Comparative Study
Teaching public health in undergraduate medical courses: a case study in three universities in Paraná.
Historically, different concepts of public health have influenced both the specific teaching in this field and its participation in general physician training. Starting from this assumption, the objective of this paper was to study how public health has been taught in undergraduate medical courses, focusing on structure and on how this has affected curriculum design in three universities in the State of Paraná, Brazil. ⋯ Regardless of the nature of the university, the administrative and academic setup of the course and of the different ways of incorporating teachers, Public Health is present and takes on considerable relevance for medical training, even if it does not constitute a linking thread within undergraduate medical courses.

Homeopathy is a therapeutic system that uses small doses of substances to stimulate autoregulatory and self-healing processes. The aim of this study was to investigate the prevalence of the use of homeopathy by the population of Montes Claros, Brazil, and the socioeconomic profile of users. ⋯ The prevalence of the use of homeopathy found here was less than that reported in other countries. People with higher income and schooling levels used homeopathy more frequently. There was higher prevalence among women. Most users declared themselves satisfied with the treatment received.

Hydrofluoric acid (HF) is widely used in industry and at home. Severe lesions can occur after contact with highly concentrated solutions, leading to tissue necrosis and bone destruction. Specific treatment is based on neutralization of fluoride ions with calcium or magnesium solutions. ⋯ Intra-arterial calcium gluconate might be considered for finger burns caused by concentrated HF. Complete recovery of wounded fingers can be achieved with this technique even if started 24 hours after the exposure. However, controlled clinical trials are needed to confirm the effectiveness and safety of this intervention.

Parathyroid cysts are rare clinical and pathological entities, with less than 300 cases reported. The inferior parathyroid glands are most commonly involved, with left-side predominance. Parathyroid cysts may be functional or nonfunctional, depending on their association with hypercalcemia. ⋯ A 25-year-old man presented a palpable asymptomatic left-side neck mass. Ultrasound revealed a cystic structure contiguous with the left thyroid lobe. Serum ionic calcium was normal. The patient underwent left thyroid lobectomy plus isthmectomy with excision of the cyst. The histological findings revealed a parathyroid cyst. Parathyroid cysts typically present as asymptomatic neck masses, and surgical excision appears to be the treatment of choice.

The methodology and relevance of articles are among the keystones for promoting their citation and increasing journals' impact factors. Study designs appropriate for answering the questions and adequate sample sizes have the aim of reducing the risk of bias. This study evaluated the articles published in two Brazilian journals of orthopedics and sports medicine that were recently indexed in the ISI Web of Science, regarding study design, sample size calculation, randomization and blinding. ⋯ Publication of studies of good methodological quality other than review and experimental studies should be strongly encouraged among Brazilian journals, with the aim of increasing their citation and therefore their impact factor.
