Introduction: Invasive disease as a result Campylobacter spp. is rarely reported. Bloodstream infections have been reported in patients with immune deficiency or other serious underlying conditions. We conducted a prospective study to know the incidence of Campylobacter jejuni bacteremia in pediatric patients and its susceptibility to erythromycin and ciprofloxacin.
Methods: The identification of Campylobacter isolates was based on routine culture methods. Antimicrobial susceptibility was performed using a disk diffusion method.
Results: During April 2010-June 2012, at Hospital Niño Jesús of Madrid, Campylobacter spp. was isolated from 171 stool specimens in 154 patients. The median age was 2 years (3 months-21 year). One hundred and one (66%) isolates were identified as C. jejuni. Nine patients with enteritis due C. jejuni (9%) were immunocompromised. Erythromycin resistance was observed in 5% of the isolates. The resistance to ciprofloxacin was 88%. Blood cultures were obtained of 19 patients infected with C. jejuni (19%). Of these, one had C. jejuni bacteremia. During the study period, other episode of C. jejuni bacteremia was detected in one patient different without positive stool culture for C. jejuni (0.34% of all bloodstreams infections). Both patients were immunocompromised.
Conclusions: Campylobacter spp. is an uncommon cause of bloodstream infection in our serie occurring in pediatric patients with immune deficiency as predisposing factor. In our institution, empirical use of fluoroquinolones for Campylobacter infections should not be recommended by the high rate of resistance. Moreover in our study the resistance to erythromycin is low, however is advisable its surveillance.

Objective: Authors characterized all published adult cases of cutaneous, intertriginous Langerhans cell histiocytosis (LCH) to bring this clinical presentation to the attention of clinicians. We emphasize the morphology, histopathology, immunohistochemical profiles, and genetic mutations associated with these cases.
Materials And Methods: A systematic review of the National Center for Biotechnology Information's PubMed was conducted, utilizing the following specific key words to identify all adult LCH patients with cutaneous intertriginous involvement: "Intertriginous Langerhans," "Vulvar Langerhans," "Genital Langerhans," "Perineal Langerhans," "Perianal Langerhans," "Intergluteal Langerhans," "Inguinal Langerhans," "Axillary Langerhans," and "Inframammary Langerhans.

Background: The best multimodal approach for resectable locally advanced esophageal adenocarcinoma is unclear. An important question is whether perioperative chemotherapy is preferable to preoperative chemoradiotherapy.
Methods: In this phase 3, multicenter, randomized trial, we assigned in a 1:1 ratio patients with resectable esophageal adenocarcinoma to receive perioperative chemotherapy with FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) plus surgery or preoperative chemoradiotherapy (radiotherapy at a dose of 41.

The main objective of this prospective, multicenter study (REVEAL-CP) was to test children with cerebral palsy-like signs and symptoms for raised 3--methyldopa (3-OMD) blood levels, a biomarker for aromatic L-amino acid decarboxylase deficiency (AADCd). A secondary objective was to characterize the molecular basis for the defective aromatic L-amino acid decarboxylase (AADC) gene product. Patients were identified in pediatric secondary and tertiary care hospitals through database searches and personal communication.
