Correlation between Epstein Barr virus antibodies, serum IgE and atopic disease

It is currently accepted that vinil infections may influence the development of atopy. In the present study we evaluated serum IgE levels as well as the prevalence of symptom-, indicative of utopic disease and EBV antibodies in 353 children aged from I month to 19 years. Antibodies against EBV were detected by immunofluorescence. IgE levels in serum were measured by en/. yme imimmoassay. Dividing ihe study population according to EBV seropositivity and age, we noted that the prevalence of high IgE levels (> 2 s. d.) was, in total, more frequent in the EBV negative (32. 9%) than in the positive subjects (27. 6%). Interestingly, this higher prevalence was found only in the groups aged under six, especially in the 7 to 29 month group, where it was statistically significant (p=0.037), whereas in the 6-19 year group the situation was reversed. Furthermore, selecting only the atopic children younger than 3 years of age with high IgE levels and clinical symptoms of atopy (wheezing and/or dermatitis) it was possible to demonstrate lower EBV seropositivity compared with the normal IgE controls for each group, even though these differences were not statistically significant. In conclusion, the results of our study suggest that, in our selected population, EBV infection in the first years of life is associated with a lower prevalence of high IgE levels.     

Impact of EGFR expression on colorectal cancer patient prognosis and survival.

BACKGROUND: Epidermal growth factor receptor (EGFR) is overexpressed in many types of cancers, especially colorectal cancer (CRC), and seems to reflect more aggressive histological and clinical behaviors. The aim of this study was to evaluate EGFR immunohistochemical reactivity in CRC biopsies, and to analyze its relationship with various histological and clinical characteristics and survival. PATIENTS AND METHODS: A composite EGFR score, obtained by multiplying the grade (% positive cells) by the intensity of labeling (0-9) was used to define patients with low or high EGFR expression whose clinicopathological features were then compared. Univariate tests and multivariate Cox proportional hazards model were applied for data analysis. RESULTS: Tissue sections from 150 CRC patients with a median follow-up of 40 months were examined. Median patient age at diagnosis was 70 years (range 38-89 years). EGFR reactivity was positive for 143 patients (97%) and high for 118 (80%). According to multivariate analysis, EGFR overexpression was significantly associated with tumor stage, with a higher percentage of EGFR overexpression in T3 than T4 (P=0.003) and not with overall survival. CONCLUSIONS: EGFR was overexpressed in this CRC patient population and was significantly associated with TNM (tumor-node-metastasis) stage T3. In the context of a new therapeutic strategy using EGFR-targeted therapies, although EGFR remains a controversial prognostic factor, this expression-stage association may play a crucial role in a decision to initiate an adjuvant treatment.     

Esophageal atresia: critical review of 10 years' experience

From January 1976 to October 1986, 107 cases of esophageal atresia (EA) were admitted to the Neonatal Surgical Unit of the Bambino Gesú Hospital of Rome; 86% of the children had a type III EA. Associated anomalies were present in 47%; they were multiple in 18%. Cardiological malformations were the most frequent followed by digestive, skeletal, urological, and chromosomal aberrations. Surgical treatment was attempted in all children except 3, who died before surgical correction, in an effort to perform an end-to-end anastomosis in a single layer through a transpleural approach. According to the results, children were divided into two groups of 50 patients each: group 1 (1976–1981); and group 2 (1981–1986). Anastomosis was possible in 69% of children (68.7% in group 1, 69.3% in group 2). After 1983, gastrostomy fell into gradual disrepute and a transanastomotic tube was used. Immediate complications were seen in 36.6% of cases; in no case did recurrence of the tracheoesophageal fistula occur. The overall mortality decreased from 50% (group 1) to 30% (group 2). In the two periods considered, the mortality according to Waterston's risk classes was 28.5% 5,8% (class A), 42.1% 11.7% (class B), 82.3% 68.7% (class C). Of a total of 41 deaths, 47% were due to severe associated malformations: bronchopneumopathy or prematurity seemed to have less importance in establishing the prognosis.Offprint requests to: P.

Vaccine prevention in perinatal health care: parents, children and professionals

Recent legislative texts have changed vaccinal policy and reinforced the role of midwives in vaccine prevention in perinatal healthcare. Quite as paediatricians and obstetricians-gynecologists, midwives can now prescribe and carry out, for the mothers, vaccines against rubella, tetanus, poliomyelitis, diphtheria, hepatitis B, influenza and whooping-cough and for the newborns vaccines against hepatitis B and tuberculosis. Concerning vaccinations, practitioners have to respect the vaccination calendar and a collaborative action is useful and necessary. These national guidelines are regularly updated when new vaccines and new recommendations come to light, for example for children (papillomavirus, tuberculosis, pneumococcus...), young adults (varicella, whooping-cough) and health professions in contact with very young children (varicella, measles, influenza and whooping-cough). The recent changes in tuberculosis prevention from routine vaccination of all newborn infants to selective vaccination lead to reinforce measures to detect the infants at higher risk, for them to be vaccinated before discharge at home. Midwives and nurses occupy a central place in family policy and become, with obstetricians-gynecologists and pediatricians, key actors for the effectiveness and the success of vaccine strategies in perinatal health.     

Dysplasie épithéliale ovarienne : mythe ou réalité ? Revue de la littérature

Ovarian epithelial dysplasia has been described in the ovarian surface epithelium by histologic, morphometric and nuclear profile studies. It could represent a potential precursor of ovarian malignancy in patients with genetic risk of ovarian cancer, although its natural history and progression to carcinoma are unpredictable. Diagnosis and identification of ovarian dysplasia would certainly be useful to understand the early steps of ovarian carcinogenesis. However, dysplasia in relation with ovulation induction seems to have a different pattern. We report dysplasia definitions and the current clinical management.     

Face rehabilitation for post-burn deformities

Severe post-burn sequelae of the face can result from deep initial burns or inappropriate (initial or secondary) treatment. They still remain a surgical challenge, leading to both aesthetic and functional diseases. The acute treatment is preventive, and usually consists in early split thickness skin grafts from the scalp, while full thickness skin grafts and local flaps are employed for the sequels. Our surgical treatment consists in scar replacement using expanded supraclavicular skin. Depending on the location of the scars and depending on available skin, surgical procedure can use expanded full thickness skin graft or expanded advancement flaps. Some “aesthetic” procedures like lipofilling, rhinoplasty or botulinum toxin can be performed in order to improve the final aspect. Good aesthetic and functional results are usually obtained if fundamental rules are respected: preservation of aesthetic units of the face, good management of skin availability. In any case, whatever techniques are employed, numerous surgical procedures and months of rehabilitation are necessary to achieve good cosmetic and functional results.     

Prospective multicenter study on epidemiology of acute kidney injury in the ICU: a critical care nephrology Italian collaborative effort (NEFROINT)

Acute kidney injury (AKI) is an independent risk factor for mortality in critically ill patients whose epidemiology has been made unclear in the past by the use of different definitions across various studies. The RIFLE consensus definition has provided a unifying definition for AKI leading to large retrospective studies in different countries. The present study is a prospective observational multicenter study designed to prospectively evaluate all incident admissions in 10 Intensive Care Units (ICUs) in Italy and the relevant epidemiology of AKI. A simple user-friendly web-based data collection tool was created with the scope to serve for this study and to facilitate future multicenter collaborative efforts. We enrolled 601 consecutive patients into the study; 25 patients with End-Stage Renal Disease were excluded leaving 576 patients for analysis. The median age was 66 (IQR 53-76) years, 59.4% were male, while median SAPS II and APACHE II scores were 43 (IQR 35-54) and 18 (IQR 13-24), respectively. The most common diagnostic categories for ICU admission were: respiratory (27.4%), followed by neurologic (17%), trauma (14.4%), and cardiovascular (12.1%). Crude ICU and hospital mortality were 21.7% and median ICU length of stay was 5 days (IQR 3, 14). Of 576 patients, 246 patients (42.7%) had AKI within 24 hours of ICU admission while 133 developed new AKI later during their ICU stay. RIFLE-initial class was Risk in 205 patients (54.1%), Injury in 99 (26.1%) and Failure in 75 (19.8%). Progression of AKI to a worse RIFLE class was seen in 114 patients (30.8% of AKI patients). AKI patients were older, with higher frequency of common risk factors. 116 AKI patients (30.6%) fulfilled criteria for sepsis during their ICU stay, compared to 33 (16.7%) of non-AKI patients (P<0.001). 48 patients (8.3%) were treated with renal replacement therapy (RRT) in the ICU. Patients were started on RRT a median of 2 (IQR 0-6) days after ICU admission. Among AKI patients, they were started on RRT a median of 1 (IQR 0-4) days after fulfilling criteria for AKI. Median duration of RRT was 5 (IQR 2-10) day. AKI patients had a higher crude ICU mortality (28.8% vs. non-AKI 8.1%, P<0.001) and longer ICU length of stay (median 7 days vs. 3 days [non-AKI], P<0.001). Crude ICU mortality and ICU length of stay increased with greater severity of AKI. Two hundred twenty five patients (59.4% of AKI patients) had complete recovery of renal function, with a SCr at time of ICU discharge which was ≤120% of baseline; an additional 51 AKI patients (13.5%) had partial renal recovery, while 103 (27.2%) had not recovered renal function at the time of death or ICU discharge. Septic patients had more severe AKI, and were more likely to receive RRT with less frequency of renal function recovery. Patients with sepsis had higher ICU mortality and longer ICU stay. The study confirms previous analyses describing RIFLE as an optimal classification system to stage AKI severity. AKI is indeed a deadly complication for ICU patients where the level of severity correlated with mortality and length of stay. The tool developed for data collection resulted user friendly and easy to implement. Some of its features including a RIFLE class alert system, may help the treating physician to collect systematically AKI data in the ICU and possibly may guide specific decision on the institution of renal replacement therapy.
