Cognitive impairment in children with benign childhood epilepsy with centrotemporal spikes and attention deficit hyperactivity disorder: a prospective study / 中国当代儿科杂志

OBJECTIVES@#To study the difference in cognitive impairment between the children with benign childhood epilepsy with centrotemporal spikes (BECT) and attention deficit hyperactivity disorder (ADHD) and those with BECT or ADHD alone.@*METHODS@#A prospective study was performed on 80 children with BECT and ADHD, 91 children with BECT, and 70 children with ADHD , who were diagnosed with the diseases for the first time. Seventy children of the same age who underwent physical examination were enrolled as the healthy control group. Event-related potential P300, Wechsler Intelligence Scale for Children, and integrated visual and auditory continuous performance test were used to measure and compare each index between groups.@*RESULTS@#Compared with the healthy control group, the BECT+ADHD group, the BECT group, and the ADHD group had a significantly prolonged P300 latency, a significant reduction in the amplitude of P300, and significant reductions in the scores of verbal comprehension index (VCI), perceptual reasoning index (PRI), working memory index (WMI), processing speed index (PSI), full scale intelligence quotient (FSIQ), auditory response control quotient (ARCQ), visual response control quotient, full response control quotient (FRCQ), auditory attention quotient (AAQ), visual attention quotient, and full attention quotient (@*CONCLUSIONS@#Compared with the children with BECT or ADHD alone, the children with both BECT and ADHD have basically the same fields of cognitive impairment but a higher degree of cognitive impairment in some fields.

Open reduction and mini-plate internal fixation for the treatment of fracture and dislocation of coccyx / 中国骨伤

<p><b>OBJECTIVE</b>To explore the therapeutic methods of fracture and dislocation of coccyx and evaluate its curative effects.</p><p><b>METHODS</b>From May 2002 to March 2010,56 patients with fracture and dislocation of coccyx were divided into surgical treatment group and non-surgical treatment group. There were 7 males and 20 females in surgical treatment group with an average age of (48.1 +/- 0.6) years (ranged, 29 to 62 years), treated with open reduction and mini-plate internal fixation. There were 8 males and 21 females in non-surgical treatment group with an average age of (47.5 +/- 0.9) years (ranged, 19 to 54 years),treated with manipulative reduction. All patients were underwent X-ray examination and were finally diagnosed before treatment. Clinical symptoms and Visual Analogue Scales (VAS) of all patients were statistically analyzed before and after treatment.</p><p><b>RESULTS</b>There was no significant difference between two groups in gender, age, BMI index and VAS evaluation. All patients were followed up from 12 to 25 months with an average of 17.2 months. In surgical treatment group,there were 26 cases with I/a incision and 1 case with II/a incision; the excellent rate of clinical symptom was respectively 92.6% and 100% at leaving hospital and final follow-up; the improvement rate of VAS was 97.6% and was excellent result;internal fixtures were removed at the 1 to 2 years after treatment and no unwell symptoms occurred; VAS of all patients in the group was 0 point. In non-surgical treatment group,the excellent rate of clinical symptom was respectively 72.4% and 82.8% at leaving hospital and final follow-up; the improvement rate of VAS was 72.1% and was good result. There was significant difference in clinical results between two groups (P<0.05).</p><p><b>CONCLUSION</b>The results indicated that fracture and dislocation of coccyx should be treated in time. For the treatment of patients with manipulative reduction failures, instability reduction by X-ray examination and serious rectal irritation, open reduction and mini-plate internal fixation can obtain satisfactory results.</p>

Efficacy evaluation for the treatment of unstable lumbar disc herniation by traditional and modified lamina osteotomy replantation / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The traditional lamina osteotomy replantation method is prone to nerve root injury and low back pain recurrence. Our team has proposed a modified approach that improves the osteotomy site and its fixation procedure. The aim of this study was to evaluate the clinical efficacy of traditional and modified lamina replantation methods in treating unstable lumbar disc herniation.</p><p><b>METHODS</b>From March 2008 to August 2011, 124 patients with unstable lumbar disc herniation were enrolled and randomly divided into the following two groups according to random digital table: group A (traditional group) consisting of 61 patients who underwent traditional laminectomy replantation, and group B (modified group) consisting of 63 patients who underwent modified lamina replantation. Both surgeries were performed by the same surgeons. The two groups had no significant difference in gender, age, symptoms, time of onset and the prominent segment. Visual analogue scale (VAS), Oswertry disability index (ODI), and Japanese Orthopaedic Association (JOA) scores, operative time, blood loss, complication rate, radiographic healing rates, and low back pain recurrence rates were compared between the two groups.</p><p><b>RESULTS</b>There were 121 patients followed up for more than one year, and the follow-up rate was 97.6%. Nerve injury occurred in two patients (3.3%) in the modified group and 12 patients (20.0%) in the traditional group. Dural injury occurred in one patient (1.6%) in the modified group and seven patients (11.7%) in the traditional group. Pseudarthrosis occurred in two patients in the modified group and in 18 patients in the traditional group with 1-year fusion rates of 96.7% and 70.0%, respectively. Recurrence of lower back pain after one year was noted in three patients (4.9%) in the modified group, and in 15 (25.0%) in the traditional group. Leg pain recurrence was noted in one patient (1.6%) in the modified group and in three cases (5.0%) in the traditional group. The one-year healing rates of nerve injury, dural injury, replantation lamina and low back pain recurrence rates after one year were significantly different (P < 0.05) between the two groups. At two weeks, three months, six months and one year postoperatively, both groups had significant improvement in VAS, ODI, and JOA scores from their preoperative values (P < 0.05). No significant difference was detected between the short term postoperative scores between groups A and B (P > 0.05). However, a significant difference was found one year later (P < 0.05).</p><p><b>CONCLUSIONS</b>Compared to the traditional approach, the modified technique for lamina replantation showed lower rates of dural and nerve damage, a higher lamina healing rate, a lower back pain recurrence rate, and better clinical scores. It is a safe and effective operation for lumbar spine surgery.</p>

Observation on therapeutic effect of catgut implantation at acupoints on exercise fatigue and study on the mechanism / 中国针灸

<p><b>OBJECTIVE</b>To probe into the therapeutic effect of catgut implantation at acupoint on exercise fatigue and to study on the mechanism.</p><p><b>METHODS</b>Catgut implantation was given at main points Guanyuan (CV 4), Shen shu (BL 23), Mingmen (GV 4), Zusanli (ST 36), Sanyinjiao (SP 6) in 41 players during training for 2 courses. Training-related condition and changes of blood testosterone (T) and hemoglobin (Hb) before and after training were observed.</p><p><b>RESULTS</b>After treatment, sleeping quality, the mental state at the time of getting out of bed in the morning, appetite, training wish, training stamina, training quality, training attention, etc. in the player significantly improved, and blood T and Hb levels significantly increased.</p><p><b>CONCLUSION</b>Catgut implantation at acupoints can significantly improve exercise fatigue in the player and the mechanism is possibly related with increase of testosterone and hemoglobin levels.</p>
