OBJECTIVE: To observe the effects of antagonistic needling therapy on lower limb spasticity and the muscle morphology of the tibialis anterior and gastrocnemius in patients with stroke. METHODS: A total of 100 patients with post-stroke lower limb spasticity were randomly divided into an antagonistic needling group (50 cases, 1 case dropped out) and a routine acupuncture group (50 cases, 1 case dropped out). Both groups received basic treatment and rehabilitation training. The routine acupuncture group was treated with scalp acupuncture at anterior oblique line of vertex-temporal and vertex lateral line 1, combined with body acupuncture at Jianyu (LI15), Hegu (LI4), Zusanli (ST36), Taichong (LR3), etc. on the affected side, with Quchi (LI11) and Hegu (LI4), Zusanli (ST36) and Fenglong (ST40), Yanglingquan (GB34) and Taichong (LR3) connected to an electroacupuncture device, using disperse wave at 2 Hz of frequency. The antagonistic needling group used the same scalp and upper limb acupoints as the routine acupuncture group, with additional antagonistic needling on the lower limb at Yanglingquan (GB34), Qiuxu (GB40), Jiexi (ST41), and Xuanzhong (GB39) on the affected side, with Quchi (LI11) and Hegu (LI4), Yanglingquan (GB34) and Qiuxu (GB40), Jiexi (ST41), and Xuanzhong (GB39) connected to an electroacupuncture device, using disperse wave at 2 Hz of frequency. Both groups received treatment once daily for 6 consecutive days per course, with a total of 4 courses. The modified Ashworth scale (MAS), Holden functional ambulation classification (FAC), lower limb Fugl-Meyer assessment (FMA), composite spasticity scale (CSS), and musculoskeletal ultrasound parameters (thickness and fiber length of the tibialis anterior and gastrocnemius, and pennation angle of the gastrocnemius on both sides) were evaluated before and after treatment. Clinical efficacy was compared between the two groups. RESULTS: Compared before treatment, the MAS grades and CSS scores were decreased in both groups after treatment (P<0.01), with greater reductions in the antagonistic needling group (P<0.05, P<0.01). FAC grades and FMA scores were increased in both groups after treatment (P<0.01, P<0.05), with greater improvements in the antagonistic needling group (P<0.05). The muscle thickness, fiber length of the tibialis anterior, the muscle thickness, fiber length and pennation angle of the gastrocnemius on the affected side were improved in both groups after treatment (P<0.01), with greater improvements in the antagonistic needling group (P<0.01, P<0.05). On the unaffected side, these parameters were also increased after treatment in both groups (P<0.01, P<0.05), but the antagonistic needling group showed smaller increases than the routine acupuncture group (P<0.01, P<0.05). The total effective rate in the antagonistic needling group was 91.8% (45/49), higher than 81.6% (40/49) in the routine acupuncture group (P<0.05). CONCLUSION Antagonistic needling could effectively reduce spasticity, improve motor function, and enhance muscle structure in patients with post-stroke lower limb spasticity.

Lymphedema, a chronic disease that lowers patients' quality of life, is categorized as primary or secondary. Secondary lymphedema can be improved by treating the underlying cause. However, in many cases, efforts are not made to identify the primary cause of lymphedema and treatment is targeted at the edema itself, resulting in misdiagnosis. Here, we describe the case of a 61-year-old man with right leg edema of unknown cause that had persisted for 3 years. Intestinal tuberculosis was confirmed during a re-evaluation of the cause, and his symptoms improved after anti-tuberculous treatment. This improvement was assessed qualitatively by indocyanine green lymphography before and after treatment, as well as by observation of the clinical symptoms. Lower extremity lymphedema caused by intestinal tuberculosis is extremely rare, and this case reveals the importance of continuing to identify the causes of resistant pathologies.

Objective To summarize the characteristics of cases of electrocution due to direct current （DC） electronic hunter, and to provide references for forensic identification. Methods Four cases of electrocution due to DC electronic hunter were collected. Statistical analysis was carried out from the perspective of the scene and electric marks distribution, damage characteristics and histopathological changes. Results All the 4 cases of electrocution were accidental events. There were multiple electric marks, most of which were located in the lower limbs with serious damage. Some strip type electric marks were visible. Conclusion The distribution, morphological characteristics and severity of the electric marks caused by DC electronic hunter are different from those of the ordinary low-voltage alternating current damage. It is alerting that there would be actions of destroying the scene and abandoning the corpse in such cases.

Athletic injuries of the lower extremities are commonly encountered in clinical practice. While some pathology can be diagnosed on physical exam, others are a clinical dilemma with nonspecific symptomatology. In these situations, ultrasound imaging can be utilized as an exceptional diagnostic tool, offering unique advantages over other imaging modalities. This article will review the imaging characteristics of commonly encountered athletic injuries of the lower extremity.

PURPOSE: The aim of this study was to analyze anatomical popliteal artery entrapment syndrome (PAES) and to individualize the treatment of this condition according to the anatomical status of the artery and the adjacent structure. METHODS: A total of 35 anatomical PAES legs in 23 consecutive patients treated within the Asan Medical Center, Seoul, Korea between 1995 and 2011 were analyzed retrospectively. Anatomical PAES was diagnosed by MRI and/or CT scans of the knee joint, and CT or conventional transfemoral arteriography of the lower extremities. RESULTS: We noted a type II gastrocnemius medial head (GNM) anomaly, a type III GNM anomaly, or an aberrant plantaris muscle in 51.4%, 20%, and 28.6% of PAES legs, respectively. In assessments of the arterial lesions, popliteal or tibial artery occlusion was noted in 19 of 26 symptomatic PAES legs. For cases without popliteal artery lesions, myotomy of the anatomically deranged muscle was performed in 5 of 7 symptomatic and 4 of 9 asymptomatic PAES legs. For occluded popliteal arteries, we performed ten direct repairs of the pathological popliteal artery and 4 femoro-below the knee popliteal bypass surgeries. As a result of the arterial Surgery, 9 direct procedures with myotomy yielded a patent artery, while 3 graft failures were noted in the bypass group. The median follow-up period was 84 months (range, 12–206 months). CONCLUSION: We recommend that treatment of PAES should be individualized based on pathology, symptoms, and various imaging studies.

OBJECTIVES: To test whether myocardial apoptosis can be induced by traumatic fracture of lower limbs with hemorrhage, in order to lay a foundation of myocardial injury after traumatic fracture for the follow-up study. METHODS: Twenty SD rats were randomly divided into two groups, i. e. control group and trauma group(=10). A rat model of traumatic hemorrhage was establish, and a traumatic model of the original generation of myocardial cell culture was constructed . The level of interleukin-2(IL-2),IL-6,IL-10 and tumor necrosis factor-α(TNF-α) in rat serum was detected by ELISA at 0, 1, 2, 4, 8, 12, 16, 24 and 48 hour to find the most significant point. The pathological cardiac injury in rats was observed by HE staining under a microscope, and the apoptosis of cultured cardiomyocyte was detected by TUNEL methods. The expressions of apoptosis gene,(Bcl-2) and Bax, in myocardium of rat and cultured cardiomyocyte were detected by Western blot and RT-PCR. RESULTS: At the 4 hour after trauma, IL-6 and IL-10 in the serum of rats reached its highest, IL-2 reached its lowest at the 8th hour after trauma, and TNF-αreached its highest at 1 hour after trauma, then all recovered to their normol level gradually. Myocardial HE staining indicated that cardiomyocyte was swelling, disordered derangement, inflammatory cell infiltrated; a large number of myocardial cell nuclei was dyedbrown in TUNEL test which proved that the apoptosis index increased (<0.05). Western blot and RT-PCR results showed that the expression of pro-apoptotic gene Bax was up-regulated (<0. 05), while expression of anti apoptosis gene Bcl-2 down-regulated (<0.05). CONCLUSIONS The myocardial apoptosis can be induced by traumatic fracture of lower limbs with hemorrhage in rats, and then lead to myocardial injury.

Syringomyelia is a disorder in which a cavity has formed within the spinal cord. Idiopathic syringomyelia is not associated with identifiable causes such as Chari type 1 malformation, spinal cord tumor, vascular malformation, tethered cord, arachnoiditis, hydrocephalus, or previous spinal surgery. The main neurologic symptoms of idiopathic syringomyelia are toe-walking, constipation, incontinence, abnormal reflexes, and lower extremity weakness. Patients may present with various symptoms such as scoliosis, cutaneous markers, pain in the lower extremities or back, or may be asymptomatic. Herein, we report a young child with idiopathic syringomyelia presenting with subtle neck pain. A 23-month-old boy visited the neurologic clinic after 3 months of right occipital area neck pain. He had no history of trauma or central nervous system infection, and neurologic examination results were normal except for right posterior neck hyperesthesia. Brain and spinal magnetic resonance imaging showed an ovoid intramedullary cystic lesion (9.7×5.0×4.7 mm) at C6/7 of the spinal cord. There was no evidence of Chiari malformation or other lesions that can be primary pathologies of syringomyelia. Electromyogram/nerve conduction velocity results were normal. The subject was diagnosed as idiopathic syringomyelia. His symptoms and neurologic/radiologic indications showed no change at a 1-year follow-up. Idiopathic syringomyelia symptoms are varied and may be overlooked by physicians. Pediatricians may consider syringomyelia if patients complain about persistent sensory abnormality. All patients who present with syringomyelia should undergo detailed neuroimaging of the entire neuraxis to elucidate the proximate cause of the lesion.

PURPOSE: Soft tissue hemangioendothelioma (STHE) is a rare vascular tumor, which has a similar prognosis to borderline malignancy. The disease is poorly understood in pediatric cases because of its low incidence; therefore, we investigated treatment strategies for STHE in children. METHODS: We retrospectively analyzed 8 patients with STHE, who were pathologically confirmed between January 1995 and June 2015. The median duration of follow-up was 72 months. RESULTS: Five were male and the median age at the time of surgery was 1.2 years. Six patients presented with a palpable mass, and 2 patients experienced facial paralysis. The median tumor size was 4.0 cm. The following tumor locations were observed head (2 patients), neck (2 patients), chest wall (1 patient), sacrococcyx (1 patient), upper limb (1 patient), and lower limb (1 patient). The patients underwent either microscopic complete resection (R0) (3 patients), macroscopic complete resection (R1) (2 patients), or macroscopic incomplete resection (R2) (3 patients). After histopathological examination, 6 patients were diagnosed with kaposiform hemangioendothelioma (HE), one with retiform HE, and one with epithelioid HE. Postoperative sequelae occurred as gait disturbance, hearing impairment, and vocal cord palsy. Tumor recurrence or regrowth occurred in 4 patients. These patients underwent reoperation and IFN therapy; however, in the patient with epithelioid HE, metastasis to the scalp occurred after these therapies. The patient with the head tumor who underwent R2 resection, underwent resection three more times, but died 11 months after the first surgery. CONCLUSION: When treating STHE in children, R0 resection should be first considered, but recurrence and metastasis should be monitored depending on the size, pathology, and location of the lesion. When major sequelae are expected, function-preserving surgery could be considered, depending on tumor location, size, and nearby organs.

OBJECTIVE: Sensory symptoms are common in patients with Parkinson disease (PD), although its exact prevalence and causes are not well known. We aimed to investigate whether peripheral pathology contribute to chronic sensory symptoms in patients with PD by nerve conduction test. METHODS: We recruited consecutively 34 patients with clinically probable PD (Hoehn-Yahr stage, 1–3) who developed persistent sensory symptoms in their lower extremities during optimal dopamine replacement therapy. Twenty-five patients who are above age of 70 or have other possible causes of neuropathy as determined by laboratory testing or medical record were excluded. Age- and gender-matched PD patients with same disease severity who have never developed sensory symptom during the same period were allocated to paired controls. Total 18 subjects participated in this study. Nerve conduction tests on peroneal motor nerve and sural sensory nerve were performed in all subjects. Amplitude and conduction velocity were compared between the paired subjects using Wilcoxon signed rank test. RESULTS: Subjective sensory symptoms of the 9 patients were variable: pain (4/9), chilling (3/9), burning (1/9), and tingling sense (1/9). There were no significant difference of mean values of compound muscle action potential/sensory nerve action potential amplitude and conduction velocity between patients and their paired controls. CONCLUSION: This study supports the hypothesis that the origin of chronic sensory symptoms in PD patients is more central than peripheral.
