Purtscher-like retinopathy in a paediatric patient with haemolytic uraemic syndrome: A case report and literature review.

An 8-year-old boy presented with fever, vomits, bloody diarrhoea, and blurred vision. The patient was diagnosed with Haemolytic Uraemic Syndrome (HUS) due to the symptoms and a positive Verotoxin stool test. Funduscopic examination showed retinal involvement in both eyes, peri-papillary paleness, retinal haemorrhages, and soft "Purtscher Fleckens" exudates.

[Laser treatment for retinopathy of prematurity in 27 public services of Argentina].

Introduction: Retinopathy of prematurity may lead to partial loss of vision and blindness; laser photocoagulation is the elective treatment, but universal access to it is not yet guaranteed in Argentina.

Objectives: To estimate prevalence of children requiring laser for retinopathy, their clinical and demographic characteristics, place of origin and place of treatment. POPULATION, MATERIAL AND METHOD: Observational, descriptive and retrospective study.

[Epidemiology of retinopathy of prematurity in public services from Argentina during 2008].

Introduction: Increasing survival of preterm newborns and current care deficits result in high rates of retinopathy of prematurity (ROP), affecting patients with higher birth weight (BW) and gestational age (GA) than those at developed countries; unusual cases (UC) and missed opportunities (MO) are reported.

Objective: To describe epidemiology of ROP during 2008 compared with the previous year. POPULATION, MATERIAL AND METHOD: Observational, descriptive and retrospective study.

[Retinopathy of prematurity in the XXI century in a developing country: an emergency that should be resolved].

Introduction: Retinopathy of prematurity (ROP) is the first cause of childhood blindness in Argentina and is reaching epidemic proportions. To gain greater insight into the issues involved in this epidemic, we analyzed the characteristics of the infants referred for treatment of very severe ROP to the Dr. Juan P.

Origins of highly mosaic mycobacteriophage genomes.

Bacteriophages are the most abundant organisms in the biosphere and play major roles in the ecological balance of microbial life. The genomic sequences of ten newly isolated mycobacteriophages suggest that the bacteriophage population as a whole is amazingly diverse and may represent the largest unexplored reservoir of sequence information in the biosphere. Genomic comparison of these mycobacteriophages contributes to our understanding of the mechanisms of viral evolution and provides compelling evidence for the role of illegitimate recombination in horizontal genetic exchange.

Cognitive and performance-based treatments for panic attacks in people with varying degrees of agoraphobic disability.

Compared the effectiveness of cognitive therapy and performance-based exposure as treatments for panic attacks. Subjects were 48 panicky individuals selected without regard to agoraphobic disability, and who varied widely in that respect. Subjects were assigned randomly to either cognitive treatment, performance-based exposure treatment, a combined cognitive/performance treatment, or a no-treatment control condition.

Generalization of therapeutic changes in agoraphobia: the role of perceived self-efficacy.

Investigated the extent and mechanisms of therapeutic generalization across distinct areas of agoraphobic dysfunction. Twenty-seven severe agoraphobics were each given performance-based treatment for some phobic areas while leaving their other phobias untreated. Behavioral tests revealed that (a) the treated phobias improved significantly more than the untreated (transfer) phobias, (b) the transfer phobias improved significantly more than control phobias, and (c) the transfer benefits were highly variable within and between subjects.
