Etiology and antimicrobial resistance patterns in early and late neonatal sepsis in a Neonatal Intensive Care Unit.

Introduction: Neonatal sepsis is one of the main causes of death among newborn infants. Empirical antimicrobial treatment is based on epidemiological information and antimicrobial susceptibility tests. The objective of this study was to describe etiologic agents and their antimicrobial susceptibility among newborn infants with early-onset neonatal sepsis (EONS) or late-onset neonatal sepsis (LONS) at a Neonatal Intensive Care Unit.

Rhinovirus is an important pathogen in upper and lower respiratory tract infections in Mexican children.

Background: Most of the studies characterizing the incidence of rhinovirus (RV) have been carried out in hospitalized children and in developed countries. In those studies, RV-C has been associated with more severe respiratory tract infections than RV species A and B. In this study we determined the frequency and diversity of RV strains associated with upper and lower respiratory tract infections (URTI, LRTI) in Mexico, and describe the clinical characteristics of the illness associated with different RV species.

Pediatric donor cell leukemia after allogeneic hematopoietic stem cell transplantation in AML patient from related donor.

Here we present a male patient with acute myeloid leukemia (AML) initially diagnosed as M5 and with karyotype 46,XY. After induction therapy, he underwent a HLA-matched allogeneic hematopoietic stem cell transplantation, and six years later he relapsed as AML M1 with an abnormal karyotype //47,XX,+10[2]/47,XX,+11[3]/48,XX,+10,+11[2]/46,XX[13]. Based on this, we tested the possibility of donor cell origin by FISH and molecular STR analysis.

Is there still room for novel viral pathogens in pediatric respiratory tract infections?

Viruses are the most frequent cause of respiratory disease in children. However, despite the advanced diagnostic methods currently in use, in 20 to 50% of respiratory samples a specific pathogen cannot be detected. In this work, we used a metagenomic approach and deep sequencing to examine respiratory samples from children with lower and upper respiratory tract infections that had been previously found negative for 6 bacteria and 15 respiratory viruses by PCR.

Update of the Mexican College of Rheumatology guidelines for the pharmacologic treatment of rheumatoid arthritis.

Background: The pharmacologic management of rheumatoid arthritis has progressed substantially over the past years. It is therefore desirable that existing information be periodically updated. There are several published international guidelines for the treatment of rheumatoid arthritis that hardly adapt to the Mexican health system because of its limited healthcare resources.

Introduction: Mortality rates in preterm births and stillbirth are high.

Objective: To identify maternal risk factors relating to stillbirth in preterm infants.

Material And Methods: We conducted a cross-sectional, analytic study of 1,022 newborns between 20 and 36 weeks of gestation, from September 2004 to August 2005.

[Modified Misgav-Labach at a tertiary hospital].

Background: According to several studies from around the globe, the modified Misgav Ladach technique simplifies the surgical procedure for cesarean section, reduces operation time, costs, and complications, and optimizes obstetric and perinatal outcomes.

Objective: Compare obstetric outcomes between patients operated on using traditional cesarean section technique and those operated on using modified Misgav Ladach technique.

Patients And Methods: The study included 49 patients operated on using traditional cesarean section technique and 47 patients operated on using modified Misgav Ladach technique to compare the outcomes in both surgical techniques.

New ocular findings in two sisters with Yunis-Varón syndrome and literature review.

The Yunis-Varón syndrome (YVS) represents a rare autosomal recessive syndrome of easy recognition characterized by cleidocraneal dysplasia, absence of thumbs and halluces, distal aphalangia, ectodermal anomalies, and poor outcome. Here, we report two sisters with YVS who also had papillo-macular atrophic chorioretinopathy with "salt-and-pepper" appearance that could not be attributed to environmental or metabolic causes. Our best hypothesis is that the ocular findings in our two patients are part of the phenotypic manifestations of YVS.

Holoprosencephaly and genitourinary anomalies in fetal methotrexate syndrome.

Prenatal exposure to methotrexate (MTX) in the first trimester may lead to fetal death, and surviving children have increased risks for cranial dysostosis, dysmorphic facies, skeletal malformations, limb defects, growth retardation, and, in some cases, developmental delay, a pattern of defects recognized as fetal MTX syndrome (FMS). We report on a male infant who, in addition to severe FMS, showed previously undescribed central nervous system (CNS) and genitourinary anomalies that contributed to the further delineation. The propositus was born to a G2, 20-year-old mother with an irregular menstrual history.

Management of infectious complications in percutaneous nephrolithotomy.

Infectious complications are one of the most frequent and feared adverse medical events in percutaneous nephrolithotomy. They represent a dangerous and life-threatening condition, especially when postoperative septicemia or severe sepsis develops. In order to limit morbidity and mortality it is crucial to recognize preoperative and intraoperative risk factors that could be clear contributors to an adverse infectious event; those factors are mainly immunosuppression caused by some comorbidities, presence of urinary infection or colonization, stone characteristics, obstruction, long-lasting operation, and high intrapelvic pressure during nephrolithotomy.

[Teenage pregnancy as a risk factor for fetal abuse].

Objective: To identify if pregnancy in adolescence is a risk factor for fetal abuse.
