Introduction

Experience in thoracoscopic congenital diaphragmatic hernia (CDH) repair has expanded, yet efficacy equal to that of open repair has not been demonstrated. In spite of reports suggesting higher recurrent hernia rates after thoracoscopic repair, this approach has widely been adopted into practice. We report a large, single institutional experience with thoracoscopic CDH repair with special attention to recurrent hernia rates.

Methods

We reviewed the records of neonates with unilateral CDH repaired between January 2006 and February 2010 at Morgan Stanley Children's Hospital. Completely thoracoscopic repairs were compared to open repairs of the same period. In addition, successful thoracoscopic repairs were compared with thoracoscopic repairs that developed recurrence. Data were analyzed by Mann-Whitney U and Fisher exact tests.

Results

Thirty-five neonates underwent attempted thoracoscopic repair, with 26 completed. Concurrently, 19 initially open CDH repairs were performed. Preoperatively, patients in the open repair group required more ventilatory support than the thoracoscopic group. Recurrence was higher after thoracoscopic repair (23% vs 0%; P = .032). In comparing successful thoracoscopic repairs to those with recurrence, none of the factors analyzed were predictive of recurrence.

Conclusions

Early recurrence of hernia is higher in thoracoscopic CDH repairs than in open repairs. Technical factors and a steep learning curve for thoracoscopy may account for the higher recurrence rates, but not patient severity of illness. In an already-tenuous patient population, performing the repair thoracoscopically with a higher risk of recurrence may not be advantageous.  相似文献

OBJECTIVES: Low-frequency repetitive transcranial magnetic stimulation (rTMS) of the temporal cortex has been proposed as a new treatment strategy for patients with chronic tinnitus. However, functional abnormalities in tinnitus patients also involve brain structures used for attentional and emotional processing, such as the dorsolateral prefrontal cortex. Therefore, we have developed a new rTMS treatment strategy for tinnitus patients that consists of a combination of high-frequency prefrontal and low-frequency temporal rTMS. STUDY DESIGN: A total of 32 patients received either low-frequency temporal rTMS or a combination of high-frequency prefrontal and low-frequency temporal rTMS. Treatment effects were assessed with a standardized tinnitus questionnaire (TQ). RESULTS: Directly after therapy there was an improvement of the TQ-score for both groups, but no differences between groups. An evaluation after 3 months revealed a remarkable benefit from the use of combined prefrontal and temporal rTMS treatment. CONCLUSION: These results support recent data that suggest that auditory and nonauditory brain areas are involved in tinnitus pathophysiology.  相似文献

OBJECTIVE: Assessment of myocardial viability by 99mTc-Sestamibi Single Photon Emission Computerized Tomography (SPECT) has been suggested as a more readily available and cheaper alternative to Positron Emission Tomography (PET) with 13N-ammonia (NH3) and 18F-fluoro-deoxy-glucose (FDG). We hypothesized that a semi-quantitative evaluation by SPECT could delineate myocardial viability with an acceptable concordance to PET. DESIGN: Fifty patients (age 57+/-7 years; ejection fraction 28 +/- 8%), with ischemic cardiomyopathy, underwent SPECT and PET imaging in random order. Viability by SPECT was defined as a defect size <50% of the segment area, or a defect representing > or =50% of the segment but with a mean activity > or =50% of peak activity. PET viability was defined as a perfusion score >2 and FDG score < or =2 (five-point scale, 0 = normal, 4 = absent activity). RESULTS: By segmental comparison to PET. SPECT yielded a sensitivity and specificity of 87% and 82% for detection of viable myocardium. The positive and negative predictive values were 96% and 58%, respectively. CONCLUSION: In patients with severe ischemic cardiomyopathy 99mTc-Sestamibi SPECT can delineate viable myocardium with an acceptable segmental concordance to NH3/FDG PET.  相似文献

BACKGROUND: Botulinum toxin A (BTX-A) injections are a commonly used and effective therapy for patients with focal axillary hyperhidrosis. However, injections are often painful. Therefore, we studied whether skin cooling decreases pain during injection. METHODS: Thirty-one patients (n = 31) with focal axillary hyperhidrosis were enrolled in the present study. Patients were treated with 50 MU BTX-A (Botox; Allergan, Irvine, CA) in each axilla. One group (n = 21) received a skin cooling using a cold-air system (SmartCool; Cynosure, Westford, MA) versus no cooling on the other side. In the second group (n = 10), patients were cooled with the same cold air blower on one axilla and ice cubes on the other. For evaluation of the effect of cooling in both groups, relative pain scores using a visual analog scale (VAS) were recorded. RESULTS: In the first group, the air-cooled-side pain scores ranged from 0 to 4 (average: 2.5) versus 5 to 10 (average: 7.4) on the noncooled side. The air-cooled side showed a 66.2% higher reduction in pain score. In the second group, no significant difference was seen between air and ice cooling (average pain score 2.0 versus 2.4; P > 0.05). CONCLUSION: Skin cooling decreases pain during injection of BTX-A in patients with focal axillary hyperhidrosis, with ice and air cooling showing the same efficacy.  相似文献

BACKGROUND CONTEXT

Anterior cervical discectomy and fusion (ACDF) without and with cervical plating (ACDF+CP) are accepted surgical techniques for the treatment of degenerative cervical disc disorders. The effect of CP on the development of adjacent segment degeneration (ASD) remains unclear.

PURPOSE

To assess whether CP accelerates the degeneration of the adjacent and adjoining segments.

STUDY DESIGN/SETTING

This is an imaging cohort study.

PATIENT SAMPLE

Retrospectively, a total of 84 patients who underwent ACDF or ACDF+CP were identified. At final follow-up, an MRI was performed and evaluated in this study.

MATERIALS AND METHODS

An MRI of 84 patients who underwent ACDF (46 patients) and ACDF+PS (38 patients) was performed. The mean follow-up was 24 years (17–45 years). None of the patients had a repeat procedure in the cervical spine. The grade of degeneration of the segments adjacent and adjoining to the fusion was assessed via a five-step grading system (segmental degeneration index, or SDI) that includes disc signal intensity, anterior and posterior disc protrusion, narrowing of the disc space, and foraminal stenosis. Furthermore, the disc height (DH) and sagittal segmental angle (SSA) of fused segments were measured.

RESULTS

A significantly (p<.001) greater SDI was identified at the caudal adjacent segment following ACDF compared to ACDF+CP. No other significant differences were identified in patients following ACDF and ACDF+CP. Between 50% and 96% of all segments showed severe degenerative changes according to SDI. There was no significant difference in DH between the patients following ACDF and ACDF+CP. The SSA in patients who underwent ACDF+CP was significantly greater than in the ACDF patients (p=.002).

CONCLUSIONS

In this cohort of patients, cervical plating had no significant impact on segmental degeneration and decrease of DH in the adjacent and adjoining segments. ACDF+CP seem to preserve the lordotic alignment more with respect to the SSA than ACDF.  相似文献

The purpose of this study was to examine the outcome of attempted radical surgical resection in patients with stage IV neuroblastoma. Between 1989 and 2003, 20 (median age 2.4 years, range 0.5–8.7 years) children with stage IV neuroblastoma were treated at the Department of Pediatrics. Surgery was performed in 7 consecutive children (6 male and 1 female) between July 1997 and February 2002 at the Department of Urology in Bonn. Mean age at diagnosis was 57 months (21–104 months). Mean age at the time of surgery was 54 months (8–390 months). Follow-up was available for all patients (100%) and mean follow-up after the operation was 32.5 months (4–56 months). Primary localization of the tumor was retroperitoneal in all cases; 4 out of 7 patients (57%) also had additional adrenal, 3 out of 7 (42%) paraganglion and 1 out of 7 (14%) thoracic primaries. Bone marrow and lymph node metastases were found in all patients (100%). Surgery led to complete tumor resection in 6 out of 7 patients (85%). Surgical approach was abdominal (chevron incision) in 6 out of 7 (85%) of the patients, in one patient the approach was thoraco-abdominal. After induction chemotherapy and delayed surgery, 6 out of 7 (86%) patients showed a complete remission (CR) and the mean CR lasted for about 27.7 months (range 3.1–55.4 months). At the last time of follow-up 5 out of 7 (71%) patients were alive, 2 had died due to recurrent disease. Mean time to recurrent disease was 24 and 51 months, respectively. Mean overall survival time since diagnosis was 38.3 months (11–64 months) and mean event-free survival was 34.5 months (11–60.3 months). The final outcome, overall survival and event-free survival time was influenced by metastatic or local relapse. Tumor resection is beneficial but the value of surgery can only be judged when we are able to control metastatic disease in stage IV neuroblastoma. The final outcome may rely on the extent of complete surgical resection, but is also related to treatment of metastases. A longer follow-up period is indicated to detect long term outcome.  相似文献

The number of small and often asymptomatic cystic lesions detected in pancreas has increased during the last decade. Historically the vast majority of the pancreatic cystic lesions were considered pseudocysts, but in recent series the incidence of various neoplastic cysts, such as intraductal papillary mucinous neoplasm, serous cystadenomas and cystic endocrine tumours, has increased. The possible malignant potential in these cystic neoplasms warrants careful diagnostic workup to choose the optimal treatment for each patient. Patient's age, symptoms and a possible history of acute or chronic pancreatitis with known aetiology together with high quality imaging studies are important in the differential diagnosis between pseudocysts and neoplastic cysts. Endoscopic ultrasound, cyst fluid analysis and positron emission tomography may be used in selected patients, but the accuracy of these methods needs further investigation.  相似文献

BACKGROUND AND OBJECTIVES: Continuous femoral nerve block is a well-accepted technique for regional analgesia after total-knee replacement. However, many patients still experience considerable pain at the popliteal space and at the medial aspect of the knee. The goal of this study is to evaluate whether a psoas compartment catheter provides better postoperative analgesia than a femoral nerve catheter does and whether it is as effective as the combination of a femoral and a sciatic nerve catheter and, thus, improves functional outcome. METHODS: Ninety patients who underwent total-knee replacement under standardized general anesthesia participated in this prospective randomized study. Group FEM received a continuous femoral nerve block, group FEM/SCI received a combination of a femoral and a sciatic continuous nerve block, and group PSOAS received a continuous psoas compartment block. Patient-controlled analgesia with piritramide was available for 48 hours. Maximal bending and extending of the knee and walking distance was assessed during the first 7 days. A standardized telephone survey was conducted after 9 to 12 months to evaluate residual pain and functional outcome. RESULTS: Postoperative opioid consumption during 48 hours was significantly less in the FEM/SCI group (median: 18 mg; 25th/75th percentile: 6/40) compared with the FEM group (49 mg; 25/66) and the PSOAS group (44 mg; 30/62) (P =.002). Postoperative pain scores were not different, and no differences occurred with respect to short-term or long-term functional outcome. CONCLUSION: The FEM/SCI catheter is superior to FEM and PSOAS catheter with respect to reduced analgesic requirements after total-knee replacement, but functional outcome does not differ with those 3 continuous regional analgesia techniques.  相似文献

During a 6-month-period, 150 patients infected with Human Immunodeficiency Virus (HIV) were repeatedly examined by dermatologists and dentists for lesions of skin and oral mucosa. The most frequently encountered diseases were: oral hairy leukoplakia (21%), dermatophytosis (including tinea unguium/tinea pedis et inguinalis) (20%), seborrheic dermatitis (19%), viral infections (10%), oral candidiasis (7%), acne vulgaris (6%), and folliculitis (5%). A variety of other manifestations were seen, with frequencies less than 5%. Herpes zoster was seen in 3% of the patients, indicating a rate of 60/1,000 per annum. The presence of seborrheic dermatitis was statistically associated with low T-helper lymphocyte count. Patients with low T-helper lymphocyte count had on average twice as many mucocutaneous lesions as patients with a normal or moderately decreased count. Any one of the manifestations seborrheic dermatitis, oral candidiasis or oral hairy leukoplakia was associated with a greater average number of additional mucocutaneous changes than seen in patients exhibiting none of these three conditions. The high proportion of HIV-infected patients with cutaneous and oral lesions underlines the importance of referring the patients to dermatologists and dentists for examination. Prospective examinations of the study population remain to elucidate the prognostic significance of mucocutaneous manifestations of HIV-infected patients.  相似文献
