OnabotulinumtoxinA Nerve Blocks in the Treatment of Occipital Neuralgia  [PDF]
Andrew Ea, Terence Gray
Pain Studies and Treatment (PST) , 2016, DOI: 10.4236/pst.2016.43005
Abstract: Occipital neuralgia is characterized by severe pain, accompanied by tenderness and trigger points, in the distribution of the greater, lesser, and/or third occipital nerves. Occipital neuralgia is typically idiopathic, but also is characterized as a common form of posttraumatic headache. Typical treatments include nerve blocks with local anesthetic, nerve stimulation, pulsed radiofrequency, and cryoablation. OnabotulinumtoxinA (ONA) has recently been utilized in nerve blocks to treat occipital neuralgia, with the potential for a longer duration of pain relief than local anesthetic. Our study retrospectively examined 63 patients treated for occipital neuralgia, including 19 with ONA. 80 - 155 units of ONA were administered bilaterally in the surrounding musculature. A total of 61 patients, including 17 of those subsequently treated with ONA, were treated with local anesthetic, using a 1:1 mixture of 0.25% bupivacaine and 1% lidocaine, plus triamcinolone. Patients reported VAS pain scores before and after their procedures, and again during 4-week follow-up visits. Information on opioid use, overall pain relief, and duration of full relief was also recorded upon follow-up. Patients treated with ONA exhibited significant decreases in average VAS pain scores from 4.1 ± 2.6 pre-procedure to 2.1 ± 2.4 post-procedure (p = 2 × 10 -5), and 3.0 ± 2.5 4 weeks later (p = 0.0234). Mean overall relief was 75.8% ± 25.0%. Treatment with local anesthetic suggested equally efficacious reduction of VAS scores; however, treatment with ONA showed a significantly higher percentage of overall pain relief leading to follow-up. Opioid use did not exhibit significant change, regardless of treatment type. Our results support the hypothesis that use of Onabotulinum-toxinA in occipital nerve blocks leads to significant decreases in pain, while possibly exhibiting a longer duration of action than that of local anesthetic.
OnabotulinumtoxinA in the Treatment of Occipital Neuralgia Following Gunshot Injury  [PDF]
Andrew Ea, Terence Gray
Pain Studies and Treatment (PST) , 2016, DOI: 10.4236/pst.2016.44007
Abstract: Occipital neuralgia, while typically idiopathic in presentation, is a common form of posttraumatic headache. It is associated with severe pain in the greater, lesser, and/or third occipital nerves, and often accompanied by tenderness or trigger points in the surrounding musculature. OnabotulinumtoxinA (ONA) has been recently utilized in nerve blocks to treat occipital neuralgia, but current literature supporting such use is scarce. We describe a case of occipital neuralgia in a patient following C1 fracture and vertebral artery dissection due to gunshot injury. Successful treatment with bilateral ONA nerve blocks led to an 80% - 90% improvement in pain, with decreased Visual Analog Scale (VAS) pain scores immediately following treatment and upon follow-up 1 month later.

International Journal of Health Geographics , 2008, DOI: 10.1186/1476-072x-7-55
Abstract: A total of 4,160 cases of malaria were recorded in 14 Indian reserves in the State of Rond?nia between 2003 and 2006. In six reservations no cases of malaria were reported in the period. Overall, P. vivax accounted for 76.18 of malaria cases reported in the indigenous population of Rond?nia. The P. vivax/P. falciparum ratio for the period was 3.78. Two reserves accounted for over half of the cases reported for the total indigenous population in the period – Roosevelt and Pacaas Novas – with a total of 1,646 (39.57%) and 1,145 (27.52%) cases, respectively. Kernel mapping of malaria mean Annual Parasite Index – API according to indigenous reserves and environmental zones revealed a heterogeneous pattern of disease distribution, with one clear area of high risk of transmission comprising reservations of west Rond?nia along the Guaporé-Madeira River basins, and another high risk area to the east, on the Roosevelt reserve.By means of kernel mapping, it was shown that malaria risk varies widely between Indian reserves and environmental zones defined on the basis of predominant ecologic characteristics and land use patterns observed in the southwestern Brazilian Amazon. The geographical approach in this paper helped to determine where the greatest needs lie for more intensively focused malaria control activities in Indian reserves in the region. It also provided a reference to assess the effectiveness of control measures that have been put in place by Brazilian public health authorities.Malaria is recognized as a major cause of morbidity in Brazil. The Amazon region, which represents approximately 60% of the national territory, accounts for nearly 99% of all cases in the country. During the 1990s more than 600,000 cases were reported annually [1,2]. In spite of the relative success of efforts to control malaria over the last decades, the disease remains an important cause of morbidity in the Brazilian Amazon, with an estimated 6 million people considered at high risk of ma

Nutrition Journal , 2012, DOI: 10.1186/1475-2891-11-3
Abstract: A cross-sectional study was conducted in July 2006 that included all children under the age of 10 from the Xavante village Pimentel Barbosa in Mato Grosso, Brazil. The data collected included weight, height, and sociodemographic information. Sociodemographic data were used to generate two indices ("income" and "wealth") and to determine the proportion of adults in each household. Descriptive analyses were performed for weight-for-age (W/A), height-for-age (H/A), and weight-for-height (W/H) using the NCHS and the WHO growth references. Univariate and multivariate analyses were conducted using H/A and W/A as a response variables.Of a total of 246 children under the age of ten residing in the village, 232 (94.3%) were evaluated. Following the NCHS reference, 5.6% of children under the age of ten presented low W/A and 14.7% presented low H/A. Among children under the age of five, deficit percentages for weight and height were 4.5% and 29.9%, respectively, following the WHO curves. Among children < 2 years of age, H/A index variability was found to be directly related to child's age and inversely related to the proportion of adults in the household. Maternal BMI was positively associated with growth for children from 2 to 4 years of age, explaining 11.5% of the z-score variability for the H/A index. For children 5 years of age and older, the wealth index and maternal height were positively associated with H/A. No significant associations were found using W/A as the dependent variable.This study demonstrated that undernutrition, in particular linear growth deficit, is a notable health issue for Xavante children. These findings contrast with the nutritional profile observed among Brazilian children nationally, which is characterized by a sharp decline in child undernutrition in recent decades, even in the poorest regions of the country. This discrepancy calls attention to the persistent health disparities that exist between indigenous and non-indigenous people in Brazil.Ra

Gender and Topicality in Onwueme’s Plays
EA Nyager
African Research Review , 2011,
Abstract: Gender discourse as an offshoot of feminism has become an important factor in the global discourse on development. As a feminist, Tess Onwueme has often high-lighted her discussion of topical, national and global issues against the metaphorical backdrop of women exploited and disfranchised but identifiable with the nation/state. This paper seeks to illustrate the discussions of gender and topical/national issues through a focused examination of one or two of Onwueme’s plays, namely: What Mama Said and No Vacancy. This will by no means limit our referencing to any other of her works. By this examination we also seek to present the playwright as a committed sensitive and creative artist who speaks for and seeks to lend voice to the voiceless.
Rheumatic Heart Disease Associated with Secondary Renal Amyloidosis
EA Abdallah
Arab Journal of Nephrology and Transplantation , 2012,
Abstract: Introduction: Amyloidosis is a disorder of protein folding in which normally soluble proteins undergo conformational changes and are deposited in the extracellular space in an abnormal fibrillar form. Accumulation of these fibrils causes progressive disruption of the structure and function of tissues and organs, and the systemic forms of amyloidosis are frequently fatal. The conditions that underlie amyloid deposition may be either acquired or hereditary. Amyloid-A (AA) amyloidosis is the most common form of systemic amyloidosis worldwide, AA amyloidosis occurs in the course of chronic inflammatory diseases, hereditary periodic fevers, and with certain neoplasms such as Hodgkin disease and renal cell carcinoma. Amyloidosis due to rheumatic heart disease (RHD) is not common but can be seen. We report here a patient with RHD and AA renal amyloidosis. Case Report: we present a 30 year-old Egyptian male with a history of RHD, accidently discovered to have nephrotic range proteinuria and rising serum creatinine. Serology studies were negative or normal, including antinuclear antibody (ANA) and antineutrophil cytoplasmic antibody (ANCA). C3 and C4 complement levels were normal. Kidney biopsy revealed AA renal amyloidosis. CT chest and abdomen revealed bilateral hilar and mediastinal lymphadenopathy and para-aortic lymph nodes. Endobronchial biopsy and bronchoalveolar lavage revealed non-specific chronic inflammatory changes. The patient’s secondary amyloidosis was presumed to be related to the long standing RHD after exclusion of other causes of secondary amyloidosis. The patient finally died due to heart failure and acute pulmonary edema. Conclusion: Long standing RHD can lead to secondary AA amyloidosis.
Transformational Relations as Elegant Variation in Writing
EA Chukwu
African Research Review , 2010,
Abstract: Transformational relations or relations of grammatical paraphrase describecontrasting syntactic structures possessing the same referential object andexpressing the same sense. The grammatical category, voice, exemplifiestransformations through its streamlined active-passive constructions. Thepredominance of the active expression makes many budding scholarsignorant of the alternative passivization. The formation of transformations,the verbs involved in transformation, the reasons for adopting passiveconstructions, the relevance of the expressions in fields of discourse areelucidated in detail as requisite skills for writing and speaking competently.In addition, transformational relations as sentential synonymy examinesentences with different structural frameworks as synonymous for embracingthe same truth conditions: the same referent, the same sense or meaning, and the same event in the real world. Generally, sentences that have the same necessary and sufficient conditions for determining their truth or falsity are paraphrase.
Parallelism: A Semiotic Feature of Belle Lettres
EA Chukwu
African Research Review , 2010,
Abstract: Parallelism as an expressive feature embellishes graces and endears the well-formedness of sentences elucidating writings and speeches. This paper therefore reintroduces a fundamental feature making utterances rhythmical, rhetorical and elocutionary, qualities severally being misused, overlooked and misinterpreted by many learners, many teachers, and many writers (journalists). It is with regard to the near-neglect of this veritable writing technique that this paper expatiates the concepts of parallelism, the interface between belle lettres (beautiful letters or writings) and belle-lettres (literary writings or studies), and parallelism as a semiotic element of syntactics. It as well juxtaposes well-formed parallel structures and ill-formed ones as exemplary indications of dos and don’ts of making speeches or composing essays. The paper unequivocally underlines the sine qua non of parallelism before effective and enduring speeches and writings can be accomplished.
El Greco’s Italian paintings (1560-76) based on Bible texts
EA Maré
Acta Theologica , 2009,
Abstract: The purpose of this article is to interpret a selection of El Greco’s Italian paintings (1560-1576) based on Bible texts in which ideas current during the Catholic Counter-Reformation are symbolised. At the age of nineteen El Greco, who was born in Crete in 1541 and was initially an icon painter in the Byzantine tradition, went to Venice. Through study and experiment, and by following the examples of other artists who had achieved artistic mastery and was of proven Catholic orthodoxy, he educated himself as an artist in the Western manner. Even during his years as an apprentice El Greco’s art is proof that he aspired to the highest humanly accessible values exemplified by Renaissance artistic theory, humanism and Christian spirituality — all of which later came to fruition in an unprecedented original combination in Toledo, Spain, where he settled permanently in 1577.
