Bronchiolitis. Analysis of 10 consecutive epidemic seasons

Bronchiolitis is the leading cause of hospitalization in infants under 12 months. Our aims were to analyze epidemiological characteristics of infants with bronchiolitis over 10 consecutive seasons and to evaluate whether there are any clinical differences between infants hospitalized for bronchiolitis during epidemic peak months and infants in non-peak months. We enrolled consecutive enrolled 723 previously healthy term infants hospitalized at the Paediatric Emergency Department, "Sapienza" University of Rome over the period 2004-2014. Fourteen respiratory viruses were detected from nasopharyngeal aspirates by molecular methods. Clinical and demographic data were extracted from clinical charts. Viruses were detected in 351 infants (48.5%): RSV in 234 (32.4%), RV in 44 (6.1%), hBoV in 11 (1.5%), hMPV in 12 (1.6%), co-infections in 39 (5.4%), and other viruses in 11 (1.5%). Analyzing the 10 epidemic seasons, we found higher incidence for bronchiolitis every 4 years with a peak during the months December-January. Infants hospitalized during peak months had lower family history for asthma (P = 0.003), more smoking mothers during pregnancy (P = 0.036), were slightly higher breastfed (0.056), had lower number of blood eosinophils (P = 0.015) and had a higher clinical severity score (P = 0.017). RSV was detected mostly during peak months, while RV was equally distributed during the seasons. We found some variations in bronchiolitis incidence during epidemics, and discriminative characteristics in infants hospitalized for bronchiolitis during peak months and in non-peak months, that might reflect two different populations of children.

Characteristics of people living in Italy after a cancer diagnosis in 2010 and projections to 2020

BACKGROUND: Estimates of cancer prevalence are widely based on limited duration, often including patients living after a cancer diagnosis made in the previous 5 years and less frequently on complete prevalence (i.e., including all patients regardless of the time elapsed since diagnosis). This study aims to provide estimates of complete cancer prevalence in Italy by sex, age, and time since diagnosis for all cancers combined, and for selected cancer types. Projections were made up to 2020, overall and by time since diagnosis. METHODS: Data were from 27 Italian population-based cancer registries, covering 32% of the Italian population, able to provide at least 7 years of registration as of December 2009 and follow-up of vital status as of December 2013. The data were used to compute the limited-duration prevalence, in order to estimate the complete prevalence by means of the COMPREV software. RESULTS: In 2010, 2,637,975 persons were estimated to live in Italy after a cancer diagnosis, 1.2 million men and 1.4 million women, or 4.6% of the Italian population. A quarter of male prevalent cases had prostate cancer (n\u2009=\u2009305,044), while 42% of prevalent women had breast cancer (n\u2009=\u2009604,841). More than 1.5 million people (2.7% of Italians) were alive since 5 or more years after diagnosis and 20% since 6515 years. It is projected that, in 2020 in Italy, there will be 3.6 million prevalent cancer cases (+\u200937% vs 2010). The largest 10-year increases are foreseen for prostate (+\u200985%) and for thyroid cancers (+\u200979%), and for long-term survivors diagnosed since 20 or more years (+\u200945%). Among the population aged 6575 years, 22% will have had a previous cancer diagnosis. CONCLUSIONS: The number of persons living after a cancer diagnosis is estimated to rise of approximately 3% per year in Italy. The availability of detailed estimates and projections of the complete prevalence are intended to help the implementation of guidelines aimed to enhance the long-term follow-up of cancer survivors and to contribute their rehabilitation need

Colorectal cancer survival in the USA and Europe: a CONCORD high-resolution study.

OBJECTIVES: To assess the extent to which stage at diagnosis and adherence to treatment guidelines may explain the persistent differences in colorectal cancer survival between the USA and Europe. DESIGN: A high-resolution study using detailed clinical data on Dukes' stage, diagnostic procedures, treatment and follow-up, collected directly from medical records by trained abstractors under a single protocol, with standardised quality control and central statistical analysis. SETTING AND PARTICIPANTS: 21 population-based registries in seven US states and nine European countries provided data for random samples comprising 12 523 adults (15-99 years) diagnosed with colorectal cancer during 1996-1998. OUTCOME MEASURES: Logistic regression models were used to compare adherence to 'standard care' in the USA and Europe. Net survival and excess risk of death were estimated with flexible parametric models. RESULTS: The proportion of Dukes' A and B tumours was similar in the USA and Europe, while that of Dukes' C was more frequent in the USA (38% vs 21%) and of Dukes' D more frequent in Europe (22% vs 10%). Resection with curative intent was more frequent in the USA (85% vs 75%). Elderly patients (75-99 years) were 70-90% less likely to receive radiotherapy and chemotherapy. Age-standardised 5-year net survival was similar in the USA (58%) and Northern and Western Europe (54-56%) and lowest in Eastern Europe (42%). The mean excess hazard up to 5 years after diagnosis was highest in Eastern Europe, especially among elderly patients and those with Dukes' D tumours. CONCLUSIONS: The wide differences in colorectal cancer survival between Europe and the USA in the late 1990s are probably attributable to earlier stage and more extensive use of surgery and adjuvant treatment in the USA. Elderly patients with colorectal cancer received surgery, chemotherapy or radiotherapy less often than younger patients, despite evidence that they could also have benefited

Lower incidence rates but thicker melanomas in Eastern Europe before 1992: A comparison with Western Europe

The objective of this study was to investigate the epidemiology of melanoma across Europe with regard to Breslow thickness and body-site distribution. Incidence data from Cancer Incidence in 5 Continents and the EUROCARE-melanoma database were used: 28 117 melanoma cases from 20 cancer registries in 12 European countries, diagnosed between 1978 and 1992. Regression analysis and general linear modelling were used to analyse the data. Melanomas in Eastern Europe were on average 1.4 mm thicker (P<0.05) than in Western Europe and appeared more often on the trunk. From 1978 to 1992, their Breslow thickness had decreased in Western but not Eastern Europe. There was a latitude gradient in incidence, with highest rates in southern regions in Eastern Europe and an inverse gradient in Western Europe, with highest rates in the North. Mortality:incidence ratios were less favourable in southern parts across Europe, especially in Eastern Europe. If Eastern European populations copy the sunbathing behaviour of the West it is likely that in the near future a higher melanoma incidence can be expected there

VACTERL association and maternal diabetes: A possible causal relationship?

BACKGROUND: Some factors(s)/features(s) of maternal insulin-dependent diabetes mellitus are considered common human teratogens. Although the variable association of cardiac, renal, and skeletal anomalies are commonly observed in infants from diabetic mothers, the relationship between VACTERL (i.e., the association of vertebral and cardiac defects, tracheo-esophageal fistula, renal/radial malformations, and other limb anomalies) and maternal diabetes has not been sufficiently emphasized in the literature. CASE: We report on a 3-year-old boy presenting with a constellation of blastogenetic malformations strongly suggestive of VACTERL association. His mother was affected by insulin-dependent diabetes since she was 7 years old and pregnancy history disclosed very high glucose and HbA1c levels, especially during the first 2 gestational months. CONCLUSIONS: In an attempt to properly counsel the parents, we reviewed the literature and identified four additional patients with VACTERL and first trimester exposure to maternal diabetes mellitus. Although this evidence does not strongly support a causal relationship between these two conditions, additional arguments may substantiate this hypothesis. The pathogenesis of diabetic embryopathy in relation to the VACTERL phenotype is also discussed

Persistent esophagotrachea: Description of a case

Esophagotrachea is the most severe form of laryngo-tracheo-esophageal cleft. This congenital anomaly is due to the anomalous differentiation of the primitive cephalic gut into trachea and esophagus. We present a case of a new born female with a common tracheoesophageal canal up to the carina. Atresia ani, a vulvo-vestibular fistula, sacral ipoplasia and others associated anomalies were also present. The baby underwent surgery after a laringo-tracheoscopy and a barium study of the esophagus. The prognosis of this extremely rare malformation is generally poor and the baby died on the fifth day after surgery for a serious ipertensive pneumothorax

Respiratory distress in newborn: evaluation of chest X-rays

We discuss the anatomic and pathophysiological patterns of preterm and term newborn. Particular attention is directed to technical artefacts relating to the interpretation of chest radiography. We analyze the reading of chest X-Ray of preterm with low birth weight and poor lung maturation. Are also taken into account X-Ray features relating to alveolar "recruitment" and radiographic changes after surfactant's administration. We highlight the most important paintings of bruncopulmonary dysplasia and its evolution. The most frequent neonatal pulmonary inflammation and thoraco-pulmonary malformation, that may affect more the neonatologist, are mentioned. We discuss the new diagnostic approach with non invasive techniques (ultrasound) in the neonatal distress. Some easily recognizable congenital heart disease are finally describes

Vertebral fractures and increased sensitivity to corticosteroids in a child with ulcerative colitis: successful of pamidronate

Increased risk of osteoporosis and fractures has been reported in patients with inflammatory bowel disease (IBD) primarily because of the inflammatory process itself and corticosteroid therapy (1,2). Vertebral fractures (VF) have rarely been reported in children with IBD, and only in the case of Crohn disease (CD) (3). We describe a case of vertebral compression fractures complicating the course of ulcerative colitis (UC) in a 7-year-old girl with increased sensitivity to corticosteroids
