Objectives: To describe maternal and fetal adverse effects, in particular cardiorespiratory, of nifedipine as tocolytic, as well as effects on hemodynamic parameters., Materials and Methods: A retrospective evaluative study describing the use of nifedipine as tocolytic at CHU Sainte-Justine in Montreal. Demographic data as well as maternal blood pressure and adverse effects, and maternal and fetal heart rate were collected from medical records of women treated with nifedipine following our tocolysis protocol between January 1st 2004 and March 1st 2007., Results: The medical records of 213 pregnant women were included in the study. Cardiorespiratory adverse effects were noted in 69 (32.4%); of these, 19 (8.9%) had serious cardiorespiratory adverse events, including 6 acute pulmonary edema or overload. Mean maternal systolic and diastolic blood pressures were significantly decreased and mean maternal and fetal heart rates were significantly increased after the bolus dose. Other adverse effects were reported for 100 (46.9%) women., Conclusion: Nifedipine may cause cardiorespiratory adverse effects warranting a close monitoring., (Copyright © 2014 Elsevier Masson SAS.

We review a different way of teaching medicine and pediatrics which balances theory and clinical training for undergraduate, postgraduate and during continuing education. We also discuss the role of the teacher. We recommend better evaluation of students and teacher assessments. We discuss the discrepancies and the harmonization of all Institutions involved in pediatric education. We analyze the model of teaching medicine and pediatrics in the Province of Quebec, Canada. We introduce advices on the application of skills in a pediatrics training program.

Aims: To evaluate the prevalence of positive tuberculin skin tests (TST) in internationally adopted and immigrant children. To identify risk factors for positive TST in these populations., Methods: The study was a retrospective medical record review in a tertiary care pediatric hospital. All children evaluated at the International Adoption and Immigrant Health Clinic of CHU Sainte-Justine in Montreal, Canada, between 01-01-1998 and 31-12-2001 were included. Demographic and anthropometrical data, BCG vaccination, TST, chest X-ray results and treatment were extracted from the medical records of the patients and analyzed. Positive TST was defined as induration = 10 mm, 48 to 72 hours after injection of five tuberculin units of purified protein derivate., Results: Our population included 670 children: 112 immigrants and 558 adoptees. Median age was 6.9 years for immigrants and 1.1 years for adopted children. Overall incidence of positive TST was 12.2% in our cohort: 31% in the immigrant and 8% in the adopted children groups. There was one case of active tuberculosis. Older age on arrival in Canada and BCG vaccination were identified as risk factors for positive TST in our multivariate model. For each one-year increase in age on arrival in Canada, there was a 1.2 times greater risk for positive TST., Conclusions: Latent tuberculosis is a frequent problem in foreign-born children. The higher incidence in immigrant children can be explained by older age on arrival.

Objectives: To examine the epidemiology, clinical characteristics and outcomes in a cohort of children with acute rheumatic fever (RF) over the past 27 years in Montreal., Methods: The medical records of patients younger than 18 years of age hospitalized and diagnosed with RF in Montreal between January 1979 and December 2005 were reviewed., Results: Among the initial 134 charts selected, 36 children were already followed-up for chronic RF and the remaining 98 patients (51 % females) who fulfilled the Jones criteria for acute RF were included in the analysis. The mean age at diagnosis was 10.1 +/- 3.0 years (range: 3-17). Over the 27-year study period, there was a mean incidence of 3.6 patients/year without peaks, but onset occurred in the last 15 years in almost two-thirds of the patients. Forty-nine percent of the patients were Canadian-born non-aboriginal (CbnA) and the remaining patients were Canadian-born aboriginal (CbA) or foreign-born (Fb). Carditis was diagnosed in 73 % of the patients and Sydenham's chorea in 49 %. Of the CbnA children, 39 % had carditis compared with 61 % of children from other ethnic groups (P = 0.003). However, the form of presentation was chorea in 69 % of CbnA children vs. 31 % of children from other ethnic groups (P < 0.001). No deaths were attributable to acute RF although 2 % of the patients relapsed during the study period. Severe cardiac sequelae requiring valve replacements occurred in 6.1 %., Conclusion: The incidence of acute RF in Montreal was low but consistent over the 27-year study period. Clinical presentation varied depending on ethnicity.

Background: With the advent of liver transplantation the outcome of children with biliary atresia (BA) has improved. Is Kasai hepatic portoenterostomy (KHPE) still a valuable option for the treatment of these patients?, Methods: From 1974 to 1998, 77 patients with biliary atresia have been treated at our institution: 50 girls and 27 boys., Results: Seventy-four patients had a KHPE, and 3 patients had no KHPE because of delay in diagnosis. A total of 65 of 74 patients (88%) had undergone KHPE type I, 4 patients (5.4%) KHPE type II, 3 patients (4%) had a Suruga modification, and 2 patients (2.6%) had a portocholecystostomy. Among the 74 patients, 11 were lost to follow-up and their cases were considered failures. Seventeen of our patients are alive at long-term follow-up after KHPE. Among the 77 patients, 33 (43%) had an orthotopic liver transplantation (OLT). Successful KHPE patients underwent transplant at a mean age of 9 years, and KHPE failed at a mean age of 11 months. A total of 25 of 77 (32%) of patients are alive thanks to OLT. In the cohort, the overall survival rate for the KHPE plus OLT is 42 of 77 (55%). Mortality and morbidity rates were more frequent among the younger patients who had early OLT after KHPE failure. In our series, overall survival rate was improved when the patient had a successful KHPE (P < .001)., Conclusions: Kasai hepatic portoenterostomy (KHPE) continues to be a valuable procedure in the treatment of infants with biliary atresia (BA). Successful KHPE permits transplantation at an age at which mortality and morbidity are decreased leading to a better outcome.

A diagnosis of endocarditis was made in 37 patients (three days to 21 years old) on the basis of the following: histology in 11; at least two positive blood cultures in patients with underlying cardiac disease in 22; less than two positive blood cultures, vegetations seen at echocardiography and a suggestive clinical syndrome in four. Twenty-six patients had primary endocarditis (17 with pre-existing cardiopathy, nine with normal hearts). The 11 others developed secondary endocarditis following heart surgery (early onset in six, late onset in five). The mean delay before diagnosis was prolonged 35.8 days. The clinical and laboratory findings included weakness in 36 patients, fever in 35, new or modified heart murmur in 14, positive blood cultures in 30, anemia in 12, high white blood cell count in 15, increased sedimentation rate in 14, and positive echocardiogram in 11. Etiologic agents isolated were: streptococci in 17, staphylococci in seven, miscellaneous germs in eight, and aspergillus in two. Mortality was greater in patients less than one year old, infected with aspergillus or without underlying heart disease. The present study suggests that childhood endocarditis remains uncommon but presents a poor prognosis with a mortality of 27% and a morbidity of 85.7%.
