RESUMO
INTRODUCTION: Timely diagnosis and proper recognition of Systemic Lupus Erythematosus (SLE) is essential to establish early management in inpatients and outpatients. There are different classification scales to identify SLE, which include various clinical and serological aspects. In 2021, the SLE Risk Probability Index (SLERPI) was published, which focuses predominantly on the clinical characteristics of patients with suspected SLE and uses a simple algorithm for early recognition of the disease. The aim of this study is to compare the European League Against Rheumatism/American College of Rheumatology (ACR/EULAR) classification criteria, the Systemic Lupus International Collaborating Clinics (SLICC) criteria, and the SLERPI criteria in a cohort of Colombian patients with SLE and to analyze the correlations observed between their absolute scores. METHODS: A registry of SLE patients from two referral hospitals in Bogotá, Colombia, was used. 2021 SLERPI, 2019 ACR/EULAR, and 2012 SLICC scores were calculated for each patient and the correlations found between the scales were analyzed. The sensitivities of each were compared, and frequency analyses were conducted among different clinical and laboratory variables. RESULTS: Between 2016 and 2019, 146 patients diagnosed with SLE were registered, including inpatients and outpatients. The median age was 36 years (interquartile range 26-51), and 82.2% were women. According to the SLERPI criteria, a high prevalence of antinuclear antibodies (92%), immunological disorders (71%), and arthritis (64%) were observed. The most used treatments were corticosteroids (87.6%) and chloroquine (67.8%). A Spearman evaluation analysis was performed, with a moderately strong correlation of 0.76 (p = .000) between the SLERPI and ACR/EULAR scales and very strong correlation of 0.80 (p = .000) between the SLERPI and SLICC. Patients classified with SLE according to the SLERPI scale exhibited a higher incidence of hematological compromise, along with elevated levels of serological markers such as anti-DNA antibodies. Additionally, this group more commonly received treatments involving corticosteroids and azathioprine, and displayed a higher prevalence of hypertension. CONCLUSION: The SLERPI scale could be useful in the diagnosis of SLE, especially in early stages, given its good correlation with other classification scales and its good sensitivity.

DNA damage, arising from endogenous metabolism or exposure to environmental agents, may perturb the transmission of genetic information by blocking DNA replication and/or inducing mutations, which contribute to the development of cancer and likely other human diseases. Hydroxyl radical attack on the C1', C3' and C4' of 2-deoxyribose can give rise to epimeric 2-deoxyribose lesions, for which the in vivo occurrence and biological consequences remain largely unexplored. Through independent chemical syntheses of all three epimeric lesions of 2'-deoxyguanosine (dG) and liquid chromatography-tandem mass spectrometry analysis, we demonstrated unambiguously the presence of substantial levels of the α-anomer of dG (α-dG) in calf thymus DNA and in DNA isolated from mouse pancreatic tissues. We further assessed quantitatively the impact of all four α-dN lesions on DNA replication in Escherichia coli by employing a shuttle-vector method. We found that, without SOS induction, all α-dN lesions except α-dA strongly blocked DNA replication and, while replication across α-dA was error-free, replicative bypass of α-dC and α-dG yielded mainly CâA and GâA mutations. In addition, SOS induction could lead to markedly elevated bypass efficiencies for the four α-dN lesions, abolished the GâA mutation for α-dG, pronouncedly reduced the CâA mutation for α-dC and triggered TâA mutation for α-dT. The preferential misincorporation of dTMP opposite the α-dNs could be attributed to the unique base-pairing properties of the nucleobases elicited by the inversion of the configuration of the N-glycosidic linkage. Our results also revealed that Pol V played a major role in bypassing α-dC, α-dG and α-dT in vivo. The abundance of α-dG in mammalian tissue and the impact of the α-dNs on DNA replication demonstrate for the first time the biological significance of this family of DNA lesions.

The purpose of this study was to develop a simple and sensitive CE-UV method to quantify erlotinib and metabolites in urine. Following liquid-liquid extraction, erlotinib, and metabolites were separated with a BGE whose composition was phosphate buffer (pH 2.5, 65 mM) with 0.5% Tween 20. The applied voltage was 22 kV, capillary temperature 25°C and the sample injection was performed in the hydrodynamic mode. All the analyses were carried out in a fused silica capillary with an internal diameter of 75 µm and a total length of 37 cm. The detection of target compounds was performed at 240 nm. The calibration was linear in the range 0.15-20 mg/L for erlotinib and metabolites. Inter-and intraday imprecision were less than 4%. This simple, sensitive, accurate, and cost-effective method can be used in routine clinical practice to monitor erlotinib concentrations in urine from nonsmall cell lung cancer patients.

PURPOSE: The aim of this study was to assess the construct validity and clinical application of the Pediatric Sleep Survey Instrument (PSSI) as a tool to screen for sleep disordered breathing (SDB) in children. METHODS: Polysomnography (PSG) outcomes and PSSI subscale scores were compared between a clinical cohort (N = 87, 5-10 years, 62 M/25 F) and a nonsnoring community sample (N = 55, 5-10 years, 28 M/27 F). Group comparisons assessed the ability of the PSSI subscales to discriminate between the clinical and community cohorts. Receiver operating characteristic (ROC) curves assessed construct validity, with the Apnea/Hypopnea Index (AHI) >5 events/h, OSA-18 score >60, and Pediatric Daytime Sleepiness Scale (PDSS) above the 70th percentile as the target references. RESULTS: The clinical group had more respiratory events, respiratory-related arousals, fragmented sleep, and lower oxygen saturation nadir than the community group (p < 0.001 for all). PSSI subscale scores of Morning Tiredness, Night Arousals, SDB, and Restless Sleep were higher (p < 0.001 for all) in the clinical cohort, confirming the tool's ability to identify clinically relevant sleep problems. ROC curves confirmed the diagnostic accuracy of the SDB subscale against an AHI > 5 events/h (area under the curve (AUC) = 0.7), an OSA-18 score >60 (AUC = 0.7), and a PDSS score in the 70th percentile (AUC = 0.8). The Morning Tiredness subscale accurately predicted a PDSS score in the 70th percentile (AUC = 0.8). A cutoff score of 5 on the SDB subscale showed a sensitivity of 0.94 and a specificity of 0.76, correctly identifying 77 and 100 % of the clinical and community cohorts, respectively. CONCLUSION: The PSSI Sleep Disordered Breathing subscale is a valid tool for screening SDB and daytime sleepiness in children aged 5-10 years.

INTRODUCTION AND OBJECTIVE: Intravenous immunoglobulin (IVIg) is an anti-inflammatory drug with an unclear role in the treatment of patients with lupus nephritis (LN). This systematic review evaluates the evidence for IVIg in the care of patients with LN. METHODOLOGY: A systematic search was done in the PubMed, EMBASE, BVS and OVID databases - All EBM Reviews following the PRISMA methodology (registration in PROSPERO CRD42021236662). The variables were extracted: indications for use, dosage, partial or complete response, adverse reactions, initiation of renal replacement therapy, reduction of proteinuria, and mortality. The quality assessment was done with the "The Joanna Briggs Institute (JBI) Critical Appraisal tools for use in Systematic Reviews Checklist". In addition, synthesis reports were prepared through the Synthesis Without Meta-analysis - SWiM guide. RESULTS: A total of 2328 articles were obtained (28 were considered for inclusion). When the studies were evaluated, IVIg therapy was found to be between 60% to 70% effective (except for patients with class V LN) with overall responses (complete + partial) even for patients who are refractory to first line treatment. Normalization (<0.5 g) of nephrotic proteinuria occurred in 24% of cases with infrequent adverse events and a mortality plus dialysis composite of 11.5% and 24.1% (most representative study). CONCLUSION: In patients with LN refractory to conventional treatment or co-infection situations, the reported data seem to demonstrate effectiveness of IVIg therapy. There are few adverse reactions and caution is exercised when using it on patients with class V NL. However, given the lack of controlled studies with long-term follow-up, these data should be interpreted cautiously thus encouraging the development of high-quality RCTs.

As gestational surrogacy was forbidden in France in July 2015, the French supreme court decided to depart from previous case-law on the matter after the European Court of Human Rights (ECHR) ruled against France in four separate cases. Now, (as in the April 2017 communication1), the French Cour de Cassation has ruled that in the case of gestational surrogacy carried out abroad, the birth certificate of a child born by way of such method may be added to the French civil register along with the father’s name and without the mother’s name as she did not deliver birth.The article provides an analysis of this change in case-law. First part will examine the evolution of gestational surrogacy-related case-law and the measures taken by the French legislator on the matter. Second part will focus on the Cour de cassation’s turnaround in case-law that followed the ECHR ruling against France on the issue of the approval by domestic law of the legal relationship established between a French biological father and a child born abroad as a result of surrogacy treatment.

INTRODUCTION: Axillary lymph node involvement is recognized as a key prognostic factor for invasive breast cancer. Retrospective analyzes have shown that extracapsular extension (ECE) is correlated with negative prognostic factors in this neoplasia. OBJECTIVE: to evaluate the measurement of ECE and its relationship with the number of affected non-sentinel lymph nodes, as well as to investigate the association between ECE with other clinical and pathological prognostic factors. METHODS: This is a cross-sectional observational study carried out from January 2015 to June 2019, at the Breast Surgical Oncology service of Liga Contra o Cancer (LIGA), in Natal, Brazil. A total of 150 patients were included in the study and were divided into three groups: absence of ECE, ECE less than or equal to 2 mm and ECE greater than 2 mm. RESULTS: The mean age was 58 years for the group with ECE and 57 years for the group without ECE. Most of the patients were mixed race (66.7%), had no family history of breast cancer (64%) and underwent quadrantectomy (64.5%). Regarding the characteristics of the disease, most presented a histological report compatible with Invasive Carcinoma of the non-special type (IC NST) (87.5%), histological grade II (52.7%), negative Lymphovascular invasion (LVI) (52.7%), Tumor Size T1 (<2.0 cm) (52%) and Luminal B molecular subtype (36.7%). Regarding sentinel lymph nodes: 103 patients (68.7%) had ECE and 1 positive sentinel lymph node was identified in most cases. There was a statistically significant association between the presence of ECE and of being mixed race (p = 0.03), between ECE and LVI (p = 0.05) and between ECE and a greater number of positive non-sentinel lymph nodes (p < 0.001). CONCLUSION: Our study showed that ECE> 2 mm is associated with increased axillary nodal load compared to groups without ECE and ECE ≤ 2 mm in sentinel node biopsy in patients who met the Z0011 criteria.

BACKGROUND: /Objective: Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease with a wide range of clinical manifestations. The latest classification criteria, EULAR/ACR 2019, have not been validated in a Latin American population of Amerindian ancestry. The objective of this study is to compare the sensitivity of the EULAR/ACR 2019 and SLICC 2012 classification criteria in a group of SLE patients with the above ancestry. METHODS: A cross-sectional study was done. Data were obtained from the review of medical records of patients who met the inclusion criteria. The overall sensitivity of the criteria was calculated and compared to each other using the McNemar test. RESULTS: 146 medical records of patients from two referral centers were included. There were no differences in the sensitivity of the EULAR/ACR and SLICC 2012 criteria (84.9% versus 85.6% p = 0.79) nor were differences found when the groups based on disease duration were compared: less than 5 years (91.0% versus 92.5% p = 0.70), between 5 and 10 years (82.8% versus 82.8% p = 1), and 10 years or more (76.7% versus 76.7% p = 1). However, SLICC 2012 criteria was found to better classify patients with a less than 5-year disease duration compared to those with 10-year duration or more (92.5% versus 76.4% p = 0.024). CONCLUSIONS: There are no statistically significant differences between the EULAR/ACR and SLICC 2012 criteria in the population studied. Nor were differences found when evaluating them by age at diagnosis and duration of the disease except when the group with less than 5 years of duration was compared to those with 10 years or more using the SLICC 2012 criteria.
RESUMO
BACKGROUND: It is not clear whether patients with some degree of immunosuppression have worse outcomes in SARS-CoV-2 infection, compared to healthy people. OBJECTIVE: To carry out a narrative review of the information available on infection by SARS-CoV-2 in immunosuppressed patients, especially patients with cancer, transplanted, neurological diseases, primary and secondary immunodeficiencies. RESULTS: Patients with cancer and recent cancer treatment (chemotherapy or surgery) and SARS-CoV-2 infection have a higher risk of worse outcomes. In transplant patients (renal, cardiac and hepatic), with neurological pathologies (multiple sclerosis (MS), neuromyelitis optica (NMODS), myasthenia gravis (MG)), primary immunodeficiencies and infection with human immunodeficiency virus (HIV) in association with immunosuppressants, studies have shown no tendency for worse outcomes. CONCLUSION: Given the little evidence we have so far, the behaviour of SARS-CoV-2 infection in immunosuppressed patients is unclear, but current studies have not shown worse outcomes, except for patients with cancer.

CONCLUSION: Given the little evidence we have so far, the behaviour of SARS-CoV-2 infection in immunosuppressed patients is unclear, but current studies have not shown worse outcomes, except for patients with cancer.
RESUMO
Introduction: Cardiac function is modulated by multiple factors including exogenous (circadian rhythm) and endogenous (ultradian 90-110 min sleep cycle) factors. By evaluating heart rate variability (HRV) during sleep, we will better understand their influence on cardiac activity. The aim of this study was to evaluate HRV in the dark phase of the circadian rhythm during sleep in healthy children and adolescents. Methods: One 3 min segment of pre-sleep electrocardiography (EEG) and 3, 6 min segments of electrocardiography recorded during polysomnography from 75 healthy children and adolescents were sampled during progressive cycles of slow wave sleep (SWS1, SWS2, SWS3). Three, 3 min segments of rapid eye movement sleep (REM) were also assessed, with REM1 marked at the last REM period before awakening. Studies that recorded REM3 prior to SWS3 were used for assessment. HRV variables include the following time domain values: mean NN (average RR intervals over given time), SDNN (Standard Deviation of RR intervals), and RMSSD (root Mean Square of beat-to-beat Differences). Frequency domain values include: low frequency (LF), high frequency (HF), and LF:HF. Results: Mixed linear effects model analysis revealed a significant difference in time and frequency domain values between sleep cycles and stages. Mean NN was lowest (highest heart rate) during pre-sleep then significantly increased across SWS1-3. Mean NN in SWS1 was similar to all REM periods which was significantly lower than both SWS2 and SWS3. SDNN remained at pre-sleep levels until SWS3, and then significantly increased in REM1&2. There was a large drop in LF from pre-sleep to SWS1. As cycles progressed through the night, LF remains lower than awake but increases to awake like levels by REM2. RMSSD and HF were lowest in pre-sleep and increased significantly by SWS1 and remain high and stable across stages and cycles except during the REM3 period where RMSSD decreased. Conclusion: Our results demonstrate that there are considerable changes in the spectral analysis of cardiac function occurring during different sleep stages and between sleep cycles across the night. Hence, time of night and sleep stage need to be considered when reporting any HRV differences.
RESUMO
Introduction: Axillary dissection is increasingly less indicated for axillary evaluation of patients with breast cancer and clinically negative axilla. This study evaluated the application of sentinel lymph node in patients with clinical axillary remission after neoadjuvant chemotherapy. Methods: Prospective study carried out from December 2017 to July 2018, at the Liga Norte Riograndense Contra o Cancer. We considered 24 patients who had a positive axilla and after neoadjuvant chemotherapy had clinical axillary remission (ypN0). Only patients with a strongly positive status during physical examination were included, and biopsy and ultrasound examinations were not required to confirm axillary disease. The dual-tracer technique of sentinel lymph node biopsy followed by axillary dissection was used. Results: The accuracy of the sentinel lymph node in patients with clinical axillary remission was 91.7%, with a false negative rate of 13.3% (2/24). It was observed that 66.6% of patients were stage I after chemotherapy and 13 patients with negative sentinel lymph node biopsy no longer had axillary disease. During the sentinel lymph node biopsy procedure, 16 patients (79.1%) had only 1 sentinel lymph node removed. Conclusions: For patients with clinical axillary remission after neoadjuvant chemotherapy, sentinel lymph node biopsy has been included in clinical practice, reducing the indications for axillary dissection and, consequently, its morbidity. The dual-agent mapping technique of sentinel lymph node biopsy and a sample of 3 lymph nodes at surgery decrease false-negative rates and make the procedure safer.
RESUMO
The first five years were recognized as a critical period of child growth. Accordingly, California voters approved tobacco tax through Proposition 10 to fund early childhood services since 1998. Due to the state revenue decline, Service Integration has been advocated to enhance program supports in Child Health, Family Functioning, and Child Development. In this study, interview data are analyzed to examine the partnership building among 40 programs. The results indicate a significant impact of the service outreach across remote communities in Kern County, California. In addition, contextual information is provided to facilitate interpretation of the partnership strength from a social network analysis. Enhancement of this investigation is discussed in light of future development.

The healthspan of mice is enhanced by killing senescent cells using a transgenic suicide gene. Achieving the same using small molecules would have a tremendous impact on quality of life and the burden of age-related chronic diseases. Here, we describe the rationale for identification and validation of a new class of drugs termed senolytics, which selectively kill senescent cells. By transcript analysis, we discovered increased expression of pro-survival networks in senescent cells, consistent with their established resistance to apoptosis. Using siRNA to silence expression of key nodes of this network, including ephrins (EFNB1 or 3), PI3Kδ, p21, BCL-xL, or plasminogen-activated inhibitor-2, killed senescent cells, but not proliferating or quiescent, differentiated cells. Drugs targeting these same factors selectively killed senescent cells. Dasatinib eliminated senescent human fat cell progenitors, while quercetin was more effective against senescent human endothelial cells and mouse BM-MSCs. The combination of dasatinib and quercetin was effective in eliminating senescent MEFs. In vivo, this combination reduced senescent cell burden in chronologically aged, radiation-exposed, and progeroid Ercc1(-/Δ) mice. In old mice, cardiac function and carotid vascular reactivity were improved 5 days after a single dose. Following irradiation of one limb in mice, a single dose led to improved exercise capacity for at least 7 months following drug treatment. Periodic drug administration extended healthspan in Ercc1(-/∆) mice, delaying age-related symptoms and pathology, osteoporosis, and loss of intervertebral disk proteoglycans. These results demonstrate the feasibility of selectively ablating senescent cells and the efficacy of senolytics for alleviating symptoms of frailty and extending healthspan.

Introduction: The proper selection of patients for sentinel lymph node biopsy is essential and depends on the evaluation of the patient's prediction for lymph node involvement and an evaluation of the accuracy of the clinical examination. Objective: This study aimed to evaluate the axillary contents of 102 breast cancer patients with tumors between 3 and 5 centimeters who underwent axillary dissection between January 2010 and December 2013. Methods: The data were categorized according to positive or negative axillary clinical evaluation and positive or negative anatomopathological evaluation. Results: The value for positive predictive values for physical examination was 83.5% and the negative predictive value was 34.88%. In addition, axillary physical examination showed 63.6% sensitivity and 60% specificity. Most patients with axillary involvement in the anatomopathological evaluation correlated with tumor grade, size, location and angiolymphatic invasion. Conclusion: It is believed that a better evaluation of the prediction of lymph node involvement, considering some clinicopathological risk factors in patients with suspicious lymph nodes, should be performed to aid the preoperative study of the axilla and the axillary approach screening
Introdução: Atualmente, precisamos selecionar adequadamente as pacientes a serem submetidas à biópsia de linfonodo sentinela. Para isso, são imprescindíveis a avaliação da predição daquele paciente acerca do comprometimento linfonodal e a avaliação da acurácia do exame clínico. Objetivo: O presente estudo teve como objetivo avaliar o conteúdo axilar de pacientes portadoras de câncer de mama com tumores entre três e cinco centímetros submetidas ao esvaziamento axilar entre 2010 e 2013, por meio da análise de 102 prontuários. Métodos: Os dados foram categorizados segundo a avaliação clínica axilar positiva ou negativa e a avaliação anatomopatológica positiva ou negativa. Resultados: Observaram-se valor preditivo positivo do exame físico de 83,5% e preditivo negativo de 34,88%. O exame físico axilar mostrou sensibilidade de 63,6% e especificidade de 60%. A maioria das pacientes com comprometimento axilar no anatomopatológico mostrou correlação com o grau tumoral, tamanho, localização e invasão angiolinfática. Conclusão: Acredita-se que uma melhor avaliação quanto à predição do comprometimento linfonodal, levando em consideração alguns fatores clinicopatológicos de risco nas pacientes com linfonodos suspeitos, deve ser feita como auxílio no estudo pré-operatório da axila e triagem no tocante à abordagem axilar
RESUMO
Two nectarine cultivars ('Flavela' and 'Flanoba') were treated with Aloe vera gel alone, or with the addition of thymol, and then inoculated with Rhizopus stolonifer, Botrytis cinerea and Penicillium digitatum. Both treatments were effective in reducing the decay incidence caused by the 3 fungi species, although the addition of thymol did not generally improve the efficacy of Aloe vera gel on reducing the infection damage. The coatings were clearly effective in reducing the postharvest ripening process of both nectarine cultivars manifested by a delay in ethylene production and respiration rate, weight loss and softening. Interestingly, these coatings showed effectiveness on reducing decay development in inoculated fruits and thus Aloe vera could be considered as natural antifungal compound and might serve as alternative of synthetic fungicides.

Las membranas neovasculares peripapilares son una complicación rara del papiledema crónico, y son aún más infrecuentes en el contexto del papiledema por hipertensión endocraneana idiopática (HEI). Dada su escasez, es difícil plantear estudios para definir la alternativa terapéutica más adecuada. Se presenta el caso de una mujer con papiledema por HEI quien desarrolló membrana neovascular peripapilar, y cuyo tratamiento con ranibizumab intravítreo fue exitoso.
Peripapillary neovascular membrane is a rare complication of chronic papiledema. When the latter is due to idiopathic intracranial hypertension, neovascularization is even rarer. Because of this low occurrence, it is difficult to design studies to define the most appropriate treatment. We report the case of a woman who developed papiledema by idiopathic intracranial hypertension with peripapillary neovascular membrane, and who was successfully treated with intravitreal ranibizumab.

Objetivo: el objetivo principal de esta revisión sistemática es evaluar eficacia y seguridad de los antibióticos sistémicos en la retinocoroiditis activa por toxoplasmosis. Metodología: se realizó una búsqueda en la que se incluyeron ensayos clínicos controlados aleatorizados o cuasi aleatorizados. Se excluyeron estudios en pacientes inmunocomprometidos. Se incluyeron estudios de pacientes tratados para retinocoroiditis aguda o con cicatrices retinocoroideas inactivas y con historia de dos o más episodios recurrentes de enfermedad activa. Se incluyeron regímenes de antibióticos conocidos (trimetoprim/sulfametoxazol, pirimetamina/sulfadiazina, pirimetamina/ azitromicina) y ampliamente utilizados contra el Toxoplasma gondii. Resultados: los resultados primarios para esta revisión fueron agudeza visual y aparición de recurrencias, definidas como un nuevo foco de inflamación retinocoroidea adyacente a una cicatriz previa. Los resultados secundarios fueron efectos adversos, reducción del tamaño de la lesión retinocoroidea y duración, severidad y frecuencia de los signos y síntomas por la inflamación intraocular. Conclusiones: todavía existe una falta de evidencia que soporte el antibiótico y dosis óptima ideal para el manejo de retinocoroiditis por toxoplasmosis, así como tratamiento profiláctico ideal para las recurrencias.
Objective: The main objective of this systematic review is to evaluate safety and efficacy of systemic antibiotics in active toxoplasmic retinochoroiditis.Methods: An important search was conducted which included randomized or quasi-randomized controlled clinical trials. Studies carried out in immunocompromised patients were excluded. Studies of patients treated for acute retinochoroiditis or patients with inactive retinochoroidal scars and a history of two or more recurrent episodes of active disease were included. Well-known antibiotic regimens (trimethoprim/sulfamethoxazole, pyrimethamine/sulfadiazine, pyrimethamine/azithromycin), which have been widely used against Toxoplasma gondii, were included.Results: The primary outcomes for this review were visual acuity and recurrences, defined as a new focus of inflammation next to a preexisting scar. Secondary outcomes were adverse effects, reduction of retinochoroidal lesion size and duration, severity and frequency of signs and symptoms due to intraocular inflammation.Conclusions: There is still a lack of evidence to support the antibiotic and optimal dosage for the treatment of toxoplasmic retinochoroiditis, as well as the best prophylactic treatment for recurrences.
Objetivo: o objetivo principal desta revisão sistemática é avaliar eficácia e segurança dos antibióticos sistémicos na retinocoroidite ativa por toxoplasmoses.Metodologia: realizou-se uma busca importante em onde se incluíram ensaios clínicos controlados aleatorizados ou quase aleatorizados. Excluíram-se estudos em pacientes imuno-comprometidos. Incluíram-se estudos de pacientes tratados para retinocoroidite aguda ou com cicatrizes retinocoroidites inativas e com história de duas ou mais episódios recorrentes de doença ativa. Incluíram-se regimes de antibióticos conhecidos (trimetoprim/sulfametoxazol, pirimetamina/sulfadiazina, pirimetamina/azitromicina) e amplamente utilizados contra o Toxoplasma gondii. Resultados: os resultados primários para esta revisão foram agudeza visual e aparição de recorrências, definidas como um novo foco de inflamação retinocoroidite adjacente a uma cicatriz prévia. Os resultados secundários foram efeitos adversos, redução do tamanho da lesão retinocoroidite e duração, severidade e frequência dos signos e sintomas devido à inflamação intraocular. Conclusões: ainda existe uma falta de evidência que suporte o antibiótico e dose ótima ideal para o manejo de retinocoroidites por toxoplasmoses, bem como tratamento profiláctico ideal para as recorrências.
