This study demonstrated that the smaller diameter XEN 45 gel implant is statistically effective in reducing IOP and medications in glaucoma patients with a low rate of complications.

Background: Viral respiratory tract infections (VRI) are a major reason for hospitalization in children younger than 5 years. A case control study was conducted to investigate the potential role of breastfeeding in protecting children <1 year of age from VRI. Methods: Patients admitted for a respiratory tract infections routinely underwent a nasopharyngeal aspirate, which was tested with an RT-PCR for 14 respiratory viruses. Hospitalized infants positive for viruses were enrolled as cases; healthy controls were enrolled among patients admitted for ultrasound hip screening. The effect of breastfeeding on pertussis was investigated through multivariable analysis. Results: We enrolled a total of 496 patients: 238 cases and 258 healthy controls. Among cases, eighty-six patients (36.1%) had a rinovirus, 78 (32.8%) an RSV, 22 (9.2%) an adenovirus, and 37 (15.5%) a coinfections with multiple viruses. The number of households was significantly higher in cases (mean in cases 4.5; mean 3.7 in controls, p < 0.001) and the proportion of infants having siblings (79% in cases vs. 43% in controls, p < 0.001). Proportion of smoking mothers was higher in cases than in controls (21.4 vs. 10.1%, p = 0.001). Among cases 44.5% were exclusively breastfed at symptoms onset vs. 48.8% of healthy controls. According to the multivariable analysis, being exclusively breastfed at symptom onset was associated with a higher risk of viral respiratory infection (3.7; 95% CI 1.64–8.41), however a longer breastfeeding duration was protective (OR 0.98; 95% CI 0.97–0.99). Also having at least one sibling was associated to a higher risk (OR 3.6; 95% CI 2.14–5.92) as well as having a smoking mother (OR 2.6; 95% CI 1.33–4.89). Conclusions: Breastfeeding remains a mainstay of prevention for numerous diseases and its protective role increases with duration. However, being breastfed when mothers carry a respiratory infection may increase the risk of transmission, acting as a proxy for closer contacts. In future studies, potential confounding variables as pattern of contacts with other individuals, should be taken into account.

Migraine is the most common type of chronic episodic headache. Several population-based family studies have suggested a strong genetic predisposition to migraine, especially migraine with aura (MA). Although several susceptibility loci have been identified, none of the numerous studies performed to date have led to the identification of a gene responsible for the more common forms of migraine. GABA-A receptors and their modulator sites seem to be involved in the pathophysiological events that underlie migraine. We report on clinical and molecular data from a total of 10 families with MA, in which MA segregates as an autosomal dominant trait and presents with homogeneous clinical features. After excluding linkage with the known candidate loci, we used a functional candidate approach and genotyped these families with markers from the 15q11-q13 genomic region, which contains the genes encoding GABA-A receptor subunits. Evidence of linkage was obtained with a parametric two-point linkage analysis (maximum LOD score of 5.56 at a recombination fraction of 0.001 for marker GABRB3) and was supported by multipoint analysis (maximum LOD score of 6.54 between markers D15S113 and D15S1019). The critical region spanned 3.6 Mb. These results provide the basis for further investigation of the hypothesized relationship between a GABA-A receptor dysfunction and migraine.

In Italy, no specific recommendation toward maternal pertussis immunization during pregnancy has been issued. However, vaccination during pregnancy will be likely integrated in the Italian immunization program in the future. In order to identify barriers to achieving a sufficient vaccination coverage during pregnancy, we investigated knowledge, attitude and practice toward pertussis vaccination during pregnancy through a web-based survey. A total of 343 Italian pregnant women (N = 164) and women in the postpartum period (N = 183) completed the online questionnaire. More than a half of the study population was uncertain regarding the benefits of the vaccination during pregnancy. Only 1.7% of women in the postpartum had received the vaccination during pregnancy, and 21% of pregnant women declared the intention to be vaccinated in pregnancy. Only 34% would accept the vaccination in the current or in a future pregnancy, if recommended by a physician, and a half would remain uncertain. Perceiving the vaccine as harmful for the fetus' development is associated to a decreased willingness to be vaccinated if recommended by a HCP, both in pregnant women (OR 0.25 p = 0.010 95% CI 0.09-0.72) and in women in the postpartum period (OR 0.32 p =  0.006 95% CI 0.15-0.72). Our study suggests that the vaccination recommendation by physicians might not be sufficient to adequately raise vaccination coverage against pertussis among Italian pregnant women. A combination of educational interventions and tailored communi-cation campaigns could be implemented to promote maternal immunization.
