Long-term follow-up of achalasic patients treated with botulinum toxin

DISEASES OF THE ESOPHAGUS, Issue 2 2000
D'Onofrio
Botulinum toxin A (BoTx), a potent inhibitor of acetylcholine release from nerve endings both within the myenteric plexus and at the nerve,muscle junction, has been shown to decrease the lower esophageal sphincter (LES) pressure in patients with achalasia. Because of this property, the esophageal injection of BoTx has been suggested as an alternative treatment in achalasia. The objective of this study was to determine the long-term efficacy and safety of intrasphincteric injection of BoTx in a group of achalasic patients. Nineteen patients (mean age 56.1 ± 19.2 years) were enrolled in the study. All of them were injected endoscopically with 100 U of BoTx by sclerotherapy needle at different sites of the LES. Symptom score (dysphagia, regurgitation and chest pain, each on a 0,3 scale), esophageal manometer and esophageal radionuclide emptying were assessed before the treatment and at 4 weeks, 3 months and 1 year after BoTx injection. In case of failure or relapse (symptom score >2), the treatment was repeated. All but five patients (74%) were in clinical remission at 1 month. Mean symptom score after 1 month of BoTx decreased from 7.1 ± 0.9 to 2.2 ± 2.5 (p < 0.05). LES pressure decreased from 38.4 ± 13.7 to 27.4 ± 13.5 mmHg (p < 0.05) and 10-min radionuclide retention decreased from 70.9 ± 20.7% to 33.8 ± 27.0% (p < 0.05). Side-effects (transient chest pain) were mild and infrequent. At 12 months, the clinical score was 0.9 ± 0.5 (p < 0.05 vs. basal); mean LES pressure was 22.0 ± 7.1 (p < 0.05 vs. basal) and 10-min radionuclide retention was 15.8 ± 6.0% (p < 0.05 vs. basal). The efficacy of the first injection of BoTx lasted for a mean period of 9 months (range 2,14 months). At the time of writing (follow-up period mean 17.6 months, range 2,31), 14 patients (10 with one injection) were still in remission (74%). Our results showed that one or two intrasphincteric injections of BoTx resulted in clinical and objective improvement in about 74% of achalasic patients and are not associated with serious adverse effects; the efficacy of BoTx treatment was long lasting; this procedure could be considered an attractive treatment, especially in elderly patients who are poor candidates for more invasive procedures.

Allogeneic bone marrow transplantation with reduced conditioning (RC-BMT)

EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 2 2001

Abstract: Allogeneic bone marrow transplantation with conventional conditioning (CC-BMT) has the potential of curing various malignant and non-malignant diseases. The curative mechanisms encompass 1) stem cell support for myeloablative radio-chemotherapy, 2) the graft-versus-tumor (GVT) effect, 3) gene replacement for genetic diseases and 4) immunoablation for autoimmune diseases. CC-BMT is characterized by high intensity conditioning, the requirement of prolonged and expensive hospital treatment and a treatment related mortality (TRM) of 10,50% depending on diagnosis, disease stage, patient age and donor type. Recent preclinical and clinical progress has resulted in the emergence of new concepts and procedures that allow replacement of patient bone marrow and immune system with that of the donor by a transplant procedure with markedly reduced conditioning (RC-BMT). This type of transplant, sometimes referred to as mini-BMT, activates curative mechanisms 2,4, which for a number of diseases seems sufficient for cure. It avoids the severe organ toxicity of myeloablative radio-chemotherapy and the complications of profound neutropenia. Patients beyond the age limit of conventional BMT (50,60 yr) may therefore be candidates for this type of transplant as well as patients which because of other medical conditions or the type of disease for which the transplant is needed are poor candidates for CC-BMT. The procedure can be performed in an outpatient setting. The resulting cost reduction should contribute to making allogenic BMT more readily available. This review describes basic concepts and procedures involved in RC-BMT and summarizes preliminary results obtained with RC-BMT in different transplant centers. [source]


Cardiovascular risk of rosiglitazone: another perspective

JOURNAL OF PHARMACY AND PHARMACOLOGY: AN INTERNATI ONAL JOURNAL OF PHARMACEUTICAL SCIENCE, Issue 12 2008

Rosiglitazone is an effective therapy for type 2 diabetes although concerns have grown about the incidence of oedema and cardiovascular adverse events in patients treated with the drug. The following review was conducted to evaluate further and complement the evidence linking rosiglitazone with an increased risk for cardiovascular adverse events by examining trials and case reports not included in recent meta-analyses. Rosiglitazone-related publications describing case reports and prospective and retrospective cohort analyses were identified using MEDLINE and EMBASE, from July 1999 to July 2007. Relevant reports cited in these publications were also obtained. A recently-published meta-analysis and a double-blind, randomized, placebo-controlled trial were also reviewed. This review of 20 case reports and 10 uncontrolled studies supports the need for added vigilance when prescribing rosiglitazone to patients for the treatment of type 2 diabetes who may be at risk for congestive heart failure. Clinical data from numerous case reports and uncontrolled studies suggested that patients receiving rosiglitazone should be monitored for the development of weight gain or oedema. Prudence should be observed in patients with a history or risk factors for congestive heart failure as they may be poor candidates for rosiglitazone therapy. [source]

THE LARYNGOSCOPE, Issue 3 2010
Tim A. Iseli MBBS
Abstract Objectives/Hypothesis: Determine outcomes associated with nerve grafting versus static repair following facial nerve resection. Study Design: Retrospective chart review. Methods: Charts from 105 patients who underwent facial nerve reconstruction between January 1999 and January 2009 were reviewed. The majority had parotid malignancy (78.1%), most commonly squamous cell carcinoma (50.5%). Patients underwent static (n = 72) or dynamic (n = 33) reconstruction with nerve grafting. Facial nerve function was measured using the House-Brackmann (H-B) scale. Results: Patients receiving static reconstruction were on average 10.3 years older (P = .002). Mean overall survival for tumor cases was 61.9 months; parotid squamous cell carcinoma was associated with worse prognosis (P = .10). Median follow-up was 16.1 months (range, 4,96.1 months). Most (97%) patients receiving a nerve graft had some return of function at a median of 6.2 months postoperatively (range, 4,9 months) and the majority (63.6%) had good function (H-B score ,4). Patients having static reconstruction (29.2%) were more likely to have symptomatic facial palsy than those having a nerve graft (15.2%, P = .12). Conclusions: Where possible, nerve grafting is the preferred method of facial nerve reconstruction. Although elderly patients with parotid malignancy have traditionally been considered poor candidates for nerve grafting, we demonstrate good results within 9 months of facial nerve repair even with radiotherapy, the use of long grafts (>6 cm), and prolonged preoperative dysfunction.

Background: Although elderly patients with thoracic disease were considered to be poor candidates for thoracotomy before, recent advances in preoperative and postoperative care as well as surgical techniques have improved outcomes of thoracotomies in this patient group. The aim of this study was to investigate surgical risk factors and results in elderly patients (aged ,70 years) with thoracic empyema. Methods: Seventy-one elderly patients with empyema thoracis were enrolled and evaluated from July 2000 to April 2003. The following characteristics and clinical data were analysed: age, sex, aetiology of empyema, comorbid diseases, preoperative conditions, postoperative days of intubation, length of hospital stay after surgery, complications and mortality. Results: Surgical intervention, including total pneumonolysis and evacuation of the pleura empyema cavity, was carried out in all patients. Possible influent risk factors on the outcome were analysed. The sample group included 54 men and 17 women with an average age of 76.8 years. The causes of empyema included parapneumonic effusion (n = 43), lung abscess (n = 8), necrotizing pneumonitis (n = 8), malignancy (n = 5), cirrhosis (n = 2), oesophageal perforation (n = 2), post-traumatic empyema (n = 2) and post-thoracotomy complication (n = 1). The 30-day mortality rate was 11.3% and the in-hospital mortality rate was 18.3% (13 of 71). Mean follow up was 9.4 months and mean duration of postoperative hospitalization was 35.8 days. Analysis of risk factors showed that patients with necrotizing pneumonitis or abscess had the highest mortality rate (10 of 18, 62.6%). The second highest risk factor was preoperative intubation or ventilator-dependency (8 of 18, 44.4%). Conclusion: This study presents the clinical features and outcomes of 71 elderly patients with empyema thoracis who underwent surgical treatment. The 30-day surgical mortality rate was 11.3%. Significant risk factors in elderly patients with empyema thoracis were necrotizing pneumonitis, abscess and preoperative intubation/ventilation. This study also suggested that surgical treatment of empyema thoracic in elderly patients is recommended after failed conservative treatment because of the acceptably postoperative complication and mortality rate.

Treatment options for muscle-invasive urothelial cancer for patients who were not eligible for cystectomy or neoadjuvant chemotherapy with methotrexate, vinblastine, doxorubicin, and cisplatin

CANCER, Issue 10 2008
Report of Southwest Oncology Group Trial 873
Abstract BACKGROUND. Many patients with invasive urothelial cell cancer are poor candidates for cisplatin-based chemotherapy, and many are high risk for cystectomy. Southwest Oncology Group Trial 8733 was designed to address treatment for such patients. METHODS. Eligible patients had primary or recurrent muscle-invasive disease with transitional cell or squamous cell histology, a performance status from 0 to 2, no extrapelvic disease, a life expectancy >3 months, and adequate hematologic function. The treating clinician assigned patients to operable or inoperable groups. All patients received 2 cycles of 5-fluorouracil (5-FU) at a dose of 1000mg/m2 per day × 4 starting concurrently with radiation at a dose of 200 centigrays per day × 10 each cycle. After 2 cycles, operable patients with positive biopsies underwent cystectomy, and patients with negative biopsies received a third cycle of chemoradiotherapy. Patients in the inoperable group received 3 cycles without interim biopsy. RESULTS. Eighteen of 24 eligible patients in the operable group were evaluable for response. Five patients had a complete response (CR), 9 patients had stable disease, 1 patient had progressive disease, and 3 patients were not assessable. The median progression-free survival was 10 months (95% confidence interval [95% CI], 4,14 months), and the median overall survival was 18 months (95% CI, 7,28 months). In the inoperable group, 35 of 37 eligible patients were evaluable for response with 17 CRs (49%; 95% CI, 31%,66%). The median progression-free survival was 13 months (95% CI, 10,17 months), and the median overall survival was 20 months (95% CI, 11,53 months). There were no episodes of grade 4 toxicity. CONCLUSIONS. In the current study, the combination of 5-FU and radiation was found to be tolerated well by patients with numerous comorbidities who could not tolerate cisplatin-based therapy or cystectomy.

Subconjunctival injection of bevacizumab (Avastin®) for corneal neovascularization

ACTA OPHTHALMOLOGICA, Issue 2009
MF DE LA PAZ
Purpose to study the effects of subconjunctival injection of Bevacizumab on corneal neovascularization. Methods Prospective interventional case series on 7 eyes of 7 patients who underwent subconjunctival injection with Bevacizumab. The following parameters were studied pre-op, at 1 week, 30, 60 and 90 days post-op: UCVA, BCVA, pachymetry with OCT, slit lamp examination and photographic imaging. Conjunctival impression cytology pre-op at 1 week and 9o days was done and complications were also noted. Results Pre-op diagnoses were: herpetic leucoma (4 eyes), chemical burn (2 eyes), neurotrofic keratopathy (1 eye). An informed off-label consent form prior to procedure was signed. 1.25 mg of subconjunctival Bevacizumab was injected nearest the area affected. Mean preoperative UCVA and BCVA were 0.86 and 0.44 LogMar units, improved to 0.61 and 0.26 LogMar units at 90 days post-op, respectively. Central and peripheral pachymetry improved from 532 and 623 microns pre-op, to 529 and 619 microns at 90 days post-op, respectively. All slit lamp findings and photographic imaging showed a clear regression of superficial and deep stromal corneal vascularization, with clearing of lipid deposits around the affected areas. No toxic effects were noted on conjunctival impression cytology. Conclusion Subconjunctival injection of Bevacizumab is a safe and effective procedure for the regression of superficial and deep corneal neovascularization. It may be a good alternative for patients prior to performing an optical keratoplasty or for those who are poor candidates for the same. [source]
