RESUMO
PURPOSE: Glaucomatous eyes with disc hemorrhage (DH) have a greater risk of paracentral visual field (VF) loss. However, not every DH eye presents with parafoveal scotoma (PFS), and contributing factors are still to be determined. In the present study, we investigated clinical and ocular factors associated with the presence of PFS in glaucomatous eyes with DH. METHODS: A case-control study was carried out. One hundred thirty glaucomatous patients with DH were enrolled. They were divided into two groups based on two reliable 24-2 VF tests: those with PFS (defined as ≥3 adjacent points with p < 5% within the central 10 degrees of fixation, ≥1 point with p < 1% lying at the innermost paracentral points, in the same hemifield) and those without PFS. Clinical and ocular data from the time of DH detection were compared between groups. Factors associated with the presence of PFS were investigated through logistic regression. RESULTS: The PFS group had a higher prevalence of Caucasian patients (82 vs. 47%; p < 0.01). Eyes with PFS had a more negative spherical equivalent and worse VF mean deviation (MD) index (p ≤ 0.01). There was a marginally significant intraocular pressure (IOP) difference between eyes with (15 mmHg) and without PFS (18 mmHg) at the time of DH detection (p = 0.10). Univariable analysis revealed PFS to be significantly associated with Caucasian race (OR, 3.02; p = 0.004), myopia (<-3 diopters; OR, 3.44; p = 0.039), and lower IOP (≤16 mmHg; OR, 2.10; p ≤ 0.047). Multivariable analysis, controlling for VF MD, revealed that only Caucasian race and myopia (as a continuous or categorical variable) remained significant in this model (p ≤ 0.038). CONCLUSIONS: Caucasian race and the presence and magnitude of myopia were found to be significantly associated with the presence of PFS in glaucomatous eyes with DH. Our results may help clinicians in the identification and surveillance of these eyes at higher risk of central VF loss.

PURPOSE: To report a case of nocardial scleritis and to propose a logical treatment algorithm based on a literature review. OBSERVATIONS: It is important to suspect a nocardial infection when evaluating anterior unilateral scleritis accompanied by multiple purulent or necrotic abscesses, especially in male patients with a history of chronic ocular pain and redness, trauma inflicted by organic materials, or recent ophthalmic surgery. A microbiological investigation is essential. In positive cases, a direct smear reveals weakly acid-fast organisms or Gram-positive, thin, beading and branching filaments. Also, the organism (usually) grows on blood agar and Lowenstein-Jensen plates. An infection can generally be fully resolved by debridement of necrotic areas and application of topical amikacin drops accompanied by systemic sulfamethoxazole-trimethoprim. CONCLUSIONS AND SIGNIFICANCE: Together with the case report described, we review data on a total of 43 eyes with nocardial scleritis. Our proposed algorithm may afford a useful understanding of this sight-threatening disease, facilitating easier and faster diagnosis and management.
RESUMO
OBJECTIVE: To describe the clinical characteristics, laboratory data, and clinical outcomes of patients with and without sepsis admitted to the ICU of a private hospital in the city of Salvador, Brazil, and to identify clinical variables related to a worse prognosis in those with sepsis. METHODS: This was a longitudinal study including all patients admitted to the general ICU of the Hospital Português, in the city of Salvador, Brazil, between June of 2008 and March of 2009. At ICU admission, two groups of patients were identified: with sepsis and without sepsis. Epidemiological, clinical and laboratory data were collected, and the Acute Physiology and Chronic Health Evaluation II (APACHE II) score was calculated. RESULTS: Of the 144 patients in the study, 29 (20.1%) had sepsis. Among the patients with sepsis, males accounted for 55.2%, the mean age was 73.1 ± 14.6 years, and the mean APACHE II score was 23.8 ± 9.1, compared with 36.3%, 68.7 ± 17.7 years, and 18.4 ± 9.5, respectively, among those without sepsis. There were significant associations between a diagnosis of sepsis and the following variables: APACHE II score; in-hospital mortality; ICU mortality; HR; mean arterial pressure; hematocrit level; white blood cell count; and antibiotic use. The use of life support measures and lower hematocrit levels were associated with a worse prognosis in the patients with sepsis. CONCLUSIONS: The patients diagnosed with sepsis presented worse clinical outcomes, probably due to their greater severity. Hematocrit level was the only variable that was a predictor of mortality risk in the patients with sepsis.

OBJETIVO: Descrever as características clínicas, os dados laboratoriais e o desfecho clínico de pacientes sépticos e não sépticos admitidos em UTI de um hospital privado na cidade de Salvador, Bahia, e identificar variáveis clínicas relacionadas ao pior prognóstico dos pacientes sépticos. MÉTODOS: Foi realizado um estudo longitudinal que incluiu todos os pacientes admitidos na UTI geral do Hospital Português, Salvador (BA), entre junho de 2008 e março de 2009. Na admissão na UTI, dois grupos de pacientes foram identificados: sépticos e não sépticos. Foram coletados dados epidemiológicos, clínicos e laboratoriais, e o escore Acute Physiology and Chronic Health Evaluation II (APACHE II) foi calculado. RESULTADOS: Dos 144 pacientes do estudo, 29 (20,1 por cento) eram sépticos. Entre os pacientes sépticos, 55,2 por cento eram do sexo masculino, a média de idade foi de 73,1 ± 14,6 anos, e a média do escore do APACHE II foi de 23,8 ± 9,1. No grupo não séptico, 36,3 por cento eram do sexo masculino, a média de idade foi de 68,7 ± 17,7 anos, e a média do escore do APACHE II foi de 18,4 ± 9,5. Houve associações estatisticamente significantes entre o diagnóstico de sepse e as seguintes variáveis: escore do APACHE II, mortalidade na UTI, mortalidade hospitalar, FC, pressão arterial média, valor de hematócrito, contagem de leucócitos e uso de antibioticoterapia. O uso de medidas de suporte e valores reduzidos de hematócrito se relacionaram com um pior prognóstico entre os pacientes sépticos. CONCLUSÕES: Os pacientes diagnosticados com sepse apresentaram piores desfechos clínicos, provavelmente por causa de sua maior gravidade. O nível de hematócrito foi a única variável capaz de predizer o risco de morte entre pacientes sépticos.
