Treatment of trigeminal neuralgia: role of radiofrequency ablation
Trigeminal neuralgia (TN) is a neuropathic pain condition affecting the face. It has a significant impact on the quality of life and physical function of patients. Evidence suggests that the likely etiology is vascular compression of the trigeminal nerve leading to focal demyelination and aberrant neural discharge. Secondary causes such as multiple sclerosis or brain tumors can also produce symptomatic TN. Treatment must be individualized to each patient. Carbamazepine remains the drug of choice in the first-line treatment of TN. Minimally invasive interventional pain therapies and surgery are possible options when drug therapy fails. Younger patients may benefit from microvascular decompression. Elderly patients with poor surgical risk may be more suitable for percutaneous trigeminal nerve rhizolysis. The technique of radiofrequency rhizolysis of the trigeminal nerve is described in detail in this review
Practice advisory on the appropriate use of NSAIDs in primary care
Cyclo-oxygenase (COX)-2 selective and nonselective nonsteroidal anti-inflammatory drugs (NSAIDs) are important in managing acute and chronic pain secondary to inflammation. As a greater understanding of the risks of gastrointestinal (GI), cardiovascular (CV) and renal events with NSAIDs use has emerged, guidelines have evolved to reflect differences in risks among NSAIDs. Updated guidelines have yet to reflect new evidence from recent trials which showed similar CV event rates with celecoxib compared to naproxen and ibuprofen, and significantly better GI tolerability for celecoxib. This practice advisory paper aims to present consensus statements and associated guidance regarding appropriate NSAID use based on a review of current evidence by a multidisciplinary group of expert clinicians. This paper is especially intended to guide primary care practitioners within Asia in the appropriate use of NSAIDs in primary care. Following a literature review, group members used a modified Delphi consensus process to determine agreement with selected recommendations. Agreement with a statement by 75% of total voting members was defined a priori as consensus. For low GI risk patients, any nonselective NSAID plus proton pump inhibitor (PPI) or celecoxib alone is acceptable treatment when CV risk is low; for high CV risk patients, low-dose celecoxib or naproxen plus PPI is appropriate. For high GI risk patients, celecoxib plus PPI is acceptable for low CV risk patients; low-dose celecoxib plus PPI is appropriate for high CV risk patients, with the alternative to avoid NSAIDs and consider opioids instead. Appropriate NSAID prescription assumes that the patient has normal renal function at commencement, with ongoing monitoring recommended. In conclusion, appropriate NSAID use requires consideration of all risks
Pneumococcal conjugate vaccine implementation in middle-income countries
Since 2000, the widespread adoption of pneumococcal conjugate vaccines (PCVs) has had a major impact in the prevention of pneumonia. Limited access to international financial support means some middle-income countries (MICs) are trailing in the widespread use of PCVs. We review the status of PCV implementation, and discuss any needs and gaps related to low levels of PCV implementation in MICs, with analysis of possible solutions to strengthen the PCV implementation process in MICs
Dominância fiscal : uma investigação empírica sobre o caso brasileiro no período de 2003 a 2014
A estabilização econômica dos anos de 1990 e a adoção do tripé econômico, a partir de
1999, marcam o fim de um capítulo delicado da história brasileira; a partir de então, era
necessária a existência de certa sintonia de políticas monetária e fiscal para a
manutenção do controle dos diversos indicadores econômicos. Contudo, com essa
reciprocidade na política econômica, são incitadas discussões sobre a orientação do
governo na hora de definir suas prioridades nesse campo: as variáveis fiscais são
priorizadas e, por conseguinte, determinadas, forçando as monetárias a se ajustarem –
ou o contrário? A resposta para esse questionamento leva à discussão sobre a
dominância fiscal. Assim, esse trabalho visa verificar empiricamente, usando das
modelagens econométricas VAR e estudo de eventos, se há dominância fiscal ou
monetária na economia brasileira e se a eficácia da política monetária mudou na
transição do governo Lula para o governo Dilma. O resultado foi inconclusivo para o
governo Lula e indicou dominância fiscal no governo Dilma. Ainda verificou-se não
haver modificação na eficácia da política monetária.Economic stabilization, in the 1990s, and utilization of an economic tripod, after 1999,
represents the end of a delicate chapter in Brazilian history. Ever since, it was necessary
the existence of a certain agreement between monetary and fiscal politic, in order to
maintain under control a variety of economic indicators. However, this reciprocity (in
economic politic) starts discussions about the real government orientations when it
comes to define its priority on this subject: are the fiscal variables priorized, and then,
determined, forcing monetary variables to adjust themselves, or the opposite? The
answer to these questions emerge from the fiscal dominance discussion. This paper
intends to empiric verify, using econometric modeling VAR and event study, if there is
fiscal dominance or monetary in Brazilian economy and whether the effectiveness of
monetary politic has changed in the transition from Lula's government to the Dilma
government. The result was inconclusive for the Lula government and indicated fiscal
dominance in the Dilma government. There was still no change in the efficiency of the
monetary politic.CAPE

Spinal Cord Stimulation for the Treatment of Intractable Pain from Failed Back Surgery Syndrome
Introduction: Failed back surgery syndrome (FBSS) is a debilitating chronic neuropathic pain condition, affecting approximately 10–40% of patients after lumbosacral spine surgery. Treatment of FBSS is challenging as conservative therapies and repeat surgery often fail in providing adequate pain relief. Spinal cord stimulation (SCS) has been proven to be a successful therapeutic option in FBSS patients. Case Report: A 23 year-old male presented with persistent low back pain and bilateral radicular pain after spinal surgery. He was also wheelchair-bound because of his severe pain. Conservative treatment with oral analgesics and interventional pain procedures were unsuccessful in improving his pain. Subsequently, we performed a permanent implantation of epidural leads for SCS after a successful trial of SCS. He reported good coverage of pain without complications after the procedure. Three months after surgery, and after intensive physiotherapy and rehabilitation, he could walk and return to work. Conclusion: We describe our first successful case of treating intractable pain from FBSS in a patient after implantation of SCS leads in our institution
Cooled radiofrequency denervation for treatment of sacroiliac joint pain: two-year results from 20 cases
Sacroiliac joint pain is a common cause of chronic low back pain. Different techniques for radiofrequency denervation of the sacroiliac joint have been used to treat this condition. However, results have been inconsistent because the variable sensory supply to the sacroiliac joint is difficult to disrupt completely using conventional radiofrequency. Cooled radiofrequency is a novel technique that uses internally cooled radiofrequency probes to enlarge lesion size, thereby increasing the chance of completely denervating the sacroiliac joint. The objective of this study was to evaluate the efficacy of cooled radiofrequency denervation using the SInergy™ cooled radiofrequency system for sacroiliac joint pain
Intrathecal analgesia in patients with cancer pain--an audit in a tertiary institution
Cancer pain is one of the most frequently encountered pain syndromes. With the application of the World Health Organization analgesic ladder, adequate analgesia is achieved in 75% to 90% of patients. The remaining patients suffer from intractable pain requiring intrathecal
analgesia. The aim of this study was to retrospectively analyse the pain intensity before and after intrathecal analgesia and review the complications associated with the implantation and the care of the intrathecal device. Materials and Methods: We reviewed medical records
of all cancer patients whose pain were managed by intrathecal catheter implants in our centre from February 2005 to August 2008. The pain intensity, medication and complications related to intrathecal catheter insertion or drug delivery were reviewed at the time before starting the
intrathecal analgesia (T0) and time of discharge from the hospital/time prior to death during their stay in the hospital (Tdsc). Results: Twenty-nine patients were included. Out of these 29 patients, 86.2% had metastatic cancer. The most common indication was poor pain control.
Pain intensity was reduced signifi cantly at the time of discharge from hospital (P <0.001). The number of patients with side effects from opioids decreased after intrathecal treatment. We found 4 patients with short-term catheter complications e.g. kinked or displaced catheter and
catheter-related infection. Conclusion: Intractable cancer pain could be managed effectively by intrathecal analgesia with a signifi cant decrease in pain intensity and reduced opioid-related side effects. The side effects due to intrathecal opioids and complications from intrathecal
catheter were minimal
