Ocular syphilis is a re-emerging inflammatory eye disease with a clear gender imbalance, disproportionately affecting men. We investigated the impact of gender on the presentation, management practices and clinical outcomes of this condition. Data generated from a study of patients consecutively diagnosed with ocular syphilis who attended a subspecialist uveitis service at one of four hospitals in Brazil over a 30-month period were disaggregated for analysis by gender.

Purpose: To assess the quality of life in patients diagnosed as having tuberculous uveitis and its association with sociodemographic, clinical, and psychosocial aspects.

Method: By conducting standardized interviews, clinical and demographic data were collected using a measure developed in this study. This measure was applied in addition to other measures, namely SF-12, Hospital Anxiety and Depression Scale, and NEI-VFQ-39, which were used to assess health-related quality of life, anxiety and depression symptoms, and visual functioning.

Freshwater crustaceans of the genus Aegla are endemic to southern South America, and present greater richness in the river basins of the state of Rio Grande do Sul, Brazil. However, recent studies have shown the enormous potential for discovering new species of Aegla in the state of Paran. In the last six year the number of species recorded has almost doubled, increasing from 9 to 16.

Background: High rates of antibiotic use (AU) among inpatients with coronavirus disease 2019 (COVID-19) despite low rates of bacterial coinfection and secondary infection have been reported. We evaluated the impact of the COVID-19 pandemic on AU in healthcare facilities (HCFs) in South America.

Methods: We conducted an ecologic evaluation of AU in inpatient adult acute care wards in 2 HCFs each in Argentina, Brazil, and Chile.

Aim: To investigate the effect of gender on the clinical features and outcomes of ocular toxoplasmosis.

Methods: 262 patients (139 women and 123 men) presenting to a tertiary referral uveitis service in Ribeirão Preto, Brazil, with serological and clinical evidence of ocular toxoplasmosis were prospectively enrolled in an observational study. Predefined data items including demographics, descriptors of uveitis and ocular toxoplasmosis, best-corrected visual acuity and ocular complications were disaggregated by gender and compared statistically.

Article Synopsis
  • The incidence of multidrug resistant organisms (MDROs), particularly carbapenem-resistant Gram-negative bacteria and vancomycin-resistant Enterococcus, is significantly high among solid organ transplant (SOT) patients in Brazil.
  • This review highlights issues in antimicrobial use and resistance, focusing on the challenges and opportunities for establishing effective antimicrobial stewardship programs (ASPs) within Brazilian hospitals.
  • Key barriers to implementing ASPs include lack of specific national guidelines for SOT patients, inadequate electronic medical records, limited rapid diagnostic testing, and insufficient time for healthcare personnel to devote to stewardship activities.

Article Synopsis
  • * Although the intervention did not significantly reduce 30-day mortality rates, it resulted in shorter hospital and ICU stays, indicating potential efficiency gains in patient care.
  • * The use of RDTs led to decreased consumption of certain antibiotics, suggesting benefits for both clinical decisions and cost-effectiveness in managing antibiotic resistance.

Purpose: To analyse posterior segment optical coherence tomography (OCT) findings in ocular syphilis.

Methods: Medical records of 54 patients presenting consecutively with syphilitic uveitis were reviewed. Vitreous, retina and choroid (one eye/patient) were assessed by spectral-domain OCT on presentation (54 eyes) and after treatment (31 eyes).

Introduction: Vision impairment and blindness have been significantly associated with high medical care expenditures, decrease in health utility, and loss or reduction of productivity. The objective of this study was to assess the humanistic and economic burden of blindness in a Brazilian sample from a societal perspective.

Methods: Cross-sectional, observational, and multicenter study enrolling individuals with blindness (defined as the best corrected visual acuity less than 6/60 in the better-seeing eye) caused by retinal disorders.

Purpose: To evaluate vascular density in super-ficial and deep capillary plexuses of the retina, measured using optical coherence tomography angiography in patients with branch retinal vein occlusion. Affected eyes were compared with the contralateral eye of the same patient and both were compared with normal eyes.

Methods: A cross-sectional study including 16 previously untreated patients with branch retinal vein occlusion.

Purpose: To evaluate ophthalmic ultrasonographic findings associated with active ocular toxoplasmosis.

Methods: Forty-seven eyes with active ocular toxoplasmosis in 47 patients were subjected to ocular ultrasonography using the transpalpebral technique (10-MHz transducer) and fundus photography. Patient medical records were retrospectively reviewed.

Background: Syphilitic uveitis is re-emerging alongside the systemic infection. In July 2017, an international group of uveitis-specialised ophthalmologists formed the International Ocular Syphilis Study Group to define current practice patterns.

Methods: 103 Study Group members based in 35 countries completed a 25-item questionnaire focused on case load, clinical presentations, use and interpretation of investigations, treatment and clinical indicators of poor prognosis.

Recent reports from different world regions suggest ocular syphilis is re-emerging, in parallel with an increasing incidence of the systemic infection globally. We conducted a large observational study of 127 persons consecutively treated for ocular syphilis at public medical centers in Brazil over a 2.5-year period ending July 2015.

Purpose: To report unique retinal fundus lesions and treatment outcomes of intraocular tuberculosis in patients under anti-tumor necrosis factor treatment.

Methods: Retrospective review of two patients with laboratorial evidence of tuberculosis who had bilateral ocular signs and symptoms not attributable to other diseases. Multimodal imaging was analyzed at the time of presentation and after the treatment initiation.

Objective: To discuss the role of the clinical pharmacist in hospital care of critical elderly patients.

Methods: Critical patients aged 60 years and over admitted by the clinical staff to an Intermediate Care Unit were followed-up for 4 months regarding their drug therapies. Medical prescriptions were reviewed daily on the basis of patients' clinical conditions, with the view to identify opportunities for optimization of drug therapies, contributing to safer prescribing, reduced discomfort and correct and rational use of drugs.
