ABSTRACT
ABSTRACT Purpose: To evaluate contrast sensitivity in non-high-risk, treatment-naïve proliferative diabetic retinopathy patients treated with panretinal photocoagulation and intravitreal injections of ranibizumab) versus panretinal photocoagulation alone. Methods: Sixty eyes of 30 patients with bilateral proliferative diabetic retinopathy were randomized into two groups: one received panretinal photocoagulation and ranibizumab injections (study group), while the other received panretinal photocoagulation alone (control group). All eyes were treated with panretinal photocoagulation in three sessions according to the Early Treatment Diabetic Retinopathy Study guidelines. Contrast sensitivity measurements were performed under photopic conditions (85 cd/m2) with the Visual Contrast Test Sensitivity 6500 chart, allowing for the evaluation of five spatial frequencies with sine wave grating charts: 1.5, 3.0, 6.0, 12.0, and 18.0 cycles per degree (cpd). Outcomes were measured in contrast sensitivity threshold scores among and within groups, from baseline to 1, 3, and 6 months. Results: Fifty-eight eyes (28 in the study group and 30 in the control group) reached the study endpoint. A comparative analysis of changes in contrast sensitivity between the groups showed significant differences mainly in low frequencies as follows: at month 1 in 1.5 cpd (p=0.001) and 3.0 cpd (p=0.04); at month 3 in 1.5 cpd (p=0.016), and at month 6 in 1.5 cpd (p=0.001) and 3.0 cpd (p=0.026) in favor of the study group. Conclusions: In eyes of patients with non-high-risk proliferative diabetic retinopathy, panretinal photocoagulation treatment with ranibizumab appears to cause less damage to contrast sensitivity compared with panretinal photocoagulation treatment alone. Thus, our evaluation of contrast sensitivity may support the use of ranabizumab as an adjuvant to panretinal photocoagulation for the treatment of proliferative diabetic retinopathy.
RESUMO Objetivos: Avaliar a sensibilidade ao contraste em pacientes virgens de tratamento com retinopatia diabética proliferativa de não alto risco, submetidos a panfotocoagulação retiniana com injeções intravítreas de ranibizumabe versus panfotocoagulação isolada. Métodos: Sessenta olhos de 30 pacientes foram randomizados em dois grupos: um submetido a panfotocoagulação com injeções de ranibizumabe (grupo estudo), e o outro submetimedo a panfotocoagulação isolada (grupo controle). Todos olhos foram tratados em 3 sessões de laser, seguindo recomendação do Early Treatment Diabetic Retinopathy Study (ETDRS). Avaliação da sensibilidade ao contraste foi realizada sob condições fotópicas (85 cd/m2) com tabela Visual Contrast Test Sensitivity 6500, permitindo avaliação de cinco frequências espaciais medidas com redes senoidais: 1.5, 3.0, 6.0, 12.0 e 18.0 ciclos por grau de ângulo visual (cpd). Foram realizadas medidas dos limiares de sensibilidade ao contraste intra e entre grupos na visita inicial, no 1º, 3º, e 6º mês de seguimento. Resultados: Cinquenta e oito olhos, 28 do grupo estudo e 30 do grupo controle, atingiram o término do estudo. Análise comparativa da SC entre os grupos mostrou diferença estatisticamente significante, nas baixas frequências espaciais, no 1º mês em 1.5 cpd (p=0,001) e 3.0 cpd (p=0,04), no 3º mês em 1.5 cpd (p=0,016) e no 6º mês em 3.0 cpd (p=0,026) a favor do grupo estudo. Conclusão: O tratamento com panfotocoagulação associada a injeção de ranibizumabe parece causar menos danos a sensibilidade ao contraste quando comparada com panfotocoagulação isolada em olhos com retinopatia diabética proliferativa de não alto risco. Dessa forma, os resultados apresentados podem justificar a associação do ranibizumabe à panfotocoagulação nestes pacientes.
ABSTRACT
@#Temporal bone rhabdomyosarcoma is an aggressive entity that simulates chronic otitis ear infection. It is the most common soft tissue sarcoma amongst pediatric patients. Herein, we would like to report a case of temporal bone rhabdomyosarcoma involving a 2-year-old boy who presented with a one-month history of otorrhea with facial asymmetry. Early treatment led to remission of this severe neoplasm
ABSTRACT
@#Background: Most postpartum women are prescribed at least one medication; so the safety of the medication is a major concern. In 2017, 11% of 815 questions received by the Pharmacy Drug Information Services at seven clinics in Dungun is related to medication use in breastfeeding. Thus, this study was carried out to evaluate the attitudes of healthcare providers (HCPs) and to investigate the effect of knowledge about medication use in breastfeeding among HCPs; pre- and post-educational intervention.Methods: An interventional study was carried out among medical officers, assistant medical officers, pharmacists and pharmacist assistants from seven clinics in the district of Dungun, Malaysia. The questionnaires were distributed during pre- and post-intervention period. The interventions in this study included continuous medical education (CME) and the use of a booklet regarding medication use for breastfeeding women. The data collected were analyzed using Statistical Package for Social Studies (SPSS) and presented as frequencies, means, and standard deviations.Results: Fifty HCPs were enrolled in this study and over 20% of them advised mothers to discontinue breastfeeding whenever they are prescribed any medication. The knowledge of HCPs about medication use in breastfeeding women was significantly improved (Z= -5.917, p<0.001) following the educational intervention.Conclusion: CME and a simplified booklet appeared to have a positive impact on the knowledge of HCPs regarding medication use in breastfeeding
ABSTRACT
@#Dengue fever is a mosquito-borne disease that occurs in tropical and sub-tropical areas of the world. A severe form of dengue fever, also called dengue haemorrhagic fever, can cause severe bleeding, a sudden drop in blood pressure (shock) and death. The incidence of dengue fever has grown dramatically around the world in recent decades. The purpose of this study was to determine factors affecting prevention practices for dengue fever within the community. A cross-sectional study was conducted in the the municipality of Banda Aceh and district of Aceh Besar, Aceh Province, Indonesia. The sample size was 203, and the study instrument was a questionnaire. The study results showed that female respondents, 71 (75,5%) seem to have practiced prevention of dengue fever more as compared to the males (58,7%) or 64 respondents. Respondents in early adulthood (75 people or 54.7%) practiced more dengue prevention than older respondents. Meanwhile, respondents with higher levels of education, 85 (87.6%) practiced more dengue prevention than respondents with a middle level of education (47.2%) or 50 respondents. Respondents with good knowledge about dengue fever 128 (74%) practiced more prevention of dengue fever than respondent with a poor knowledge (23.3%) or 7 respondents. Respondents who had a positive attitude to the prevention of dengue fever, 108 (85.7%) practiced much more prevention than respondents who had a negative attitude (33.3%) or 25 respondents. Factors most affecting prevention practices for dengue fever were knowledge, attitude, education level, age and gender. Health promotion related to prevention of dengue fever should be done more in the media, especially using televison.

Objective: To investigate the acute toxicity of cadmium and lead on larvae of two tropical Chironomid species, Chironomus kiiensis (C. kiiensis) Tokunaga and Chironomus javanus (C. javanus) Kieffer. Methods: Different larval instars (first-fourth) were exposed using a static non-replacement testing procedures to various concentrations of cadmium and lead. Results:In general, younger larvae (first and second instars) of both species were more sensitive to both metals than older larvae (third and forth instars). The toxic effects of the metals on C. kiiensis and C. javanus were influenced by the age of the larvae (first to fourth instars), types of metals (cadmium or lead) and duration of larval exposure (24, 48, 72 and 96 h) to the metals. Conclusions: Cadmium was more toxic to the chironomids than lead and C. javanus was significantly more sensitive to both metals than C. kiiensis (P<0.05).
