More than 80% of multiple sclerosis (MS) patients suffer from fatigue. Despite this, there are few therapeutic options and evidence-based pharmacological treatments are lacking. The associated societal burden is substantial (MS fatigue is a major reason for part-time employment or early retirement), and at least one out of four MS patients view fatigue as the most burdensome symptom of their disease. The mechanisms underlying MS-related fatigue are poorly understood, and objective criteria for distinguishing and evaluating levels of fatigue and tiredness have not yet been developed...

Neonatal pneumonia is reported to be the primary cause of neonatal respiratory failure and one of the common causes of neonatal hospitalization and death in developing countries. Chest X-ray was considered the gold standard for diagnosis of neonatal pneumonia. Lung ultrasonography has been described as a valuable noninvasive tool for the diagnosis of many neonatal pulmonary diseases. We report a case of ventilation associated neonatal pneumonia with very early diagnosis using lung ultrasound before any significant radiographic changes in chest X-ray or laboratory findings suggestive of infection...

We report on the case of a young infant with chronic diarrhea that worsened and turned into hypovolemic shock with methemoglobinemia. We underline and discuss the main features of food protein-induced enterocolitis syndrome (FPIES). FPIES is a non-IgE-mediated food allergy involving tumor necrosis factor-alpha (TNF-α). Many triggering foods exist but cow's milk, as in the case reported herein, is one of the most frequent. It can start early or be delayed and start around the average age of 5 months. Symptoms are nonspecific with diarrhea and vomiting, but in the presence of methemoglobinemia, the diagnosis must be seriously considered...

BACKGROUND: The microvascular free fibula flap has become the gold standard for reconstruction of complex mandibular defects since its description by Hidalgo in 1989. Prior studies have demonstrated its safety and efficacy in the pediatric population. However, this reconstructive method is often used only as a last resort for correction of congenital mandibular hypoplasia, after failure of bone grafting and distraction osteogenesis. The authors describe our experience using this technique, facilitated by virtual planning and prefabricated cutting jigs, for children with severe congenital mandibular hypoplasia...
