To assess the safety and efficacy of extracorporeal shockwave myocardial revascularization (ESMR) therapy in treating patients with refractory angina pectoris. A single-arm multicenter prospective trial to assess safety and efficacy of the ESMR therapy in patients with refractory angina (class III/IV angina) was performed. Screening exercise treadmill tests and pharmacological single-photon emission computed tomography (SPECT) were performed for all patients to assess exercise capacity and ischemic burden. Patients were treated with 9 sessions of ESMR to ischemic areas over 9 weeks. Efficacy end points were exercise capacity by using treadmill test as well as ischemic burden on pharmacological SPECT at 4 months after the last ESMR treatment. Safety measures included electrocardiography, echocardiography, troponin, creatine kinase, and brain natriuretic peptide testing, and pain questionnaires. Fifteen patients with medically refractory angina and no revascularization options were enrolled. There was a statistically significant mean increase of 122.3±156.9 seconds (38% increase compared with baseline; P=.01) in exercise treadmill time from baseline (319.8±157.2 seconds) to last follow-up after the ESMR treatment (422.1±183.3 seconds). There was no improvement in the summed stress perfusion scores after pharmacologically induced stress SPECT at 4 months after the last ESMR treatment in comparison to that at screening; however, SPECT summed stress score revealed that untreated areas had greater progression in ischemic burden vs treated areas (3.69±6.2 vs 0.31±4.5; P=.03). There was no significant change in the mean summed echo score from baseline to posttreatment (0.4±5.1; P=.70). The ESMR therapy was performed safely without any adverse events in electrocardiography, echocardiography, troponins, creatine kinase, or brain natriuretic peptide. Pain during the ESMR treatment was minimal (a score of 0.5±1.2 to 1.1±1.2 out of 10). In this multicenter feasibility study, ESMR seems to be a safe and efficacious treatment for patients with refractory angina pectoris. However, larger sham-controlled trials will be required to confirm these findings. Copyright © 2014 Mayo Foundation for Medical Education and Research. Published by Elsevier Inc.

Acalabrutinib, a selective Bruton tyrosine kinase (BTK) inhibitor, was granted accelerated approval by the FDA on 31 October 2017 for the treatment of patients with mantle cell lymphoma (MCL) who have received at least one prior therapy. Areas covered: This narrative review provides an overview of acalabrutinib, its use in clinical practice and potential future developments. Expert commentary: BTK inhibitors have demonstrated efficacy in patients with relapsed or refractory MCL. To prepare patients for therapy, all preexisting infections should be diagnosed and treated, and infection prophylaxis undertaken. Serious adverse reactions are rare with acalabrutinib; however, patients should be made aware of common adverse events such as headaches, which usually resolve within one month without medical treatment. Interaction with other drugs appears to be less of an issue with acalabrutinib than with ibrutinib; however, patients receiving acalabrutinib therapy must be advised not to take any additional medications without first consulting with their treating physician. A key unmet medical need is treatment options for patients in whom BTK inhibitors are discontinued, because of either intolerance or refractory disease. Patients not tolerating ibrutinib could be switched to acalabrutinib, which has improved selectivity and increased tolerability. First-line treatment with acalabrutinib is being investigated.

Patients with burning mouth syndrome (BMS) report burning sensation and pain involving the tongue and oral mucosa without any apparent medical or dental cause. The pathogenesis of this syndrome remains unclear and there is currently no standard treatment. BMS is, therefore, often misdiagnosed and its management is complex. This lack of clinical expertise may result in decreased health-related quality of life and increased psychological distress among patients with BMS. The present case report involves a 77-year-old female patient with BMS refractory to conventional treatment with nerve block and medication, who was successfully treated with duloxetine. Duloxetine may become a new therapeutic option in the management of BMS. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Occipital neuralgia (ON) is a disorder characterized by sharp, electrical, paroxysmal pain, originating from the occiput and extending along the posterior scalp, in the distribution of the greater, lesser, and/or third occipital nerve. Occipital nerve stimulation (ONS) constitutes a promising therapy for medically refractory ON because it is reversible with minimal side effects and has shown continued efficacy with long-term follow-up. To conduct a systematic literature review and provide treatment recommendations for the use of ONS for the treatment of patients with medically refractory ON. A systematic literature search was conducted using the PubMed database and the Cochrane Library to locate articles published between 1966 and April 2014 using MeSH headings and keywords relevant to ONS as a means to treat ON. A second literature search was conducted using the PubMed database and the Cochrane Library to locate articles published between 1966 and June 2014 using MeSH headings and keywords relevant to interventions that predict response to ONS in ON. The strength of evidence of each article that underwent full text review and the resulting strength of recommendation were graded according to the guidelines development methodology of the American Association of Neurological Surgeons/Congress of Neurological Surgeons Joint Guidelines Committee. Nine studies met the criteria for inclusion in this guideline. All articles provided Class III Level evidence. Based on the data derived from this systematic literature review, the following Level III recommendation can be made: the use of ONS is a treatment option for patients with medically refractory ON.

OBJECTIVE The aim of this study was to investigate long-term seizure outcome, rate of reoperation, and postoperative neuropsychological performance following selective amygdalohippocampectomy (SelAH) or anterior temporal lobectomy (ATL) in pediatric patients with medically refractory temporal lobe epilepsy (TLE). METHODS The authors performed a retrospective review of cases of medically refractory pediatric TLE treated initially with either SelAH or ATL. Standardized pre- and postoperative evaluation included seizure charting, surface and long-term video-electroencephalography, 1.5-T MRI, and neuropsychological testing. RESULTS A total of 79 patients treated initially with SelAH (n = 18) or ATL (n = 61) were included in this study, with a mean follow-up of 5.3 ± 4 years (range 1-16 years). The patients' average age at initial surgery was 10.6 ± 5 years, with an average surgical delay of 5.7 ± 4 years between seizure onset and surgery. Seizure freedom (Engel I) following the initial operation was significantly more likely following ATL (47/61, 77%) than SelAH (8/18, 44%; p = 0.017, Fisher's exact test). There was no statistically significant difference in the proportion of patients with postoperative neuropsychological deficits following SelAH (8/18, 44%) or ATL (21/61, 34%). However, reoperation was significantly more likely following SelAH (8/18, 44%) than after ATL (7/61, 11%; p = 0.004) and was more likely to result in Engel I outcome for ATL after failed SelAH (7/8, 88%) than for posterior extension after failed ATL (1/7, 14%; p = 0.01). Reoperation was well tolerated without significant neuropsychological deterioration. Ultimately, including 15 reoperations, 58 of 79 (73%) patients were free from disabling seizures at the most recent follow-up. CONCLUSIONS SelAH among pediatric patients with medically refractory unilateral TLE yields significantly worse rates of seizure control compared with ATL. Reoperation is significantly more likely following SelAH, is not associated with incremental neuropsychological deterioration, and frequently results in freedom from disabling seizures. These results are significant in that they argue against using SelAH for pediatric TLE surgery.

Chronic refractory low back and lower extremity pain is frustrating to treat. Percutaneous adhesiolysis and spinal endoscopy are techniques which can treat chronic refractory low back and lower extremity pain.Percutaneous adhesiolysis is performed by placing the catheter into the tissue plane at the ventrolateral aspect of the foramen so that medications can be injected. Adhesiolysis is used both for pain caused by scarring which is not resistant to catheter placement and other sources of pain, including inflammation in the absence of scarring.Mechanical lysis of scars with a catheter may or may not be necessary for percutaneous adhesiolysis to be effective. Spinal endoscopy allows direct visualization of the epidural space and has the possibility to use laser energy to treat pathology. A systematic review of the effectiveness of percutaneous adhesiolysis and spinal endoscopic adhesiolysis to treat chronic refractory low back and lower extremity pain. To evaluate and update the effectiveness of percutaneous adhesiolysis and spinal endoscopic adhesiolysis to treat chronic refractory low back and lower extremity pain. The available literature on percutaneous adhesiolysis and spinal endoscopic adhesiolysis in treating persistent low back and leg pain was reviewed. The quality of each article used in this analysis was assessed. The level of evidence was classified on a 5-point scale from strong, based upon multiple randomized controlled trials to weak, based upon consensus, as developed by the U.S. Preventive Services Task Force (USPSTF) and modified by ASIPP. Data sources included relevant literature identified through searches of PubMed and EMBASE from 1966 to September 2015, and manual searches of the bibliographies of known primary and review articles. Pain relief of at least 50% and functional improvement of at least 40% were the primary outcome measures. Short-term efficacy was defined as improvement of 6 months or less; whereas, long-term efficacy was defined more than 6 months. For this systematic review, 45 studies were identified. Of these, for percutaneous adhesiolysis there were 7 randomized controlled trials and 3 observational studies which met the inclusion criteria. For spinal endoscopy, there was one randomized controlled trial and 3 observational studies. Based upon 7 randomized controlled trials showing efficacy, with no negative trials, there is Level I or strong evidence of the efficacy of percutaneous adhesiolysis in the treatment of chronic refractory low back and lower extremity pain. Based upon one high-quality randomized controlled trial, there is Level II to III evidence supporting the use of spinal endoscopy in treating chronic refractory low back and lower extremity pain. The evidence is Level I or strong that percutaneous adhesiolysis is efficacious in the treatment of chronic refractory low back and lower extremity pain. Percutaneous adhesiolysis may be considered as a first-line treatment for chronic refractory low back and lower extremity pain. The evidence is Level II to III that spinal endoscopy is effective in the treatment of chronic refractory low back and lower extremity pain.

Objective: To evaluate the long-term benefit and safety of everolimus for the treatment of medically refractory epilepsy in patients with tuberous sclerosis complex (TSC). Methods: Everolimus was titrated over 4 weeks and continued an additional 8 weeks in a prospective, open-label, phase I/II clinical trial design. Participants demonstrating initial benefit continued treatment until study completion (48 months). The primary endpoint was percentage of patients with a ≥50% reduction in seizure frequency compared to baseline. Secondary endpoints assessed absolute seizure frequency, adverse events (AEs), behavior, and quality of life. Results: Of the 20 participants who completed the initial study phase, 18 continued extended treatment. Fourteen of 18 (78%) participants completed the study, all but 1 of whom reported ≥50% reduction in seizure frequency at 48 months. All participants reported at least 1 AE, the vast majority (94%) of which were graded mild or moderate severity. Improvements in behavior and quality of life were also observed, but failed to achieve statistical significance at 48 months. Conclusions: Improved seizure control was maintained for 4 years in the majority of patients with TSC with medically refractory epilepsy treated with everolimus. Long-term treatment with everolimus is safe and well-tolerated in this population. Everolimus may be a therapeutic option for refractory epilepsy in TSC. Classification of evidence: This study provides Class IV evidence that for patients with TSC with medically refractory epilepsy everolimus improves seizure control. PMID:27815402

The management of refractory glaucoma is a challenging task for any glaucoma surgeon. This study is aimed to evaluate the efficacy of Ahmed Glaucoma Valve implantation in refractory glaucomas in South-West Ethiopia. A retrospective review was conducted on the charts of consecutive patients treated with Ahmed glaucoma valve implantation at Jimma University Specialized Hospital between August 2012 and August 2014. Success was defined as Intraocular Pressure (IOP) less than 22 mm Hg and greater than 5mm Hg at 6 months, with at least 30% reduction from baseline, without medical therapy (complete success) or either with or without medication (qualified successes). A total of 12 eyes of 11 patients were included. The mean age of patients was 40.7 (SD= 19.0) years; 63.6% of them were males. The main types of glaucoma were pseudoexfoliative (3 eyes), uveitic (2 eyes), chronic angle closure (2 eyes) and Juvenile Open Angle (JOAG) (2 eyes). The mean IOP was reduced from preoperative level (32.75±7.14 mmHg) to (15.75 ±4.35 mmHg) at six postoperative months, (P<0.001); 66.7% eyes had complete successes while 83.3% had qualified success. Intra-operative complications were encountered in 2(16.7%) eyes, while 5/12 (41.7%) eyes had post-operative complications-hypotony (one with choroidal effusion) and progression of cataract in 2 eyes each. Hypertensive phase was diagnosed in 2(16.7%) eyes. The Ahmed glaucoma valve implant appears to be effective and relatively safe for treating complicated glaucomas with success rate comparable with those reported from other studies.

Schizophrenia has a 1% prevalence in the population; 30% of these patients are treatment refractory. Clozapine is the only drug licensed to treat treatment refractory psychosis, but concerns about potential adverse effects result in only a proportion of eligible patients being treated. Although a well-documented neutropenia risk is mitigated by routine blood testing, cardiac toxicity is a commonly cited reason to discontinue clozapine treatment. However, there is little data on the real-life cardiac outcomes in those receiving clozapine treatment. Retrospective review of electrocardiogram, echocardiogram, and clinical outcomes in 39 inpatients with treatment-refractory schizophrenia, treated with clozapine and other antipsychotic medication, referred for cardiology opinion. Commonest reasons for referral were development of left ventricular (LV) impairment or sinus tachycardia with normal LV function. Patients were reviewed by a range of cardiologists, receiving varied interventions.Median LV ejection fraction in the clozapine group was normal (52%). Serial echocardiograms demonstrated that clozapine-treated patients with LV impairment had no change in LV ejection fraction over a 4-month follow-up. Left ventricular ejection fraction did not differ between patients treated with clozapine and other antipsychotics. However, over an 11-year follow-up period, 48% of patients had discontinued clozapine treatment. This naturalistic study demonstrates that clozapine is not associated with significant cardiac mortality or morbidity. There is a real need for multidisciplinary working between specialist cardiologists and psychiatrists caring for these complex patients to facilitate optimal long-term physical and mental health outcomes.

Overdose of cardiovascular medications is increasingly associated with morbidity and mortality. We present a case of substantial atenolol, chlorthalidone, and lisinopril overdose treated by multiple modalities with an excellent outcome. Aggressive medical intervention did not provide sufficient hemodynamic stability in this patient with refractory cardiogenic and distributive shock. Impella® percutaneous left ventricular assist device and extracorporeal membrane oxygenation provided support while the effects of the overdose subsided. We present concentrations demonstrating removal of atenolol with continuous venovenous hemodiafiltration. This is the first report of esophagogastroduo denoscopy decontamination of this overdose with a large pill fragment burden.

Treatment of Patellar Tendinopathy Refractory to Surgical Management Using Percutaneous Ultrasonic Tenotomy and Platelet-Rich Plasma Injection: A Case Presentation.

2015-12-01

Chronic proximal patellar tendinopathy is a common condition in sports medicine that may be refractory to nonoperative treatments, including activity modification, medications, and comprehensive rehabilitation. Percutaneous ultrasonic tenotomy is a recently developed technique designed to cut and debride tendinopathic tissue, thus promoting pain relief and functional recovery. We present a case of a collegiate athlete with chronic proximal patellar tendinopathy who was effectively treated with percutaneous ultrasonic tenotomy after not responding to extensive nonoperative treatment, surgical debridement, and platelet-rich plasma injections. Percutaneous ultrasonic tenotomy can be considered as a treatment option in patients presenting with refractory proximal patellar tendinopathy, including those who do not respond to previous operative intervention.

Tourette syndrome (TS) is a neuropsychiatric disorder presenting with motor and/or sonic tics associated with frontostriatal dysfunction. This study provided pilot data of the neuropsychological safety of bilateral thalamic deep brain stimulation (DBS) to treat medication-refractory TS in adults. This study used a repeated-measures design with pretest and 3-month follow-up from start of continuous bilateral DBS. Five male patients underwent DBS surgery for medically refractory TS. Repeated-measures ANOVA was used to evaluate for any change in neuropsychological test scores, employing a false discovery rate. Outcome measures included 14 neuropsychological tests assessing psychomotor speed, attention, memory, language, visuoconstructional, and executive functions, as well as subjective mood ratings of depression and anxiety. Average age was 28.2 years (SD = 7.5) with 12-17 years of education. Participants were disabled by tics, with a tic frequency of 50-80 per minute before surgery. At baseline, subjects' cognitive function was generally average, although mild deficits in sequencing and verbal fluency were present, as were clinically mild obsessive-compulsive symptoms. At 3 months of continuous DBS (5 months after implantation), 3 of 5 participants had clinical reductions in motor and sonic tics. Cognitive scores generally remained stable, but declines of moderate to large effect size (Cohen's d > 0.6) in verbal fluency, visual immediate memory, and reaction time were observed. Fewer symptoms of depression and anxiety, as well as fewer obsessions and compulsions, were reported after 3 months of continuous high-frequency DBS. Bilateral centromedian-parafascicular thalamic DBS for medically refractory TS shows promise for treatment of medically refractory TS without marked neuropsychological morbidity. Symptoms of depression and anxiety improved. © 2014 International Neuromodulation Society.

A UK trial-based cost--utility analysis of transmyocardial laser revascularization compared to continued medical therapy for treatment of refractory angina pectoris.

Transmyocardial laser revascularization (TMLR) is used to treat patients with refractory angina considered unsuitable for conventional forms of revascularization. Using patient specific data from a single centre UK randomised-controlled trial, we aimed to determine whether, from a UK National Health Service (NHS) perspective, TMLR plus standard medical management is cost-effective when compared with standard medical management alone. One hundred and eighty-eight patients assessed as having refractory angina, and not suitable for conventional forms of revascularization were randomized to receive TMLR and medical management (94) or medical management alone (94). Costs to the UK NHS of TMLR (where appropriate), and all secondary sector health care contacts and cardiac-related medication in the 12 months following randomization, were collected. Patient utility as measured using the EuroQol EQ-5D questionnaire was combined with 12-month survival data to generate quality adjusted life years (QALYs). The mean cost per patient over the year from hospitalization for TMLR was 11,470 pounds sterling and for medical management alone was 2586 pounds sterling, giving a cost difference of 8901 pounds sterling (95% confidence interval (CI) 7502 pounds sterling--10,008 pounds sterling: P < 0.0001). The mean QALY difference, in favour of TMLR was 0.039 (95% CI -0.033 to 0.113: P = 0.268). This gives an incremental cost per QALY of over 228,000 pounds sterling. Analysis of stochastic uncertainty and of sensitivity to gross changes in key parameters consistently produces very high costs per QALY. The policy implications are clear: for such patients TMLR is an inefficient use of UK health service resources. This conclusion would not be changed by considerable improvements in effectiveness or reductions in cost.

Gastrointestinal involvement of Behçet's syndrome is usually treated with glucocorticoids, 5-aminosalicylic acid compounds and azathioprine. However, some patients are refractory to these conventional therapy modalities. In this paper we report our experience on 13 patients with gastrointestinal involvement of Behçet's syndrome who were refractory to the conventional therapy and who were treated with TNF-alpha antagonists and/or thalidomide. We reviewed the charts of our Behçet's syndrome patients with gastrointestinal involvement and identified those who were treated with TNF-alpha antagonists and/or thalidomide. Demographic features, previous and concomitant drugs, previous surgery, time to remission and duration of remission were tabulated. We also performed a systematic review of publications on gastrointestinal involvement of Behçet's syndrome patients treated with TNF-alpha antagonists and/or thalidomide. Among our 64 patients with gastrointestinal involvement of Behçet's syndrome, we identified 13 (20%) (7 women, 6 men, mean age 27.4±9.4) who had been treated with TNF-alpha antagonists and/or thalidomide. Their previous medications were glucocorticoids (13/13), azathioprine (13/13), 5-aminosalicylic acid derivatives (3/13) and budesonide (1/13). Clinical and endoscopic remission was obtained in 10 patients. One patient died with sepsis. The systematic literature search revealed 91 cases who had used TNF-alpha antagonists and 15 who had used thalidomide. Among the patients who had received TNF-alpha antagonists, clinical remission was obtained in 47/91 patients (51%), while endoscopic remission was observed in 21/46 (45%) who had a control colonoscopy. One fifth of our Behçet's syndrome patients with gastrointestinal involvement were refractory to conventional treatment modalities. Remission was obtained with TNF-alpha antagonists and/or thalidomide in about 75% of the cases.

Propofol-Based Palliative Sedation to Treat Antipsychotic-Resistant Agitated Delirium.

PubMed

Covarrubias-Gómez, Alfredo; López Collada-Estrada, Maria

Delirium is a common problem in terminally ill patients that is associated with significant distress and, hence, considered a palliative care emergency. The three subtypes of delirium are hyperactive, hypoactive, and mixed, depending on the level of psychomotor activity and arousal disturbance. When agitated delirium becomes refractory in the setting of imminent dying, the agitation may be so severe that palliative sedation (PS) is required. Palliative sedation involves the administration of sedative medications with the purpose of reducing level of consciousness for patients with refractory suffering in the setting of a terminal illness. Propofol is a sedative that has a short duration of action and a very rapid onset. These characteristics make it relatively easy to titrate. Reported doses range from 50 to 70 mg per hour. The authors present a case of antipsychotic-resistant agitated delirium treated with a propofol intravenous infusion.

[The last phase in the progressive neoplasic disease: care at the end-of-life, refractory symptoms and sedation].

End-of-life is one of the most stressful phases during course of a neoplasic disease. Frequently, death of patients with cancer comes after a continuous and progressive physical impairment. As death approaches, the medical team might redefine outcomes and treat as priority symptoms and relief suffering. That care encompasses the physical, psychological, social, spiritual, and existential needs of patients and their families. However, symptoms are frequently observed that are intolerable for the patient and which do not respond to usual palliative measures. The intolerable nature and being refractory to treatment indicates to the health-care team, on many occasions, the need for sedation of the patient. The medical team can take comfort in the knowledge that they did their best to provide safe passage to all their patients and that, although they did not always cure them, the patients often were healed.

Despite medical therapy, 30% of patients with ulcerative colitis (UC) need to undergo surgery. Around 50% of patients with proctocolectomy with ileal pouch-anal anastomosis (IPAA) develop complications of the pouch. Clinical evidence for the use of infliximab (IFX) in refractory pouchitis is limited. The aim of this study was to report efficacy of IFX in these patients. A retrospective, multicenter study was designed. Patients older than 18 years with chronic refractory pouchitis treated with IFX (5 mg/kg) were included. Short-term IFX efficacy was evaluated at week 8 and mid-term efficacy at weeks 26 and 52. Complete response was defined as cessation of diarrhea and urgency and partial response as marked clinical improvement but persisting symptoms. The modified Pouchitis Disease Activity Index (mPDAI) without endoscopy was calculated when available. Thirty-three consecutive UC patients with chronic refractory pouchitis were included (18 male, mean age 45 years, range 21-67). At week 8, 21% patients achieved complete response and 63% showed partial clinical response. At weeks 26 and 52, 33% and 27% achieved complete response and 33% and 18% showed partial clinical response, respectively. Thirteen patients (39%) withdrew treatment (four for lack of efficacy, four for loss of response and five for adverse events).

Electroconvulsive therapy (ECT) raises the seizure threshold. This physiological change may benefit patients with seizure disorders. Whereas ECT has recently been used to terminate medication-refractory status epilepticus, there is little current literature on its planned administration as a specific maintenance treatment for medication-refractory epilepsy. We used maintenance ECT to treat an 18-year-old man with a long-standing generalized tonic-clonic seizure disorder who had shown poor response to several antiepileptic drugs administered in combination with antiepileptic medication compliance confirmed through drug level monitoring. A total of 52 ECTs were administered across nearly 20 months at a mean frequency of once in nearly 12 days. From the very outset, ECT dramatically decreased the frequency of spontaneous seizures from approximately 6 to 24 per week at baseline to approximately 1 to 2 per week after ECT initiation. The efficacy of maintenance ECT in spontaneous seizure prophylaxis was greater when the ECT treatment interval was narrower. Improvement with ECT was associated with improved behavior and improved psychosocial functioning on clinical report. No cognitive or other adverse effects were reported or clinically ascertained. The ECT charge administered at the last 10 treatment sessions was 1434 millicoulombs. This is probably the highest electrical stimulus dose recorded in literature. Maintenance ECT may reduce the frequency of breakthrough seizures in patients with seizure disorder that is inadequately responsive to antiepileptic medication regimes. Very high ECT seizure thresholds may be observed when many antiepileptic drugs are concurrently administered in high doses.

Refractory overactive bladder: Beyond oral anticholinergic therapy

PubMed Central

Glinski, Ronald W.; Siegel, Steven

Objectives: In this review, we discuss the treatment of refractory overactive bladder (OAB) that has not adequately responded to medication therapy and we propose an appropriate care pathway to the treatment of OAB. We also attempt to address the cost of OAB treatments. Materials and Methods: A selective expert review of the current literature on the subject of refractory OAB using MEDLINE was performed and the data is summarized. We also review our experience in treating refractory OAB. The role and outcomes of various treatment options for refractory OAB are discussed and combined therapy with oral anticholinergics is explored. Emerging remedies including intravesical botulinum toxin injection and pudendal neuromodulation are also reviewed, along with conventional surgical options. Results: In general behavioral therapy, pelvic floor electrical stimulation, magnetic therapy and posterior tibial nerve stimulation (PTNS), have shown symptom decreases in 50-80% of patients with OAB. Depending on the study, combination therapy with oral anticholinergics seems to improve efficacy of behavioral therapy and PTNS in approximately 10-30%. In multicenter, long-term randomized controlled trials, sacral neuromodulation has been shown to improve symptoms of OAB and OAB incontinence in up to 80% of the patients treated. Studies involving emerging therapies such as pudendal serve stimulation suggest that there may be a 15-20% increase in efficacy over sacral neuromodulation, but long-term studies are not yet available. Another emerging therapy, botulinum toxin, is also showing similar success in reducing OAB symptoms in 80-90% of patients. Surgical approaches, such as bladder augmentation, are a last resort in the treatment of OAB and are rarely used at this point unless upper tract damage is a concern and all other treatment options have been exhausted. Conclusion: The vast majority of OAB patients can be managed successfully by behavioral options with or without anticholinergic medications. When those fail, neuromodulation or intravesical botulinum toxin therapies are successful alternatives for most of the remaining group. We encourage practitioners responsible for the care of OAB patients to gain experience with these options. More research is needed to assess the cost-effectiveness of various OAB treatments PMID:19675795

Early posttraumatic seizures may contribute to worsened outcomes after traumatic brain injury. Evidence to guide the evaluation and management of early posttraumatic seizures in children is limited. We undertook a survey of current practices of continuous electroencephalographic monitoring, seizure prophylaxis, and the management of early posttraumatic seizures to provide essential information for trial design and the development of posttraumatic seizure management pathways. Surveys were sent to site principal investigators at all 43 sites participating in the Approaches and Decisions in Acute Pediatric TBI trial at the time of the survey. Surveys consisted of 12 questions addressing strategies to 1) implement continuous electroencephalographic monitoring, 2) posttraumatic seizure prophylaxis, 3) treat acute posttraumatic seizures, 4) treat status epilepticus and refractory status epilepticus, and 5) monitor antiseizure drug levels. Institutions comprised a mixture of free-standing children's hospitals and university medical centers across the United States and Europe. Site principal investigators of the Approaches and Decisions in Acute Pediatric TBI trial. None. Continuous electroencephalographic monitoring was available in the PICU in the overwhelming majority of clinical sites (98%); however, the plans to operationalize such monitoring for children varied considerably. A similar majority of sites report that administration of prophylactic antiseizure medications is anticipated in children (93%); yet, a minority reports that a specified protocol for treatment of posttraumatic seizures is in place (43%). Reported medication choices varied substantially between sites, but the majority of sites reported pentobarbital for refractory status epilepticus (81%). The presence of treatment protocols for seizure prophylaxis, early posttraumatic seizures, posttraumatic status epilepticus, and refractory status epilepticus was associated with decreased reported medications (all p < 0.05). This study reports the current management practices for early posttraumatic seizures in select academic centers after pediatric severe traumatic brain injury. The substantial variation in continuous electroencephalographic monitoring implementation, choice of seizure prophylaxis medications, and management of early posttraumatic seizures across institutions was reported, signifying the areas of clinical uncertainty that will help provide focused design of clinical trials. Although sites with treatment protocols reported a decreased number of medications for the scenarios described, completion of the Approaches and Decisions in Acute Pediatric TBI trial will be able to determine if these protocols lead to decreased variability in medication administration in children at the clinical sites.

Burning mouth syndrome (BMS) is a medical condition that is often refractory to conventional diagnostic and therapeutic methods. Patients suffering from BMS can benefit from a biopsychosocial approach in a joint, medical-psychological consultation model. Such a consultation exists at Geneva University Hospitals, involving the collaboration of the maxillo-facial and oral surgery division and the division of liaison psychiatry and crisis intervention, in order to take into account the multiple factors involved in BMS onset and persistence. This article will describe BMS clinical presentation, and present an integrate approach to treat these patients.

To evaluate the safety and efficacy of the ultrasonic circular cyclo-coagulation procedure using high-intensity focused ultrasound by a miniaturized annular device containing 6 piezoceramic transducers in patients with refractory glaucoma. This was a prospective interventional noncomparative study of 20 eyes of 20 patients with refractory glaucoma. All eyes were treated with 6 activated transducers operating at 21 MHz. Ultrasound biomicroscopy and a complete ophthalmic examination were performed before the procedure and at 1 day, 1 week, and 1, 3, 6, and 12 months after the procedure. Primary outcomes were surgical success (defined as intraocular pressure (IOP) reduction from baseline ≥20% and IOP >5 mm Hg) at the last follow-up visit. Secondary outcomes were mean IOP at each follow-up visit compared to baseline, medication use, complications, and re-interventions. Intraocular pressure was significantly reduced (p<0.01) from a mean preoperative value of 36.4 ± 5.7 mm Hg to a mean postoperative value of 22.5 ± 10.3 mm Hg at 12 months. Four patients needed to be re-treated. The mean IOP reduction achieved was 38%. Surgical success was achieved in 13 of 20 eyes (65%). No major intraoperative or postoperative complications occurred. Ultrasonic circular cyclo-coagulation using high-intensity focused ultrasound delivered by a circular miniaturized device containing 6 piezoceramic transducers is an effective and well-tolerated method to reduce IOP in patients with refractory glaucoma.

Objective Primary platinum-resistant epithelial ovarian cancer (EOC) is an area of unmet medical need. There is limited evidence from small studies that platinum-based combinations can overcome “resistance” in a proportion of patients. We investigated the efficacy and toxicity of platinum-based combination chemotherapy in the platinum-resistant and platinum-refractory setting. Methods Epirubicin, cisplatin, and capecitabine (ECX) combination chemotherapy was used at our institution for the treatment of relapsed EOC. From the institutional database, we identified all patients with primary platinum-refractory or platinum-resistant relapse treated with ECX as second-line therapy between 2001 and 2012. We extracted demographic, clinical, treatment, and toxicity data and outcomes. We used logistic and Cox regression models to identify predictors of response and survival respectively. Results Thirty-four 34 patients (8 refractory, 26 resistant) were treated with ECX. Response Evaluation Criteria In Solid Tumors (RECIST) response rate was 45%, median progression-free survival (PFS) was 6.4 months, and overall survival (OS) was 10.6 months. Platinum-resistant patients had better outcomes than did platinum-refractory patients (response rate, 54% vs 0%, P = 0.047; PFS 7.2 vs 1.8 months, P < 0.0001; OS 14.4 vs 3 months, P < 0.001). In regression models, time to progression after first-line treatment and platinum-refractory status were the strongest predictors of response and PFS or OS, respectively. Patients with time to progression after first-line treatment longer than 3 months showed PFS and OS of 7.9 and 14.7 months, respectively. Toxicity was manageable, with only 13% of cycles administered at reduced doses. Conclusions Epirubicin, cisplatin, and capecitabine seems to be active in platinum-resistant relapsed EOC with manageable toxicity. Further prospective investigation of platinum-anthracycline combinations is warranted in patients who relapse 3 to 6 months after first-line platinum-taxane treatment. PMID:25962114

[Classical medications in the treatment of inflammatory bowel diseases].

PubMed

Duvnjak, Marko; Bilić, Ante; Barsić, Neven; Tomasić, Vedran; Stojsavljević, Sanja

2013-04-01

The treatment of inflammatory bowel diseases is complex and requires individual approach to every single patient. Traditionally, the approach is based on introduction of so called "classical" medication into the treatment regimen, from ones less potent and with fewer side effects to the ones more toxic but also therapeutically more effective. Aminosalicylates were the first choice of treatment for a long time. However, the role of aminosalicylates is becoming more and more diminished, although they are still the drug of choice in the treatment of mild to moderate ulcerative colitis. Corticosteroids are the therapy of choice in treatment of active IBD for achieving remission in moderate to severe disease. Azathioprine and 6- mercaptopurine belong to a group of thiopurines with an immunomodulatory effect which, in Crohn's disease as well as in ulcerative colitis, primarily have a role in a steroid dependant or steroid refractory type of disease and in maintenance of remission. Lately, early introduction of these medications is proposed to enhance the number of patients that remain in remission. Methotrexate is used for the therapy of active and relapsing Crohn's disease and represents an alternative in patients who do not tolerate or do not respond to azathioprine or 6-mercaptopurine therapy. Cyclosporine is used in treating steroid refractory ulcerative colitis and in some patients can postpone the need for colectomy. Antibiotics do not have a proven effect on the course of inflammatory bowel diseases and their primary role is to treat septic complications. Classic medications today represent a standard in the management of inflammatory bowel diseases, and the combination of the previously mentioned drugs often has a more potent effect on the course of the disease than any medication on its own and their combination is still an object of investigations and clinical studies.

Efficacy of CBD-enriched medical cannabis for treatment of refractory epilepsy in children and adolescents - An observational, longitudinal study.

PubMed

The objective of this observational study was to evaluate the efficacy of medical cannabis for the treatment of refractory epilepsy. Fifty-seven patients (age 1-20 years) with epilepsy of various etiologies were treated with Cannabis oil extract (CBD/THC ratio of 20:1) for at least 3 months (Median follow up time-18 months). Forty-Six Patients were included in the efficacy analysis. Average CBD dose was11.4 mg/kg/d. Twenty-six patients (56%) had ≤50% reduction in mean monthly seizure frequency. There was no statistically significant difference in response rate among various epilepsy etiologies, and cannabis strain used. Younger age at treatment onset (<10 years) and higher CBD dose (>11 mg/kg/d) were associated with better response to treatment. Adverse reactions were reported in 46% of patients and were the main reason for treatment cessation. Our results suggest that adding CBD-enriched cannabis extract to the treatment regimen of patients with refractory epilepsy may result in a significant reduction in seizure frequency according to parental reports. Randomized controlled trials are necessary to assess its true efficacy. Copyright © 2018 Elsevier B.V. All rights reserved.

Clinical and immunologic effects of faecal microbiota transplantation in a patient with collagenous colitis

One to six percent of patients with microscopic colitis are refractory to medical treatment. The effect of faecal microbiota transplantation (FMT) in active collagenous colitis (CC) has, to the best of our knowledge, never been reported before. Here, we report the effect of repeated FMT in a patient with CC. The patient presented with severe symptoms including profuse diarrhea and profound weight loss. Although she responded to budesonide in the beginning, she became gradually refractory to medical treatment, and was therefore treated with FMT. The patient remained in remission for 11 mo after the third faecal transplantation. The immunomodulatory effect of the therapy was evaluated using flow cytometry, which showed alterations in the profile of intraepithelial and lamina propria lymphocyte subsets after the second transplantation. Our observations indicate that FMT can have an effect in CC, which support the hypothesis that luminal factors, influencing the intestinal microbiota, are involved in the pathogenesis of CC.

Epilepsy is a chronic neurological disorder characterized by recurrent, unprovoked epileptic seizures. The majority of people given a diagnosis of epilepsy have a good prognosis, but 20-30 % will develop drug-resistant epilepsy. Vagus nerve stimulation (VNS) is a neuromodulatory treatment that is used as an adjunctive therapy for treating people with medically refractory epilepsy. It consists of chronic intermittent electrical stimulation of the vagus nerve, delivered by a programmable pulse generator (Neuro-Cybernetic Prosthesis). In 1997, the Food and Drug Administration approved VNS as adjunctive treatment for medically refractory partial-onset seizures in adults and adolescents. This article reviews the literature from 1988 to nowadays. We discuss thoroughly the anatomy and physiology of vagus nerve and the potential mechanisms of actions and clinical applications involved in VNS therapy, as well as the management, safety, tolerability and effectiveness of VNS therapy. VNS for partial seizures appears to be an effective and well tolerated treatment in adult and pediatric patients. People noted improvements in feelings of well-being, alertness, memory and thinking skills, as well as mood. The adverse effect profile is substantially different from the adverse effect profile associated with antiepileptic drugs, making VNS a potential alternative for patients with difficulty tolerating antiepileptic drug adverse effects. Despite the passing years and the advent of promising neuromodulation technologies, VNS remains an efficacy treatment for people with medically refractory epilepsy. Past and ongoing investigations in other indications have provided signals of the therapeutic potential in a wide variety of conditions.

Noninvasive Brain Stimulation: Challenges and Opportunities for a New Clinical Specialty.

Noninvasive brain stimulation refers to a set of technologies and techniques with which to modulate the excitability of the brain via transcranial stimulation. Two major modalities of noninvasive brain stimulation are transcranial magnetic stimulation (TMS) and transcranial current stimulation. Six TMS devices now have approved uses by the U.S. Food and Drug Administration and are used in clinical practice: five for treating medication refractory depression and the sixth for presurgical mapping of motor and speech areas. Several large, multisite clinical trials are currently underway that aim to expand the number of clinical applications of noninvasive brain stimulation in a way that could affect multiple clinical specialties in the coming years, including psychiatry, neurology, pediatrics, neurosurgery, physical therapy, and physical medicine and rehabilitation. In this article, the authors review some of the anticipated challenges facing the incorporation of noninvasive brain stimulation into clinical practice. Specific topics include establishing efficacy, safety, economics, and education. In discussing these topics, the authors focus on the use of TMS in the treatment of medication refractory depression when possible, because this is the most widely accepted clinical indication for TMS to date. These challenges must be thoughtfully considered to realize the potential of noninvasive brain stimulation as an emerging specialty that aims to enhance the current ability to diagnose and treat disorders of the brain.

Patient: Female, 60 Final Diagnosis: Hyponatremia due to secondary adrenal insufficiency Symptoms: prolonged general fatigue and anorexia Medication: — Clinical Procedure: Successfully treated by dexamethasone with sodium chloride Specialty: Nephrology Objective: Rare co-existance of disease or pathology Background: Patients who were surgically treated for Cushing’s syndrome postoperatively surrender to “primary” adrenal insufficiency. However, the preoperative over-secretion of cortisol or the postoperative administration of excessive glucocorticoids can cause “secondary” adrenal insufficiency, in which the prevalence of hyponatremia is usually lower than that of primary adrenal insufficiency. Case Report: A 60-year-old woman with a past medical history of Cushing’s syndrome developed hyponatremia with symptoms of acute glucocorticoid deficiency, such as prolonged general fatigue and anorexia, after upper respiratory tract infection. A decrease in the serum cortisol level and the lack of increase in the ACTH level, despite the increased demand for cortisol, enabled a diagnosis of “secondary” adrenal insufficiency. Although the initial fluid replacement therapy was not effective, co-administration of dexamethasone and sodium chloride quickly resolved her symptoms and ameliorated the refractory hyponatremia. Conclusions: In this case, the hypothalamic-pituitary axis of the patient was thought to have become suppressed long after the surgical treatment for Cushing’s syndrome. This case suggested a mechanism of refractory hyponatremia caused by secondary adrenal insufficiency, for which the administration of dexamethasone and sodium chloride exerted additional therapeutic efficacy.

Refractory pulmonary sarcoidosis - proposal of a definition and recommendations for the diagnostic and therapeutic approach.

PubMed

2016-03-01

Patients with sarcoidosis undergo spontaneous remission or may be effectively controlled with glucocorticoids alone in many cases. Progressive and refractory pulmonary sarcoidoisis constitute more than 10% of patients seen at specialized centers. Pulmonary fibrosis and associated complications, such as infections and pulmonary hypertension are leading causes of mortality. No universal definition of refractoriness exists, we therefore propose classifying patients as having refractory disease when the following criteria are fulfilled: (1) progressive disease despite at least 10 mg of prednisolone or equivalent for at least three months and need for additional disease-modifying anti-sarcoid drugs due to lack of efficacy, drug toxicity or intolerability and (2) treatment started for significant impairment of life due to progressive pulmonary symptoms. Both criteria should be fulfilled. Treatment options in addition to or instead of glucocorticoids for these patients include second- (methotrexate, azathioprine, leflunomide) and third-line agents (infliximab, adalimumab). Other immunmodulating agents can be used, but the evidence is very limited. Newer agents with anti-fibrotic properties, such as pirfenidone or nintedanib, might hold promise also for the pulmonary fibrosis seen in sarcoidosis. Treating physicians have to actively look for potentially treatable complications, such as pulmonary hypertension, cardiac disease or infections before patients should be classified as treatment-refractory. Ultimately, lung transplantation has to be considered as treatment option for patients not responding to medical therapy. In this review, we aim to propose a new definition of refractoriness, describe the associated clinical features and suggest the therapeutic approach.

Abstract Refractory glaucoma refers to uncontrolled intraocular pressure (IOP) despite anti-glaucoma medication and surgical treatment, which remains a challenge to be treated. The objective of this study is to evaluate and statistically compare the clinical efficacy between endoscopic cyclophotocoagulation (ECP) and alternative surgical techniques in the treatment of refractory glaucoma in this article, as a meta-analysis. Data sources are China Biomedical Database (Sinomed, online version), China National Knowledge Infrastructure (CNKI), Cqvip, Wanfang database, and PubMed. The randomized controlled trial (RCT) and case–control study literatures evaluating the clinical efficacy between ECP and other surgical techniques were searched electronically from public databases. The methodology quality of the retrieved articles was evaluated according to the RCT or case–control study criteria. The success rate of treatment, intraocular pressure (IOP) and visual acuity were statistically compared. RevMan 5.3 software was used for the meta-analysis. In total, 6 relevant control studies were selected in this study with a total sampling of 429 cases (429 eyes), including 204 eyes in the ECP group and 225 in the non-ECP group. Meta-analysis demonstrated that the clinical efficacy did not significantly differ between 2 groups (P > 0.05). Postoperative IOP was dramatically reduced in both groups. However, it was difficult to evaluate the combined influence of ECP and non-ECP therapies upon IOP reduction. In conclusion, ECP and non-ECP treatment yielded almost equivalent clinical efficacy in treating refractory glaucoma. The IOP-lowering degree, safety, and incidence of complications remain to be further elucidated by RCTs with a larger sample size. PMID:26426659

We report the outcome of seven patients treated for recurrent ovarian cancer with cisplatin after an allergic reaction to carboplatin. One case is presented in which a heavily pretreated patient suffered a severe anaphylactic reaction, which was refractory to standard resuscitative measures and resulted in her death. Six further patients who received cisplatin after documentation of an allergic reaction to carboplatin (CBDCA) for the treatment of recurrent epithelial ovarian cancer between 1993 and 2000 were identified from the MSKCC database. Electronic medical records were reviewed for relevant treatment and outcome data. Five of six of these patients were successfully treated without further allergic reactions. One patient with platinum-refractory disease had an allergic reaction to carboplatin and subsequently to cisplatin. Few patients with a carboplatin allergy are subsequently treated with cisplatin at our center. One patient suffered a serious hypersensitivity reaction following retreatment and died. Based on this limited experience, cross allergy can exist although the true incidence is not known. Routine retreatment of carboplatin-allergic patients with cisplatin in the relapsed setting cannot be recommended without careful consideration of potential risks and benefits.

Surgery is an increasingly important management option for patients with obesity. Laparoscopic adjustable gastric banding is a procedure employed to treat morbid obesity refractory to medical therapy. It works by reducing the capacity of the stomach and promoting early satiety. We report the unusual case of a 33-year-old female who presented acutely 2 years following laparoscopic adjustable gastric banding with cecal volvulus and closed loop obstruction caused by displacement of the connecting tube.

Obsessive compulsive disorder (OCD) is an anxiety disorder characterized by repeated, unwanted thoughts and behaviors. Individuals with this condition often experience significant emotional distress secondary to their symptoms. Additionally, impairments in attention/concentration, processing speed, and executive functions are typically observed. The exact pathology of OCD remains unknown; consequently, it can be difficult to treat patients with severe symptomatology. Deep brain stimulation (DBS) may be a viable treatment option for individuals who do not respond to medication and/or cognitive behavioral therapy. The following case discusses DBS of the anterior limb of the internal capsule for a patient with severe, therapy-refractory OCD, including pre- to postoperative neurocognitive and psychiatric changes.

Abiraterone, a potent CYP 17 inhibitor, is standard treatment in docetaxel refractory, metastatic castrate resistant prostate cancer (mCRPC). However, in countries where abiraterone has not been approved yet, or for patients who cannot afford it, ketoconazole is used as an alternative CYP 17 inhibitor. Although preclinical data suggests that ketoconazole is a less potent inhibitor of CYP 17, there are limited clinical data comparing both agents. We aimed to compare the clinical effectiveness of abiraterone versus ketoconazole in docetaxel refractory mCRPC. Records from mCRPC patients treated with ketoconazole (international multicenter database, n = 162) were reviewed retrospectively. Twenty-six patients treated post docetaxel were individually matched by clinicopathologic factors to patients treated with abiraterone (national multicenter database, n = 140). We compared the PSA response, biochemical and radiological progression free survival (PFS), and overall survival (OS) between the groups. PFS and OS were determined by Cox regression. The groups were matched by Gleason score, pre-treatment disease extent, ECOG PS, pre-treatment risk category (Keizman, Oncologist 2012). Furthermore, they were balanced regarding other known confounding risk factors. In the groups of abiraterone versus ketoconazole, PSA response was 46% versus 19% (OR 4.3, P = 0.04), median biochemical PFS 7 versus 2 months (HR 1.54, P = 0.02), median radiological PFS 8 versus 2.5 months (HR 1.8, P = 0.043), median OS 19 versus 11 months (HR 0.53, P = 0.79), and treatment interruption d/t severe adverse events 8% (n = 2) versus 31% (n = 8) (OR 0.6, P = 0.023). In docetaxel refractory mCRPC, the outcome of abiraterone treatment may be superior to ketoconazole. Copyright © 2016 Elsevier Inc. All rights reserved.

Patients with autoimmune multilineage cytopenias are often refractory to standard therapies requiring chronic immunosuppression with medications with limited efficacy and high toxicity. We present data on 30 patients treated on a multicenter prospective clinical trial using sirolimus as monotherapy. All children (N = 12) with autoimmune lymphoproliferative syndrome (ALPS) achieved a durable complete response (CR), including rapid improvement in autoimmune disease, lymphadenopathy, and splenomegaly within 1 to 3 months of starting sirolimus. Double-negative T cells were no longer detectable in most, yet other lymphocyte populations were spared, suggesting a targeted effect of sirolimus. We also treated 12 patients with multilineage cytopenias secondary to common variable immunodeficiency (CVID), Evans syndrome (ES), or systemic lupus erythematosus (SLE), and most achieved a CR (N = 8), although the time to CR was often slower than was seen in ALPS. Six children with single-lineage autoimmune cytopenias were treated and only 2 responded. Sirolimus was well tolerated with very few side effects. All of the responding patients have remained on therapy for over 1 year (median, 2 years; range, 1 to 4.5 years). In summary, sirolimus led to CR and durable responses in a majority of children with refractory multilineage autoimmune cytopenias. The responses seen in ALPS patients were profound, suggesting that sirolimus should be considered as a first-line, steroid-sparing treatment of patients needing chronic therapy. The results in other multilineage autoimmune cytopenia cohorts were encouraging, and sirolimus should be considered in children with SLE, ES, and CVID. This trial was registered at www.clinicaltrials.gov as #NCT00392951. PMID:26504182

An Approach to Diagnosis and Endovascular Treatment of Refractory Ascites in Liver Transplant: A Pictorial Essay and Clinical Practice Algorithm.

Pereira, Keith; Salsamendi, Jason; Fan, Ji

Recipients of liver transplant are surviving longer as both the surgical procedure and postsurgical care have improved. Despite improvements, serious complications from the procedure remain that significantly affect patient outcome and may result in retransplant. Refractory ascites is one complication, occurring in about 5.6% of transplant recipients. Management of refractory ascites after liver transplant presents a challenge to the multidisciplinary team caring for these patients. We discuss approaches to the diagnosis and treatment of refractory ascites after liver transplant, based on a literature review, with a primary focus on vascular causes. These approaches are illustrated by case examples highlighting our experiences at an academic tertiary medical center. We propose a clinical practice algorithm for optimal endovascular treatment of refractory ascites after liver transplant. The cornerstone of refractory ascites care is diagnosis and treatment of the cause. Vascular causes are not infrequently encountered and, if not treated early, are associated with graft loss and high morbidity and mortality and are major indications for retransplant. For patients with recurrent disease or graft rejection needing large volume paracentesis, the use of a transjugular intrahepatic portosystemic shunt may serve as a bridge to more definitive treatment (retransplant), although it may not be as effective for managing ascites as splenic artery embolization, arguably underused, which is emerging as a potential alternative treatment option. A multidisciplinary strategy for the diagnosis and care of patients with refractory ascites after liver transplant is crucial, with endovascular treatment playing an important role. The aim is for this document to serve as a concise and informative reference to be used by those who may care for patients with this rare yet serious diagnosis.

Amiodarone is associated with thyroid dysfunction and life-threatening thyrotoxicosis. In medically refractory cases, or where medical therapy is contraindicated, thyroidectomy may be required. To decrease perioperative thyroid storm and to reduce overall surgical risk, apheresis may be considered preoperatively to restore euthyroidism. We report a 46-year-old female with a history of cardiac arrhythmia and tachycardia-induced cardiomyopathy for which she received amiodarone. Months after discontinuation of amiodarone, the patient presented with wide complex tachycardia and symptoms of thyrotoxicosis. Laboratory testing confirmed severe thyrotoxicosis which was subsequently refractory to medical therapy. Total thyroidectomy was required. Following a total of 10 apheresis treatments, thyroid hormone levels were reduced to near normal levels and the patient's symptoms improved. Thyroidectomy was performed without intraoperative or postoperative complication. In the setting of life-threatening, medically refractory amiodarone-induced thyrotoxicosis, therapeutic apheresis can effectively reduce thyroid hormone levels and restore a state of clinical and biochemical euthyroidism. © 2013 Wiley Periodicals, Inc.

Cyclosporine is considered a safe and effective treatment of severe steroid-refractory ulcerative colitis (UC). However, few data are available concerning its safety profile in pregnant women. We report here the experience of 5 GETAID centers. In a retrospective study data on patients with severe UC treated with cyclosporine during pregnancy were extracted from medical records of consecutive patients treated between 2001 and 2007. Eight patients (median age 30.5 years old) were identified. At the time of flare-up the median duration of pregnancy was 11.5 weeks of gestation (range 4-25). Seven patients had pancolitis. All patients had more than 3 commonly used clinical and biological severity criteria. Three patients had severe endoscopic lesions and 5 patients had not. All patients received intravenous corticosteroids for at least 7 days before introduction of cyclosporine. Two patients received azathioprine during treatment with cyclosporine. No severe infections or other complications due to treatment were observed. Treatment was effective in 7/8 patients. One patient received infliximab due to cyclosporine therapy failure with a good outcome. No colectomy was performed during pregnancy. Seven pregnancies were conducted to term, but 1 in utero death occurred due to maternal absence of S-protein. Two newborns were premature, including 1 case of hypotrophy. No malformations were observed. In our experience, treatment with cyclosporine for steroid-refractory UC during pregnancy can be considered safe and effective.

Laparoscopic sleeve gastrectomy (LSG) has gained significant popularity in the USA, and consequently resulted in patients experiencing new-onset gastroesophageal reflux disease (GERD) following this bariatric procedure. Patients with GERD refractory to medical therapy present a more challenging situation limiting the surgical options to further treat the de novo GERD symptoms since the gastric fundus to perform a fundoplication is no longer an option. The aim of this study is to determine if the LINX® magnetic sphincter augmentation system is a safe and effective option for patients with new gastroesophageal reflux disease following laparoscopic sleeve gastrectomy. This study was conducted at the University Medical Center. This is a retrospective review of seven consecutive patients who had a laparoscopic LINX® magnetic sphincter device placement for patients with refractory gastroesophageal reflux disease after laparoscopic sleeve gastrectomy between July 2014 and April 2015. All patients were noted to have self-reported greatly improved gastroesophageal reflux symptoms 2-4 weeks after their procedure. They were all noted to have statistically significant improved severity and frequency of their reflux, regurgitation, epigastric pain, sensation of fullness, dysphagia, and cough symptoms in their postoperative GERD symptoms compared with their preoperative evaluation. This is the first reported pilot case series, illustrating that the LINX® device is a safe and effective option in patients with de novo refractory gastroesophageal reflux disease after a laparoscopic sleeve gastrectomy despite appropriate weight loss.

Vulvovaginitis (VV) is one of the most commonly encountered problems by a gynecologist. Many women frequently self-treat with over-the-counter medications, and may present to their health-care provider after a treatment failure. Vulvovaginal candidiasis, bacterial vaginosis, and trichomoniasis may occur as discreet or recurrent episodes, and have been associated with significant treatment cost and morbidity. We present an update on diagnostic capabilities and treatment modalities that address recurrent and refractory episodes of VV. Copyright © 2014 Elsevier Ltd. All rights reserved.

Ranolazine is a novel antianginal medication approved for the treatment of chronic angina. There are only limited data concerning the efficacy of ranolazine in reducing healthcare resource utilization in patients with refractory angina pectoris. The primary objective of this analysis was to evaluate the efficacy and safety of ranolazine in refractory angina pectoris. In addition, the impact of ranolazine on healthcare resource utilization was assessed. Consecutive patients with refractory angina pectoris treated with ranolazine at two cardiology practices in the state of Nebraska were included in this analysis. The Canadian Cardiovascular Society (CCS) angina class and frequency and type of healthcare resource consumption were determined during the 12 months prior to and the 12 months after initiation of ranolazine. A total of 150 pts (64 % men) with a mean age of 66 ± 12 years were included in this analysis. All patients had previously undergone coronary revascularization. Nitrates, β-adrenoceptor antagonists (β-blockers), and calcium antagonists (calcium channel blockers) were being used in 83, 97, and 75 % of patients, respectively. During ranolazine treatment, a significant improvement in CCS angina class was observed, with 23 patients improving by one class and no patient experiencing a deterioration in functional class (p = 0.025). A total of 53 side effects occurred in 28 (19 %) patients receiving ranolazine. Of those patients with side effects, four required dose reduction and seven required drug discontinuation. The frequency of clinic visits and emergency room visits was lower during ranolazine treatment, but the differences in frequency were not significant. The number of patients hospitalized and the number of hospitalizations were significantly lower during ranolazine therapy than in the pre-ranolazine study period (p = 0.002). Ranolazine improved the CCS angina class and reduced hospitalizations over a 12-month follow-up period in a group of patients with difficult-to-treat refractory angina pectoris.

Treating inflammatory bowel disease by adsorptive leucocytapheresis: a desire to treat without drugs.

Ulcerative colitis and Crohn's disease are the major phenotypes of the idiopathic inflammatory bowel disease (IBD), which afflicts millions of individuals throughout the world with debilitating symptoms, impairing function and quality of life. Current medications are aimed at reducing the symptoms or suppressing exacerbations. However, patients require life-long medications, and this can lead to drug dependency, loss of response together with adverse side effects. Indeed, drug side effects become additional morbidity factor in many patients on long-term medications. Nonetheless, the efficacy of anti-tumour necrosis factors (TNF)-α biologics has validated the role of inflammatory cytokines notably TNF-α in the exacerbation of IBD. However, inflammatory cytokines are released by patients' own cellular elements including myeloid lineage leucocytes, which in patients with IBD are elevated with activation behaviour and prolonged survival. Accordingly, these leucocytes appear logical targets of therapy and can be depleted by adsorptive granulocyte/monocyte apheresis (GMA) with an Adacolumn. Based on this background, recently GMA has been applied to treat patients with IBD in Japan and in the European Union countries. Efficacy rates have been impressive as well as disappointing. In fact the clinical response to GMA seems to define the patients' disease course, response to medications, duration of active disease, and severity at entry. The best responders have been first episode cases (up to 100%) followed by steroid naïve and patients with a short duration of active disease prior to GMA. Patients with deep ulcers together with extensive loss of the mucosal tissue and cases with a long duration of IBD refractory to existing medications are not likely to benefit from GMA. It is clinically interesting that patients who respond to GMA have a good long-term disease course by avoiding drugs including corticosteroids in the early stage of their IBD. Additionally, GMA is very much favoured by patients for its good safety profile. GMA in 21st century reminds us of phlebotomy as a major medical practice at the time of Hippocrates. However, in patients with IBD, there is a scope for removing from the body the sources of pro-inflammatory cytokines and achieve disease remission. The bottom line is that by introducing GMA at an early stage following the onset of IBD or before patients develop extensive mucosal damage and become refractory to medications, many patients should respond to GMA and avoid pharmacologics. This should fulfill the desire to treat without drugs.

A ketogenic diet has been used successfully to treat intractable epilepsy. However, the role of early intravenous initiation of ketogenic diet in the acute phase of super-refractory status epilepticus is not well-described. An intravenous ketogenic diet was administered to a boy with super-refractory status epilepticus. At 24 hours after intravenous ketogenic diet, moderate ketosis appeared, and thiamylal was successfully weaned at 70 hours after admission. An intravenous ketogenic regimen led to subsequent ketosis and seizure control in a child with super-refractory status epilepticus. Early induction of ketosis may be a novel strategy to effectively treat super-refractory status epilepticus. Although there are few data regarding the early use of intravenous ketogenic diet in the treatment of super-refractory status epilepticus, it may be considered an alternative option.

The Neuromodulation Appropriateness Consensus Committee (NACC) of the International Neuromodulation Society (INS) evaluated evidence regarding the safety and efficacy of neurostimulation to treat chronic pain, chronic critical limb ischemia, and refractory angina and recommended appropriate clinical applications. The NACC used literature reviews, expert opinion, clinical experience, and individual research. Authors consulted the Practice Parameters for the Use of Spinal Cord Stimulation in the Treatment of Neuropathic Pain (2006), systematic reviews (1984 to 2013), and prospective and randomized controlled trials (2005 to 2013) identified through PubMed, EMBASE, and Google Scholar. Neurostimulation is relatively safe because of its minimally invasive and reversible characteristics. Comparison with medical management is difficult, as patients considered for neurostimulation have failed conservative management. Unlike alternative therapies, neurostimulation is not associated with medication-related side effects and has enduring effect. Device-related complications are not uncommon; however, the incidence is becoming less frequent as technology progresses and surgical skills improve. Randomized controlled studies support the efficacy of spinal cord stimulation in treating failed back surgery syndrome and complex regional pain syndrome. Similar studies of neurostimulation for peripheral neuropathic pain, postamputation pain, postherpetic neuralgia, and other causes of nerve injury are needed. International guidelines recommend spinal cord stimulation to treat refractory angina; other indications, such as congestive heart failure, are being investigated.

Systemic amyloidosis is a disease that often involves multiple organ systems, including the peripheral nervous system. Patients may present with severe, refractory neuropathic pain; however, the optimal treatment approach for pain for these patients remains unclear. A man with severe, refractory neuropathic pain in his bilateral upper and lower extremities and the trunk secondary to amyloid neuropathy is presented. Multiple medication trials, including neuropathic and opioid agents, produced considerable adverse effects and minimal relief. Scrambler therapy, a novel electrical stimulation modality, was used and was associated with substantial short-term but nonsustained benefit. Spinal cord stimulation was considered, but given his diffuse symptoms, it was deemed a less-than-optimal approach. Ultimately, an intrathecal drug delivery system was placed with infusion of hydromorphone, resulting in substantial pain reduction in all involved areas and with an improved adverse effect profile. This intervention resulted in immense improvement in the patient's quality of life, despite progression of his systemic amyloidosis. Severe pain in the setting of amyloid neuropathy is often difficult to treat. To our knowledge, this represents the first report of Scrambler therapy or an implanted intrathecal drug delivery system used for a patient with refractory amyloidosis-related neuropathic pain, resulting in substantial analgesic benefit and improved quality of life.

Patients who were surgically treated for Cushing's syndrome postoperatively surrender to "primary" adrenal insufficiency. However, the preoperative over-secretion of cortisol or the postoperative administration of excessive glucocorticoids can cause "secondary" adrenal insufficiency, in which the prevalence of hyponatremia is usually lower than that of primary adrenal insufficiency. A 60-year-old woman with a past medical history of Cushing's syndrome developed hyponatremia with symptoms of acute glucocorticoid deficiency, such as prolonged general fatigue and anorexia, after upper respiratory tract infection. A decrease in the serum cortisol level and the lack of increase in the ACTH level, despite the increased demand for cortisol, enabled a diagnosis of "secondary" adrenal insufficiency. Although the initial fluid replacement therapy was not effective, co-administration of dexamethasone and sodium chloride quickly resolved her symptoms and ameliorated the refractory hyponatremia. In this case, the hypothalamic-pituitary axis of the patient was thought to have become suppressed long after the surgical treatment for Cushing's syndrome. This case suggested a mechanism of refractory hyponatremia caused by secondary adrenal insufficiency, for which the administration of dexamethasone and sodium chloride exerted additional therapeutic efficacy.

Autologous hematopoietic stem cells are gaining ground as an effective and safe treatment for treating severe refractory Crohn's disease (CD). Autologous hematopoietic stem cell therapy (AHSCT) induces resetting of the immune system by de novo regeneration of T-cell repertoire and repopulation of epithelial cells by bone-marrow derived cells to help patients achieve clinical and endoscopic remission. Areas covered: Herein, the authors discuss the use of AHSCT in treating patients with CD. Improvements in disease activity have been seen in patients with severe autoimmune disease and patients with severe CD who underwent AHSCT for a concomitant malignant hematological disease. Clinical and endoscopic remission has been achieved in patients treated with AHSCT for CD. The only randomized trial published to date, the ASTIC Trial, did not support further use of AHSCT to treat CD. Yet, critics of this trial have deemed AHSCT as a promising treatment for severe refractory CD. Expert opinion: Even with the promising evidence presented for HSCT for refractory CD, protocols need to be refined through the collaboration of GI and hemato-oncology professionals. The goal is to incorporate safe AHSCT and restore tolerance by delivering an effective immune 'cease fire' as a treatment option for severe refractory CD.

Clinical trials have confirmed the efficacy of focused ultrasound (FUS) thalamotomy in essential tremor, but its effectiveness and safety for managing tremor-dominant Parkinson disease (TDPD) is unknown. To assess safety and efficacy at 12-month follow-up, accounting for placebo response, of unilateral FUS thalamotomy for patients with TDPD. Of the 326 patients identified from an in-house database, 53 patients consented to be screened. Twenty-six were ineligible, and 27 were randomized (2:1) to FUS thalamotomy or a sham procedure at 2 centers from October18, 2012, to January 8, 2015. The most common reasons for disqualification were withdrawal (8 persons [31%]), and not being medication refractory (8 persons [31%]). Data were analyzed using intention-to-treat analysis, and assessments were double-blinded through the primary outcome. Twenty patients were randomized to unilateral FUS thalamotomy, and 7 to sham procedure. The sham group was offered open-label treatment after unblinding. The predefined primary outcomes were safety and difference in improvement between groups at 3 months in the on-medication treated hand tremor subscore from the Clinical Rating Scale for Tremor (CRST). Secondary outcomes included descriptive results of Unified Parkinson's Disease Rating Scale (UPDRS) scores and quality of life measures. Of the 27 patients, 26 (96%) were male and the median age was 67.8 years (interquartile range [IQR], 62.1-73.8 years). On-medication median tremor scores improved 62% (IQR, 22%-79%) from a baseline of 17 points (IQR, 10.5-27.5) following FUS thalamotomy and 22% (IQR, -11% to 29%) from a baseline of 23 points (IQR, 14.0-27.0) after sham procedures; the between-group difference was significant (Wilcoxon P = .04). On-medication median UPDRS motor scores improved 8 points (IQR, 0.5-11.0) from a baseline of 23 points (IQR, 15.5-34.0) following FUS thalamotomy and 1 point (IQR, -5.0 to 9.0) from a baseline of 25 points (IQR, 15.0-33.0) after sham procedures. Early in the study, heating of the internal capsule resulted in 2 cases (8%) of mild hemiparesis, which improved and prompted monitoring of an additional axis during magnetic resonance thermometry. Other persistent adverse events were orofacial paresthesia (4 events [20%]), finger paresthesia (1 event [5%]), and ataxia (1 event [5%]). Focused ultrasound thalamotomy for patients with TDPD demonstrated improvements in medication-refractory tremor by CRST assessments, even in the setting of a placebo response.

Deep brain stimulation (DBS) has been reported to have beneficial effects in severe, treatment-refractory cases of obsessive-compulsive disorder (OCD) and Tourette syndrome (TS). In this report, the authors present the first case in which DBS was used to treat the neuropsychiatric symptoms of Kleefstra syndrome, a rare genetic disorder characterized by childhood hypotonia, intellectual disability, distinctive facial features, and myriad psychiatric and behavioral disturbances. A 24-year-old female patient with childhood hypotonia, developmental delay, and diagnoses of autism spectrum disorder, OCD, and TS refractory to medical management underwent the placement of bilateral ventral capsule/ventral striatum (VC/VS) DBS leads, with clinical improvement. Medical providers and family observed gradual and progressive improvement in the patient's compulsive behaviors, coprolalia, speech, and social interaction. Symptoms recurred when both DBS electrodes failed because of lead fracture and dislodgement, although the clinical benefits were restored by lead replacement. The symptomatic and functional improvements observed in this case of VC/VS DBS for Kleefstra syndrome suggest a novel indication for DBS worthy of further investigation.

Infliximab has been proven to be effective for refractory luminal and fistulizing Crohns disease (CD). We performed this study to demonstrate the efficacy of infliximab in Korean CD patients. Medical records of 40 CD patients who had been treated with infliximab were reviewed retrospectively. Among 40 patients, 11 (27.5%) patients were treated for refractory luminal disease, 14 (35%) for fistulizing disease, and 15 (37.5%) for both types. Clinical response rate was higher in 26 patients with refractory luminal disease (Complete response (CR), 73.1%; Partial response (PR), 23.1%) than in 29 patients with fistulizing disease (CR, 41.4%; PR, 31%) (p=0.024). The clinical response rate tended to be higher in 28 patients with external fistulas (CR, 46.4%; PR, 32.2%) than 4 patients with internal fistulas (PR, 25%; NR, 75%) (p=0.064). Among patients with external fistulas, the response rate of 8 patients with enterocutaneous fistulas (CR, 50%; PR, 12.5%) was not different from 20 patients with perianal fistulas (CR, 45%; PR, 40%). Among 20 patients with perianal fistulas, the response rate of 6 patients with perianal fistulas without a history of operation (CR, 83.3%; PR, 0%) was higher than 14 patients with perianal fistulas resistant to previous surgical treatment (CR, 28.6%; PR, 57.1%) (p=0.044). As for adverse reaction, 7 patients experienced mild infusion reaction, and 2 patients developed serious infection. Infliximab is more effective for refractory luminal disease than for fistulizing disease. In addition, clinical responses to infliximab are different according to subtypes of fistulas. These findings should be considered for the proper use of infliximab.

Patients with myelodysplastic syndrome (MDS) or severe anemia requiring repeated red blood cell (RBC) transfusions risk developing transfusional iron overload, which can reduce survival. Iron chelation therapy (ICT) has been shown to improve survival and quality of life in patients; however, ICT utilization in clinical practices is not well understood. Medical records of patients diagnosed with MDS or severe anemia at least 6 months before data extraction, aged at least 21 years at diagnosis, and who received at least one RBC transfusion were reviewed. ICT eligibility was defined as at least 20 units of RBCs transfused or at least two serum ferritin levels exceeding 1000 microg/L. Study endpoint was ICT treatment rate among ICT-eligible patients with lower-risk MDS (International Prognostic Scoring System [low or intermediate-1]; World Health Organization [refractory anemia {RA}, refractory anemia with ringed sideroblasts {RARS}, refractory cytopenia with multilineage dysplasia {RCMD}, refractory cytopenia with multilineage dysplasia and ringed sideroblasts, or 5q]; French-American-British [RA/RARS]). Among 78 ICT-eligible patients with lower-risk MDS, 32 (41%) received ICT. At ICT initiation, treated patients received on average 13.3 transfusions (27.6 units) and mean first post-ICT initiation serum ferritin was twice the MDS Foundation recommendation at 1949 microg/L. Median overall survival for all ICT-eligible patients was significantly longer for those ICT-treated patients than untreated patients (8.7 years vs. 4.7 years, log-rank p = 0.02; multivariate hazard ratio 0.372, p = 0.03). This study finds only 41% of ICT-eligible patients with lower-risk MDS received ICT in clinical practice, and treatment was initiated later than recommended. Receipt of ICT was associated with significantly longer survival.

Heidenreich, Dorothee C; Giordano, Paola; Kirby, Barbara M

2016-11-01

To report a case of refractory seizures following congenital portosystemic shunt (CPSS) ligation that regained normal neurologic and hepatic function with novel treatment. Medical care included constant rate infusions (CRI) of propofol and medetomidine in conjunction with phenobarbital and supportive intensive care. A 2-year-old neutered male Bichon Frise was diagnosed with a single extrahepatic CPSS based on typical clinical signs, laboratory data, abdominal ultrasound, and computed tomographic angiography. Following initiation of standard medical treatment, a complete surgical ligation of the CPSS was performed. Recovery was uneventful until postligation neurologic dysfunction developed 54 hours after surgery. Seizures were controlled with phenobarbital (6 mg/kg IM q 12 h) and propofol CRI (0.3-0.6 mg/kg/min). Attempts to wean the dog from the propofol CRI resulted in recurrence of seizure activity until the addition of medetomidine CRI (0.016 μg/kg/min) 76 hours after initiation of drug-induced coma allowed gradual discontinuation of the propofol CRI. The dog regained full neurologic and hepatic function and had no further seizure activity apart from a small number of seizure episodes 5 and 22 months later. Adjustments in antiepileptic treatment resulted in no further neurologic dysfunction at 27-month follow-up. This report highlights the potential benefit of medetomidine CRI for treatment of postattenuation refractory seizures, which to date have proven impossible to predict and difficult to treat with high mortality rates and persistent neurological deficits in surviving animals. Neuroprotective, drug-sparing, and anti-hypertensive features of medetomidine might improve outcome in postligation refractory seizures. Further investigation and clinical application of medetomidine CRI may improve outcome in this complication of CPSS attenuation. © Veterinary Emergency and Critical Care Society 2015.

Standard therapeutic options for patients with relapsed or refractory peripheral T cell lymphoma-not otherwise specified (PTCL-NOS) remain unclear. There are few large cohort studies specifically focused on gemcitabine-based chemotherapy for PTCL-NOS. We retrospectively reviewed patients with relapsed or refractory PTCL-NOS who received salvage GDP (gemcitabine, dexamethasone, and cisplatin) chemotherapy at the Cancer Hospital, Chinese Academy of Medical Sciences (CAMS) and Peking Union Medical College (PUMC), Beijing, China, from May 2008 to August 2014. Twenty-five patients were enrolled and analyzed. The median number of cycles of GDP chemotherapy per patient was four (range, 2-8 cycles). Overall response rate was 64.0% (16/25) with five achieved complete remission or complete remission unconfirmed. After a median follow-up of 9 months, median overall survival (OS) and progression-free survival after relapse or progression (second-PFS) were 9.3 and 5.4 months. One-year PFS rate and 1-year OS rate were 27.4% and 43.9%, respectively. Median second-PFS was significantly longer in patients sensitive to GDP than the ones resistant to the treatment (10.3 vs. 2.8 months, p < .01). In addition, the low International Prognostic Index, low Prognostic Index for T cell lymphoma, or normal level of LDH in serum was associated with favorable prognosis. Grade 3/4 adverse effect was observed in 10 of 25 patients treated with GDP including neutropenia (8/25), thrombocytopenia (5/25), and anemia (4/25). Taken together, our study suggests that GDP is an effective and optional salvage regimen for relapsed or refractory PTCL-NOS.

Medical therapy of gastroesophageal reflux disease (GERD) is based on the use of proton pump inhibitors (PPIs) as first choice treatment. Despite their effectiveness, about 20-30% of patients report an inadequate response and alternative drugs are required. Areas covered: This review provides an overview of current pharmacotherapy for treating GERD by showing the results of PPIs, reflux inhibitors, antidepressants and mucosa protective medications. Expert opinion: Medical therapy of GERD does not definitely cure the disease, because even PPIs are not able to change the key factors responsible for it. However, they remain the mainstay of medical treatment, allowing us to alleviate symptoms, heal esophagitis and prevent complications in the majority of cases. Nevertheless, many patients do not respond, because acid does not play any pathogenetic role. Prokinetics and reflux inhibitors have the potential to control motor abnormalities, but the results of clinical trials are inconsistent. Antidepressant drugs are effective in specific subgroups of NERD patients with visceral hypersensitivity, but larger, controlled clinical studies are necessary. Protective drugs or medical devices have been recently adopted to reinforce mucosal resistance and preliminary trials have confirmed their efficacy either combined with or as add-on medication to PPIs in refractory patients.

In addition to conventional management of limiting absorption, increasing elimination and hemodynamic support intravenous (IV) calcium infusion, hyperinsulinemia-euglycemia therapy, glucagon infusion, and IV lipid emulsion have been tried. Extracorporeal circulatory assist device support has been reported as a rescue therapy in overdose refractory to maximal medical therapy. We report three patients with cardiovascular medication overdose presenting with profound cardiovascular instability refractory to medical therapy. Venoarterial extracorporeal membrane oxygenation support (VA ECMO) was initiated to provide hemodynamic support. Despite the occurrence of device-associated complications, the outcome was good and all patients survived. VA ECMO may be considered in patients with severe refractory shock due to cardiotoxic medication overdose. PMID:29531453

2013-09-01

None of the medications used in clinical practice to treat sarcoidosis have been approved by the regulatory authorities. Understanding how to use disease-modifying antisarcoid drugs, however, is essential for physicians treating patients with sarcoidosis. This review summarizes the recent studies of medications used for sarcoidosis with a focus on nonsteroidal therapies. Studies from 2006 to 2013 were considered for review to update clinicians on the most relevant literature published over the last few years. Several recently published pieces of evidence have helped expand our ability to more appropriately sequence second-line and third-line therapies for sarcoidosis. For instance, methotrexate and azathioprine may be useful and well tolerated medications as second-line treatment. Mycophenolate mofetil might have a role in neurosarcoidosis. TNF-α blockers and other biologics seem to be well tolerated medications for the most severely affected patients. Corticosteroids remain the first-line therapy for sarcoidosis as many patients never require treatment or only necessitate a short treatment duration. Second-line and third-line therapies described in this article should be used in patients with progressive or refractory disease or when life-threatening complications are evident at the time of presentation.

Baseline blood tests revealed no abnormality; however, subsequent investigations showed a raised plasma homocysteine (HC) level. The patient has been treated for refractory epilepsy for a number of years. Although antiepileptic medications have been shown to reduce folate levels and result in a raised HC level, this has not previously been shown to be to a level causing a retinal vascular event.

The objective of this work is to report our experience with (131)I therapy without recent antithyroid drug (ATD) pretreatment for refractory severe hyperthyroidism complicated by hyperbilirubinemia due to hepatic dysfunction. Five patients with refractory severe hyperthyroidism were treated with (131)I at 90 to 120 μCi/g-thyroid (total activity, 6.2 to 10.1 mCi). The patients previously had received ATD treatment from 2 months to 12 years and discontinued ATDs from 2 months to 4 years before (131)I treatment due to treatment failure or severe jaundice. Prior to (131)I therapy, the patients were asked to take a low-iodine diet and were treated with bisoprolol fumarate, digoxin, furosemide, S-adenosylmethionine, polyene phosphatidylcholine, and plasma exchange as supportive treatment for related clinical conditions. Four of the patients also received lithium carbonate in conjunction with their (131)I treatment. The patients were followed for 4 to 9 years after (131)I therapy. After (131)I treatment, jaundice disappeared completely within 3 to 4 months in all patients, and liver function tests returned to normal. Concurrent atrial fibrillation and heart failure, leukopenia and thrombocytopenia, or thrombocytopenia and left cardiac enlargement improved remarkably in 3 patients during the follow-up period. Three to 45 months after (131)I treatment, hypothyroidism was noted in the patients and they were treated with L-thyroxine replacement therapy. (131)I therapy without recent ATD pretreatment for refractory severe hyperthyroidism complicated by serious jaundice appears to be safe and effective, with good long-term results. It may be the preferred therapy for such patients and should be used as early as possible.

Intravenous immunoglobulin (IVIG) has been shown to be effective in treating steroid-refractory dermatomyositis (DM). There remains no evidence of its cost-effectiveness in Thailand. Our objective was to estimate the cost utility of IVIG as a second-line therapy in steroid-refractory DM in Thailand. A Markov model was developed to estimate the relevant costs and health benefits for IVIG plus corticosteroids in comparison with immunosuppressant plus corticosteroids in steroid-refractory DM from a societal perspective over a patient's lifetime. The effectiveness and utility parameters were obtained from clinical literature, meta-analyses, medical record reviews, and patient interviews, whereas cost data were obtained from an electronic hospital database and patient interviews. Costs are presented in $US, year 2012 values. All future costs and outcomes were discounted at a rate of 3% per annum. One-way and probabilistic sensitivity analyses were also performed. Over a lifetime horizon, the model estimated treatment under IVIG plus corticosteroids to be cost saving compared with immunosuppressant plus corticosteroids, where the saving of costs and incremental quality-adjusted life-years (QALYs) were $US4738.92 and 1.96 QALYs, respectively. Sensitivity analyses revealed that probability of response of immunosuppressant plus corticosteroids was the most influential parameter on incremental QALYs and costs. At a societal willingness-to-pay threshold in Thailand of $US5148 per QALY gained, the probability of IVIG being cost effective was 97.6%. The use of IVIG plus corticosteroids is cost saving compared with treatment with immunosuppressant plus corticosteroids in Thai patients with steroid-refractory DM. Policy makers should consider using our findings in their decision-making process for adding IVIG to corticosteroids as the second-line therapy for steroid-refractory DM patients.

Tertiary care surgical intensive care unit. In the first case, a 54-year-old male with history of alcoholic cirrhosis developed new-onset seizures refractory to phenytoin and levetiracetam 8 days after liver transplantation. In the second case, a 59-year-old male with hepatitis C infection developed intracranial hemorrhage and new-onset seizures refractory to phenytoin, levetiracetam, and pentobarbital. The third patient is a 78-year-old male with a history of alcohol dependence who was admitted for an intraventricular bleed and developed new onset of refractory seizures. Intravenous pyridoxine followed by oral pyridoxine. In all 3 cases, seizures persisted despite escalation of conventional antiepileptic medications but resolved within 2 days of pyridoxine supplementation. In each case, low serum pyridoxal 5'-phosphate concentrations normalized with pyroxidine administration. Although refractory seizures caused by vitamin B(6) deficiency are rare in adults, it should be considered in critically ill adult patients with refractory seizures.

Refractory Depression, Fatigue, Irritable Bowel Syndrome, and Chronic Pain: A Functional Medicine Case Report.

Single-disorder or single-organ-system clinical practice guidelines are often of limited usefulness in guiding effective management of patients with chronic multidimensional signs and symptoms. The presence of multiple long-standing medical problems in a given patient despite intensive medical effort suggests that addressing systemic core imbalances could complement more narrowly focused approaches. A 72-year-old man experiencing longstanding depression, fatigue, irritable bowel syndrome, and chronic pain in the context of additional refractory illnesses was assessed and treated, guided by a system-oriented approach to underlying core imbalances termed functional medicine. This patient was referred from a team of clinicians representing primary care, cardiology, gastroenterology, hematology, and psychology. Prior treatment had been unsuccessful in managing multiple chronic comorbidities. Diagnostic assessment included comprehensive stool and nutritional/metabolic laboratory testing. The blood-, urine-, or stool-based measurements of relevant markers for multiple systemic issues, including digestion/absorption, inflammation, oxidative stress, and methylation, identified previously unrecognized root causes of his constellation of symptoms. These functional measurements guided rational recommendations for dietary choices and supplementation. The patient experienced steady and significant improvement in his mental health, fatigue, chronic pain, and irritable bowel syndrome-as well as the unexpected resolution of his chronic idiopathic pancytopenia. The success in this case suggests that other patients with chronic, complex, and treatment-refractory illness may benefit from a system-oriented assessment of core imbalances guided by specialized nutritional/metabolic and digestive laboratory testing.

Refractory epilepsy often has deleterious effects on an individual's health and quality of life. Early identification of patients whose seizures are refractory to antiepileptic drugs is important in considering the use of alternative treatments. Although idiopathic epilepsy is regarded as having a significantly lower risk factor of developing refractory epilepsy, still a subset of patients with idiopathic epilepsy might be refractory to medical treatment. In this study, we developed an effective method to predict the refractoriness of idiopathic epilepsy. Sixteen EEG segments from 12 well-controlled patients and 14 EEG segments from 11 refractory patients were analyzed at the time of first EEG recordings before antiepileptic drug treatment. Ten crucial EEG feature descriptors were selected for classification. Three of 10 were related to decorrelation time, and four of 10 were related to relative power of delta/gamma. There were significantly higher values in these seven feature descriptors in the well-controlled group as compared to the refractory group. On the contrary, the remaining three feature descriptors related to spectral edge frequency, kurtosis, and energy of wavelet coefficients demonstrated significantly lower values in the well-controlled group as compared to the refractory group. The analyses yielded a weighted precision rate of 94.2%, and a 93.3% recall rate. Therefore, the developed method is a useful tool in identifying the possibility of developing refractory epilepsy in patients with idiopathic epilepsy.

Clozapine remains the only medication indicated for refractory schizophrenia. As new antipsychotic drugs become available, their efficacy compared to clozapine, particularly in moderately ill patients, is of great clinical interest. We compared risperidone, the first of these, to clozapine in partially responsive patients. Further, since participation of patients usually excluded from clinical trials is increasingly important, we broadened inclusion to a wider patient population. We compared clozapine (n = 53) to risperidone (n = 54) in a randomized, double-blind, 29-week trial in schizophrenia patients (diagnosed using DSM-IV) at 3 research outpatient clinics. Randomization was stratified by "narrow" or "broad" inclusion criteria. The study was conducted between December 1995 and October 1999. Time to treatment discontinuation for lack of efficacy and time to 20% improvement in the Brief Psychiatric Rating Scale psychotic symptom cluster were the primary outcome measures. There were no differences in all-cause discontinuation; clozapine-treated participants were significantly less likely to discontinue for lack of efficacy (15%) than risperidone-treated participants (38%) (Wilcoxon χ(2)1 = 6.10, P = .01). Clozapine resulted in significantly more global improvement (F2,839 = 6.07, P < .01) and asociality improvement (F2,315 = 6.64, P < .01) than risperidone. There was no difference in proportions meeting an a priori criterion of psychosis improvement (risperidone: 57%; clozapine: 71%). Significant adverse effect differences in salivation (F1 = 4.05, P < .05) (F1 = 12.13, P < .001), sweating (F1 = 5.07, P < .05), and tachycardia (F1 = 6.51, P < .05) favored risperidone. Clozapine-treated partially responsive patients were less likely to discontinue treatment for lack of efficacy and improved more globally than those treated with risperidone, although psychotic symptoms did not differ. These findings suggest that clozapine should not be restricted to the most severely ill, treatment-refractory patients; it should be considered as an alternative for patients who have some response to other antipsychotics, but still experience troubling symptoms. © Copyright 2016 Physicians Postgraduate Press, Inc.

[The role of neurologists in deep brain stimulation for Parkinson disease: a neurosurgical perspective].

PubMed

Umemura, Atsushi

2012-01-01

Deep brain stimulation (DBS) has been accepted as an effective treatment for medically refractory Parkinson disease (PD). Appropriate patient selection, safe and precise surgery, and proper postoperative adjustment of stimulation and medication, are essential for the success of DBS. Patient selection is the most important role for the neurologist in DBS treatment. Neurologists treating PD should understand the correct indications and contraindications for DBS, and introduce it in a timely manner to patients who can be expected to benefit substantially from it. For long term treatment of PD, ideally the neurologist in charge of the patient should adjust both the stimulation parameters and medication. Neurologists engaged in this treatment should also have a comprehensive understanding of the probable complications and how to avoid them.

Intravenous immunoglobulin use in managing severe, perioperative peristomal pyoderma gangrenosum following subtotal colectomy with end ileostomy for medically refractory chronic ulcerative colitis

Peristomal pyoderma gangrenosum (PPG) is a rare subtype of pyoderma gangrenosum that is characterized by painful, necrotic ulcerations occurring in the area surrounding an abdominal stoma. PPG is typically seen in younger patients with active inflammatory bowel disease. The etiology and pathogenesis is largely unknown and risk factors are not well defined. Therapy typically involves a combination of aggressive local wound care and systemic medications. Diagnosis and management of PPG can be difficult and data on treatment are limited. We present a case of severe postoperative peristomal recalcitrant to conventional therapy successfully treated with intravenous immune globulin. PMID:25802252

Medication algorithms for the treatment of depression are designed to optimize both treatment implementation and the appropriateness of treatment strategies. Thus, they are essential tools for treating and avoiding refractory depression. Treatment algorithms are explicit treatment protocols that provide specific therapeutic pathways and decision-making tools at critical decision points throughout the treatment process. The present article provides an overview of major projects of algorithm research in the field of antidepressant therapy. The Berlin Algorithm Project and the Texas Medication Algorithm Project (TMAP) compare algorithm-guided treatments with treatment as usual. The Sequenced Treatment Alternatives to Relieve Depression Project (STAR*D) compares different treatment strategies in treatment-resistant patients.

To assess the efficacy of treatment with transcutaneous posterior tibial nerve stimulation (TPTNS) in patients with urge urinary incontinence, of neurogenic or nonneurogenic origin, refractory to first-line therapeutic options. We included 65 patients with urge urinary incontinence refractory to medical treatment. A case history review, a urodynamic study and a somatosensory evoked potentials (SEP) study were conducted before the TPTNS, studying the functional urological condition by means of a voiding diary. The treatment consisted of 10 weekly sessions of TPTNS lasting 30minutes. Some 57.7% of the patients showed abnormal tibial SEPs, and 42% showed abnormal pudendal SEPs. A statistically significant symptomatic improvement was observed in all clinical parameters after treatment with TPTNS, and 66% of the patients showed an overall improvement, regardless of sex, the presence of underlying neurological disorders, detrusor hyperactivity in the urodynamic study or SEP disorders. There were no adverse effects during the treatment. TPTNS is an effective and well tolerated treatment in patients with urge incontinence refractory to first-line therapies and should be offered early in the treatment strategy. New studies are needed to identify the optimal parameters of stimulation, the most effective treatment protocols and long-term efficacy, as well as its applicability to patients with a neurogenic substrate.

CSF Lumbar Drainage: A Safe Surgical Option in Refractory Intracranial Hypertension Associated with Acute Posttraumatic External Hydrocephalus.

PubMed

Manet, R; Schmidt, E A; Vassal, F; Charier, D; Gergelé, L

2016-01-01

External lumbar drainage (ELD) of cerebrospinal fluid (CSF) in posttraumatic refractory intracranial hypertension (ICHT) is controversial. We report our experience of ELD in ICHT associated with acute disturbance of CSF flow within subarachnoid spaces (SASs). Four adult patients admitted to the neurointensive care unit for severe TBI who presented with secondary ICHT are retrospectively reported. When refractory to second-tier therapy, if external ventricular drainage were not possible or failed, and in the absence of an indication for craniotomy to treat a mass lesion or decompressive craniectomy, we assessed the evolution of CSF volume within cranial SAS and checked the presence of basal cisterns and the absence of tonsillar herniation to evaluate interest in and the safety of ELD. As second-tier therapy failed to lower intracranial pressure (ICP; mean ICP 37 ± 5 mmHg), and computed tomography (CT) showed abnormally enlarged cranial SAS following traumatic subarachnoid hemorrhage, patients received ELD. ICP decreased, with immediate and long-term effect (mean ICP 5 mmHg ± 2 mmHg). There were no complications to report. Acute traumatic external hydrocephalus may explain some of the specific situations of secondary increased ICP, with a "normal" CT scan, that is refractory to medical treatment. In these situations, lumbar drainage should be considered to be a safe, minimally invasive, and effective surgical option.

Purpose: To report the first case of gold shunt surgery for treatment of silicone oil–induced refractory glaucoma in a tertiary care academic center, with 5-year follow-up. Design: The study design is a case report. Participants: The participant was a patient who underwent gold shunt surgery. Methods: Institutional Research Ethics Board approval for the study was obtained. A diabetic patient was referred for refractory glaucoma with a history of proliferative diabetic retinal detachment, and surgery with silicone oil. She was uncontrolled on maximal medical therapy and following informed consent, gold shunt surgery was performed. Ocular outcomes and number of medications were reviewed over a 5-year period. Results: Following uncomplicated surgery, intraocular pressure was reduced from 41 to 14 mm Hg, and the number of medications was reduced from 4 to 1. Glaucomatous optic neuropathy remained stable. Conclusions: Gold shunt surgery in this challenging case of silicone oil refractory glaucoma provided long-term intraocular pressure control and reduced need for medication over a 5-year period.

Propofol Infusion Syndrome in Refractory Status Epilepticus

PubMed Central

Hwang, Woo Sub; Gwak, Hye Min; Seo, Dae-Won

2013-01-01

Background and Purpose: Propofol is used for treating refractory status epilepticus, which has high rate of mortality. Propofol infusion syndrome is a rare but often fatal syndrome, characterized by lactic acidosis, lipidemia, and cardiac failure, associated with propofol infusion over prolonged periods of time. We investigated the clinical factors that characterize propofol infusion syndrome to know the risk of them in refractory status epilepticus. Methods: This retrospective observation study was conducted in Samsung medical center from Jan. 2005 to Dec. 2009. Thirty two patients (19 males, 13 females, aged between 16 and 64 years), with refractory status epilepsy were included. Their clinical findings and treatment outcomes were evaluated retrospectively. We divided our patients into established status epilepticus (ESE) and refractory status epilepticus (RSE). And then the patients with RSE was further subdivided into propofol treatment group (RSE-P) and the other anesthetics treatment group (RSE-O). We analyzed the clinical characteristics by comparison of the groups. Results: There were significant differences of hypotension and lipid change between ESE and RSE (p<0.05). However, there was no significant difference between RSE-P and RSE-O groups. The hospital days were longer in RSE than in ESE (p=0.012) and treatment outcome was also worse in RSE than in ESE (p=0.007) but there were no significant differences of hospital stays and treatment outcome between RSE-P and RSE-O. Conclusions: RSE is very critical disease with high mortality, which may show as many clinical changes as propofol infusion syndrome. Therefore propofol infusion syndrome might be considered as one of the clinical manifestations of RSE. PMID:24649467

2016-01-01

Between 5-40% of autistic patients will develop epilepsy. Most individuals with autism and epilepsy will respond to pharmacologic treatment; however, approximately 20-30% will develop medically refractory epilepsy. For this population, alternative treatments such as ketogenic diet (KD) can be highly efficacious and should be seriously considered. To discuss the use of the KD in refractory pediatric epilepsy and its role in patients with autism and epilepsy. KD is an effective and well-tolerated treatment for refractory childhood epilepsy, including those patients who associate autism and epilepsy. Accurate characterization of the electroclinical epilepsy syndrome is the key to deciding when to consider the KD. Otherwise, the positive effect of KD for treating mitochondrial oxidative disorders and different models of autistic animals suggest that KD could be a good alternative treatment for autistic patients. Based on the demonstrated efficacy of KD in patients who associate both epilepsy and autism, KD treatment has been recently used in the treatment of autism spectrum disorders; however, there is lacking of controlled studies to define the real efficacy of this therapy. A well designed randomized controlled study is needed to determine whether KD is really efficacious for these patients.

Excimer laser therapy and narrowband ultraviolet B therapy for exfoliative cheilitis.

Exfoliative cheilitis is a condition of unknown etiology characterized by hyperkeratosis and scaling of vermilion epithelium with cyclic desquamation. It remains largely refractory to treatment, including corticosteroid therapy, antibiotics, antifungals, and immunosuppressants. We sought to evaluate the safety and efficacy of excimer laser therapy and narrowband ultraviolet B therapy in female patients with refractory exfoliative cheilitis. We reviewed the medical records of two female patients who had been treated unsuccessfully for exfoliative cheilitis. We implemented excimer laser therapy, followed by hand-held narrowband UVB treatments for maintenance therapy, and followed them for clinical improvement and adverse effects. Both patients experienced significant clinical improvement with minimal adverse effects with excimer laser therapy 600-700 mJ/cm 2 twice weekly for several months. The most common adverse effects were bleeding and burning, which occurred at higher doses. The hand-held narrowband UVB unit was also an effective maintenance tool. Limitations include small sample size and lack of standardization of starting dose and dose increments. Excimer laser therapy is a well-tolerated and effective treatment for refractory exfoliative cheilitis with twice weekly laser treatments of up to 700 mJ/cm 2 . Transitioning to the hand-held narrowband UVB device was also an effective maintenance strategy.

We present a case of accidental injection of tranexamic acid during spinal anesthesia for an elective cesarean delivery. Immediately following intrathecal injection of 2mL of solution, the patient complained of severe back pain, followed by muscle spasm and tetany. As there was no evidence of spinal block, the medications given were checked and a 'used' ampoule of tranexamic acid was found on the spinal tray. General anesthesia was induced but muscle spasm and tetany persisted despite administration of a non-depolarizing muscle relaxant. Hemodynamic instability, ventricular tachycardia, and status epilepticus developed, which were refractory to phenytoin, diazepam, and infusions of thiopental, midazolam and amiodarone. Magnesium sulfate was administered postoperatively in the intensive care unit, following which the frequency of seizures decreased, eventually stopping. Unfortunately, on postoperative day three the patient died from cardiopulmonary arrest after an oxygen supply failure that was not associated with the initial event. This report underlines the importance of double-checking medications before injection in order to avoid a drug error. As well, it suggests that magnesium sulfate may be useful in stopping seizures caused by the intrathecal injection of tranexamic acid. Copyright © 2015 Elsevier Ltd. All rights reserved.

Chronic idiopathic intestinal pseudo-obstruction treated by near total small bowel resection: a 20-year experience.

Patients suffering from chronic idiopathic intestinal pseudo-obstruction (CIIPO) clearly benefit from home parenteral nutrition (HPN) to maintain adequate nutritional status and general health. But intestinal dismotility can seriously disturb their quality of life (QOL) to the point of making it intolerable. Report our clinical experience on the management of chronic severe occlusive symptoms in CIIPO by near total small bowel resection. A 20-year retrospective study of eight patients with end-stage CIIPO maintained on HPN and suffering of chronic occlusive symptoms refractory to medical treatment underwent extensive small bowel resection preserving less than 70 cm of total small bowel and less than 20 cm of ileum. The jejunum was anastomosed either to the ileum or to the colon. Six patients were completely relieved from obstructive symptoms. Two patients needed a second operation to remove the residual ileum because of recurrent symptoms. Two were significantly improved. There was no post-operative death. All patients experienced a significant improvement in their QOL. Near total small bowel resection appears to be a safe and effective procedure in end-stage CIIPO patients, refractory to optimal medical treatment.

Korsten, Peter; Mirsaeidi, Mehdi; Sweiss, Nadera J.

2014-01-01

Purpose of review None of the medications used in clinical practice to treat sarcoidosis have been approved by the regulatory authorities. Understanding how to use disease-modifying antisarcoid drugs, however, is essential for physicians treating patients with sarcoidosis. This review summarizes the recent studies of medications used for sarcoidosis with a focus on nonsteroidal therapies. Studies from 2006 to 2013 were considered for review to update clinicians on the most relevant literature published over the last few years. Recent findings Several recently published pieces of evidence have helped expand our ability to more appropriately sequence second-line and third-line therapies for sarcoidosis. For instance, methotrexate and azathioprine may be useful and well tolerated medications as second-line treatment. Mycophenolate mofetil might have a role in neurosarcoidosis. TNF-α blockers and other biologics seem to be well tolerated medications for the most severely affected patients. Summary Corticosteroids remain the first-line therapy for sarcoidosis as many patients never require treatment or only necessitate a short treatment duration. Second-line and third-line therapies described in this article should be used in patients with progressive or refractory disease or when life-threatening complications are evident at the time of presentation.

Refractory status epilepticus is a potentially life-threatening medical emergency. It requires early diagnosis and treatment. There is a lack of consensus upon its semantic definition of whether it is status epilepticus that continues despite treatment with benzodiazepine and one antiepileptic medication (AED), i.e., Lorazepam + phenytoin. Others regard refractory status epilepticus as failure of benzodiazepine and 2 antiepileptic medications, i.e., Lorazepam + phenytoin + phenobarb. Up to 30% patients in SE fail to respond to two antiepileptic drugs (AEDs) and 15% continue to have seizure activity despite use of three drugs. Mechanisms that have made the treatment even more challenging are GABA-R that is internalized during status epilepticus and upregulation of multidrug transporter proteins. All patients of refractory status epilepticus require continuous EEG monitoring. There are three main agents used in the treatment of RSE. These include pentobarbital or thiopental, midazolam and propofol. RSE was shown to result in mortality in 35% cases, 39.13% of patients were left with severe neurological deficits, while another 13% had mild neurological deficits. PMID:24791086

Malignant glaucoma remains one of the most dramatic complications of ocular surgery. It can occur after glaucoma surgery but also after iridotomy, capsulotomy, or cataract extraction. However, the mechanisms remain unclear. to evaluate diode laser cyclodestruction as a complementary treatment in refractory malignant glaucoma. Seven women with malignant glaucoma with onset several months before (mean, 43 months; range, 12-96 months), in whom shallow anterior chamber and high IOP (25 mmHg +/- 5.5 treated with 2.86 +/- 0.9 topical and systemic medications) persisted despite prior surgical treatment (mean, 2; range, 1-5). Controlateral eyes had hyperopia (mean, +3.7 D, range, +1 to +6), five had shallow anterior chamber and high IOP. UBM detected plateau iris in four women. Seven eyes with malignant glaucoma and three controlateral eyes underwent cyclodestruction with diode laser (Viridis Twin Quantel Medical, laser, 810 nm), 22 burns around 270 degrees , 2 mm from the limbus for glaucomatous eyes and 15 inferior burns for controlateral eyes. Resolution of malignant glaucoma, with lower pressure (mean, 35%; range, 10%-70%), lower levels of medications (64%), final IOP at 13.2 mmHg (+/- 4.7), and deepening anterior chamber was achieved in all cases (mean follow-up, 18 months; range, 12-22). Cycloplegic topical treatment was stopped in 70% of cases. Diode laser cyclodestruction can help to resolve refractory malignant glaucoma. Larger UBM studies could help us to better understand the mechanisms of malignant glaucoma.

Despite medication, exercise, and medical intervention, many patients complain of persistent discogenic neck pain. To manage discogenic neck pain, we performed intradiscal pulsed radiofrequency (PRF) stimulation in a patient with chronic discogenic neck pain refractory to oral medication and epidural steroid injection. A 26-year-old man presented with a numeric rating scale (NRS) score of 7 for chronic neck pain. His pain was worse when the neck was held in one position for a prolonged period. There was no pain in the upper extremities. Discography was positive at C4-5. Based on the pain characteristics, and the result of discography, we diagnosed him as having discogenic neck pain originating from C4-5. Intradiscal PRF on the C4-5 intervertebral disc was performed under C-arm fluoroscopy. The PRF treatment was administered at 2 Hz and a 20-ms pulsed width for 20 minutes at 60 V with the constraint that the electrode tip temperature should not exceed 42°C. At the 2-week, and 1-month follow-up visits, the patient's pain was completely relieved. At 2, and 3 months after intradiscal PRF, the pain was scored as NRS 2. No adverse effects of intradiscal PRF stimulation were observed. Application of intradiscal PRF appears to be an effective and safe technique for treating chronic discogenic neck pain.

Office procedures in chronic rhinosinusitis (CRS) can be considered before and after medical management, as well as before and after surgical management. This article focuses specifically on refractory CRS, meaning those patients who have failed medical and surgical management already. The options available in the management of refractory CRS depend on the personnel, equipment, and instrumentation available in the office setting; surgeon experience; and patient suitability and tolerability. This article provides readers with possible procedural options that can be done in their clinics with indications, patient selection, potential complications, and postoperative considerations.

A case of severe refractory chronic urticaria: a novel method for evaluation and treatment.

PubMed

Otto, Hans F; Calabria, Christopher W

2009-01-01

With cholinergic urticaria (ChU), the ultimate diagnosis often depends on the demonstration of characteristic urticaria by appropriate provocation. Several treatment options may be helpful but traditional options (antihistamines, leukotriene inhibitors, and immunosuppressives) may be exhausted by the refractory ChU patient. Here, we describe such a case. Demonstration of immediate hypersensitivity to autologous sweat skin testing (ASwST) may provide a rationale for use of omalizumab (Xolair, Genentech Novartis, South San Francisco, CA). Patients with severe ChU may have difficulty producing sufficient quantities of sweat for ASwST given that the very effort that produces the sample exacerbates ChU. Generation of sweat by iontophoresis with pilocarpine nitrate can be performed at many large medical centers. The procedure is simple, safe, and produces varying amounts of sweat depending on the individual. This sweat can then be used for ASwST. Our patient had a positive ASwST with appropriate positive and negative controls. Our testing methods were validated by negative ASwST, saline control, and positive histamine control in a nonatopic, nonurticarial control patient. By the patient's second injection of omalizumab, her quality of life score was significantly improved, as were her daily medication scores and exercise tolerance. We describe the first case of a patient with severe refractory ChU who had a positive ASwST by a novel collection method who has been successfully treated with omalizumab. We present a novel tool for the evaluation and demonstration of sweat-specific IgE in ChU patients who are unable to provide sweat by more traditional means.

Loeffler Endocarditis: A Unique Presentation of Right-Sided Heart Failure Due to Eosinophil-Induced Endomyocardial Fibrosis.

PubMed

Alam, Amit; Thampi, Shankar; Saba, Shahryar G; Jermyn, Rita

2017-01-01

Loeffler endocarditis is a rare restrictive cardiomyopathy caused by abnormal endomyocardial infiltration of eosinophils, with subsequent tissue damage from degranulation, eventually leading to fibrosis. Although an uncommon entity, it is still a disease with significant morbidity and mortality. Often identified only at late stages, treatment options are limited once fibrosis occurs, usually requiring heart failure medications or surgical intervention. We present a unique case of a woman with remote history of hypereosinophilic syndrome, attributed to treatment of rheumatoid arthritis with infliximab, who presented with symptoms of heart failure refractory to medical management and was found to have Loeffler endocarditis. The severe progression of the disease required surgical intervention with endocardial stripping to treat the right-sided diastolic heart failure.

Background More data is needed to guide next step interventions for panic disorder refractory to initial intervention. Method This 24-week randomized clinical trial (RCT) consisted of three phases. Phase 1 is a 6-week lead-in with open-label sertraline flexibly dosed to 100mg (or escitalopram equivalent) to prospectively define treatment refractoriness (lack of remission). Phase 2 is a six-week double blind RCT of (1) increased dose serotonin selective reuptake inhibitor (SSRI) versus (2) continued SSRI plus placebo. Phase 3 is a 12-week RCT of added cognitive-behavioral therapy (CBT) compared to “medication-optimization” (MO) with SSRI plus clonazepam. Primary endpoints were remission and change in Panic Disorder Severity Scale (PDSS) score in the intent to treat sample in each phase. Results In Phase 1, 20.5% (8/39) achieved remission, and only baseline severity predicted endpoint PDSS (β (SE)= 1.04(0.15), t=6.76, p<0.000). In Phase 2, increasing the SSRI dose did not result in greater improvement or remission rates (placebo 15% [n=2] vs. increased dose 9%[n=1]: FET p=n.s.). In Phase 3, remission was minimal (MO = 11%; CBT =10%), with a lack of group difference in PDSS reduction (t(df)=0.51(17), p>0.60) consistent with a small effect size (d=0.24). Conclusion Although power was limited and larger studies are needed, we failed to find evidence for greater benefit of increased SSRI dose versus continuation of current dose for panic disorder symptomatic after 6 weeks at moderate dose. Further, augmentation with CBT or medication optimization with clonazepam augmentation in non-remitted panic after 12 weeks of an SSRI did not differ, suggesting both are reasonable next-step options. However, low overall remission rates in this comorbid refractory population suggest better predictors of response to specific treatments over time and additional interventions are needed.

This study was done to investigate the efficacy and safety of percutaneous renal denervation with the Symplicity catheter for reducing blood pressure in patients with essential hypertension resistant to medical therapy (systolic blood pressure >160 mmHg despite the use of three or more antihypertensive drugs, including a diuretic). In September 2010, five patients affected by essential hypertension resistant to medical therapy were treated. All patients were studied by computed tomography angiography (CTA) of the renal arteries before the procedure and underwent follow-up at 30 and 60 days with colour Doppler ultrasound (CDUS) with evaluation of resistive index, glomerular filtration rate (GFR), 24-h blood pressure and serum catecholamine concentration. Student's t test was used to assess the effectiveness of the procedure in lowering blood pressure. In treated patients, mean blood pressure at baseline was 171/100 mmHg [standard deviation (SD) ± 8/10]; mean GFR was 91.6 ml/min/1.73 m(2) (SD ± 15). Blood pressure after the procedure was reduced by -18/-5 and -13/-10 mmHg at 30 and 60 days, respectively, with a mean medication reduction of 3.6. No complications occurred during the intra- or periprocedural period or during short-term follow-up. The Symplicity system proved to be efficacious and without serious adverse events in reducing blood pressure and antihypertensive medication use in patients affected by essential hypertension resistant to medical therapy. Although encouraging, our data are preliminary and need to be validated by larger prospective randomised studies.

To evaluate the efficacy and safety of lacosamide in pediatric patients with refractory focal epilepsy. We reviewed retrospectively the medical records of children younger than 18 years of age treated at Seoul National University Bundang Hospital, in whom oral lacosamide was used as an adjunctive treatment for refractory focal epilepsy. Clinical information regarding the patients' epilepsy and the outcome of lacosamide treatment was gathered and analyzed. Twenty-one patients (16 boys, 5 girls) were included, with a median age of 13.9 (range, 1.2-17.9) years. The mean number of concomitant antiepileptic drugs was 3.0 (range, 1-6) and the mean duration of follow-up was 10.1 (range, 6.1-13.0) months. The mean maintenance dose of lacosamide was 5.4 (range, 1.4-9.8) mg/kg/day. Fourteen patients (67%) were responders; four of these were seizure free at the last follow-up. Seven patients (33%) were nonresponders: two of these presented with <50% seizure reduction and five showed no change in seizure frequency. Two patients (10%) discontinued oral lacosamide because of adverse events (aggressive behavior and depression). Mild transient treatment-related adverse events were observed in eight of the 21 patients (38%). Lacosamide represents a useful drug that is effective for a wide range of pediatric refractory focal epilepsy and is well tolerated. Copyright © 2013 The Japanese Society of Child Neurology.

More than 25 % of children with epilepsy develop refractory seizures unresponsive to both old and new generation anticonvulsants. Since such seizures have a serious negative impact on the quality of life, other treatment options are considered. The ketogenic diet is a well-known treatment for managing refractory seizures, although its mechanism of action is unknown. Studies have shown that this diet is as good as, or better than, any of the newer medications in reducing seizure frequency. However, concerns about adverse effects have been raised. We conducted an open label trial to show the effects of this diet on serum lipid profile. Thirty-three children with refractory epilepsy were treated with the ketogenic diet and were followed for 6 months. Their serum lipid profile was assessed at baseline, and at 3 and 6 months after initiating the diet. Seizure frequency was reduced in 63 % of children (no seizures in 2/33 and reduced >50 % in 19/33). However, after 6 months of administering the diet, median triglyceride was significantly increased (from 84 to 180 mg/dl, P < 0.001), median total cholesterol was significantly increased (from 180 to 285 mg/dl, P < 0.001), median serum low-density lipoprotein (LDL) was significantly increased (from 91 to 175 mg/dl, P < 0.001), and median serum high-density lipoprotein (HDL) was significantly increased (from 51 to 58 mg/dl, P < 0.001). Results of this study indicate that a classic ketogenic diet in children with refractory seizures is effective in seizure reduction, but leads to development of hypercholesterolemia and hypertriglyceridemia.

A majority of patients with advanced or metastatic non-small cell lung cancer (NSCLC) will experience disease progression after first-line therapy. Patients who have advanced NSCLC that is especially aggressive, which is defined as disease that rapidly progresses on first-line treatment or disease that is refractory to first-line treatment, have a critical unmet medical need. These patients have a poor prognosis in the second-line setting. Several studies have recently shown that treatment with an antiangiogenic therapy may benefit these patients. This review summarizes the approved antiangiogenic therapies for the treatment of patients with advanced NSCLC in the second-line setting, specifically focusing on the outcomes from subgroups of patients with rapidly progressing or refractory disease. Several antiangiogenic agents, as monotherapy or in combination with other treatments, have been or are currently being studied in patients with advanced NSCLC. Antiangiogenics that are approved for use in patients with advanced NSCLC are limited to bevacizumab in combination with chemotherapy (nonsquamous NSCLC), ramucirumab in combination with docetaxel (all histologies), and nintedanib in combination with docetaxel (adenocarcinoma histology). This review focuses on the efficacy, safety, and quality of life outcomes in the subpopulation of patients with rapidly progressing or refractory NSCLC treated with approved antiangiogenic therapies in the second-line setting. We also discuss the impact of newly approved immunotherapy agents on the outcomes of patients with aggressive or refractory disease. Studies in progress and planned future research will determine if combination treatment with antiangiogenics and immunotherapies will benefit patients with aggressive, advanced NSCLC.

BACKGROUND: Pseudofolliculitis barbae affects some individuals with coarse curly hair. Currently available treatment modalities are often ineffective. In some studies, lasers have been shown to be potentially helpful in mitigating disease severity by reducing the number and/or thickness of hair shafts. METHODS: This was a side-by-side interventional study conducted at a military tertiary medical facility. The study group included 26 patients (skin types IV, V, and VI) referred from primary care physicians with a diagnosis of pseudofolliculitis barbae refractory to medical therapy. A neodymium YAG laser was used to treat one half of the neck. One month later, shaving bumps were counted and compared to their preoperative levels on both sides. RESULTS: Mean postoperative papule counts were 11.6 +/- 6 (SD) and 30.1 +/- 19 (SD) on the treated side and untreated sides, respectively. CONCLUSION: Neodymium YAG laser treatment represents a safe and effective option for reducing papule formation in patients with pseudofolliculitis barbae. Images Figure 1 PMID:12408693

Successful treatment of hyperphagia by resection of a hypothalamic hamartoma.

Esquenazi, Yoshua; Sandberg, David I; Rekate, Harold L

2013-06-01

Hypothalamic hamartomas (HHs) are benign lesions that are often associated with central precocious puberty and may present with gelastic seizures. Treatment modalities for HH include medical therapy with long-term gonadotropin-releasing hormone analogs or resection. The authors report the case of a 7-year-old girl who was diagnosed with an HH due to precocious puberty and was treated medically with a gonadotropin-releasing hormone analog for 3 years. Despite normalization of her plasma levels of luteinizing hormone, follicle-stimulating hormone, and estradiol and arrest of her precocious puberty, the patient developed progressive weight gain associated with extreme hyperphagia and morbid obesity by the age of 10 years. Her compulsive eating patterns were refractory to counseling and other interventions attempted by her parents and physicians. After resection of the HH, her hyperphagia resolved and her weight stabilized. To the authors' knowledge, this is the first report describing resection of an HH for the purpose of treating hyperphagia and obesity.

Ipilimumab is used for the treatment of metastatic melanoma and is associated with serious immune-related colitis. We aimed to report the clinical features, treatment, and outcomes of patients with ipilimumab-induced colitis. In this retrospective observational study, we identified patients with unresectable melanoma treated with ipilimumab between March 2011 and September 2013. Diarrhea was assessed using the Common Terminology Criteria for Adverse Events, v3.0. Colitis was defined by diarrhea (grade≥2) requiring steroids with or without endoscopic/histologic/radiologic evidence of colitis. A total of 103 patients with metastatic melanoma treated with ipilimumab were identified. Of these, 30 patients (29%) developed diarrhea (all grades), and 23 patients (22%) developed colitis requiring systemic corticosteroid therapy. The median number of ipilimumab doses before onset of diarrhea was 2 (range, 1-4). Six of 23 patients responded to less than 1 mg/kg daily prednisone alone. Fifteen patients required high-dose oral and/or intravenous prednisone (1-2 mg/kg body weight). Six patients had diarrhea refractory to prednisone; five required rescue therapy with budesonide (9-12 mg daily) and one was treated with infliximab (5 mg/kg, three doses). There was one case of severe diarrhea (grade 3) treated successfully with high-dose budesonide (12 mg) monotherapy. Ipilimumab-induced colitis requires early and aggressive medical therapy. Most patients can be successfully managed with systemic corticosteroids. High-dose budesonide is an attractive steroid-sparing agent, however further studies of its efficacy in this setting are needed. Infliximab should be used in refractory cases to avoid colectomy.

Hyperbaric oxygen treatment for inflammatory bowel disease: a systematic review and analysis

PubMed Central

2012-01-01

Background Traditionally, hyperbaric oxygen treatment (HBOT) has been used to treat a limited repertoire of disease, including decompression sickness and healing of problem wounds. However, some investigators have used HBOT to treat inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. Methods Comprehensive searches were conducted in 8 scientific databases through 2011 to identify publications using HBOT in IBD. Human studies and animal models were collated separately. Results Thirteen studies of HBOT in Crohn's disease and 6 studies in ulcerative colitis were identified. In all studies, participants had severe disease refractory to standard medical treatments, including corticosteroids, immunomodulators and anti-inflammatory medications. In patients with Crohn's disease, 31/40 (78%) had clinical improvements with HBOT, while all 39 patients with ulcerative colitis improved. One study in Crohn's disease reported a significant decrease in proinflammatory cytokines (IL-1, IL-6 and TNF-alpha) and one study in ulcerative colitis reported a decrease in IL-6 with HBOT. Adverse events were minimal. Twelve publications reported using HBOT in animal models of experimentally-induced IBD, including several studies reporting decreased markers of inflammation or immune dysregulation, including TNF-alpha (3 studies), IL-1beta (2 studies), neopterin (1 study) and myeloperoxidase activity (5 studies). HBOT also decreased oxidative stress markers including malondialdehyde (3 studies) and plasma carbonyl content (2 studies), except for one study that reported increased plasma carbonyl content. Several studies reported HBOT lowered nitric oxide (3 studies) and nitric oxide synthase (3 studies) and one study reported a decrease in prostaglandin E2 levels. Four animal studies reported decreased edema or colonic tissue weight with HBOT, and 8 studies reported microscopic improvements on histopathological examination. Although most publications reported improvements with HBOT, some studies suffered from limitations, including possible publication and referral biases, the lack of a control group, the retrospective nature and a small number of participants. Conclusions HBOT lowered markers of inflammation and oxidative stress and ameliorated IBD in both human and animal studies. Most treated patients were refractory to standard medical treatments. Additional studies are warranted to investigate the effects of HBOT on biomarkers of oxidative stress and inflammation as well as clinical outcomes in individuals with IBD. PMID:22417628

Background Recurrent head and neck squamous cell carcinoma (HNSCC) remains a difficult cancer to treat. Here, we describe a patient with HNSCC who had complete response to methotrexate (MTX) after progressing on multiple cytotoxic agents, cetuximab, and AMG-479 (monoclonal antibody against insulin-like growth factor-1 receptor [IGF-1R]). Methods The clinical information was collected by a retrospective medical record review under an Institutional Review Board–approved protocol. From 4 tumors and 2 normal mucosal epithelia, global gene expression, and IGF-1R and dihydrofolate reductase (DHFR) protein levels were determined. Results Effective target inhibition in the tumor was confirmed by the decreased protein levels of total and phospho-IGF-1R after treatment with AMG-479. Decreased level of DHFR and conversion of a gene expression profile associated with cetuximab-resistance to cetuximab-sensitivity were also observed. Conclusion This suggests that the combination of AMG- 479 and MTX or cetuximab may be a promising therapeutic approach in refractory HNSCC. PMID:20652976

Stem cell transplant in inflammatory bowel disease: a promising modality of treatment for a complicated disease course.

PubMed

Salem, George A; Selby, George B

2017-01-01

Inflammatory bowel disease (IBD) is a complex, relapsing and remitting, disease characterized by an exaggerated immune response in a susceptible host. The symptoms and complications of the disease can be debilitating. Advances in medical treatment in the last decade changed the course of the disease in many patients. Despite the use of novel agents for controlling disease, a proportion of patients' disease courses continue to be either refractory, or become resistant, to available therapeutic options. Stem-cell therapy, with hematopoietic stem cells (HSCs) or mesenchymal stem cells (MSCs), is a promising modality of treatment for severe refractory cases, mainly Crohn's disease (CD) patients. HSCs have the ability to migrate to damaged tissue, which provides them with further properties to differentiate to epithelial or immune-modulatory cells to restore normal mucosal tissue and integrity. MSCs therapy is a promising model for patients with perianal CD due to their immunosuppressive properties, ability to migrate to areas of injury, and demonstration of colonic healing, including fistulizing tracts. The results from ongoing clinical trials will provide a valuable understanding of the future of stem-cell therapy as a treatment option in refractory cases of IBD, a disease whose pathogenesis remains unknown, and is notoriously difficult to treat.

Medical treatment has progressed significantly over the past decade towards achieving and maintaining clinical remission in patients with refractory ulcerative colitis (UC). Proposed mediators of inflammation in UC include pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-2, and the cell-surface adhesive molecule integrin α4β7. Conventional therapeutics for active UC include 5-aminosalicylic acid, corticosteroids and purine analogues (azathioprine and 6-mercaptopurine). Patients who fail to respond to conventional therapy are treated with agents such as the calicineurin inhibitors cyclosporine and tacrolimus, the TNF-α inhibitors infliximab or adalimumab, or a neutralizing antibody (vedolizumab) directed against integrin α4β7. These therapeutic agents are of benefit for patients with refractory UC, but are not universally effective. Our recent research on TNF-α shedding demonstrated that inhibition of annexin (ANX) A2 may be a new therapeutic strategy for the prevention of TNF-α shedding during inflammatory bowel disease (IBD) inflammation. In this review, we provide an overview of therapeutic treatments that are effective and currently available for UC patients, as well as some that are likely to be available in the near future. We also propose the potential of ANX A2 as a new molecular target for IBD treatment. PMID:26269667

AIM To evaluate the long-term results and complications of Ahmed glaucoma valve (AGV) implantation in a cohort of Egyptian patients. METHODS A retrospective study of 124 eyes of 99 patients with refractory glaucoma who underwent AGV implantation and had a minimum follow-up of 5y was performed. All patients underwent complete ophthalmic examination and intraocular pressure (IOP) measurement before surgery and at 1d, weekly for the 1st month, 3, 6mo, and 1y after surgery and yearly afterward for 5y. IOP was measured by Goldmann applanation tonometry and/or Tono-Pen. Complications and the number of anti-glaucoma medications needed were recorded. Success was defined as IOP less than 21 mm Hg with or without anti-glaucoma medication and without additional glaucoma surgery. RESULTS Mean age was 23.1±19.9y. All eyes had at least one prior glaucoma surgery. IOP was reduced from a mean of 37.2±6.8 to 19.2±5.2 mm Hg after 5y follow-up with a reduced number of medications from 2.64±0.59 to 1.81±0.4. Complete and qualified success rates were 31.5% and 46.0% respectively at the end of follow-up. The most common complications were encapsulated cyst formation in 51 eyes (41.1%), complicated cataract in 9 eyes (7.25%), recessed tube in 8 eyes (6.45%), tube exposure in 6 eyes (4.8%) and corneal touch in 6 eyes (4.8%). Other complications included extruded AGV, endophthalmitis and persistent hypotony. Each of them was recorded in only 2 eyes (1.6%). CONCLUSION Although refractory glaucoma is a difficult problem to manage, AGV is effective and relatively safe procedure in treating refractory glaucoma in Egyptian patients with long-term follow-up. Encapsulated cyst formation was the most common complication, which limits successful IOP control after AGV implantation. However, effective complications management can improve the rate of success.

Ketamine is an emerging therapy for pediatric refractory status epilepticus. The circumstances of its use, however, are understudied. The authors described pediatric refractory status epilepticus treated with ketamine from 2010 to 2014 at 45 centers using the Pediatric Hospital Inpatient System database. For comparison, they described children treated with pentobarbital. The authors estimated that 48 children received ketamine and pentobarbital for refractory status epilepticus, and 630 pentobarbital without ketamine. Those receiving only pentobarbital were median age 3 [interquartile range 0-10], and spent 30 [18-52] days in-hospital, including 17 [9-28] intensive care unit (ICU) days; 17% died. Median cost was $148 000 [81 000-241 000]. The pentobarbital-ketamine group was older (7 [2-11]) with longer hospital stays (51 [30-93]) and more ICU days (29 [20-56]); 29% died. Median cost was $298 000 [176 000-607 000]. For 71%, ketamine was given ≥1 day after pentobarbital. Ketamine cases per half-year increased from 2 to 9 ( P < .05). Ketamine is increasingly used for severe pediatric refractory status epilepticus, typically after pentobarbital. Research on its effectiveness is indicated.

Optimal salvage chemotherapy regimen for patients with relapsed or refractory Hodgkin and non-Hodgkin lymphoma remains unclear but often based on platinum regimens. This retrospective study assesses in real life the toxicities profiles of patients with relapsed or refractory lymphoma treated with DHA (dexamethasone, high dose aracytine cytarabine) plus platinum salt (dexamethasone-High dose aracytine (cis)platin (DHAP), dexamethasone-High dose aracytine carboplatin (DHAC), or dexamethasone-High dose aracytine Oxaliplatin (DHAOX)), from February 2007 to May 2013 in 2 French hospitals. Toxicities were recorded from medical files and assessed according to the National Cancer Institute Common Toxicity Criteria version 3.0. Potential risk factors of renal insufficiency were tested by univariate analyses. A total of 276 patients were treated: 168 with DHAP (60.9%), 79 with DHAOX (28.6%), and 29 with DHAC (10.5%). Rituximab was associated in 80.1% of patients (n = 221). Renal failure was reported in 97 patients, mainly with cisplatin regimen (86.6%) leading to 8.9% grade III to IV renal failure (P = .001). Renal insufficiency was reversible in most patients but remained persistent in 24, with all of them being treated with DHAP except 1. Cisplatin-based regimen (50.0% versus 12.0%, P < .05) and female (44.6% versus 29.7%, P < .05) appeared to be at higher risks of renal failure. Platinum cumulative dose is a significant risk factor of nephrotoxicity. Hematologic toxicity was more frequent with carboplatin and cisplatin with at least 1 event (all toxicity grade) respectively in 79.3% and 71.4% of patients treated (P < .005). Auditory toxicity was mainly reported with cisplatin (n = 19; 4 grade I-II and 15 grade III-IV). Oxaliplatin was implicated in 77.6% of neurotoxicity (n = 59), mainly moderate (grade I-II). In conclusion, DHAOX and DHAC regimens have more favorable toxicity profile than DHAP regimen. Their lack of renal toxicity makes them attractive regimens, which may be interesting for patients eligible for autologous stem cell transplantation. Nevertheless, these results have to be confirmed by the therapeutic efficacy of these 3 regimens. Copyright © 2016 John Wiley & Sons, Ltd.

The ketogenic diet (KD) is currently a well-established treatment for patients with medically refractory, nonsurgical epilepsy. However, despite its efficacy, the KD is highly restrictive and constitutes a treatment with serious potential adverse effects, and often with difficulties in its implementation and compliance. Patients on the KD require strict follow-up and constant supervision by a medical team highly experienced in its management in order to prevent complications. Other alternative treatments for patients with refractory epilepsy include vagus nerve stimulation (VNS), new-generation antiepileptic drugs (AEDs), corpus callosotomy (CC), and responsive focal cortical stimulation (RNS). In this review, we explain not only the difficulties of the KD as a therapeutic option for refractory epilepsy but also the benefits of other therapeutic strategies, which, in many cases, have proven to have better efficacy than the KD itself.

Mantle-cell lymphoma is an aggressive B-cell lymphoma with a poor prognosis. Both ibrutinib and temsirolimus have shown single-agent activity in patients with relapsed or refractory mantle-cell lymphoma. We undertook a phase 3 study to assess the efficacy and safety of ibrutinib versus temsirolimus in relapsed or refractory mantle-cell lymphoma. This randomised, open-label, multicentre, phase 3 clinical trial enrolled patients with relapsed or refractory mantle-cell lymphoma confirmed by central pathology in 21 countries who had received one or more rituximab-containing treatments. Patients were stratified by previous therapy and simplified mantle-cell lymphoma international prognostic index score, and were randomly assigned with a computer-generated randomisation schedule to receive daily oral ibrutinib 560 mg or intravenous temsirolimus (175 mg on days 1, 8, and 15 of cycle 1; 75 mg on days 1, 8, and 15 of subsequent 21-day cycles). Randomisation was balanced by using randomly permuted blocks. The primary efficacy endpoint was progression-free survival assessed by a masked independent review committee with the primary hypothesis that ibrutinib compared with temsirolimus significantly improves progression-free survival. The analysis followed the intention-to-treat principle. The trial is ongoing and is registered with ClinicalTrials.gov (number NCT01646021) and with the EU Clinical Trials Register, EudraCT (number 2012-000601-74). Between Dec 10, 2012, and Nov 26, 2013, 280 patients were randomised to ibrutinib (n=139) or temsirolimus (n=141). Primary efficacy analysis showed significant improvement in progression-free survival (p<0·0001) for patients treated with ibrutinib versus temsirolimus (hazard ratio 0·43 [95% CI 0·32-0·58]; median progression-free survival 14·6 months [95% CI 10·4-not estimable] vs 6·2 months [4·2-7·9], respectively). Ibrutinib was better tolerated than temsirolimus, with grade 3 or higher treatment-emergent adverse events reported for 94 (68%) versus 121 (87%) patients, and fewer discontinuations of study medication due to adverse events for ibrutinib versus temsirolimus (9 [6%] vs 36 [26%]). Ibrutinib treatment resulted in significant improvement in progression-free survival and better tolerability versus temsirolimus in patients with relapsed or refractory mantle-cell lymphoma. These data lend further support to the positive benefit-risk ratio for ibrutinib in relapsed or refractory mantle-cell lymphoma. Janssen Research & Development, LLC. Copyright © 2016 Elsevier Ltd.

Gamma knife surgery for refractory postherpetic trigeminal neuralgia: targeting in one session both the retrogasserian trigeminal nerve and the centromedian nucleus of the thalamus.

PubMed

Keep, Marcus F; DeMare, Paul A; Ashby, Lynn S

2005-01-01

The authors tested the hypothesis that two targets are needed to treat postherpetic trigeminal neuralgia (TN): one in the trigeminal nerve for the direct sharp pain and one in the thalamus for the diffuse burning pain. Three patients with refractory postherpetic TN were treated with gamma knife surgery (GKS) through a novel two-target approach. In a single treatment session, both the trigeminal nerve and centromedian nucleus were targeted. First, the trigeminal nerve, ipsilateral to the facial pain, was treated with 60 to 80 Gy. Second, the centromedian nucleus was localized using standard coordinates and by comparing magnetic resonance images with a stereotactic atlas. A single dose of 120 to 140 Gy was delivered to the target point with a single 4-mm isocenter. Patients were followed clinically and with neuroimaging studies. Pain relief was scored as excellent (75-100%), good (50-75%), poor (25-50%); or none (0-25%). Follow up ranged from 6 to 53 months. There were no GKS-related complications. Two patients died of unrelated medical illnesses but had good or excellent pain relief until death. One patient continues to survive with 44 months follow up and no decrease in pain intensity, but with a decreased area of pain. Combined GKS of the centromedian nucleus and trigeminal nerve in a single treatment session is feasible and safe, and the effect was promising. A larger study is required to confirm and expand these results.

Summary A 67-year-old man with medically refractory vertebrobasilar insufficiency and short segment occlusions of the intracranial vertebral arteries was treated with angioplasty and stent placement. Fifteen hours after the procedure the patient developed symptoms of posterior fossa ischemia and repeat angiography showed thrombus formation within the stent which was treated with thrombolytic and aggressive antiplatelet therapy. Angiography revealed lysis of the clot, but concerns regarding the mechanism of the thrombotic phenomenon prompted frequency-domain optical coherence tomography (FDOCT) assessment. FDOCT provided excellent visualization of the stent and vessel wall interactions, as well as excluding residual flow-limiting stenosis, obviating the need for further intervention. The potential utility of FDOCT in the evaluation of intracranial atherosclerotic disease and additional intracranial applications are discussed. PMID:24835808

Aggression, self-injurious behavior, and severe tantrums are impairing symptoms frequently experienced by individuals with autism spectrum disorders. Despite US Food and Drug Administration approval of two atypical antipsychotics targeting these symptoms in youth with autistic disorder, they remain frequently drug refractory. We define drug-refractory aggression, self-injurious behavior, and severe tantrums in people with autism spectrum disorders as behavioral symptoms requiring medication adjustment despite previous trials of risperidone and aripiprazole or previous trials of three psychotropic drugs targeting the symptom cluster, one of which was risperidone or aripiprazole. We reviewed the medical records of individuals of all ages referred to our clinic for autism spectrum disorder diagnostic evaluation, as well as pharmacotherapy follow-up notes for all people meeting autism spectrum disorder criteria, for drug-refractory symptoms. Among 250 consecutively referred individuals, 135 met autism spectrum disorder and enrollment criteria, and 53 of these individuals met drug-refractory symptom criteria. Factors associated with drug-refractory symptoms included age 12 years or older (p < 0.0001), diagnosis of autistic disorder (p = 0.0139), and presence of intellectual disability (p = 0.0273). This pilot report underscores the significance of drug-refractory aggression, self-injurious behavior, and severe tantrums; suggests the need for future study clarifying factors related to symptom development; and identifies the need for focused treatment study of this impairing symptom domain. © The Author(s) 2014.

Refractory hypertension is an extreme phenotype of antihypertensive treatment failure. Participants in the REasons for Geographic And Racial Differences in Stroke (REGARDS) Study, a large (n=30,239), population-based cohort were evaluated to determine the prevalence of refractory hypertension and associated cardiovascular risk factors and comorbidities. Refractory hypertension was defined as uncontrolled blood pressure (systolic/diastolic ≥ 140/90 mm Hg) on ≥ 5 antihypertensive drug classes. Participants with resistant hypertension (systolic/diastolic ≥140/90 mm Hg on ≥ 3 or<140/90 mm Hg on ≥ 4 antihypertensive classes) and all treated hypertensive participants served as comparator groups. Of 14,809 REGARDS participants receiving antihypertensive treatment, 78 (0.5%) had refractory hypertension. The prevalence of refractory hypertension was 3.6% among participants with resistant hypertension(n=2,144) and 41.7% among participants on 5 or more antihypertensive drug classes. Among all hypertensive participants, African American race, male gender, living in the stroke belt or buckle, higher body mass index, lower heart rate, reduced estimated glomerular filtration rate, albuminuria, diabetes and history of stroke and coronary heart disease were associated with refractory hypertension. Compared to resistant hypertension, prevalence ratios for refractory hypertension were increased for African Americans (3.00, 95% CI 1.68 – 5.37) and those with albuminuria (2.22, 95% CI 1.40 – 3.52) and diabetes (2.09, 95% CI 1.32 – 3.31). The median 10-year Framingham risk for coronary heart disease and stroke was higher among participants with refractory hypertension compared to either comparator group. These data indicate that while resistant hypertension is relatively common among treated hypertensive patients, true antihypertensive treatment failure is rare. PMID:24324035

Anal fistulas are a common manifestation of Crohn’s disease (CD). The first manifestation of the disease is often in the peri-anal region, which can occur years before a diagnosis, particularly in CD affecting the colon and rectum. The treatment of peri-anal fistulas is difficult and always multidisciplinary. The European guidelines recommend combined surgical and medical treatment with biologic drugs to achieve best results. Several different surgical techniques are currently employed. However, at the moment, none of these techniques appear superior to the others in terms of healing rate. Surgery is always indicated to treat symptomatic, simple, low intersphincteric fistulas refractory to medical therapy and those causing disabling symptoms. Utmost attention should be paid to correcting the balance between eradication of the fistula and the preservation of fecal continence. PMID:25309057

Background Chronic urticaria (CU) is a common disorder characterized by recurrent episodes of urticaria pruritic erythematous lesions, associated with angioedema1. It affects 0.1% of the population, it is estimated that approximately 15 to 25% of the population will have hives at some point in their lives.2 About 80% of UC patients are diagnosed as idiopathic chronic urticaria and that no cause is identified, 3 experiencing deterioration in their quality of life affecting your work, social relationships, schemes requiring multiple medications and doses higher than usual. This study proposes Omalizumab (anti-IgE humanized antibody) as a treatment for Refractory Chronic Urticaria (RCU) Object Demonstrate Omalizumab's effectiveness in the treatment of Refractory Chronic Urticaria. Methods A clinical study, was carried out to evaluate the effectiveness of the Omalizumab's treatment on RCU diagnosed patient, including male and female patients ages 12 to 50 diagnosed with RCU, with Scorad higher tan 30 points. We made a questionnaire to know about the patient's family background, skin symptoms beginning, administration of drugs such sistemic steroids, inmunosupresors, calceurine inhibitors, presence of inmunotherapy and age of start. Omalizumab was administered on doses according patient's weight and IgE levels, bimonthly or monthly according to treatment guides. Severeness level was calculated with scorad every 1 month, with IgE seric level measurement and life quality questionnaire. Results 5 patients diagnosed with RCU were included in the group of Omalizumab and 5 patients in the control group (placebo). All patients were female. A gradual decrease on the life quality score and in Score, with a significant P under 0.05 was observed on all patients treated with omalizumab compared with patient in the group with placebo. Conclusions Treatment with Omalizumab progressively decreases the severeness level on RCU, with a significant improvement on the patient's life quality.

Endolymphatic sac decompression surgery (ELSD) may be used to treat patients who have Menière's 's disease refractory to medical therapy. In this study, we investigated whether or not the injection of steroid into the endolymphatic sac at the time of ELSD provides additional benefit to patient outcomes. Randomized prospective single-blinded placebo-controlled study. Tertiary center. Patients with Menière's disease with poorly controlled vertigo despite medical therapy and serviceable hearing that were offered ELSD. Patients randomized into two groups, with control group (n = 17) undergone ELSD without steroid injection and experimental group undergone ELSD with steroid injection (n = 18) MAIN OUTCOME MEASURE(S):: Audiogram, dizziness handicap inventory, tinnitus handicap inventory, frequency of vertigo spells, functional level scale, and quality of life were obtained at multiple intervals from preoperatively to 24 months postoperatively. ELSD resulted in a statistically significant improvement in vertigo control whether or not steroid was injected into the endolymphatic sac at the time of surgery. However, no additional benefit was observed with the addition of intra-sac steroid injection. No statistical difference in pure-tone average, tinnitus handicap inventory, dizziness handicap inventory, or quality of life was observed between the steroid and nonsteroid surgical groups up to 24 months postoperatively. ELSD is an effective treatment for Menière's disease refractory to medical therapy; however, the addition of intra-sac steroid injection at the time of surgery does not seem to result in a further improvement in patient outcomes.

2018-04-01

Many treatment techniques have been used for refractory lumbar facet joint pain; however, their efficacy has been controversial. In this study, we investigated the clinical efficacy and safety of intra-articular pulsed radiofrequency for the treatment of refractory lumbar facet joint pain in patients with low back pain. Twenty patients with refractory lumbar facet joint pain were recruited, and each patient was treated via intra-articular pulsed radiofrequency. The treatment effects were measured with a numerical rating scale, and the technical accuracy of intra-articular pulsed radiofrequency treatment was evaluated independently by 2 radiologists. Any adverse events or complications also were checked. We performed intra-articular pulsed radiofrequency treatment at 48 levels of the lumbar facet joints in 20 patients (5 men and 15 women; mean age, 64.50 ± 10.65 years) with refractory lumbar facet joint pain. Pain scores were significantly reduced at 1 month, 3 months, and 6 months after treatment (P < 0.05). The face validity revealed good intraarticular pulsed radiofrequency results in all 20 patients, without any serious adverse effects. Treatment using intra-articular pulsed radiofrequency is an alternative to other techniques in patients with refractory lumbar facet joint pain. Copyright © 2018 Elsevier Inc. All rights reserved.

Ulcerative colitis (UC) is a chronic nonspecific inflammation mainly involving rectum and colon mucosa, which seriously affects the health and quality of life of patients, and is listed as one of modern refractory diseases by WHO. Professor XU Jing-fan, a great master of traditional Chinese medicine, has accumulated rich experiences in the treatment of UC. The study collected Professor XU's 77 prescriptions of treating UC, analyzed the frequency of traditional Chinese medicines and there categories, and investigated the medication regularity by the system clustering method. The findings showed that the most frequently used drugs were clearing-heat herbs, which were followed by hemostatic herbs, excreting-dampness herbs, improving-digestion herbs and tonifying-Qi herbs. At the same time, the commonly combined drugs were excavated. Finally, in order to analyze potential molecular targets of the frequently used herbs, GO enrichment analysis and KEGG signal pathway enrichment analysis were performed with bioinformatics analysis tool for molecular mechanism of traditional Chinese medicine (BATMAN-TCM). The results indicated that Chinese herbal compounds may treat UC by activating PPAR-γ pathway and regulating intestinal inflammation. The exact mechanisms shall be verified through subsequent molecular biological experiments. Copyright© by the Chinese Pharmaceutical Association.

Evidence-based pharmacotherapy of post-traumatic stress disorder (PTSD).

PubMed

Ipser, Jonathan C; Stein, Dan J

2012-07-01

Post-traumatic stress disorder (PTSD) is a prevalent and disabling disorder. Recognition of neurobiological abnormalities associated with this condition suggests the potential efficacy of medication in its treatment. Nevertheless, questions regarding the efficacy of medications remain, despite general endorsement by clinical practice guidelines of selective serotonin reuptake inhibitors (SSRIs) as first-line agents in treating PTSD. This paper reviews evidence from randomized controlled trials (RCTs) for the efficacy of acute and long-term pharmacotherapy for PTSD, including the treatment of refractory PTSD. In addition, we conducted a systematic meta-analysis to compare the efficacy of different medications in treating PTSD. The effects of methodological study features (including year of publication, duration, number of centres) and sample characteristics (proportion of combat veterans, gender composition) were also tested. The largest body of evidence for short- and long-term efficacy of medication currently exists for SSRIs, with promising initial findings for the selective noradrenergic reuptake inhibitor venlafaxine and the atypical antipsychotic risperidone. Treatment effect was predicted by number of centres and recency of the study, with little evidence that sample characteristics predicted response. Evidence for the effectiveness of benzodiazepines is lacking, despite their continued use in clinical practice. Finally, the α1 antagonist prazosin and the atypical antipsychotics show some efficacy in treatment-resistant PTSD. Adequately powered trials that are designed in accordance with best-practice guidelines are required to provide conclusive evidence of clinically relevant differences in efficacy between agents in treating PTSD, and to help estimate clinical and methodological predictors of treatment response.

Modern medical and surgical management of difficult-to-treat GORD

Approximately 30–40% of patients taking proton pump inhibitors (PPIs) for presumed gastro-oesophageal reflux (GOR) symptoms do not achieve adequate symptom control, especially when no oesophageal mucosal breaks are present at endoscopy and when extra-oesophageal symptoms are concerned. After failure of optimization of medical therapy, a careful work up is mandatory that aims at determining whether symptoms are related to GOR or not. Most patients with refractory symptoms do not have GOR-related symptoms. Some may have symptoms related to weakly acidic reflux and/or oesophageal hypersensitivity. Baclofen is currently the only antireflux compound available as add-on therapy to PPIs, but its poor tolerability limits its use in clinical practice. There is room for pain modulators in patients with hypersensitive oesophagus and functional heartburn. Antireflux surgery is a suitable option in patients responding to medical therapy who want to avoid taking medication or if persisting symptoms can be clearly attributed to poorly controlled GOR.

Epilepsy affects ∼ 1% of the global population, and 33% of patients are nonresponsive to medication and must seek alternative treatment options. Alternative options such as surgery and ablation exist but are not appropriate treatment plans for some patients. Neurostimulation methods such as vagal nerve stimulation, responsive neural stimulation, and deep brain stimulation (DBS) are viable alternatives for medically refractory patients. DBS stimulation has been used in the treatment of Parkinson's disease, dystonia, and pain management. For the treatment of epilepsy, DBS has been found to be an effective treatment plan, with promising results of reduced seizure frequency and intensity. In this review, we discuss DBS surgery and equipment, mechanisms of DBS for epilepsy, and efficacy, technological specifications, and suggestions for future research. We also review a historical summary of experiments involving DBS for epilepsy. Our literature review suggests that further studies are warranted for medically refractory epilepsy using DBS.

The antibiotics, metronidazole and ciprofloxacin, are the first-line treatment for pouchitis. Patients who do not respond to antibiotics or conventional medications represent a major challenge to therapy. In this report, we have described a successful treatment of severe refractory pouchitis with a novel agent, rebamipide, known to promote epithelial cell regeneration and angiogenesis. A 27-year-old male with ileo-anal pouch surgery presented with worsening anal pain, diarrhea, and abdominal pain. The patient was diagnosed to have pouchitis and was given metronidazole together with betamethasone enema (3.95 mg/dose). However, despite this intensive therapy, the patient did not improve. On endoscopy, ulceration and inflammation were seen in the ileal pouch together with contact bleeding and mucous discharge. The patient was treated with rebamipide enema (150 mg/dose) twice a day for 8 wk without additional drug therapy. Two weeks after the rebamipide therapy, stool frequency started to decrease and fecal hemoglobin became negative at the 4th wk. At the end of the therapy, endoscopy revealed that ulcers in the ileal pouch had healed with no obvious inflammation. The effect of rebamipide enema was dramatic and was maintained throughout the 11-mo follow-up. The patient continued to be in remission. No adverse effects were observed during the treatment or the follow-up period. The sustained response seen in this case with severe and refractory pouchitis indicates that agents, which promote epithelial cell growth, angiogenesis and mucosal tissue regeneration, are potential therapeutic agents for the treatment of refractory colorectal lesions.

Onabotulinum toxin A (BT-A) is now one of the authorized prophylaxis treatments for chronic migraine (CM) thanks to previous clinical trials, which usually required a pharmacologic washout as a precondition for demonstrating its efficacy. Aim of our study was to assess the efficacy in daily clinical practice of BT-A injections in refractory CM patients, regardless of medication overuse without any standardized withdrawal protocol and without stopping the ongoing prophylaxis treatment as well. We treated 44 refractory CM patients (37 females and 7 males) trimonthly without any modification in symptomatic, or prophylactic drug therapy. Main efficacy variables included number of headache, or migraine days and episodes, total cumulative headache hours, MIDAS and HIT-6 scores; all items were assessed at baseline and at the 12-, 24-, and 36-week follow-up. All variables showed a statistically significant improvement at week 36. In general, more than 50 % of patients had a good clinical outcome (including all improved patients, either partial or full responder) and that the percentage of drug abuser patients significantly decreased from 75 to 50 %, thanks to a spontaneous reduction of the symptomatic drug intake. Adverse events were uncommon and did not require treatment discontinuation. Onabotulinum toxin A treatment in refractory CM patients with unsatisfactory prophylactic drug treatments and pharmacological abuse is effective in improving clinical outcome and quality of life. This result may be achieved through a flexible pharmacologic approach tailored to each patient's needs; moreover, the patient himself can be often expected to reduce drug consumption spontaneously.

BACKGROUND Surgery is indicated for cerebral cavernous malformations (CCM) that cause medically refractory epilepsy. Real-time magnetic resonance thermography (MRT)-guided stereotactic laser ablation (SLA) is a minimally invasive approach to treating focal brain lesions. SLA of CCM has not previously been described. OBJECTIVE To describe MRT-guided SLA, a novel approach to treating CCM-related epilepsy, with respect to feasibility, safety, imaging, and seizure control in 5 consecutive patients. METHODS Five patients with medically refractory epilepsy undergoing standard presurgical evaluation were found to have corresponding lesions fulfilling imaging characteristics of CCM and were prospectively enrolled. Each underwent stereotactic placement of a saline-cooled cannula containing an optical fiber to deliver 980-nm diode laser energy via twist drill craniostomy. MR anatomic imaging was used to evaluate targeting prior to ablation. MR imaging provided evaluation of targeting and near real-time feedback regarding extent of tissue thermocoagulation. Patients maintained seizure diaries, and remote imaging (6–21 months post-ablation) was obtained in all patients. RESULTS Imaging revealed no evidence of acute hemorrhage following fiber placement within presumed CCM. MRT during treatment and immediate post-procedure imaging confirmed desired extent of ablation. We identified no adverse events or neurological deficits. Four of 5 (80%) patients achieved freedom from disabling seizures after SLA alone (Engel class 1 outcome), with follow-up ranging 12–28 months. Reimaging of all subjects (6–21 months) indicated lesion diminution with surrounding liquefactive necrosis, consistent with the surgical goal of extended lesionotomy. CONCLUSION Minimally invasive MRT-guided SLA of epileptogenic CCM is a potentially safe and effective alternative to open resection. Additional experience and longer follow-up are needed.

One patient had microscopic polyangiitis and HP, which were refractory to cyclophosphamide, azathioprine, rituximab, mycophenolate mofetil (MMF), and mizoribine. Remission was finally achieved with the use of etanercept, but DI occurred 5 years later. The other patient had granulomatosis with polyangiitis, which that was refractory to cyclophosphamide, methotrexate, MMF, and rituximab. DI subsequently developed, but was successfully treated with etanercept. Dura mater hypertrophy was macroscopically observed in the latter case. PMID:28943556

It is estimated that lost productivity related to chronic rhinosinusitis (CRS) costs society in excess of $13 billion per year in the United States. Given this tremendous cost to society, it is important to evaluate the effect of current interventions on improving this productivity loss. To define the change in productivity costs in patients with refractory CRS who select continued medical therapy. Observational cohort study. Thirty-eight patients with a guideline-based diagnosis of CRS whose initial appropriate medical therapy failed were enrolled from 4 tertiary-level rhinology clinics. The study was conducted from December 6, 2010, to April 23, 2013, and data analysis was performed from December 6, 2010, to June 1, 2015. Continued medical therapy for CRS. The human capital approach was applied to quantify productivity costs. Absenteeism, presenteeism, and lost leisure time were quantified to define annual lost productive time, which was measured at enrollment (baseline) and at a minimum of 6 months after treatment. Lost productive time was monetized using the annual daily wage rates obtained from the 2012 US National Census and the 2013 US Department of Labor statistics. Thirty-eight patients with refractory CRS who selected continued medical therapy had a mean (SD) baseline annual productivity cost of $3464 ($4900) per patient. After continued medical therapy for a mean of 12.8 (4.8) months, productivity costs were $2730 ($3720) (before vs after continued medical therapy productivity cost, P = .74). Mean annual absenteeism was reduced from 5 (12) days to 2 (8) days (P = .02). Mean annual presenteeism (17 [27] days reduced to 15 [23] days; P = .93) and mean annual household days lost (7 [7] days reduced to 6 [6] days; P = .51) were maintained at baseline levels. There were no significant differences in productivity outcomes based on endoscopy, the 22-item Sinonasal Outcome Test score, age, or polyp status (all P ≥ .11). Patients with refractory CRS often make treatment decisions based on the degree of quality-of-life and productivity impairment. Outcomes from this study suggest that productivity in patients with refractory CRS who have minor reductions in baseline productivity can remain stable with continued medical therapy. Physicians can use this information to inform appropriate patients with CRS of their expected outcomes from continued medical therapy.

Headaches (cephalgias) are a common reason for patients to seek medical care. There are groups of patients with recurrent headache and craniofacial pain presenting with malignant course of their disease that becomes refractory to pharmacotherapy and other medical management options. Neuromodulation can be a viable treatment modality for at least some of these patients. We review the available evidence related to the use of neuromodulation modalities for the treatment of medically refractory craniofacial pain of different nosology based on the International Classification of Headache Disorders, 2nd edition (ICHD-II) classification. This article also reviews the scientific rationale of neuromodulation application in management of cephalgias. PMID:23682340

Relapsed/refractory acute lymphoblastic leukemia (ALL) has a low remission rate after chemotherapy, a high relapse rate and poor long-term survival even when allogeneic hematopoietic stem cell transplantation (allo-HSCT) is performed. Chimeric antigen receptors redirected T cells (CAR-T cells) can enhance disease remission with a favorable outcome for relapsed/refractory ALL, though some cases quickly relapsed after CAR-T cell treatment. Thus, treatment with CAR-T cells followed by allo-HSCT may be the best way to treat relapsed/refractory ALL. In this review, we first discuss the different types of CAR-T cells. We then discuss the treatment of relapsed/refractory ALL using only CAR-T cells. Finally, we discuss the use of CAR-T cells, followed by allo-HSCT, for the treatment of relapsed/refractory ALL.

Role of Cholestyramine in Refractory Hyperthyroidism: A Case Report and Literature Review

PubMed Central

Alswat, Khaled A.

2015-01-01

Patient: Female, 52 Final Diagnosis: Refractory iodine induced hyperthyroidism Symptoms: Neck swelling • shortness of breath Medication: Cholestyramine Clinical Procedure: Total thyroidectomy Specialty: Endocrinology and Metabolic Objective: Unusual clinical course Background: Hyperthyroidism is a common disease that usually responds to the conventional therapy of anti-thyroidal medications (methimazole or PTU) and beta-blocker. Refractory hyperthyroidism is a rare condition in which hyperthyroidism fails to respond to the above therapy. Cholestyramine has been shown to decrease thyroid hormone level when added to the ongoing anti-thyroidal medications. Case Report: A 52-year-old woman with past medical history of enlarging goiter presented with obstructive symptoms of worsening shortness of breath and snoring. Admission thyroid function test showed mild hyperthyroidism (suppressed TSH, slightly high FT4, and high normal FT3) that worsened after she received a CT scan with contrast and failed to respond to a 3-week course of high-dose dexamethasone, high-dose carbimazole, and up-titrated propranolol. Five days after cholestyramine was added, her FT4 decreased by 30% and normalized after 12 days. The patient underwent total thyroidectomy as definitive treatment for the hyperthyroidism and for the obstructive symptoms. Conclusions: Cholestyramine is an effective additional treatment for hyperthyroidism and may be an effective treatment for refractory iodine-induced hyperthyroidism. The possibility of self-remission (natural course) is less likely given the dramatic and rapid response to cholestyramine. PMID:26207323

Neurofeedback and biofeedback with 37 migraineurs: a clinical outcome study

PubMed Central

2010-01-01

Background Traditional peripheral biofeedback has grade A evidence for effectively treating migraines. Two newer forms of neurobiofeedback, EEG biofeedback and hemoencephalography biofeedback were combined with thermal handwarming biofeedback to treat 37 migraineurs in a clinical outpatient setting. Methods 37 migraine patients underwent an average of 40 neurofeedback sessions combined with thermal biofeedback in an outpatient biofeedback clinic. All patients were on at least one type of medication for migraine; preventive, abortive or rescue. Patients kept daily headache diaries a minimum of two weeks prior to treatment and throughout treatment showing symptom frequency, severity, duration and medications used. Treatments were conducted an average of three times weekly over an average span of 6 months. Headache diaries were examined after treatment and a formal interview was conducted. After an average of 14.5 months following treatment, a formal interview was conducted in order to ascertain duration of treatment effects. Results Of the 37 migraine patients treated, 26 patients or 70% experienced at least a 50% reduction in the frequency of their headaches which was sustained on average 14.5 months after treatments were discontinued. Conclusions All combined neuro and biofeedback interventions were effective in reducing the frequency of migraines with clients using medication resulting in a more favorable outcome (70% experiencing at least a 50% reduction in headaches) than just medications alone (50% experience a 50% reduction) and that the effect size of our study involving three different types of biofeedback for migraine (1.09) was more robust than effect size of combined studies on thermal biofeedback alone for migraine (.5). These non-invasive interventions may show promise for treating treatment-refractory migraine and for preventing the progression from episodic to chronic migraine. PMID:20205867

Oliva, Fabrizio; Alunni, Gianfranco

2002-08-01

Chronic heart failure is an enormous and growing public health problem and is reaching epidemic proportions. Its economic impact is dramatic; two thirds of expenses are for hospitalizations and relatively little is being spent for medications and outpatient visits. Most of the hospitalizations, deaths and costs are incurred by a relatively small minority of patients who may be described as having "complex", "advanced", "refractory" or "end-stage" heart failure; however, in essence they are patients who have severe symptoms and/or recurrent hospitalizations and/or emergency department visits despite maximal oral therapy. Many of the recommendations regarding the management of these patients are based more on experience than on evidence from controlled trials. This, because such patients require an individualized therapy which limits their inclusion in large trials and because support is less easily available when testing specific strategies than when testing specific agents. Improving the treatment of this group of patients by optimizing their medical regimen, aggressive monitoring and providing early intervention to avert heart failure can reduce their morbidity, mortality and costs of care. Refractory heart failure is not a single disease and it is extremely unlikely that all patients should be treated in a similar manner; before selecting the appropriate therapy, the clinician must categorize and profile the patient. The first step should be a re-evaluation of the previous treatment because many patients are treated suboptimally. It is also important to identify reversible or precipitating factors. For patients with advanced heart failure, the initial goal of therapy is to improve symptoms; the next goal is to maintain the improvement and to prevent later deterioration. The appropriate treatment plan will reflect the presence of comorbidities, the patients' history regarding previous responses to therapy, their own expectations with regard to daily life. The most common symptoms causing hospitalizations are those related to congestion; the distinction between the rising filling pressures and low cardiac output puts the focus on the adjustment of further medical therapy. The persistence of congestion confers a worse prognosis and urgency for the consideration of surgical therapies. It has been repeatedly shown that in case of heart failure, fewer hospitalizations and lower costs are necessary after referral to programs that provide multidisciplinary care. This care includes heart failure physician specialists with specifically trained clinical nurses. Other important components of a comprehensive management program for advanced heart failure are patient education, rehabilitation and the availability of adequate social service. We have entered a difficult era marked by a collision course between increasing scientific discoveries and restricted resources; a better care for heart failure, integrating improved medical practice with the necessity of bearing the financial pressures in mind, constitutes a great opportunity for medicine.

Background The anatomical and physiological changes with Roux-en-Y gastric bypass (RYGB) may lead to uncommon but occasionally difficult to treat complications such as hyperinsulinemic hypoglycemia with neuroglycopenia and recalcitrant hypocalcemia associated to hypoparathyroidism. Medical management of these complications is challenging. Laparoscopic reversal of RYGB anatomy with restoration of pyloric function and duodenal continuity is a potential treatment. Objective To present the indications, surgical technique and clinical outcomes of laparoscopic reversal of RYGB. Setting Tertiary Academic Medical Center, United States. Methods Prospective study of consecutive patients offered laparoscopic reversal of RYGB. Results Five patients with remote laparoscopic RYGB underwent laparoscopic reversal of RYGB to normal anatomy (n=2) or modified sleeve gastrectomy (n=3). Indications were medically refractory hyperinsulinemic hypoglycemia with neuroglycopenia (n=3), recalcitrant hypocalcemia with hypoparathyroidism (n=1) and both conditions simultaneously (n=1). Prior to reversal all patients had a gastrostomy tube placed in the excluded stomach to document improvement of symptoms. Laparoscopic reversal was accomplished successfully in all patients. Three post-operative complications occurred; bleeding that required transfusion, gallstone pancreatitis and a superficial trocar site infection. Average length of stay was 3 days. At a mean follow-up of 12 months (range 3 to 22), no additional episodes of neuroglycopenia occurred, average number of hypoglycemic episodes per week decreased from 18.5±12.4 to 1.5±1.9 (p=0.05) and hypocalcemia became responsive to oral replacement therapy in both patients. Conclusions Laparoscopic reversal of RYGB to normal anatomy or modified sleeve gastrectomy is feasible and may be a therapeutic option for selected patients with medically refractory hyperinsulinemic hypoglycemia and/or recalcitrant hypocalcemia associated to hypoparathyroidism.

Purpose: The aim was to report the outcome of Ahmed glaucoma valve (AGV) (New World Medical, Inc., Rancho Cucamonga, CA, USA) implantation as a surgical intervention following an initial failed combined trabeculotomy + trabeculectomy (trab + trab) in refractory primary congenital glaucoma (RPCG). Materials and Methods: Retrospective chart review of 11 eyes of 8 patients who underwent implantation of AGV (model FP8) for RPCG between 2009 and 2011. Prior trab + trab had failed in all the eyes. Success was defined as an intraocular pressure (IOP) >5 and ≤ 18 mmHg during examination under anesthesia with or without medications and without serious complications or additional glaucoma surgery. Results: The mean age at AGV implantation was 15.4 ± 4.9 months. The mean preoperative IOP was 28 ± 5.7 mmHg which reduced to 13.6 ± 3.4 mmHg postoperatively at the last follow-up (P < 0.0001). The number of topical antiglaucoma medications reduced from a mean of 2.6 ± 0.5 to 1.6 ± 0.9 postoperatively (P = 0.009). The definition of qualified success was met in 10 (90%) eyes. One eye developed a shallow anterior chamber with choroidal detachment at 1-week, which resolved spontaneously with medications. None of the eyes developed a hypertensive phase. One eye had a long tube resulting in tube corneal touch that required trimming of the tube. One eye developed tube retraction, which was treated with a tube extender. The mean follow-up was 17.9 ± 9.3 (6.2-35.4) months. Conclusion: Managing RPCG remains a challenge. AGV implant was successful in a significant proportion of cases. PMID:25624676

We present the case of a female patient with arrhythmogenic dysplasia of the right ventricle who evolved to refractory heart failure, ascites, and peripheral edema. As a result, heart transplantation was performed. Subsequently, refractory ascites impaired the patient's respiratory function, resulting in prolonged mechanical ventilation. She was successfully treated with transjugular intrahepatic portosystemic shunt (TIPSS) placement, which allowed satisfactory weaning of ventilatory support.

Management of refractory epilepsy.

Muñana, Karen R

2013-05-01

The term refractory epilepsy is utilized in veterinary medicine to describe a condition in which an animal with epilepsy fails to attain satisfactory seizure control or suffers intolerable side effects despite appropriate therapy with conventional antiepileptic drugs. Refractory epilepsy is an important problem in small animal practice as it occurs in approximately one-third of dogs with epilepsy. Consequently, there is much interest in identifying ways to more effectively treat this population of animals. More than a dozen new antiepileptic drugs have been approved for humans over the last 2 decades, and several of these drugs, including gabapentin, zonisamide, levetiracetam, and pregabalin, have been evaluated for the treatment of refractory seizures in veterinary patients. Nonmedical methods to treat poorly controlled epilepsy are also being explored. The 2 alternative forms of therapy that have shown the most promise in humans with epilepsy are electrical stimulation of the brain and dietary modification, both of which have also been evaluated in dogs. This overview summarizes the available data on pharmacologic as well as nonmedical treatment options for dogs and cats with refractory epilepsy. Although many forms of therapy are currently being utilized in clinical practice, our knowledge of the safety and efficacy of these treatments is limited. Additional randomized controlled trials are needed to better evaluate these novel therapies for refractory epilepsy in dogs and cats. © 2013 Elsevier Inc. All rights reserved.

Reed-Sternberg cells of classical Hodgkin's lymphoma (cHL) are characterized by genetic alterations at the 9p24.1 locus, leading to over-expression of programmed death-ligand 1 and 2. In a phase 1b study, nivolumab, a PD-1-blocking antibody, produced a high response in patients with relapsed or refractory cHL, with an acceptable safety profile. We present a retrospective analysis of 82 patients (median age: 30 years; range: 18-75) with relapsed/refractory HL treated with nivolumab in a named patient program from 24 centers throughout Turkey. The median follow-up was 7 months, and the patients had a median of 5 (2-11) previous lines of therapy. Fifty-seven (70%) and 63 (77%) had been treated by stem-cell transplantation and brentuximab vedotin, respectively. Among 75 patients evaluated after 12 weeks of nivolumab treatment, the objective response rate was 64%, with 16 complete responses (CR; 22%); after 16 weeks, it was 60%, with 16 (26%) patients achieving CR. Twenty patients underwent subsequent transplantation. Among 11 patients receiving allogeneic stem-cell transplantation, 5 had CR at the time of transplantation and are currently alive with ongoing response. At the time of analysis, 41 patients remained on nivolumab treatment. Among the patients who discontinued nivolumab, the main reason was disease progression (n = 19). The safety profile was acceptable, with only four patients requiring cessation of nivolumab due to serious adverse events (autoimmune encephalitis, pulmonary adverse event, and two cases of graft-versus-host disease aggravation). The 6-month overall and progression-free survival rates were 91.2% (95% confidence interval: 0.83-0.96) and 77.3% (0.66-0.85), respectively. Ten patients died during the follow-up; one of these was judged to be treatment-related. Nivolumab represents a novel option for patients with cHL refractory to brentuximab vedotin, and may serve as a bridge to transplantation; however, it may be associated with increased toxicity. © The Author 2017.

Ehen refractory to optimal medical treatment cardiogenic pulmonary edema requires mechanical ventilation as a last therapeutic resource. In recent years an increasing number of authors reported their experience in the management of acute or subacute respiratory failure with non-invasive mechanical ventilation by nasal mask. Encouraged by the first promising results reported in literature we experimented this new therapeutic tool in a first group of seven elderly patients (mean age: 76.57--range: 65-89); they all had been admitted for severe cardiogenic pulmonary edema unresponsive to maximal doses of the conventional drugs available for treating acute decompensated heart failure. The enrolled patients were treated with intermittent ventilation administered by nasal mask at selected values of inspiratory positive airway pressure (IPAP) that were comprised between 10 and 20 cm H2O. At the same time an expiratory positive airway pressure (EPAP) at values comprised between 3 and 8 cm H2O was applied. Ventilation was continued for variable periods of 3-24 hours until acceptable values of PaO2 and PaCO2 were obtained. The ventilation modality was spontaneous, spontaneous-time or timed depending on the patients' level of consciousness at starting time. A good short-term outcome was achieved in all the patients regardless of the ventilation modality applied. The main blood gas alteration was severe hypercapnia with acidosis in three patients, while the other four presented critical hypoxemia unresponsive to simple oxygen supply even if delivered by high-flow Venturi mask. Four of our seven patients were discharged from hospital in satisfactory haemodynamic conditions; the remaining three died during hospitalization from refractory heart failure. In this our preliminary experience the therapeutic approach with nasal positive pressure ventilation (NPPV) and EPAP proved to be very effective to improve the signs and symptoms of acute refractory cardiogenic pulmonary edema as it avoided the need of invasive mechanical ventilation. It was well tolerated by all our patients; besides it was not difficult to use or time-consuming for physician and nurses. On the other hand it didn't modify our patients' medium or long-time prognosis which was strictly related to their preexisting left ventricular pump derangement.

Electroconvulsive therapy (ECT) is considered relatively contraindicated in patients with intracranial space-occupying lesions. A 53-year-old male presented with a 5-year history of medication-refractory major depressive disorder. Brain imaging findings suggested the presence of a ruptured dermoid cyst in the transverse sinus and a calcified meningioma in the temporal lobe sulcal space. There was no evidence of mass effect. Neurofibromatosis was the only other clinical condition present. The patient had no clinical neurological deficits. Since the depression was severe and he was suicidal, ECT was advised. There was a substantial improvement after four bilateral and then eight right unilateral brief-pulse ECTs administered on alternate days, thrice weekly. There were no complications associated with ECT. The treatment gains were maintained with maintenance antidepressant medication at a 1-year follow-up. This is probably the first reported case of the use of ECT in a medication-refractory, severely depressed patient with a ruptured intracranial dermoid cyst and with a calcifying meningioma. The results testify to the safety of ECT even in high-risk patients.

Efficacy of tumor necrosis factor alpha (TNF-α) blockers for treatment of ulcerative colitis that is unresponsive to conventional therapy is unclear due to recent studies yielding conflicting results. To assess the efficacy and safety of anti-TNF-α agents for treatment of ulcerative colitis patients who were intolerant or refractory to conventional medical therapy. Pubmed, Embase, and the Cochrane database were searched. Analysis was performed on randomized controlled trials that assessed anti-TNF-α therapy on ulcerative colitis patients that had previously failed therapy with corticosteroids and/or immunosuppressants. The primary outcome focused on was the frequency of patients that achieved clinical remission. Further trial outcomes of interest included rates of remission without patient use of corticosteroids during the trial, extent of mucosal healing, and the number of cases that resulted in colectomy and serious side effects. Eight trials from seven studies (n = 2122) met the inclusion criteria and were thus included during analysis. TNF-α blockers demonstrated clinical benefit as compared to placebo control as evidenced by an increased frequency of clinical remission (p<0.00001), steroid-free remission (p = 0.01), endoscopic remission (p<0.00001) and a decrease in frequency of colectomy (p = 0.03). No difference was found concerning serious side effects (p = 0.05). Three small trials (n = 57) comparing infliximab to corticosteroid treatment, showed no difference in frequency of clinical remission (p = 0.93), mucosal healing (p = 0.80), and requirement for a colectomy (p = 0.49). One trial compared infliximab to cyclosporine (n = 115), wherein no difference was found in terms of mucosal healing (p = 0.85), colectomy frequency (p = 0.60) and serious side effects (p = 0.23). TNF-α blockers are effective and safe therapies for the induction and maintenance of long-term remission and prevention of treatment by colectomy for patients with refractory ulcerative colitis where conventional treatment was previously ineffective. Furthermore, infliximab and cyclosporine were found to be comparable for treating acute severe steroid-refractory ulcerative colitis.

To report the outcomes associated with the use of rabbit anti-dog thymocyte serum in dogs with haematological immune-mediated diseases. Medical records from 2000 to 2016 of patients diagnosed with immune-mediated haemolytic anaemia, immune-mediated thrombocytopenia, pancytopenia and myelofibrosis were reviewed. All dogs had a severe or refractory disease and received rabbit anti-dog thymocyte serum. Lymphocyte counts were used to monitor the immediate anti-thymocyte effect of therapy; long-term patient outcome was recorded. A total of 10 dogs were included. All dogs except one had a notable decrease in their lymphocyte count after rabbit anti-dog thymocyte serum; four of nine had a decrease to less than 10% of the initial lymphocyte count and one dog reached 10·8%. All dogs were discharged from the hospital following their treatment. The dog with no alteration of lymphocyte count following therapy with rabbit anti-dog thymocyte serum had refractory immune mediated haemolytic anemia and was euthanised within two weeks. All other cases achieved clinical remission with immunosuppressive therapy eventually being tapered (3 of 10) or discontinued (6 of 10). Rabbit anti-dog thymocyte serum therapy might be of interest as an adjunctive therapy in refractory immune-mediated diseases and suppressed lymphocyte counts in most dogs. © 2017 British Small Animal Veterinary Association.

Multiple studies have reported the benefits of vagus nerve stimulation (VNS) on neuropsychological outcomes. The aim of this study was to investigate how VNS affects cognition and psychosocial adjustment in children with refractory epilepsy (RE), and to determine the efficacy of VNS in a Taiwanese population. We conducted a one-group pretest-posttest study on pediatric patients with RE. The study comprised 19 males and 18 females, all aged <18 years. We recorded seizure frequency at 3, 12, and 24 months after VNS device implantation. Intelligence quotients (IQ) were assessed using the Wechsler Intelligence Scale for Children - IV. The Parental Stress Index (PSI) scores were evaluated by a pediatric psychologist. Vagus nerve stimulation device implantation significantly reduced seizure frequency at 3, 12 and 24 months, especially in young children (<12 years). No significant improvement in IQ test performance was observed, though there were significant improvements in the PSI, especially in young children. Vagus nerve stimulation device implantation does not significantly improve cognition function, but it does significantly reduce seizure frequency and stress in parent-child relationships, especially in young children (<12 years). These findings suggest that VNS should be considered as an alternative therapy for patients proven to have seizures that are medically refractory, especially those younger than 12 years of age.

Renal sympathetic denervation (RSD) is emerging as a new therapeutic option for patients with severe hypertension refractory to medical therapy. Patients affected by renovascular or anatomical abnormalities have hitherto been systematically excluded from clinical trials with RSD because of concern about safety and the unknown efficacy of the procedure in this subgroup of patients. We describe the management of a case of RSD in a single-kidney patient with refractory hypertension; the patient had had a previous surgical right nephrectomy for renal cell carcinoma that subsequently required no other oncologic treatment. After multidisciplinary assessment, the patient underwent RSD. The procedure was performed through a 6F femoral access using the Symplicity™ RSD system (Medtronic, Mountain View, CA, USA). Radiofrequency was applied to the renal artery wall in 6 different points under general sedation with midazolam to control back pain caused by the procedure, that was performed without periprocedural complications. The patient was discharged 2 days later after a control of the vascular access site and routine biochemical examinations. The following 9-month follow up showed a significant reduction in blood pressure and stable renal function, without signs of renal damage. Our report confirms the feasibility of RSD in this delicate context, without evident negative effects on kidney function and with a significant reduction in blood pressure. Future studies are needed to fully clarify the value of RSD in single-kidney patients.

Quetiapine for insomnia associated with refractory depression exacerbated by phenelzine.

PubMed

Sokolski, Kenneth N; Brown, Brenda J

2006-03-01

To report the successful treatment of phenelzine-associated insomnia with low-dose quetiapine in a patient with refractory depression. A 42-year-old white man with severe major depression unresponsive to selective serotonin-reuptake inhibitors, bupropion, and tricyclic antidepressants improved following treatment with the monoamine oxidase inhibitor (MAOI) phenelzine. Insomnia, present to a moderate degree prior to antidepressant therapy, worsened markedly following phenelzine treatment and failed to respond to diphenhydramine, temazepam, triazolam, clonazepam, zolpidem, or trazodone given at high therapeutic doses. Sleep disturbance resolved with low-dose (50 mg) adjunctive quetiapine, with no adverse effects. Major depression refractory to standard therapy is a common and serious condition. Some cases respond to MAOIs; however, orthostatic hypotension and insomnia frequently occur. Potentially serious MAOI interactions with psychotropic drugs have raised concerns about combining these agents. In this case, a failure of a number of other medications known to treat MAOI-associated insomnia safely prompted a trial of quetiapine. Despite the possibility that enhanced serotonergic activity might have resulted in serotonin syndrome, no adverse interactions between phenelzine and quetiapine were noted. The use of low-dose, once-daily quetiapine, along with its unique binding properties, may account for its increased safety in combination with phenelzine. This case illustrates that low-dose quetiapine may be an alternative treatment for phenelzine-associated insomnia. Further case reports are needed to establish the safety and effectiveness of combining these agents.

Bupropion inhibits the uptake of dopamine and norepinephrine. Clinical effects in overdose include seizure, status epilepticus, tachycardia, arrhythmias, and cardiogenic shock. We report two cases of severe bupropion toxicity resulting in refractory cardiogenic shock, cardiac arrest, and repeated seizures treated successfully. Patients with cardiovascular failure related to poisoning may particularly benefit from extracorporeal membrane oxygenation (ECMO). These are the first cases of bupropion toxicity treated with veno-arterial EMCO (VA-ECMO) in which bupropion toxicity is supported by confirmatory testing. Both cases demonstrate the effectiveness of VA-ECMO in poisoned patients with severe cardiogenic shock or cardiopulmonary failure.

2016-12-01

The purpose is to report on the safety and efficacy of Ahmed Glaucoma Valve (AGV, New World Medical, Inc., Rancho Cucamonga, CA, USA) implantation for the management of refractory pediatric glaucoma observed during one-year follow up period. A retrospective chart review was conducted on 10 eyes, all younger than 11 years, with pediatric glaucoma that underwent AGV implantation for medicamentously uncontrolled intraocular pressure (IOP) between 2010 and 2014. Outcome measures were control of IOP below 23 mm Hg (with or without antiglaucoma medications) and changes in visual acuity. Complications were recorded. After AGV implantation, IOP values ranged from 18 mm Hg to 23 mm Hg (except for one eye with postoperative hypotonia due to suprachoroid hemorrhage, where the postoperative IOP value was 4 mm Hg). The number of antiglaucoma medications was reduced, i.e. four patients had two medications, one patient had one medication, and the others did not need antiglaucoma medication on the last follow-up visit. One eye had suprachoroid hemorrhage, one eye had long-term persistent uveitic membrane, and two eyes had tube-cornea touch. In conclusion, AGV implantation appears to be a viable option for the management of refractory pediatric glaucoma and shows success in IOP control. However, there was a relatively high complication rate limiting the overall success rate.

New onset refractory status epilepticus (NORSE) is a neurological emergency and difficult to treat condition. We report a case of involuntary movements resulting from thiopentone sodium infusion during the management of refractory status epilepticus. A young woman was admitted with fever and NORSE in the neurology intensive care unit. In addition to supportive measures, she was treated with intravenous lorazepam, phenytoin sodium, sodium valproate, midazolam and thiopentone sodium. While on thiopentone sodium, she developed involuntary twitches involving her upper limbs and face with EEG showing no evidence of ongoing status epilepticus. Because of the temporal relationship with thiopentone infusion, we tapered the dose of thiopentone sodium, which resulted in the disappearance of the movements. The patient recovered well with no recurrence of the seizures during the hospital stay.

Chronic cough is a common complaint and a frequent cause of medical consultation. Its management can be difficult. We present here an overview of the current guidelines for the management of chronic cough. Different steps are detailed, including the initial research of an obvious etiology and alert signs that should lead to further investigation of underlying condition. The diagnosis of the most frequent causes: asthma, non-asthmatic eosinophilic bronchitis, gastroesophageal reflux disease and upper airway cough syndrome should be considered, assessed and treated accordingly. Recent advances have been made in the comprehension of refractory chronic cough pathophysiology as well as its pharmacologic and non-pharmacologic treatment, especially speech pathology therapy.

In Ethiopia, it is not uncommon to encounter refractory glaucoma cases that could be managed with tube-shunt surgery. Tube-shunt implant surgery has been a standard procedure option and widely used for various forms of refractory glaucoma. To described the initial experience and outcome of Ahmed Tube shunt implant for refractory adult Ethiopian glaucoma cases. Retrospective review of consecutive adult patients with refractory glaucoma who underwent Ahmed glaucoma valve implant at the Department of ophthalmology, Menelik II Hospital, Addis Ababa between April 2009 and December 2010. intraocular pressure (IOP), visual acuity, use of supplemental medical therapy and surgical complications. Success was defined as IOP greater than 5 and less than 22 mmHg with at least 30% reduction in IOP from preoperative levels with and without supplemental glaucoma medications, no additional surgeries to lower the IOP and without visual loss of light perception from devastating postoperative complications. Thirteen eyes of 12 patients (10 men, 2 women; mean age 52.4 +/- 15. 7) who underwent glaucoma tube-shunt drainage surgery with Ahmed-tube valve were included in this analysis. The mean preoperative IOP was 31.38 +/- 8.67 mmHg with 2.23 +/- 0.44 antiglaucoma medications. Postoperatively, the mean IOP reduced to 15.52 +/- 8.80 mmHg at 1 week, 14.77 +/- 6.39 mmHg at 1 month, 16.62 +/- 4.48 mmHg at 3 months, and 17.15 +/- 3.87 mmHg at 6 months. The reduction from the preoperative mean IOP at last follow up was 45.3% with 1.08 +/- 0.44 supplemental glaucoma medications. The success rate of IOP controlling according to the definition was 76.9%. The pressure remained below 18 mmHg with and without medication in 9/13 (69.2%) eyes, while three eyes required no medication at all till the last follow-up with sustained IOP < 15 mmHg. At the last follow-up the visual acuity reduced by > or = 2 lines in two eyes while one patient's vision worsened from counting finger of one meter to hand movement. Visual improvement of one and two lines documented in two eyes. Hypotony, Tube-corneal touch, acceleration of cataract, choroidal effusion, flat anterior chamber, visual reduction and tube exposure were the types of complications encountered in 6 eyes, while 3 eyes had more than one complication. The study has shown that tube-shunt implant to be effective in lowering intraocular pressure in refractory glaucoma cases. The few cases reported are indicators of the importance of the procedure in salvaging vision of patients with refractory glaucoma and the need of large scale prospective study in the country.

Recent advances in the management of chronic stable angina II. Anti-ischemic therapy, options for refractory angina, risk factor reduction, and revascularization

PubMed Central

Kones, Richard

2010-01-01

The objectives in treating angina are relief of pain and prevention of disease progression through risk reduction. Mechanisms, indications, clinical forms, doses, and side effects of the traditional antianginal agents – nitrates, β-blockers, and calcium channel blockers – are reviewed. A number of patients have contraindications or remain unrelieved from anginal discomfort with these drugs. Among newer alternatives, ranolazine, recently approved in the United States, indirectly prevents the intracellular calcium overload involved in cardiac ischemia and is a welcome addition to available treatments. None, however, are disease-modifying agents. Two options for refractory angina, enhanced external counterpulsation and spinal cord stimulation (SCS), are presented in detail. They are both well-studied and are effective means of treating at least some patients with this perplexing form of angina. Traditional modifiable risk factors for coronary artery disease (CAD) – smoking, hypertension, dyslipidemia, diabetes, and obesity – account for most of the population-attributable risk. Individual therapy of high-risk patients differs from population-wide efforts to prevent risk factors from appearing or reducing their severity, in order to lower the national burden of disease. Current American College of Cardiology/American Heart Association guidelines to lower risk in patients with chronic angina are reviewed. The Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluation (COURAGE) trial showed that in patients with stable angina, optimal medical therapy alone and percutaneous coronary intervention (PCI) with medical therapy were equal in preventing myocardial infarction and death. The integration of COURAGE results into current practice is discussed. For patients who are unstable, with very high risk, with left main coronary artery lesions, in whom medical therapy fails, and in those with acute coronary syndromes, PCI is indicated. Asymptomatic patients with CAD and those with stable angina may defer intervention without additional risk to see if they will improve on optimum medical therapy. For many patients, coronary artery bypass surgery offers the best opportunity for relieving angina, reducing the need for additional revascularization procedures and improving survival. Optimal medical therapy, percutaneous coronary intervention, and surgery are not competing therapies, but are complementary and form a continuum, each filling an important evidence-based need in modern comprehensive management.

A physiological perspective for utility or futility of alcohol-based hand rub gel against nausea-vomiting: is it P-6 acupoint or transnasal aroma?

PubMed

Gupta, Deepak; Mazumdar, Ashish; Stellini, Michael

2014-09-01

Nausea-vomiting is a common and unpleasant phenomenon with numerous underlying mechanisms and pathways that are not always well elucidated. In clinical practice, refractory nausea-vomiting is encountered in several settings. Antiemetic medications may reduce these symptoms but are not always effective in all patients. In the absence of a well-defined optimal strategy for management of nausea-vomiting, the search for better approaches to treat this distressing symptom continues. One of the alternative treatment approaches is a compounded formulation called ABHR gel that is comprised of multiple antiemetic medications and has been shown to be useful for symptomatic relief in some patients with refractory nausea-vomiting. It has been suggested that alternative mechanisms should be explored to explain the perceived efficacy of ABHR gel, because transdermal absorption leading to nil-to-minimal or subtherapeutic blood concentrations of active ingredients does not explain the role of ABHR gel in the treatment of nausea-vomiting. In the current paper, we discuss possible mechanisms that may explain ABHR transdermal gel's efficacy. Compounded ABHR transdermal gel formulation's efficacy in antagonizing nausea-vomiting that has been recently questioned may be explained by alternative mechanisms mediated through the P-6 acupoint stimulation and facial-nasal, cooling-related counterstimulation. © The Author(s) 2013.

Epstein-Barr virus-positive mucocutaneous ulcer in Crohn's disease. A condition to consider in immunosuppressed IBD patients.

PubMed

Juan, Alba; Lobatón, Triana; Tapia, Gustavo; Mañosa, Míriam; Cabré, Eduard; Domènech, Eugeni

2017-08-01

Epstein-Barr virus-positive mucocutaneous ulcer (EBVMCU) is a little known entity that can affect the oropharyngeal mucosa, the gastrointestinal tract and the skin. The main risk factor for the development of this lesion is immunosuppression. Because its features are similar to other Epstein-Barr virus-associated lymphoproliferative disorders, a differential diagnosis can sometimes prove challenging. Here, we report the case of a man diagnosed with Crohn's disease and treated with azathioprine and infliximab who developed ulceration at the rectum that was refractory to conventional medical treatment. Although the histological characteristics were suggestive of an EBVMCU, lymphoproliferative disease could not be ruled out. The patient did not improve after discontinuation of the treatment, a proctectomy was performed and the diagnosis of this disease was confirmed. Although very few cases of EBVMCU affecting the colon have been reported, its diagnosis should be always considered in refractory cases of inflammatory bowel disease with patients undergoing immunosuppressive treatment.

2015-01-01

Background To evaluate the efficacy and safety of the Ahmed glaucoma valve (AGV) and the risk factors associated with AGV implantation failure in a population of Chinese patients with refractory glaucoma. Method In total, 79 eyes with refractory glaucoma from 79 patients treated in our institution from November 2007 to November 2010 were enrolled in this retrospective study. The demographic data, preoperative and postoperative intraocular pressures (IOPs), best corrected visual acuity (BCVA), number of anti-glaucoma medications used, completed and qualified surgery success rates and postoperative complications were recorded to evaluate the outcomes of AGV implantation. Factors that were associated with implant failure were determined using Cox proportional hazard regression model analysis and multiple linear regression analysis. Principle Findings The average follow-up time was 12.7±5.8 months (mean±SD). We observed a significant reduction in the mean IOP from 39.9±12.6 mm Hg before surgery to 19.3±9.6 mm Hg at the final follow-up. The complete success rate was 59.5%, and the qualified success rate was 83.5%. The number of previous surgeries was negatively correlated with qualified success rate (P<0.05, OR=0.736, 95% CI 0.547-0.99). Patients with previous trabeculectomy were more likely to use multiple anti-glaucoma drugs to control IOP (P<0.01). The primary complication was determined to be a flat anterior chamber (AC). Conclusion AGV implantation was safe and effective for the management of refractory glaucoma. Patients with a greater number of previous surgeries were more likely to experience surgical failure, and patients with previous trabeculectomy were more likely to use multiple anti-glaucoma drugs to control postoperative IOP.

The purpose of this study was to evaluate parenting stress in parents of children with refractory epilepsy before and after their children received vagus nerve stimulation (VNS) implantation. Parents of children with refractory epilepsy completed the Parenting Stress Index (PSI) under a psychologist's assessment before and at least 12 months after their children received VNS implantation. The PSI questionnaire measures parenting stress in two domains; a parent domain with seven subscales, and a child domain with six. Age, gender, epilepsy comorbidity, VNS implantation date, seizure frequency, and anticonvulsant history before and after VNS implantation were obtained from reviews of medical charts. In total, 30 parents completed the first and follow-up PSI questionnaires. Seventeen of their children (56.7%) were boys. The children aged from 1 to 12 years (7.43 ± 3.59 years, mean ± SD). After VNS implantation, the mean total parenting stress scores decreased from 282.1 ± 38.0 to 272.4 ± 42.9. A significant decrease was found on the spouse subscale of the parent domain. For the parents of boys, the mean total parenting stress scores decreased significantly. The mean total parenting stress scores also decreased significantly for parents of epileptic children without autism and who did not taper off the number of different anticonvulsants used after VNS. VNS is an advisable choice to treat refractory epilepsy. Our study showed that 12 months or more after VNS implantation, seizure frequency and parenting stress typically decreased. However, in some special cases the parenting stress may increase, and external help may be required to support these patients and their parents. Copyright © 2017. Published by Elsevier B.V.

Discogenic low back is a distinct clinic entity characterized by pain arising from a damaged disc. The diagnosis is clouded by the controversy surrounding discography. The treatment options are limited, with unsatisfactory results from both conservative treatment and surgery. Multiple interventional therapies have been developed to treat discogenic pain, but most have not yet been validated by high quality studies.The best studied treatment for discogenic pain is the use of heat, which has been labeled as thermal intradiscal procedures (TIPs) by the Centers for Medicare and Medicaid Services (CMS). As the pathology is located in the annulus, we use the term thermal annular procedures (TAPs). The aim of this study is to evaluate and update the efficacy of TAPs to treat chronic refractory discogenic pain. The design of this study is a systematic review. The available literature on TAPs in treating chronic refractory discogenic pain was reviewed. The quality of each article used in this analysis was assessed.The level of evidence was classified on a 5-point scale from strong, based upon multiple randomized controlled trials (RCTs) to weak, based upon consensus, as developed by the US Preventive Services Task Force (USPSTF) and modified by the American Society of Interventional Pain Physicians (ASIPP).Data sources included relevant literature identified through searches of PubMed and EMBASE from 1966 to September 2015 and manual searches of the bibliographies of known primary and review articles.The primary outcome measures were pain relief and functional improvement of at least 40%. Short-term efficacy was defined as improvement for less than 6 months; long-term efficacy was defined as improvement for 6 months or more. For this systematic review, 49 studies were identified. Of these, there were 4 RCTs and no observational studies which met the inclusion criteria. Based upon 2 RCTs showing efficacy, with no negative trials, there is Level I, or strong, evidence of the efficacy of biacuplasty in the treatment of chronic, refractory discogenic pain.Based upon one high-quality RCT showing efficacy and one moderate-quality RCT interpreted as showing no benefit, there is Level III, or moderate, evidence supporting the use of intradiscal electrothermal therapy (IDET) in treating chronic, refractory discogenic pain.The evidence supporting the use of discTRODE is level V, or limited. The evidence is Level I, or strong, that percutaneous biacuplasty is efficacious in the treatment of chronic, refractory discogenic pain. Biacuplasty may be considered as a first-line treatment for chronic, refractory discogenic pain.The evidence is Level III, or moderate, that IDET is efficacious in the treatment of chronic, refractory discogenic pain.The evidence is Level V, or limited, that discTRODE is efficacious in the treatment of chronic, refractory discogenic pain.Key words: Spinal pain, chronic low back pain, intradiscal disorder, IDET, biacuplasty, discTRODE, thermal intradiscal disorders, thermal annular disorders.

Cluster headache is one of the most debilitating pain syndromes. A significant number of patients are refractory to conventional therapies. The Clusterbusters.org medication use survey sought to characterize the effects of both conventional and alternative medications used in cluster headache. Participants were recruited from cluster headache websites and headache clinics. The final analysis included responses from 496 participants. The survey was modeled after previously published surveys and was available online. Most responses were chosen from a list, though others were free-texted. Conventional abortive and preventative medications were identified and their efficacies agreed with those previously published. The indoleamine hallucinogens, psilocybin, lysergic acid diethylamide, and lysergic acid amide, were comparable to or more efficacious than most conventional medications. These agents were also perceived to shorten/abort a cluster period and bring chronic cluster headache into remission more so than conventional medications. Furthermore, infrequent and non-hallucinogenic doses were reported to be efficacious. Findings provide additional evidence that several indoleamine hallucinogens are rated as effective in treating cluster headache. These data reinforce the need for further investigation of the effects of these and related compounds in cluster headache under experimentally controlled settings.

Coccidioidomycosis is an endemic fungal infection caused by the inhalation of the spores of Coccidioides species. Patients with underlying immunosuppressive illness can contract chronic or disseminated disease which requires prolonged systemic therapy. Pulmonary coccidioidomycosis remains as an illusory and abstruse disease, with increased prevalence that poses as a challenge for clinicians in developing an effective strategy for treatment. Here, we report successful treatment of a refractory case of chronic relapsing pulmonary coccidioidomycosis in a 50-year old woman with a thin-walled cavitary lung lesion who was ultimately treated with posaconazole.

Fifteen adults with refractory or recurrent Hodgkin's disease were treated with a combination of: vincristine, prednisolone, etoposide and chlorambucil (OPEC). All had previously received mustine, vinblastine, procarbazine and prednisolone (MVPP) and seven had subsequently been treated with alternative regimens. Responses were achieved in four, but complete remission in only one. Toxicity was considerable and five died of treatment related complications. Only two are alive (one in complete remission) more than three years after therapy. The toxicity of the OPEC regimen outweighed its benefit in this group of poor prognosis patients.

PM01183 is a new compound that blocks active transcription, produces DNA breaks and apoptosis, and affects the inflammatory microenvironment. PM01183 showed strong antitumor activity in preclinical models of cisplatin-resistant epithelial ovarian cancer. Patients with platinum-resistant/refractory ovarian cancer were included in a two-stage, controlled, randomized (in a second stage), multicenter, phase II study. Primary endpoint was overall response rate (ORR) by RECIST and/or GCIG criteria. The exploratory first stage (n = 22) confirmed the activity of PM01183 as a single agent at 7.0 mg flat dose every 3 weeks (q3wk). The second stage (n = 59) was randomized and controlled with topotecan on days 1-5 q3wk or weekly (every 4 weeks, q4wk). ORR was 23% (95% CI, 13%-37%) for 52 PM01183-treated patients. Median duration of response was 4.6 months (95% CI, 2.5-6.9 months), and 23% (95% CI, 0%-51%) of responses lasted 6 months or more. Ten of the 12 confirmed responses were reported for 33 patients with platinum-resistant disease [ORR = 30% (95% CI, 16%-49%)]; for the 29 patients treated with topotecan in the second stage, no responses were found. Median PFS for all PM01183-treated patients was 4.0 months (95% CI, 2.7-5.6 months), and 5.0 months (95% CI, 2.7-6.9 months) for patients with platinum-resistant disease. Grade 3/4 neutropenia in 85% of patients; febrile neutropenia in 21% and fatigue (grade 3 in 35%) were the principal safety findings for PM01183. PM01183 is an active drug in platinum-resistant/refractory ovarian cancer and warrants further development. The highest activity was observed in platinum-resistant disease. Its safety profile indicates the dose should be adjusted to body surface area (mg/m2). EudraCT 2011-002172-16. © The Author 2017.

Treatment of Tourette syndrome.

PubMed

Kurlan, Roger M

2014-01-01

Tourette's syndrome (TS) consists of chronic motor and phonic tics and characteristically begins in childhood. The tics can be disabling and commonly associated behavioral comorbities such as attention deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD), can also cause problems in daily functioning. The underlying etiology and neurobiology of TS remain unknown although genetic factors appear to be important, cortical control of basal ganglia motor function appears to be disturbed and neurochemical abnormalities, particularly involving dopamine neurotransmission, are likely present. The treatment of TS involves appropriate education and support. Tics can be treated with habit reversal cognitive behavioral therapy, medications (most commonly alpha agonists and antipsychotics), local intramuscular injections of botulinum toxin and some severe, refractory cases have responded to deep brain stimulation surgery (DBS). It is important to appropriately diagnose and treat comorbid behavioral disorders that are disrupting function. OCD can be treated with cognitive behavioral therapy, selective serotonin reuptake inhibitors, and atypical antipsychotics. DBS has become a treatment option for patients with disabling OCD despite other therapies. ADHD is treated with appropriate classroom accommodations, behavioral therapy, alpha agonists, atomoxetine or methylphenidate-containing stimulant drugs.

Is Electroconvulsive Therapy a Treatment for Depression Following Traumatic Brain Injury?

PubMed Central

Srienc, Anja; Sarai, Simrat; Xiong, Yee; Lippmann, Steven

2018-01-01

Traumatic brain injury (TBI) can be caused by blunt or penetrating injury to the head. The pathophysiological evolution of TBI involves complex biochemical and genetic changes. Common sequelae of TBI include seizures and psychiatric disorders, particularly depression. In considering pharmacologic interventions for treating post-TBI depression, it is important to remember that TBI patients have a higher risk of seizures; therefore, the benefits of prescribing medications that lower the seizure threshold need to be weighed against the risk of seizures. When post-TBI depression is refractory to pharmacotherapy, electroconvulsive therapy (ECT) could provide an alternative therapeutic strategy. Data remain sparse on using ECT in this seizure-prone population, but three case reports demonstrated good outcomes. Currently, not enough evidence exists to provide clinical recommendations for using ECT for treating post-TBI depression, and more research is needed to generate guidelines on how best to treat depression in TBI patients. However, the preliminary data on using ECT in patients with TBI are promising. If proven safe, ECT could be a powerful tool to treat post-TBI depression. PMID:29707426

The outcome of allogeneic stem cell transplantation depends upon the disease status before transplantation. Patients with refractory disease are at high risk for relapse. To improve the curative potential of the transplant procedure, we treated 3 chemotherapy-refractory CLL patients with alemtuzumab before allogeneic stem cell transplantation. Prior to therapy, all patients suffered from B-symptoms, and had massive adenopathy, splenomegaly, thrombocytopenia, and anemia; two patients had hepatomegaly. Alemtuzumab greatly reduced tumor mass in blood and bone marrow, B-symptoms resolved, and organomegaly improved. Two patients became blood product independent. All patients proceeded to transplantation after conditioning with TBI 2 Gy (n=1) or Treosulfan (n=2) in combination with Fludarabine either from an HLA-matched sibling (n=2) or from an HLA-matched unrelated donor (n=1). All patients engrafted, and are alive and well. Two patients reached complete remission (CR); one patient attained stable partial remission (PR). These heavily pre-treated refractory patients gained substantial clinical benefit from alemtuzumab, and received successful allografts.

There are limited reports of adverse cardiac events with the use of ketamine for RSE and no reports of cardiac arrest in this context. Evaluate the occurrence of cardiac arrhythmias associated with the use of ketamine for RSE. Retrospective chart review of nine patients who underwent ketamine infusion for RSE. Etiology of refractory status epilepticus included autoimmune/infectious process (Zeiler et al., 2014), ischemic stroke (Bleck, 2005) and subarachnoid hemorrhage (Bleck, 2005). Of the nine patients who received ketamine, two had documented cardiac events; one remained clinically stable and the other developed multiple arrhythmias, including recurrent episodes of asystole. Once ketamine was discontinued the latter patient stabilized with the addition of anti arrhythmic therapy. Ketamine is utilized to treat refractory status epilepticus, but should be used with caution in patients with subarachnoid hemorrhage, as there may be an increased risk of life threatening arrhythmias and cardiac arrest.

A case report of outpatient maintenance electroconvulsive therapy (ECT) is presented in a patient with bipolar disorder type I refractory to conventional medication treatment but responsive to ECT. A cost comparison is made showing substantial savings when outpatient maintenance ECT is used in lieu of inpatient hospitalization with ECT. A detailed life chart illustrating multiple medication trials that failed to stabilize the patient accompanies the financial summary. This case highlights the advantages of outpatient maintenance ECT for bipolar depression particularly with regard to safety, efficacy, and significant health care cost reduction.

Pseudophakic cystoid macular edema (PCME) is a common complication following cataract surgery. Acute PCME may resolve spontaneously, but some patients will develop chronic macular edema that affects vision and is difficult to treat. This disease was described more than 50 years ago, and there are multiple options for clinical management. We discuss mechanisms, clinical efficacy, and adverse effects of these treatment modalities. Topical non-steroidal anti-inflammatory agents and corticosteroids are widely used and, when combined, may have a synergistic effect. Intravitreal corticosteroids and anti-vascular endothelial growth factor (anti-VEGF) agents have shown promise when topical medications either fail or have had limited effects. Randomized clinical studies evaluating anti-VEGF agents are needed to fully evaluate benefits and risks. When PCME is either refractory to medical therapy or is associated with significant vitreous involvement, pars plana vitrectomy has been shown to improve outcomes, though it is associated with additional risks.

Gastroesophageal reflux disease (GERD) is a difficult to treat medical condition, where nearly 40% of patients are refractory to standard medical intervention, which typically begins with a proton pump inhibitor (PPI). These PPI nonresponders represent a population of patients, where treatment planning must be individualized; multidisciplinary and psychiatric comorbidities should be considered. This review highlights treatment options that include neuromodulators, lifestyle, and psychological interventions for the PPI nonresponder. Mental health specialists in the field of psychogastroenterology can aid in the management of esophageal hypersensitivity, which can drive the symptom experience of a PPI nonresponder. Considerations for comorbid anxiety and depression in this population require careful assessment and treatment. Physicians are encouraged to create realistic expectations for symptom management and offer multidisciplinary options for treatment early in care. Patients will frequently benefit from working with a GI psychologist and find value in behavioral interventions.

Three dogs were presented to us for evaluation of cardiac problems. Electrocardiographic recordings revealed severe tachyarrhythmia and atrial fibrillation with ventricular tachycardia in 2 of the 3 dogs. The echocardiographic findings of the 3 dogs revealed markedly decreased fractional shortening and a marked increase in E-point septal separation. Based on the results of electrocardiographic and echocardiographic evaluation, the 3 dogs were diagnosed as dilated cardiomyopathy (DCM). The dogs were treated with conventional cardiac medication, but cardiac function did not improve and the clinical signs remained. We subsequently attempted treatment with granulocyte-colony stimulating factor (G-CSF; 10 microg/kg, subcutaneously). The specific purpose of G-CSF therapy for DCM was to improve cardiac function and a significant improvement in cardiac function was confirmed. The three dogs had no treatment side effects. This case report suggests that G-CSF might have therapeutic effects for medically refractory DCM in dogs.

Status epilepticus (SE) describes persistent or recurring seizures without a return to baseline mental status, and is a common neurologic emergency. SE can occur in the context of epilepsy or may be symptomatic of a wide range of underlying etiologies. The clinician’s aim is to rapidly institute care that simultaneously stabilizes the patient medically, identifies and manages any precipitant conditions, and terminates seizures. Seizure management involves “emergent” treatment with benzodiazepines followed by “urgent” therapy with other anti-seizure medications. If seizures persist then refractory SE is diagnosed and management options include additional anti-seizure medications or infusions of midazolam or pentobarbital. This paper reviews the management of pediatric SE and RSE. PMID:25727508

Refractory migraine is a challenging condition with great impact on health related quality of life. Intravenous (IV) ketamine has been previously used to treat various refractory pain conditions. We present a series of patients with refractory migraine treated with intravenous ketamine in the hospital setting. Based on retrospective chart review, we identified six patients with refractory migraine admitted from 2010 through 2014 for treatment with intravenous ketamine. Ketamine was administered using a standard protocol starting with a dose of 0.1 mg/kg/hr and increased by 0.1 mg/kg/hr every 3 to 4 h as tolerated until the target pain score of 3/10 was achieved and maintained for at least 8 h. Visual Analogue Scale (VAS) scores at time of hospital admission were obtained as well as average baseline VAS scores prior to ketamine infusion. A phone interview was conducted for follow-up of migraine response in the 3 to 6 months following ketamine infusion. The study sample had a median age of 36.5 years (range 29-54) and 83% were women. Pre-treatment pain scores ranged from 9 to 10. All patients achieved a target pain level of 3 or less for 8 h; the average ketamine infusion rate at target was 0.34 mg/kg/hour (range 0.12-0.42 mg/kg/hr). One patient reported a transient out-of-body hallucination following an increase in the infusion rate, which resolved after decreasing the rate. There were no other significant side effects. IV ketamine was safely administered in the hospital setting to patients with refractory chronic migraine. Treatment was associated with short term improvement in pain severity in 6 of 6 patients with refractory chronic migraine. Prospective placebo-controlled trials are needed to assess short term and long-term efficacy of IV ketamine in refractory chronic migraine.

Only limited data are available on the role of brentuximab vedotin (SGN-35) in transplant-naive relapsed or refractory patients with Hodgkin lymphoma (HL). We thus retrospectively analyzed 14 patients with primary refractory or relapsed HL who were treated with brentuximab vedotin as single agent in a named patient program, who had not received prior high-dose chemotherapy (HDCT) and autologous stem cell transplant (ASCT) due to refractory disease (n = 9), comorbidity (n = 4) and unknown reasons (n = 1). Brentuximab vedotin resulted in an overall response rate of 71% (10/14) with five complete responses (CRs). Five of those patients with refractory disease and four patients with relevant comorbidity responded. Consolidating ASCT (n = 4) or allogeneic SCT (n = 1) was performed in five patients. Median progression-free survival (PFS) was 9 months and the median overall survival (OS) was not reached. These data indicate the therapeutic efficacy of brentuximab vedotin in chemotherapy-refractory transplant-naive patients with HL.

Women with refractory urgency urinary incontinence are treated with sacral neuromodulation and onabotulinumtoxinA with limited comparative information. To assess whether onabotulinumtoxinA is superior to sacral neuromodulation in controlling refractory episodes of urgency urinary incontinence. Multicenter open-label randomized trial (February 2012-January 2015) at 9 US medical centers involving 381 women with refractory urgency urinary incontinence. Cystoscopic intradetrusor injection of 200 U of onabotulinumtoxinA (n = 192) or sacral neuromodulation (n = 189). Primary outcome, change from baseline mean number of daily urgency urinary incontinence episodes over 6 months, was measured with monthly 3-day diaries. Secondary outcomes included change from baseline in urinary symptom scores in the Overactive Bladder Questionnaire Short Form (SF); range, 0-100, higher scores indicating worse symptoms; Overactive Bladder Satisfaction questionnaire; range, 0-100; includes 5 subscales, higher scores indicating better satisfaction; and adverse events. Of the 364 women (mean [SD] age, 63.0 [11.6] years) in the intention-to-treat population, 190 women in the onabotulinumtoxinA group had a greater reduction in 6-month mean number of episodes of urgency incontinence per day than did the 174 in the sacral neuromodulation group (-3.9 vs -3.3 episodes per day; mean difference, 0.63; 95% CI, 0.13 to 1.14; P = .01). Participants treated with onabotulinumtoxinA showed greater improvement in the Overactive Bladder Questionnaire SF for symptom bother (-46.7 vs -38.6; mean difference, 8.1; 95% CI, 3.0 to 13.3; P = .002); treatment satisfaction (67.7 vs 59.8; mean difference, 7.8; 95% CI, 1.6 to 14.1; P = .01) and treatment endorsement (78.1 vs 67.6; mean difference; 10.4, 95% CI, 4.3 to 16.5; P < .001) than treatment with sacral neuromodulation. There were no differences in convenience (67.6 vs 70.2; mean difference, -2.5; 95% CI, -8.1 to 3.0; P = .36), adverse effects (88.4 vs 85.1; mean difference, 3.3; 95% CI, -1.9 to 8.5; P = .22), and treatment preference (92.% vs 89%; risk difference, -3%; 95% CI, -16% to 10%; P = .49). Urinary tract infections were more frequent in the onabotulinumtoxinA group (35% vs 11%; risk difference, -23%; 95% CI, -33% to -13%; P < .001). The need for self-catheterization was 8% and 2% at 1 and 6 months in the onabotulinumtoxinA group. Neuromodulation device revisions and removals occurred in 3%. Among women with refractory urgency urinary incontinence, treatment with onabotulinumtoxinA compared with sacral neuromodulation resulted in a small daily improvement in episodes that although statistically significant is of uncertain clinical importance. In addition, it resulted in a higher risk of urinary tract infections and need for transient self-catheterizations.

Consensus on the optimal treatment of Clostridium difficile infection (CDI) is rapidly changing. Treatment with metronidazole has been associated with increased clinical failure rates; however, the reasons for this are unclear. The purpose of this study was to assess age-related treatment response rates in hospitalized patients with CDI treated with metronidazole. This was a retrospective, multicenter cohort study of hospitalized patients with CDI. Patients were assessed for refractory CDI, defined as persistent diarrhea after 7 days of metronidazole therapy, and stratified by age and clinical characteristics. A total of 242 individuals, aged 60 ± 18 years (Charlson comorbidity index, 3.8 ± 2.4; Horn's index, 1.7 ± 1.0) were included. One hundred twenty-eight patients (53%) had severe CDI. Seventy patients (29%) had refractory CDI, a percentage that increased from 22% to 28% and to 37% for patients aged less than 50 years, for patients from 50 to 70 years, and for patients aged >70 years, respectively (P = 0.05). In multivariate analysis, Horn's index (odds ratio [OR], 2.04; 95% confidence interval [CI], 1.50 to 2.77; P < 0.001), severe CDI (OR, 2.25; 95% CI, 1.15 to 4.41; P = 0.018), and continued use of antibiotics (OR, 2.65; 95% CI, 1.30 to 5.39; P = 0.0072) were identified as significant predictors of refractory CDI. Age was not identified as an independent risk factor for refractory CDI. Therefore, hospitalized elderly patients with CDI treated with metronidazole had increased refractory CDI rates likely due to increased underlying severity of illness, severity of CDI, and concomitant antibiotic use. These results may help identify patients that may benefit from alternative C. difficile treatments other than metronidazole. PMID:26195522

Purpose A phase I/II study of cixutumumab (IMC-A12) in children with refractory solid tumors was conducted. This study was designed to assess the toxicities, pharmacokinetics, and pharmacodynamics of cixutumumab in children to determine a recommended phase II dose and to assess antitumor activity in Ewing sarcoma (ES). Patients and Methods Pediatric patients with relapsed or refractory solid tumors were treated with cixutumumab as a 1-hour intravenous infusion once per week. Two dose levels—6 and 9 mg/kg—were evaluated using a standard three-plus-three cohort design. Patients with refractory ES were treated in an expanded phase II cohort at each dose level. Results Forty-seven eligible patients with a median age of 15 years (range, 4 to 28 years) were enrolled. Twelve patients were treated in the dose-finding phase. Hematologic and nonhematologic toxicities were generally mild and infrequent. Dose-limiting toxicities included grade 4 thrombocytopenia at 6 mg/kg and grade 3 dehydration at 9 mg/kg. Mean trough concentration (± standard deviation) at 9 mg/kg was 106 ± 57 μg/mL, which exceeded the effective trough concentration of 60 μg/mL observed in xenograft models. Three patients with ES had confirmed partial responses: one of 10 at 6 mg/kg and two of 20 at 9 mg/kg. Serum insulin-like growth factor I (IGF-I) levels consistently increased after one dose of cixutumumab. Tumor IGF-I receptor expression by immunohistochemistry did not correlate with response in patients with ES. Conclusion Cixutumumab is well tolerated in children with refractory solid tumors. The recommended phase II dose is 9 mg/kg. Limited single-agent activity of cixutumumab was seen in ES. PMID:22184397

To investigate the causes of refractory pharyngeal paraesthesia. Besides routine examination of otolaryngology, 600 patients were tested by fiberoptic laryngoscopy, fiberoptic gastroesophagoscopy, nasal sinuses CT, styloid process X-ray as well as neck and thyroid gland B ultrasonography. Then, they were treated according to respective causes. Among 600 cases of refractory pharyngeal paraesthesia, 229 (38.2%) cases were diagnosed as gastroesophagitis, 113 (18.8%) nasal sinusitis, 57 (9.5%) climacteric syndromes, 40 (6.7%) chronic tonsillitis, 22 (3.7%) carcinophobia, 13 (2.2%) subacute thyroiditis or thyrophymas, 9 (1.5%) elongation of styloid process and 117 (19.5%) other causes. All patients were treated according to respective causes and total cure rate was 84.2% after 6 months. There are many causes of pharyngeal paraesthesia. We should pay attention to its relationship with gastroesophagitis and nasal sinusitis etc, especially, gastroesophageal reflux disease.

Ureaplasma Transmitted From Donor Lungs Is Pathogenic After Lung Transplantation.

2017-02-01

Hyperammonemia is a highly fatal syndrome in lung recipients that is usually refractory to medical therapy. We recently reported that infection by a Mollicute, Ureaplasma, is causative for hyperammonemia and can be successfully treated with antimicrobial agents. However, it remains unknown whether the pathogenic strain of Ureaplasma is donor or recipient derived. Here we provide evidence that donor-derived Ureaplasma infection can be pathogenic. As such, we uncover a previously unknown lethal donor-derived opportunistic infection in lung recipients. Given the high mortality associated with hyperammonemia, strategies for routine donor screening or prophylaxis should be further evaluated in prospective studies.

Seizures may present with many different symptom complexes. Seizure semiologies have localization value when contemplating surgical therapies. Epilepsy presenting as a desire to micturate is exceedingly rare, with only a handful of published cases. We present a patient who had initially unexplained childhood urinary urge that progressed into lapses of memory and confusion that was eventually diagnosed as epilepsy in adulthood. Due to refractoriness to medical management, our patient's epileptic focus was localized through both noninvasive and invasive subdural electrode arrays to the nondominant medial temporal lobe and successfully treated with an amygdalohippocampectomy. Only one other case of ictal urinary urgency seizures has been recorded with intracranial electroencephalogram monitoring in the literature.

Purpose of review Pediatric uveitis is relatively uncommon, accounting for only 5–10% of all patients with uveitis. However, owing to high prevalence of complications and devastating outcomes, its lifetime burden can be significant. Recent findings Immunomodulatory therapy has been associated with better outcomes in noninfectious pediatric uveitis. However, effective treatments are limited by medication-related complications, including multiorgan toxicities and systemic side effects. Summary We review the current therapies available to treat pediatric uveitis, discuss novel and future therapies, and provide clinical recommendations utilizing these new agents. The consideration for treatment regimens in noninfectious pediatric uveitis is multifactorial. Understanding past, present, and future technology will aid in treatment of a complex and refractory disease. PMID:23872814

Although idiopathic acute pericarditis is usually a self-limiting disease, in many patients it may recur over a period of months or years. Even if some evidence seems to suggest the possible role of a deranged immune reactivity in the pathogenesis of idiopathic recurrent pericarditis, the etiology of the disease is still unknown. Furthermore, while some trial data confirm the usefulness of colchicine, its medical treatment is not yet clearly established. We here report the clinical history of 2 patients with idiopathic recurrent pericarditis resistant to prednisone, colchicine and other immunosuppressive drugs, who have been successfully treated with high-dose intravenous immunoglobulins.

Objectives: The aims of this study were to determine the etiology, clinical features, and predictors of outcome of new-onset refractory status epilepticus. Methods: Retrospective review of patients with refractory status epilepticus without etiology identified within 48 hours of admission between January 1, 2008, and December 31, 2013, in 13 academic medical centers. The primary outcome measure was poor functional outcome at discharge (defined as a score >3 on the modified Rankin Scale). Results: Of 130 cases, 67 (52%) remained cryptogenic. The most common identified etiologies were autoimmune (19%) and paraneoplastic (18%) encephalitis. Full data were available in 125 cases (62 cryptogenic). Poor outcome occurred in 77 of 125 cases (62%), and 28 (22%) died. Predictors of poor outcome included duration of status epilepticus, use of anesthetics, and medical complications. Among the 63 patients with available follow-up data (median 9 months), functional status improved in 36 (57%); 79% had good or fair outcome at last follow-up, but epilepsy developed in 37% with most survivors (92%) remaining on antiseizure medications. Immune therapies were used less frequently in cryptogenic cases, despite a comparable prevalence of inflammatory CSF changes. Conclusions: Autoimmune encephalitis is the most commonly identified cause of new-onset refractory status epilepticus, but half remain cryptogenic. Outcome at discharge is poor but improves during follow-up. Epilepsy develops in most cases. The role of anesthetics and immune therapies warrants further investigation. PMID:26296517

Severe and Refractory Hypertension in a Young Woman

PubMed Central

Cuadra, René H; White, William B

2016-01-01

Background Refractory hypertension in a young person is an uncommon clinical problem, but one that may be referred to hypertension specialists. Factitious hypertension is fortunately quite rare, but should be considered when evaluating patients who are refractory to numerous classes of antihypertensive therapies and have failed to achieve control despite input from multiple providers. Report of a Case A 19 year old woman was referred to us after failing to achieve blood pressure control by a primary physician and 2 subspecialists in nephrology and hypertension; she also had numerous emergency department visits for symptomatic and severe hypertension. Exhaustive diagnostic testing for secondary causes and witnessed medication dosing in an outpatient setting was unrevealing. Subsequent inpatient admission demonstrated normalization of BPs with small doses of intravenous antihypertensive agents. During the hospitalization, she was observed “pocketing” her oral medications in the buccal folds, and then discarding them in a trash container. Confrontation by psychiatrists and the hypertension specialists led to the admission that she had learned to start and stop beta-blockers and clonidine to induce severe, rebound hypertension. Discussion Factitious and induced hypertension is a rare cause of resistant or refractory hypertension. Nevertheless, hypertension specialists should suspect the diagnosis when there is a history of visits to multiple institutions and physicians, negative secondary workup, absence of overt target organ damage, history of psychiatric illness, and employment in the medical field.

In the current paper, we discussed the outcome of patients with mesial temporal lobe epilepsy (MTLE) and medically-refractory seizures who had surgery at our center in Shiraz, Iran. Patients aged 18 years and older with refractory MTLE and mesial temporal sclerosis operated at Namazee Hospital, Shiraz University of Medical Sciences, Shiraz, Iran from May 2009 through December 2011 were enrolled. Presurgical evaluation included clinical history, neurological examination, 2-hour video-EEG recording, and 1.5-T MRI. All patients were submitted to standard temporal lobectomy at the side determined by MRI and video-EEG. Twenty-two patients (12 women and 10 men) underwent surgery between May 2009 and December 2011. All patients were followed postoperatively for at least 12 months (mean=24.8±7.7 months; minimum=12 months; maximum=36 months). At the last follow-up visit, 18 patients (81.8%) had a good outcome (15 patients [68.2%] had Engel class 1 and three others had Engel class 2). The total cost of presurgical evaluation and epilepsy surgery at our center was less than $500. Resources are limited for the vast majority of medically-refractory patients with epilepsy who live in the developing countries. However, it is feasible to select good surgical candidates for anterior temporal lobectomy relying on the clinical history and examination, MRI and interictal EEG. Broader application of epilepsy surgery should be encouraged in countries with limited financial resources.

Chronic cancer pain is often refractory and difficult to treat. Ketamine is a medication with evidence of efficacy in the treatment of chronic pain. This article presents a synthesis of the data on ketamine for refractory cancer pain in adults and children. There are five randomized, double-blind, controlled trials of ketamine use in cancer pain that demonstrate improvement in pain for some patients. There are six prospective, uncontrolled trials in cancer pain that also demonstrate improvement in pain scores for some patients. There are no randomized, controlled trials in children with cancer pain, although there are a few studies reflecting improved pain control with ketamine for children with cancer pain. Adverse events for adults on ketamine are most commonly somnolence, feelings of insobriety, nausea/vomiting, hallucinations, depersonalization/derealization, and drowsiness. However, when ketamine is combined with benzodiazepines, feelings of insobriety, hallucinations, and depersonalization/derealization are not reported. Children on ketamine have had few reported adverse effects, which include sedation, anorexia, urinary retention, and myoclonic movements. Recommended ketamine infusion dosages are from 0.05 to 0.5 mg/kg/h (intravenous or subcutaneous). Recommended oral dosages of ketamine are 0.2-0.5 mg/kg/dose two to three times daily with a maximum of 50 mg/dose three times daily. Despite limitations in the breadth and depth of data available, there is evidence that ketamine may be a viable option for treatment-refractory cancer pain. Wiley Periodicals, Inc.

An analysis of literature shows that there is still little evidence concerning the efficacy of electroconvulsive therapy (ECT) combined with antipsychotic therapy in a group of treatment-resistant schizophrenia patients. More precisely, its influence on cognitive functions is still equivocal. The aim of this study was to assess the influence of ECT combined with antipsychotic therapy on working memory, attention, and executive functions in a group of treatment-refractory schizophrenia patients. Twenty-seven patients completed the study: 14 men and 13 women, aged 21 to 55 years (mean age, 32.8 years), diagnosed with treatment-resistant schizophrenia. Each patient underwent a course of ECT sessions and was treated with antipsychotic medications. Before the ECT and within 3 days after the last ECT session, the participants were assessed with the following neuropsychological tests: Trail Making Test (TMT) and Wisconsin Cart Sorting Test (WCST). There were no significant differences in the TMT and WCST results after combined ECT and antipsychotic therapy in treatment-refractory schizophrenia patients. According to the results of the neuropsychological tests, there was no decline in attention, executive functions, or working memory. The current study shows no significant difference in attention, working memory, or executive functions after treatment with a combination of electroconvulsive and antipsychotic therapy. This suggests that combined electroconvulsive therapy may not have a negative influence on the neuropsychological functioning of patients with treatment resistant schizophrenia.

We analyzed the treatment responses, toxicities, and survival outcomes of patients with relapsed or refractory multiple myeloma who received daily thalidomide, cyclophosphamide, and dexamethasone (CTD) or daily thalidomide, melphalan, and prednisolone (MTP) at 17 medical centers in Korea. Three-hundred and seventy-six patients were enrolled. The combined chemotherapy of thalidomide, corticosteroid, and an alkylating agent (TAS) was second-line chemotherapy in 142 (37.8%) patients, and third-line chemotherapy in 135 (35.9%) patients. The response rate overall was 69.4%. Patients who were not treated with bortezomib and lenalidomide before TAS showed a higher response rate compared to those who were exposed to these agents. The estimated median progression-free survival and overall survival times were 10.4 months and 28.0 months, respectively. The adverse events during TAS were generally tolerable, but 39 (10.4%) patients experienced severe infectious complications. There were no differences in terms of efficacy between CTD and MTP, but infectious complications were more common in CTD group. TAS is an effective treatment regimen which induces a high response rate in relapsed or refractory multiple myeloma patients. Due to the high incidence of grade 3 or 4 infection, proper management of infection is necessary during the TAS treatment, especially the CTD. © 2016 The Authors.

Patient: Male, 25 Final Diagnosis: Ulcerative colitis and chronic fatigue syndrome Symptoms: Colitis • profound fatigue • multi-joint pain • cognitive impairment • corneal keratitis Medication: — Clinical Procedure: VIP replacement therapy Specialty: Family Medicine Objective: Unusual clinical course Background: Patients with multisymptom chronic conditions, such as refractory ulcerative colitis (RUC) and chronic fatigue syndrome (CFS), present diagnostic and management challenges for clinicians, as well as the opportunity to recognize and treat emerging disease entities. In the current case we report reversal of co-existing RUC and CFS symptoms arising from biotoxin exposures in a genetically susceptible individual. Case Report: A 25-year-old previously healthy male with new-onset refractory ulcerative colitis (RUC) and chronic fatigue syndrome (CFS) tested negative for autoimmune disease biomarkers. However, urine mycotoxin panel testing was positive for trichothecene group and air filter testing from the patient’s water-damaged rental house identified the toxic mold Stachybotrys chartarum. HLA-DR/DQ testing revealed a multisusceptible haplotype for development of chronic inflammation, and serum chronic inflammatory response syndrome (CIRS) biomarker testing was positive for highly elevated TGF-beta and a clinically undetectable level of vasoactive intestinal peptide (VIP). Following elimination of biotoxin exposures, VIP replacement therapy, dental extractions, and implementation of a mind body intervention-relaxation response (MBI-RR) program, the patient’s symptoms resolved. He is off medications, back to work, and resuming normal exercise. Conclusions: This constellation of RUC and CFS symptoms in an HLA-DR/DQ genetically susceptible individual with biotoxin exposures is consistent with the recently described CIRS disease pathophysiology. Chronic immune disturbance (turbatio immuno) can be identified with clinically available CIRS biomarkers and may represent a treatable underlying disease etiology in a subset of genetically susceptible patients with RUC, CFS, and other immune disorders.

Vasoplegia syndrome, characterized by hypotension refractory to fluid resuscitation or high-dose vasopressors, low systemic vascular resistance, and normal-to-increased cardiac index, is associated with increased morbidity and mortality after cardiothoracic surgery. Methylene blue inhibits inducible nitric oxide synthase and guanylyl cyclase, and has been used to treat vasoplegia during cardiopulmonary bypass. However, because methylene blue is associated with increased pulmonary vascular resistance, its use in patients undergoing lung transplantion has been limited. Herein, we report the use of methylene blue to treat refractory vasoplegia during cardiopulmonary bypass in a patient undergoing double-lung transplantation.

The role of antiviral therapy in patients with ulcerative colitis (UC) with cytomegalovirus (CMV) remains unclear. We therefore performed a systematic review and meta-analysis to assess the association between antiviral therapy and the risk of colectomy. Multiple electronic databases were searched systematically through July 2014 for studies reporting the risk of colectomy in patients with UC with CMV stratified by treatment with antiviral agents. Colectomy rates were assessed for the overall cohort and stratified by corticosteroid (CS) refractoriness. We estimated summary odds ratios and 95% confidence intervals, using random-effects model, and used Grading of Recommendations Assessment, Development, and Evaluation criteria to appraise the quality of evidence. Fifteen observational studies (333 patients with UC with CMV, 43.2% treated with antiviral agents) were identified, of which 8 stratified patients according to CS-refractory disease (55.4% treated with antiviral agents). Antiviral therapy resulted in a significantly lower risk of colectomy in patients with CS-refractory disease (odds ratio, 0.20; 95% confidence interval, 0.08-0.49; I = 0%) but not in the overall population of patients with UC (odds ratio, 0.92; 95% confidence interval, 0.31-2.76; I = 65). The quality evidence was low. The results were stable when restricting the analysis to patients with a tissue diagnosis of CMV and studies that defined CS-refractory disease as a failure to respond to intravenous CS. Antiviral therapy may benefit a subgroup of patients with UC who are refractory to CS. Further prospective trials are required to confirm these findings.

Can anesthetic treatment worsen outcome in status epilepticus?

PubMed

Sutter, Raoul; Kaplan, Peter W

2015-08-01

Status epilepticus refractory to first-line and second-line antiepileptic treatments challenges neurologists and intensivists as mortality increases with treatment refractoriness and seizure duration. International guidelines advocate anesthetic drugs, such as continuously administered high-dose midazolam, propofol, and barbiturates, for the induction of therapeutic coma in patients with treatment-refractory status epilepticus. The seizure-suppressing effect of anesthetic drugs is believed to be so strong that some experts recommend using them after benzodiazepines have failed. Although the rationale for the use of anesthetic drugs in patients with treatment-refractory status epilepticus seems clear, the recommendation of their use in treating status epilepticus is based on expert opinions rather than on strong evidence. Randomized trials in this context are lacking, and recent studies provide disturbing results, as the administration of anesthetics was associated with poor outcome independent of possible confounders. This calls for caution in the straightforward use of anesthetics in treating status epilepticus. However, there are still more questions than answers, and current evidence for the adverse effects of anesthetic drugs in patients with status epilepticus remains too limited to advocate a change of treatment algorithms. In this overview, the rationale and the conflicting clinical implications of anesthetic drugs in patients with treatment-refractory status epilepticus are discussed, and remaining questions are elaborated.

Refractory or relapsed B lymphoblastic leukemia (B-ALL) patients have a dismal outcome with current therapy. We treated 42 primary refractory/hematological relapsed (R/R) and 9 refractory minimal residual disease by flow cytometry (FCM-MRD + ) B-ALL patients with optimized second generation CD19-directed CAR-T cells. The CAR-T-cell infusion dosages were initially ranged from 0.05 to 14 × 10 5 /kg and were eventually settled at 1 × 10 5 /kg for the most recent 20 cases. 36/40 (90%) evaluated R/R patients achieved complete remission (CR) or CR with incomplete count recovery (CRi), and 9/9 (100%) FCM-MRD + patients achieved MRD - . All of the most recent 20 patients achieved CR/CRi. Most cases only experienced mild to moderate CRS. 8/51 cases had seizures that were relieved by early intervention. Twenty three of twenty seven CR/CRi patients bridged to allogeneic hematopoietic stem cell transplantation (allo-HCT) remained in MRD - with a median follow-up time of 206 (45-427) days, whereas 9 of 18 CR/CRi patients without allo-HCT relapsed. Our results indicate that a low CAR-T-cell dosage of 1 × 10 5 /kg, is effective and safe for treating refractory or relapsed B-ALL, and subsequent allo-HCT could further reduce the relapse rate.

For some career military aviators, their ability to continue on flight status is limited by the pressure and pain of aerosinusitis, which is present only while in the flying environment. Failure to treat their disease process can mean the end of their flying careers and the loss of valuable assets trained with taxpayer dollars. Because some medications commonly used in treatment of sinus diseases are not allowed in aviation, this presents a unique problem for their medical management. Surgical treatment must be aimed at treating to symptom relief and not solely disease mitigation. One alternative is operating "beyond the scope of disease" present during a one-atmosphere clinic visit. A case series of nine career aviators with aerosinusitis treated at one academic military Otolaryngology department in a tertiary care facility. Results from a treatment algorithm that balances symptomatology and staged surgical intervention are reviewed. The primary endpoint was return to flight duty. For patients treated according to this algorithm, the mean time to return to flight duty was 3.8 mo, requiring an average of 1.2 surgeries. To date, 100% of career aviators have returned to flight duty using this method. Refractory aerosinusitis represents a potentially career-ending medical condition for the aviator and lost training costs to the taxpayers. Using the treatment algorithm presented, 100% of aviators were able to return to flight duty; a savings of millions of dollars for taxpayers. Future work will focus on modifications to the surgical techniques to reduce the extent of surgery while maintaining satisfactory results. Additional study should be undertaken to assess generalizability of these results in the broader aviation community. © Association of Military Surgeons of the United States 2018. All rights reserved.

Refractory shoulder tendinitis or partial thickness rotator cuff tears (PTRCTs) are common findings in overhead athletes. Previous studies have examined the effectiveness of extracorporeal shockwave therapy (ESWT) for shoulder tendinitis. In the current study, we recruited 36 shoulders and performed a comparison between the professional athletes (13 shoulders, athletic group; AG) and the non-athletic population (23 shoulders, non-athletic group, NAG) with PTRCTs or shoulder tendinitis of the shoulder after ESWT. Patients with symptomatic tendinitis of the shoulder with or without a partial tear of the rotator cuff tendon and failed oral medication and physical therapy for more than 3 months were treated with electrohydraulic mode of ESWT. All patients that met the inclusion criteria were categorized into two groups according to their pre-treatment activity level. We found that NAG exhibited significant aging and degenerative change around the glenohumeral joint and subacromial space. After ESWT treatment, the patients in AG were with 53.8% high satisfaction rating and patients in NAG were 52.1% by one-year followed up. The results showed ESWT was equally effective treatment in both AG and NAG. In light of its efficacy and less-invasive nature, we suggest ESWT can be used to treat athletes with refractory tendinitis or PTRCTs before proceeding to arthroscopic intervention.

Objective The objective of this study was to find out the clinical variables correlated with repeated intra-arterial (IA) nimodipine infusions in patients with medically refractory cerebral vasospasm (CV) following subarachnoid hemorrhage (SAH). Materials and Methods During the 36 months between January 2011 and December 2013, 275 patients were treated at our institute for SAH due to a ruptured intracranial aneurysm. Of the 275 patients, 26 patients (9.5%) met the inclusion criteria. For each patient, a retrospective review of their medical records was conducted. Results Eleven patients underwent a single IA nimodipine infusion and 15 patients underwent more than two IA nimodipine infusions. Multiple IA nimodipine infusion patients had poor improvement (2 of 15 patients, 13.3%) in Glasgow coma scale (GCS) scores after the first IA nimodipine infusion compared to patients of single IA nimodipine infusion (6 of 11 patients, 54.6%) (p = 0.038). The mean middle cerebral artery (MCA) Lindegaard ratio of multiple IA nimodipine infusion patients was 4.3 ± 1.1 after the first IA nimodipine infusion (p = 0.039). In multiple IA nimodipine infusion patients, CV occurred more often bilaterally (p = 0.035) and distally (p = 0.001). More vessel segments were affected in multiple IA nimodipine infusion patients (3.1 ± 1.0) (p < 0.001). Conclusion The following factors correlated with multiple IA nimodipine infusions: 1) no improvement in GCS after the IA nimodipine infusion; 2) no decrease of MCA velocity on transcranial doppler over 50 cm/s or Lindegaard ratio over 4.3 after the IA nimodipine infusion; 3) distal, bilateral, or diffuse involvement of CV.

Diabetic and Nondiabetic Gastroparesis.

PubMed

McCallum; Brown

1998-12-01

Nutritional support is essential in treating patients with gastroparesis. Initially, dietary changes should be instituted to reduce extra fat and bulk, and patients should be encouraged to eat frequent small meals with liquid supplementation. Enteral feeding should be introduced in the event of weight loss or persistent vomiting. Medical therapy is usually necessary early in treatment. Cisapride is the initial agent of choice and may be combined with an antiemetic agent, such as promethazine or chlorpromazine or, if side effects occur, ondansetron and granesitron. If cisapride is ineffective or contraindicated, metoclopramide is a reasonable option, though limited by side effects. Erythromycin is useful in the acute treatment of postoperative ileus and hospitalized gastroparetic patients, but its role is limited based on concerns about poor long-term effectiveness and antimicrobial resistance. Once domperidone becomes available in the United States, it will be useful for its promotility and antiemetic qualities. Combination therapy should be considered if monotherapy with cisapride or metoclopramide alone is ineffective. While not yet well studied, combination therapy has the potential to offer dramatic benefit for patients with refractory gastroparesis. Metoclopramide may be added to cisapride for patients with breakthrough symptoms or refractory chronic symptoms. Other combinations include metoclopramide with erythromycin, domperidone with cisapride, and domperidone with erythromycin. In the future, gastric pacing may become an effective option for patients not responding to medical therapy. Total gastrectomy should be performed only for end-stage gastroparesis when all other therapy has failed. Both procedures should be reserved for centers that specialize in severe gastric motility disorders.

While the pharmacological armamentarium for chronic constipation has expanded over the past few years, a substantial proportion of constipated patients do not respond to these medications. This review summarizes the pharmacological and behavioral options for managing constipation and details the management of refractory constipation. Refractory constipation is defined as an inadequate improvement in constipation symptoms evaluated with an objective scale despite adequate therapy (ie, pharmacological and/or behavioral) that is based on the underlying pathophysiology of constipation. Minimally invasive (ie, rectal irrigation and percutaneous endoscopic colostomy) and surgical therapies are used to manage refractory constipation. This review appraises these options, and in particular, percutaneous endoscopic colostomy, which as detailed by an article in this issue, is a less invasive option for managing refractory constipation than surgery. While these options benefit some patients, the evidence of the risk: benefit profile for these therapies is limited. © 2018 John Wiley & Sons Ltd.

Updates in Refractory Status Epilepticus

Mahulikar, Advait; Suchdev, Kushak; Shah, Aashit

2018-01-01

Refractory status epilepticus is defined as persistent seizures despite appropriate use of two intravenous medications, one of which is a benzodiazepine. It can be seen in up to 40% of cases of status epilepticus with an acute symptomatic etiology as the most likely cause. New-onset refractory status epilepticus (NORSE) is a recently coined term for refractory status epilepticus where no apparent cause is found after initial testing. A large proportion of NORSE cases are eventually found to have an autoimmune etiology needing immunomodulatory treatment. Management of refractory status epilepticus involves treatment of an underlying etiology in addition to intravenous anesthetics and antiepileptic drugs. Alternative treatment options including diet therapies, electroconvulsive therapy, and surgical resection in case of a focal lesion should be considered. Short-term and long-term outcomes tend to be poor with significant morbidity and mortality with only one-third of patients reaching baseline neurological status. PMID:29854452

Adoptive immunotherapy utilizing anti-CD19 chimeric antigen receptor T-cells for B-cell malignancies.

PubMed

Oh, Iekuni; Oh, Yukiko; Ohmine, Ken

2016-01-01

Genetically modified T-cells with forced expression of anti-CD19 chimeric antigen receptor (CD19 CAR) have demonstrated promising clinical results for relapsed and refractory B cell malignancies in early clinical trial settings. The first beneficial tumor regressions were identified among approximately half of CLL patients in 2011. Similarly, CD19 CAR T-cells achieved remissions in about 80% of aggressive B-cell lymphomas in 2012. Furthermore, in 2013 this cellular therapy showed an extremely high rate of efficacy against refractory CD19 positive acute lymphoid leukemia, which had been regarded as the most difficult to treat hematologic disease. Recently, despite the absence of CD19 expression by neoplastic plasma cells, patients with refractory multiple myeloma achieved stringent complete remission after this therapy coupled with high dose chemotherapy and autologous stem cell transplantation. However, there are significant toxicities. Cytokine releasing syndrome and neurotoxicity are recognized as life-threatening adverse events. Although phase I/II clinical trials have just started in Japan, given the exciting results obtained to date, this cellular therapy is expected to be a novel breakthrough immunotherapy for treating refractory B-cell malignancies.

What is the full range of medical and surgical treatments available for patients with Eustachian tube dysfunction?

To present the current medical and surgical treatment options for Eustachian tube dysfunction. Balloon dilation or microdebrider Eustachian tuboplasty are feasible treatment options for patients with refractory dilatory dysfunction as an alternative to tympanostomy tube placement. There is increasing evidence that repair of patulous Eustachian tubes by the insertion of a shim or fat graft reconstruction within the lumen of the Eustachian tube orifice may be effective. In patients with Eustachian tube dysfunction that is refractory to medical management, newer surgical techniques may provide symptomatic relief with a reasonable duration. Continued basic science research into the cause of dysfunction, the mechanisms of benefit from intervention and long-term clinical outcomes are necessary.

Treatment options for patients with platinum refractory metastatic germ cell tumours (GCT) relapsing after high-dose chemotherapy and autologous stem cell transplantation are limited and survival is poor. Antibodies directed against programmed cell death protein-1 (PD-1) and programmed cell death ligand-1 (PD-L1) are currently assessed within clinical trials. We present updated data on our experience with checkpoint inhibitors as a compassionate use off-label treatment attempt for highly-pretreated patients with GCT and provide an overview of the current literature on PD-L1 expression in this rare tumour entity. We analysed all patients with platinum refractory GCT treated with checkpoint inhibitors at our institutions between 2015 and 2017. Data were retrieved retrospectively from the patient charts. Seven patients were treated with nivolumab or pembrolizumab. Four patients received single-dose treatment and died shortly afterwards due to tumour progression; the remaining three patients received treatment for at least 6 months. No significant treatment toxicity was observed. Long-term tumour response was achieved in two of the three patients, both of them highly positive for PD-L1 staining. We consider checkpoint inhibition to be efficient in carefully selected patients with platinum refractory GCT. However, predictive markers associated with tumour response are not yet known and larger prospective clinical trials are warranted. Copyright © 2017 Elsevier Ltd. All rights reserved.

Acquired idiopathic thrombotic thrombocytopenic purpura (I-TTP) is a life-threatening microangiopathic disorder usually treated with therapeutic plasma exchange (TPE). The current study assessed the role of rituximab in the treatment of complicated I-TTP. The sequence of TTP events was compared in a group of I-TTP patients treated with TPE and a cohort of refractory or relapsed patients who also received rituximab. This retrospective evaluation included 45 I-TTP patients, treated between January 2000 and October 2013, who underwent at least 3 TPE procedures and were followed up until December 2013 or death. Thirty-one patients with an uncomplicated course received TPE only. Fourteen patients had a complicated course due to either a primary refractory/exacerbated disease (n = 5) or relapse (n = 9) and received rituximab together with TPE. The median number of TPE procedures performed in the first TTP episode in the uncomplicated cohort and groups with primary refractory or relapsed TTP was 11, 27 and 45, respectively. The relapse rates per follow-up year in the uncomplicated I-TTP, primary refractory and relapsed I-TTP groups were 0.18, 0.2 and 0.6 episodes, respectively. After rituximab therapy this rate dropped to 0.2 per year in the relapsed subgroup. In conclusion, about a quarter of patients with I-TTP had a complicated course and experienced a major benefit from rituximab in terms of effectiveness and safety. © 2015 S. Karger AG, Basel.

Objective To evaluate the long-term cost-effectiveness of endoscopic sinus surgery (ESS) compared to continued medical therapy for patients with refractory chronic rhinosinusitis (CRS). Study Design Cohort-style Markov decision tree economic evaluation Methods The economic perspective was the US third party payer with a 30 year time horizon. The two comparative treatment strategies were: 1) ESS followed by appropriate postoperative medical therapy and 2) continued medical therapy alone. Primary outcome was the incremental cost per quality adjusted life year (QALY). Costs were discounted at a rate of 3.5% in the reference case. Multiple sensitivity analyses were performed including differing time-horizons, discounting scenarios, and a probabilistic sensitivity analysis (PSA). Results The reference case demonstrated that the ESS strategy cost a total of $48,838.38 and produced a total of 20.50 QALYs. The medical therapy alone strategy cost a total of $28,948.98 and produced a total of 17.13 QALYs. The incremental cost effectiveness ratio (ICER) for ESS versus medical therapy alone is $5,901.90 per QALY. The cost-effectiveness acceptability curve from the PSA demonstrated that there is 74% certainty that the ESS strategy is the most cost-effective decision for any willingness to pay threshold greater then $25,000. The time horizon analysis suggests that ESS becomes the cost-effective intervention within the 3rd year after surgery. Conclusion Results from this study suggest that employing an ESS treatment strategy is the most cost-effective intervention compared to continued medical therapy alone for the long-term management of patients with refractory CRS.

Medical records of 22 dogs treated with carboplatin (n = 8) or carboplatin and cytarabine (n = 14) chemotherapy for relapsed or refractory lymphoma between 2000 and 2013 were retrospectively reviewed. The clinical response rate was 18.2% (4/22). Median time to progression was 18 days (56 for responders; 12 for non-responders, P = 0.0006). Median overall survival time was 28 days (109 for responders; 21 for non-responders, P = 0.0007). Thrombocytopenia and neutropenia occurred in 84.2% (16/19) and 52.6% (10/19), respectively. Grade IV thrombocytopenia and neutropenia occurred in 56.3% (9/16) and 60.0% (6/10), respectively. Dogs that received both drugs were more likely to become neutropenic (P = 0.022) or thrombocytopenic (P = 0.001) than dogs receiving carboplatin alone. All responders received both drugs giving a 28.6% (4/14) response rate for the combination. Although some dogs responded to the combination, toxicity was high and the responses were not durable. With adequate supportive care, this protocol may be an acceptable rescue option for some dogs. © 2015 John Wiley & Sons Ltd.

Prostatic haematuria is among the most common genitourinary complaints of emergency room visits, distressing and troublesome to men and a challenging clinical problem to the treating physician. The most common aetiologies of prostatic haematuria include benign prostatic hyperplasia and prostate cancer. Prostatic haematuria usually resolves with conservative and medical methods; failure of these interventions results in refractory haematuria of prostatic origin (RHPO), a potentially life-threatening scenario. Several different treatments have been described, with varying degrees of success. Patients with RHPO are often elderly and unfit for radical surgery. Prostate artery embolization (PAE) has evolved as a safe and effective technique in the management of RHPO. Use of a superselective approach optimizes clinical success while minimizing complications. This minimally invasive approach improves patients with haemodynamic instability, serves as a bridge to elective surgery, and is a highly effective treatment for RHPO. It may obviate the need for more invasive and morbid surgical therapies. The aim of the present review was to describe the current management of RHPO and the technique of PAE and to review its efficacy and associated morbidity. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

Systemic lupus erythematosus presenting as Stevens-Johnson syndrome/toxic epidermal necrolysis.

Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN)-like lesions in acute cutaneous lupus erythematosus [LE]) are an unusual manifestation of systemic LE. We describe a patient with widespread vesiculobullous lesions diagnosed as SJS/TEN-like acute cutaneous LE as the initial presentation of systemic LE. Stevens-Johnson syndrome/TEN-like LE may be differentiated from other vesiculobullous lesions by factors including a history of recent LE exacerbation, photodistribution of lesions, lack of a precipitating infection or medication exposure, minimal mucosal involvement, a prolonged course, response steroid treatment, and histologic and immunofluorescence findings. It is paramount to identify SJS/TEN-like LE as this condition requires early and aggressive intervention. The optimal treatment approach for SJS/TEN-like LE is unclear, and although some case reports have shown glucocorticoids to be useful, there are also reports of cases in which additional measures, such as intravenous immunoglobulin and plasmapheresis, were required to achieve a response. Our patient's condition was refractory to high-dose corticosteroids and intravenous immunoglobulin but was successfully treated using plasma exchange. As such, this treatment may hold potential for improving the care of other patients with refractory SJS/TEN-like LE.

Hemimegalencephaly (HME) is a rare congenital brain malformation of unknown etiology. Patients with HME can present with an early onset epileptic syndrome which is often refractory to medical treatment and associated to impaired neurological development. Functional hemispherectomy (FH) has proven to be a valuable treatment alternative in patients with refractory epilepsy in this setting. Very few children operated under the age of 6 months and bearing HME and catastrophic epilepsy (CE) have been described in the literature. This study reports on 2 kids younger than 6 months with HME and CE submitted to FH with good clinical outcome.

Decompressive craniectomy in pediatric central nervous infections with refractory intracranial hypertension is less commonly practiced. We describe improved outcome of decompressive craniectomy in a 7-year-old boy with severe herpes simplex encephalitis and medically refractory intracranial hypertension, along with a brief review of the literature. Timely recognition of refractory intracranial hypertension and surgical decompression in children with herpes simplex encephalitis can be life-saving. Additionally, strokelike atypical presentations are being increasingly recognized in children with herpes simplex encephalitis and should not take one away from the underlying herpes simplex encephalitis. © The Author(s) 2014.

Epilepsy surgery in context of neurocysticercosis

PubMed Central

Singh, Gagandeep; Chowdhary, Ashwani Kumar

2014-01-01

The association between neurocysticercosis (NCC) and epilepsy is well known and NCC is an important risk factor for epileptic seizures in many Taenia solium-endemic regions of the world. However, while the relationship between NCC and epilepsy is well known, the association between NCC and medically refractory (or surgically remediable epilepsy) has received little attention in the past. Our experience and review of the sparse literature available suggests that NCC is causally related to surgically remediable epilepsy albeit uncommonly so and that association derives its underpinnings from several different scenarios: (1) Medically refractory lesional epilepsy, in which seizures arise from the vicinity of the calcified neurocysticercus lesion (CNL), (2) Medically refractory epilepsy with dual pathology type of relationship between the hippocampal sclerosis (HS) and CNL in which both have been unequivocally demonstrated to give rise to independent seizures and (3) Mesial temporal lobe epilepsy due to HS with a distantly-located CNL, which is in itself not epileptogenic. A major point of controversy revolves around whether or not there exists a causal association between the CNL and HS. We believe that an association exists between NCC and HS and the most important factor influencing this association is the location of the CNL. Furthermore, NCC is a risk factor for medically-refractory epilepsy and that this might account for a considerable proportion of the intractable epilepsy population in endemic regions; the association has been largely ignored owing to the lack of availability of presurgical work-up facilities in these regions. Finally, from a clinical standpoint of presurgical evaluation, patients with CNL and HS should be evaluated on a case by case basis owing to disparate settings underlying the association.

The impact of family factors on IQ in pediatric medically refractory epilepsy.

2017-02-01

To evaluate whether family factors were associated with intellectual functioning among children with medically refractory epilepsy, and whether family factors moderate the relationship between patient/epilepsy-related variables and intellectual functioning. Children aged 4 to 18 years with medically refractory epilepsy who were evaluated for surgical candidacy were recruited. The authors assessed the association of intellectual quotient (IQ) with patient, epilepsy, and family factors. Family factors included parental education, household income, and validated parent-report measures of family functioning, family mastery and social support, and family demands. Univariable analyses showed that higher IQ scores were associated with an older age of epilepsy onset (β = .260, p = .009), fewer antiepileptic drugs (β = .248, p = .013), a shorter duration (β = .384, p < .001) and percentage of life with epilepsy (β = .419, p < .001), unilobar epileptogenic foci relative to multilobar foci (β = .274, p = .006), and lower family demands (β = .211, p = .035). In multivariable analysis, unilobar epileptogenic foci (p = .010) and a shorter percentage of life with epilepsy (p = .001) remained significant predictors of IQ. Exploratory moderation analyses found the relationship between the extent of epileptogenic foci and IQ to be moderated by family demands (p = .004); specifically, patients with unilobar epileptogenic onset had similar IQ scores irrespective of family demands, whereas patients with multilobar foci had lower IQ scores with increasing family demands. Family factors did not have a large impact on IQ among children with medically refractory epilepsy, although the moderating effect of family demands deserves further study. Epilepsy-related factors in this patient group may weaken the link between child IQ and family factors. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Non-pharmacological treatment options for refractory epilepsy: an overview of human treatment modalities and their potential utility in dogs.

Refractory epilepsy is a common disorder both in humans and dogs and treatment protocols are difficult to optimise. In humans, different non-pharmacological treatment modalities currently available include surgery, the ketogenic diet and neurostimulation. Surgery leads to freedom from seizures in 50-75% of patients, but requires strict patient selection. The ketogenic diet is indicated in severe childhood epilepsies, but efficacy is limited and long-term compliance can be problematic. In the past decade, various types of neurostimulation have emerged as promising treatment modalities for humans with refractory epilepsy. Currently, none of these treatment options are used in routine daily clinical practice to treat dogs with the condition. Since many dogs with poorly controlled seizures do not survive, the search for alternative treatment options for canine refractory epilepsy should be prioritised. This review provides an overview of non-pharmacological treatment options for human refractory epilepsy. The current knowledge and limitations of these treatments in canine refractory epilepsy is also discussed. Copyright © 2013 Elsevier Ltd. All rights reserved.

A challenge of modern cardiovascular medicine is to find new, effective treatments for patients with refractory angina pectoris, a clinical condition characterized by severe angina despite optimal medical therapy. These patients are not candidates for surgical or percutaneous revascularization. Herein we review the most up-to-date information regarding the modern approach to the patient with refractory angina pectoris, from conventional medical management to new medications and shock wave therapy, focusing on the use of endothelial precursor cells (EPCs) in the treatment of this condition. Clinical limitations of the efficiency of conventional approaches justify the search for new therapeutic options. Regenerative medicine is considered the next step in the evolution of organ replacement therapy. It is driven largely by the same health needs as transplantation and replacement therapies, but it aims further than traditional approaches, such as cell-based therapy. Increasing knowledge of the role of circulating cells derived from bone marrow (EPCs) on cardiovascular homeostasis in physiologic and pathologic conditions has prompted the clinical use of these cells to relieve ischemia. The current state of therapeutic angiogenesis still leaves many questions unanswered. It is of paramount importance that the treatment is delivered safely. Direct intramyocardial and intracoronary administration has demonstrated acceptable safety profiles in early trials, and may represent a major advance over surgical thoracotomy. The combined efforts of bench and clinical researchers will ultimately answer the question of whether cell therapy is a suitable strategy for treatment of patients with refractory angina.

Management of patients with chronic constipation (CC), irresponsive to medical treatment, is very difficult. There are some surgical approaches reported for the treatment. In this study we aimed to assess the results of different surgical procedures in patients with severe CC who were refractory to intensive medical treatments. Fifteen patients with refractory chronic constipation underwent surgical management between 1998 and 2003 in Ankara University School of Medicine Department of General Surgery. Median age of the patients was 40 years (range, 24-77), female/male ratio was 11/4, median duration of symptoms was 13 years (range, 4-35 years) and median interval of two subsequent bowel movements was 15 (range, 5-30) days. Preoperative evaluation including barium enema, colonoscopy, colonic transit time, and cinedefecography and balloon expulsion test were done in all patients. Clinical analysis of constipation with these tests indicated a simple slow transit colon in three patients but more complicated variations of combined anatomical functional disorders in the rest of the cases. Surgical procedures consisted of total colectomy, Frykman-Goldberg procedure, Wells procedure and appendisostomy, laparoscopically in 8 of them. Deep vein thrombosis developed in the postoperative period after rectopexy and pelvic floor repair in one case. The median follow-up time was 5.5 years. Fourteen (93.3%) patients had an excellent bowel movement and were highly satisfied with the surgical management. Surgical interventions may be beneficial in selected patients with refractory chronic constipation (Tab. 2, Ref. 13). Full Text (Free, PDF) www.bmj.sk.

Rituximab (RTX) is effective for treating childhood refractory nephrotic syndrome (NS), such as steroid-dependent (SD), frequently relapsing (FR), and steroid-resistant (SR) NS. While RTX has been proven to be effective in treating SDNS, FRNS, and SRNS, it may cause serum sickness, a rare illness characterized by fever, rash, and arthralgia, 10-14 days after primary antigen exposure or within a few days after secondary antigen exposure, by producing human anti-chimeric antibodies (HACAs). A 17-year-old girl with refractory SDNS treated with RTX and oral cyclosporine A was admitted with fever and arthralgia 10 days after the fifth RTX dose was administered. After RTX was started when she was 14-years-old, SDNS remission was then achieved, and prednisolone was discontinued. Although antibiotics and non-steroidal anti-inflammatory agents were administered, fever and arthralgia continued. After various inspections and clinical course, we considered her as RTX-induced serum sickness (RISS). The patient had an elevated HACA level and was diagnosed with RISS. Fever and arthralgia disappeared 5 days after onset. To the best of our knowledge, this is the first reported case of RISS with NS. Fever, rash, and arthralgia after RTX administration can be the initial symptoms.

Purpose: To evaluate the response rate (RR) and time to local recurrence (TTLR) among patients who received salvage radiation therapy for relapsed or refractory aggressive non-Hodgkin lymphoma (NHL) and investigate whether RR and TTLR differed according to disease characteristics. Methods and Materials: A retrospective review was performed for all patients who completed a course of salvage radiation therapy between January 2001 and May 2011 at Brigham and Women's Hospital/Dana-Farber Cancer Institute. Separate analyses were conducted for patients treated with palliative and curative intent. Predictors of RR for each subgroup were assessed using a generalized estimating equation model. For patients treatedmore » with curative intent, local control (LC) and progression-free survival were estimated with the Kaplan-Meier method; predictors for TTLR were evaluated using a Cox proportional hazards regression model. Results: Salvage radiation therapy was used to treat 110 patients to 121 sites (76 curative, 45 palliative). Salvage radiation therapy was given as part of consolidation in 18% of patients treated with curative intent. Median dose was 37.8 Gy, with 58% and 36% of curative and palliative patients, respectively, receiving 39.6 Gy or higher. The RR was high (86% curative, 84% palliative). With a median follow-up of 4.8 years among living patients, 5-year LC and progression-free survival for curative patients were 66% and 34%, respectively. Refractory disease (hazard ratio 3.3; P=.024) and lack of response to initial chemotherapy (hazard ratio 4.3; P=.007) but not dose (P=.93) were associated with shorter TTLR. Despite doses of 39.6 Gy or higher, 2-year LC was only 61% for definitive patients with refractory disease or disease that did not respond to initial chemotherapy. Conclusions: Relapsed or refractory aggressive NHL is responsive to salvage radiation therapy, and durable LC can be achieved in some cases. However, refractory disease is associated with a shorter TTLR, suggesting that radiation dose escalation, addition of radiosensitizers, or a combination of both may be indicated in these patients.« less

Abstract Surgery for refractory epilepsy is widely used but the efficacy of this treatment for providing a seizure-free outcome and better quality of life remains unclear. This study aimed to update current evidence and to evaluate the effects of surgery on quality of life in patients with refractory epilepsy. A systematic review and meta-analysis of the literature were conducted and selected studies included 2 groups of refractory epilepsy patients, surgical and nonsurgical. The studies were assessed using the Newcastle–Ottawa Scale. The primary outcome was the seizure-free rate. The secondary outcome was quality of life. Adverse events were also reviewed. After screening, a total of 20 studies were selected: 8 were interventional, including 2 randomized controlled trials, and 12 were observational. All of the studies comprised 1959 patients with refractory epilepsy. The seizure-free rates were significantly higher for patients who received surgery compared with the patients who did not; the combined odds ratio was 19.35 (95% CI = 12.10–30.95, P < 0.001). After adjusting for publication bias the combined odds ratio was 10.25 (95% CI = 5.84–18.00). In both the interventional and observational studies, patients treated surgically had a significantly better quality of life compared with the patients not treated surgically. Complications were listed in 3 studies and the rates were similar in surgical and nonsurgical patients. Our meta-analysis found that for patients with refractory epilepsy, surgical treatment appears to provide a much greater likelihood of seizure-free outcome than nonsurgical treatment, although there is a need for more studies, particularly randomized studies, to confirm this conclusion. Based on more limited data, surgical treatment also appeared to provide a better quality of life and did not seem to increase complications. PMID:25674741

Gastric electric stimulation (GES) is used to treat patients with refractory gastroparesis symptoms. However, the effectiveness of GES in clinical practice and the effect of GES on specific symptoms of gastroparesis are not well delineated. To determine the effectiveness of GES for treatment for refractory symptoms of gastroparesis, the improvement in specific symptoms of gastroparesis, and clinical factors impacting on outcome. Enterra GES was used to treat refractory gastroparesis symptoms. Patients filled out a symptom severity questionnaire (PAGI-SYM) prior to insertion. At each follow-up visit, the patient filled out PAGI-SYM and assessed their therapeutic response using the Clinical Patient Grading Assessment Scale (CPGAS). One hundred and fifty-one patients (120 females) with refractory gastroparesis (72 diabetic, 73 idiopathic, 6 other) underwent GES. Of the 138 with follow-up (1.4 ± 1.0 years), the average CPGAS was 2.4 ± 0.3 (SEM): 104 patients (75 %) improved (CPGAS > 0) and 34 (25 %) did not (CPGAS ≤ 0). Sixty patients (43 %) were at least moderately improved (CPGAS score ≥4). Clinical improvement was seen in both diabetic and idiopathic patients with the CPGAS in diabetic patients (3.5 ± 0.3) higher in idiopathic patients (1.5 ± 0.5; p < 0.05). Symptoms significantly improving the most included nausea, loss of appetite, and early satiety. Vomiting improved in both diabetic and idiopathic patients although the diabetic subgroup experienced a significantly greater reduction in vomiting than the idiopathic subgroup. In this cohort of patients with refractory gastroparesis, GES improved symptoms in 75 % of patients with 43 % being at least moderately improved. Response in diabetics was better than in nondiabetic patients. Nausea, loss of appetite, and early satiety responded the best.

Since its introduction by Leksell, Gamma Knife radiosurgery (GKRS) has become increasingly popular as a management approach for patients diagnosed with trigeminal neuralgia (TN). For this reason, we performed a modern review of the literature analyzing the efficacy of GKRS in the treatment of patients who suffer from TN. For patients with medically refractory forms of the condition, GKRS has proven to be an effective initial and repeat treatment option. Cumulative research suggests that patients treated a single time with GKRS exhibit similar levels of facial pain control when compared to patients treated multiple times with GKRS. However, patients treated on multiple occasions with GKRS are more likely to experience facial numbness and other facial sensory changes when compared to patients treated once with GKRS. Although numerous articles have reported MVD to be superior to GKRS in achieving facial pain relief, the findings of these comparison studies are weakened by the vast differences in patient age and comorbidities between the two studied groups and cannot be considered conclusive. Questions remain regarding optimal GKRS dosing and targeting strategies, which warrants further investigation into this controversial matter. PMID:22229034

Deep brain stimulation (DBS) is an increasingly utilized therapeutic modality for the management of medication refractory essential tremor (ET). The aim of this study was to determine whether DBS allowed for anti-tremor medication reduction within the year after the procedure was performed. We conducted a retrospective chart review and telephone interviews on 34 consecutive patients who had been diagnosed with ET, and who had undergone unilateral DBS surgery. Of the 34 patients in our cohort, 31 patients (91%) completely stopped all anti-tremor medications either before surgery (21 patients, 62%) or in the year following DBS surgery (10 patients, 29%). Patients who discontinued tremor medications before DBS surgery did so because their tremors either became refractory to anti-tremor medication, or they developed adverse events to tremor medications. Patients who stopped tremor medications after DBS surgery did so due to sufficient tremor control. Only three patients (9%) who were taking tremor medications at the time of surgery continued the use of a beta-blocker post-operatively for the purpose of hypertension management in all cases. The data from this study indicate that medication cessation is common following unilateral DBS for ET.

2012-01-01

This article focuses on the pathogenesis, clinical manifestations, and various treatment modalities for acute hyperkalemia and presents a systematic approach to selecting a treatment strategy. Hyperkalemia, a life-threatening condition caused by extracellular potassium shift or decreased renal potassium excretion, usually presents with non-specific symptoms. Early recognition of moderate to severe hyperkalemia is vital in preventing fatal cardiac arrhythmias and muscle paralysis. Management of hyperkalemia includes the elimination of reversible causes (diet, medications), rapidly acting therapies that shift potassium into cells and block the cardiac membrane effects of hyperkalemia, and measures to facilitate removal of potassium from the body (saline diuresis, oral binding resins, and hemodialysis). Hyperkalemia with potassium level more than 6.5 mEq/L or EKG changes is a medical emergency and should be treated accordingly. Treatment should be started with calcium gluconate to stabilize cardiomyocyte membranes, followed by insulin injection, and b-agonists administration. Hemodialysis remains the most reliable method to remove potassium from the body and should be used in cases refractory to medical treatment. Prompt detection and proper treatment are crucial in preventing lethal outcomes. PMID:23882341

Though it is rare, isolated interrupted aortic arch (IAA) could lead to hypertension. Surgical repair is the only effective curative method to treat IAA conditions and patients with IAA can hardly survive to adulthood with medication alone. We report an IAA case that of a 45-year-old male patient who survived for 45 years without surgical treatment. A 45-year-old man was referred to the hospital presenting with abnormal blood pressure level. Both computed tomography angiogram (CTA) and angiography revealed IAA. The patient was diagnosed as IAA based on computed tomography angiogram (CTA) and angiography. The patient's blood pressure was severely high and refractory. He refused surgical treatment and accepted antihypertensive medication for 10 days. The patient's office blood pressure level was abnormal, fluctuating between 140/90 and 160/100 mm Hg, but 24-hour ambulatory blood pressure monitoring showed normal level. Hypertension due to IAA could be controlled with medications, even surgery is not performed. The discrepancy between ambulatory and office blood pressure levels may be due to the white coat effect.

Psychosocial functioning in adolescents with complex partial seizures.

Elliott, I

1992-03-01

This pilot study examined psychosocial functioning in adolescents (age 12.5-18.5 years) with complex partial seizures. Twenty-five subjects were divided into three groups: Group I (N = 11), medically treated with uncontrolled seizures; Group II (N = 6), medically managed with controlled seizures; and Group III (N = 8), epilepsy refractory to medical management with seizure control following surgery. Psychosocial functioning was measured using the "Adolescent Psychosocial Inventory" of Batzel and Dodrill. Findings revealed significant differences (F 4.80. p less than 0.02) in psychosocial functioning between the three groups. Group I showed the poorest overall adjustment; Group II, the best adjustment; Group III was better adjusted than Group I, but less than Group II. Significant difficulties were evident in the areas of school, interpersonal, emotional, seizure adjustment and overall psychosocial functioning in Group III. No problems were evident in Group II. School, emotional and overall adjustment were moderately problematic in Group III. Analysis of biological and demographic data revealed a significant association between increased numbers of medications and poorer psychosocial functioning (r = 58, p less than 0.02). The study results provide direction for clinic and community nurse specialists to set priorities with regard to assessment and supportive interventions.

Initial treatment of chronic phase chronic myeloid leukaemia is straightforward in today's era of tyrosine kinase inhibitors. However, managing refractory cases remain a major challenge due to the multiple factors that can influence decision-making, including medication tolerance, disease burden, mutation status, comorbidities, availability of donor, and fitness for an ablative conditioning. We report a male patient presenting with chronic phase chronic myeloid leukaemia who was treated with 5 different tyrosine kinase inhibitors either due to intolerance and/or failed response. He subsequently received 2 haploidentical haematopoietic stem cells transplants before achieving complete remission. This case highlights various treatment options, need for vigilant disease monitoring, and the possibility of complete positive response even after many lines of therapy failure. 2016 BMJ Publishing Group Ltd.

Gastroesophageal reflux disease is one of the most common comorbidities in patients with asthma. Gastroesophageal reflux disease can be linked to difficult-to-control asthma. Current management includes gastric acid suppression therapy and surgical antireflux procedures. The LINX® procedure is a novel surgical treatment for patients with gastroesophageal reflux disease refractory to medical therapy. To the best of our knowledge, we report the first case of successful treatment of refractory asthma secondary to gastroesophageal reflux disease using the LINX® procedure. Our patient was a 22-year-old white woman who met the American Thoracic Society criteria for refractory asthma that had remained poorly controlled for 5 years despite progressive escalation to step 6 treatment as recommended by National Institutes of Health-National Asthma Education and Prevention Program guidelines, including high-dose oral corticosteroids, high-dose inhaled corticosteroid plus long-acting β2-agonist, leukotriene receptor antagonist, and monthly omalizumab. Separate trials with azithromycin therapy and roflumilast did not improve her asthma control, nor did bronchial thermoplasty help. Additional consultations with two other university health systems left the patient with few treatment options for asthma, which included cyclophosphamide. Instead, the patient underwent a LINX® procedure after failure of maximal medical therapy for gastroesophageal reflux disease with the additional aim of improving asthma control. After she underwent LINX® treatment, her asthma improved dramatically and was no longer refractory. She had normal exhaled nitric oxide levels and loss of peripheral eosinophilia after LINX® treatment. Prednisone was discontinued without loss of asthma control. The only immediate adverse effects due to the LINX® procedure were bloating, nausea, and vomiting. LINX® is a viable alternative to the Nissen fundoplication procedure for the treatment of patients with gastroesophageal reflux disease and poorly controlled concomitant refractory asthma.

Management of refractory inflammatory bowel disease (IBD) in children is challenging and once response to conventional medical therapy deviates from the expected, options are often limited. Sirolimus is commonly used in post-transplantation management and is used sparsely as rescue therapy in refractory Crohn's disease. In the present study, we report the efficacy of sirolimus as an adjuvant immunosuppressive therapy in a retrospective case review of a selected group of IBD children who were refractory to the conventional treatments. Medical records of children with refractory IBD unresponsive to conventional therapy and started on sirolimus between 2006 and 2012 were retrospectively reviewed. Clinical response, through Pediatric Ulcerative Colitis Activity Index (PUCAI) and Pediatric Crohn's Disease Activity Index (PCDAI), as well as intestinal inflammation, through specific histological scores, was evaluated. The records of 14 patients were analyzed. Eleven of them had ulcerative colitis (UC) and 3 Crohn's disease (CD); mean age at diagnosis was 9.1 years (standard deviation 3.8). Of UC patients, 5 (45%) achieved clinical remission and 2 (18%) showed clinical response. All CD patients went into clinical remission. Mucosal healing was achieved by 5 children (45%) with UC and 2 (67%) with CD patients. One child with ulcerative colitis was weaned off adalimumab, while 2 children with CD were weaned off prednisolone and methotrexate successfully. Our data provide evidence that sirolimus seems to be effective as rescue therapy in a subgroup of children with severe IBD refractory to conventional therapies by inducing both clinical remission and mucosal healing.

To report the development of subretinal fibrosis after the injection of intravitreal bevacizumab in eyes with proliferative diabetic retinopathy (PDR) refractory to panretinal laser photocoagulation (PRP). Twenty-one eyes of 15 patients treated with PRP and intravitreal injection of bevacizumab were included in this study. The clinical outcomes of 21 eyes having subretinal fibrosis after intravitreal bevacizumab injection were reviewed. There were 9 men and 6 women with a mean age of 51.3 +/- 8.9 years. All eyes had PDR refractory to panretinal photocoagulation and were treated with at least one intravitreal injection of 1.25 mg of bevacizumab (mean number of injections: 1.8). Before injection, there was subretinal fibrosis in 5 eyes and vitreoretinal traction in 19 eyes. After a mean follow-up period of 7 months, the development or progression of subretinal fibrosis was detected in all eyes. Intravitreal injection of bevacizumab may cause formation or progression of subretinal fibrosis in patients with PDR refractory to PRP. Copyright 2010, SLACK Incorporated.

Role of Cholestyramine in Refractory Hyperthyroidism: A Case Report and Literature Review.

PubMed

Alswat, Khaled A

2015-07-24

Hyperthyroidism is a common disease that usually responds to the conventional therapy of anti-thyroidal medications (methimazole or PTU) and beta-blocker. Refractory hyperthyroidism is a rare condition in which hyperthyroidism fails to respond to the above therapy. Cholestyramine has been shown to decrease thyroid hormone level when added to the ongoing anti-thyroidal medications. A 52-year-old woman with past medical history of enlarging goiter presented with obstructive symptoms of worsening shortness of breath and snoring. Admission thyroid function test showed mild hyperthyroidism (suppressed TSH, slightly high FT4, and high normal FT3) that worsened after she received a CT scan with contrast and failed to respond to a 3-week course of high-dose dexamethasone, high-dose carbimazole, and up-titrated propranolol. Five days after cholestyramine was added, her FT4 decreased by 30% and normalized after 12 days. The patient underwent total thyroidectomy as definitive treatment for the hyperthyroidism and for the obstructive symptoms. Cholestyramine is an effective additional treatment for hyperthyroidism and may be an effective treatment for refractory iodine-induced hyperthyroidism. The possibility of self-remission (natural course) is less likely given the dramatic and rapid response to cholestyramine.

Clofarabine, one of the key treatment agents for refractory and relapsed acute lymphoblastic leukemia (ALL), achieves a remission rate of approximately 30% with single-agent clofarabine induction chemotherapy. However, a remission rate of approximately 50% was reported with a combination chemotherapy regimen consisting of clofarabine, etoposide, and cyclophosphamide. We treated two cases with refractory and relapsed ALL with combination chemotherapy including clofarabine; one was an induction failure but the other achieved remission. Both cases developed an infectious complication (NCI-CTCAE grade 3) and body pain with infusion. Prophylactic antibiotic and opioid infusions facilitated avoiding septic shock and pain. Further investigation of such cases is required.

Recently, sirolimus, an inhibitor of mammalian target of rapamycin, was reported to decrease chylous effusion in patients with lymphangioleimyomatosis (LAM). We herein report a case of a 34-year-old woman with LAM who developed refractory chylothorax and chylous ascites during sirolimus therapy. In this case, to reduce chylous effusion, we administered octreotide, which is often used to control postoperative chylous effusion, in addition to the sirolimus therapy. This combination therapy reduced the chylothorax and chylous ascites. For patients with LAM, octreotide therapy in addition to sirolimus may be effective for treating sirolimus-refractory chylous effusion.

Permanent catheters for recurrent ascites-a critical and systematic review of study methodology.

PubMed

Christensen, Lars; Wildgaard, Lorna; Wildgaard, Kim

2016-06-01

Management of refractory ascites traditionally includes medical treatment with diuretics or intermittent paracentesis. Patients with recurrent ascites may benefit from the use of permanent intra-abdominal catheters with more frequent drainage without hospitalization. The objective was to systematically asses the methodology of factors and endpoints reported in studies investigating permanent catheters for recurrent ascites treatment. Using a systematic search strategy, we critically assessed the methodology when treating refractory ascites using a permanent catheter. Studies critically assessed included both retro- and prospective studies. A total of 715 unique articles were found via PubMed, The Cochrane Library and Embase. Twenty-nine studies (tunnelled catheter = 12, peritoneal ports = 6 and peritoneovenous shunts = 11) with three distinct types of permanent catheters fulfilled the inclusion criteria. Only three studies reported technical success less than 100 %. Data on complications and treatment were not available in all papers; peritonitis (48 %), cellulitis (41 %), prophylactic antibiotics (48 %) and complications to catheter insertion were difficult to distinguish from advanced co-morbidity of patients. Thirteen studies (45 %) reported some type of evaluating patient experience or functional outcome, but only three studies used validated reproducible scales when assessing outcomes. Fifteen of the 29 studies included 30 patients or less. Knowledge is limited because complications and outcomes are poorly defined. The expected increase in catheter treatment of refractory ascites necessitates comparative studies, using validated patient-related outcomes, and the reporting of unambiguous complications. A proposal of variables to include in future studies is presented.

The aim was to determine differences of clinical, treatment and outcome characteristics between patients with in-hospital and out-of-hospital status epilepticus (SE). From 2005 to 2014, clinical data were assessed in adults with SE treated in an academic medical care centre. Clinical characteristics, treatment and outcomes were compared between patients with in-hospital and out-of-hospital SE. Amongst 352 patients, 213 were admitted with SE and 139 developed in-hospital SE. Patients with in-hospital SE had more acute/fatal aetiologies (60% vs. 35%, P < 0.001), fewer previous seizures (33% vs. 50%, P = 0.002), a higher median Charlson Comorbidity Index (3 vs. 2, P < 0.001), longer median SE duration (1 vs. 0.5 days, P = 0.001), more refractory SE (52% vs. 39%, P = 0.022), less return to functional baseline (38% vs. 54%, P = 0.006) and increased mortality (29% vs. 19%, P = 0.001). Whilst in multivariable analyses an increasing Status Epilepticus Severity Score (STESS) was an independent predictor for death in both groups, increased Charlson Comorbidity Index and treatment refractory SE were associated with death only in patients with in-hospital SE. Continuous anaesthesia for refractory SE was associated with increased mortality only in patients with out-of-hospital SE. The area under the receiver operating curve was 0.717 for prediction of death by STESS in patients with in-hospital SE and 0.811 in patients with out-of-hospital SE. Patients with in-hospital SE had more fatal aetiologies and comorbidities, refractory SE, less return to functional baseline, and increased mortality compared to patients with out-of-hospital SE. Whilst the STESS was a robust predictor for death in both groups, the association between continuous anaesthesia and death was limited to out-of-hospital SE. © 2017 EAN.

Functional neurologic outcome for children with refractory and super-refractory status epilepticus has not been well defined. Retrospective chart review including children age 0-17 years who received pentobarbital infusion from 2003 to 2016 for status epilepticus. Outcomes were defined in terms of mortality, need for new medical technology assistance at hospital discharge and functional neurologic outcome determined by pediatric cerebral performance category score (PCPC). Potential patient characteristics associated with functional neurologic outcome including age, sex, ethnicity, etiology of the status epilepticus, and duration of pentobarbital infusion were evaluated. Forty children met inclusion criteria. In-hospital mortality was 30% (12/40). Of survivors, 21% (6/28) returned to baseline PCPC while half (14/28) declined in function ≥ 2 PCPC categories at hospital discharge. 25% (7/28) of survivors required tracheostomy and 27% (7/26) required new gastrostomy. Seizures persisted at discharge for most patients with new onset status epilepticus while the majority of patients with known epilepsy returned to baseline seizure frequency. Etiology (p = 0.015), PCPC at admission (p = 0.0006), new tracheostomy (p = 0.012), and new gastrostomy tube (p = 0.012) were associated with increase in PCPC score ≥ 2 categories in univariable analysis. Duration of pentobarbital infusion (p = 0.005) and length of hospital stay (p = 0.056) were longer in patients who demonstrated significant decline in neurologic function. None of these variables maintained statistical significance when multiple logistic regression model adjusting for PCPC score at admission was applied. At long-term follow-up, 36% (8/22) of children demonstrated improvement in PCPC compared to discharge and 23% (5/22) showed deterioration including three additional deaths. Mortality in this population was high. The majority of children experienced some degree of disability at discharge. Despite prolonged pentobarbital infusion, there were cases of survival with good neurologic outcome.

The epidemiology of in-hospital death after pediatric sepsis has not been well characterized. We investigated the timing, cause, mode, and attribution of death in children with severe sepsis, hypothesizing that refractory shock leading to early death is rare in the current era. Retrospective observational study. Emergency departments and ICUs at two academic children's hospitals. Seventy-nine patients less than 18 years old treated for severe sepsis/septic shock in 2012-2013 who died prior to hospital discharge. None. Time to death from sepsis recognition, cause and mode of death, and attribution of death to sepsis were determined from medical records. Organ dysfunction was assessed via daily Pediatric Logistic Organ Dysfunction-2 scores for 7 days preceding death with an increase greater than or equal to 5 defined as worsening organ dysfunction. The median time to death was 8 days (interquartile range, 1-12 d) with 25%, 35%, and 49% of cumulative deaths within 1, 3, and 7 days of sepsis recognition, respectively. The most common cause of death was refractory shock (34%), then multiple organ dysfunction syndrome after shock recovery (27%), neurologic injury (19%), single-organ respiratory failure (9%), and nonseptic comorbidity (6%). Early deaths (≤ 3 d) were mostly due to refractory shock in young, previously healthy patients while multiple organ dysfunction syndrome predominated after 3 days. Mode of death was withdrawal in 72%, unsuccessful cardiopulmonary resuscitation in 22%, and irreversible loss of neurologic function in 6%. Ninety percent of deaths were attributable to acute or chronic manifestations of sepsis. Only 23% had a rise in Pediatric Logistic Organ Dysfunction-2 that indicated worsening organ dysfunction. Refractory shock remains a common cause of death in pediatric sepsis, especially for early deaths. Later deaths were mostly attributable to multiple organ dysfunction syndrome, neurologic, and respiratory failure after life-sustaining therapies were limited. A pattern of persistent, rather than worsening, organ dysfunction preceded most deaths.

Background Palliative oxygen therapy is widely used for dyspnea in individuals with life-limiting illness ineligible for long-term oxygen therapy. Methods This international double-blind randomized controlled trial evaluatedeffectiveness of oxygen vs. medical (room) air for relieving breathlessness in patients with life-limiting illness, refractory dyspnea, and PaO2>55 mm Hg. Participants were recruited from outpatient clinics at 9 sites (Australia, United States, England). Participants received oxygen or medical air via concentrator through nasal cannulae at 2 liters/minute for 7 days. The primary outcome measure was breathlessness (0-10 numerical rating scale [NRS]), measured twice daily. Findings Participants (N=239) were: mean age, 73 (standard deviation [SD] 10); 62% male; mean PaO2, 77 mm Hg (SD 12); mean morning dyspnea, 4.5 on NRS (SD 2.2); chronic obstructive pulmonary disease, 64%; cancer, 16%. Oxygen was not significantly superior to medical air for relief of breathlessness. Over the 7-day period, after provision of medical gas, mean morning and evening dyspnea decreased by -0.8 (95% confidence interval [CI]: -1.1, -0.5) and -0.4 (CI: -0.7, 0.1), respectively (p<0.001), regardless of intervention. Baseline dyspnea predicted improvement with medical gas; participants with moderate (4-6 NRS) and severe (7-10 NRS) baseline dyspnea had average decreases in morning dyspnea of -0.7 (CI: -1.1, -0.4) and -2.4 (CI: -3.0, -1.8), respectively. Interpretation There is no additional symptomatic benefit of oxygen over room air delivered by nasal cannulae for relieving refractory dyspnea related to life-limiting illness in patients with PaO2>55 mm Hg. Dyspnea intensity decreased in both study arms, temporally related to provision of medical gas. PMID:20816546

To describe the novel use of high-dose insulin (HDI) therapy and intravenous lipid emulsion (ILE) to treat refractory, severe diltiazem toxicosis in a dog. A 4-year-old Pomeranian was presented for treatment 2.5 hours following ingestion of a diltiazem extended-release capsule. Toxic ingestion was calculated at a maximum exposure of 79 mg/kg, with a reported canine LD50 of 50 mg/kg. Clinical signs of progressive hypotension and severe bradycardia with atrial standstill were observed, which persisted despite treatment with atropine, calcium, glucagon, and dopamine. The novel use of HDI and ILE as part of therapy for diltiazem toxicosis resulted in clinical resolution of life-threatening signs. Within 1 hour of initiating HDI therapy, the clinical signs improved, and with continued treatment, the patient remained normotensive and survived to discharge. To the authors' knowledge, this is the first reported clinical case describing the use of both HDI and ILE therapy in the treatment of severe refractory diltiazem toxicosis in veterinary medicine. No significant adverse effects were observed from the treatment. In veterinary patients with severe refractory calcium channel blocker toxicosis, the use of HDI and ILE should be considered for life-threatening clinical signs. © Veterinary Emergency and Critical Care Society 2013.

This study analyzes the efficacy and safety of a retrievable, fully covered self-expanding metal stent (cSEMS) in the treatment of refractory benign esophageal restenosis in children. This is a retrospective analysis of the application of a newly designed cSEMS in treating refractory benign postoperative restenosis in five children with ages ranging from 16 months to 8 years. Efficacy and safety were evaluated during the follow-up period. cSEMS with or without an antireflux valve at the distal end were successfully placed and removed in five children. These five patients were followed up for 4-12 months after stent removal. Among the five patients, ulcerative stricture was observed in two patients because of reflux esophagitis, while three patients showed no signs of stricture recurrence. Stent migration was observed in three patients, two of which required the stent to be reset. The narrow esophagus was successfully expended to a diameter of 12-13 mm. Besides the observation of mild granulation tissue growth in one case, no severe complications were observed during surgery and after stent placement. Our study suggests that a retrievable, fully covered SEMS is safe and partially effective for treating refractory benign postoperative esophageal restenosis in children during short-term observation. © 2013.

Midazolam fails to prevent neurological damage in children with convulsive refractory febrile status epilepticus.

We conducted a retrospective study to compare the outcome of intravenous midazolam infusion without electroencephalography or targeted temperature management and barbiturate coma therapy with electroencephalography and targeted temperature management for treating convulsive refractory febrile status epilepticus. Of 49 consecutive convulsive refractory febrile status epilepticus patients admitted to the pediatric intensive care unit of our hospital, 29 were excluded because they received other treatments or because of various underlying illnesses. Thus, eight patients were treated with midazolam and 10 with barbiturate coma therapy using thiamylal. Midazolam-treated patients were intubated only when necessary, whereas barbiturate coma therapy patients were routinely intubated. Continuous electroencephalography monitoring was utilized only for the barbiturate coma group. The titration goal for anesthesia was clinical termination of status epilepticus in the midazolam group and suppression or burst-suppression patterns on electroencephalography in the barbiturate coma group. Normothermia was maintained using blankets and neuromuscular blockade in the barbiturate coma group and using antipyretics in the midazolam group. Prognoses were measured at 1 month after onset; children were classified into poor and good outcome groups. Good outcome was achieved in all the barbiturate coma group patients and 50% of the midazolam group patients (P = 0.02, Fisher's exact test). Although the sample size was small and our study could not determine which protocol element is essential for the neurological outcome, the findings suggest that clinical seizure control using midazolam without continuous electroencephalography monitoring or targeted temperature management is insufficient in preventing neurological damage in children with convulsive refractory febrile status epilepticus.

To report on a wearer of rigid gas-permeable contact lenses with a keratomycosis due to Tintelnotia-a new genus of Phaeosphaeriaceae-treated with terbinafine and polyhexamethylene biguanide. Chart review of a patient with fungal keratitis treated additionally with systemic and topical terbinafine 0.25% after symptoms increased under conventional antimycotic therapy with voriconazole. Antifungal susceptibility had been tested in vitro. After starting an additional treatment with systemic and topical terbinafine, the severe corneal infection was sufficiently resolved. The drug was well tolerated without any neurological, dermatological or gastroenterological problems. Terbinafine revealed a marked in vitro antifungal activity of 0.12 µg/ml. The fungus was identified as Tintelnotia destructans. Terbinafine might be considered as a therapeutic option in severe cases of fungal keratitis refractory to common antifungal therapy.

Refractory chronic cough due to gastroesophageal reflux is a troublesome condition unresponsive to the standard medical anti-reflux therapy. Its underlying mechanisms may include incomplete acid suppression, non-acid reflux, transient lower esophageal sphincter relaxations and esophageal hypersensitivity. The diagnosis of this disorder depends on both the findings of multi-channel intraluminal impedance-pH monitoring and the subsequent intensified anti-reflux therapy. The strategies of pharmacological treatment for refractory chronic cough due to reflux include the optimization of proton pump inhibitors and add-on therapies with histamine H2 receptor antagonists, baclofen and gabapentin. However, the further study is needed to satisfy its management. PMID:26413488

A 65-year-old woman with recurrent breast cancer was repeatedly treated with bevacizumab, an anti-VEGF antibody. In addition, she was also frequently prescribed a nonsteroidal anti-inflammatory drug for abdominal pain. Melena was revealed 2 months after the final treatment with bevacizumab, and an endoscopic study revealed a duodenal ulcer (DU) that was resistant to anti-ulcer therapy. A cholangiography identified a biliary-duodenal fistula with bile juice leaking from the ulcer base. Therefore, a biliary stent was placed into the common bile duct for 3 months until the DU healed. This is the first case of a refractory DU with a biliary-duodenal fistula in a patient treated with bevacizumab.

Despite the increased use of rescue medical therapies for steroid refractory acute severe ulcerative colitis, mortality related to this entity still remains high. We aimed to assess the mortality and morbidity related to colectomy and their predictive factors in steroid refractory acute severe ulcerative colitis, and to evaluate the changes in mortality rates, complications, indications of colectomy, and the use of rescue therapy over time. We performed a multicenter observational study of patients with steroid refractory acute severe ulcerative colitis requiring colectomy, admitted to 23 Spanish hospitals included in the ENEIDA registry (GETECCU) from 1989 to 2014. Independent predictive factors of mortality were assessed by binary logistic regression analysis. Mortality along the study was calculated using the age-standardized rate. During the study period, 429 patients underwent colectomy, presenting an overall mortality rate of 6.3% (range, 0-30%). The main causes of death were infections and post-operative complications. Independent predictive factors of mortality were: age ≥50 years (OR 23.34; 95% CI: 6.46-84.311; p < 0.0001), undergoing surgery in a secondary care hospital (OR 3.07; 95% CI: 1.01-9.35; p = 0.047), and in an emergency setting (OR 10.47; 95% CI: 1.26-86.55; p = 0.029). Neither the use of rescue medical treatment nor the type of surgical technique used (laparoscopy vs. open laparotomy) influenced mortality. The proportion of patients undergoing surgery in an emergency setting decreased over time (p < 0.0001), whereas the use of rescue medical therapy prior to colectomy progressively increased (p > 0.001). The mortality rate related to colectomy in steroid refractory acute severe ulcerative colitis varies greatly among hospitals, reinforcing the need for a continuous audit to achieve quality standards. The increasing use of rescue therapy is not associated with a worse outcome and may contribute to reducing emergency surgical interventions and improve outcomes.

SU-F-T-647: Linac-Based Stereotactic Radiosurgery (SRS) in the Treatment of Trigeminal Neuralgia: Detailed Description of SRS Procedural Technique and Reported Clinical Outcomes

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pokhrel, D; Sood, S; Badkul, R

Purpose: SRS is an effective non-invasive alternative treatment modality with minimal-toxicity used to treat patients with medically/surgically refractory trigeminal neuralgia root(TNR) or those who may not tolerate surgical intervention. We present our linac-based SRS procedure for TNR treatment and simultaneously report our clinical outcomes. Methods: Twenty-eight TNR-patients treated with frame-based SRS at our institution (2009–2015) with a single-fraction point-dose of 60-80Gy to TNR were included in this IRB-approved study. Experienced neurosurgeon and radiation oncologist delineated the TNR on 1.0mm thin 3D-FIESTA-MRI that was co-registered with 0.7mm thin planning-CT. Treatment plans were generated in iPlan (BrainLAB) with a 4-mm diameter conemore » using 79 arcs with differential-weighting for Novalis-TX 6MV-SRS(1000MU/min) beam and optimized to minimize brainstem dose. Winston-Lutz test was performed before each treatment delivery with sub-millimeter isocenter accuracy. Quality assurance of frame placement was maintained by helmet-bobble-measurement before simulation-CT and before patient setup at treatment couch. OBI-CBCT scan was performed for patient setup verification without applying shifts. On clinical follow up, treatment response was assessed using Barrow Neurological Institute Pain Intensity Score(BNI-score:I–V). Results: 26/28 TNR-patients (16-males/10-females) who were treated with following single-fraction point-dose to isocenter: 80Gy(n=22),75Gy(n=1),70Gy(n=2) and 60Gy(n=1, re-treatment) were followed up. Median follow-up interval was 8.5-months (ranged:1–48.5months). Median age was 70-yr (ranged:43–93-yr). Right/left TNR ratio was 15/11. Delivered total # of average MUs was 19034±1204. Average beam-on-time: 19.0±1.3min. Brainstem max-dose and dose to 0.5cc were 13.3±2.4Gy (ranged:8.1–16.5Gy) and 3.6±0.4Gy (ranged:3.0–4.9Gy). On average, max-dose to optic-apparatus was ≤1.2Gy. Mean value of max-dose to eyes/lens was 0.26Gy/0.11Gy. Overall, 20-patients (77%) responded to treatment: 5(19%) achieved complete pain relief without medication (BNI score: I); 5(19%) had no-pain, decreased medication (BNI-score:II); 2(7.7%) had no-pain, but, continued medication (BNI-score:IIIA), and 8(30.8%) had pain that was well controlled by medication (BNI-score: IIIB). Six-patients (23.0%) did not respond to treatment (BNI-score:IV–V). Neither cranial nerve deficit nor radio-necrosis of temporal lobe was clinically observed. Conclusion: Linac-based SRS for medically/surgically refractory TNR provided an effective treatment option for pain resolution/control with very minimal if any normal tissue toxicity. Longer follow up of these patients is anticipated/needed to confirm our observations.« less

Epilepsy surgery is well established as safe and successful for children with temporal lobe epilepsy (TLE). Despite evidence from available data, there remains some reluctance to refer children with medically refractory epilepsy for preoperative evaluation and workup for possible surgery. To present the largest case series of pediatric (TLE) patients thus far, in order to better understand the predictability of preoperative evaluation on seizure outcome, and to better understand longitudinal outcomes in a large pediatric cohort. One hundred eighty-three pediatric patients with TLE who underwent surgical treatment between 1988 and 2012 were retrospectively reviewed. Preoperative seizure history, noninvasive and invasive preoperative evaluation, surgical results, pathological results, long-term seizure outcomes, and complications were evaluated. A review of pediatric TLE in the literature was also undertaken to better understand reported complications and long-term outcomes. Mean follow-up was 42 mo (range 12-152 mo); 155 patients had good seizure outcomes (Engel I/II; 84.8%) and 28 patients had poor seizure outcomes (Engel III/IV; 15.2%); 145 patients were Engel I (78.8%). Only 10 patients did not have worthwhile improvement (Engel class IV; 5.4%). A review of the literature identified 2089 unique cases of pediatric TLE. Satisfactory seizure outcomes occurred in 1629 patients (79%) with unsatisfactory outcomes in 433 patients (21%). Pediatric patients benefit from surgery for medically refractory TLE with an acceptable safety profile regardless of histopathological diagnosis, seizure frequency, or seizure type. Seizure freedom appears to have extensive durability in a significant proportion of surgically treated patients.

We describe a girl with Cushing disease for whom surgery and radiation treatments failed and the subsequent clinical course with mifepristone therapy. We present the patient's clinical, biochemical, and imaging findings. A 16-year-old girl presented with classic Cushing disease. After transsphenoidal surgery, Cyberknife radiosurgery, ketoconazole, and metyrapone did not control her disease, and she was prescribed mifepristone, which was titrated to a maximal dosage of 1200 mg daily with subsequent symptom improvement. Mifepristone (RU486) is a high-affinity, nonselective antagonist of the glucocorticoid receptor. There is limited literature on its use as an off-label medication to treat refractory Cushing disease. Over her 8-year treatment with mifepristone, her therapy was complicated by hypertension and hypokalemia requiring spironolactone and potassium chloride. She received a 2-month drug holiday every 4 to 6 months to allow for withdrawal menstrual bleeding with medroxyprogesterone acetate. Urinary cortisol, serum cortisol, and corticotropin levels remained elevated during mifepristone drug holidays. While on mifepristone, her signs and symptoms of Cushing disease resolved. Repeated magnetic resonance imaging demonstrated stable appearance of the residual pituitary mass. Bilateral adrenalectomy was performed, and mifepristone was discontinued after 95 months of medical therapy. We describe the longest duration of mifepristone therapy thus reported for the treatment of refractory Cushing disease. Mifepristone effectively controlled all signs and symptoms of hypercortisolism. Menstruating women who take the drug on a long-term basis should receive periodic drug holidays to allow for menses. The lack of reliable serum biomarkers to monitor the success of mifepristone therapy requires careful clinical judgment and may make its use difficult in Cushing disease.

Objective: To evaluate the risks of continuously administered IV anesthetic drugs (IVADs) on the outcome of adult patients with status epilepticus (SE). Methods: All intensive care unit patients with SE from 2005 to 2011 at a tertiary academic medical care center were included. Relative risks were calculated for the primary outcome measures of seizure control, Glasgow Outcome Scale score at discharge, and death. Poisson regression models were used to control for possible confounders and to assess effect modification. Results: Of 171 patients, 37% were treated with IVADs. Mortality was 18%. Patients with anesthetic drugs had more infections during SE (43% vs 11%; p < 0.0001) and a 2.9-fold relative risk for death (2.88; 95% confidence interval 1.45–5.73), independent of possible confounders (i.e., duration and severity of SE, nonanesthetic third-line antiepileptic drugs, and critical medical conditions) and without significant effect modification by different grades of SE severity and etiologies. As IVADs were used after first- and second-line drugs failed, there was a correlation between treatment-refractory SE and the use of IVADs, leading to insignificant results regarding the risk of IVADs and outcome after additional adjustment for refractory SE. Conclusion: Our findings heighten awareness regarding adverse effects of IVADs. Randomized controlled trials are needed to further clarify the association of IVADs with outcome in patients with SE. Classification of evidence: This study provides Class III evidence that patients with SE receiving IVADs have a higher proportion of infection and an increased risk of death as compared to patients not receiving IVADs.

Marginal ulcer is not infrequent after laparoscopic Roux-en-Y gastric bypass and could result in undesirable complications, such as intractability, bleeding, or perforation. Those patients who failed medical therapy, regarded as refractory marginal ulcers, may be considered as candidates for revisional surgery. Herein, we make a video presentation of a laparoscopic revisional procedure for refractory marginal ulcer. A 29-year-old morbidly obese woman (initial body mass index 37.1 kg/m(2)), a non-smoker, presented with persistent epigastric pain 3 months after initial laparoscopic Roux-en-Y gastric bypass at another institution. After an exhaustive work-up there, only the gastroendoscopy revealed a marginal ulcer and she underwent medical treatment (proton pump inhibitor and sucralfate) for 3 months, but the patient's symptom aggravated and the serial gastroendoscopies still confirmed the marginal ulcer without obvious resolution after a total of 4 months proton pump inhibitor therapy, suggesting failure of medical treatment and intractability. Laparoscopic revisional procedure with totally hand-sewn gastrojejunostomy and vagotomy was performed to relieve her intractable condition. The procedure took 130 min, without any intra-operative complications. Blood loss was 80 mL. The patient had an uneventful postoperative course, and the postoperative hospital stay was 3 days. She was relieved of her symptoms after this revisional surgery, and a subsequent gastroendoscopy 15 months later showed no marginal ulcers. Though long-term follow-up is needed to draw a definite conclusion, totally hand-sewn gastrojejunostomy and vagotomy remains a practicable revisional procedure to relieve refractory marginal ulcers.

Follicular lymphoma is characterized by a good response to immunochemotherapy (ICT). However, a small percentage of patients responds poorly to treatment and seems to have a worse outcome. This study attempted to identify the predictive factors and outcome of refractoriness to first-line ICT. All patients diagnosed with stage II to IV follicular lymphoma between 2002 and 2014 and treated with first-line ICT in 4 Spanish institutions were analyzed. Those with no response or progression or relapse within 6 months of first-line response assessment were considered ICT refractory. Three hundred forty-three patients were included (median age 58 years, 48% male), of whom 53 (15%) were ICT refractory. On multivariate analysis, high-risk follicular lymphoma international prognostic index (FLIPI) score, B symptoms, and elevated β2-microglobulin were correlated with refractoriness, and refractoriness, high-risk FLIPI score, and β2-microglobulin were correlated with overall survival (OS). Compared with ICT-sensitive, ICT-refractory patients had a higher incidence of histological transformation (5-year cumulative incidence 25% [14%-39%] vs. 6% [3%-10%], P < .001), a higher rate of refractoriness to second-line therapy (16/33 [48%] vs. 13/57 [23%], P = .01), and a lower OS (5-year OS probability 38% [95% CI 23%-53%] vs. 87% [82%-92%%], P < .001). In conclusion, refractoriness to ICT was seen in 15% of patients and was predicted by high-FLIPI scores, B symptoms, and elevated serum β2-micrglobulin. Immunochemotherapy-refractory patients had a worse prognosis than ICT-sensitive patients, and current treatment options for this subgroup are not satisfactory.

Esophageal stents are commonly used to treat benign esophageal conditions including refractory benign esophageal strictures, anastomotic strictures, fistulae, perforations and anastomotic leaks. Data on outcomes in these settings remain limited. We performed a retrospective multicenter study of patients who underwent fully or partially covered self-expandable stent placement for benign esophageal diseases. Esophageal stent placements were performed for the following indications: (1) benign refractory esophageal strictures, (2) surgical anastomotic strictures, (3) esophageal perforations, (4) esophageal fistulae, and (5) surgical anastomotic leaks. A total of 70 patients underwent esophageal stent placement for benign esophageal conditions. A total of 114 separate procedures were performed. The most common indication for esophageal stent placement was refractory benign esophageal stricture (48.2%). Global treatment success rate was 55.7%. Treatment success rate was 33.3% in refractory benign strictures, 23.1% in anastomotic strictures, 100% in perforations, 71.4% in fistulae, and 80% in anastomotic leaks. Stent migration was noted in 28 of 70 patients (40%), most commonly seen in refractory benign strictures. This is one of the largest studies to date of esophageal stents to treat benign esophageal diseases. Success rates are lowest in benign esophageal strictures. These patients have few other options beyond chronic dilations, feeding tubes, and surgery, and fully covered self-expandable metallic stent give patients a chance to have their problem fixed endoscopically and still eat by mouth. Perforations, fistulas, and leaks respond very well to esophageal stenting, and stenting should be considered as a first-line therapy in these settings.

There is an increasing trend towards using glaucoma drainage implants. The postoperative management of such devices depends on their technical characteristics and specific complications. The Baerveldt glaucoma implant with its larger surface area has been shown to lower mean intraocular pressure more effectively than the Ahmed-FP7 implant. As a non-valve implant, however, it has been associated with a higher rate of severe complications, particularly ocular hypotension. Moreover, glaucoma implants may induce diplopia if they interfere with extraocular muscles. Topical treatment with antibiotics and steroids is necessary in cases of intraocular inflammation. In refractory cases, the tube may even have to be removed. Surgical reposition of the tube may be indicated when it is severely dislocated. Increased intraocular pressure is primarily treated by pressure-lowering medications during postoperative follow-up. If topical glaucoma medication is insufficient to control increases in intraocular pressure due to encapsulation, a second implant may be considered or the capsule surrounding the implant may be excised to reduce outflow resistance or additional cyclodestructive procedures can be performed. Chronic hypotension may be treated with tube ligation or occlusion. Severe corneal oedema may require lamellar keratoplasty. Conjunctival erosions with tube exposure or tube retractions also require surgical correction. Georg Thieme Verlag KG Stuttgart · New York.

When should temporal-lobe epilepsy be treated surgically?

PubMed

Spencer, Susan S

2002-10-01

Our current knowledge of mesial-temporal-lobe epilepsy (MTLE) is extensive, yet still insufficient to draw final conclusions on the optimal approach to its therapy. MTLE has been well characterised and can usually be identified with noninvasive studies including scalp electroencephalography (EEG) and video monitoring with ictal recording, magnetic resonance imaging, single-photon-emission computed tomography, positron emission tomography, neuropsychological assessment, and historical and clinical data. Sometimes, invasive EEG is needed to confirm mesial-temporal-lobe seizure onset, which, combined with the underlying pathological abnormality (the substrate) of mesial temporal sclerosis (hippocampal neuronal loss and gliosis), defines MTLE. This disorder is the most common refractory partial epilepsy, and also the one most often treated surgically, because medical treatment fails in 75% of cases, and surgical treatment succeeds in a similar percentage. Despite the recent publication of the first randomised trial of surgical treatment for MTLE, questions remain about the neurological consequences of both medical and surgical treatment, the ultimate gains in quality of life parameters, and the precise predictors of success. Long-term follow-up and analyses of multiple factors in large groups of contemporary patient populations will be necessary to fully answer the question, "is temporal lobe epilepsy a surgical disease?" Right now it should be considered one in most cases.

Churg-Strauss syndrome (CSS) is a rare multi-system vasculitis; some cases have been reported in Korea. The aim of this study is to describe the clinical features, treatment outcome, and long-term follow-up of CSS from a single Korean medical center. Between 1995 and 2004, seventeen patients were diagnosed with CSS at the Department of Medicine of the Samsung Medical Center, Sungkyunkwan University School of Medicine. The diagnosis of CSS is based on the classification criteria of the American Collage of Rheumatology. All patients had asthma. As in other case series, the lung, peripheral nervous system, and skin were the most commonly involved organs. During the active stage of the disease, most of the patients exhibited peripheral blood eosinophilia and an elevated serum eosinophil cationic protein level. Ten patients were treated with pulses of methylprednisolone followed by tapering and cyclophosphamide, and the others were treated with corticosteroids alone. The outcomes after long-term follow-up were generally good. One patient who was refractory to initial treatment died of heart failure during the follow-up period. CSS was highly variable in its presentation and course. The manifestations may range from mild symptoms to life-threatening conditions. The outcome after long-term follow-up was as good as that of previous studies. PMID:16614512

Introduction Uveitis, a leading cause of preventable blindness around the world, is a critically underserved disease in regard to the medications approved for use. Multiple immunomodulatory therapy (IMT) drugs are appropriate for uveitis therapy but are still off-label. These IMT agents, including antimetabolites, calcineurin inhibitors, alkylating agents, and biologic agents, have been designated as “orphan drugs” and are widely used for systemic autoimmune diseases or organ transplantation. Area covered The purpose of this paper is to comprehensively review and summarize the approved orphan drugs and biologics that are being used to treat systemic diseases and to discuss drugs that have not yet received approval as an “orphan drug for treating uveitis” by the US Food and Drug Administration (FDA). Our perspective IMT, as a steroid-sparing agent for uveitis patients, has shown promising clinical results. Refractory and recurrent uveitis requires combination IMT agents. IMT is continued for a period of 2 years while the patient is in remission before considering tapering medication. Our current goals include developing further assessments regarding the efficacy, optimal dose, and safety in efforts to achieve FDA approval for “on-label” use of current IMT agents and biologics more quickly and to facilitate insurance coverage and expand access to the products for this orphan disease.

In European multicenter study, we aimed to describe the real-life hydroxychloroquine use in APS patients during pregnancy and determine its benefit in refractory obstetrical APS. We analyzed the outcome of pregnancies treated by hydroxychloroquine in patients with APS or asymptomatic antiphospholipid (aPL) antibodies carriers. Thirty patients with APS with 35 pregnancies treated by hydroxychloroquine were analyzed. Comparing the outcome of pregnancies treated by the addition of hydroxychloroquine to previous pregnancies under the conventional treatment, pregnancy losses decreased from 81% to 19% (p<0.05), without differences in the associated treatments. The univariate analysis showed that the previous intrauterine deaths and higher hydroxychloroquine amount (400mg per day) were the factors associated with pregnancy outcome. Considering 14 patients with previous refractory obstetrical APS (n=5 with obstetrical and thrombotic primary APS and n=9 with purely obstetrical APS), all with previous pregnancy losses under treatment (aspirin with LMWH in 11 cases and LMWH in 3 cases), the addition of hydroxychloroquine resulted in live born babies in 11/14 (78%) cases (p<0.05). Our study shows the benefit of hydroxychloroquine addition in patients with refractory obstetrical APS and raises the need of prospective studies to confirm our preliminary study.

Electroconvulsive therapy, a standard treatment in mood disorders, is sometimes also indicated in psychotic disorders, especially in the treatment of refractory schizophrenia. In this instance, maintenance electroconvulsive therapy (M-ECT) can also become a long-term treatment. This paper presents the effects of M-ECT in the treatment of refractory schizophrenia using a retrospective analysis. Previous works showed that electroconvulsive therapy is effective on catatonia, anxiety with somatisation, lack of compliance, opposition, delusions especially with hallucinations and persecution, anorexia, agitation, carelessness, aggressive behaviour and moral pain. It is ineffective on bewilderment, somatic complaints and negative symptoms. A retrospective analysis of a clinical cohort of patients treated with M-ECT was carried out to determine the specific indications of M-ECT, its effectiveness on clinical symptoms, quality of life, relapse rates and use of medication. Nineteen patients with DSM-IV diagnosis of paranoid schizophrenia (n=5), schizophrenia with neurotic symptoms (n=3), disorganized schizophrenia (n=1), hebephrenia (n=3) and schizoaffective disorder (n=8), treated in the department of the University Hospital of Sainte-Anne in Paris, received M-ECT between 1991 and 2005. Seven patients are still under this treatment. Their mean age at the beginning of treatment was 47.5 years with a mean duration of the illness of 24 years. The indication of M-ECT was the increase of acute episodes, an increase of symptoms intensity, the inefficiency or intolerance to pharmacological treatments or an early relapse after ECT discontinuation. All patients had previously been successfully treated by ECT during an acute episode. Each patient received an average of 47 bilateral M-ECT under general anaesthesia at one to five weeks' intervals for a mean period of 43 months. All of them were also treated by antipsychotics; in addition, 30% received mood stabilizers and 10% antidepressants. The dosage of antidepressants and mood stabilizers was reduced during M-ECT treatment, especially in patients with schizoaffective disorder, probably in relation with the effectiveness of ECT on mood symptoms. During M-ECT, the mean duration of yearly hospitalizations was decreased by 80% and the mean duration of each hospitalization by 40% with a better ability to take part in activities, sometimes even to return home or go back to work. There was also a positive effect on quality of life considering the severity of symptoms and the long psychiatric history of these patients. The possibility to go from a full time hospitalization to a day-care facility or to live in a halfway house can be considered as a huge progress. M-ECT was efficient on mood symptoms, delusions, anorexia, suicidal impetus, anxiety symptoms and increased cooperation and treatment compliance. Efficacy on obsessive compulsive symptoms was less obvious. There was no effect on dissociation and negative symptoms. Relapses essentially occurred after a stressful life event, a too long interval between the M-ECT sessions or, in 50% of the cases, without any obvious etiology. It required a revision of the M-ECT program and, most of the time, an hospitalization for full ECT treatment. There is no consensus on the rate and number of M-ECT as it varies from patient to patient and depends upon the extent of the clinical response and side effects. The discontinuation of M-ECT will depend on the clinical symptoms, compliance and tolerance to ECT. As it is the case with ECT treatment for an acute episode, available evidence suggests that treatment with antipsychotics should continue during the maintenance ECT course. Maintenance electroconvulsive therapy combined with medication may be an efficient alternative to pharmacological treatment alone in refractory schizophrenia. Alternative therapeutical strategies are crucial in this domain, due to the important public health problem it raises. There are few randomised prospective controlled clinical trials regarding this treatment and further clinical investigations are necessary, notably to define standardized criteria for M-ECT programs.

Introduction: Myasthenia gravis (MG) is an antibody mediated autoimmune neuromuscular disorder characterized by fatigable muscle weakness. A proportion of myasthenia gravis patients are classified as refractory due to non responsiveness to conventional treatment. This retrospective study was done to evaluate clinical profile, epidemiological, laboratory, and features of patients with MG and mode of management using rituximab and complications. Methods: Data of myasthenia gravis patients admitted or presented to outpatient department (previous medical records) with MG between January 2008 and January 2016 were included. A total of 512 patients fulfilled the clinical and diagnostic criteria of myasthenia gravis of which 76 patients met the diagnostic certainty for refractory myasthenia gravis and were evaluated. Results: Out of 76 refractory MG patients, 53 (69.73%) patients fulfilled all the three defined criteria. The median age of onset of the refractory MG group was 36 years with a range of 27-53 years. In our study 25 patients (32.89%) belonged to the age group of 21-30 years. Anti-MuSK antibodies were positive in 8 non-refractory MG patients (2.06%) and 36 refractory MG patients (47.36%). Mean HbA 1C was found to be 8.6±2.33. The dose of administered prednisone decreased by a mean of 59.7% ( p =3.3x10 -8 ) to 94.6% ( p =2.2x10 -14 ) after the third cycle of rituximab treatment. Conclusion: The refractory MG patients are most commonly female with an early age of onset, anti-MuSK antibodies, and thymomas. Refractory MG patients have higher prevalence and poor control (HbA 1C >8%) of diabetes mellitus and dyslipidemia probably due to increased steroid usage. Rituximab is very efficient in treatment of refractory MG with adverse effects being low.

The mixed lineage leukaemia (MLL) gene translocations are found in approximately 10% of adults with acute myeloid leukaemia (AML) and are markers of poor prognosis. As the best reported response in relapsed and refractory MLL-rearranged AML is around 40%, reinduction treatment is very challenging for those patients. We report a case of relapsed and refractory AML with MLL-AF9, who did not respond to FLAG (fludarabine, cytarabine, granulocyte colony stimulating factor) regimen reinduction treatment, but achieved complete response and molecular remission after chidamide-based chemotherapy. Chidamide (CS055/HBI-8000) is a new histone deacetylase (HDAC) inhibitor that is clinically active in relapsed and refractory peripheral T-cell lymphomas. To the best of our knowledge, successful reinduction treatment on relapsed MLL-AF9 by chidamide-based regimen has not been previously reported. © 2017 John Wiley & Sons Ltd.

Eight non-splenectomized patients with corticosteroid-refractory idiopathic thrombocytopenic purpura (ITP) were treated with low-dose vincristine (1 mg/week up to a total dose of 4 mg). Complete remission was achieved in 2 cases and partial remission in 3. Bleeding stopped in one patient who failed to remit. No statistical relationship was found between the response to vincristine and the duration of the disease or the corticosteroid-therapy. Side effects were only observed in one patient. By comparing these results with those reported in the literature, it can be inferred that low-dose vincristine may be useful in the management of corticosteroid-refractory ITP. PMID:7194478

Mitoguazone is a unique antitumor agent that interferes with polyamine synthesis that has been reported to have activity against AIDS-related malignant lymphoma. We, therefore, tested this agent for activity against chronic lymphocytic leukemia (CLL) in this phase II study. Mitoguazone, 500 mg/M2 was given intravenously weekly to 13 patients with relapsed or refractory, previously treated Rai stages 2-4 CLL. There were no complete or partial responses as judged by standard criteria. Toxicity was acceptable. Mitoguazone in the dose and schedule employed in this study has no significant activity as a single agent in patients with relapsed or refractory CLL.

Steroid-refractory graft-versus-host disease is a life-threatening complication after allogeneic stem cell transplantation. Evidence is accumulating that steroid-refractory graft-versus-host disease is associated with endothelial distress. Endothelial cell homeostasis is regulated by nitric oxide, and serum nitrates are derived from nitric oxide synthase activity or dietary sources. In this retrospective study based on 417 patients allografted at our institution we investigated whether quantification of serum nitrates could predict steroid-refractory graft-versus-host disease. Elevated pre-transplant levels of serum nitrates (>26.5 μM) predicted steroid-refractory graft-versus-host disease (P=0.026) and non-relapse mortality (P=0.028), particularly in combination with high pre-transplant angiopoietin-2 levels (P=0.0007 and P=0.021, respectively). Multivariate analyses confirmed serum nitrates as independent predictors of steroid-refractory graft-versus-host disease and non-relapse mortality. Differences in serum nitrate levels did not correlate with serum levels of tumor necrosis factor or C-reactive protein or expression of inducible nitric oxide synthase in blood cells. Patients with high pre-transplant nitrate levels had significantly reduced rates of refractory graft-versus-host disease (P=0.031) when pravastatin was taken. In summary, patients at high risk of developing steroid-refractory graft-versus-host disease could be identified prior to transplantation by serum markers linked to endothelial cell function. Retrospectively, statin medication was associated with a reduced incidence of refractory graft-versus-host disease in this endothelial high-risk cohort. PMID:24142995

Sepsis is the most common cause of death in medical intensive care units (ICU). If sepsis progresses to refractory septic shock, mortality may reach 90-100% despite optimum current therapy. Extracorporeal cytokine adsorption in addition to regular therapy was studied prospectively in refractory septic shock patients on a medical ICU. Refractory shock was defined as increasing vasopressor dose required to maintain mean arterial blood pressure above 65 mmHg or increasing lactate levels despite protocol-guided shock therapy for 6 h. We analysed noradrenaline requirements after 6 and 12 h (primary endpoint), lactate clearance after 6 and 12 h, SOFA-scores in the first days and achievement of shock reversal (i.e., normalization of lactate concentrations and sustained discontinuation of vasopressors; secondary endpoints). Twenty consecutive patients with refractory septic shock were included; CytoSorb ® treatment was started after 7.8 ± 3.7 h of shock therapy. Following the initiation of adsorption therapy, noradrenaline dose could be significantly reduced after 6 (-0.4 µg/kg/min; p = 0.03) and 12 h (-0.6 µg/kg/min; p = 0.001). Lactate clearance improved significantly. SOFA-scores on day 0, 1 and 2 remained unchanged. Shock reversal was achieved in 13 (65%) patients; 28-day survival was 45%. In severe septic shock unresponsive to standard treatment, haemodynamic stabilization was achieved using cytokine adsorption therapy, resulting in shock reversal in two-thirds of these patients. The study was registered in the German Register for Clinical Trials (DRKS) No. 00005149.

To report the feasibility, complications, and outcomes of emergency extracorporeal life support (ECLS) in refractory cardiac arrests in medical intensive care unit (ICU). Prospective cohort study in the medical ICU in a university hospital in collaboration with the cardiosurgical team of a neighboring hospital. Seventeen patients (poisonings: 12/17) admitted over a 2-year period for cardiac arrest unresponsive to cardiopulmonary resuscitation (CPR) and advanced cardiac life support, without return of spontaneous circulation. ECLS femoral implantation under continuous cardiac massage, using a centrifugal pump connected to a hollow-fiber membrane oxygenator. Stable ECLS was achieved in 14 of 17 patients. Early complications included massive transfusions (n=8) and the need for surgical revision at the cannulation site for bleeding (n=1). Four patients (24%) survived at medical ICU discharge. Deaths resulted from multiorgan failure (n=8), thoracic bleeding(n=2), severe sepsis (n=2), and brain death (n=1). Massive hemorrhagic pulmonary edema during CPR (n=5) and major capillary leak syndrome (n=6) were observed. Three cardiotoxic-poisoned patients (18%, CPR duration: 30, 100, and 180 min) were alive at 1-year follow-up without sequelae. Two of these patients survived despite elevated plasma lactate concentrations before cannulation (39.0 and 20.0 mmol/l). ECLS was associated with a significantly lower ICU mortality rate than that expected from the Simplified Acute Physiology Score II (91.9%) and lower than the maximum Sequential Organ Failure Assessment score (>90%). Emergency ECLS is feasible in medical ICU and should be considered as a resuscitative tool for selected patients suffering from refractory cardiac arrest.

Sacroiliac joint syndrome (SIJ) is diagnosed in 10% to 25% of cases of lower back pain. The response to traditional radiofrequency (RF) denervation of the SIJ has being inconsistent. The Simplicity III RF probe (Neruotherm. Inc.) offers a novel treatment option. To evaluate the long-term clinical outcome (12 months) refractory SIJ syndrome in terms of pain intensity and functional improvement. A 50% reduction in intensity pain intensity (VAS) at 12 months was deemed clinically significant. A 12-month retrospective observational evaluation all of adults treated with RF for refractory SIJ. Chronic pain management center. The medical records of all adults treated with this technique was retrospectively reviewed. The primary outcome was pain intensity scores (VAS) over a 12 months period; Secondary outcomes included Roland-Morris Functional scores (RMF), Brief Pain Inventory (BPI), general health assessment (Sf12), and patient satisfaction scores (GPI), which were recorded pre and post denervation. Pain Intensity improved by 4.7 points compared to pre-treatment representing a 61% reduction in pain at 12 months (n=11, P < 0.001). Significant improvements in (a) RMF (P < 0.01, W2 = 0.63 (large effect size); (b) BPI (P < 0.001, W2 = 0.72 (strong effect size); and (c) Sf12 (P < 0.01) were noted. Overall patients were satisfied with the outcome (GPI = 77.7%). The retrospective in nature of the study and the small sample size are limitations. As it was our policy to monitor the progress of the individuals since the introduction of this technique a reliable method of recording the baseline and outcome variables at each point of contact was in place. Access to a complete set of variables in all individuals over a 12-month period was therefore possible, which we feel contributes to the quality of the dataset. By creating a consistent radiofrequency lesion between the sacral foramen and the SIJ will reliably capture the innervation to the SIJ with significant long-term clinical improvement. This technique should be considered earlier in the treatment algorithm of individuals suffering from SIJ symptoms.

The Pharmacological Basis of Cannabis Therapy for Epilepsy.

PubMed

Reddy, Doodipala Samba; Golub, Victoria M

2016-04-01

Recently, cannabis has been suggested as a potential alternative therapy for refractory epilepsy, which affects 30% of epilepsy, both adults and children, who do not respond to current medications. There is a large unmet medical need for new antiepileptics that would not interfere with normal function in patients with refractory epilepsy and conditions associated with refractory seizures. The two chief cannabinoids are Δ-9-tetrahyrdrocannabinol, the major psychoactive component of marijuana, and cannabidiol (CBD), the major nonpsychoactive component of marijuana. Claims of clinical efficacy in epilepsy of CBD-predominant cannabis or medical marijuana come mostly from limited studies, surveys, or case reports. However, the mechanisms underlying the antiepileptic efficacy of cannabis remain unclear. This article highlights the pharmacological basis of cannabis therapy, with an emphasis on the endocannabinoid mechanisms underlying the emerging neurotherapeutics of CBD in epilepsy. CBD is anticonvulsant, but it has a low affinity for the cannabinoid receptors CB1 and CB2; therefore the exact mechanism by which it affects seizures remains poorly understood. A rigorous clinical evaluation of pharmaceutical CBD products is needed to establish the safety and efficacy of their use in the treatment of epilepsy. Identification of mechanisms underlying the anticonvulsant efficacy of CBD is also critical for identifying other potential treatment options.

No evidence can be found in the medical literature about the efficacy of alternating acetaminophen and ibuprofen treatment in children with refractory fever. Our objective was to assess the effect of alternating acetaminophen and ibuprofen therapy on distress and refractory fever compared with acetaminophen or ibuprofen as monotherapy in febrile children. A total of 474 febrile children with axillary temperature ≥38.5 °C and fever history ≤3 days in a tertiary hospital were randomly assigned to receive either (1) alternating acetaminophen and ibuprofen (acetaminophen 10 mg/kg per dose with shortest interval of 4 h and ibuprofen 10 mg/kg per dose with shortest interval of 6 h and the shortest interval between acetaminophen and ibuprofen ≥2 h; n = 158), (2) acetaminophen monotherapy (10 mg/kg per dose with shortest interval of 4 h; n = 158), or (3) ibuprofen monotherapy (10 mg/kg per dose with shortest interval of 6 h; n = 158). The mean Non-Communicating Children's Pain Checklist (NCCPC) score was measured every 4 h, and axillary temperatures were measured every 2 h. In total, 471 children were included in an intention-to-treat analysis. No significant clinical or statistical difference was found in mean NCCPC score or temperature during the 24-h treatment period in all febrile children across the three groups. Although the proportion of children with refractory fever for 4 h and 6 h was significantly lower in the alternating group than in the monotherapy groups (4 h: 11.54% vs. 26.58% vs. 21.66%, respectively [p = 0.003]; 6 h: 3.85% vs. 10.13% vs. 17.83%, respectively [p < 0.001]), the mean NCCPC score of children with refractory fever for 4 or 6 h was not lower than those in either of the monotherapy groups. The number of patients who developed persistent high body temperature was consistent across all study groups. Alternating acetaminophen and ibuprofen can reduce the proportion of children with refractory fever, but if one cycle of alternating therapy cannot reduce febrile distress as defined by NCCPC score, two or more cycles of alternating therapy may have minimal to no clinical efficacy in some cases. The trial was registered with the Chinese Clinical Trial Registry as ChiCTR-TRC-13003440 and the WHO Registry Network as U1111-1146-6714.

Few reports are available on the characteristics of electrical storms of ventricular tachycardia (VT storm) refractory to intravenous (IV) amiodarone. IV-amiodarone was administered to 60 patients with ventricular tachyarrhythmia between 2007 and 2012. VT storms, defined as 3 or more episodes of VT within 24 h, occurred in 30 patients (68±12 years, 7 female), with 12 having ischemic and 18 non-ischemic heart disease. We compared the clinical and electrocardiographic characteristics of the patients with VT storms suppressed by IV-amiodarone (Effective group) to those of patients not affected by the treatment (Refractory group). IV-amiodarone could not control recurrence of VT in 9 patients (30%). The Refractory group comprised 5 patients with acute myocardial infarctions. Although there was no difference in the VT cycle length, the QRS duration of both the VT and premature ventricular contractions (PVCs) followed by VT was narrower in the Refractory group than in the Effective group (140±30 vs. 178±25 ms, P<0.01; 121±14 vs. 179±22 ms, P<0.01). In the Refractory group, additional administration of IV-mexiletine and/or Purkinje potential-guided catheter ablation was effective. IV-amiodarone-refractory VT exhibited a relatively narrow QRS tachycardia. The narrow triggering PVCs, suggesting a Purkinje fiber origin, may be treated by additional IV-mexiletine and endocardial catheter ablation.

Canine demodicosis is a refractory skin disease caused by excessive proliferation of mite Demodex canis. Despite availability of several treatment options, the disease poses a great challenge to clinicians for its long term management as some drugs may be ineffective or toxic. Present report describes successful treatment of two refractory cases of canine demodicosis using homeopathy medicine. After oral administration of Graphitis 200 C two drops once daily for 2 months, complete cure from the disease was observed. No adverse health effects of the medication were recorded during the treatment. Thus, it may be concluded that homeopathy medicine may be used safely for long-term management of canine demodicosis.

Use of Serum Infliximab Level Prior to Cyclosporine Salvage Therapy in Severe Ulcerative Colitis

2014-01-01

Medical treatment options for severe, steroid refractory ulcerative colitis (UC) include infliximab (IFX) or cyclosporine (CSA), but general consensus has been that both agents should not be used together or even successively. We report a case of a 17-year-old male with severe UC refractory to IV steroids with successful sequential salvage therapy guided by serum IFX level. After primary lack of response to IFX, an undetectable serum IFX level and elevated IFX antibodies were followed by immediate transition to IV CSA. This case demonstrates the possibility of therapeutic drug monitoring of IFX levels when calculating the risk/benefit ratio for patients with steroid-refractory UC failing primary salvage therapy.

Refractory dyspareunia presents a challenging therapeutic dilemma. A woman with defecatory dysfunction and dyspareunia presented with stage 2 prolapse. She underwent laparoscopic and vaginal pelvic floor reconstruction with excision of endometriosis. The patient experienced increased dyspareunia and de novo vaginismus postoperatively that were refractory to trigger point injections, physical therapy, and medical and surgical management. She underwent botulinum toxin type A injections into her levator ani muscles, which allowed her to have sexual intercourse again after 2 years of apareunia with no recurrence of pain for 12 months. Injecting botulinum toxin into the levator ani muscles shows promise for postoperative patients who develop vaginismus and do not respond to conservative therapy.

Hepatic encephalopathy is considered a contraindication to hepatic artery embolization. We describe a patient with a well-differentiated neuroendocrine tumor metastatic to the liver with refractory hepatic encephalopathy and normal liver function tests. The encephalopathy was refractory to standard medical therapy with lactulose. The patient's mental status returned to baseline after three hepatic artery embolization procedures. Arteriography and ultrasound imaging before and after embolization suggest that the encephalopathy was due to arterioportal shunting causing hepatofugal portal venous flow and portosystemic shunting. In patients with a primary or metastatic well-differentiated neuroendocrine tumor whose refractory hepatic encephalopathy is due to portosystemic shunting (rathermore » than global hepatic dysfunction secondary to tumor burden), hepatic artery embolization can be performed safely and effectively.« less

OBJECTIVE Anterior capsulotomy (AC) is sometimes used as a last resort for treatment-refractory obsessive-compulsive disorder (OCD). Previous studies assessing neuropsychological outcomes in patients with OCD have identified several forms of cognitive dysfunction that are associated with the disease, but few have focused on changes in cognitive function in OCD patients who have undergone surgery. In the present study, the authors investigated the effects of AC on the cognitive function of patients with treatment-refractory OCD. METHODS The authors selected 14 patients with treatment-refractory OCD who had undergone bilateral AC between 2007 and 2013, 14 nonsurgically treated OCD patients, and 14 healthy control subjects for this study. The 3 groups were matched for sex, age, and education. Several neuropsychological tests, including Similarities and Block Design, which are subsets of the Wechsler Abbreviated Scale of Intelligence; Immediate and Delayed Logical Memory and Immediate and Delayed Visual Reproduction, which are subsets of the Wechsler Memory Scale-Revised; and Corrects, Categories, Perseverative Errors, Nonperseverative Errors, and Errors, subtests of the Wisconsin Card Sorting Test, were conducted in all 42 subjects at baseline and after AC, after nonsurgical treatment, or at 6-month intervals, as appropriate. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was used to measure OCD symptoms in all 28 OCD patients. RESULTS The Y-BOCS scores decreased significantly in both OCD groups during the 12-month follow-up period. Surgical patients showed higher levels of improvement in verbal memory, visual memory, visuospatial skills, and executive function than the nonsurgically treated OCD patients. CONCLUSIONS The findings of this study suggest that AC not only reduces OCD symptoms but also attenuates moderate cognitive deficits.

To evaluate the effect of twice daily aqueous 0.02% sirolimus drops on tear production in normal dogs and dogs with refractory keratoconjunctivitis sicca (KCS). Two groups of dogs were studied. Ten normal dogs with no signs of ocular disease were administered topical 0.02% sirolimus ophthalmic solution in right eye, and a vehicle control in the left eye twice daily for 4 weeks. Complete ophthalmic examinations, including Schirmer tear test were performed weekly. Eighteen dogs with refractory KCS were randomly assigned to receive 0.02% sirolumus ophthalmic solution or 0.02% tacrolimus ophthalmic solution twice daily. Complete ophthalmic examinations were was performed at 2 and 6 weeks following treatment. Tear production in the sirolimus-treated eyes of normal dogs was greater when compared to vehicle controls with a mean difference over all time points of 3.46 mm (95% CI 1.17, 5.75; P = 0.006). After 4 weeks of treatment, the mean difference was 5 mm (95% CI 1.95, 8.05; P = 0.002). In dogs with refractory dry eye, 37.5% of eyes treated with sirolimus exhibited increased tear production >4 mm/min after 6 weeks of treatment, compared to 20% of eyes receiving tacrolimus (P = 0.433). One normal dog experienced topical irritation to both sirolimus and vehicle-treatment. Side effects were not reported in any treated eyes with chronic KCS. Topical 0.02% sirolimus might be an alternative treatment for canine patients with keratoconjunctivits sicca. The drug appears safe when applied topically in an aqueous suspension for up to 6 weeks. While initial results are promising, further studies are warranted. © 2017 American College of Veterinary Ophthalmologists.

Traditional Chinese Medicine for Refractory Nephrotic Syndrome: Strategies and Promising Treatments

PubMed Central

Tu, Yuan-Chao

2018-01-01

Refractory nephrotic syndrome (RNS) is an immune-related kidney disease with poor clinical outcomes. Standard treatments include corticosteroids as the initial therapy and other immunosuppressants as second-line options. A substantial proportion of patients with RNS are resistant to or dependent on immunosuppressive drugs and often experience unremitting edema and proteinuria, cycles of remission and relapse, and/or serious adverse events due to long-term immunosuppression. Traditional Chinese medicine has a long history of treating complicated kidney diseases and holds great potential for providing effective treatments for RNS. This review describes the Chinese medical theories relating to the pathogenesis of RNS and discusses the strategies and treatment options using Chinese herbal medicine. Available preclinical and clinical evidence strongly supports the integration of traditional Chinese medicine and Western medicine for improving the outcome of RNS. Herbal medicine such as Astragalus membranaceus, Stephania tetrandra S. Moore, and Tripterygium wilfordii Hook F can serve as the alternative therapy when patients fail to respond to immunosuppression or as the complementary therapy to improve therapeutic efficacy and reduce side effects of immunosuppressive agents. Wuzhi capsules (Schisandra sphenanthera extract) with tacrolimus and tetrandrine with corticosteroids are two herb-drug combinations that have shown great promise and warrant further studies.

Ischemic colitis related to sumatriptan overuse.

PubMed

Hodge, Joshua A; Hodge, Katherine D

2010-01-01

Serotonin-1 5-hydroxytryptamine (5-HT 1) receptor agonists are first line agents for migraine headaches. Patients with refractory headaches may use supratherapeutic doses of these medications. Described is a case of ischemic colitis related to overuse of sumatriptan. A 35-year-old woman presented with severe abdominal pain without diarrhea or hematochezia. For several days prior she had been self-treating a refractory migraine headache with frequent doses of sumatriptan. She is a nonsmoker and took no oral contraceptives or other serotonin agonists. A computed tomography scan of the abdomen revealed left-sided colitis. A colonoscopy with biopsy confirmed ischemic colitis and excluded inflammatory bowel disease (IBD). Previously published case reports have suggested an association between 5-HT 1 receptor agonists and ischemic colitis. These reports have been dismissed because the patients were taking oral contraceptives, serotonin agonists, or had other comorbidities. This healthy patient lacked risk factors for ischemia, is the youngest to be reported, and is the first without hematochezia. 5-HT 1 receptor agonists are generally considered safe. Ischemic colitis is a potentially serious complication of these agents. A retrospective review of 5-HT 1 receptor agonist users who have presented with acute onset abdominal pain or hematochezia is necessary to elucidate the incidence of this adverse event.

To evaluate the electroclinical features of epilepsy secondary to neonatal hypoglycaemia. This was a retrospective study of children who had seizures beyond infancy after neonatal hypoglycaemia treated at The Royal Children's Hospital, Melbourne between 1996 and 2012. Patients with perinatal asphyxia were excluded. Clinical details were obtained from medical records. Digital electroencephalography (EEG) and brain magnetic resonance imaging (MRI) were reviewed. Eleven patients met the inclusion criteria (six males, five females; mean age 10y 5mo, range 4-18y at the time of review). Age at seizure onset ranged from 4 months to 5 years. Seizures were focal occipital in nine and generalized tonic in two patients. MRI showed gliosis with or without cortical atrophy in the occipital lobe with or without parietal lobe in all. Predominant EEG findings were stereotyped occipital sharp-slow discharges in five, polymorphic occipital spike-wave or paroxysmal fast activity in three, and generalized slow spike-wave and fast activity in two. Seizures were infrequent or remitted in six of the nine children with focal occipital seizures, and frequent and refractory in both children with generalized seizures. Despite the common antecedent and bilateral occipital lobe injury, the seizure manifestations and course of epilepsy after neonatal hypoglycaemia were variable, with mild occipital, refractory occipital, and symptomatic generalized epilepsy recognized. © 2014 Mac Keith Press.

High Voltage Pulsed Radiofrequency for the Treatment of Refractory Neuralgia of the Infraorbital Nerve: A Prospective Double-Blinded Randomized Controlled Study.

A recent study showed that 50% of patients who suffered from refractory neuralgia of the infraorbital nerve obtained satisfactory efficacy after pulsed radiofrequency (PRF) treatment. A pilot study showed that increasing the output voltage of PRF significantly improved the efficacy for trigeminal neuralgia; however, whether increasing the output voltage of PRF can improve the treatment outcomes for neuralgia of the infraorbital nerve is unknown. To evaluate the efficacy and safety of high voltage PRF treatment in comparison with standard voltage PRF for neuralgia of the infraorbital nerve. Prospective, single-center, double-blinded, randomized, controlled trial. Beijing Tiantan Hospital, Capital Medical University. A total of 60 patients with refractory neuralgia of the infraorbital nerve were randomly divided into the high voltage PRF group and the standard voltage PRF group to treat their infraorbital nerves. Neither the patients, pain physicians, nor the follow-up evaluators knew the patient group assignments. The primary outcome measure was the one-year response rate. The secondary outcome measures included the time to take effect after PRF, the one-month, 3-month, and 6-month response rates, the relapse rate, and adverse reactions. The intent-to-treat analysis showed that the one-month, 3-month, 6-month, and one-year response rates were all 90% in the high voltage group, which were significantly higher than the rates in the standard voltage group (67% [P < 0.05], 67% [P < 0.05], 63% [P < 0.05], and 60% [P <0.01], respectively). Furthermore, 27% of the patients in the high-voltage group and 13% of the patients in the standard voltage group experienced minor transient (10 - 30 days) numbness in the innervation area after PRF; no other serious adverse reactions were observed in the 2 groups (P > 0.05). We did not investigate the dose-effect relationship between the output voltage and efficacy or the effect of a higher pulse dose on efficacy. This study was a single-center study, and multi-center, randomized, controlled studies are needed to obtain the highest level of empirical evidence. Additionally, the follow-up period lasted only one year in this study; thus, long-term efficacy needs to be further confirmed. The results showed that high voltage PRF was effective and safe for patients with refractory neuralgia of the infraorbital nerve and could become a treatment option in patients who do not respond to conservative treatment.

Cardiac resynchronisation therapy in the presence of left-to-right intracardiac shunting: more good than harm?

An elderly Chinese man with moderately impaired left ventricular function, left bundle branch block and ST-elevation myocardial infarction complicated by ventricular septal rupture had class IV heart failure symptoms refractory to medical and surgical interventions. As a treatment of last resort, a cardiac resynchronisation therapy (CRT) pacemaker was implanted apprehensively, as preoperative concerns were raised whether CRT could exacerbate left-to-right shunting, hence negating the potential benefits of CRT. Introduction of CRT significantly improved the patient's haemodynamic status and symptoms, allowing for successful discharge home. To the best of our knowledge, this is the first report of a patient with severely symptomatic acute heart failure, widened QRS and active left-to-right intracardiac shunting, treated successfully with CRT. 2016 BMJ Publishing Group Ltd.

Patients with refractory severe hypertriglyceridemia are at risk of pancreatitis and cardiovascular disease. The role of individualized nutrition therapy in these patients independent of pharmaceutical treatment has not been documented. To document the effect of nutrition intervention on severe hypertriglyceridemia regardless of medication status or prior nutrition counseling. Outcomes of new patients with triglycerides ≥ 500 mg/dL presenting to a Lipid Management Program over a 6-year period were tracked. Patients received comprehensive laboratory assessment, nutrition assessment, and initiation of an individualized diet intervention before seeing the lipidologist. Clinical and behavioral outcomes were recorded. In all, 168 patients (117 men; mean age, 49.03 ± 11.22 years; body mass index, 32.61 ± 5.85 kg/m(2); 110 (65.5%) on lipid-lowering medications) returned for assessment of nutrition intervention. Triglycerides were reduced from median (interquartile range) 961.5 (611.5-1785.3) to 493.0 (337-736.3) mg/dL (P < .0001 for log transformation of triglycerides). There was no difference in median percentage reduction in triglycerides after nutrition intervention between those not on lipid-lowering medication, on a fibric acid derivative, on other lipid-lowering medication, or on a combination of lipid-lowering medications (P = .376) in a median (interquartile range) of 5 (3-7) weeks. Effect was independent of prior nutrition counseling (P = .260). Reported percentage fat in the diet at second visit correlated with log-transformed triglycerides achieved, independent of initial triglycerides level (r = 0.290; P = .001). Individualized nutrition therapy results in changes in eating behavior and reductions in triglyceride levels in patients with refractory severe hypertriglyceridemia independent of lipid-lowering medication(s) and prior nutrition counseling.

We conducted a phase II trial to investigate the safety and efficacy of alemtuzumab in treating steroid-refractory acute graft-versus-host disease (aGVHD) grade II or higher after stem cell transplantation. Ten adult patients (6 with aGVHD grade III and 4 with aGVHD grade IV) were included in the study. Nine patients had gastrointestinal tract involvement, 7 had skin involvement, and 5 had liver involvement. Five patients responded to treatment, 2 with complete response and 3 with partial response. Eight infectious events (4 of grade 3-4) and 7 cytomegalovirus (CMV) reactivations were observed. Six patients had grade 3-4 cytopenia. All 10 patients died (7 resulting from aGVHD progression, 2 from severe infection, and 1 from to leukemia relapse), at a median of 40 days (range, 4 to 88 days) after alemtuzumab treatment. Overall, our findings suggest that steroid-refractory aGVHD may be improved by treatment with alemtuzumab, but that this treatment does not overcome the dismal prognosis of patients with severe aGVHD, demonstrating the need for alternative therapies to treat this complication.

Surface treatment of alumina-based ceramics using combined laser sources

NASA Astrophysics Data System (ADS)

2002-01-01

Alumina-based refractory materials are extensively used as linings in incinerators and furnaces. These materials are subject to molten salt corrosion and chemical degradation because of the existence of porosity and material inhomogeneity. Efforts to improve the performance of these materials have so far concentrated mainly on the optimisation of the manufacturing processes (e.g. producing denser refractory bricks) and in-service monitoring. Laser surface treatment has also been used to improve performance. The main problem identified with laser surface treatment is solidification cracking due to the generation of very large temperature gradients. The aim of this paper is to investigate the surface modification of alumina-based ceramics by using two combined laser sources in order to control the thermal gradients and cooling rates during processing so that crack formation can be eliminated. The material under investigation is 85% alumina refractory ceramic, used as lining material in incineration plants. The surface morphology and cross-section of the treated samples are analysed using optical and scanning electron microscopy (SEM) and compared with single laser beam treated samples.

Better VPS Fabrication of Crucibles and Furnace Cartridges

2003-01-01

An experimental investigation has shown that by (1) vacuum plasma spraying (VPS) of suitable refractory metal alloys on graphite mandrels, and then (2) heat-treating the VPS alloy deposits under suitable conditions, it is possible to fabricate improved crucibles and furnace cartridges that could be used at maximum temperatures between 1,400 and 1,600 C and that could withstand chemical attack by the materials to be heated in the crucibles and cartridges. Taken by itself, the basic concept of fabricating furnace cartridges by VPS of refractory materials onto graphite mandrels is not new; taken by itself, the basic concept of heat treatment of VPS deposits for use as other than furnace cartridges is also not new; however, prior to this investigation, experimental crucibles and furnace cartridges fabricated by VPS had not been heat treated and had been found to be relatively weak and brittle. Accordingly, the investigation was directed toward determining whether certain combinations of (1) refractory alloy compositions, (2) VPS parameters, and (3) heat-treatment parameters could result in VPS-fabricated components with increased ductility.

Acute encephalitis with refractory, repetitive partial seizures (AERRPS) is characterized by repetitive seizures during the acute and chronic phases and has a poor neurological outcome. Burst-suppression coma via continuous i.v. infusion of a short-acting barbiturate is used to terminate refractory seizures, but the severe side-effects of short-acting barbiturates are problematic. We report on a 9-year-old boy with AERRPS who was effectively treated with very-high-dose phenobarbital (VHDPB) combined with intermittent short-acting barbiturates. VHDPB side-effects were mild, especially compared with those associated with continuous i.v. infusion of short-acting barbiturates (dosage, 40-75 mg/kg/day; maximum blood level, 290 μg/mL). Using VHDPB as the main treatment, short-acting barbiturates were used intermittently and in small amounts. This is the first report to show that VHDPB, combined with intermittent short-acting barbiturates, can effectively treat AERRPS. After treatment, convulsions were suppressed and daily life continued, but intellectual impairment and high-level dysfunction remained. © 2016 Japan Pediatric Society.

Brentuximab vedotin in refractory CD30+ lymphomas: a bridge to allogeneic transplantation in approximately one quarter of patients treated on a Named Patient Programme at a single UK center

The CD30-targeted agent brentuximab vedotin has shown impressive activity in relapsed/refractory Hodgkin lymphoma and anaplastic large cell lymphoma in phase II studies. We have treated 24 patients with relapsed/refratory disease enrolled onto a Named Patient Programme during 2010-11 at a single UK center. Overall response rate across all histologies was 67% (Hodgkin 72%; anaplastic large cell 60%), complete response rate 25% (Hodgkin 17%; anaplastic large cell 60%), median progression-free survival 5.1 months, and toxicity mild to moderate in the majority of cases. Six patients proceeded to allogeneic transplantation and one patient awaits this procedure. These results are similar to phase II data and show that brentuximab vedotin provides a bridge to allogeneic transplantation in approximately one quarter of patients refractory to conventional salvage therapies. Best response was seen after four doses, so consideration of allogeneic transplantation should be made early and scheduled following the first assessment indicating response. PMID:23065511

Bilateral perisylvian ulegyria: an under-recognized, surgically remediable epileptic syndrome.

Interest in the association of epilepsy and pseudobulbar palsy was rekindled since the identification through magnetic resonance imaging (MRI) of bilateral perisylvian polymicrogyria (PMG). Seizures are often intractable, but resective epilepsy surgery has not been recommended. However, a similar clinical picture can be encountered in patients with bilateral perisylvian destructive lesions, which fit the description of ulegyria (ULG). We report a series of patients with epilepsy and pseudobulbar palsy due to bilateral perisylvian ULG (BP-ULG), show that hippocampal sclerosis (HS) is often associated and highlight the fact that in this entity, unlike in malformative bilateral perisylvian PMG, seizures may be surgically treated. The motor, cognitive, epileptologic, and imaging features of 12 patients with perisylvian ULG followed at three institutions are described. For patients with refractory seizures, we detail extracranial and intracranial electrographic recordings, surgical strategies, histopathologic analyses of the resected tissue, and outcome of surgical treatment. Descriptive statistics were used for quantitative and categorical variables. Student's t-test was used to compare means, and a p < 0.05 was considered significant. Pseudobulbar palsy and mental retardation were present in all patients with symmetrical BP-ULG. Five had refractory seizures. There was no relationship between the severity of the pseudobulbar palsy or of the mental retardation and the degree of seizure control with medication. The five patients in whom seizures were refractory to medication had significantly earlier age of onset and longer duration of epilepsy (p < 0.05). Dual pathology with associated unilateral HS was present in four. One patient with dual pathology had a temporolimbic electroclinical picture and had an anterior temporal lobectomy (ATL) based upon noninvasive evaluation. The other four had ictal semiology suggesting involvement of both temporolimbic and perisylvian cortex. Intracranial electroencephalography (EEG) showed concomitant seizure onset in the anterior temporal region and in the ipsilateral ULG in three of the four with dual pathology and in the ulegyric cortex in the one without HS. Resection guided by a combination of semiology, MRI, and extra and intracranial EEG led to complete seizure control in two and almost complete seizure control (Engel class II) in two other patients. The only surgical failure was an isolated ATL in a patient with dual pathology, and concomitant seizure onset in both lesions according to semiology and intracranial EEG. Our findings suggest that BP-ULG mimics the clinical features of bilateral perisylvian PMG. In patients with refractory seizures, recognition of this entity should lead to consideration of resective surgery despite the bilateral ULG.

Purpose To characterize the toxicity, pharmacokinetics, and pharmacodynamics of selinexor, a selective inhibitor of nuclear export, when combined with fludarabine and cytarabine, in children with relapsed or refractory leukemia. Patients and Methods Eighteen patients with relapsed or refractory acute leukemia were enrolled in the SELHEM (Selinexor With Fludarabine and Cytarabine for Treatment of Refractory or Relapsed Leukemia or Myelodysplastic Syndrome) clinical trial (NCT02212561). Selinexor, initially at 30 mg/m 2 per dose, was given orally on days 1, 3, 8, 10, 22, and 24 and was escalated according to a rolling-six design. Fludarabine 30 mg/m 2 and cytarabine 2 g/m 2 were administered on days 15 to 19. Pharmacokinetic and pharmacodynamic studies were performed on days 1 and 22. Response evaluations were performed on day 15 and at the completion of course 1. Results Among the 17 patients who were evaluable for toxicity, three were treated at 30 mg/m 2 , three at 40 mg/m 2 , six at 55 mg/m 2 , and five at 70 mg/m 2 . The most common grade 3 nonhematologic toxicity was asymptomatic hyponatremia. Two patients who were treated at 70 mg/m 2 experienced reversible cerebellar toxicity, thereby defining the dose-limiting toxicity. Pharmacokinetic parameters demonstrated that plasma exposure was dose proportional. Fifteen of 16 patients demonstrated at least a twofold increase of XPO1 mRNA, indicating inhibition of the XPO1 protein. In this group of heavily pretreated, relapsed, and refractory patients, seven of 15 evaluable patients (47%) achieved complete response or complete response with incomplete count recovery. Conclusion Selinexor, in combination with fludarabine and cytarabine, is tolerable at doses up to 55 mg/m 2 in pediatric patients with relapsed or refractory leukemia. All patients who received selinexor at ≥ 40 mg/m 2 demonstrated XPO1 target inhibition. Response rates are promising and will be further explored in a phase II trial.

Simultaneous bilateral decortications via video-assisted thoracic surgery for bilateral empyema

PubMed Central

Nose, Naohiro; Anami, Toshiki

2014-01-01

Introduction Bilateral empyema is a rare and life-threatening condition that is difficult to treat. We herein report a case of bilateral empyema that was treated with simultaneous bilateral decortications via video-assisted thoracic surgery (VATS). Presentation of case A 38-year-old female complained of chest pain, dyspnea, and high grade fever lasting two weeks. Computed tomography revealed bilateral notching pleural effusion and pneumonia with atelectasis. Bilateral thoracic drainage was performed. From the right chest, white pus was drained, and Streptococcus anginosus was identified. The left drainage fluid was serous, and no bacteria were identified. We diagnosed the patient with right empyema and left para-pneumonic effusion consequent to pneumonia. Because conservative therapies could not resolve the inflammatory findings, simultaneous bilateral VATS decortications were performed. Both thoracic cavities had loculated pleural effusion. In contrast to the preoperative findings, white pus was found in not only the right, but also the left thoracic cavity. She had an uncomplicated postoperative course and recovered. Discussion Bilateral empyema that has developed to the fibrinopleural phase is difficult to treat with drains alone. Bilateral VATS decortications helped to make a definitive diagnosis and treat both sides simultaneously. Conclusion Simultaneous bilateral VATS decortications should be considered as a feasible and effective procedure for bilateral empyema that is refractory to medical treatment. PMID:25528031

This study evaluates long-term outcomes of two trabecular micro-bypass stents, one suprachoroidal stent, and postoperative prostaglandin in eyes with refractory open angle glaucoma (OAG). Prospective ongoing 5-year study of 80 eligible subjects (70 with 4-year follow-up) with OAG and IOP ≥ 18 mmHg after prior trabeculectomy and while taking 1-3 glaucoma medications. Subjects received two iStent ® trabecular micro-bypass stents, one iStent Supra ® suprachoroidal stent, and postoperative travoprost. Postoperative IOP was measured with medication and annually following medication washouts. Performance was measured by the proportion of eyes with ≥ 20% IOP reduction on one medication (the protocol-specified prostaglandin) versus preoperative medicated IOP (primary outcome); and the proportion of eyes with postoperative IOP ≤ 15 and ≤ 18 mmHg on one medication (secondary outcome). Additional clinical and safety data included medications, visual field, pachymetry, gonioscopy, adverse events, visual acuity, and slit-lamp and fundus examinations. Preoperatively, mean medicated IOP was 22.0 ± 3.1 mmHg on 1.2 ± 0.4 medications, and mean unmedicated IOP was 26.4 ± 2.4 mmHg. Postoperatively, among eyes without later cataract surgery, mean medicated IOP at all visits through 48 months was ≤ 13.7 mmHg (≥ 37% reduction), and annual unmedicated IOP was ≤ 18.4 mmHg (reductions of ≥ 30% vs. preoperative unmedicated IOP and ≥ 16% vs. preoperative medicated IOP). At all postoperative visits among eyes without additional surgery or medication, ≥ 91% of eyes had ≥ 20% IOP reduction on one medication versus preoperative medicated IOP. At month 48, 97 and 98% of eyes achieved IOP ≤ 15 and ≤ 18 mmHg, respectively, on one medication. Six eyes required additional medication, no eyes required additional glaucoma surgery, and safety measurements were favorable throughout follow-up. IOP control was achieved safely with two trabecular micro-bypass stents, one suprachoroidal stent, and postoperative prostaglandin. This microinvasive, ab interno approach introduces a possible new treatment option for refractory disease. NCT01456390. Glaukos Corporation.

Treatment-refractory anxiety; definition, risk factors, and treatment challenges

PubMed Central

Roy-Byrne, Peter

2015-01-01

A sizable proportion of psychiatric patients will seek clinical evaluation and treatment for anxiety symptoms reportedly refractory to treatment. This apparent lack of response is either due to “pseudo-resistance” (a failure to have received and adhered to a recognized and effective treatment or treatments for their condition) or to true “treatment resistance.” Pseudo-resistance can be due to clinician errors in selecting and delivering an appropriate treatment effectively, or to patient nonadherence to a course of treatment. True treatment resistance can be due to unrecognized exogenous anxiogenic factors (eg, caffeine overuse, sleep deprivation, use of alcohol or marijuana) or an incorrect diagnosis (eg, atypical bipolar illness, occult substance abuse, attention deficit-hyperactivity disorder). Once the above factors are eliminated, treatment should focus on combining effective medications and cognitive behavioral therapy, combining several medications (augmentation), or employing novel medications or psychotherapies not typically indicated as first-line evidence-based anxiety treatments.

Refractory ventricular fibrillation, resistant to conventional cardiopulmonary resuscitation (CPR), is a life threatening rhythm encountered in the emergency department. Although previous reports suggest the use of extracorporeal CPR can improve the clinical outcomes in patients with prolonged cardiac arrest, the effectiveness of this novel strategy for refractory ventricular fibrillation is not known. We aimed to compare the clinical outcomes of patients with refractory ventricular fibrillation managed with conventional CPR or extracorporeal CPR in our institution. This is a retrospective chart review study from an emergency department in a tertiary referral medical center. We identified 209 patients presenting with cardiac arrest due to ventricular fibrillation between September 2011 and September 2013. Of these, 60 patients were enrolled with ventricular fibrillation refractory to resuscitation for more than 10 min. The clinical outcome of patients with ventricular fibrillation received either conventional CPR, including defibrillation, chest compression, and resuscitative medication (C-CPR, n = 40) or CPR plus extracorporeal CPR (E-CPR, n = 20) were compared. The overall survival rate was 35%, and 18.3% of patients were discharged with good neurological function. The mean duration of CPR was longer in the E-CPR group than in the C-CPR group (69.90 ± 49.6 min vs 34.3 ± 17.7 min, p = 0.0001). Patients receiving E-CPR had significantly higher rates of sustained return of spontaneous circulation (95.0% vs 47.5%, p = 0.0009), and good neurological function at discharge (40.0% vs 7.5%, p = 0.0067). The survival rate in the E-CPR group was higher (50% vs 27.5%, p = 0.1512) at discharge and (50% vs 20%, p = 0. 0998) at 1 year after discharge. The management of refractory ventricular fibrillation in the emergency department remains challenging, as evidenced by an overall survival rate of 35% in this study. Patients with refractory ventricular fibrillation receiving E-CPR had a trend toward higher survival rates and significantly improved neurological outcomes than those receiving C-CPR.

To evaluate the efficacy of supra-Tenon capsule implantation of an Ahmed glaucoma valve (AGV) as a measure to decrease the fibrotic potential of the Tenon capsule on bleb formation and its subsequent effect on intraocular pressure (IOP) control in children with refractory glaucoma. Mansoura Ophthalmic Centre, Faculty of Medicine, Mansoura University, Egypt. A prospective interventional study. Twenty-two eyes of 12 children with refractory glaucoma underwent supra-Tenon capsule implantation of AGV. Ophthalmic examinations under general anesthesia including measurement of the corneal diameter and the IOP with Perkin's tonometer were performed preoperatively, on the first postoperative day, the first postoperative week, weekly for the first month, 2-weekly for the following 3 months, and monthly for at least 18 months. Postoperative complications and the number of glaucoma medications used preoperatively and postoperatively were recorded. The paired Student t test was used to compare preoperative and postoperative data. There were 12 eyes (54.6%) with refractory congenital glaucoma, 7 eyes (31.8%) with refractory pseudophakic glaucoma, and 3 eyes (13.6%) with refractory aphakic glaucoma. Patients included 10 male (83.3%) and 2 female (16.7%) children with a mean age of 16.3±9.7 months. The mean follow-up duration was 24.1±4.3 months. There was a statistically significant difference between the mean preoperative IOP (30.7±2.88 mm Hg) and the mean postoperative IOP (16.1±3.60 mm Hg) (t=16.22 and P=0.000, with a mean decrease in the IOP by 47.6%). The difference between the mean number of antiglaucoma medications before surgery (1.86±0.4) and after surgery (1.0±0.9) was also statistically significant (t=4.31 and P=0.000). Total success was achieved in 18 eyes (81.9%). Postoperative complications included tube exposure and slippage (10%), hypotony (10%), and hyphema (5%). Supra-Tenon capsule implantation of the AGV was successful in controlling the IOP with few postoperative complications in the management of children with refractory glaucoma.

Pharmacotherapy for Refractory and Super-Refractory Status Epilepticus in Adults.

PubMed

Holtkamp, Martin

2018-03-01

Patients with prolonged seizures that do not respond to intravenous benzodiazepines and a second-line anticonvulsant suffer from refractory status epilepticus and those with seizures that do not respond to continuous intravenous anesthetic anticonvulsants suffer from super-refractory status epilepticus. Both conditions are associated with significant morbidity and mortality. A strict pharmacological treatment regimen is urgently required, but the level of evidence for the available drugs is very low. Refractory complex focal status epilepticus generally does not require anesthetics, but all intravenous non-anesthetizing anticonvulsants may be used. Most descriptive data are available for levetiracetam, phenytoin and valproate. Refractory generalized convulsive status epilepticus is a life-threatening emergency, and long-term clinical consequences are eminent. Administration of intravenous anesthetics is mandatory, and drugs acting at the inhibitory gamma-aminobutyric acid (GABA) A receptor such as midazolam, propofol and thiopental/pentobarbital are recommended without preference for one of those. One in five patients with anesthetic treatment does not respond and has super-refractory status epilepticus. With sustained seizure activity, excitatory N-methyl-d-aspartate (NMDA) receptors are increasingly expressed post-synaptically. Ketamine is an antagonist at this receptor and may prove efficient in some patients at later stages. Neurosteroids such as allopregnanolone increase sensitivity at GABA A receptors; a Phase 1/2 trial demonstrated safety and tolerability, but randomized controlled data failed to demonstrate efficacy. Adjunct ketogenic diet may contribute to termination of difficult-to-treat status epilepticus. Randomized controlled trials are needed to increase evidence for treatment of refractory and super-refractory status epilepticus, but there are multiple obstacles for realization. Hitherto, prospective multicenter registries for pharmacological treatment may help to improve our knowledge.

Immune checkpoint inhibitors can cause severe immune-related adverse events, with immune-related diarrhea and colitis (irColitis) being among the most frequent ones. While the majority of patients with irColitis respond well to corticosteroid treatment ± other immunomodulatory drugs such as infliximab, some patients do not show resolution of their symptoms. In the present study, we analysed the frequency of therapy-refractory irColitis, the underlying cause, and useful diagnostic approaches. Between 2006 and 2016, 370 patients with metastatic malignant melanoma were treated with checkpoint inhibitors at the Department of Dermatology at the University Hospital Essen. All patients were identified for whom diarrhea and/or colitis was documented in the digital patient records. Patients who did not respond to standard immunosuppressive therapy within 2 weeks were classified as refractory. Demographic and clinical data of all patients were collected. We identified 41 patients with irColitis, the majority occurring during treatment with ipilimumab. Amongst these, 5 (12.2%) were refractory to standard immunomodulatory treatment with corticosteroids and infliximab. Therapy-refractory cases tended to show more severe inflammation in colonic biopsies (p = 0.04). In all therapy-refractory cases cytomegalovirus (CMV) was detectable. CMV-DNA in colonic biopsies and in plasma was significantly more often detectable in therapy-refractory cases (in colonic biopsies p = 0.005, in plasma: p = 0.002). Presence of serum CMV IgM and positive immunohistochemical stainings of colon biopsies for CMV were also associated with refractory colitis (p=0.021; p = 0.053). This report on CMV reactivation during management of checkpoint inhibitor-induced colitis emphasises the need for repetitive diagnostic measures in treatment-refractory irColitis.

Despite the lack of scientific studies on biofield therapies, they are widely acclaimed by patients. The mechanisms of action are not explained by current allopathic medical approaches. Warts are common and contagious viral lesions that may be refractory to standard dermatologic treatments such as cryotherapy, laser therapy, and keratolytic ointments. Biofield therapies are efficient in various pathologies. Their ability to treat warts has never been demonstrated in a scientific study with a robust methodology. Patients with refractory warts often place their trust in these alternative therapies because of the poor results obtained from traditional medicine. We propose a prospective, randomized, single-blind, assessor-blind trial to evaluate the efficacy of treatment of warts by biofield therapy. Subjects with warts on their feet or hands will be randomized into two groups: real biofield therapy versus sham therapy. The diagnosis will be made at the time of inclusion, and follow-up will take place in week 3. Comparison of pictures of the warts at baseline and after 3 weeks will be used as the primary outcome measure. The hypothesis is that the extent of the disappearance of the original wart in the group treated by real biofield therapy will be 70% and that it will be 30% in the group treated by sham therapy. Using 90% power and an alpha risk of 5%, 31 subjects are required in each group for a two-tailed proportion comparison test. To our knowledge, this is the first study to evaluate the efficacy of biofield therapy on warts. Therefore, the aim of this study is to extend knowledge of biofield therapy to another area of medicine such as dermatology and to propose complementary or alternative practices to improve patient well-being. The main strength of the study is that it is a randomized, single-blind, assessor-blind, placebo-controlled study. ClinicalTrials.gov identifier: NCT02773719 . Registered on 22 April 2016.

Psychogenic Respiratory Distress: A Case of Paradoxical Vocal Cord Dysfunction and Literature Review

PubMed Central

Leo, Raphael J.; Konakanchi, Ramesh

1999-01-01

Background: Pulmonary disease such as asthma is a psychosomatic disorder vulnerable to exacerbations precipitated by psychological factors. A case is described in which a patient thought to have treatment-refractory asthma was discovered to have a conversion reaction, specifically paradoxical vocal cord dysfunction (PVCD), characterized by abnormal vocal cord adduction during inspiration. Data Sources: Reports of PVCD were located using a MEDLINE search and review of bibliographies. MEDLINE (English language only) was searched from 1966 through December 1998 using the terms functional asthma, functional upper airway obstruction, laryngeal diseases, Munchausen's stridor, paradoxical vocal cord dysfunction, psychogenic stridor, respiratory stridor, vocal cord dysfunction, and vocal cord paralysis. A total of 170 cases of PVCD were reviewed. Study Findings: PVCD appears to be significantly more common among females. PVCD spans all age groups, including pediatric, adolescent, and adult patients. PVCD was most often misdiagnosed as asthma or upper airway disease. Because patients present with atypical and/or refractory symptoms, several diagnostic tests are employed to evaluate patients with PVCD; laryngoscopy is the most common. Direct visualization of abnormal vocal cord movement is the most definitive means of establishing the diagnosis of PVCD. A number of psychiatric disturbances are related to PVCD, including conversion and anxiety disorders. PVCD is associated with severe psychosocial stress and difficulties with modulation of intense emotional states. Conclusions: Psychogenic respiratory distress produced by PVCD can be easily misdiagnosed as severe or refractory asthma or other pulmonary disease states. Recognition of PVCD is important to avoid unnecessary medications and invasive treatments. Primary care physicians can detect cases of PVCD by attending to clinical symptoms, implementing appropriate laboratory investigations, and examining the psychological covariates of the disorder. Psychotherapy and speech therapy are effective in treating most cases of PVCD. PMID:15014694

To evaluate the effect of pulsed radiofrequency (PRF) stimulation of the thoracic medial branch of the dorsal ramus in patients with chronic thoracic facet joint (TFJ) pain who were refractory to medial branch block (MBB). This was a prospective, observational study. The author retrospectively reviewed data from 72 patients who had received therapeutic MBB with 0.5 mL of 2% lidocaine mixed with 0.5 mL of 0.25% bupivacaine to treat TFJ-origin upper or midback pain. Of these patients, 20 were included to evaluate the effects of PRF on the thoracic medical branch to manage TFJ pain refractory to therapeutic MBB. PRF stimulation was administered at 5 Hz and a 5-millisecond pulsed width for 360 seconds at 45 V. The pain-reducing effect of the PRF procedure was evaluated via the numeric rating scale (NRS) at 1, 2, and 3 months after treatment. Successful pain relief was defined as ≥50% reduction in the NRS score compared with the score before treatment. The NRS scores changed significantly over time (pretreatment, 6.0 ± 1.0; 1 month, 3.3 ± 2.2; 2 months, 3.9 ± 2.1; and 3 months, 4.0 ± 2.2). At 1, 2, and 3 months after the PRF procedure, the NRS scores were significantly reduced compared with the scores before the treatment. Eleven (55%) of 20 patients reported successful pain relief at 3 months after PRF. The author suggests that PRF on the thoracic medial branch is an effective and safe interventional technique for the control of chronic TFJ pain. Copyright © 2017 Elsevier Inc. All rights reserved.

Celiac disease is an enteropathy caused by dietary gluten. The combination of serologic, genetic and histologic data has led to description of other categories of this disease. There are a number of patients with iron deficiency anemia (IDA) that do not respond to iron treatment and may be repeated for many times, Therefore, we aimed to investigate celiac disease in this group. In this cross sectional transverse prospective study from August 2011 to February 2013, in a Pediatric care clinic affiliated to Shiraz University of Medical Sciences, 184 children including 92 IDA patients who responded to treatment using iron supplement, 45 non-responding iron deficient patients, and 47 healthy individuals, with the maximum age of 18 years, with written consent from their parents, participated in serologic screening (with Anti-TTG antibody and anti-Endomysial antibody) for celiac disease. Patients with at least one positive serology test underwent multiple mucosal biopsy from bulb and duodenum. Among 184 participants, 19 (10.3%) subjects had positive serologic test for celiac disease, including 13 (28.9%) patients in the group with refractory IDA, 5 (5.4%) patients in the group with treated IDA, and 1 patient in the healthy group. The frequency of positive serologic test in the group with IDA resistant to treatment was prominently higher than the other two groups (P<0.001). Among the patients with positive serologic celiac test who underwent endoscopy and biopsy, no histologic evidence of celiac disease was seen. They were diagnosed as potential celiac disease. Frequency of potential celiac disease in patients with refractory IDA was higher than control the subjects. Therefore, we recommend serologic screening for early detection and minimizing the complications of celiac disease and repeated iron therapy for this group.

Although vaginismus is a common sexual dysfunction in Saudi Arabia, there are limited data concerning the treatment modalities associated with patients with symptoms of vaginismus. This study is aimed to evaluate the presentation and different modalities of management in patients with severe refractory vaginismus in western Saudi Arabia. Successful penetrative sexual intercourse suggesting that common elements of the therapies used were successful. A retrospective study of patients presenting with severe refractory vaginismus treated in Jeddah, Saudi Arabia. The subjects were 15 women with third to fourth degree vaginismus who presented to King Abdulazziz University Hospital between January 1, 2008 and January 1, 2009. The mean age of the participants was 23 years. The mean duration of marriage before seeking medical advice was 12 months. Six patients had undergone conventional therapy successfully. The other six cases, four of which had a previous history of treatment failure, and two who were unresponsive to 4 months of conventional therapy were offered botulinum toxin type A. Five patients who received the Botox therapy had satisfactory intercourse on the same day of the treatment. One patient required a repeat injection after 2 months for recurrent vaginismus. Three of the 15 patients refused the treatment as they were already divorced and had only come in to exclude organic causes for their condition. Vaginismus is an overlooked topic in conservative societies such as Saudi Arabia. For most patients, not knowing who to confide in or where to turn to plays a major role in the under diagnosis of vaginismus. Conventional therapy proved effective in mild and moderate cases, while botulinum toxin has a more rapid effect and was thus more effective in severe cases. © 2011 International Society for Sexual Medicine.

Purpose: To describe long-term outcomes and complications of Ahmed glaucoma valve (AGV) implantation in subjects with refractory glaucoma at Farabi Eye Hospital, Tehran, Iran. Materials and Methods: This retrospective cohort study evaluated patient records of all subjects with refractory glaucoma who had undergone AGV implantation up to January 2013. The main outcome measure was the surgical success rate. Complete success was defined as intraocular pressure (IOP) <22 mmHg, without anti-glaucoma medications or additional surgery. Qualified success was IOP <22 mmHg regardless of number of anti-glaucoma medications. In all cases, loss of vision (no light perception) was considered an independent indicator of failure. Data were also collected on intraoperative and postoperative complications. Results: Twenty-eight eyes were included in the study. With a mean follow-up of 48.2 ± 31.7 months (median: 40.50 months; range: 3–124 months), the IOP decreased from a mean preoperative value of 30.8 ± 5.6 mmHg to 20.0 ± 6.4 mmHg at last visit. The number of medications decreased from 3.7 ± 0.4 preoperatively to 2.5 ± 1.1 postoperatively. Cumulative qualified success was achieved in 69% of eyes. Mean time to failure according to qualified success criteria was 92.3 ± 9.4 months. Postoperative complications were recorded in 16 (57.1%) eyes. The most common complication was focal endothelial corneal decompensation at the site of tube-cornea touch. Conclusion: AGV implantation with adjunctive topical anti-glaucoma drops controlled IOP in approximately 70% of eyes with refractory glaucoma with a median of 40.5 months of follow-up. However, complication rates were higher. PMID:26957848

To gauge consensus regarding a proposed definition for refractory migraine proposed by Refractory Headache Special Interest Section, and where its use would be most appropriate. Headache experts have long recognized that a subgroup of headache sufferers remains refractory to treatment. Although different groups have proposed criteria to define refractory migraine, the definition remains controversial. The Refractory Headache Special Interest Section of the American Headache Society developed a definition through a consensus process, assisted by a literature review and initial membership survey. A 12-item questionnaire was distributed at the American Headache Society meeting in 2007 during a platform session and at the Refractory Headache Special Interest Section symposium. The same questionnaire was subsequently sent to all American Headache Society members via e-mail. A total of 151 responses from AHS members form the basis of this report. The survey instrument was designed using Survey Monkey. Frequencies and percentages of the survey were used to describe survey responses. American Headache Society members agreed that a definition for refractory migraine is needed (91%) that it should be added to the International Classification of Headache Disorders-2 (86%), and that refractory forms of non-migraine headache disorders should be defined (87%). Responders believed a refractory migraine definition would be of greatest value in selecting patients for clinical drug trials. The current refractory migraine definition requires a diagnosis of migraine, interference with function or quality of life despite modification of lifestyle factors, and adequate trials of acute and preventive medicines with established efficacy. The proposed criteria for the refractory migraine definition require failing 2 preventive medications to meet the threshold for failure. Although 42% of respondents agreed with the working definition of refractory migraine, 43% favored increasing the number to 3 (50%) or 4 (26%) preventive treatment failures. When respondents were asked if they felt that the proposed definition was appropriate to select patients for invasive procedures (patent foramen ovale repair or stimulators) only 44% agreed. There is a consensus for a need for a definition for refractory migraine and that it should be added to the International Classification of Headache Disorder-2. There was also general agreement by the responders that refractory forms of non-migraine headache disorders should be defined.

IMPORTANCE Depression is frequently undiagnosed in patients with chronic rhinosinusitis (CRS) and affects quality of life, productivity, and health care use. OBJECTIVE To examine depression-specific outcomes after medical or surgical treatment of CRS. DESIGN, SETTING, AND PARTICIPANTS A multi-institutional, prospective study of patients with refractory CRS treated at tertiary academic rhinology centers was performed from March 1, 2011, to November 1, 2015. Data analysis was performed from October 1, 2015, to November 1, 2015. INTERVENTIONS Patients self-selected to undergo continued medical management or endoscopic sinus surgery for refractory CRS. MAIN OUTCOMES AND MEASURES Patients completed the 22-item Sinonasal Outcome Test (SNOT22), Rhinosinusitis Disability Index (RSDI), Pittsburgh Sleep Quality Index (PSQI), and missed productivity and medication use questionnaires before and at least 6 months after treatment. Computed tomography and endoscopy scoring were performed with reviewers masked to patient-reported data. Depression-specific outcomes were recorded using the 2-item Patient Health Questionnaire (PHQ2). RESULTS Baseline data were available on 685 patients, with 167 (24.4%) having depression according to the PHQ2 scores. The mean (SD) age of the patients was 50.5 (15.0) years, and 332 (48.4%) were male. Revision surgery status was the only baseline factor associated with depression (53.9%vs 38.0%, P < .001). Patients with depression had worse baseline SNOT22 (mean, 64.5 vs 47.6), PSQI (mean, 12.8 vs 8.4), productivity (mean, 22.8 vs 5.2 days missed), and medication use scores for oral antibiotics (mean, 23.8 vs 14.8) and oral corticosteroids (mean, 17.8 vs 9.9) (P < .001 for all). Medical and surgical treatments had similar outcomes for patients with depression with mean improvement in the PHQ2 scores from 3.96 to 1.91 (P < .001), and 110 of 167 patients (65.9%) categorized as having depression at baseline were categorized as not having depression after treatment. Improvements in the PHQ2 scores were associated with improvements in the SNOT22, PSQI, oral antibiotic use, and productivity scores (P ≤ .001 for all). CONCLUSIONS AND RELEVANCE Depression is a common comorbidity in patients with CRS and affects numerous quality-of-life and health care outcomes. There are few objective baseline factors to aid physicians in identifying depression in patients with CRS. Medical and surgical treatments for CRS improve depression and related clinical outcomes.

Introduction Management of chronic angina has evolved dramatically in the last few decades with several options for pharmacotherapy outlined in various evidence-based guidelines. Areas covered There is a growing list of drugs that are currently being investigated for treatment of chronic angina. These also include several herbal medications, which are now being scientifically evaluated as potential alternative or even adjunctive therapy for angina. Gene- and cell-based therapies have opened yet another avenue for management of chronic refractory angina in ‘no-option’ patients who are not candidates for either percutaneous or surgical revascularization and are on optimal medical therapy. An extensive review of literature using PUBMED, Cochrane database, clinical trial databases of USA and European Union was done and summarized in this review. This review will attempt to discuss the traditional as well as novel therapeutic agents for angina. Expert opinion Several pharmacological and non-pharmacological therapeutic options are now available for treatment and management of chronic refractory angina. Renewed interest in traditional therapies and cell- and gene-based modalities with targeted drug delivery systems will open the doors for personalized therapy for patients with chronic refractory angina.

Everolimus and axitinib are approved in the US to treat patients with advanced renal cell carcinoma (RCC) after failure on sunitinib or sorafenib, and one prior systemic therapy (e.g., sunitinib), respectively. Two indirect comparisons performed to evaluate progression-free survival in patients treated with everolimus vs axitinib suggested similar efficacy between the two treatments. Therefore, this analysis compares the lifetime costs of these two therapies among sunitinib-refractory advanced RCC patients from a US payer perspective. A Markov model was developed to simulate a cohort of sunitinib-refractory advanced RCC patients and estimate the cost of treating patients with everolimus vs axitinib. The following health states were included: stable disease without adverse events (AEs), stable disease with AEs, disease progression (PD), and death. The model included the following resources: active treatments, post-progression treatments, adverse events, physician and nurse visits, scans and tests, and palliative care. Resource utilization inputs were derived from a US claims database analysis. Additionally, a 3% annual discount rate was applied to costs, and the robustness of the model results was tested by conducting sensitivity analyses, including those on dosing scheme and post-progression treatment costs. Base case results demonstrated that patients treated with everolimus cost an average of $12,985 (11%) less over their lifetimes than patients treated with axitinib. The primary difference in costs was related to active treatment, which was largely driven by axitinib's higher dose intensity. RESULTS remained consistent across sensitivity analyses for AE and PD treatment costs, as well as dose intensity and discount rates. The results suggest that everolimus likely leads to lower lifetime costs than axitinib for sunitinib-refractory advanced RCC patients in the US.

Background Autologous NK cell therapy can treat a variety of malignancies, but is limited by patient-specific variations in potency and cell number expansion. In contrast, allogeneic NK cell lines can overcome many of these limitations. Cells from the permanent NK-92 line are constitutively activated, lack inhibitory receptors and appear to be safe based on two prior phase I trials. Materials and Methods We conducted a single-center, non-randomized, non-blinded, open-label, Phase I dose-escalation trial of irradiated NK-92 cells in adults with refractory hematological malignancies who relapsed after autologous hematopoietic cell transplantation (AHCT). The objectives were to determine safety, feasibility and evidence of activity. Patients were treated at one of three dose levels (1 × 109 cells/m2, 3 × 109 cells/m2 and 5 × 109 cells/m2), given on day 1, 3 and 5 for a planned total of six monthly cycles. Results Twelve patients with lymphoma or multiple myeloma who relapsed after AHCT for relapsed/refractory disease were enrolled in this trial. The treatment was well tolerated, with minor toxicities restricted to acute infusional events, including fever, chills, nausea and fatigue. Two patients achieved a complete response (Hodgkin lymphoma and multiple myeloma), two patients had minor responses and one had clinical improvement on the trial. Conclusions Irradiated NK-92 cells can be administered at very high doses with minimal toxicity in patients with refractory blood cancers, who had relapsed after AHCT. We conclude that high dose NK-92 therapy is safe, shows some evidence of efficacy in patients with refractory blood cancers and warrants further clinical investigation. PMID:29179517

The prognosis of relapsed or refractory aggressive non-Hodgkin's lymphoma (NHL) after front-line therapy remains poor. The development of more effective and less toxic salvage regimens remains a major challenge. Survivin is a member of the family of inhibitors of apoptosis, and survivin was associated with short survival and bad prognosis. This study was to evaluate the efficacy of GDP regimen (gemcitabine, dexamethasone and cisplatin) on relapsed or refractory aggressive NHL and various prognostic factors with special emphasis on survivin and observe the . Forty-six patients with relapsed and refractory NHL, intermediate or high-grade NHL (Revised European American Lymphoma Classification), who at least one regimen were enrolled into this study, which was carried out at Department, , Tanta University from July 2012 to July 2014. The patients were treated with GDP regimen (gemcitabine 1,000 mg/m(2) on days one and eight, dexamethasone 40 mg on days 1-3, and cisplatin 25 mg/m(2) on days 1-3) every 3 weeks. The efficacy and adverse events were evaluated according to the WHO criteria. All patients were assessed for efficacy and toxicity. The overall response rate was 58.7 %. Fourteen patients showed a complete response, thirteen partial responses, twelve stable diseases, and seven progressive disease. The 24-month overall survival was 50.8 %. Survivin is associated with low overall response and shorter overall survival. Grade 3 anemia was observed in four patients, grade 3 leucopenia in six patients, grade 3 neutropenia in six patients, and grade 3 thrombocytopenia in four patients. Non-hematologic toxicity included grade 3 infection in four patients. The present schedule of GDP showed modest efficacy and mild toxicity in patients with relapsed or refractory aggressive NHL.

Although severe knee osteoarthritis with refractory pain is commonly treated surgically, this is often not an option for patients with poor health status or unwillingness to undergo major surgery. We examined the efficacy of radiofrequency application to sensory nerves as a novel alternative treatment for refractory knee pain. This study was an open-label, nonrandomized, and controlled study. Patients complaining of refractory anteromedial knee pain associated with radiological osteoarthritis (moderate or severe) were included. They were assigned to one of two groups: those receiving radiofrequency thermocoagulation (N = 18) or those receiving nerve block (N = 17), depending on the time period that they were referred to the clinic. Radiofrequency current or local anesthetics was applied to the medial retinacular nerve and the infrapatellar branch of the saphenous nerve. Western Ontario McMaster Universities osteoarthritis index score, pain visual analog scale (VAS), and patient's global assessment were assessed with a minimum follow-up of 6 months.   Radiofrequency treatment significantly decreased knee pain as measured by VAS for 12 weeks compared with the control group. In terms of responders, more patients in the RF group responded to the treatment than in the control group. The differences were statistically significant at 4 weeks, 8 weeks, and 12 weeks in pain VAS. Eight patients (44%) treated with radiofrequency rated excellent or good but only three (18%) in the control group rated good, although the difference was not statistically significant. Some patients were able to benefit substantially from radiofrequency treatment. Even if its effective period is limited, radiofrequency application is a promising treatment to alleviate refractory anteromedial knee pain with osteoarthritis. Further experience and technical improvements are needed to establish its role in the management of knee osteoarthritis. Wiley Periodicals, Inc.

Epistaxis: The role of arterial embolization.

Epistaxis is defined as flow of blood from the nasal fossae and is a common and benign disorder in the great majority of cases which does not require medical care. It may however become a genuine medical or surgical emergency because of the amount, repeated episodes or patient's medical vulnerability (such as coronary artery disease patients). Epistaxis may be either primary or a symptom of an underlying disease. Four levels of problems need to be answered faced with epistaxis: recognizing it, and in particular not missing "epistaxis" due to swallowed blood or venous hemorrhage, which falls outside of the scope of interventional radiology; establishing the amount and its repercussions, particularly as a decompensating factor in another disease; investigating its cause and in particular never missing a tumor (male adolescents); obtaining hemostasis. Epistaxis varies not only in type and cause but must be considered in its clinical context. Arterial embolization is a treatment of choice for severe refractory epistaxis and some hemorrhages. When carried out by trained operators, it is an effective method with few risks of complications and is increasingly being used in reference centers (Brinjikji et al.). It remains, however, a method which is less widely used than surgery, particularly in the United States where in a series of 69,410 patients treated over the last 10 years for refractory epistaxis, 92.6% underwent surgical ligation, 6.4% embolization and 1% combined treatments (Brinjikji et al.). Epistaxis is occasionally catastrophic and requires extremely urgent management. In each case, close collaboration with the surgeon, the presence of an intensive care anesthetist and at least sedation are all factors which improve management and therefore the results of embolization. All patients and/or their friends/close family should have given "reliable, clear and appropriate" information. Copyright © 2015 Éditions françaises de radiologie. Published by Elsevier Masson SAS.

Summary Children with refractory epilepsy who are co-treated with the ketogenic diet (KD) and carbonic anhydrase inhibitor (CA-I) anti-epileptic medications including topiramate (TPM) and zonisamide (ZNS) are at risk for urolithiasis. Retrospective chart review of all children treated with ketogenic therapy at our institution was performed in order to estimate the minimal risk of developing signs or symptoms of stone disease. Children (N = 93) were classified into groups according to KD +/− CA-I co-therapy. Fourteen patients had occult hematuria or worse, including 6 with radiologically confirmed stones. Three of 6 calculi developed in the KD + ZNS group of 17 patients who were co-treated for a cumulative total of 97 months (3.1 stones per 100 patient months). One confirmed stone was in the KD + TPM group of 22 children who were co-treated for a cumulative total of 263 months (0.4 stones per 100 patient months). All six patients had at least three of five biochemical risk factors including metabolic acidosis, concentrated urine, acid urine, hypercalciuria and hypocitraturia. Standard of care interventions to minimize hypercalciuria, crystalluria and stone formation used routinely by pediatric nephrologists should also be prescribed by neurologists treating patients with combination anti-epileptic therapy. Non-fasting KD initiation, fluid liberalization, potassium citrate prophylaxis as well as regular laboratory surveillance are indicated in this high risk population. PMID:20466520

To investigate efficacy and safety of repeated dexamethasone (DEX) implants over 24 months, in diabetic macular edema (DME) eyes that were treatment naive compared with eyes refractory to anti-vascular endothelial growth factor treatment, in a real-life environment. This multicenter international retrospective study assessed best-corrected visual acuity and central subfield thickness (CST) of naive and refractory eyes to anti-vascular endothelial growth factor injections treated with dexamethasone implants. Safety data (intraocular pressure rise and cataract surgery) were recorded. A total of 130 eyes from 125 patients were included. Baseline best-corrected visual acuity and CST were similar for naive (n = 71) and refractory eyes (n = 59). Both groups improved significantly in vision after 24 months (P < 0.001). However, naive eyes gained statistically significantly more vision than refractory eyes (+11.3 ± 10.0 vs. 7.3 ± 2.7 letters, P = 0.01) and were more likely to gain ≥10 letters (OR 3.31, 95% CI 1.19-9.24, P = 0.02). At 6, 12, and 24 months, CST was significantly decreased compared with baseline in both naive and refractory eyes; however, CST was higher in refractory eyes than in naive eyes (CST 279 ± 61 vs. 313 ± 125 μm, P = 0.10). Over a follow-up of 24 months, vision improved in diabetic macular edema eyes after treatment with dexamethasone implants, both in eyes that were treatment naive and eyes refractory to anti-vascular endothelial growth factor treatment; however, improvement was greater in naive eyes.

Recurrent pericarditis is a troublesome complication of idiopathic acute pericarditis and occurs more frequently in pediatric patients after cardiac surgery (postpericardiotomy syndrome). Conventional treatment with nonsteroidal antiinflammatory drugs, corticosteroids, and colchicine is not always effective or may cause serious adverse effects. There is no consensus, however, on how to proceed in those patients whose disease is refractory to conventional therapy. In such cases, human intravenous immunoglobulin, immunosuppressive drugs, and biological agents have been used. In this report we describe 2 patients with refractory recurrent pericarditis after cardiac surgery who were successfully treated with 3 and 5 monthly high-dose (2 g/kg) intravenous immunoglobulin until resolution of the effusion. Our experience supports the effectiveness and safety of this therapy. Copyright © 2014 by the American Academy of Pediatrics.

Generalized convulsive status epilepticus (GCSE) is one of the most common neurologic emergencies and can be associated with significant morbidity and mortality if not treated promptly and aggressively. Management of GCSE is staged and generally involves the use of life support measures, identification and management of underlying causes, and rapid initiation of anticonvulsants. The purpose of this article is to review and evaluate published reports regarding the treatment of impending, established, refractory, and super-refractory GCSE in pediatric patients. PMID:26380568

The mainstay of treatment for thrombotic thrombocytopenic purpura (TTP) is plasma exchange (PE), but the role of splenectomy is still undefined. The records of all patients with TTP at a single center over a 20-year period were retrospectively reviewed. Response to plasma exchange was determined. The outcome of patients treated with splenectomy in the setting of TTP was evaluated. Sixty-one patients had been treated for TTP. Thirty-nine patients (64%) achieved complete remission (CR) with PE, nineteen (31%) of these achieving sustained CR and seventeen (28%) with relapsed TTP. Twenty patients (33%) had PE refractory TTP and two patients (3%) had PE dependent TTP. During this time period, 10 patients (16%) underwent splenectomy, four patients (7%) for PE dependent TTP, three (5%) for relapsed TTP, and three (5%) for refractory TTP. All of the patients achieved CR after splenectomy. Two patients who had undergone splenectomy had subsequent relapses, both with previously relapsed TTP. In relapsed patients the relapse rate after splenectomy was 0.27 events per patient year compared to 0.6 events per patient year before splenectomy. Median follow-up after splenectomy was 19 months (range 0.13-90 months). In conclusion, relapses in TTP can be managed successfully with additional PE or with splenectomy. PE dependent or refractory TTP can be successfully treated with splenectomy.

To evaluate clinical feasibility and safety of magnetic resonance imaging-guided high-intensity focused ultrasound (MR-HIFU) treatment of symptomatic osteoid osteoma and to compare clinical response with standard of care treatment. Nine subjects with radiologically confirmed, symptomatic osteoid osteoma were treated with MR-HIFU in an institutional review board-approved clinical trial. Treatment feasibility and safety were assessed. Clinical response was evaluated in terms of analgesic requirement, visual analog scale pain score, and sleep quality. Anesthesia, procedure, and recovery times were recorded. This MR-HIFU group was compared with a historical control group of 9 consecutive patients treated with radiofrequency ablation. Nine subjects (7 male, 2 female; 16 ± 6 years) were treated with MR-HIFU without technical difficulties or any serious adverse events. There was significant decrease in their median pain scores 4 weeks within treatment (6 vs 0, P < .01). Total pain resolution and cessation of analgesics were achieved in 8 of 9 patients after 4 weeks. In the radiofrequency ablation group, 9 patients (8 male, 1 female; 10 ± 6 years) were treated in routine clinical practice. All 9 demonstrated complete pain resolution and cessation of medications by 4 weeks with a significant decrease in median pain scores (9 vs 0, P < .001). One developed a second-degree skin burn, but there were no other adverse events. Procedure times and treatment charges were comparable between the 2 groups. This pilot study shows that MR-HIFU treatment of osteoid osteoma refractory to medical therapy is feasible and can be performed safely in pediatric patients. Clinical response is comparable with standard of care treatment but without any incisions or exposure to ionizing radiation. ClinicalTrials.govNCT02349971. Copyright © 2017 Elsevier Inc.

Prediction of treatment refractoriness in ulcerative colitis and Crohn's disease--do we have reliable markers?

PubMed

Gelbmann, C M

2000-05-01

Treatment refractoriness is a severe problem in the management of patients with ulcerative colitis and Crohn's disease. Despite some promising new therapeutic approaches, corticosteroids are still the preferential primary treatment for moderate to severe Crohn's disease and of severe ulcerative colitis. However, clinical response to corticosteroids varies, and many patients are resistant to such treatment. Since corticosteroids have frequent and even severe side effects, and toxicity increases with chronic steroid intake, factors predictive of response to such treatment would be very helpful for decisions on further management of these patients. At least in severe attacks of ulcerative colitis, the consensus seems to be that a high frequency of bowel movements as well as a high C-reactive protein and low serum albumin recorded after a few days of intensive medical treatment are important signs for early prediction of treatment failure in the majority of the patients. In Crohn's disease thus far, data on predictive factors are conflicting. No reliable marker with sufficient predictive value for treatment refractoriness could be identified. This might be due to the tremendous heterogeneity of Crohn's disease with many clinical phenotypes, which requires subgroup analysis with sufficient numbers of patients. Corticosteroids as well as other immunomodulating and immunosuppressive medications interfere with the immune system, which plays a central role in the mediation of intestinal inflammation. Treatment refractoriness might have its origin in specific immunological peculiarities eventually reflected in abnormal immunological, biochemical, and clinical parameters. Further exploration of those parameters to predict treatment refractoriness in patients with ulcerative colitis or Crohn's disease is of great clinical importance for safe and efficient management of patients.

The management of refractory recurrent pericarditis is challenging. Previous clinical reports have noted a beneficial effect of high-dose intravenous human immunoglobulins (IvIgs) in isolated and systemic inflammatory disease-related forms. In this article, we analyzed retrospectively our clinical experience with IvIg therapy in a series of clinical cases of pericarditis refractory to conventional treatment. We retrospectively analyzed 9 patients (1994 to 2010) with refractory recurrent pericarditis, who received high-dose IvIg as a part of their medical treatment. Nonsteroidal anti-inflammatory drugs (NSAIDs), steroids, or colchicine treatment was not discontinued during IvIg treatment. No patients had a history of autoimmune or connective tissue diseases. During an average period of 11 months from the first recurrence, patients had experienced a mean of 5 relapses before the first IvIg treatment. In 4 cases, patients showed complete clinical remission with no further relapse after the first IvIg cycle. Two patients experienced a single minor relapse, responsive to short-term nonsteroidal anti-inflammatory drugs. In 2 patients, we performed a second cycle of IvIg after a recurrence of pericarditis, with subsequent complete remission. One patient did not respond to 3 cycles of IvIg and subsequently underwent pericardial window and long-term immunosuppressive treatment. No major adverse effect was observed in consequence of IvIg administration in all the cases. In conclusion, although IvIg mode of action is still poorly understood in this setting, this treatment can be considered as an option in patients with recurrent pericarditis refractory to conventional medical treatment and, in our small series, has proved to be effective in 8 of 9 cases.

Gross, intractable hematuria is rare in children. Although the role of epsilon aminocaproic acid in the management of refractory hematuria is well established in the adult population, few data exist about its use in children for this indication. We present our initial experience with epsilon aminocaproic acid for the treatment of intractable hematuria after more conservative measures failed, and propose an algorithm for administration of epsilon aminocaproic acid in children. We reviewed the charts of all patients treated with epsilon aminocaproic acid for intractable gross hematuria at our institution during a period of 36 months. All patients underwent hematological evaluation and any underlying bleeding dyscrasias were addressed. All patients also underwent renal and bladder ultrasound, retrograde pyelogram and ureteroscopy. Demographic information, medical and surgical histories, and epsilon aminocaproic acid dosing and outcomes were recorded. Three boys and 1 girl 11 to 17 years old were treated with epsilon aminocaproic acid. Three patients had sickle trait (1 with nutcracker phenomenon) and 1 had hemophilia A. Three patients required packed red blood cell transfusions to maintain hematocrit. Three renal angiograms were performed, all of which were nondiagnostic. Duration of hematuria ranged from 1 to 52 weeks before administration of epsilon aminocaproic acid. Endoscopic evaluation demonstrated hematuria localized to 1 ureteral orifice in all 4 patients. All patients received 100 mg/kg epsilon aminocaproic acid orally every 6 hours, which uniformly led to cessation of hematuria. Epsilon aminocaproic acid is useful for the management of gross refractory hematuria when more conservative measures fail. Because of its potential side effects, it should be used cautiously. 2010 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.

Tremor is a disabling condition, common to several neurodegenerative diseases. Lesioning procedures and deep brain stimulation, respectively, of the ventralis intermedius nucleus for intentional tremor, and of the subthalamic nucleus for parkinsonian resting tremor, have been introduced in clinical practice for patients refractory to medical treatment. The combination of high-energy focused ultrasound (HIFUS) with sophisticated magnetic resonance (MR) instrumentation, together with accurate knowledge of the stereotactic brain coordinates, represents a revolution in neuromodulation. At the Neurosurgical Clinic and the Radiology Department of the University of Palermo,, two patients affected by severe and refractory forms of intentional tremor were treated by MRI-guided FUS (MRgFUS) with a unique 1.5 T MR scanner prototype that uses FUS. This apparatus is the only one of its type in the world." This is the first Italian experience, and the second in Europe, of treatment with MRI-gFUS for intentional tremor. But this is the very first experience in which a 1.5 T MRI apparatus was used. In both patients, the treatment completely abolished the tremor on the treated side, with results being excellent and stable after 7 and 5 months, respectively; no side effects were encountered. MRgFUS, recently introduced in clinical practice, and widely used at several clinical centers, has been shown to be a valid therapeutic alternative in the treatment of tremor in several neurodegenerative diseases. It is virtually safe, noninvasive, and very efficacious. We report this technique in which a 1.5 T MR scanner was used. Further investigations with long-term follow up and larger clinical series are needed.

Early Use of the NMDA Receptor Antagonist Ketamine in Refractory and Superrefractory Status Epilepticus

PubMed Central

Zeiler, F. A.

2015-01-01

Refractory status epilepticus (RSE) and superrefractory status epilepticus (SRSE) pose a difficult clinical challenge. Multiple cerebral receptor and transporter changes occur with prolonged status epilepticus leading to pharmacoresistance patterns unfavorable for conventional antiepileptics. In particular, n-methyl-d-aspartate (NMDA) receptor upregulation leads to glutamate mediated excitotoxicity. Targeting these NMDA receptors may provide a novel approach to otherwise refractory seizures. Ketamine has been utilized in RSE. Recent systematic review indicates 56.5% and 63.5% cessation in seizures in adults and pediatrics, respectively. No complications were described. We should consider earlier implementation of ketamine or other NMDA receptor antagonists, for RSE. Prospective study of early implementation of ketamine should shed light on the role of such medications in RSE. PMID:25649724

Lafora disease is one of the rare, most fatal progressive myoclonic epilepsies reported. We present a case of a teenager with intractable seizures and progressive mental decline, diagnosed as Lafora body disease on axillary skin biopsy. He was admitted with status epilepticus with refractory myoclonic and generalised tonic clonic seizures. Despite on maximum doses of multiple antiepileptic drugs and infusions of propofol and midazolam, his seizures were refractory to all forms of medical therapy tried. Levetiracetam (LEV), a pyrrolidine derivative, was introduced; he showed a prompt response and was weaned off successfully from infusions of anticonvulsants and mechanical ventilation within 48 h of introduction of LEV, followed by an almost seizure-free status.

Medication resistant temporal lobe epilepsy occurs in a small population of patients with fragile X syndrome. We present the case of a 24-year-old man with medically refractory temporal lobe epilepsy and fragile X syndrome who underwent left anterior temporal lobectomy resulting in cessation of seizures. Our patient was diagnosed with fragile X syndrome with a fully mutated, fully methylated FMR1 gene resulting in 572 CGG repeats. He developed seizures initially controlled with Depakote monotherapy, but progressed to become medically refractive to combination treatment with Depakote, lamotrigine and zonisamide. Prolonged video EEG monitoring revealed interictal left temporal sharp waves and slowing as well as subclinical and clinical seizures, each with left temporal onset. 3T MRI was consistent with left mesial temporal sclerosis. After discussing the case in our multidisciplinary surgical epilepsy conference, he was referred for presurgical evaluation including neuropsychological testing and Wada testing. He underwent an asleep left anterior temporal lobectomy, sparing the superior temporal gyrus. Pathology showed neuronal loss and gliosis in the hippocampus and amygdala. Twelve months after surgery, the patient has not experienced a seizure. He is described by his parents as less perseverative and less restless. We have presented the case of a 24 year-old-man with fragile X syndrome who underwent successful left anterior temporal lobectomy for the treatment of medically refractory epilepsy who is now seizure free without further functional impairment. This case report demonstrates the feasibility of surgical treatment for a patient with comorbid fragile X syndrome and mesial temporal sclerosis.

We investigated the various possible reasons for uncontrolled seizures in patients under 18 years of age to determine the impact of pseudointractability. We also investigated the various forms of pseudointractability in children with uncontrolled seizures. In this cross-sectional retrospective chart review study, all patients under 18 years of age with their first seizure occurring at least 6 months prior to the referral date, taking at least one antiepileptic drug (AED), and having at least one seizure in the past 3 months were studied. The presumed reason for uncontrolled seizures was arbitrarily considered to be one of these five categories: poor adherence; wrong medication; wrong dose of the correct medication; diagnosis other than epilepsy; and finally, medically refractory epilepsy. Statistical analyses were performed using Chi-square and Fisher's Exact tests to determine potentially significant differences, and a P value less than 0.05 was considered significant. During the study period, 198 patients were referred to us due to uncontrolled seizures. Ninety patients (45%) were taking one AED, 55 (28%) were taking two AEDs, and 53 (27%) patients were taking more than two AEDs at the time of referral. Four percent of these patients did not have epilepsy. Forty-seven percent of the children with uncontrolled seizures had medically refractory epilepsy; 37% were taking the wrong AEDs; 10% were taking suboptimal doses of AEDs; and 2% had poor drug adherence. Uncontrolled seizures in children are a commonly encountered problem, particularly at epilepsy clinics. One should consider all possible reasons for these uncontrolled seizures, including non-epileptic seizures, pseudointractability, and medically refractory epilepsy. The mainstay for making a correct diagnosis is a detailed clinical history. Copyright © 2012 Elsevier Inc. All rights reserved.

We also tried to investigate the various forms of pseudointractability. In this cross-sectional study, all patients 18 years of age and older with their first seizure occurring at least six months prior to the referral date, taking at least one antiepileptic drug (AED) and having at least one seizure in the past three months were studied. The presumed reason for uncontrolled seizures was arbitrarily considered to be one of these five categories: Poor compliance; Wrong medication (misclassification); Wrong dose of the correct medication; Diagnosis other than epilepsy; and finally, Medically-refractory epilepsy. Statistical analyses were performed using Chi-square and Fisher's exact tests, and a P value less than 0.05 was considered significant. 350 patients were referred to us due to uncontrolled seizures. One hundred ninety-one (55%) were male and 159 (45%) were female. Twelve percent of the patients had diagnoses other than epilepsy, 40% had indeed medically-refractory epilepsy; 29% were taking the wrong AEDs (misclassified epilepsy); 18% were taking suboptimal doses of AEDs; and 1% had poor drug compliance. The most common reason for uncontrolled seizures among patients with idiopathic generalized epilepsy was taking the wrong AED. However, among patients with focal epilepsy, true medically-refractory epilepsy was the most common reason. Uncontrolled seizures are a commonly encountered problem, especially at epilepsy clinics and one should consider all possible reasons for these uncontrolled seizures.

The effectiveness of 6-mercaptopurine combined with azathioprine in treating severe ulcerative colitis has been shown in several adult studies. Reported pediatric experiences are rare. The purpose of this study was to investigate the safety and the potential efficacy of 6-mercaptopurine and azathioprine in the treatment of active ulcerative colitis in a pediatric population. The medical records of patients with active ulcerative colitis who were under observation at The Children's Hospital of Philadelphia and its satellite clinics from January 1984 through December 1997 were retrospectively reviewed. Patients were included who had received a diagnosis of ulcerative colitis, who met no criteria for Crohn's colitis, and who had received treatment with 6-mercaptopurine and azathioprine. They were then analyzed for the development of side effects, the indication to use 6-mercaptopurine and azathioprine, and the ability to discontinue corticosteroid use in those patients taking 5-acetylsalicylic acid products who were corticosteroid-dependent or whose disease was refractory to treatment. Excluded from the corticosteroid analyses were patients who underwent surgery for their disease and patients treated with 5-acetylsalicylic acid only. Statistical analysis was performed by the Kaplan-Meier survival curve and paired Student's t-test. In a review of 200 medical records of patients with active ulcerative colitis, 20 patients met the criteria. The patients' average age at the initiation of treatment with 6-mercaptopurine and azathioprine was 13.8 years. Sixteen patients (80%) were corticosteroid dependent and 3 (15%) had ulcerative colitis refractory to corticosteroid treatment. One patient had severe colitis treated with 5-acetylsalicylic acid only. Discontinuation of corticosteroid was accomplished in 12 (75%) of 16 patients. The median time to discontinuation of corticosteroid after initiation of 6-mercaptopurine and azathioprine therapy was 8.4 months. Eight patients (67%), observed from 3 months to 65 months, have continued without corticosteroid therapy. Side effects included pancreatitis and shingles that resulted in discontinuation of 5-acetylsalicylic acid, leukopenia corrected by withholding 6-mercaptopurine, and self-resolved hepatitis. The data support the safety of 6-mercaptopurine and azathioprine use in the treatment of pediatric patients with ulcerative colitis; side effects were minimal and reversible. Eighteen (90%) of 20 patients tolerated the therapy well. The results also show that 12 (75%) of 16 pediatric patients with ulcerative colitis will benefit from the use of 6-mercaptopurine and azathioprine after initial discontinuation of corticosteroid therapy. Although 6-mercaptopurine and azathioprine may not prevent further relapses, medical management of these flares may be less intense and may not require long-term corticosteroid use. Prospective clinical trials in pediatric patients are necessary to delineate further the role of 6-mercaptopurine and azathioprine in pediatric ulcerative colitis.

Refractory coeliac disease type I is a complicated form of coeliac disease characterised by primary or secondary resistance to a gluten-free diet with persisting or reoccurring intestinal villous atrophy and symptoms of malabsorption. Besides corticosteroids, azathioprine has been advocated for the treatment of refractory coeliac disease type I. However, tioguanine (TG) might be better tolerated and more efficacious owing to a simpler metabolism towards bioactivation. To evaluate tolerability and effectiveness of the nonconventional thiopurine derivative TG in refractory coeliac disease type I. Refractory coeliac disease type I patients treated with TG between June 2001 and November 2010 with a follow-up period of at least 1 year were included. Adverse events, laboratory values, 6-thioguanine nucleotide concentrations and rates of both clinical and histological response were evaluated at baseline and during follow-up. Twelve adult refractory coeliac disease type I patients were included. The median TG treatment duration was 14 months. Ten patients tolerated TG treatment on the long term, whereas two patients withdrew treatment due to adverse events. No nodular regenerative hyperplasia of the liver was observed. During follow-up clinical and histological response was observed in 83% and 78%, respectively. Corticosteroid dependency decreased by 50%. Tioguanine appears to be a convenient drug for the treatment of refractory coeliac disease type I based on higher histological and similar clinical response rates as compared with historical conventional therapies. © 2012 Blackwell Publishing Ltd.

Acute Worsening of Tics on Varenicline.

PubMed

Mittal, Shivam Om; Klassen, Bryan T; Hassan, Anhar; Bower, James H; Coon, Elizabeth A

The aim of this study was to report worsening of Tourette syndrome (TS) in 2 patients treated with varenicline. Abnormal dopaminergic signaling is likely involved in the pathophysiology of TS. Varenicline is a partial α4β2 nicotinic acetylcholine agonist that enhances dopamine release. Therefore, the use of varenicline may influence tics in patients with TS. We analyzed and described 2 case studies on patients with significant worsening of tics after treatment with varenicline. Patient 1 had motor tics in childhood, which completely resolved by the age of 20 years. At the age of 25 years, he started varenicline and stopped smoking. Within 2 weeks, he developed motor followed by vocal tics that persisted despite stopping varenicline and restarting smoking. The tics were complex, medically refractory, and caused severe disability at work and school (Yale Global Tic Severity Scale score, 86). Patient 2 developed motor and vocal tics in adolescence that persisted into her 20s and caused significant disability in association with psychiatric comorbidities. At the age of 31 years, she started varenicline to quit smoking, which led to a marked increase in tic frequency and severity. Varenicline was discontinued after 3 weeks with improvement to baseline tic severity (Yale Global Tic Severity Scale score, 94). Ultimately, both patients successfully underwent deep brain stimulation to bilateral centromedian/parafascicular complex thalamic nuclei for medically refractory TS. We report 2 patients with motor and/or vocal tics that had severe worsening of tics after varenicline use. This may be due to varenicline-induced increased striatal dopamine in conjunction with nicotine cessation, influencing dopamine receptor sensitivity in TS. Providers should be cautious in prescribing varenicline to patients with TS.

Non-drug treatments should be systematically associated to the medical analgesic treatment during the terminal phase of cancer. Patient 1, a 23-year-old woman, presented an adenocarcinoma of the rectum, with liver and lung metastases. Pain was initially treated by oral morphine and a combination of pregabalin and amitriptyline. Ketamine and intrathecal administration of morphine were both ineffective. Patient 2, a 69-year-old woman, presented a cutaneous T-cell lymphoma. She was admitted to the palliative care unit with mixed pain related to cutaneous lymphomatous infiltration. World Health Organization (WHO) step 3 analgesics had not been tolerated. Both patients received five consecutive 20-min sessions of repetitive transcranial magnetic stimulation to the right motor cortex. Patient 1 experienced a marked improvement of her pain over the days following the first repetitive transcranial magnetic stimulation session. Medical treatment was able to be rapidly decreased by about 50%, which restored an almost normal level of consciousness and lucidity. Patient 2's pain was also markedly decreased over the days following these five consecutive sessions, and repetitive transcranial magnetic stimulation also appeared to have had a beneficial effect on the patient's anxiety and mood. In the context of palliative care of cancer patients experiencing refractory pain that is difficult to control by the usual treatments, motor cortex repetitive transcranial magnetic stimulation, due to its noninvasive nature, can be used as an adjuvant therapy to improve various components of pain, including the emotional components. By reducing the doses of analgesics, repetitive transcranial magnetic stimulation decreases the severity of their adverse effects and improves the patient's quality of life. © The Author(s) 2015.

Cough: an unmet clinical need

PubMed Central

Dicpinigaitis, Peter V

2011-01-01

Cough is among the most common complaints for which patients worldwide seek medical attention. Thus, the evaluation and treatment of cough result in tremendous financial expenditure and consumption of health care resources. Yet, despite the clinical significance of cough, research efforts aimed at improving diagnostic capabilities and developing more effective therapeutic agents have been, to date, disappointing in their limited scope and outcomes. Acute cough due to the common cold represents the most common type of cough. Currently, available medications for the symptomatic management of acute cough are inadequate due to lack of proven efficacy and/or their association with undesirable or intolerable side effects at anti-tussive doses. Subacute cough, often representing a prolonged post-viral response, is typically refractory to standard anti-tussive therapy. Few clinical trials have evaluated therapeutic options for subacute cough. Diagnostic challenges facing the clinician in the management of chronic cough include the determination of whether symptoms of upper airway cough syndrome (formerly, postnasal drip syndrome) or gastro-oesophageal reflux disease are indeed the underlying cause of cough. Chronic, refractory unexplained (formerly, idiopathic) cough must be distinguished from cough that has not been fully evaluated and treated according to current guideline recommendations. Eagerly awaited are new safe and effective anti-tussive agents for use when cough suppression is desired, regardless of underlying aetiology of cough, as well as practical, validated ambulatory cough counters to aid clinical assessment and future research in the field of cough.

We report a case of invasive pulmonary aspergillosis in a patient taking ibrutinib, a Bruton's tyrosine kinase inhibitor used to treat refractory chronic lymphocytic leukemia. We hypothesize that ibrutinib promoted this infection by suppressing innate immune responses against Aspergillus . Clinicians should be aware of potential Aspergillus infections in patients treated with this drug.

Daratumumab is a CD38-directed monoclonal antibody approved for treating multiple myeloma (MM). Propensity score matching (PSM) based on individual patient data (IPD) was conducted to compare overall survival (OS) and progression-free survival (PFS) for daratumumab versus real-world standard of care (SOC). IPD for patients with relapsed and refractory (RR) MM treated with daratumumab monotherapy were from the GEN501 and SIRIUS studies; IPD for patients treated with SOC were from an International Myeloma Working Group (IMWG) chart review of patients with RRMM. Prior to PSM, patients treated with daratumumab had significantly longer OS (median 20.1 vs. 10.1 months, hazard ratio [HR] = 0.51 [0.39-0.67]) and PFS (median 4.0 vs. 2.8 months, HR = 0.73 [0.58-0.92]) than patients treated with SOC therapies. After PSM, daratumumab maintained a significantly prolonged OS (19.9 vs. 9.2 months, HR = 0.44 [0.31-0.63]) and PFS (3.9 vs. 1.6 months, HR = 0.56 [0.42-0.74]) compared with SOC.

We describe two patients with refractory myoclonic status epilepticus treated with the ketogenic diet. Between May 1, 2014 and January 1, 2015, two patients who met the diagnostic criteria for refractory myoclonic status epilepticus, seen at our department, were placed on the ketogenic diet and followed for a minimum of six months. One patient with myoclonic epilepsy of unknown aetiology had a 75-90% seizure reduction, and the other with progressive encephalopathy associated with myoclonic epilepsy had a 50% seizure reduction. Both patients retained good tolerability for the diet. At the last control, one patient had isolated myoclonias and EEG showed occasional generalized spike-and-polyspike waves; the patient is now successfully attending kindergarten. The quality of life of the second patient improved significantly. In both cases, the number of antiepileptic drugs was reduced. The ketogenic diet is an effective and well-tolerated treatment option for patients with refractory myoclonic status epilepticus and should be considered earlier in the course of treatment.

Long-term complete remission with belinostat in a patient with chemotherapy refractory peripheral T-cell lymphoma.

Peripheral T/NK-cell lymphomas (PTCL) are rare malignancies with a poor prognosis. Due to the lack of randomised studies, standard therapy has not been established. First-line treatment with anthracycline-based polychemotherapy followed by consolidation with high-dose therapy and autologous stem cell transplant in responding patients has demonstrated good feasibility with low toxicity in prospective studies and is widely used in eligible patients. In relapsed and refractory patients, who are not candidates for transplant approaches, therapeutic options are limited and are usually palliative. Several new agents are currently under investigation to improve the outcome of PTCL in the first line and salvage settings. Belinostat, a histone deacetylase (HDAC) inhibitor, has demonstrated broad antineoplastic activity in preclinical studies, and promising results in advanced relapsed/refractory lymphomas.Here, we report the case of a 73 year old patient with heavily pre-treated refractory PTCL in complete remission with belinostat for 39 months.

A new appraisal of iodine refractory thyroid cancer.

Thyroid cancer incidence is increasing all over the world - mostly due to an increase in the detection of small tumors that were previously undetected. A small percentage of these tumors lose the ability to uptake and/or to respond to radioiodine (RAI) therapy, especially in metastatic patients. There are several new therapeutic options that have emerged in the last 5 years to treat RAI refractory thyroid cancer patients, however, it is very important to properly identify RAI refractory patients and to clarify those appropriate for these treatments. In this review, we discuss the RAI refractory definitions and the criteria that have been suggested based on RAI uptake in the post therapy scan, as well as the response after RAI therapy and the possible molecular mechanisms involved in this process. We offer a review of the therapeutic options available at the moment and the therapeutic considerations based on a patient's individualized personal characteristics, primary tumor histology, tumor burden and location and velocity of lesion growth. © 2015 Society for Endocrinology.

Lacosamide is FDA-approved in patients 17 years or older with partial-onset epilepsy. We evaluated the efficacy and tolerability of lacosamide in children with refractory generalized epilepsy. We retrospectively reviewed records of 21 children with refractory generalized epilepsy treated with lacosamide in our institution from 2009-2013 divided into 2 subgroups- I, Lennox-Gastaut Syndrome, and II, other generalized epilepsies. Efficacy was defined as seizure freedom or ≥50% seizure reduction. Descriptive data analysis including seizure freedom was compared using c(2) analysis. There were eleven females and ten males with a mean age, of 11.9 years. Five patients became seizure free, nine had ≥50% seizure reduction, and seven had no response. Group I: seven had ≥50% improvement, one did not respond. Group II: five became seizure free, two had ≥50% improvement, five had no response. Lacosamide is effective and well tolerated in children with refractory generalized epilepsy particularly patients with Lennox-Gastaut Syndrome. © The Author(s) 2016.

To evaluate the best diagnostic technique and risk factors of the human Cytomegalovirus (HCMV) and Epstein-Barr virus (EBV) infection in inflammatory bowel disease (IBD). A cohort of 40 IBD patients (17 refractory) and 40 controls underwent peripheral blood and endoscopic colonic mucosal sample harvest. Viral infection was assessed by quantitative real-time polymerase chain reaction and immunohistochemistry, and correlations with clinical and endoscopic indexes of activity, and risk factors were investigated. All refractory patients carried detectable levels of HCMV and/or EBV mucosal load as compared to 13/23 (56.5%) non-refractory and 13/40 (32.5%) controls. The median DNA value was significantly higher in refractory (HCMV 286 and EBV 5.440 copies/10(5) cells) than in non-refractory (HCMV 0 and EBV 6 copies/10(5) cells; P < 0.05 and < 0.001) IBD patients and controls (HCMV and EBV 0 copies/10(5) cells; P < 0.001 for both). Refractory patients showed DNA peak values ≥ 10(3) copies/10(5) cells in diseased mucosa in comparison to non-diseased mucosa (P < 0.0121 for HCMV and < 0.0004 for EBV), while non-refractory patients and controls invariably displayed levels below this threshold, thus allowing us to differentiate viral colitis from mucosal infection. Moreover, the mucosal load positively correlated with the values found in the peripheral blood, whilst no correlation with the number of positive cells at immunohistochemistry was found. Steroid use was identified as a significant risk factor for both HCMV (P = 0.018) and EBV (P = 0.002) colitis. Finally, a course of specific antiviral therapy with ganciclovir was successful in all refractory patients with HCMV colitis, whilst refractory patients with EBV colitis did not show any improvement despite steroid tapering and discontinuation of the other medications. Viral colitis appeared to contribute to mucosal lesions in refractory IBD, and its correct diagnosis and management require quantitative real-time polymerase chain reaction assay of mucosal specimens.

Fecal incontinence is a socially debilitating problem for many children. We hypothesized that in selected patients with medically-refractory encopresis, placement of an appendicostomy or cecostomy tube for administration of antegrade continence enemas (ACE) would improve quality of life (QOL). We reviewed all patients with encopresis who underwent appendicostomy or cecostomy placement from 2003 to 2014 at our institution. We contacted subjects' parents by phone and administered 3 surveys: a survey reflecting current stooling habits, a disease-specific QOL survey, and the PedsQL™ QOL survey. QOL surveys were completed twice by parents, once reflecting pre-operative QOL, then again reflecting current QOL. Pre-procedure and post-procedure scores were compared by paired t-test. Ten patients underwent appendicostomy/cecostomy for encopresis. Eight completed phone surveys. All procedures were performed laparoscopically. All patients experienced fecal soiling pre-operatively, whereas 5/8 surveyed patients (63%) noted complete resolution of soiling post-procedure (p<0.01). General and disease-specific QOL improved from pre-procedure to post-procedure in the following domains: social habits, physical activity, ability to spend the night elsewhere, feeling, and overall QOL (p<0.05). PedsQL™ scores improved significantly in physical functioning, social functioning, and overall functioning (p<0.05). Antegrade continence enemas significantly improve quality of life in patients with medically-refractory encopresis, likely related to resolution of soiling. 4. Copyright © 2017.

Forecasting clinical and economic outcomes in ulcerative colitis (UC) and Crohn's disease (CD) patients is complex, but necessary. To determine: the frequency of treatment-classified clinical states; the probability of transition between states; and the economic outcomes. Newly diagnosed UC and CD patients, allocated into seven clinical states by medical and surgical treatments recorded in serial 3-month cycles, underwent Markov analysis. Over 10 years, 630 UC and 318 CD patients had 22,823 and 11,871 cycles. The most frequent clinical outcomes were medical/surgical remission (medication-free) and mild disease (on 5-aminosalicylates, antibiotics, topical corticosteroids), comprising 28% and 62% of UC cycles and 24% and 51% of CD cycles respectively. The probability of drug-response in patients receiving systemic corticosteroids/immunomodulators was 0.74 in UC, 0.66 in CD. Both diseases had similar likelihood of persistent drug-dependency or drug-refractoriness. Surgery was more probable in CD, 0.20, than UC, 0.08. In terms of economic outcomes, surgery was costlier in UC per cycle, but the outlay over 10 years was greater in CD. Drug-refractory UC and CD cases engendered high costs in the cohort. Most patients on 5-aminosalicylates, corticosteroids and immunomodulators had favourable clinical and economic outcomes over 10 years. Drug-refractory and surgical patients exhibited greater long-term expenses.

Elderly patients with relapsed and refractory acute lymphoblastic leukemia (ALL) have poor prognosis. Autologous CD19 chimeric antigen receptor-modified T (CAR-T) cells have potentials to cure patients with B cell ALL; however, safety and efficacy of allogeneic CD19 CAR-T cells are still undetermined. We treated a 71-year-old female with relapsed and refractory ALL who received co-infusion of haplo-identical donor-derived CD19-directed CAR-T cells and mobilized peripheral blood stem cells (PBSC) following induction chemotherapy. Undetectable minimal residual disease by flow cytometry was achieved, and full donor cell engraftment was established. The transient release of cytokines and mild fever were detected. Significantly elevated serum lactate dehydrogenase, alanine transaminase, bilirubin and glutamic-oxalacetic transaminase were observed from days 14 to 18, all of which were reversible after immunosuppressive therapy. Our preliminary results suggest that co-infusion of haplo-identical donor-derived CAR-T cells and mobilized PBSCs may induce full donor engraftment in relapsed and refractory ALL including elderly patients, but complications related to donor cell infusions should still be cautioned.

The aim of the present study was to determine the efficacy, side-effects and tolerability of blonanserin for treating refractory behavioural psychological symptoms of dementia (BPSD). The present study was a 12-week, prospective, structured clinical trial of blonanserin for the treatment of BPSD. The degree of cognitive function, activities of daily living score, and the degree of BPSD were determined using the Mini-Mental State Examination (MMSE), Disability Assessment for Dementia (DAD), Neuropsychiatric Inventory (NPI) and the Rating Scale for Aggressive Behaviour in the Elderly (RAGE). The severity of extrapyramidal symptoms was assessed using the Drug-Induced Extrapyramidal Symptoms scale (DIEEPS). Five patients were enrolled. These patients met the NINCDS-ADRDA criteria. The patients were prescribed more than two kinds of existing antipsychotic drugs and were considered refractory cases; the drugs were discontinued because they were ineffectual and side-effects appeared. Each drug was prescribed independently for at least 2 weeks. The mean changes (at baseline and at the last week, respectively) in the MMSE (12.25, 9.25), in the DAD (6.5, 6.75), in the RAGE (5.5, 5.3) and in the DIEEPS (0.5, 1.5) were minimal. The mean changes in the NPI were two or fewer points. Some side-effects (one gait abnormality and one pneumonia) were observed. The results of this preliminary study show that blonanserin does not have adequate efficacy for the treatment of refractory BPSD. © 2010 The Authors.

The difficult asthmatic.

Gregg, I

The most common reason why asthma presents difficulties in management is the failure to treat it with drugs which are appropriate and taken in adequate dosage. An understanding of the pathophysiology and aetiology of asthma is essential if full advantage is to be taken of the wide range of drugs now available for treating it. Airflow obstruction due to bronchial muscle constriction is usually readily reversible by bronchodilators, whereas that due to the inflammatory component of asthma is refractory to the latter and can only be reversed by steroids. Refractory airflow obstruction is liable to be confused with irreversible obstruction which occurs in those patients whose asthma is complicated by chronic obstructive bronchitis or other lung disease. The choice between symptomatic, preventive and suppressive forms of treatment should be made only after a careful assessment has been carried out with objective measurement of airflow obstruction. The Wright peak flow meter is unsurpassed for this purpose. By its means it should be possible to estimate how much of a patient's airflow obstruction is readily reversible, how much is refractory and how much is irreversible. In general, the aim of treatment is to relieve airflow obstruction rather than to counteract supposed aetiological factors. Both doctor and patient must understand the purpose, limitations and possible dangers of any drug which is prescribed. Steroids are the only form of treatment which is effective in persistent refractory asthma. Prejudice against steroids has resulted in many patients being deprived of their benefit, but this situation may change with the recent introduction of steroid aerosols.

Objectives Medical tourism involves patients’ intentional travel to privately obtain medical care in another country. Empirical evidence regarding health and safety risks facing medical tourists is limited. Consideration of this issue is dominated by speculation and lacks meaningful input from people with specific expertise in patient health and safety. We consulted with patient health and safety experts in the Canadian province of British Columbia to explore their views concerning risks that medical tourists may be exposed to. Herein, we report on the findings, linking them to existing ethical and legal issues associated with medical tourism. Design We held a focus group in September 2011 in Vancouver, British Columbia with professionals representing different domains of patient health and safety expertise. The focus group was transcribed verbatim and analysed thematically. Participants Seven professionals representing the domains of tissue banking, blood safety, health records, organ transplantation, dental care, clinical ethics and infection control participated. Results Five dominant health and safety risks for outbound medical tourists were identified by participants: (1) complications; (2) specific concerns regarding organ transplantation; (3) transmission of antibiotic-resistant organisms; (4) (dis)continuity of medical documentation and (5) (un)informed decision-making. Conclusions Concern was expressed that medical tourism might have unintended and undesired effects upon patients’ home healthcare systems. The individual choices of medical tourists could have significant public consequences if healthcare facilities in their home countries must expend resources treating postoperative complications. Participants also expressed concern that medical tourists returning home with infections, particularly antibiotic-resistant infections, could place others at risk of exposure to infections that are refractory to standard treatment regimens and thereby pose significant public health risks.

Treatment of relapsed/refractory acute myeloid or lymphoid leukemia consists of salvage chemotherapy followed by allogeneic hematopoietic stem-cell transplantation. Intravenous fludarabine, cytarabine, and filgrastim is an effective regimen in this setting. In view of the lack of availability of intravenous fludarabine in Mexico from 2009-2013, we substituted an equivalent oral fludarabine dose (40 mg) for the intravenous formulation. This is a retrospective comparison of the toxicity and effectiveness of oral fludarabine, cytarabine, and filgrastim versus intravenous fludarabine, cytarabine and filgrastim. A total of 44 patients with relapsed/refractory acute myeloid leukemia or acute lymphoid leukemia treated in an academic medical center from 2005-2013 with oral fludarabine, cytarabine and filgrastim (21 patients) or intravenous fludarabine, cytarabine and filgrastim (23 patients) were included in the analysis. There was a trend towards a higher complete remission rate and a longer overall survival following intravenous fludarabine, cytarabine, and filgrastim as compared with oral fludarabine, cytarabine, and filgrastim: complete remission rates 39.1 vs. 23.8% (p = 0.342) and overall survival 6.14 vs. 10.78 months (p = 0.363), respectively. A higher incidence of neutropenic fever (100 vs. 76.2%; p = 0.019) and septic shock (34.8 vs. 0%; p = 0.003) and a longer hospitalization (26.8 vs. 19.4 days; p = 0.046) were observed with intravenous fludarabine, cytarabine, and filgrastim. In multivariate analysis, factors associated with a shorter survival were septic shock (HR: 3.93; 95% CI: 1.67-9.25; p = 0.002) and a higher number of previous treatments (HR: 2.5; 95% CI: 1.26-4.99; p = 0.009). Complete remission was associated with better survival (HR: 0.18; 95% CI: 0.08-0.44; p < 0.001). Further studies are needed to determine the optimal dose and timing of oral fludarabine when given as part of the fludarabine, cytarabine, and filgrastim regimen for relapsed/refractory acute leukemia. Our data suggest that the dose of oral fludarabine used, 40 mg/m² per day for five days, may be a lower bioequivalent dose to the intravenous dose in fludarabine, cytarabine, and filgrastim.

Focal Dystonia in Hemiplegic Upper Limb: Favorable Effect of Cervical Microsurgical DREZotomy Involving the Ventral Horn - A Report of 3 Patients.

Focal dystonia in hemiplegic upper limbs is poorly responsive to medications or classical neurosurgical treatments. Only repeated botulinum toxin injections show efficacy, but in most severe cases effects are transient. Cervical DREZ lesioning, which has proven efficacious in hyperspasticity when done deeply (3-5 mm) in the dorsal horn, may have favorable effects on the dystonic component when performed down to, and including, the base of the ventral horn (5-6 mm in depth). Three patients underwent deep cervical microsurgical DREZotomy (MDT) for focal dystonia in the upper limb. Hypertonia was reduced, and sustained dystonic postures were suppressed. Residual motor function (hidden behind hypertonia) came to the surface. Cervical MDT may be a useful armamentarium for treating refractory focal dystonia in the upper limb. © 2016 S.

Pediatric Crohn disease is characterized by clinical and endoscopic relapses. The inflammatory process is considered to be progressive and may lead to strictures, fistulas, and penetrating disease that may require surgery. In addition, medically refractory disease may be treated by surgical resection of inflamed bowel in an effort to reverse growth failure. The need for surgery in childhood suggests severe disease and these patients have an increased risk for recurrent disease and potentially more surgery. Data show that up to 55% of patients had clinical recurrence in the first 2 years after initial surgery. The current clinical report on postoperative recurrence in pediatric Crohn disease reviews the risk factors for early surgery and postoperative recurrence, operative risk factors for recurrence, and prevention and monitoring strategies for postoperative recurrence. We also propose an algorithm for postoperative management in pediatric Crohn disease.

Summary Background: Hypothyroidism can usually be treated effectively by oral levothyroxine supplementation. There are, however, some rare circumstances, when oral levothyroxine application is not sufficient, for example malabsorption, interactions with food or other medications, or various gastrointestinal diseases. Case Report: We present a 42 year old woman with refractory and severe symptomatic hypothyroidism after subtotal thyroidectomy in spite of high dose oral levothyroxine supplementation. By stepwise increasing oral levothyroxine dosage up to 2200 micrograms plus 80 micrograms of thyronine, no sufficient substitution could be achieved. After suspicion of enteral malabsorption due to a pathological D-Xylose-test, subcutaneous levothyroxine supplementation was started. Finally, a sustained euthyroid state could be achieved. Conclusions: For selected patients who do not respond to oral treatment subcutaneous application of levothyroxine can be a suitable and effective therapy. PMID:23569562

Left ventricular assist devices (LVADs) have been used to treat advanced heart failure refractory to medical management, as bridge therapy to myocardial recovery, as bridge therapy to cardiac transplantation, or as destination therapy for patients with unfavorable transplant candidacy. Neurologic complications are some of the most common and devastating complications in these patients. Preoperative carotid ultrasound is, therefore, a standard evaluation in patients at risk for cerebrovascular disease. Postoperative carotid artery Doppler sonography is performed in those patients with neurologic symptoms. It is likely, therefore, that sonographers, radiologists, and other physicians working in a center where LVADs are implanted will likely encounter a carotid artery Doppler study in this patient group. To our knowledge, the carotid Doppler findings in these patients have never been published. We review the Doppler ultrasound findings in 6 patients after LVAD insertion.

Glutamic acid decarboxylase antibodies (GAD-Abs) have been implicated in refractory epilepsy. The association with refractory status epilepticus in adults has been rarely described. We discuss our experience in managing three adult patients who presented with refractory status epilepticus associated with GAD-Abs. Case series with retrospective chart and literature review. Three patients without pre-existing epilepsy who presented to our institution with generalized seizures between 2013 and 2014 were identified. Seizures proved refractory to first and second-line therapies and persisted beyond 24 hours. Patient 1 was a 22-year-old female who had elevated serum GAD-Ab titres at 0.49 mmol/l (normal: <0.02) and was treated with multiple immuno- and chemotherapies, with eventual partial seizure control. Patient 2 was a 61-year-old black female whose serum GAD-Ab titre was 0.08 mmol/l. EEG showed persistent generalized periodic discharges despite maximized therapy with anticonvulsants but no immunotherapy, resulting in withdrawal of care and discharge to nursing home. Patient 3 was a 50-year-old black female whose serum GAD-Ab titre was 0.08 mmol/l, and was discovered to have pulmonary sarcoidosis. Treatment with steroids and intravenous immunoglobulin resulted in seizure resolution. Due to the responsiveness to immunotherapy, there may be an association between GAD-Abs and refractory seizures, including refractory status epilepticus. Causation cannot be established since GAD-Abs may be elevated secondary to concurrent autoimmune diseases or formed de novo in response to GAD antigen exposure by neuronal injury. Based on this report and available literature, there may be a role for immuno- and chemotherapy in the management of refractory status epilepticus associated with GAD-Abs.

To analyze a case series of patients who underwent injection of industrial liquid silicone in a clandestine manner and by unauthorized persons. We conducted a retrospective analysis of medical records of patients treated between September 2003 and December 2010. Data regarding gender, age, location and volume of silicone injected, time between application and clinical manifestations, complications, treatment and outcome were collected. Early manifestations were defined as occurring within 30 days of injection and late manifestations, the ones arising after this period. We treated 12 patients, eight were male, seven transsexuals. The volume injected ranged from 5 ml to 2000 ml, being unknown in three cases. The most often used injected sites were the thighs and buttocks. Eight patients had early manifestations, with inflammation and/or infection. Surgical debridement was necessary in five cases. Three patients with a history of injection in the breast region underwent adenomastectomy. There was one death due to refractory septic shock. The use of industrial liquid silicone should be completely contraindicated as a filling material and modification of body contouring, and may have serious complications, even death.

A Case of Treatment Refractory Hyperemesis Gravidarum in a Patient with Comorbid Anxiety, Treated Successfully with Adjunctive Gabapentin

Hyperemesis gravidarum occurs in 0.3 to 10 percent of pregnant women, with a 0.8 percent hospital admission rate. While older theories supported the psychosocial model as a cause for hyperemesis gravidarum, more recent studies have shown significant data to support a biological etiology. Hyperemesis gravidarum has serious complications including include increased risk for miscarriage, low birth weight infants, dehydration, Wernicke’s encephalopathy, secondary depression, and negative attitudes toward a consecutive pregnancy. Because of these life-threatening complications and complexity of the disease, it is important to treat both somatic and psychosocial causes of hyperemesis gravidarum to provide the best care for the patient. This paper presents a case of a woman with anxiety symptoms who was experiencing severe nausea and vomiting since Week 2 of pregnancy, with minimal reduction of these symptoms on standard medications utilized in hyperemesis gravidarum. The patient had marked reduction of nausea and vomiting with adjunctive gabapentin. After a brief review of relevant neurogastroenterology, we discuss a possible mechanism for the added gabapentin.

Electroconvulsive therapy (ECT) has demonstrated efficacy in treating core symptoms of Parkinson's disease (PD); however, widespread use of ECT in PD has been limited due to concern over cognitive burden. We investigated the use of a newer ECT technology known to have fewer cognitive side effects (right unilateral [RUL] ultra-brief pulse [UBP]) for the treatment of medically refractory psychiatric dysfunction in PD. This open-label pilot study included 6 patients who were assessed in the motoric, cognitive, and neuropsychiatric domains prior to and after RUL UBP ECT. Primary endpoints were changes in total score on the HAM-D-17 and GDS-30 rating scales. Patients were found to improve in motoric and psychiatric domains following RUL UBP ECT without cognitive side effects, both immediately following ECT and at 1-month follow-up. This study demonstrates that RUL UBP ECT is safe, feasible, and potentially efficacious in treating multiple domains of PD, including motor and mood, without clear cognitive side effects. © 2016 John Wiley & Sons A/S.

Impulsivity and impaired decision-making have been proposed as obsessive-compulsive disorder (OCD) endophenotypes, running in OCD and their healthy relatives independently of symptom severity and medication status. Deep brain stimulation (DBS) targeting the ventral limb of the internal capsule (vALIC) and the nucleus accumbens (Nacc) is an effective treatment strategy for treatment-refractory OCD. The effectiveness of vALIC-DBS for OCD has been linked to its effects on a frontostriatal network that is also implicated in reward, impulse control, and decision-making. While vALIC-DBS has been shown to restore reward dysfunction in OCD patients, little is known about the effects of vALIC-DBS on impulsivity and decision-making. The aim of the study was to compare cognitive impulsivity and decision-making between OCD patients undergoing effective vALIC-DBS or treatment as usual (TAU), and healthy controls. We used decision-making performances under ambiguity on the Iowa Gambling Task and reflection impulsivity on the Beads Task to compare 20 OCD patients effectively treated with vALIC-DBS, 40 matched OCD patients undergoing effective TAU (medication and/or cognitive behavioural therapy), and 40 healthy subjects. Effective treatment was defined as at least 35% improvement of OCD symptoms. OCD patients, irrespective of treatment modality (DBS or TAU), showed increased reflection impulsivity and impaired decision-making compared to healthy controls. No differences were observed between OCD patients treated with DBS or TAU. OCD patients effectively treated with vALIC-DBS or TAU display increased reflection impulsivity and impaired decision-making independent of the type of treatment.

Refractory Cardiogenic Shock During Tramadol Poisoning: A Case Report.

PubMed

Belin, Nicolas; Clairet, Anne-Laure; Chocron, Sidney; Capellier, Gilles; Piton, Gaël

Tramadol is a weak opioid analgesic indicated for the treatment of moderate to severe pain. Tramadol intoxication can be lethal, and this drug is frequently involved in voluntary overdose. Classically, tramadol intoxication is associated with neurological and respiratory side effects. In contrast, cardiac effects are poorly documented in the literature. We report a case of severe tramadol intoxication, with plasma concentration 20 times the toxic threshold, complicated by refractory cardiogenic shock, successfully treated by extra corporeal life support (ECLS) with a favorable cardiac outcome and ECLS weaning at day 10. Seizure, clonus, and nonreactive mydriasis were present during 4 days, and complete awakening was delayed to day 15. Poisoning caused by high doses of tramadol can lead to refractory cardiogenic shock, and ECLS can be considered as effective rescue therapy in this context.

Burst suppression is actively studied as a control signal to guide anesthetic dosing in patients undergoing medically induced coma. The ability to automatically identify periods of EEG suppression and compactly summarize the depth of coma using the burst suppression probability (BSP) is crucial to effective and safe monitoring and control of medical coma. Current literature however does not explicitly account for the potential variation in burst suppression parameters across different scalp locations. In this study we analyzed standard 19-channel EEG recordings from 8 patients with refractory status epilepticus who underwent pharmacologically induced burst suppression as medical treatment for refractory seizures. We found that although burst suppression is generally considered a global phenomenon, BSP obtained using a previously validated algorithm varies systematically across different channels. A global representation of information from individual channels is proposed that takes into account the burst suppression characteristics recorded at multiple electrodes. BSP computed from this representative burst suppression pattern may be more resilient to noise and a better representation of the brain state of patients. Multichannel data integration may enhance the reliability of estimates of the depth of medical coma.

Recently, several medical treatments for ulcerative colitis (UC) have been developed, including 5-aminosalicylic acids (5-ASAs), corticosteroids, thiopurine, calcineurin inhibitors, and anti-tumor necrosis factor (TNF) α treatments. Treatment options including calcineurin inhibitors and anti-TNF treatment for refractory UC are discussed in this article. Furthermore, upcoming treatments are introduced, such as golimumab, vedolizumab, AJM300, tofacitinib. Budesonide foamwill be used as one treatment option in patients with distal colitis. Herbal medicine, such as Qing-Dai is also effective for active UC and may be useful for patients who are refractory to anti-TNFα treatments. In the near future, physicians will able to use many different treatments for UC patients. However, we should not forget 5-ASA and corticosteroids as the fundamental treatments for UC patients.

evaluate the efficacy of radiofrequency catheter ablation in patients with refractory cardiac arrhythmias. twenty patients with refractory cardiac arrhythmias were undertaken to electrophysiologic studies for diagnosis and radiofrequency catheter ablation of their reentrant arrhythmias. Ten patients were men and 10 women with ages varying from 13 to 76 years (mean = 42.4 years). Nineteen patients had supraventricular tachyarrhythmias: One patient had atrial tachycardia and 1 atrial fibrillation with rapid ventricular rate, 5 patients had reentrant nodal tachycardia, 12 patients had reentrant atrioventricular tachycardia and 1 patient had right ventricular outflow tract tachycardia. the mean time of the procedure was 4.1 hours. The radiofrequency current energy applied was 40-50 V for 30-40 seconds. Ablation was successful in 18/20 (90%) patients; in 15/18 (83%) of successfully treated patients the same study was done for diagnosis and radiofrequency ablation. One patient had femoral arterial occlusion and was treated with no significant sequelae. During a mean follow-up of 4 months no preexcitation or reentrant tachycardia occurred. the results of our experience with radiofrequency catheter ablation of cardiac arrhythmias suggest that this technique can benefit an important number of patients with cardiac arrhythmias.

Local progression, in patients with hormone-refractory prostate cancer, often causes significant morbidity. Pelvic radiotherapy (RT) provides effective palliation in this setting, with most published studies supporting the use of high-dose regimens. The aim of the present study was to examine the role of split-course hypofractionated RT used at our institution in treating this group of patients. A total of 34 men with locoregionally progressive hormone-refractory prostate cancer, treated with a split course of pelvic RT (45-60 Gy in 18-24 fractions) between 2000 and 2008 were analyzed. The primary endpoints were the response rate and actuarial locoregional progression-free survival. Secondary endpoints included overall survival, compliance, and acute and late toxicity. The median age was 71 years (range, 53-88). Treatment resulted in an overall initial response rate of 91%, a median locoregional progression-free survival of 43 months, and median overall survival of 28 months. Compliance was excellent and no significant late toxicity was reported. The split course pelvic RT described has an acceptable toxicity profile, is effective, and compares well with other high-dose palliative regimens that have been previously reported.
