaging, the ganglion cyst, which was about 1.8 cm in diameter, was observed on the proximal part of the superficial layer of the supinator muscle (Arcade of Frohse). The surgical excision was done on the base of ganglion cyst at the base of stalk of cyst which looked to be connected with proximal radioulnar joint capsule. The palsy had completely resolved when the patient was observed on the outpatient department a month after the operation.

Objective To observe variation of Caveolin-1 expression in dorsal root ganglia and spinal dorsal horn in chronic neuropathic pain of rats.Methods Experimental animals of 56 SD rats were used for this study,and 28 rats for control.They were divided into 7 groups and their L5 nerves were ligated to produce the neuropathic pain model.After 1,3,5,7,10,14,21d of surgery,the mechanical shrinkage foot threshold and hot shrinkage foot incubation period were detected.Neuropathic pain models were confirmed to make successfully compared with the control group.Rats in the surgery group and the control group rats were all put to death on the 22d.The total protein of L5 spinal cord and dorsal root ganglia was extracted from the same side or the opposite side.The Caveolin-1 expression of different groups and sides was detected by the Western blot method in dorsal root ganglia and spinal dorsal horn in chronic neuropathic pain of rats.Results After 5,7,10,14,21d of L5 ligation,the expressions of Caveolin-1 were increased by 40.4％ ± 3.67％,126.9％ ± 5.46％,159.7％ ±4.89％,119.1％ ±5.77％ and 91.4％ ±5.31％ in the same sides.The difference was significant on 10d(P ＜0.01)after the surgery.After 5d,7 d,10d,14d,21 d of L5 ligation,the expressions of Caveolin-1 were increased by 33.3％ ± 4.89％,152.8％ ±3.56％,142.1％ ±5.43％,103.2％ ± 6.21％,175.6％ ±4.81％ in the opposite sides.It had statistic difference on 10d,14d,21d (P ＜ 0.05).There were no statistic differences among control groups.Conclusion The Neuropathic chronic pain can increase the Caveolin-1 expressions on the same side of dorsal root ganglia and spinal dorsal horn.
ABSTRACT
Objective Application of near-infrared fluorescent thoracoscope in visualizing thoracic sympathetic ganglions,to explore the effectiveness and safety of the technique.Methods Patients received near-infrared fluorescent thoracoscopic surgery was continuously in rolled from September 2015 to September 2016.The patient was infused indocyanine green 5 mg intravenous 24 hours before surgery.The thoracic sympathetic ganglions were observed under white and fluorescence model during surgery.The videos and photos were analyzed and the relationship between sympathetic ganglions and ribs was recorded.Results 31 patients was in rolled,including 12 males and 19 females.The average age was 47 years.The sympathetic ganglion of each patient was well visualized under fluorescence model.The signal to background ratio was 1.67.As we found that 48.8％ ganglions located in the upper edge of lower rib.Besides,26.9％ of T2 ganglions and 23.1％ of T3 ganglions located on the rib.Conclusion Near-infrared fluorescent thoracoscope was effiective and safety to visualize the thoracic sympathetic ganglions.The sympathectomy of palmar hyperhidrosis could be done by near-infrared fluorescent thoracoscope more precisely.
ABSTRACT
Objective To explore the characteristics of diffusion weighted imaging (DWI) of lumbar sacral nerve roots (LSNR)in normal and degenerative lumbosacral vertebrae. Methods The research recruited 20 normal volunteers and 31 patients with spinal stenosis on conventional MRI and DWI scans in lumbosacral spine. We measured the areas from lumbar 3 to sacral 1 at the intervertebral spaces and reconstructed the 3D maximum intensity projection (MIP) and counted the apparent diffusion coefficient (ADC)of LSNR and ganglions. Results In the control group, 196 (98%) LSNR ran symmetrically and lateroinferiorly and 200 ganglions were well defined on MIP of DWI. In the patients group, 74 LSNR showed changes of compression on both T1WI and T2WI, in which DWI appeared thin and distorted in 59 (80%). The ADC value of LSNR were(1.70 ± 0.40)× 10-3 mm2/s and(1.98 ± 0.57) × 10-3 mm2/s separately in normal volunteers and patients (P=0.000), while the ADC values of ganglions were(1.42 ± 0.21)× 10-3 mm2/s and (1.54 ± 0.53)× 10-3 mm2/s respectively in normal volunteers and patients (P=0.000). Conclusion DWI can display the pattern and course of LSNR and ganglions, which indicate that ADC values of compressed LSNR and ganglions are higher than normal ones.
ABSTRACT
Ganglion cyst is the most common benign tumor arising from the hand and wrist. Rarely, they are found within the tendon. To date, only 10 cases in English papers and 7 cases in domestic papers on ganglion cysts in extensor digitorum tendons have been reported. Due to the rarity of this entity, it is difficult to suspect intratendinous ganglion fully based on the physical examination. Accordingly, preoperative studies such as ultrasonography, magnetic resonance imaging are recommended when suspicious result is revealed on the physical examination. Treatment should include en bloc resection of the affected tendon to reduce recurrence. But functional loss always has to be considered. This study reports two cases of intratendinous ganglion cysts that arised from the second and fourth extensor digitorum tendon.

El ganglión intraóseo del carpo es una de las causas de dolor de la muñeca, aunque se diagnostica infrecuentemente y en ocasiones es un hallazgo casual. Se presenta el caso clínico de una paciente de 55 años de edad, raza mestiza, que acudió a consulta por un cuadro clínico doloroso de la muñeca, sin antecedentes traumáticos y de aparición espontánea, con 3 meses de evolución. El diagnóstico inicial fue una sinovitis de la muñeca y la paciente no mejoró con los diferentes tratamientos aplicados. Después de varios estudios se llegó a la conclusión de que la paciente tenía un ganglión intraóseo del carpo. Esta lesión respondió bien al procedimiento quirúrgico, que consistió en legrado e injerto con hidroxiapatita porosa coralina® HAP-200, con lo que se logró evitar el potencial riesgo de colapso óseo y no hubo recidivas
Carpal intraosseous ganglion is one of the wrist pain cause although is infrequently diagnosed and in occasions it is a casual finding This is the case of black patient aged 35 came to consultation due to a painful clinical picture in wrist without traumatic backgrounds and a spontaneous appearance with three of evolution. Initially was diagnosed with a wrist synovitis and without improvement with the different treatments applied. After some studies we concluded that patient had a carpal intraosseous ganglion. This lesion responded well to surgical procedure which consisted of curettage and graft with HAP-200 coralline and porous hydroxyapatite® avoiding the potential risk of bone collapse without relapses
L'une des causes de la douleur du poignet est le ganglion intra-osseux du carpe, quoique son diagnostic soit rare, et souvent casuel. Le cas clinique d'une patiente âgée de 55 ans, métisse, assistant en consultation en raison d'une douleur du poignet de 3 mois de durée, sans antécédents traumatiques ni apparition spontanée, est présenté. Le diagnostic initial a été une synovite du poignet, et les différents traitements appliqués n'ont pas guéri la patiente. Après plusieurs épreuves on a conclu que la patiente était atteinte d'un ganglion intra-osseux du carpe. Cette anomalie a bien répondu à la chirurgie, consistant à un curetage et à un greffon à hydroxyapatite poreuse corallienne HAP-200®, laquelle a évité le risque potentiel de collapse osseux et de récidives
ABSTRACT
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.
