Comparative Efficacy of Vertebroplasty,Kyphoplasty, and Medical Therapy for Vertebral Fractures on Survival and Prevention of Recurrent Fractures

ObjectiveTo evaluate the efficacy of surgical and medical therapies on recurrent vertebral fracture and mortality rates.MethodsA retrospective review of medical records was performed of patients seen at Emory University Spine Center and Hospital (Atlanta, Georgia) for vertebral fracture between 1998 and 2007. Patients with vertebral fracture or who underwent vertebroplasty or kyphoplasty were identified by use of the International Classification of Diseases, Ninth Revision and Current Procedural Terminology codes, respectively. Outcome measures included site and date of recurrent vertebral fractures and mortality.ResultsWe identified 250 patients with vertebral fractures and classified them into 4 groups: surgical therapy only, surgical plus medical treatment, medical therapy only, and no treatment. There was no significant difference in the cumulative survival rates among the 4 study groups nor between the treatment groups. There was, however, a significant difference in the cumulative refracturefree rates among the 4 study groups (P < .0001). Recurrent fracture-free rates were highest in the group that received no treatment. The 2-year cumulative refracture-free rates were 95.9%, 84.8%, 81.7%, and 68.5%, respectively, for the no treatment, medical therapy only, surgical treatment only, and medical plus surgical therapy groups. Recurrent fracture-free rates were significantly different for patients who received surgical or medical or surgical plus medical therapy (P = .0007), with patients in the medical plus surgical group having the shortest time to refracture, although these patients may have been sicker and more frail than the other groups.ConclusionWe found that surgical treatment with vertebroplasty or kyphoplasty did not decrease recurrent vertebral fractures in patients presenting with an initial vertebral fracture. Medical and surgical therapies together may shorten the time to refracture, but the observed elevated risk may be due to other confounding factors. We found no difference in survival in patients undergoing kyphoplasty or vertebroplasty in comparison with medical or no treatment groups. The relationship between surgical and medical therapy and vertebral refracture rates should be further evaluated with use of a prospective cohort design. (Endocr Pract. 2012;18:499-507)     

Cancer de la vulve: Etude clinique de 46 cas

Vulvar carcinoma is found primarily in elderly and postmenopausal women. Most patients unfortunately seek medical advice too late and only after various inadequate treatments have been applied. Radical vulvectomy is the treatment of choice in cases of epidermoid carcinoma. For the patients in the series reported who received adequate surgical treatment, the five-year survival rate was 71.4%, while for those who were inadequately treated it was only 11%.     

Intensity of thrombin activity and surgical trauma

Increased level of in vivo thrombin activity represents the essential mark of prethrombotic state. In order to assess the influence of surgical trauma on the constitution of prethrombotic state immediately after the surgical intervention, dynamic estimations of fibrinopeptide A (FPA) have been done in a group of 18 patients who had undergone abdominal surgery and in the group of 25 patients who underwent the replacement of artificial hip, and who were on preventive treatment with subcutaneous heparin. At the same time the presence of soluble fibrinmonomer complex and, in the group of patients on heparin treatment, the concentration of plasma heparin were examined. The investigations were done before the surgical intervention and on the first, third and seventh postoperative day. Our dynamic study showed the existence of certain relation between the surgical trauma and values of FPA which were the expression of intensity of in vivo thrombin activity. The mean values of FPA increased markedly on the first postoperative day in comparison with the preoperative levels. On the third postoperative day significant reduction of FPA was observed and on the seventh day marked increase was found only in patients who were not on heparin prevention. Although preventive application of subcutaneous heparin did not affect the whole blood coagulability it showed a suppressive impact on the thrombin activity level in examined surgical patients.(ABSTRACT TRUNCATED AT 250 WORDS)     

Isolated capitellum humeri fractures in adults

From 2003 through 2009 we treated 35 patients who suffered from an isolated capitellum humerus fracture whom we treated with osteosynthesis. Patients who presented with concomitant fractures were not included. Thirty-four patients were categorized as Type I (Hahn-Steinthal) while one patient was Type IV (McKee). We describe the mechanism of injury and compared our results with works available in the literature. The average age of our patients was 38.6 years which was much younger than many articles about this type of injury found in the literature. The ratio of women to men in our study was 20:15. The surgical treatment was performed with various methods including: Kirschner wires, AO screws, Herbert screws and TwinFix screws. We discuss type of injury, days after injury operative treatment is performed, type of osteosynthesis used, the surgical approaches used for our treatment of capitellum humeri fractures, possible complications and our postoperative treatment. Results at the conclusion of treatment were excellent. Range of motion, shown in detail for each patient, was measured preoperatively, 1 month and 3 months postoperatively. We concluded that the major factors in successful treatment are how quickly the surgical treatment is performed after injury and early postoperative rehabilitation.     

Pregnancy termination with the PGE2-analogue SHB 286.

A group of 94 volunteers were treated with PGE2-analogue SHB 286 at the 12+1 week of pregnancy. Of the 94 gravidas, 78 received a single extravular dose of 50-200 microgram (Mean +/- S.E. 76 +/- 7 microgram) while 16 a short intravenous infusion of 1000-2000 microgram SHB 286. Despite the single treatment and low dose, the success rate was 69% and the instillation abortion time only 15 +/- 1 hours. At 24 hours after treatment even those gravidas who failed to abort (31%) had sufficient cervical dilatation for curettage and thus could be spared from rapid surgical dilatation. Peripheral plasma progesterone and estradiol-17 beta decreased significantly at 4 hours after treatment in those gravidas who subsequently aborted. After an initial contracture response of the uterus to SHB 286, the cyclic intraterine pressure evolved gradually. In 4 hours it reached significantly higher levels in those gravidas who subsequently aborted than in those who did not.     

District Nursing Sister Attached to Hospital Surgical Department

An experiment of attaching a district nursing sister to the surgical department of a general hospital was designed to show the use of the district nursing service for the after-care of patients discharged from hospital after surgical treatment. In a 15-week period about 590 bed days were saved, and only six out of 126 patients discharged early had to be readmitted. Most of the patients and the general practitioners who replied to questionaries about the scheme were in favour of it.     

Surgical treatment of aortic dissection in a patient with metastatic prostate cancer

Acute aortic dissection bears all the stigmata of a true clinical emergency. The natural history of this acute aortic syndrome warrants prompt surgical intervention, with only a few absolute contraindications to this line of treatment. We present a 74-year-old man with documented metastatic prostate cancer who underwent emergent surgery for acute Stanford A aortic dissection. Having acknowledged the relatively favorable evolution of our patient's malignant disease, we were not deterred by its presence from pursuing surgical treatment of his aortic dissection.     

Carcinoma of the cervix

Studies by eminent surgeons to reevaluate the place of radical operations in the treatment of carcinoma of the cervix-now that extensive procedures have become less hazardous-apparently have led to confusion in some minds as to choice between surgical and radiation therapy. Pending outcome of the studies, general employment of surgical treatment is unwarranted. Radiation is the treatment of choice in most cases, particularly if the lesion is in an early stage, although radical operation is indicated in certain rare early cases in which delivery of an effective dose of radiation to involved areas is technically difficult. Elsewise it appears at present that operation should be used only in cases of stages III or IV carcinoma-in which results by either means of treatment are poor.One hundred and seven patients were treated with a combination of x-ray and radium irradiation. X-ray was used first to reduce the hazard of implanting the radium. The "five-year arrest" rates were as follows: For 22 patients with stage I lesion, 70 per cent; for 31 with stage II, 55.7 per cent; 33 with stage III, 39.7 per cent; 21 with stage IV, 0. Eighteen patients with diagnosis of carcinoma of the cervix who had had subtotal hysterectomy were treated. The stage of the disease could not be determined. In this group the five-year arrest rate was 52 per cent.     

Controlled trial of azathioprine in chronic ulcerative colitis.

A double-blind controlled trial of azathioprine in a dose of 2-2.5 mg/kg body weight over six months was conducted among 44 patients with active chronic ulcerative colitis. Three patients treated with placebo did not complete the trial because their disease became so severe that colectomy was performed. Among patients who completed the trial the mean dose of prednisolone necessary to control the disease decreased in those treated with azathioprine and those treated with placebo; the reduction was greater among those who took azathioprine (p less than 0.001). Activity of the disease apparently improved in both treatment groups but a significant (p less than 0.001) trend was observed only in those patients treated with azathioprine. No serious side effects from azathioprine occurred during the trial but seven of 24 patients had to stop the drug because of nausea. Azathioprine may have a role in the treatment of a few patients wih troublesome chronic colitis for whom conventional drug treatment is ineffectual, or for whom continuous systemic corticosteroid treatment is needed to control symptoms, and for whom surgical treatment is inappropriate.     

Is the treatment of axillary osmidrosis with liposuction better than open surgery?

Axillary osmidrosis is an annoying, although not life-threatening, problem that includes unpleasant odor and the occasional staining of clothing. Suction-assisted lipectomy has been tested as a treatment for axillary osmidrosis with variable success. The authors retrospectively reviewed 134 patients who underwent superficial liposuction for bilateral axillary osmidrosis in their division between June of 1998 and June of 2002. The surgical complications and results were compared with those reported in their previous report of 343 patients (102 available for postoperative result evaluation) who received open surgical treatment with partial excision of axillary skin and subcutaneous tissue. The overall complication rate was 3.73 percent, significantly lower than the 11.08 percent complication rate seen with open surgical treatment. Of their 134 patients, 114 were available for long-term follow-up. Thirteen patients (11.40 percent) had very good results, 79 patients (69.30 percent) had good results, and 22 patients (19.30 percent) had poor results. Significant differences were found between those who underwent superficial liposuction and those who underwent open surgery. The number of patients with very good and good results decreased significantly from 91.18 percent (open surgery) to 80.70 percent (liposuction), and those with little or no improvement increased from 8.82 percent (open surgery) to 19.29 percent (liposuction). Compared with open surgery for the treatment of osmidrosis, liposuction produces significantly fewer complications but is less effective. Of the patients who underwent liposuction for osmidrosis, 80 percent were satisfied with the result. Further study is needed to determine whether liposuction for osmidrosis can be improved.     

Adoptive immunotherapy of breast cancer with lymph node cells primed by cryoablation of the primary tumor

Cryoablation of cancer leaves tumor-associated antigens intact in an inflammatory microenvironment that can stimulate a regional anti-tumor immune response. We examined whether cryoablated tumor draining lymph nodes (CTDLN) as adoptive immunotherapy may be an effective immunotherapeutic approach in the adjuvant treatment of breast cancer. BALB/c mice with MT-901 mammary adenocarcinoma tumors underwent cryoablation, resection or no treatment and tumor draining lymph nodes were harvested. Cryoablation resulted in only a mild increase in the absolute number of T-cells but a significant increase in the fraction of tumor-specific T-cells as evidenced on IFN-gamma release assay. FACS analysis demonstrated no significant relative shift in the proportion of CD4(+) or CD8(+) cells. The adoptive transfer of CTDLN resulted in a significant reduction of pulmonary metastases as compared to TDLN from either tumor-bearing mice or mice who underwent surgical excision. Cryoablation prior to surgical resection of breast cancer can be used as a method to generate effector T-cells for adjuvant adoptive cellular immunotherapy.     

Evaluation of nodal patterns for melanoma of the ear

Treatment of malignant melanoma of the external ear presents unique challenges. Because of the significant debate regarding the efficacy and validity of using sentinel lymph node mapping for the treatment of ear melanomas, data for a population of patients with melanomas of the ear who underwent surgical excision and reconstruction were reviewed to determine the efficacy of sentinel node mapping. A retrospective chart review of cases treated by a single surgical oncologist was performed. All patients who were treated for malignant melanomas and required reconstruction of the external ear by the plastic surgical service between 1995 and 2001 were identified. Nineteen patients were selected, of whom nine underwent sentinel node mapping. The average age of the patients was 65.2 years. Evaluation of melanoma depth, medical history, surgical margins, lymph node metastasis, and recurrence was performed. Lymphoscintigraphy with technetium-99-sulfur colloid and 1% Lymphazurin (isosulfan blue; Zenith Parenterals, Rosemont, Ill.) demonstrated widely variable lymphatic drainage patterns. The lower tail of the parotid gland and the upper cervical area were the two most common locations. The average number of sentinel nodes identified and removed was 3.7. The average Breslow thickness for these patients was 2.3 mm. None of these patients demonstrated micrometastatic disease in their sentinel nodes. The most common reconstructive procedure after surgical resection was the use of rotational advancement flaps. Localization of radioactivity, as detected with external technetium-99 scanning, was the most reliable method for detection of the sentinel lymph node basins and the individual nodes. The average value for the primary injection site was 8375 counts per second, and the average value for the nodes removed was 973.5 counts per second. Of the nine patients who underwent sentinel lymph node mapping, only one, with an initial lesion depth of 5 mm, developed a local recurrence. The average follow-up period in this study was 21 months (range, 12 to 79 months). All patients in this study were evaluated at least 1 year after the initial surgical resection. Patients were monitored by the same surgical oncologist every 3 months for the first 2 years. Little can be found in the literature regarding the efficacy of sentinel node biopsies for ear melanomas. Larger studies are indicated; however, it seems that this method is practical for designing therapeutic methods for patients with melanoma of the ear.     

Disparities in surgical treatment of early-stage non-small-cell lung cancer.

This study involved 1,564 black or white patients diagnosed in 1992 to 1997 with non-small-cell lung cancer, reported to the population-based Connecticut Tumor Registry, who were linked with a statewide hospital discharge database that provided information on comorbid conditions. While only 11.4 percent of patients did not receive surgical treatment (lung resection), this proportion increased with rising age and was higher among patients who resided in a census tract in the highest poverty-rate quintile, were black, not married and had one or more selected comorbid conditions. These associations persisted in logistic regression models that included all of the variables as predictors of surgery. Studies are needed to explain these disparities.     

CARCINOMA OF THE CERVIX

Studies by eminent surgeons to reevaluate the place of radical operations in the treatment of carcinoma of the cervix—now that extensive procedures have become less hazardous—apparently have led to confusion in some minds as to choice between surgical and radiation therapy. Pending outcome of the studies, general employment of surgical treatment is unwarranted.

Selection of operation in patients with bleeding esophageal varices.

The results of surgical treatment of bleeding esophageal varices over an 8-year period in 155 patients are reviewed. Primary treatment of bleeding was conservative, with intravenous administration of vasopressin and balloon tamponade. Emergency operations were carried out after 48 hours in persons with persistent bleeding who were surgical candidates. Operative mortality was higher in this group (40%) than in those undergoing elective or urgent operations (each 10%). Postoperative encephalopathy occurred in 35% of patients and was correlated closely to late death after establishment of a shunt. The mesocaval shunt is no better than the portacaval but appears to be a good alternative in an emergency. In a controlled trial the distal splenorenal shunt was found to be associated with a lower rate of postoperative encephalopathy than the portacaval shunt, but thus far the long-term survival rates have not differed.

Pregnancy termination with the PGE2-analogue SHB 286

A group of 94 volunteers were treated with PGE₂-analogue SHB 286 at the 12±1 week of pregnancy. Of the 94 gravidas, 78 received a single extraovular dose of 50–200μg (Mean±S.E. 76±7μg) while 16 a short intravenous infusion of 1000–200μg SHB 286. Despite the single treatment and low dose, the success rate was 69% and the instillation-abortion time only 15±1 hours. At 24 hours after treatment even those gravidas who failed to abort (31%) had sufficient cervical dilatation for curettage and thus could be spared from rapid surgical dilatation.Peripheral plasma progesterone and estradiol-17β decreased significantly at 4 hours after treatment in those gravidas who subsequently aborted. After an initial contracture response of the uterus to SHB 286, the cyclic intrauterine pressure evolved gradually. In 4 hours it reached significantly higher levels in those gravidas who subsequently aborted than in those who did not.     

Evaluation and Treatment of Osteoporosis in Patients with a Fragility Hip Fracture

ObjectiveTo determine whether patients with fragility hip fractures underwent assessment and treatment of osteoporosis during initial hospitalization or recommendations for such intervention were made to the primary care provider (PCP) at the time of hospital dismissal.MethodsA review of medical records of patients admitted with a low-impact hip fracture to the Royal University Hospital in Saskatoon, Saskatchewan, Canada, was performed to determine whether recommendations were made to evaluate for or treat osteoporosis. In addition, a questionnaire was sent to the orthopedic surgeons practicing at the hospital to help identify barriers to widespread diagnosis and treatment of osteoporosis in such patients.ResultsBetween January and December 2004, 174 patients with fragility hip fractures were admitted to the Royal University Hospital. The mean age of these patients was 82.5 ± 9.8 years. Evaluation for treatment of osteoporosis was recommended in only 9 patients (5%). We found no significant differences in the intervention rates between male and female patients, between patients with and those without a prior history of osteoporosis or fracture, between patients who were previously taking osteoporosis medications and those who were not, and between patients who were seen by a medical consultant and those who were not. Most orthopedic surgeons believed that they were primarily responsible for the surgical care of these patients, and because they did not see these patients in regular follow-up, the management of osteoporosis was considered the responsibility of the PCP.Conclusion: The results of this study indicate that only a small number of patients with fragility hip fractures receive appropriate evaluation or treatment for underlying osteoporosis either during initial hospitalization or at the time of dismissal from the hospital. In this study, most orthopedic surgeons believed that evaluation and treatment of osteoporosis were the responsibility of the PCP. Because these patients have an increased risk for future fractures, barriers to the diagnosis and treatment of osteoporosis need to be removed, and health-care professionals need to be educated about appropriate risk factor modification in these patients.

Hynes pharyngoplasty revisited

The treatment of velopharyngeal incompetence remains unsatisfactory because the causes are many, as are the variations in anatomic and physiologic defects. Therefore, full assessment and investigation are essential in tailoring the surgery to the defect. A modified Hynes pharyngoplasty has been used in 40 patients, aged 4 to 52, over a 4-year period for velopharyngeal incompetence of varying etiologic causes. Speech was assessed before and at least 6 months after pharyngoplasty. At the same time, radiologic and, when possible, nasendoscopic investigations were undertaken. Thirty-eight patients had no or variable nasal escape (variable defined as achieving intermittent closure), whereas 33 had normal or slight hyponasal resonance. There was only one complication, an asymptomatic dehiscence of the "bucket handle" flap from the posterior wall. Thirteen patients had an assortment of side effects, none requiring surgical treatment. We believe that patients who are suitable for the described sphincter pharyngoplasty are those with slight or moderate nasal escape having a mobile palate with an anteroposterior gap of 5 mm or less.     

Platelet-rich plasma improves wound healing in multiple myeloma bisphosphonate-associated osteonecrosis of the jaw patients

Bisphosphonates are drugs used to treat various metabolic and malignant bone diseases. In the past 10 years intravenous bisphosphonates have been associated with increased risk of osteonecrosis of the jaw (ONJ). The aim of the present study is to evaluate platelet-rich plasma (PRP) wound healing benefits in multiple myeloma (MM) patients who developed ONJ after surgical tooth extraction. The study included 7 patients, 2 males and 5 females. All individuals had been taking zoledronate or pamidronate followed by zoledronate for an average of 5 years. Four subjects had only standard surgical debridement and sequestrectomy to treat the ONJ and three had additional autologous PRP. The patients were followed-up for 3 months. The use of PRP to enhance wound healing and reduce bone exposure seems to be a good treatment protocol in ONJ MM subjects.
