Brief comments on three existing approaches for managing neonates at risk of early-onset sepsis

Background

Growing concerns regarding the adverse effects of antibiotics during the first days of life and the marked reduction in the incidence of early-onset sepsis (EOS) are changing the clinical practice for managing neonates at risk of EOS. Strategies avoiding unnecessary antibiotics while promoting mother-infant bonding and breastfeeding deserve to be considered.

Main body

We compare strategies for managing newborns at risk of EOS recommended by the American Academy of Pediatrics, which are among the most followed recommendations worldwide. Currently three different approaches are suggested in asymptomatic full-term or late preterm neonates: i) the conventional management, based on standard perinatal risk factors for EOS alone, ii) the neonatal sepsis calculator, a multivariate risk assessment based on individualized, quantitative risk estimates (relying on maternal risk factors for EOS) combined with physical examination findings at birth and in the following hours and iii) an approach entirely based on newborn clinical condition (serial clinical observation) during the first 48 h of life.

We discuss advantages and limitations of these approaches, by analyzing studies supporting each strategy. Approximately 40% of infants who develop EOS cannot be identified on the basis of maternal RFs or laboratory tests, therefore close monitoring of the asymptomatic but at-risk infant remains crucial. A key question is to know what proportion of babies with mild, unspecific symptoms at birth can be managed safely without giving antibiotics.

Conclusions

Both neonatal sepsis calculator and serial clinical observation may miss cases of EOS, and clinical vigilance for all neonates is essential There is a need to assess which symptoms at birth are more predictive of EOS, and therefore require immediate interventions, or symptoms that can be carefully reevaluated without necessarily treat immediately the neonate with antibiotics. Studies comparing strategies for managing neonates are recommended.

[Post-traumatic myo-arthropathy of the mandibular joint. Report of a case]

The author reports a case of post-traumatic myoarthropathy which was resolved through the search for a new centric ratio which was subsequently transformed in ICP with a varied vertical dimension. This was based on the assumption that post-traumatic intracapsular modifications impose this therapeutic objective given that they do not fall within the range of muscular adaptability.

[Apicoectomy: indications]

Chronic apical periodontitis and apical cyst are chronologically different expressions of a chronic, productive-type inflammatory process. Treatment, however, differs with cases. As X-ray diagnosis is generally impossible, endodontic treatment is the first therapeutic action required. If no remission is seen, surgery is necessary, with curettage in the event of apical integrity, and apicectomy otherwise.

[Ambulatory therapy with fosfomycin in dentistry and stomatology]

1-2 g/day or 3-4 g/day phosphomycin were administered per os to children and adults respectively for an average of 5.2 days in the outpatient treatment of 28 males and 18 females with parodontitis, gingivitis and dysodontiasis of bacterial origin. All patients presented swelling of the soft parts and 34 (74%) had hyperpyrexia. A clinical cure was obtained after 9 days in all cases. Fever lasted an average of 2.4 days and disappeared after 6 days. Swelling lasted an average of 3.6 days and disappeared after 8 days. Tolerance was excellent. Two patients (4.3%) displayed diarrhoea and nausea and one (2.2%) pruritus. These side-effects did not necessitate the suspension of treatment. It is felt that phosphomycin may be regarded as a drug of choice in the treatment of odontostomatological infection of bacterial origin.
