A perspective on complementary/alternative medicine use among survivors of hematopoietic stem cell transplant: Benefits and uncertainties

The widespread use of complementary and alternative medicine (CAM) in cancer survivors is well known despite a paucity of scientific evidence to support its use. The number of survivors of hematopoietic stem cell transplant (HCT) is growing rapidly and HCT clinicians are aware that many of their patients use CAM therapies consistently. However, due to a paucity of data regarding the benefits and harms of CAM therapies in these survivors, clinicians are reluctant to provide specific recommendations for or against particular CAM therapies. A systematic literature review was conducted with a search using PubMed, the Cochrane Database of Systematic Reviews, and Ovid online for each CAM therapy as defined by the National Center of Complementary and Alternative Medicine. The search generated 462 references, of which 26 articles were deemed to be relevant for the review. Due to extensive heterogeneity in data and limited randomized trials, a meta‐analysis could not be performed but a comprehensive systematic review was conducted with specified outcomes for each CAM therapy. In randomized controlled trials, certain mind and body interventions such as relaxation were observed to be effective in alleviating psychological symptoms in patients undergoing HCT, whereas the majority of the other CAM treatments were found to have mixed results. CAM use is an understudied area in HCT survivorship and clinicians should convey the benefits and uncertainties concerning the role of CAM therapies to their patients.

Primary telangiectatic osteosarcoma of the cervical spine

Telangiectatic osteosarcoma (TOS) is one of the 8 subtypes of osteosarcoma that infrequently affects the spine. The radiopathological features of TOS overlap with those of more benign entities, most commonly the aneurysmal bone cyst), and therefore is a significant diagnostic challenge. It is a rare but well-described entity in the thoracolumbar and sacral spine, and to the authors' knowledge has not been previously reported in the cervical spine. The authors report the case of a 15-year-old boy who presented with a 6-month history of neck pain and torticollis. He underwent preoperative glue embolization followed by a staged subtotal C-5 spondylectomy and posterior fusion for a C-5 vertebral body lytic expansile lesion. Histopathological examination showed the lesion to be TOS. The surgery was followed by adjuvant radiation and chemotherapy with a favorable outcome at the 1-year follow-up. This report reiterates that TOS is an important differential diagnosis for aneurysmal bone cyst and giant-cell tumor of the spine, as its biological behavior and clinical outcome differ from those of these more benign lesions, which it mimics.     

Etiology and management of single small CT lesions in patients with seizures: understanding a controversy

Single, small (less than 1 cm) enhancing lesions are frequent findings on CT scans of Indian patients with seizures. These lesions have also been reported in patients from other parts of the world. They often resolve spontaneously and their etiology has been disputed for over a decade. Initially diagnosed in Indian patients as tuberculomas, a number of other etiologies have been suggested. More recently, based on biopsy data, we have shown that a majority of these lesions are caused by cysticercosis. This review traces the development of the controversy and reports the current understanding of their etiology. A logical approach to their management is also discussed.     

Results of routine ventriculostomy with external ventricular drainage for acute hydrocephalus following subarachnoid haemorrhage

Summary We reviewed the results of ventriculostomy with external ventricular drainage in patients with acute hydrocephalus complicating subarachnoid haemorrhage. Of 194 consecutive patients with subarachnoid haemorrhage admitted during the past eight years, 52 (27%) developed hydrocephalus within 72 hours of the ictus. Patients with acute hydrocephalus were in grades III to V (Hunt and Hess) at the time of evaluation and all patients with hydrocephalus underwent ventriculostomy within 24 hours of diagnosis. Twenty-six patients improved within 24 hours of cerebrospinal fluid drainage and 17 of these patients underwent surgery, nine of whom did well (Glasgow Outcome Scale 1 and 2). All 18 patients who did not improve within this period, including one who worsened, died. In eight patients the response to ventriculostomy was considered as undetermined, because of the proximity of the drain insertion to a definitive surgical procedure, and all of them had an excellent outcome (Glasgow Outcome Scale 1). Of 32 patients in grades IV and V, 17 did not improve and all of them died. Eight of the 15 patients in these grades, who were in the improved or undetermined categories, did well. Five patients (10%) developed meningitis. All patients with this complication had drainage for more than four days. Seven patients (14%) had a rebleed during the drainage. All except one patient with a rebleed had no surgery or delayed surgery and in six of them recurrent haemorrhages occurred after more than 24 hours of drainage.We conclude that routine ventriculostomy with external ventricular drainage should be considered for all patients with altered sensorium and acute hydrocephalus following subarachnoid haemorrhage. The complications of ventriculostomy can be reduced if it is followed by early definitive surgery. No benefit is derived by prolonging the drainage beyond 24 hours in patients in grades IV and V if there has been no improvement in this period, and prolonged drainage may contribute to recurrent haemorrhages and meningitis.     

Continuous impedance monitoring during CT-guided stereotactic surgery: relative value in cystic and solid lesions.

Continuous monopolar impedance monitoring was performed during CT-guided stereotactic procedures involving 46 probe passages in 33 patients. Four readings were obtained during each passage to the lesion corresponding to the gray matter (A), subcortical white matter (B), perilesional tissue (C), and the target (D). The mean impedance of low-grade gliomas (442.7 +/- 96.1 SD ohm) was lower than that of high-grade gliomas (675 +/- 67.3 SD ohm) (p = 0.01). But because of considerable overlap of values in the 400-700 ohm range only impedances of less than 400 ohm and greater than 700 ohm are capable of predicting pathology, the former being associated with low-grade gliomas and the latter with high-grade gliomas. The mean change in impedance from the perilesional tissue to the target (C-D) was higher for cystic lesions compared with the solid lesions (127.5 +/- 131.5 SD versus 78.9 +/- 72.4 SD ohm) but was not statistically significant (p = 0.148). Impedance monitoring was found to be particularly useful in determining the entry into thick-walled cysts. It also helped elucidate the structures encountered in the probe track. Overall this procedure is a simple and useful adjunct, which can enhance the accuracy of selected CT-guided procedures without unduly increasing the length of the procedure or altering the morbidity.     

Pelvic floor surgery in the older woman: enhanced compared with usual preoperative assessment

OBJECTIVE: To examine whether knowledge of deficits obtained in a preoperative geriatric assessment may benefit postoperative health outcomes in older women undergoing pelvic surgery. METHODS: This study employed a pre-post intervention cohort design. Primary outcome was difference in scores of the Physical Component Summary and Mental Component Summary of the Medical Outcomes Study Short Form 36 Health Survey in 62 older women who had undergone "usual" compared with an "enhanced" preoperative assessment consisting of Activities of Daily Living, Instrumental Activities of Daily Living, Get Up and Go Test, Draw a Clock Test, Mini Nutritional Assessment, Geriatric Depression Scale, and Social Support Scale. The assessment results were placed on the participant's hospital chart. Repeated measures analysis was used. RESULTS: There were no significant differences in Mental Component Summary scores between the usual and enhanced assessment cohorts preoperatively (mean +/- standard deviation; 49.14 +/- 10.61 compared with 53.2 +/- 9.33), at 6 weeks (53.69 +/- 8.61 compared with 55.47 +/- 9.46), or at 6 months postoperatively (53.85 +/- 10.77 compared with 56.25 +/- 7.25); P = .120 for group effect and P = .798 for group by time interaction. Significant time effect was noted (P = .036). There was no significant difference in Physical Component Summary scores between the usual and enhanced assessment cohorts with respect to group effect (P = .986); there was a significant time effect (P = < .001) and a significant group by time interaction (P = .026). Satisfaction with treatment was high in both cohorts at 6 weeks and 6 months. CONCLUSION: A preoperative geriatric assessment did not seem to have differential benefit in healthy older women undergoing elective pelvic floor surgery. LEVEL OF EVIDENCE: II-2.     

Stereotactic craniotomy for lesions in eloquent areas

CT compatible stereotactic systems are being increasingly used in the management of intracranial mass lesions. This study deals with the use of BRW stereotactic system for excisional biopsy of small (<30 mm), superficial, solitary cerebral lesions located in eloquent areas. Out of a total of 113 cases of stereotactic craniotomy carried out in the department since 1987, 78 fitted the above criteria. Out of these 78 patients, 70 lesions (90%) were less than 20 mm in size. Local anaesthesia was used in 10 cases (13%) whereas the rest had general anaesthesia. Cortical incision using standard techniques were used in 51 patients (65%), whereas in 27 patients (35%) excisional biopsy was done using trans-sulcal microsurgical techniques. Twenty-one (41%) patients had some degree of neurological deficit in the immediate postoperative period when a cortical incision was used compared to 4 patients (15%) when a trans-sulcal microsurgical excisional biopsy was done (P < 0.05). However, significant neurological deficits were present in 10 cases (12.8%) and all but two had had cortical incisions. When assessed one month after surgery significant residual deficit was present in only 2 patients (2.5%) who had had cortical incisions. There was no postoperative infection or mortality in this series. CT guided stereotactic craniotomy coupled with trans-sulcal microsurgical techniques can be safely used for the excisional biopsy of small superficial lesions located in eloquent areas of the brain.
