Inclusão educacional de crianças com deficiências: notas do chão da escola
Authors: Freitas Marcos Cezar de , Jacob Rosângela Nezeiro da Fonseca
Published: March 2019

Resumo O tema deste artigo é a inclusão de crianças com deficiência na educação pública. O problema de pesquisa apresentado tem origem nos debates sobre a vida escolar inclusiva e diz respeito às situações concretas que foram analisadas no cotidiano de duas escolas. O objetivo principal foi acompanhar o acesso de crianças em cujo registro de matrícula são mencionadas deficiência múltipla ou paralisia cerebral. Desse objetivo, foi organizada a estratégia de observar os diferentes modos de participação e registrar, para análise em detalhes, as cenas em que o acesso não conduziu a uma vida escolar inclusiva e as cenas que, em sentido oposto, revelaram uma dinâmica de participação que resultou em procedimentos inclusivos. Metodologicamente, a coleta de informações, o registro em cadernos de campo e as muitas horas de observação resultaram de etnografias realizadas a partir de 2014 nas escolas públicas identificadas previamente para a pesquisa. Referências antropológicas foram utilizadas. Os principais resultados foram obtidos com inventários de gestos e procedimentos recolhidos em escala microscópica, que indicaram haver dependência entre estratégias inclusivas e abordagens com foco no trabalho pedagógico como um todo e para todos os alunos. Quando a abordagem restringiu-se ao isolamento das crianças para evitar que suas particularidades atrapalhassem os demais, o acesso claramente não ofereceu um modo de participar compatível com uma vida escolar inclusiva. O texto apresenta, em suas conclusões, uma análise sobre as cenas focadas e, com base na pesquisa feita, sustenta que acesso nem sempre resulta em inclusão.
Concepções sobre os fatores, funções e problemas da aprendizagem do desenho artístico em estudantes universitários
Authors: Freire Luiz Gustavo , Duarte António Manuel
Published: March 2019

Resumo Este artigo expõe parte dos resultados de uma investigação que teve como objetivo explorar as concepções de aprendizagem do desenho artístico de estudantes universitários brasileiros, à luz da perspectiva fenomenográfica. Entre outras dimensões, um grupo de dezesseis estudantes de uma disciplina livre de desenho, dos cursos de Matemática, Ciências biológicas e Letras, foi entrevistado com base num guia de entrevista semiestruturada acerca das suas concepções sobre os fatores, as funções e os problemas da aprendizagem do desenho artístico. As respostas às entrevistas foram submetidas a uma análise de conteúdo temática, que implicou três fases: segmentação das respostas em unidades a categorizar, desenvolvimento e aplicação de um sistema de categorias de análise e exploração das categorias encontradas. Os resultados evidenciam uma ampla diferenciação de representações quanto aos fatores (isto é, a aprendizagem do desenho é influenciada por fatores afetivos, cognitivos, experienciais, problemáticos, pessoais indiferenciados e contextuais), às funções (isto é, a aprendizagem do desenho tem a função de desenvolvimento artístico, profissionalizante, afetiva, cognitiva e interpessoal), e aos problemas (isto é, a aprendizagem do desenho é afetada por problemas estruturais, de experiência, afetivos, cognitivos, interpessoais e contextuais). Essas representações são aqui interpretadas e apresentadas como utilizáveis para a compreensão e a melhoria do sucesso e da qualidade da aprendizagem na área do desenho artístico.
NASA Robotic Mining Competition
Authors: Buchmann Tim J
Published: March 2019

The skyâ€™s the limit, so the saying goes, yet humankind is trying to make a footprint on our neighbor Mars. Because of Mars distance from Earth, NASA would like to develop a mechanism to help astronauts to collect water crystals found below the sandy Martian regolith. As a result, they task the Robotic Mining Competition (RMC) teams to design a robot that can steer through a simulated Martian terrain, collect gravel (simulated water crystals) located under the regolith material (BP-1), and bring the gravel back to the collection bin. The RMC teams must work cooperatively in order to design and build such a robot, and to out-compete all their competitors. New solutions are being developed from colleges and universities all over the country to discover new mechanisms that can collect water crystals through a mining robot. These students have taken their skills from their schools, their internships, and clubs to apply their theory and design to develop these new mechanisms. From this program, these students created outreach programs to encourage science, technology, engineering, and mathematics to local communities by volunteering through mentorship programs and after-school activities.
Decoding Encoded Yorùbá Nomenclature: An Exercise of Linguistic Competence and Performance
Authors: Dalamu Taofeek Olaiwola
Published: March 2019

The study investigated word formation experience in Yorùbá names. At the deployment of ellipsis, as the instrument of analysis, one observed the effectiveness of terminologies of competence and performance, being operational in the clipping of statements to nominal lexemes, illustrated with names of ten towns in South West Nigeria. The study exhibited flexibility in the development of Yorùbá, which depended largely on users’ needs. Historical facts of business, religion, hunting, war and conquest supported the formations, without seemingly consistent linguistic principles. Eliminations of linguistic components occurred to the statements and sometimes with twists in pronunciations, displaying new lexemes and meanings. Although, individuals might attempt to regulate ways that people employ language to formulate words, the study suggested that language communicators should be allowed to deploy language as pleased. As language analyses seem descriptive, utilizing language as delighted might yield novel items to enhance language development in unique forms.
The Younger, the Better? A Multi-Factorial Approach to Understanding Age Effects on EFL Phonological Attainment
Authors: Pei Zhengwei , Qin Kerong
Published: March 2019

Second language (L2) phonological acquisition is constrained by a complex interplay of extra-linguistic factors, among which the age factor is frequently investigated. This study adopted a multi-factorial approach to examine the effects of the age of learning English (AoLE), along with ten other extra-linguistic factors, on the ultimate English phonological attainment of 318 university students in Chinese context for English as a foreign language (EFL) as a whole and across three cohorts: first-year non-English majors, first-year English majors, and third-year English majors. The participants were administered background questionnaires and receptive and productive EFL phonology tests. The results of regression analyses indicated that the AoLE was not a predictor for the whole sample, while English pronunciation self-concept (EPSC) turned out to be the most predictive. Predictors for each cohort varied in number and content. Whichever cohort the participants came from, EPSC remained a constant and potent predictor, whereas the AoLE could merely predict the phonological attainment of first-year non-English majors, accounting for 4% of its variance. The findings of the study contribute to the long-standing debate over the viability of the critical period hypothesis, provide methodological implications for age-related L2 phonology research, and inform early EFL educational decisions.

Published: March 2019

El Queso Crema de Chiapas (QCC) está caracterizado por ser artesanal y típico del Sur de México. Los recursos locales y el saber hacer fortalecen su producción y conservan sus características. Estudios previos han caracterizado el producto, no así la adopción de innovaciones en la agroindustria. El objetivo de esta investigación fue medir la adopción de innovaciones y posición competitiva de las agroindustrias y proponer alternativas de mejora. Como estudio de caso, se seleccionaron once (11) queserías del municipio de Pijijiapan en Chiapas, debido a que son las de mayor colaboración y representativas; se seleccionaron empresas organizadas dentro de la marca colectiva y empresas no organizadas. Se clasificaron en cuatro estratos mediante un análisis jerárquico y la posición competitiva se obtuvo con el análisis de componentes principales (ACP). La adopción de innovaciones para el estrato 1 fue de 49 % y de 18 % para el 4. Con respecto al ACP, dos componentes explican el 70 % de la variabilidad (KMO = 0.50; P < 0.05). La relación beneficio/costo fue de 1.14 para el estrato mejor posicionado y de 1.17 para el menor, si bien es mayor la relación para el estrato 4, en términos monetarios el 1 obtiene mayor utilidad. Se mostró mayor adopción de innovaciones en el estrato 1 quién tiene mayor utilidad y mejor posición competitiva, mientras que las menos competitivas presentan bajos e incluso nulos niveles de adopción en asistencia técnica y administración. La mejor posición competitiva se atribuye a implementación de innovaciones de mercado y administrativas adecuadas.

Published: March 2019

Combined traumatic injuries of the anterior eye segment are attributed to the severe consequences of the injured organ of vision. Iris defects result in spherical and chromatic aberrations, diplopia, flares, severe photophobia, cosmetic defects, and significantly reduced visual acuity after the injury. The literature describes various methods to restore visual functions impaired as a result of aniridia. Use of an artificial iris together with an intraocular lens pathology results in optimal reconstruction and recovery of normal anterior segment anatomy and topography. In this paper, we provide a report on a patient followed up for 15 years after combined reconstruction eye surgery for an off-the-job penetrating eye injury sustained in 2003. A complex intervention was required due to the involvement of the cornea, iris, and lens. In 2004, the patient underwent a lens-iris diaphragm implantation combined with penetrating keratoplasty. The diaphragm implantation was followed by an improvement in visual acuity and elimination of photophobia and flares. There were no intra- or postoperative complications. Two years later, LASIK refractive surgery was performed on the corneal transplant to eliminate induced ametropia. The patient retained good eye function, with a stable position of the lens-iris diaphragm, for many years after the diaphragm implantation, keratoplasty, and refractive surgery. In 2018, he had an intravitreal implant impregnated with dexamethasone, as changes in the retina had developed. The long-term follow-up in this case demonstrates that the implantation of a lens-iris diaphragm resulted in an elimination of undesirable optical events associated with aniridia and produced an optimal functional result, while also improving the patient’s quality of life with a good aesthetic effect.

Published: March 2019

A clinical case of chronic postoperative endophthalmitis treatment after cataract phacoemulsification is described in the article. The patient received vitrectomy with lens posterior capsule discission and tamponade of vitreal cavity by perfluororganic compound (up to 14 days) and 1mg vancomicin +2.25 mg ceftazidim intravitreally, also anterior chamber washing by 0.5 ml saline containing 5 mg vancomicin. Anterior chamber washing by antibiotics and intravitreal injection of antibacterial  medicine combination was repeated on the second and third day after the surgery. This tactics of treatment allowed to save lens capsular bag and intraocular lens. Purpose. To assess efficacy and safety of new treatment method in the patient with chronic postoperative endophthalmitis. Patient B, 65 years old applied to clinic with complaints on the pain in the right eye, visual acuity decrease up to finger counting near face. Symptoms started to disturb in 2 weeks after cataract extraction with IOL implantation. During 6 months courses of antibacterial therapy including vancomicin (antibiotic of reserve) there were no positive dynamics. Cornea edema, multiple precipitates at endothelium and intraocular lens were defined at biomicroscopy; 2.5 mm hypopyon in anterior camera; fibrin in pupil projection; exudation in vitreous cavity. Laser tyndalmetry data (albumen flow in anterior chamber) confirmed inflammation strong enough — 173 f/ms. Surgical treatment according the described method was rendered to the patient. In the postoperative period we saw stable visual functions, uncorrected visual acuity was 0.6, corrected — 0.8. Patient noted the absence of pain and eye’s reddening decrease. At biomicroscopy we observed considerable inflammation decrease, almost total absence of precipitates at cornea endothelium. Laser tyndalmetry data confirmed inflammation decrease, albumen flow in anterior chamber was 17.6 f/ms. Endothelial cells’ loss after surgery was 142 cells/1 mm2 (5.61 %). According to electrophysiologic investigation and ERG there was no deviation from normal values was revealed. This treatment method allows to restore visual functions rather quickly and can be used in  case of inefficient lengthy conservative therapy.

Published: March 2019

Purpose: to study the possibilities of complex ultrasound examination in the assessment of hemodynamic and structural features of retinal capillary hemangioma (RCH).Patients and methods. 26 patients (35 eyes) with RCHs at the age of 11 to 53 years (mean 26.6 ± 9.4 years) were examined. Ultrasound examination was performed using B–mode image, echodensitometry, Color Doppler Imaging (CDI) and pulsed Doppler (PD). The peak systolic velocity (Vsyst), the end-diastolic velocity (Vdiast) of the blood flow, and the resistance index (RI) in the orbital vessels were examined using CDI and PD. Qualitative and quantitative assessment of blood flow in a feeding artery and a draining vein of the RCHs were performed. The follow-up efficiency evaluation of the laser coagulation of RCH was performed in 12 eyes.Results. The elevation of RCH was 1.7 ± 0.7 mm (from 0.5 to 3.3 mm) on average, the base diameter — 5.4 ± 2.1 mm (from 1.8 to 11.5 mm). The acoustic density varied from 42 to 176 (mean 109.6 ± 30.9) in relative units. The indices of Vsyst were from 5.5 to 21.4 cm/s (mean value — 10.6 ± 4.2 cm/s) in the feeding arteries, from 3.06 to 14.3 cm/s — in veins (mean value — 4.9 ± 2.4 cm/s). A significant increase in the blood flow velocity in the central retinal vein (CRV), a decrease in RI in the central retinal artery (CRA) and short posterior ciliary arteries (SPCAs) were determined. In 3 (8.6 %) eyes, in the absence of echographic manifestations of small RCHs of optic nerve head (ONH), there was an increase of the blood flow velocity in the CRV (the mean value was 8.95 ± 1.15 cm/s). After treatment, B-scan ultrasonogram showed no visualization of RCHs in 3 eyes. A significant decrease (31 %) of prominence compared to the baseline values was registered in 9 eyes (66.7 %). A decrease of the tumor base the diameter by an average of 37.7 % was also registered in 7 eyes (58.3 %). A significant decrease (26.3 %) in Vsyst in arterial-type feeding vessels was determined.Conclusion. Significant changes in regional ocular blood flow in RCH were registered. The increase of blood flow in the CRV at the localization of RCH on the ONH can be an additional differential diagnostic criterion of the disease. The hemodynamic instability in the retinal vessels feeding the RCH and the positive dynamics of the blood flow after laser coagulation were determined.

Published: March 2019

Purpose. To study the dynamics of electrophysiological parameters of the retina and optic nerve after vitrectomy for a primary fullthickness macular hole.Patients and Methods. Electrophysiological examination was performed in 40 patients (40 eyes) before vitrectomy, on the 1st, 3rd, 7th, 14th, 30th, 60th, 180th day after the operation. Three groups of patients were formed depending on the intraocular tamponade: the first group — air tamponade, the second group — gas (C3F8) tamponade, the third group — silicone oil tamponade.Results. In the first, second and third groups significant decrease in the retinal and optic nerve electrogenesis was revealed on the 1st day (p < 0.001) after vitrectomy. By the end of observation period all electrophysiological indices in the first, second and third groups recover to normal levels, excluding the retinal cone system and optic nerve parameters in the third group. Electrophysiological indices recovered twice as slow in the second group, compared to the first group, due to C3F8 gas tamponade inhibitory effect. In the first and second groups the photoreceptors recovered twice as fast as bipolar cells.Conclusions. Vitrectomy causes significant inhibition of photoreceptors, bipolar and ganglion cells electrogenesis. The duration of vitrectomy is a significant negative factor determining retinal and optic nerve electrogenesis inhibition in the postop. Intraocular C3F8 gas, silicon oil tamponade (compared to air tamponade) is a significant adverse factor affecting retinal and optic nerve electrogenesis inhibition in the postop. The primary full-thickness macular hole diameter is a significant factor in inhibiting electrogenesis of the retinal cone system. Photoreceptors have a greater rehabilitation ability than bipolar cells.

For prevention of ophthalmic herpes recurrence and optimal results of anti-relapse therapy of patients with recurrent ophthalmic herpes were shown concurrently with the beginning of the standard antiherpetic treatment courses of plasmapheresis with ozone therapy and spend it as monotherapy at the end of treatment.
Kesesuaian hasil ultrasonografi dan diagnosis klinis terhadap pemeriksaan histopatologis penderita limfadenitis tuberkulosis regio servikal
Authors: Aditya Mikhael , Simargi Yopi
Published: March 2019

LATAR BELAKANGLimfadenopati regio servikal merupakan kasus yang sering terjadi sebagai manifestasi berbagai penyakit, termasuk tuberkulosis. Teknik pemeriksaan kelenjar getah bening yang menjadi standar baku adalah histopatologi. Pemeriksaan non-invasif berupa ultrasonografi (USG) dapat menjadi alternatif untuk menegakkan diagnosis tuberkulosis kelenjar getah bening. Oleh karena itu, penelitian dilakukan untuk mengetahui nilai kesesuaian USG sebagai alat diagnosis limfadenitis tuberkulosis, termasuk nilai akurasi, sensitivitas, spesifisitas, nilai duga positif, dan nilai duga negatif dibandingkan dengan standar baku.

METODEPenelitian dilakukan secara deskriptif retrospektif dengan teknik pengambilan sampel potong lintang (cross-sectional) menggunakan 100 rekam medis pasien limfadenopati regio servikal di rumah sakit (RS) Atma Jaya, Jakarta. Waktu pemeriksaan ultrasonografi dan histopatologi pada periode Oktober 2015 hingga Oktober 2017. Analisis data dilakukan untuk mengetahui akurasi, sensitivitas, spesifisitas, nilai duga positif, dan nilai duga negatif, serta tingkat kemaknaan hasil ultrasonografi dan diagnosis klinis dalam mendiagnosis tuberkulosis. Analisis data menggunakan uji proporsi sampel dengan tingkat kemaknaan p<0.05.

HASILSebanyak 59 pasien (59.0%) terdiagnosis tuberkulosis berdasarkan pemeriksaan histopatologi. Akurasi, sensitivitas, spesifisitas, nilai duga positif, dan nilai duga negatif ultrasonografi berturut-turut sebesar 69.0%; 59.3%; 83.0%; 83.3%; dan 58.6%. Pengujian data menunjukkan perbedaan bermakna hasil ultrasonografi terhadap hasil histopatologi (p=0.0005), sehingga hasil ultrasonografi dianggap belum sesuai secara statistik.

KESIMPULANUltrasonografi belum dapat menjadi alternatif pilihan untuk menegakkan diagnosis tuberkulosis secara statistik, namun dapat menjadi alat evaluasi tuberkulosis yang baik. Penelitian lebih lanjut masih perlu dilakukan.

Background: Rural Bengal has one of the highest snakebite prevalence in India. This prospective observational study was initiated with the motive to analyse the effects and adherence to implementation of the new national snakebite protocol 2016.Methods: Data were collected from the patients admitted with snake bite on a pre-designed and pre tested case study form and analysed with the help of descriptive statistics.Results: A total of 75 patients arrived in the hospital during the study period out which 53 were male (most in the age group of 31-40 years) and majority of them were farmers (26.6%) or housewives (25%). Maximum of them were bitten in the lower limbs (54.6%) and peak time of bite was between 6 am-12 pm (40%). Most of them reached the hospital late, i.e., beyond 2 hours (70.6%). It was found that there were 26 neurotoxic, 16 hemotoxic and 1 neuro-hemotoxic cases and the rest were non-venomous cases. Fifty-one of them received ASV and 4 died. There was 80% adherence in the indication of ASV administration, 73.3% in the ASV dose, 32% in the monitoring after ASV administration, 94.66% in the monitoring 20 WBCT, 100% in adherence to haemodialysis as indicated.Conclusions: The results showed good adherence in all the parameters. Protocol guided treatment has also resulted in rational use of ASV. So, from this study, it was concluded that protocol guided treatment is effective in snakebite management, but its continuous revision and amendments should be considered in future.

Authors: Pooswamy Shanmuga Sundaram , Muralidharagopalan Niranjanan Raghavn
Published: March 2019

Background: De Quervain’s disease or stenosing tenosynovitis of the first dorsal compartment of the wrist is a common condition, which affects the Abductor pollicis longus and the extensor pollicis brevis tendons. There are characteristic signs and symptoms including a positive Finkelstein's test. Different options for treatment include conservative approaches like analgesics, splinting and physical therapy. If conservative options fail then steroid injection is considered.

Methods: This is a retrospective study of single dose intra-sheath triamcinolone and lignocaine injection in 32 patients at our institute who were followed up for a period of 12 months.

Results: In our study there were 25 females and 7 males with a mean age of 46.4±8.03 years. Right side was involved in 17 patients and left side in 15 patients. The pre procedure VAS score was 8.65±1.07. The follow up VAS scores at 1, 6 and 12 months respectively were 1.4±1.14, 0.84±1.06 and 1.03±1.26 respectively. 4 out of 32 patients had positive Finkelstein’s test at 1 year follow up. Common complications were pain at injection site, which was seen in 5/32 patients and depigmentation seen in 2/32 patients.

Conclusions: Thus intra sheath triamcinolone injection is a safe and effective procedure for treatment of De Quervains disease.
CPN Tools-Assisted Simulation and Verification of Nested Petri Nets
Authors: Dworza´nski L. W. , Lomazova I. A.
Published: March 2019

Nested Petri nets (NP-nets) are an extension of Petri net formalism within the “netswithin-nets” approach, when tokens in a marking are Petri nets, which have an autonomous behavior and are synchronized with the system net. The formalism of NP-nets allows modeling multi-level multi-agent systems with dynamic structure in a natural way. Currently, there is no tool for supporting NP-nets simulation and analysis. The paper proposes the translation of NP-nets into Colored Petri nets and the use of CPN Tools as a virtual machine for NP-nets modeling, simulation and automatic verification.

About Some Localization Problems in Delaunay Triangulations
Authors: Dyshkant N. F.
Published: March 2019

We study some problems of nodes localization in a Delaunay triangulation and problem-solving procedures. For the problem of the set of nodes the computationally efficient approach that uses Euclidean minimum spanning tree of Delaunay triangulation is proposed. Efficient estimations for computational comlexity of the proposed methods in the average and in the worst cases are proved.

On the Residual Finiteness of Some Generalized Products of Soluble Groups of Finite Rank
Authors: Rozov A. V.
Published: March 2019

Let G be a free product of residually finite virtually soluble groups A and B of finite rank with an amalgamated subgroup H, H 6= A and H 6= B. And let H contains a subgroup W of finite index which is normal in both A and B. We prove that the group G is residually finite if and only if the subgroup H is finitely separable in A and B. Also we prove that if all subgroups of A and B are finitely separable in A and B, respectively, all finitely generated subgroups of G are finitely separable in G.
Isoperimetric and Functional Inequalities
Authors: Klimov Vladimir S.
Published: March 2019

We establish lower estimates for an integral functional$$\int\limits_\Omega f(u(x), \nabla u(x)) \, dx ,$$where \(\Omega\) -- a bounded domain in \(\mathbb{R}^n \; (n \geqslant 2)\), an integrand \(f(t,p) \, (t \in [0, \infty),\; p \in \mathbb{R}^n)\) -- a function that is \(B\)-measurable with respect to a variable \(t\) and is convex and even in the variable \(p\), \(\nabla u(x)\) -- a gradient (in the sense of Sobolev) of the function \(u \colon \Omega \rightarrow \mathbb{R}\). In the first and the second sections we utilize properties of permutations of differentiable functions and an isoperimetric inequality \(H^{n-1}( \partial A) \geqslant \lambda(m_n A)\), that connects \((n-1)\)-dimensional Hausdorff measure \(H^{n-1}(\partial A )\) of relative boundary \(\partial A\) of the set \(A \subset \Omega\) with its \(n\)-dimensional Lebesgue measure \(m_n A\). The integrand \(f\) is assumed to be isotropic, i.e. \(f(t,p) = f(t,q)\) if \(|p| = |q|\).Applications of the established results to multidimensional variational problems are outlined. For functions \( u \) that vanish on the boundary of the domain \(\Omega\), the assumption of the isotropy of the integrand \( f \) can be omitted. In this case, an important role is played by the Steiner and Schwartz symmetrization operations of the integrand \( f \) and of the function \( u \). The corresponding variants of the lower estimates are discussed in the third section. What is fundamentally new here is that the symmetrization operation is applied not only to the function \(u\), but also to the integrand \(f\). The geometric basis of the results of the third section is the Brunn-Minkowski inequality, as well as the symmetrization properties of the algebraic sum of sets.

Published: March 2019

O presente estudo objetivou dimensionar um reservatório de regularização de vazão para atender as demandas no município de Itabuna – Bahia a partir de imagens de satélites. Para tal, foi estimada a população no ano de 2037 e sua demanda hídrica. A classificação supervisionada da carta do Landsat 8 de 2017 foi produzida para avaliação da área de estudo. O dimensionamento do reservatório foi realizado a partir da análise das curvas de nível. O mapa gerado a partir dessa análise foi sobreposto ao mapa de uso do solo para identificação e quantificação das classes alagadas. A população estimada para o ano de 2037 foi de 246.755 habitantes, para atender essa população o reservatório deve armazenar um volume de 53,29 hm³ e altura de 14 metros, mantendo uma vazão de 1,33 m³/s. A área alagada do reservatório foi de 1548 ha sendo que 1449 ha são áreas de pastagem e 99 ha de fragmentos florestais. O dimensionamento proposto, além de atender a demanda da população estimada, apresenta uma área de alagamento que 96,8% da cobertura vegetal, composta por pastagem, desta forma o trecho é o mais recomendado para construção do reservatório.

Published: March 2019

Backgrounds: Malaria is a major public health problem in the tropical and subtropical areas of the world, including Africa. Most cases of malaria in Africa are caused by Plasmodium falciparum. Objectives: This study was aimed to assess the hematological changes in patient with falciparum malaria and to estimate the incidence of leucopenia, thrombocytopenia, and its response to anti-malaria therapy, and to correlate the association of the hematological changes with P. falciparum-positive (study group) and P. falciparumnegative (control group).
Methodology: A total of 453 participants (353 cases and 100 as control group) were enrolled in this study, all of them were randomly selected from Elnihoud Teaching Hospital, Elnihoud Locality, West Kordufan State, Sudan. Questionnaire was filled by every participant and thick and thin blood films for malaria were prepared and stained by giemsa stain and the CBC was done by sysmex automated hematological analyzer.
Results: Thrombocytopenia, leucopenia, microcytic hypochromic red blood cells and relative lymphocytosis have significant association with falciparum malaria with Pvalues 0.008, 0.001, 0.008, and 0.004, respectively.
Conclusion: Patients with thrombocytopenia and/or leucopenia with malaria should receive anti-malaria therapy and follow-up by CBC, and shouldn’t be hurried for a bone marrow examination.
