Objective To evaluate the long-term effectiveness of treating early-middle stage avascular necrosis of the femoral head (ANFH) with core decompression and bone grafting. Methods Between January 2000 and December 2006, 87 ANFH patients (114 hips) were treated with core decompression and bone grafting, including 54 cases (62.1%) of alcohol-induced ANFH, 26 cases (29.9%) of steroid-induced ANFH, and 7 cases (8.0%) of idiopathic ANFH. There were 74 males (97 hips) and 13 females (17 hips), aged 20-56 years (mean, 38 years). The disease duration was 3-46 months (mean, 18 months). According to Ficat staging, 16 hips were at stage I, 68 hips at stage II, and 30 hips at stage III. The Harris score and Ficat stage were compared between pre- and post-operation to assess the outcomes clinically and radiologically. The hip survival was analyzed by the Kaplan-Meier method. Results Eighty-seven patients were followed up 5 years to 11 years and 10 months (mean, 8 years and 9 months). The Harris hip score was significantly increased from 73.13 ± 7.17 at preoperation to 81.59 ± 13.23 at postoperation (t= — 9.318, P=0.000). The clinical success rate was 69.3% (79/114) and the radiological success rate was 54.4% (62/114). Kaplan-Meier survival analysis showed that the overall survival rate was 84.2% (96/114); the survival rates of Ficat stage I [100% (16/16)] and stage II [91.2% (62/68)] were higher than that of stage III [60.0%(18/30)] (P lt; 0.01); there was no significant difference between Ficat stage I and II (χ2=1.520, P=0.218). Conclusion Core decompression with bone grafting is a safe and effective procedure for the treatment of Ficat stages I-II (early stage) ANFH, and the long-term effectiveness is satisfactory. But the long-term effectiveness is unsatisfactory for the patients at the Ficat stage III (middle stage).
ObjectiveTo investigate the long-term efficacy and the influencing factors of thymectomy for thymoma patients associated with myasthenia gravis. MethodsWe retrospectively analyzed the clinical and follow-up data of 126 thymoma patients associated with myasthenia gravis underwent extended thymectomy from June 2002 to December 2015 in our hospital. There were 26 males and 37 females at the mean age of 54.51±12.62 years. We built up survival analysis model to analyze the effect of those following factors on postoperative result:sex, the age when operated, the preoperative course of disease, the condition of associating with other diseases, history of critical illness, steroid administration time before operation, Osserman classification, Masaoka staging, WHO pathological type, surgical approach, tumor size and so on. Result The average follow-up time was 35(5-96) months. During follow-up period, 12 patients (19%) achieved complete remission, 39 patients (62%) achieved partial remission, 7 patients (11%) kept stable, 5 patients (8%) deteriorated and the total effective rate was 81%. The result of log-rank analysis showed that the preoperative course of disease (P=0.027), history of critical illness on myasthenia gravis (P=0.035) and Osserman classification (P=0.018) were related to incomplete remission, whlie the result of Cox regression analysis showed that the preoperative course of disease (P=0.001) and Osserman classification (P=0.012) were the independent risk factors for incomplete remission. ConclusionExtended thymectomy is an effective treatment for thymoma patients associated with myasthenia gravis, but the symptom of those patients whose preoperative course of disease are more than 12 months or Osserman classification is at ⅡB, Ⅲ and Ⅳ type of Osserman classification have poor effect after operation.
PurposeTo analyze the effect of medication withdraw (MW) on long-term electroencephalogram (EEG) monitoring in children who need preoperative assessment for refractory epilepsy.MethodsRetrospective analysis was performed on the data of preoperative long-term EEG monitoring of children with refractory epilepsy who needed preoperative evaluation in the Pediatric Epilepsy Center of Peking University First Hospital from August 2018 to December 2019. Monitoring duration: at least three habitual seizures were detected, or the monitoring duration were as long as 10 days. MW protocol was according to the established plan.ResultsA total of 576 children (median age 4.4 years) required presurgical ictal EEGs, and 75 (75/576, 13.0%) needed MW for ictal EEGs. Among the 75 cases, 38 were male and 37 were female. The age range was from 15 months to 17 years (median age: 7.0 years). EEG and clinical data of with 65 children who strictly obey the MW protocol were analyzed. The total monitoring duration range was from 44.1 h (about 2 days) to 241.8 h (about 10 days)(median: 118.9 h (about 5 days)). Interictal EEG features before MW were including focal interictal epileptiform discharge (IED) in 39 cases (39/65, 60%), focal and generalized IED in 2 cases (2/65, 3.1%), multifocal IED in 20 cases (20/65, 30.7%), multifocal and generalized IED in 2 cases (2/65, 3.1%), and no IED in 2 cases (2/65, 3.1%). After MW, 18 cases (18/65, 27.7%) had no change in IED and the other 47 cases had changes of IED after MW. And IEDs in 46 cases (46/65, 70.8%) were aggravated, and IED was decreased in 1 case. The pattern of aggravated IED was original IED increasement, in 41 cases (41/46, 89.1%), and 5 cases (5 /46, 10.9%) had generalized IED which was not detected before MW. Of the 46 patients with IED exacerbations, 87.3% appeared within 3 days after MW. Habitual seizures were detected in 56 cases (86.2%, 56/65) after MW, and within 3 days of MW in 80.4% cases. Eight patients (14.3%) had secondary bilateral-tonic seizure (BTCS), of which only 1 patient had no BTCS in his habitual seizures. In 56 cases, 94.6% (53/56) had seizures after MW of two kinds of AEDs.Conclusions① In this group, thirteen percent children with intractable epilepsy needed MW to obtain ictal EEG; ② Most of them (86.2%) could obtain ictal EEG by MW. The IED and ictal EEG after MW were still helpful for localization of epileptogenic zone; ③ Most of the patients can obtain ictal EEG within 3 days after MW or after MW of two kinds of AEDs;4. The new secondary generalization was extremely rare.
Objective To guide blood glucose management during pregnancy and reduce the incidence of long-term complications of the fetus by exploring the long-term growth condition of offspring of pregnant women with gestational diabetes mellitus. Methods A total of 180 cases full-term newborns of pregnant women with gestational diabetes mellitus from December 25th, 2011 to December 25th, 2012 were selected as the diabetes group. Another 200 newborns of pregnant women without any complications were randomly collected as the control group. Birth weight, gestational age, sex, blood glucose, and 24-, 48-, 72- and 120-hour transcutaneous bilirubin value after the birth of the newborns were recorded; weight, height, body mass index (BMI), triglycerides, total cholesterol, high density lipoprotein (HDL), low density lipoprotein, blood pressure and fasting plasma glucose quota between the two groups were contrasted when the children were three years old. Results There were no significant difference in the birth weight, gestational age and sex between the diabetic and the control group. The blood glucose levels of the newborns in the diabetic group was significantly lower than that in the control group (P<0.05). The 24-, 48-, 72- and 120-hour transcutaneous bilirubin values of the newborns in the diabetic group were significantly higher than those of the control group (P<0.05). The weight, height and BMI of the three years old offspring in the diabetic group were significantly higher than those in the control group (P<0.05). There were no significant difference in triglycerides, total cholesterol, HDL, Low density lipoprotein, fasting plasma glucose quota, and systolic blood pressure between the diabetic group and the control group (P>0.05), but the diastolic blood pressure in the diabetic group was much higher than that in the control group (P<0.05). Conclusion The impact of gestational diabetes mellitus on offspring of pregnant women was not only in the fetus and newborn period, but also in the future, which should be timely intervened.
Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. It is characterized by an interventricular communication with an overriding aorta, subpulmonary obstruction, and consequent right ventricular hypertrophy. The potential for late complications is an important concern for growing number of survivors after surgical repair, although long-term survival rates are excellent. Progressive pulmonary valve regurgitation leading to right heart failure and arrhythmias are common late complications and major reasons of mortality. In this review, we focus on research progress of pathogenesis and treatment of late complications after TOF repair, and the importance of long-term follow-up is emphasized.
ObjectiveTo investigate influence factor of long-term survival of primary colorectal signet-ring cell carcinoma. MethodThe clinical data of 37 patients with primary colorectal signet-ring cell carcinoma from January 1990 to November 2010 in this hospital were analyzed retrospectively. ResultsThe cumulative survival rates of 1-, 2-, 3and 5-year after the initial surgery were 70.3%, 51.4%, 27.0%, and 10.8% respectively. The survival time of 37 patients was 26 months. The results of univariate analysis showed that the TNM stage, T stage, preoperative intestinal obstruction or not, operation mode, and postoperative chemotherapy or not were associated with the survival time of primary colorectal signet-ring cell carcinoma (P < 0.05). The results of multivariable analysis showed that TNM stage, T stage, and preoperative intestinal obstruction or not were the independent factors for the prognosis of patients with primary colorectal signetring cell carcinoma. ConclusionsThe survival rate of patients with primary colorectal signet-ring cell carcinoma is lower. TNM stage, T stage, and preoperative intestinal obstruction or not are independent factors of it. Chemotherapy after operation could prolong survival time of patients with primary colorectal signet-ring cell carcinoma.
ObjectiveTo study the long-term prevention effect of self-developed chitosan electrospun membrane on cerebrospinal fluid leakage. MethodsTwenty-five healthy adult New Zealand rabbits were selected to prepare the bilateral dural defect (0.8 cm×0.8 cm in size) via midline incision of head.Defect of the right was repaired with chitosan electrospun membrane as the experimental group; defect of the left was not repaired as the control group.At 2-16 weeks after operation,one rabbit was sacrificed for the general observation of inflammatory response surrounding bone window and absorption of chitosan electrospun membrane; at 3 and 6 weeks after operation,5 rabbits were sacrificed for sampling to observe histological change and collagen expression by HE and Masson staining,and to measure the expressions of epidermal growth factor receptor (EGFR) and basic fibroblast growth factor (bFGF) by immunohistochemical staining. ResultsNo inflammatory reaction of swelling,exudation,and sppuration appeared in the skin and subcutaneous tissue after operation in 2 groups.There was no adhesion around the chitosan electrospun membrane,and new fiber membrane formed under the chitosan electrospun membrane in the experimental group; no cerebrospinal fluid leakage happened; the chitosan electrospun membrane was gradually degraded with time,and was completely absorbed at 16 weeks.There was uneven scar around the dural detect in control group.Histological observation showed less inflammatory cell infiltration in the experimental group,showing significant difference in the number of inflammatory cells compared with control group at 3,6 weeks (P<0.05); capillary,granulation tissue and collagen fiber massively proliferated; collagen fiber arranged in line,and there was a clear borderline between chitosan electrospun membrane and adjacent collagen fiber.The immunohistochemical staining showed that there were high expressions of bFGF and EGFR in the experimental group,and low expressions of bFGF and EGFR in the control group. ConclusionChitosan electrospun membrane for dural defect of rabbit can effectively reconstruct the dura,and it has exact long-term prevention effect on cerebrospinal fluid leakage.
Objective To retrospectively analyze the long-term effectiveness of percutaneous laser disc decompression (PLDD) in treatment of cervical spondylosis. Methods Between March 2003 and June 2005, 156 patients with cervical spondylosis were treated with PLDD. There were 74 males and 82 females with an average age of 55.4 years (range, 31-74 years). The disease duration varied from 2 months to 15 years. Fifty-nine patients were classified as cervical spondyloticradiculopathy, 48 as vertebral-artery-type cervical spondylosis, 19 as cervical spondylotic myelopathy, and 30 as mixed type spondylosis. The lesions were located at the levels of C3,4 in 32 discs, C4,5 in 66 discs, C5,6 in 89 discs, and C6,7 in 69 discs, and including 71 one-leve lesion and 85 multi-level lesions. All cases were followed up to study the long-term effectiveness and correlative factors. Results A total of 117 (75%) patients’ symptoms were l ightened or eased up immediately after operation. Discitis occurred in 1 case at 3 days after operation and was cured after 3 weeks of antibiotic use. All patients were followed up 5 years to 7 years and 3 months (5 years and 6 months on average). According to Macnab criteria, the long-term effectiveness was excellent in 60 cases (38.46%), good in 65 cases (41.67%), fair in 19 cases (12.18%), and poor in 12 cases (7.69%); the excellent and good rate was 80.13%. No significant difference was observed in the wedge angels and displacements of the intervertebral discs between before and after operations (P gt; 0.05). Multiple-factors logistic regression showed that the disease duration and patient’s age had obvious relationship with the effectiveness of treatment (P lt; 0.05), while the type of cervical spondylosis, disc protrusion degree, mild cervical instabil ity, and lesion scope had no correlation with the effectiveness of treatment (P gt; 0.05). Conclusion PLDD is safe and effective in treatment of cervical spondylosis with less compl ication. There is no impact on the stabil ity in cervical spinal constructs. The disease duration and patient’s age have obvious impact on the long-term effectiveness of treatment. The type of cervical spondylosis, disc protrusion degree, cervical instabil ity, and lesion scope are not the correlative factors.
ObjectivesTo investigate and analyze the activities of daily living status and influencing factors for the elderly of long-term care in Shangrao City of Jiangxi Province, and provide a basis for Shangrao City to carry out long-term care insurance for the elderly. MethodsCluster sampling was used to investigate the elderly aged 60 and over in 12 counties (cities, districts)of Shangrao, including the elderly general demographic characteristics and activity of daily living survey. ResultsA total of 1 087 elderly people were surveyed, with an average age of 77.75±8.12 and a total 70.6±21.4 score of activity of daily living. Comparing different age groups, the elder age group had a worse activity of daily living (P<0.001). Those with a higher education level had relatively poor activity of daily living (P<0.001), and those with spouse also had poor activity of daily living (P<0.05). Multiple linear regression analysis showed that age (P<0.001), education level (P<0.001), marital status (P<0.05) and income level (P<0.05) were important factors affecting the scores of activity of daily living of the elderly. ConclusionsAge, education level, marital status, low-income situation, chronic disease, and household registration are the main risk factors affecting the score of the long-term care of the elderly in daily life. The establishment of a long-term care insurance system should be based on chronic diseases, age, marital status and other factors to determine the corresponding long-term care standard scoring system and compensation standards.
ObjectiveTo study the effectiveness of transverse carpal ligament release for carpal tunnel syndrome (CTS) with arthroscopic "two-portal" technique under local anesthesia. MethodsTransverse carpal ligament was released with arthroscopic "two-portal" technique in 31 patients with CTS between November 2002 and August 2008. There were 4 males and 27 females, aged 24-71 years (mean, 52 years). The disease duration was 1 month to 14 years (mean, 42 months). According to the guidelines of Bin Tian, 20 sides were rated as grade I, 16 sides as grade Ⅱ, and 5 sides as grade Ⅲ before operation. The sensation was S2+ in 7 cases, S3 in 19 cases, and S3+ in 5 cases. The muscle strength of the abductor pollicis brevis and opponens pollicis muscles was grade 2 in 5 cases, grade 3 in 14 cases, and grade 4 in 7 cases. Michigan hand function scoring system (MHQ) was used to evaluate the function of the hand before and after operation. ResultsAll incisions healed primarily, and no complications of median nerve injury and adhesion occurred. All of the 31 patients were followed up 6-11.8 years (mean, 9.6 years). After operation, numbness and paresthesia of fingers were relieved (S4); the muscle power returned to grade 4 in 8 cases, and to grade 5 in 23 cases. The MHQ scores of function, daily life, work, pain, appearance, and satisfaction were improved significantly at 6 months postoperatively when compared with preoperative ones (P<0.05). There was no relapse. ConclusionArthroscopic "two-portal" technique is an effective surgical procedure for relieving the compression symptoms on the median nerve from carpal canal, so it is helpful to functional recovery of the median nerve. The long-term effectiveness is definite.
