Antiretroviral treatment in pregnancy: a six-years perspective on recent trands in prescription patterns, viral load suppression, and pregnancy outcomes.

The aim of the study was to describe the recent trends in antiretroviral treatment in late pregnancy and the sociodemographic changes among pregnant women with HIV over the last 6 years. Data from the National Program on Surveillance on Antiretroviral Treatment in Pregnancy in Italy were grouped per calendar year, and changes in antiretroviral treatment, population characteristics, maternal immunovirologic status and newborn clinical parameters were analyzed. A total of 981 HIV-infected mothers who delivered between 2002 and 2008 were evaluated. The proportion of women receiving at least three antiretroviral drugs at delivery increased significantly from 63.0% in 2002 to 95.5% in 2007-2008, paralleled by a similar upward trend in the proportion of women who achieved complete viral suppression at third trimester (from 37.3 in 2002 to 80.9 in 2007-2008; p < 0.001). The co-formulation of zidovudine plus lamivudine remained the most common nucleoside backbone in pregnancy, even if a significant increase in the use of tenofovir plus emtricitabine was observed in more recent years. Starting from 2003, nevirapine prescription declined, paralleled by a significant rise in the use of protease inhibitors (PI), which were present in more than 60% of regimens administered in 2007-2008. Nelfinavir was progressively replaced by ritonavir-boosted PIs, mainly lopinavir. No significant changes in preterm delivery, Apgar score, birth weight, and birth defects were observed during the study period, and the rate of HIV transmission remained below 2%. These data demonstrate a significant evolution in the treatment of HIV in pregnancy. Constant improvements in the rates of HIV suppression were observed, probably driven by the adoption of stronger and more effective regimens and by the increasing options available for combination treatment

Is heel prick as safe as we think?

Purulent lymphadenitis is rare in newborn and is associated with prematurity and invasive procedure. Neonatal staphylococcal infections due to skin interruption during intramuscular vitamin K administration and national metabolic screening programme (heel prick or Guthrie card test) have been already previously described. This is a report of a premature infant who developed an inguinal adenitis as a result of late complications from heel pricks. The diagnosis was made on clinical grounds and confirmed by ultrasound scans. Staphylococcus aureus was isolated. Bacteremia did not occur and the lymphadenitis had a complete resolution with antimicrobial therapy. The heel prick is a well-established procedure in neonatal practice, nevertheless it is not risk-free. The attention to signs of infections is important to avoid complications such as purulent lymphadenitis, abscess formation and septicemia. Best practice prevention and control in minimising the risk of infections are the most important intervention to prevent this complication

Efficacy of over-the-counter immunostimulants in the prevention of paediatric recurrent acute respiratory tract infections. Criticisms and pitfalls of available metanalyses

Preschool children frequently suffer from acute respiratory tract infections (ARTI). Immunostimulants (ISs) are often administered to reduce their impact. This study aimed to establish the efficacy of ISs in the prevention of pediatric ARTI through the analysis of systematic reviews (SRs). We explored Medline database in October 2010 limiting our search to SRs, that included studies on the effectiveness of ISs in the prevention of pediatric ARTI. Six SRs with meta analysis (MA) were found. The studies included showed a low methodological quality and a high statistical heterogeneity. All papers published on journals with impact factor > 1 and a Jadad score > 3 reviewed the efficacy of OM-85. The number needed to treat (NNT) was between 2 and 11, depending on the setting. CONCLUSIONS: Pediatric ARTI are a social and health care problem. When they impair the quality of life of the family a course of OM-85 might be warranted. Although scientific knowledge of clinicians may be improved by SRs, MA and aggregation of results may not always be the best way to accomplish thi

Brain CT scan for pediatric minor accidental head injury. An Italian experience and review of literature

PURPOSE: Every year 300,000 children with accidental head trauma are admitted to Italian emergency departments. Our aims were: (1) to describe patients with minor traumatic brain injury who were admitted to pediatric departments and underwent CT, and (2) to analyze the appropriateness of management according to current guidelines. METHODS: We retrospectively analyzed patients with minor head injury (median age 4.5 years, range 1 month to 16 years) who were admitted to the pediatric department of the Catholic Medical School of Rome, from January 2005 to September 2010, who performed head CT. Univariate analysis was performed using the Fisher's exact test. Multivariate analysis was performed by logistic regression. RESULTS: One hundred and seventy-four patients were enrolled in the study. Fifty-four patients (31%) had pathological CT findings. Eight patients underwent neurosurgical treatments. Vomiting was the only symptom significantly prevalent in the infant group, compared to the children group (10.7% vs. 38.9%, p = 0.007), while loss of consciousness in the children group (50.0% vs. 25.0%, p = 0.040). The relationship between scalp swelling and CT abnormalities was statistically significant in the entire population. The incidence of head abnormalities was significantly higher in children with abnormal CT (92.6% vs. 72.5%). CONCLUSIONS: The best way to manage children with minor head trauma is still matter of debate. Loss of consciousness and scalp swelling are risk factors predicting brain injury that deserve CT control. The radiation risks posed by CT scanning in children must be balanced by the benefits. We believe that even though CT scans may be clinically unnecessary in many cases, the rate of scanning is justified by the even limited number of abnormalities which require neurosurgical treatment

Celiac disease: what's new about it?

In the present review we will try to summarize the clinical and diagnostic features of celiac disease (CD) as well as the new findings on extraintestinal manifestation. CD is an immune-mediated enteropathy caused by a permanent gluten intolerance. In the last years, the diagnosis is becoming more and more frequent because of the recognition of 'new' symptoms and associated extraintestinal manifestations. Classical CD is dominated by symptoms and sequelae of gastrointestinal malabsorption. In the 'atypical forms', the extraintestinal features usually predominate, with few or no gastrointestinal symptoms. Silent CD refers to asymptomatic patients with a positive serologic test and villous atrophy on biopsy. This form is detected by screening of high-risk individuals, or villous atrophy occasionally may be detected by endoscopy and biopsy conducted for another reason. The potential form is diagnosed in groups at risk including relatives of celiac patients, Down syndrome and autoimmune diseases. Latent CD is defined by positive serological tests but not histological changes on biopsy. These individuals are asymptomatic, but later may develop symptoms and/or histological alterations. Recognition of atypical manifestations of CD is very important because many cases can remain undiagnosed with an increased risk of long-term complications. 2008 S. Karger AG, Basel

Chromosome 9p deletion syndrome and sex reversal: novel findings and redefinition of the critically deleted regions.

Deletions of the short arm of chromosome 9 are associated with two distinct clinical entities. Small telomeric 9p24.3 deletions cause genital anomalies in male subjects, ranging from disorder of gonadal sex to genital differentiation anomalies, while large terminal or interstitial deletions result in 9p-malformation syndrome phenotype. The critical region for non-syndromic 46,XY sex reversal was assigned to a 1 Mb interval of chromosome 9p, extending from the telomere to the DMRT genes cluster. The 9p-syndrome was assigned to bands 9p22.3p24.1, but a phenotypic map has not been established for this condition, probably because of the lack of detailed molecular and/or phenotypic characterization, as well as frequent involvement of additional chromosome rearrangements. Here, we describe a unique patient with a small isolated 9p terminal deletion, characterized by array-CGH and FISH, who shows a complex phenotype with multiple physical anomalies, resembling the 9p-syndrome, disorder of sex development with gonadoblastoma, congenital heart defect and epilepsy. The observed deletion includes the 46,XY sex-reversal critical region, excluding the region so far associated with the 9p-syndrome. Genotype-phenotype correlations are tentatively established comparing our patient to seven other previously reported males with isolated terminal 9p deletions, finely defined at a molecular level. Our observations expand the 9p deletion clinical spectrum, and add significantly to the definition of a 9p-syndrome critical region
