Adherence to secondary prophylaxis and disease recurrence in 536 Brazilian children with rheumatic fever

Background  

More than 15 million people worldwide have rheumatic fever (RF) and rheumatic heart disease due to RF. Secondary prophylaxis is a critical cost-effective intervention for preventing morbidity and mortality related to RF. Ensuring adequate adherence to secondary prophylaxis for RF is a challenging task. This study aimed to describe the rates of recurrent episodes of RF, quantify adherence to secondary prophylaxis, and examine the effects of medication adherence to the rates of RF in a cohort of Brazilian children and adolescents with RF.     

Severe congenital absence of skin in a preterm infant

A severe case of aplasia cutis congenita in a preterm infant is described. Although major problems with thermoregulation and fluid balance were anticipated, these parameters were relatively easy to control once the patient was stabilized. Meticulous skin care and rapid formation of a membranous-like fibrous tissue layer covering the denuded areas probably played an important role in minimizing excessive fluid and heat loss. The prognosis in aplasia cutis congenita is determined by the underlying associated anomalies, the severity of skin lesions and, in our case, the maturity of the infant who died from complications of prematurity.     

Iron supplement in pregnancy and development of gestational diabetes—a randomised placebo-controlled trial

Objective  To test the hypothesis that iron supplement from early pregnancy would increase the risk of gestational diabetes mellitus (GDM).
Design  Randomised placebo-controlled trial.
Setting  A university teaching hospital in Hong Kong.
Population  One thousand one hundred sixty-four women with singleton pregnancy at less than 16 weeks of gestation with haemoglobin (Hb) level between 8 and 14 g/dl and no pre-existing diabetes or haemoglobinopathies.
Methods  Women were randomly allocated to receive 60 mg of iron supplement daily ( n = 565) or placebo ( n = 599). Oral glucose tolerance tests (OGTTs) were performed at 28 and 36 weeks. Women were followed up until delivery.
Outcome measures  The primary outcome was development of GDM at 28 weeks. The secondary outcomes were 2-hour post-OGTT glucose levels, development of GDM at 36 weeks and delivery and infant outcomes.
Results  There was no significant difference in the incidence of GDM in the iron supplement and placebo groups at 28 weeks (OR: 1.04, 95% confidence interval [CI]: 0.7–1.53 at 90% power) or 36 weeks. Maternal Hb and ferritin levels were higher in the iron supplement group at delivery ( P < 0.001 and P = 0.003, respectively). Elective caesarean section rate was lower in the iron supplement group (OR: 0.58, 95% CI: 0.37–0.89). Infant birthweight was heavier ( P = 0.001), and there were fewer small-for-gestational-age babies in the iron supplement group (OR: 0.46, 95% CI: 0.24–0.85).
Conclusion  Iron supplement from early pregnancy does not increase the risk of GDM. It may have benefits in terms of pregnancy outcomes.     

Living with Marfan syndrome I. Perceptions of the condition

We present data from an exploratory study of 174 adults with Marfan syndrome regarding their cognitive perceptions of the condition as postulated by the self-regulatory model (Leventhal H, Benyamini Y, Brownlee S et al. In: Petrie KI, Weinman JA, eds. Perceptions of Health and Illness: Current Research and Applications. Amsterdam, The Netherlands: Harwood Academic, 1997: 19-45; Leventhal H, Nerenz DR, Steele DJ. In: Baum A, Taylor SE, Singer JE, eds. Handbook of Psychology and Health. Hillsdale, NJ: Lawrence Erlbaum Associates, 1984: 219-252). The vast majority of the respondents had adequate general knowledge about Marfan syndrome. Eighty-three percent of the respondents perceived Marfan syndrome as having had significant adverse consequences on their lives. Having striae, pain (sore joints), and depression were each independently correlated with this view. Fifty-eight percent of the respondents indicated that they felt they had low to moderate control over their condition, demonstrating variability. History of aortic dissection, pain (sore joints), and depressive symptoms were each negatively correlated with the view that Marfan syndrome is a curable/controllable condition. Moreover, approximately 28% view the condition as a lethal condition, whereas 67% view it as a serious condition. Forty-four percent of the cohort were found to have significant symptomatology of depression independent of beta- and Ca2+-channel blockade use. Respondents cited both advantages and disadvantages of being affected. Genetic counseling that addresses patients' perceptions of Marfan syndrome, and its associated pain, fatigue, and depressive symptoms, may enhance patient adaptation to the condition.     

Risk of cardiovascular thrombotic events after surgical castration versus gonadotropin-releasing hormone agonists in Chinese men with prostate cancer

We investigated the cardiovascular thrombotic risk after surgical castration (SC) versus gonadotropin-releasing hormone agonists (GnRHa) in Chinese men with prostate cancer. All Chinese prostate cancer patients who were treated with SC or GnRHa from year 2000 to 2009 were reviewed and compared. The primary outcome was any new-onset of cardiovascular thrombotic events after SC or GnRHa, which was defined as any event of acute myocardial infarction or ischemic stroke. The risk of new-onset cardiovascular thrombotic event was compared between the SC group and the GnRHa group using Kaplan–Meier method. Multivariate Cox regression analysis was performed to adjust for other potential confounding factors. A total of 684 Chinese patients was included in our study, including 387 patients in the SC group and 297 patients in the GnRHa group. The mean age in the SC group (75.3 ± 7.5 years) was significantly higher than the GnRHa group (71.8 ± 8.3 years) (P < 0.001). There was increased risk of new cardiovascular thrombotic events in the SC group when compared to the GnRHa group upon Kaplan–Meier analysis (P = 0.014). Upon multivariate Cox regression analysis, age (hazard ratio [HR] 1.072, 95% confidence interval [CI] 1.04–1.11, P< 0.001), hyperlipidemia (HR 2.455, 95% CI 1.53–3.93, P< 0.001), and SC (HR 1.648, 95% CI 1.05–2.59, P = 0.031) were significant risk factors of cardiovascular thrombotic events. In conclusion, SC was associated with increased risk of cardiovascular thrombotic events when compared to GnRHa. This is an important aspect to consider while deciding on the method of androgen deprivation therapy, especially in elderly men with known history of hyperlipidemia.     

Percutaneous endoscopic gastrostomy in children with cancer

We reviewed the clinical course of 32 children with cancer who received nutrition through a feeding tube placed percutaneously during gastroscopy (PEG). Their median age was 5.1 y (75%, range: 1.8-13.7 y, min: 3.5 mo) when the PEG was done 0.7-23 mo after diagnosis (median: 1.8 mo, 75%; range: 0.9-8 mo). Five of the children underwent bone marrow transplantation with the gastrostomy in place. There was a significant (p     

<Emphasis Type="Italic">Streptobacillus moniliformis</Emphasis> septic arthritis: a clinical entity distinct from rat-bite fever?

Background  

Streptobacillus moniliformis is a zoonotic agent associated with rodent contacts. Although it is more commonly reported to cause rat-bite fever with reactive arthritides, it can also lead to pyogenic infection of the joints.
