    Full Text Available El estafilococo coagulasa negativa es actualmente un importante patógeno nosocomial y agente causal de infección en el neonato. Cepas multirresistentes comúnmente aisladas de recién nacidos sometidos a cuidados intensivos dificultan la terapéutica, por lo que se hace necesario el empleo de combinaciones antibióticas que garanticen un efecto antibacteriano más eficiente. Se presentan los resultados obtenidos en un paciente con bronconeumonía adquirida por Staphylococcus haemolyticus multirresistente y que fue sometido a tratamiento combinado de azlocillin y amikacina. Se estudió el patrón de resistencia de la cepa para 30 antibióticos por métodos de difusión y dilución, así como la efectividad in vitro de la combinación antibiótica aplicada por el método del «tablero de ajedrez». Se observó en los resultados in vitro una marcada potencialización de la actividad aminoglucosídica por la presencia del antibiótico beta-lactámico, resultado que se correspondió con una excelente respuesta in vivo.Negative-coagulase Staphyloccocus, is at present time an important nosocomial pathogen and a causal agent of neonatal infection. Multirresistant strains commonly isolated from newborn under intensive care, make difficult treatment, so it is necessary use of antibiotic combination to assure a more efficient antibacterial effect. We present results obtained in a patient presenting with acquired bronchopneumonia from multirresistant Staphylococcus haemolyticus who received a combination of Azlocillin and Amikacin. Resistance pattern to this strain was studied by diffusion and dilution methods, as well as in vitro effectiveness of antibiotic combination, applied by "Chequerboard" method. In in vitro results, we found a significant potentiation of aminoglucoside activity by presence of Beta-lactamic antibiotic, result corresponding to an in vivo excellent response.

    Introduction: Neonatal mastitis is an inflammatory condition of the breast frequently associated with Staphylococcus aureus. While Panton–Valentine leucocidin (PVL), a B‐pore‐forming cytotoxin, is commonly associated with enhanced virulence in community‐acquired methicillin‐resistant S. aureus isolates, this is the first report to our knowledge of neonatal mastitis caused by PVL‐positive S. aureus.\\r\

    Neonatal sepsis causes 1.4 million (36%) neonatal deaths annually. Staphylococcus aureus (SA), a common skin pathogen, remains the second leading cause of late-onset sepsis in the neonatal intensive care unit (NICU). Methicillin-resistant Staphylococcus aureus (MRSA), a resistant strain of SA, has created a significant global communicable health risk, especially in the NICU. To examine evidence related to NICU infection control practices surrounding MRSA surveillance, identification, and isolation in response to the clinical question, "What strategies should be universally implemented in the NICU to identify and prevent the spread of MRSA?" Databases were examined for articles on the topical area of MRSA in the neonate. Key terms were used to streamline the search, resulting in 20 primary works and 3 guideline/consensus statements considered imperative in response to the clinical questions. Hand hygiene remains the cornerstone to sound infection control practice. Colonization often leads to systemic infection, with smaller neonates at greatest risk. Hospital infection control compliance has improved outcomes. MRSA surveillance has reduced horizontal spread. No universal, specific recommendations exist to guide surveillance and management of MRSA in the NICU. Standardized guidelines with procedures for hand hygiene, patient surveillance and isolation, and patient cohorting with recommended staffing patterns should guide practice in the NICU. Both MRSA culture and polymerase chain reaction effectively identify positive patients. Decolonization practices are not yet clear. Evaluation of standard isolation practices versus outbreak response and approaches to neonatal decolonization should be evaluated for efficacy, safety, and resistance.

    Full Text Available Staphylococcus aureus es el principal agente causante de mastitis bovina en Argentina y en el mundo. Esta bacteria ocasiona infecciones crónicas que generan importantes pérdidas a los productores y la industria lechera. El objetivo de este artículo es caracterizar los mecanismos que intervienen en la infección causada por S. aureus en la glándula mamaria bovina, evaluando dos aspectos diferentes del proceso infeccioso: por un lado, lo vinculado con la respuesta inmune innata por parte del hospedador, y por otro, la capacidad de la bacteria para evadir el sistema inmune e interactuar con diferentes tipos celulares. La exploración de la interacción de S. aureus con el sistema inmune de la glándula mamaria bovina permitirá identificar blancos para delinear nuevas alternativas preventivas o curativas, que contribuyan a evitar o eliminar las infecciones causadas por este organismo.

    The risk of nosocomial infection due to Staphylococcus aureus in fullterm newborns is higher under hospital conditions where there are overcrowded nurseries and inadequate infection control techniques. We report on an outbreak of skin infection in a Maternity Nursery (May 21, 2000) and the measures undertaken to bring the epidemic under control. These measures included: separating neonates already present in the nursery on August 23, 2000 from ones newly arriving by creating two different cohorts, one of neonates born before this date and one of neonates born later; restricting healthcare workers caring for S. aureus- infected infants from working with non-infected infants; disallowing carrier healthcare workers from caring for patients; introducing contact and droplet precautions (including the routine use of gowns, gloves, and mask); ensuring appropriate disinfection of potential sources of contamination. A representative number of isolates were typed by genomic DNA restriction length polymorphism analysis by means of pulsed-field gel electrophoresis (PFGE). Among the 227 cases of skin lesions, microbiological laboratory analyses confirmed that 175 were staphylococcal infections. The outbreak showed a gradual reduction in magnitude when the overcrowding of the Nursery was reduced by separating the newborns into the two different Nurseries (two cohorts). The genotyping of the strains by PFGE confirmed the nurse-to-newborn transmission of S. aureus. The measures adopted for controlling the S. aureus outbreak can, in retrospect, be assessed to have been very effective.

    Staphylococcus haemolyticus is a common colonizer and cause of late-onset sepsis (LOS) in preterm neonates. By describing genetic relatedness, we aimed to determine whether mother's breast milk (BM) is a source of S. haemolyticus colonizing neonatal gut and skin and/or causing LOS. S. haemolyticus was isolated from stool and skin swabs of 49 BM-fed preterm neonates admitted to neonatal intensive care unit, 20 healthy BM-fed term neonates and BM of mothers once a week and typed by multilocus variable-number tandem-repeat analysis (MLVA) and multilocus sequence typing (MLST). Virulence-related genes were determined by PCR. Compared with term neonates S. haemolyticus colonized more commonly gut (35% vs 89.9%; pskin (50% vs 91.8%; pskin with MLVA-types indistinguishable from those in BM. Most frequent MLVA-types belonged to sequence type 3 or 42, comprised 71.1-78.4% of isolates from preterm neonates/mothers and caused all seven LOS episodes. LOS-causing strain colonized the gut of 4/7 and the skin of 5/7 neonates, but not BM, prior to onset of LOS. S. haemolyticus colonizing gut and skin or causing LOS in preterm neonates rarely originate from BM, but are mecA-positive strains adapted to hospital environment.

    Background Staphylococcus aureus, particularly methicillin-resistant S. aureus (MRSA), in mothers can cause serious outcomes in neonates. We aimed to elucidate the associations of S. aureus and MRSA carriage between mothers and neonates. Methods A prospective cohort study was conducted between August and November 2015 in two hospitals in Shenzhen, China. Chinese pregnant women and their neonates who met the inclusion criteria were included in this study; samples and relevant information were collected. We assessed maternal–neonatal associations by using Poisson regression models. Results Overall, 1834 mothers and their neonates were included in this study. The prevalence of isolate carriage among the mothers was as follows: S. aureus (nasal, 25.8%; vaginal, 7.3%; and nasal and vaginal, 3.3%) and MRSA (nasal, 5.7%; vaginal, 1.7%; and nasal and vaginal, 0.5%). The incidences of S. aureus and MRSA carriage among neonates were 3.3% and 0.8%, respectively. Of the 21 maternal–neonatal pairs with S. aureus carriage, 14 were concordant pairs with the same phenotypic and molecular characteristics. After adjustment, the relative risks and 95% confidence intervals (CIs) between the S. aureus carriage of neonates and nasal S. aureus carriage, vaginal S. aureus carriage, and both nasal and vaginal S. aureus carriage of mothers were 2.8 (95% CI, 1.6–4.8), 7.1 (95% CI, 4.1–12.4), and 9.6 (95% CI, 4.2–22.4), respectively. Conclusion S. aureus carriage in mothers increases the risk for neonates. PMID:29731644

    Coagulase-negative staphylococci (CNS) are among the most prevalent microorganisms that colonize and cause sepsis in neonatal intensive care units (NICU). We had previously identified a strain of CNS, Staphylococcus haemolyticus (TOR-35), in the NICU at Mount Sinai Hospital, that had been repeatedly isolated from blood cultures from neonates. We therefore carried out a prospective study to determine the frequency and time of colonization and the frequency of bacteremia in neonates over a 3.5 month period. This was accomplished by obtaining surface swabs within 1 h of birth and on days 3, 5, and 7 and by characterizing all blood culture isolates of CNS. We also determined what percentage of neonatal CNS bacteremias were due to this strain, between January 1, 1987 and December 31, 1990, by retrieving and typing all stock cultures of CNS from that period. All isolates were typed by species identification and antimicrobial susceptibility profile code. There were 76 (38%) neonates that became colonized with the TOR-35 strain at some time during their NICU stay. Lower birth weight was associated with colonization (p TOR-35 strain during the prospective study. Of the 4 years of neonatal bacteremias that were studied retrospectively, there were 252 episodes of CNS bacteremia, of which 27 (11%) were due to the TOR-35 strain. The TOR-35 strain has become endemic in our NICU and appears to selectively colonize premature, low birth weight newborn infants, but only infrequently causes bacteremia.

    Full Text Available Abstract Background Methicillin-resistant Staphylococcus aureus is a serious cause of morbidity and mortality in hospital environment, but also, lately, in the community. This case report is, to our knowledge, the first detailed description of a community-associated methicillin-resistant S. aureus ST80 orbital cellulitis in a previously healthy neonate. Possible predisposing factors of microbial acquisition and treatment selection are also discussed. Case presentation A 28-day-old Caucasian boy was referred to our hospital with the diagnosis of right orbital cellulitis. His symptoms included right eye proptosis, periocular edema and redness. Empirical therapy of intravenous daptomycin, rifampin and ceftriaxone was initiated. The culture of pus yielded a methicillin-resistant S. aureus isolate and the molecular analysis revealed that it was a Panton-Valentine leukocidine-positive ST80 strain. The combination antimicrobial therapy was continued for 42days and the infection was successfully controlled. Conclusions Clinicians should be aware that young infants, even without any predisposing condition, are susceptible to orbital cellulitis caused by community-associated methicillin-resistant S. aureus. Prompt initiation of the appropriate empirical therapy, according to the local epidemiology, should successfully address the infection, preventing ocular and systemic complications.

    Full Text Available One of the significant risk factor in the development of nosocomial Staphylococcal infections is bacteria Staphylococcus aureus (S. aureuscolonized in the nose of health personnel. The meticilin resistant S. aureus (MRSA was detected in the repeated blood cultures of two babies who had been followed for about 20 days in neonatal intensive care due to premature birth. Because of the failure to find the source in the assesment of the infants of whom MRSA reproduction continue, despite the appropriate treatment according to the results of antibiograms, examinations were performed fort he environment and the healtyh personnel. Cultures were taken from the total parenteral nutrition (TPN solution given to the babies. S. aureus growth was detected in the received culture. Therefore cultures were obtained from the places where there will be source in the division where TPN was prepared and nsal cultures were taken from the personnel. Because of growth of S. aureus only in the nasal cultures of the personnel, considering that the source was the personnel, the personnel were given the treatment of mupirocin pomad for five days, and during this period the work of the staff were replaced. There was not any growth in the TPN received at the and of the treatment an in the blood cultures of the patients. These facts showed us the necessity of making the necessary screening by considering the health personnel can also be the source in case of any S. aureus growth.

También se comparó la actividad terapéutica de los fagos frente a vancomicina y clindamicina. Resultados. El cóctel de fagos y la terapia a diversas dosis fueron efectivos para prevenir y controlar infecciones localizadas por MRSA, su actividad fue similar a la de vancomicina y clindamicina. La dosis única del cóctel de fagos no logró controlar la infección localizada; asimismo, la fagoterapia no resultó efectiva en infecciones sistémicas. Conclusiones. La fagoterapia se proyecta como una alternativa viable frente a infecciones causadas por MRSA. Se requieren estudios que evalúen aspectos relacionados con la inocuidad de los fagos frente al paciente

  1. Mastite bovina causada por Staphylococcus spp. resistentes à meticilina: revisão de literatura

    Directory of Open Access Journals (Sweden)

    José Givanildo Silva

    Full Text Available RESUMO: Staphylococcus spp. são os micro-organismos mais relacionados a casos de mastite bovina. Algumas cepas destes micro-organismos têm apresentado fatores de virulência como genes de resistência a antimicrobianos com destaque para a resistência à meticilina que é um problema de saúde pública. Esta revisão de literatura tem o objetivo de compilar dados sobre a mastite bovina causada por Staphylococcus spp. resistente à meticilina (MRS. Apesar desse antimicrobiano não ser comumente utilizado no tratamento das mastites, a frequência de casos de infecção da glândula mamária causada por MRS tem variado entre 1,34 a 47,6%. Acredita-se que o contato dos humanos com animais positivos para MRS e vice-versa favoreça a transmissão deste patógeno entre as espécies, contribuindo para a variação nas taxas de infecção. A detecção de MRS pode ser realizada por meio de provas fenotípicas, moleculares ou sorológicas e as medidas de controle devem contemplar a identificação dos casos, segregação dos animais, estudo epidemiológico da fonte de infecção do rebanho, além da constante limpeza e higienização do ambiente de confinamento, equipamentos e utensílios de ordenha. Casos de mastite ocasionados por esse patógeno assumem relevância para a saúde pública, pois a ingestão de leite e/ou derivados contaminados podem desencadear a transferência de MRS para seres humanos. Com isso, é necessário um alerta constante quanto à vigilância epidemiológica em fazendas leiteiras.

    Full Text Available Despite infection prevention efforts, neonatal intensive care unit (NICU patients remain at risk of Methicillin-resistant Staphylococcus aureus (MRSA infection. Modes of transmission for healthcare-associated (HA and community-associated (CA MRSA remain poorly understood and may vary by genotype, hindering the development of effective prevention and control strategies. From 2008-2010, all patients admitted to a level III NICU were screened for MRSA colonization, and all available isolates were spa-typed. Spa-type t008, the most prevalent CA- genotype in the United States, spa-type t045, a HA- related genotype, and a convenience sample of strains isolated from 2003-2011, underwent whole-genome sequencing and phylodynamic analysis. Patient risk factors were compared between colonized and noncolonized infants, and virulence and resistance genes compared between spa-type t008 and non-t008 strains. Epidemiological and genomic data were used to estimate MRSA importations and acquisitions through transmission reconstruction. MRSA colonization was identified in 9.1% (177/1940 of hospitalized infants and associated with low gestational age and birth weight. Among colonized infants, low gestational age was more common among those colonized with t008 strains. Our data suggest that approximately 70% of colonizations were the result of transmission events within the NICU, with the remainder likely to reflect importations of "outside" strains. While risk of transmission within the NICU was not affected by spa-type, patterns of acquisition and importation differed between t008 and t045 strains. Phylodynamic analysis showed the effective population size of spa-type t008 has been exponentially increasing in both community and hospital, with spa-type t008 strains possessed virulence genes not found among t045 strains; t045 strains, in contrast, appeared to be of more recent origin, with a possible hospital source. Our data highlight the importance of both intra

    Full Text Available Jerked beef - JB - é um produto cárneo curado, salgado e seco ao sol, derivado de um típico produto cárneo brasileiro - o charque. Ambos carecem de estudos que orientem seu aprimoramento. Staphylococcus spp. têm sido reportado como o gênero predominante na microbiota do produto, o que evidencia o risco de desenvolvimento de linhagens enterotoxigênicas de S. aureus. Foram empregadas duas linhagens inócuas de estafilococos na elaboração de JB, a fim de avaliar sua influência sobre o desenvolvimento de S. aureus por mecanismo competitivo ou pela produção de bacteriocinas. Os resultados demonstraram que ambas inibiram o desenvolvimento do patógeno tanto in vitro como durante o processamento do produto. Não se observou produção de compostos inibitórios pelas linhagens iniciadoras, ficando a explicação para a inibição observada restrita ao mecanismo competitivo. Este trabalho permitiu demonstrar a possibilidade de aumentar a segurança e padronização de JB pelo emprego de culturas bacterianas selecionadas.Jerked beef - JB - is a sun-dried, salted and cured meat product, derived from charqui.

The presence of this genus reveals a possible hazard for S. aureus growth. Two staphilococci strains commonly used as starter in fermented meat products have been employed with the purpose to inhibiting S. aureus either through competitive action or through the production of bacteriocins. The results demonstrated the inhibition S. aureus growth, probably through a competitive action, as they grow better in the medium. These starters have not produced any inhibitory compound. These informations led us to conclude that it is possible to improve the safety and quality standardization of JB through appropriate starter cultures.

    To characterize the epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) transmission and infections in a level IIIC neonatal intensive care unit (NICU) and identify barriers to MRSA control. Retrospective cohort study in a university-affiliated NICU with an MRSA control program including weekly nares cultures of all neonates and admission nares cultures for neonates transferred from other hospitals or admitted from home. Medical records were reviewed to identify neonates with NICU-acquired MRSA colonization or infection between April 2007 and December 2011. Compliance with hand hygiene and an MRSA decolonization protocol were monitored. Relatedness of MRSA strains were assessed using pulsed-field gel electrophoresis (PFGE). Of 3,536 neonates, 74 (2.0%) had a culture grow MRSA, including 62 neonates with NICU-acquired MRSA. Nineteen of 74 neonates (26%) had an MRSA infection, including 8 who became infected before they were identified as MRSA colonized, and 11 of 66 colonized neonates (17%) developed a subsequent infection. Of the 37 neonates that underwent decolonization, 6 (16%) developed a subsequent infection, and 7 of 14 (50%) that remained in the NICU for 21 days or more became recolonized with MRSA. Using PFGE, there were 14 different strain types identified, with USA300 being the most common (31%). Current strategies to prevent infections-including active identification and decolonization of MRSA-colonized neonates-are inadequate because infants develop infections before being identified as colonized or after attempted decolonization. Future prevention efforts would benefit from improving detection of MRSA colonization, optimizing decolonization regimens, and identifying and interrupting reservoirs of transmission.

    The early detection of a methicillin-resistant Staphylococcus aureus (MRSA) outbreak is decisive to control its spread and rapidly initiate adequate infection control measures. Therefore, prompt determination of epidemiologic relatedness of clinical MRSA isolates is essential. Genetic typing methods have a high discriminatory power but their availability remains restricted. In this study, we aimed to challenge matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) as a typing tool of a nosocomial MRSA outbreak in a neonatal intensive care unit. Over a 2-year period, 15 MRSA isolates were recovered from patients (n = 14) and health care workers (n = 1) at the neonatal intensive care unit. Five reference strains were included for comparison. Identification was performed by MALDI-TOF MS and susceptibility profiles determined by automated broth microdilution. Typing analysis by MALDI-TOF MS included mean spectrum profiles and subsequent dendrogram creation using BioNumerics software. Results were compared with spa typing and pulsed-field gel electrophoresis (PFGE). Our study showed good concordance (93%) between PFGE, spa typing, and MALDI-TOF MS for the outbreak-related MRSA strains. MALDI-TOF MS typing showed excellent typeability and discriminatory power but showed poor reproducibility. This study is one of the first to document the potential usefulness of MALDI-TOF MS with standardized data analysis as a typing tool for investigating a nosocomial MRSA outbreak. A concordance of 93% compared to reference typing techniques was observed. However, because of poor reproducibility, long-term follow-up of prospective isolated strains is not practical for routine use. Further studies are needed to confirm our observations.

    Full Text Available Objective: To determine, by phenotypic and genotypic methods, oxacillin susceptibility in Staphylococcus aureus strains isolated from pediatric and neonatal intensive care unit patients seen at the University Hospital of the Botucatu School of Medicine.Methods: A total of 100 S. aureus strains isolated from the following materials were studied: 25 blood cultures, 21 secretions, 12 catheters, 3 cannulae and one chest drain from 62 patients in the neonatal unit, and 36 blood cultures, one pleural fluid sample and one peritoneal fluid sample from 38 patients in the pediatric unit. Resistance of the S. aureus isolates to oxacillin was evaluated by the disk diffusion method with oxacillin (1 μg and cefoxitin (30 μg, agar screening test using Mueller-Hinton agar supplemented with 6 μg/ml oxacillin and 4% NaCl, and detection of the mecA gene by PCR. In addition, the isolates were tested for β-lactamase production using disks impregnated with Nitrocefin and hyperproduction of β-lactamase using amoxicillin (20 μg and clavulanic acid (10 μg disks.Results: Among the 100 S. aureus strains included in the study, 18.0% were resistant to oxacillin, with 16.1% MRSA being detected in the neonatal unit and 21.0% in the pediatric unit. The oxacillin (1 μg and cefoxitin (30 μg disk diffusion methods presented 94.4% and 100% sensitivity, respectively, and 98.8% specificity. The screening test showed 100% sensitivity and 98.8% specificity. All isolates produced β-lactamase and one of these strains was considered to be a hyperproducer.Conclusions: The 30 μg cefoxitin disk diffusion method presented the best result when compared to the 1 μg oxacillin disk. The sensitivity of the agar screening test was similar to that of the cefoxitin disk diffusion method and higher than that of the oxacillin disk diffusion method. We observed variations in the percentage of oxacillin-resistant isolates during the study period, with a decline over the last years which

    Full Text Available BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA is among the most important nosocomial pathogens in the intensive care unit (ICU worldwide, including Taiwan. Since 1997, our neonatal ICUs (NICUs had become endemic for MRSA. METHODOLOGY/PRINCIPAL FINDINGS: To control MRSA spread in our NICUs, we implemented a series of infection control measures stepwise, including reinforcement of hand hygiene since January 2000, augmentation of aseptic care over the insertion site of central venous catheter since July 2001, introduction of alcohol-based handrubs since April 2003, surveillance culture for MRSA and cohort care for the colonized patients between March 2003 and February 2004, and surveillance culture with subsequent decolonization of MRSA between August 2005 and July 2006. After implementation of these measures, MRSA healthcare-associated infection (HAI density reduced by 92%, from 5.47 episodes per 1000 patient-days in 1999 to 0.45 episodes per 1000 patient-days in 2006; MRSA bloodstream infection reduced from 40 cases in 1999 to only one case in 2006. Compared to those obtained during the period of surveillance culture without decolonization, both rates of MRSA colonization (8.6% vs. 41%, p<0.001 and infection (1.1% vs. 12%, p<0.001 decreased significantly during the period of surveillance and decolonization. Molecular analysis of the clinical isolates during the study period showed that the endemic clone, which dominated between 1998 and 2005, almost disappeared in 2006, while the community clones increased significantly in 2006-2007. CONCLUSION/SIGNIFICANCE: Through infection control measures, MRSA HAIs can be successfully controlled, even in areas with high levels of endemic MRSA infections such as our NICUs.

    Conclusions: Modification of the empiric treatment regimen for neonatal late‐onset sepsis with use of oxacillin showed a significant reduction in S. aureus infections, as well as a reduction in the frequency of infections with major organ system involvement and mortality due to infection with this microorganism. As a result, oxacillin can be considered as an effective treatment for late‐onset sepsis, making it possible to avoid broad‐spectrum antibiotics.

    Evaluate the effects of neonatal malnutrition on the microbicidal response and viability of in vitro macrophages infected with Staphylococcus aureus sensitive/resistant to methicillin. Male Wistar rats (n = 24) were divided into two distinct groups: nourished (rats breast-fed by mothers undergoing diet with 17% casein) and malnourished (rats breast-fed by mothers undergoing diet with 8% casein). Macrophages were recovered after surgical tracheostomy procedure by collecting bronchoalveolar lavage. Four systems were established: negative control, composed only by phagocytes; positive control, macrophages plus lipopolysaccharide; and two test systems, macrophages plus Staphylococcus aureus sensitive and resistant to methicillin. Plates were incubated at 37 °C for 24 h. After this period, tests for the analysis of cell viability and microbicidal response were performed. In the statistical analysis, the Student's t and ANOVA tests were used, accepting p resistant Staphylococcus aureus. However, increased production of superoxide anion in the malnourished group was detected. Neonatal malnutrition focusing on critical periods of development promoted lower expression of iNOS, nitric oxide production, cell viability, and exacerbated reactive oxygen species production. The high levels of reactive oxygen species may favor the onset of serious and systemic infections with fatal outcome if associated with methicillin-resistant Staphylococcus aureus.

Raw and pasteurized milk, hand and forearms of cheese makers, brine, hoops flushing water and cheeses were analyzed for SC+ and S. aureus. High counts of SC+ and S. aureus (4x10³ to 4.8x10(6 CFU/ml and 4x10³ to 3.3x10(5 CFU/ml, respectively were found in raw milk in four evaluations, but they decreased to values lower than 1 CFU/ml after pasteurization. In three evaluations, counts of SC+ in prato cheese samples were above legal limits (10(4, 10(5 and 2.3x10(5 CFU/g. The hoops flushing water and brine were not important contamination sources, both with counts lower than 1CFU/ml. The cheese makers probably were the main source of contamination, since high counts in cheese were correlated to high counts in their hands (4x10² CFU/cm² or forearms (4.7x10² and 3.3x10³ CFU/cm².

    Full Text Available This study aimed to detect methicillin resistant and slime producing Staphylococcus aureus in cases of bovine mastitis. A triplex PCR was optimized targetting 16S rRNA, nuc and mecA genes for detection of Staphylococcus species, S. aureus and methicillin resistance, respectively. Furthermore, for detection of slime producing strains, a PCR assay targetting icaA and icaD genes was performed. In this study, 59 strains were detected as S. aureus by both conventional tests and PCR, and 13 of them were found to be methicillin resistant and 4 (30.7% were positive for mecA gene. Although 22 of 59 (37.2% S. aureus isolates were slime-producing in Congo Red Agar, in PCR analysis only 15 were positive for both icaA and icaD genes. Sixteen and 38 out of 59 strains were positive for icaA and icaD gene, respectively. Only 2 of 59 strains were positive for both methicillin resistance and slime producing, phenotypically, suggesting lack of correlation between methicillin resistance and slime production in these isolates. In conclusion, the optimized triplex PCR in this study was useful for rapid and reliable detection of methicillin resistant S. aureus. Furthermore, only PCR targetting icaA and icaD may not sufficient to detect slime production and further studies targetting other ica genes should be conducted for accurate evaluation of slime production characters of S. aureus strains.Este estudo objetivou a detecção de Staphylococcus aureus resistente a meticilina e produtor do fator slime em casos de mastite bovina.

    Full Text Available BACKGROUND: Cerebral abscesses are extremely rare in neonates. Serratia marcescens is an unusual cause of sepsis and neurological spread is especially ominous. PURPOSE: To report the case of a 34-week neonate who developed this rare condition and to discuss diagnostic and therapeutic measures. CASE REPRT: A 34-week male neonate sequentially developed respiratory distress syndrome, early sepsis and necrotizing enterocolitis; later cultures revealed S. marcescens. After deterioration, a cerebral abscess became evident, which revealed S. marcescens. Clinical improvement ensued after high-dose amikacin and meropenem. CONCLUSION: Clinical signs are often non-specific. Proper diagnostic measures, neurosurgical consultation and aggressive antibiotic therapy are essential for these high-risk neonates.INTRODUÇÃO: Abscessos cerebrais são extremamente raros em neonatos.

Con el objetivo de actualizar los temas relacionados con la problemática mundial de la infección neonatal por especies de Candida, los criterios diagnósticos y el manejo terapéutico, se realizó una revisión dirigida fundamentalmente a especialistas en neonatología. Se constató que las especies que más se aíslan en los neonatos son las Candida albicans, C. glabrata, C. parapsilosis y C. tropicalis. El cuadro clínico es inespecífico y suele presentarse entre la segunda y tercera semanas de la vida. Los hallazgos de laboratorio clínico son también equívocos. El diagnóstico de certeza se establece por el aislamiento del hongo en sitios estériles como la sangre, el líquido cefalorraquídeo, el fluido pericárdico o mediante biopsia de tejido. El tratamiento curativo de primera línea contra la candidiasis invasiva en los neonatos continúa siendo el anfotericin B. En estos pacientes es de suma importancia retirar los catéteres vasculares profundos ante sospechas y en el momento de la confirmación de la infección.In Cuba, with the rise of the survival of newborn infants with a birth weight under 1500 g, the isolations of Candida species in the neonatal intensive care units may be increasingly frequent.

O grupo irradiado apresentou prejuízo nas primeiras sessões de treino quando comparado ao grupo controle; porém, seu desempenho se igualou ao dos animais controles nas últimas sessões, replicando resultados anteriores. Os resultados são discutidos no contexto da teoria do mapa espacial cognitivo.Costa, Bueno e Xavier (2005 showed that rats with hippocampus dentate gyrus lesions produced by colchicine have post-surgical tests deficits in spatial tasks involving conditional discrimination (non-matching-to-place, NMTP, although repetitive training does promote the recovery of the lamed subject's performance. The purpose of this experiment was to assess the performance of rats with selective lesions of dentate gyrus induced by neonatal ionizing radiation in the NMTP task. The irradiated group showed deficits in the first training sessions when compared to the control group. Nevertheless, the performance of lesion and control groups was similar at the end of the sessions, as previously reported. The results are discussed in light of the cognitive map theory.

    Full Text Available Cepas de Staphylococcus aureus de origem bovina foram submetidas ao tratamento com quatro fluoquinolonas na concentração subinibitória (1/2 x CMI, para avaliar a influência desses agentes sobre plasmídios. A ciprofloxacina mostrou ser a fluorquinolona mais eficiente, eliminando marcas de resistência para estreptomicina, tetraciclina, penicilina e cádmio. A norfloxacina e a pefloxacina eliminaram resistência para penicilina e tetraciclina, respectivamente; no entanto, não foi evidenciada a eliminação de plasmídio com ofloxacina. Os resultados confirmam a eficácia das fluor-quinolonas em eliminar plasmídios de resistência mostrando a importância desses estudos como contribuição para o entendimento da prevenção de linhagens multiresistentes, uma vez que as quinolonas em concentrações subinibitórias podem aumentar a sensibilidade das linhagens a outros agentes antimicrobianos.Bovine strains of Staphylococcus aureus were submitted to treatment with four fluoro-quinolones in subinhibitory concentrations (1/2 x MICs to evaluate their influence on the curing of plasmids. Ciprofloxacin showed to be the most efficient by eliminating resistance to streptomycin, tetracyclin, penicillin, and cadmium nitrate. Norfloxacin and pefloxacin eliminated penicillin- and tetracyclin-resistance respectively. Otherwise, plasmids elimination by ofloxacin was not evidenced. The results obtained in this study confirm the potential of fluoroquinolones to eliminate antibiotic-resistant plasmids, and showed to be a valuable contribution for the prevention of multi-resistant strains, and may even enhance their sensitivity to other chemotherapeutic agents.

    Most cases of necrotizing enterocolitis (NEC) are sporadic, but outbreaks in hospital settings suggest an infectious cause. Our neonatal intensive care unit (NICU) experienced an outbreak of methicillin-sensitive Staphylococcus aureus (MSSA). We aimed to assess whether the enhancement of infection prevention and control measures would be associated with a reduction in the number of cases of NEC. Retrospective chart review. A 24-bed, university-affiliated, inborn level 3 NICU. Infants of less than 30 weeks gestation or birth weight ≤ 1,500 g admitted to the NICU between January 2007 and December 2008 were considered at risk of NEC. All cases of NEC were reviewed. Infection prevention and control measures, including hand hygiene education, were enhanced during the outbreak. Avoidance of overcapacity in the NICU was reinforced, environmental services (ES) measures were enhanced, and ES hours were increased. Two hundred eighty-two at-risk infants were admitted during the study. Their gestational age and birth weight (mean ± SD) were 28.2 ± 2.7 weeks and 1,031 ± 290 g, respectively. The proportion of NEC was 18/110 (16.4%) before the outbreak, 1/54 (1.8%) during the outbreak, and 4/118 (3.4%) after the outbreak. After adjustment for gestational age, birth weight, gender, and singleton versus multiple births, the proportion was lower in the postoutbreak period than in the preoutbreak period (P control measures to manage an MSSA outbreak.

    The staphylococci are Gram-positive cocci that divide to form clusters that look like grapes. By 16S ribosomal sequencing, they are most closely related to the Gram-positive, low G+C content Bacillus-Lactobacillus-Staphylococcus genera (Woese, 1987). There are over 30 species of staphylococci identified, and they are typically found on the skin and mucous membranes of mammals. About a dozen species are frequently carried on humans, including Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus haemolyticus, Staphylococcus capitis, Staphylococcus hominis, Staphylococcus cohnii, Staphylococcus lugdunensis, Staphylococcus schleiferi, Staphylococcus saprophyticus, Staphylococcus simulans, Staphylococcus warneri and Staphylococcus xylosus.

    Full Text Available In the last decades, coagulase-negative staphylococci (CoNS, especially Staphylococcus epidermidis have become an important cause of bloodstream infections. In addition, rates of methicillin-resistance among CoNS have increased substantially, leading to the use of glicopeptides for therapy. The objective of this study was to evaluate eleven consecutives clinically relevant cases of oxacillin-resistant CoNS bacteremia in a general hospital localized in São Paulo city, Brazil. Five different species were identified by different phenotypic methods, including S. epidermidis (5, S. haemolyticus (3, S. hominis (1, S. warneri (1 and S. cohnii subsp urealyticus (1. A variety of Pulsed Field Gel Electrophoresis profiles was observed by macrorestriction DNA analysis in S. epidermidis isolates, but two of three S. haemolyticus isolates presented the same profile. These data indicated the heterogeneity of the CoNS isolates, suggesting that horizontal dissemination of these microorganisms in the investigated hospital was not frequent. One S. epidermidis and one S. haemolyticus isolates were resistant to teicoplanin and susceptible to vancomycin. The selective pressure due to the use of teicoplanin in this hospital is relevant.Staphylococcus coagulase negativos (SCoN, especialmente Staphylococcus epidermidis tem se tornado causa importante de infecções da corrente circulatória nas últimas décadas.

    Methicillin-resistant Staphylococcus aureus (MRSA) infections cause significant morbidity and mortality in neonatal intensive care units (NICUs). We characterized the clinical and molecular epidemiology of MRSA strains colonizing NICU patients. Nasal MRSA isolates (n = 250, from 96 NICU patients) recovered through active surveillance from 2009 to 2014 were characterized with staphylococcal cassette chromosome mec (SCCmec) typing and detection of mupA (marker of high-level mupirocin resistance) and qacA/B (marker associated with chlorhexidine resistance). Factors associated with community-associated (CA-) or healthcare-associated (HA-) MRSA were evaluated. The overall prevalence of MRSA nasal colonization was 3.9%. Of 96 neonates in our retrospective cohort, 60 (63%) were colonized with CA-MRSA strains and 35 (36%) were colonized with HA-MRSA strains. Patients colonized with HA-MRSA were more likely to develop MRSA infections than patients colonized with CA-MRSA (13/35, 37% versus 8/60, 13%; p 0.007), although the interval from colonization to infection was shorter in CA-MRSA-colonized infants (median 0 days, range -1 to 4 versus HA-MRSA-colonized infants, 7 days, -1 to 43; p 0.005). Maternal peripartum antibiotics were associated with CA-MRSA colonization (adjusted odds ratio (aOR) 8.7; 95% CI 1.7-45.0); intubation and surgical procedures were associated with HA-MRSA colonization (aOR 7.8; 95% CI 1.3-47.6 and aOR 6.0; 95% CI 1.4-24.4, respectively). Mupirocin- and chlorhexidine-resistant MRSA was isolated from four and eight patients, respectively; carriage of a mupirocin-resistant strain precluded decolonization. CA-MRSA strains are prominent in the NICU and associated with distinct risk factors. Given community reservoirs for MRSA acquisition and transmission, novel infection prevention strategies are needed. Copyright © 2016 European Society of Clinical Microbiology and Infectious Diseases.

    Full Text Available INTRODUÇÃO: A deficiência de biotinidase é um erro inato do metabolismo caracterizado principalmente por ataxia, crise convulsiva retardo mental, dermatites, alopécia e susceptibilidade a infecções. É atribuída a esta deficiência enzimática a forma tardia de deficiência múltipla das carboxilases. Com o objetivo de verificar a prevalência da deficiência de biotinidase e validar o teste de triagem neonatal considerando a relação custo/benefício, elaborou-se estudo prospectivo na população de recém-nascidos no Estado do Paraná. MATERIAL E MÉTODO: Em um período de 8 meses foram triados 125.000 recém-nascidos. A amostra sangüínea foi a mesma obtida para os testes de triagem para fenilcetonúria e hipotireoidismo congênito, submetida ao teste semiquantitativo colorimétrico para atividade de biotinidase. As amostras consideradas suspeitas foram repetidas em duplicatas do mesmo cartão de papel de filtro, e as que permaneceram alteradas solicitou-se novo cartão. O teste quantitativo colorimétrico da doença foi realizado nos casos em que a segunda amostra testada em duplicata sugeriu deficiência de biotinidase. RESULTADOS: A taxa de repetição em duplicata variou de 0,9% a 0,5% do total de exames realizados por mês. A taxa de reconvocação do segundo cartão foi de 0,17%, sendo que destes 212 casos, 30% não retornaram o segundo cartão solicitado. Foram identificados 2 casos, um de deficiência total de biotinidase e outro de deficiência parcial. A prevalência da doença na população de estudo foi de 1:62.500 nascidos-vivos. A sensibilidade do teste semiquantativo colorimétrico foi calculada em 100% e a especificidade 99,88%.

    Full Text Available OBJECTIVE: To evaluate risk factors associated with methicillin-resistant Staphylococcus aureus (MRSA bacteremia emergence, its prognosis, and mortality-determining factors in critically ill patients in Colombia. METHODS: A multicenter, retrospective cohort study conducted in 2005-2008 at 16 public and private reference health care institutions in Bogotá, Colombia, that form part of a national epidemiological surveillance network and a hospital network with 4 469 beds. Methicillin-resistant emergence and mortality were analyzed using descriptive and time-to-event analysis; a multivariate Cox proportional hazard regression model was built to test the association between methicillin resistance and mortality. RESULTS: A total of 372 patients were studied: 186 with MRSA bacteremia, randomly matched with 186 with methicillin-susceptible Staphylococcus aureus (MSSA bacteremia. Previous surgery, antibiotic exposure, and hospital-acquired infections were independently associated with methicillin resistance. MRSA caused longer hospital stays among survivors (median 24 versus 18 days, P = 0.014. Mortality predictors were: patient age, creatinine level over 1.21mg/dl at ICU admission, severe sepsis, and inotropic requirement. Appropriate antimicrobial therapy and antimicrobial therapy change were independent protective factors, as was male gender. CONCLUSIONS: Methicillin resistance per se was not a mortality-independent prognostic factor. Previous conditions, such as age, baseline renal impairment, severe sepsis, and inotropy demand explained the observed mortality. Appropriate antimicrobial therapy remained a protective factor. A call to improve infection control measures in Colombia is mandatory.OBJETIVO: Evaluar los factores de riesgo asociados con la aparición de bacteriemia por Staphylococcus aureus resistente a la meticilina (MRSA, su pronóstico y los factores determinantes de la mortalidad en pacientes gravemente enfermos en Colombia.

    Full Text Available El estreptococo beta-hemolítico del grupo B (SGB es uno de los principales agentes causantes de sepsis neonatal precoz. La mortalidad de los afectados oscila entre el 6 y el 20%, y la tasa de secuela neurológica llega al 30%. En 1996 el Centro de Prevención y Control de Enfermedades de Atlanta, el Colegio Americano de Obstetras y Ginecólogos y la Academia Americana de Pediatría sugirieron en consenso que el personal de atención de salud materna-neonatal debía adoptar una estrategia para la prevención de la sepsis por este germen. Los objetivos del presente trabajo prospectivo fueron determinar el porcentaje de colonización por SGB en las pacientes gestantes asistidas del 1° de julio de 2001 al 31 de diciembre de 2002 e implementar un programa de prevención de sepsis neonatal precoz por SGB a través de profilaxis antibiótica intraparto basado en cultivos. Sobre 1756 pacientes, se realizaron cultivos con hisopado vaginal y anal a 1228 (69.9%. El porcentaje de colonización materna por SGB fue del 1.4% (17 pacientes. Se presentó un caso de sepsis neonatal compatible con SGB (0.6‰ en una madre con cultivo negativo. Sólo una paciente portadora de SGB presentó factores de riesgo. Los resultados nos sugieren continuar con la estrategia de prevención basada en cultivos debido a que la mayoría de las pacientes colonizadas no presentaron factores de riesgo. Son necesarios estudios de relación costo-beneficio en nuestro medio para definir si esta estrategia de prevención es aplicable a la realidad sanitaria argentina.Group B Streptococcus (GBS is the most frequent cause of early onset of neonatal sepsis.

The surfaces studied consisted of 10x20mm chips immersed in Petri dishes containing BHI broth inoculated with S. aureus ATCC 25923. Biofilm formation was observed after 15-day incubation, when the cells were removed using the swab technique, followed by Baird Parker agar plating. Also, the efficiency of the chemical sanitizers on the chip surfaces was tested and the non-removed cells were counted on the Baird-Parker agar. After biofilm formation and use of sanitizers, the chips were respectively observed by scanning electronic microscopy following a pre-existing protocol. The obtained results showed biofilm formation on both surfaces, with bacterial count in the order of 10(7 CFU/cm² on and 10(8 CFU/cm² on stainless steel and glass surfaces, respectively.

    The congenital hypothyroidism is the endocrine illness more frequent of the childhood, it is the one that produce the devastating effects on the growth and the development. It represent one of the few causes of mental delay that it could be prevented if it is diagnosed and treaty on time. The infants affected with congenital hypothyroidism, could be detected for the apparent presence of some physical abnormalities, which comes the first days of the birth. Unfortunately, in the moment in which the classical manifestations are made present, it is very probable that cerebral damage already exists, for what the affected children should be tried before the three months of life administering them thyroid hormones. In Mexico the incidence of the congenital hypothyroidism is of one for each 1612 births for that is very important in the area of Public Health diagnose in early form and with certainty the congenital hypothyroidism. The TSH hormone or thyrotropin is formed in the hypophysis and intervenes in the synthesis of the thyroid hormones (T3, T4) when the concentration of these is adapted, the formation of TSH is inhibited, for that upon lacking the thyroid hormones the concentration of TSH in the blood is high. For these reasons the shot metabolic state of a newborn could be determined, quantifying the TSH in blood obtained by heel stab of the neonatal, or in coming blood from the umbilical cord, after 48 hours of being born. However because the TSH is similar to other hormones and is in extremely low concentrations, it is made necessary appeal analytic techniques of very sensitive and specific laboratory like the Immunoradiometric assays (Irma) in order to could determine the levels of this hormone in the blood.

    Full Text Available This qualitative study aims to identify and analyze the meanings the health team attributes to the parents' participation in the care of premature children hospitalized at a public hospital. Data were recorded and collected through semi-structured interviews performed with 23 professionals. The results show that parents' participation in the care of these children is still in an initial stage at the hospital's neonatal unit. However, there is interest from the health team to implement it because its importance is recognized in improving the clinical stability, the growth and development process of premature children. In addition to allowing for mother-child interaction and affective bonding, it prepares the mother for the child's discharge. The presence of the mother helps the nursing team by giving maternal care to the hospitalized child. On the other hand, the parents' presence interferes in the environment of the neonatal unit. It affects the work dynamics and creates insecurity among team workers, who feel supervised. Besides, there is concern regarding hospital infection. Thus, in accordance with other studies from different countries, these meanings entail reflections on the need to base the premature care in terms of collectively building a care philosophy that restores concepts of human rights, citizenship, bonding and mother-child attachment, pediatric psychology and also expands the concept of training for a participative health education.El estudio tiene como objetivo identificar y analizar los significados atribuidos por el equipo de salud con relación a la participación de la madre/padre en el cuidado del niño prematuro hospitalizado en un hospital público.

    Full Text Available Bacteremia continues to result in significant morbidity and mortality, particularly among neonates. There is scarce data on neonatal bacteremia in among Iranian neonates. In this study, we determined neonatal bacteremia isolates and their antibiotic resistance pattern in neonatal insensitive care unit at Beasat hospital, Sanandaj, Iran. During one year, all neonates admitted to the NICU were evaluated. Staphylococcal isolates were subjected to determine the prevalence of MRS and mecA gene. A total of 355 blood cultures from suspected cases of sepsis were processed, of which 27 (7.6% were positive for bacterial growth. Of the 27 isolates, 20 (74% were Staphylococcus spp as the leading cause of bacteremia. The incidence of Gram negative bacteria was 04 (14.8%. The isolated bacteria were resistant to commonly used antibiotics. Maximum resistance among Staphylococcus spp was against Penicillin, and Ampicillin. In our study, the isolated bacteria were 7.5 % Vancomycin and Ciprofloxacin sensitive. Oxacillin disk diffusion and PCR screened 35% and 30% mec a positive Staphylococcus spp. The spectrum of neonatal bacteremia as seen in NICU at Beasat hospital confirmed the importance of pathogens such as Staphylococcus spp. Penicillin, Ampicillin and Cotrimoxazol resistance was high in theses isolates with high mecA gene carriage, probably due to antibiotic selection.

Moreover, PCR has enabled us to use residue volumes of urine samples collected by non invasive, non sterile methods, what is technically adequate as GBS is not part of the normal urine flora, thus avoiding invasive procedures such as suprapubic bladder punction or transurethral catheterization. At the same time, the use of urine instead of blood samples could help preventing newborns blood spoliation.O estreptococo do grupo B (GBS constitui a causa mais freqüente de sepse neonatal precoce. O teste de referência continua sendo o isolamento em cultura, apesar de apresentar problemas de sensibilidade. O objetivo do presente estudo foi validar uma técnica de dupla amplificação e determinar a possibilidade do uso de amostras residuais de urina colhidas por método não invasivo, não estéril, para a confirmação da sepse por GBS em recém-nascidos. As amostras foram amplificadas com primers do principal gene de superfície do GBS. A insuficiência de volume de material biológico para a realização de exames para suporte de vida, além de outros necessários à identificação do agente etiológico de infecções é muito freqüente em recém-nascidos. Mesmo assim, decidimos definir critérios bastante rigorosos para a inclusão de pacientes na casuística: os recém-nascidos deveriam apresentar sinais e sintomas compatíveis com infecção pelo GBS; deveriam ter tido ao menos uma amostra enviada para cultura, podendo ser sangue, urina ou líquor; disponibilidade de volumes residuais dessas amostras, ou de outras colhidas no dia da hospitalização, antes da introdução da antibioticoterapia, de forma a possibilitar a análise por PCR, e evolução favorável com a antibioticoterapia empírica. Em apenas um dos quatro recém-nascidos a infecção foi confirmada por cultura, enquanto nos outros três casos a infecção foi considerada presuntiva (pacientes preencheram os critérios de inclusão, mas o GBS não foi isolado.

    Full Text Available Costa, Bueno e Xavier (2005 showed that rats with hippocampus dentate gyrus lesions produced by colchicine have post-surgical tests deficits in spatial tasks involving conditional discrimination (non-matching-to-place, NMTP, although repetitive training does promote the recovery of the lamed subject's performance. The purpose of this experiment was to assess the performance of rats with selective lesions of dentate gyrus induced by neonatal ionizing radiation in the NMTP task. The irradiated group showed deficits in the first training sessions when compared to the control group. Nevertheless, the performance of lesion and control groups was similar at the end of the sessions, as previously reported. The results are discussed in light of the cognitive map theory.

    Neonatal hypertension (HT) is a frequently under reported condition and is seen uncommonly in the intensive care unit. Neonatal HT has defined arbitrarily as blood pressure more than 2 standard deviations above the base as per the age or defined as systolic BP more than 95% for infants of similar size, gestational age and postnatal age. It has been diagnosed long back but still is the least studied field in neonatology. There is still lack of universally accepted normotensive data for neonates as per gestational age, weight and post-natal age. Neonatal HT is an important morbidity that needs timely detection and appropriate management, as it can lead to devastating short-term effect on various organs and also poor long-term adverse outcomes. There is no consensus yet about the treatment guidelines and majority of treatment protocols are based on the expert opinion. Neonate with HT should be evaluated in detail starting from antenatal, perinatal, post-natal history, and drug intake by neonate and mother. This review article covers multiple aspects of neonatal hypertension like definition, normotensive data, various etiologies and methods of BP measurement, clinical features, diagnosis and management.

    Full Text Available From 7% to 10% of all retinoblastomas and from 44% to 71% of familial retinoblastomas in developed countries are diagnosed in the neonatal period, usually through pre- or post-natal screening prompted by a positive family history and sometimes serendipitously during screening for retinopathy of prematurity or other reasons. In developing countries, neonatal diagnosis of retinoblastoma has been less common. Neonatal retinoblastoma generally develops from a germline mutation of RB1, the retinoblastoma gene, even when the family history is negative and is thus usually hereditary. At least one-half of infants with neonatal retinoblastoma have unilateral tumors when the diagnosis is made, typically the International Intraocular Retinoblastoma Classification (Murphree Group B or higher, but most germline mutation carriers will progress to bilateral involvement, typically Group A in the fellow eye. Neonatal leukokoria usually leads to the diagnosis in children without a family history of retinoblastoma, and a Group C tumor or higher is typical in the more advanced involved eye. Almost all infants with neonatal retinoblastoma have at least one eye with a tumor in proximity to the foveola, but the macula of the fellow eye is frequently spared. Consequently, loss of reading vision from both eyes is exceptional. A primary ectopic intracranial neuroblastic tumor known as trilateral retinoblastoma is no more common after neonatal than other retinoblastoma. For many reasons, neonatal retinoblastoma may be a challenge to eradicate, and the early age at diagnosis and relatively small tumors do not guarantee the preservation of both eyes of every involved child. Oncology nurses can be instrumental in contributing to better outcomes by ensuring that hereditary retinoblastoma survivors receive genetic counseling, by referring families of survivors to early screening programs when they are planning for a baby, and by providing psychological and practical support

Staphylococcus sp. population varied from <1CFU mL-1, in pasteurized milk to 1.5 x 107CFU mL-1, in raw milk, whereas coagulase-positive staphylococci count ranged from <1CFU mL-1, in pasteurized milk to 5.0 x 106CFU mL-1 in raw milk. Coagulase-positive staphylococci were detected in 100% (25/25 of the raw milk samples and in 8% (2/25 of cheese samples. Twelve Staphylococcus species were identified within the selected 68 isolates, being nine negative and three positive for coagulase. Raw milk samples showed a high rate of coagulase-positive, being S. aureus the most common, whereas other product samples and equipment surfaces, pieces of furniture, utensils and manipulator gloves samples presented a high frequency of coagulase-negative and low frequency of coagulase-positive. Staphylococcal enterotoxin was detected in 20% of the raw milk samples and therefore in pasteurized milk, curd and cheese. ATP measurement permitted to assess the effectiveness of the surfaces cleaning, being considered adequate in 62.1% (36/95, "alert state" in 23.2% (22/95 and inadequate in 14.7% (14/95 of surfaces evaluated.

    Sequence type 22 (ST22) methicillin-resistant Staphylococcus aureus (MRSA) harboring staphylococcal cassette chromosome mec (SCCmec) IV (ST22-MRSA-IV) has predominated in Irish hospitals since the late 1990s. Six distinct clones of community-associated MRSA (CA-MRSA) have also been identified in Ireland. A new strain of CA-MRSA, ST772-MRSA-V, has recently emerged and become widespread in India and has spread into hospitals. In the present study, highly similar MRSA isolates were recovered from seven colonized neonates in a neonatal intensive care unit (NICU) in a maternity hospital in Ireland during 2010 and 2011, two colonized NICU staff, one of their colonized children, and a NICU environmental site. The isolates exhibited multiantibiotic resistance, spa type t657, and were assigned to ST772-MRSA-V by DNA microarray profiling. All isolates encoded resistance to macrolides [msr(A) and mpb(BM)] and aminoglycosides (aacA-aphD and aphA3) and harbored the Panton-Valentine leukocidin toxin genes (lukF-PV and lukS-PV), enterotoxin genes (sea, sec, sel, and egc), and one of the immune evasion complex genes (scn). One of the NICU staff colonized by ST772-MRSA-V was identified as the probable index case, based on recent travel to India. Seven additional hospital and CA-ST772-MRSA-V isolates recovered from skin and soft tissue infections in Ireland between 2009 and 2011 exhibiting highly similar phenotypic and genotypic characteristics to the NICU isolates were also identified. The clinical details of four of these patients revealed connections with India through ethnic background or travel. Our study indicates that hospital-acquired and CA-ST772-MRSA-V is currently emerging in Ireland and may have been imported from India on several occasions.

    1988-01-01

    We have seen 10 newborn babies who developed respiratory distress and whose chest radiographs showed a miliary nodular pattern of disease. Of these infants only 3 had blood cultures that were positive for staphylococcus aureus. Of the remaining 7, 2 had conjunctivitis from which staphylococcus aureus was cultured, 4 had negative cultures and 1 did not have a blood culture done. All patients were diagnosed as having bacterial pneumonia and appeared to respond favourably to antibiotic therapy. The pulmonary abnormalities resolved. The children were clinically well in less than 3 weeks. The author suggests that the miliary pattern is one of the radiological patterns of neonatal pneumonia possibly produced by hematogenous bacterial dissemination. (orig.)

    Neonatal suppurative parotitis is very rare. One review of the English-language literature spanning 35 years found only 32 cases. Most cases are managed conservatively with antibiotic therapy; early antibiotic treatment reduces the need for surgery. The predominant organism is Staphylococcus aureus. We report a new case of neonatal suppurative parotitis in a 3-week-old boy. The patient was diagnosed on the basis of parotid swelling, a purulent exudate from a Stensen duct, and the growth of pathogenic bacteria in culture. He responded well to 9 days of intravenous antibiotic therapy. We also discuss the microbiologic and clinical patterns of this disease.

    An otherwise healthy, full-term neonate presented at day 15 of life to the pediatric emergency with generalized papulo-pustular rash for 2 d. This was finally diagnosed as bullous impetigo caused by Staphylococcus aureus (S. aureus). The skin lesions decreased significantly after starting antibiotic therapy and drainage of blister fluid. There was no recurrence of the lesions on follow-up. This case of generalized pustular eruption due to S. aureus in a neonate is reported, as it poses a diagnostic dilemma and can have serious consequences if left untreated.

    Paediatric and particularly neonatal neurosonography still remains a mainstay of imaging the neonatal brain. It can be performed at the bedside without any need for sedation or specific monitoring. There are a number of neurologic conditions that significantly influence morbidity and mortality in neonates and infants related to the brain and the spinal cord; most of them can be addressed by ultrasonography (US). However, with the introduction of first CT and then MRI, neonatal neurosonography is increasingly considered just a basic first line technique that offers only orienting information and does not deliver much relevant information. This is partially caused by inferior US performance – either by restricted availability of modern equipment or by lack of specialized expertise in performing and reading neurosonographic scans. This essay tries to highlight the value and potential of US in the neonatal brain and briefly touching also on the spinal cord imaging. The common pathologies and their US appearance as well as typical indication and applications of neurosonography are listed. The review aims at encouraging paediatric radiologists to reorient there imaging algorithms and skills towards the potential of modern neurosonography, particularly in the view of efficacy, considering growing economic pressure, and the low invasiveness as well as the good availability of US that can easily be repeated any time at the bedside.

  3. Neonatal pain

    Walker, Suellen M

    2014-01-01

    Effective management of procedural and postoperative pain in neonates is required to minimize acute physiological and behavioral distress and may also improve acute and long-term outcomes. Painful stimuli activate nociceptive pathways, from the periphery to the cortex, in neonates and behavioral responses form the basis for validated pain assessment tools. However, there is an increasing awareness of the need to not only reduce acute behavioral responses to pain in neonates, but also to protect the developing nervous system from persistent sensitization of pain pathways and potential damaging effects of altered neural activity on central nervous system development. Analgesic requirements are influenced by age-related changes in both pharmacokinetic and pharmacodynamic response, and increasing data are available to guide safe and effective dosing with opioids and paracetamol. Regional analgesic techniques provide effective perioperative analgesia, but higher complication rates in neonates emphasize the importance of monitoring and choice of the most appropriate drug and dose. There have been significant improvements in the understanding and management of neonatal pain, but additional research evidence will further reduce the need to extrapolate data from older age groups. Translation into improved clinical care will continue to depend on an integrated approach to implementation that encompasses assessment and titration against individual response, education and training, and audit and feedback.

Después de casi 40 años de eficacia ininterrumpida de la vancomicina, en 1997 se reportaron los primeros casos de fracaso terapéutico debido a cepas de Staphylococcus aureus con resistencia intermedia, denominadas VISA (concentración inhibitoria mínima, CIM, 8 a 16 ?g/ml, así como a cepas con resistencia heterogénea hVISA (CIM global = 4 ?g/ml, pero con subpoblaciones VISA, en las cuales la resistencia está mediada por engrosamiento de la pared celular y disminución de su entrecruzamiento, lo que afecta la llegada del antibiótico al blanco principal, los monómeros del peptidoglicano en la membrana plasmática. En 2002 se aisló la primera de las 3 cepas reportadas hasta la fecha con resistencia total al antibiótico, denominadas VRSA (CIM>32 ?g/ml, en las que se encontró el transposón Tn1546 proveniente de Enterococcus spp, responsable del reemplazo de la terminación D-Ala-D-Ala por D-Ala-Dlactato en los precursores de la pared celular con pérdida de la afinidad por el glicopéptido. Conclusiones. La resistencia a vancomicina es una realidad en S. aureus, mediada en el caso de VISA por alteraciones en la pared celular que atrapan el antibiótico antes de llegar al sitio de acción, y en el caso de VRSA, por transferencia desde Enterococcus spp. de genes que llevan a la modificación del blanco molecular.

    Full Text Available Abstract Background Neonatal sepsis is a significant cause of morbidity and mortality in neonates. Appropriate clinical diagnosis and empirical treatment in a given setting is crucial as pathogens of bacterial sepsis and antibiotic sensitivity pattern can considerably vary in different settings. This study was conducted at Bugando Medical Centre (BMC, Tanzania to determine the prevalence of neonatal sepsis, predictors of positive blood culture, deaths and antimicrobial susceptibility, thus providing essential information to formulate a policy for management of neonatal sepsis. Methods This was a prospective cross sectional study involving 300 neonates admitted at BMC neonatal unit between March and November 2009. Standard data collection form was used to collect all demographic data and clinical characteristics of neonates. Blood culture was done on Brain Heart Infusion broth followed by identification of isolates using conventional methods and testing for their susceptibility to antimicrobial agents using the disc diffusion method. Results Among 770 neonates admitted during the study period; 300 (38.9% neonates were diagnosed to have neonatal sepsis by WHO criteria. Of 300 neonates with clinical neonatal sepsis 121(40% and 179(60% had early and late onset sepsis respectively. Positive blood culture was found in 57 (47.1% and 92 (51.4% among neonates with early and late onset neonatal sepsis respectively (p = 0.466. Predictors of positive blood culture in both early and late onset neonatal sepsis were inability to feed, lethargy, cyanosis, meconium stained liquor, premature rupture of the membrane and convulsion. About 49% of gram negatives isolates were resistant to third generation cephalosporins and 28% of Staphylococcus aureus were found to be Methicillin resistant Staphylococcus aureus (MRSA. Deaths occurred in 57 (19% of neonates. Factors that predicted deaths were positive blood culture (p = 0.0001, gram negative sepsis (p = 0.0001 and

    Full Text Available In Western developed countries, Listeria monocytogenes is not an uncommon pathogen in neonates. However, neonatal listeriosis has rarely been reported in Taiwan. We describe two cases collected from a single medical institute between 1990 and 2005. Case 1 was a male premature baby weighing 1558 g with a gestational age of 31 weeks whose mother had fever with chills 3 days prior to delivery. Generalized maculopapular rash was found after delivery and subtle seizure developed. Both blood and cerebrospinal fluid culture collected on the 1st day yielded L. monocytogenes. In addition, he had ventriculitis complicated with hydrocephalus. Neurologic development was normal over 1 year of follow-up after ventriculoperitoneal shunt operation. Case 2 was a 28-weeks' gestation male premature baby weighing 1180 g. Endotracheal intubation and ventilator support were provided after delivery due to respiratory distress. Blood culture yielded L. monocyto-genes. Cerebrospinal fluid showed pleocytosis but the culture was negative. Brain ultrasonography showed ventriculitis. Sudden deterioration with cyanosis and bradycardia developed on the 8th day and he died on the same day. Neonatal listeriosis is uncommon in Taiwan, but has significant mortality and morbidity. Early diagnosis of perinatal infection relies on high index of suspicion in perinatal health care professionals. [J Formos Med Assoc 2007;106(2:161-164

    Hypoglycemia in the newborn may be associated with both acute decompensation and long-term neuronal loss. Studies of the cause of hypoglycemic brain damage and the relationship of hypoglycemia to disorders associated with hyperinsulinism have aided in our understanding of this common clinical finding. A recent consensus workshop concluded that there has been little progress toward a precise numerical definition of neonatal hypoglycemia. Nonetheless, newer brain imaging modalities have provided insight into the relationship between neuronal energy deficiency and central nervous system damage. Laboratory studies have begun to reveal the mechanism of hypoglycemic damage. In addition, there is new information about hyperinsulinemic hypoglycemia of genetic, environmental, and iatrogenic origin. The quantitative definition of hypoglycemia in the newborn remains elusive because it is a surrogate marker for central nervous system energy deficiency. Nonetheless, the recognition that hyperinsulinemic hypoglycemia, which produces profound central nervous system energy deficiency, is most likely to lead to long-term central nervous system damage, has altered management of children with hypoglycemia. In addition, imaging studies on neonates and laboratory evaluation in animal models have provided insight into the mechanism of neuronal damage.

Todos os animais desenvolveram mastite clínica superaguda. A bactéria foi recuperada de todas as glândulas desafiadas, sem diferença significativa no percentual de isolamento entre as espécies até o 11º dia pós-inoculação, porém com diferença (P<0,001 no 30º dia pós-inoculação. A CCS pelo método eletrônico e o CMT detectaram nas búfalas resposta mais intensa logo após a inoculação e diminuição mais rápida da contagem ao final do experimento, quando se comparou essa espécie com as vacas. Ambos os testes demonstraram correlação com a cultura bacteriana. Na avaliação da severidade da mastite, as médias do escore total, do escore da resposta local e do escore da resposta sistêmica foram mais elevadas na espécie bovina (P<0,05.

    Acute neonatal parotitis (ANP) is a rare condition, characterised by parotid swelling and other local inflammatory signs. The most common pathogen is Staphylococcus aureus, but other organisms can be implicated. We describe the case of a 13-day-old term newborn, previously healthy, with late-onset group B Streptococcus (GBS) bacteraemia with ANP, who presented with irritability, reduced feeding and tender swelling of the right parotid. Laboratory evaluation showed neutrophilia, elevated C reactive protein and procalcitonin, with normal serum amylase concentration. Ultrasound findings were suggestive of acute parotitis. Empiric antibiotic therapy was immediately started and adjusted when culture results became available. The newborn was discharged after 10 days, with clinical improvement within the first 72 h. Although S. aureus is the most common pathogen implicated in ANP, GBS should be included in the differential diagnosis. 2015 BMJ Publishing Group Ltd.

Which is recognized as a potential source of infection and a high risk factor for subsequent invasive infections. The prevalence of nasal carriage of this germ in disabled children in Paraguay is not known, thus contributing to the knowledge of their frequency and evaluate the profile of sensitivity to common antimicrobials was conducted this study, from May to July 2015.  Objective: to determine the prevalence of Staphylococcus aureus nasal carriage and profile of antimicrobial resistance in disabled children. Materials and Methods: A descriptive cross-sectional study in which 80 nasal swabs of children, who attended the service laboratory of SENADIS (Secretaria Nacional por los Derechos Humanos de las Personas con Discapacidad. The identification and sensitivity of germ was accomplished by conventional testing.  Results: 80 pediatric patients, 46 boys and 34 girls. 18 isolates of Staphylococcus aureus were obtained, corresponding to a prevalence of 22,5%. Susceptibility testing indicated that 14 strains were MSSA (Methicillin – Sensitive Staphylococcus aureus and 4 RMSA ( Methicillin- resistant Staphylococcus aureus. Conclusion: The prevalence of Staphylococcus aureus in a population with its own characteristics provides valuable data for the epidemiology, reflecting the need for continued vigilance and take steps to reduce associated infections. The detection of RMAR evidences their progress; it is important to evaluate the empirical treatment to primary care.

  7. Neonatal euthanasia.

    2009-12-01

    Despite advances in the care of infants, there remain many newborns whose medical conditions are incompatible with sustained life. At times, healthcare providers and parents may agree that prolonging life is not an appropriate goal of care, and they may redirect treatment to alleviate suffering. While pediatric palliative treatment protocols are gaining greater acceptance, there remain some children whose suffering is unrelenting despite maximal efforts. Due to the realization that some infants suffer unbearably (ie, the burdens of suffering outweigh the benefits of life), the Dutch have developed a protocol for euthanizing these newborns. In this review, I examine the ethical aspects of 6 forms of end of life care, explain the ethical arguments in support of euthanasia, review the history and verbiage of the United States regulations governing limiting and withdrawing life-prolonging interventions in infants, describe the 3 categories of neonates for whom the Dutch provide euthanasia, review the published analyses of the Dutch protocol, and finally present some practical considerations should some form of euthanasia ever be deemed appropriate.

Desta maneira, através de estudo prospectivo desenvolvido na década de 1970, foram avaliadas 77 crianças portadoras de colestase neonatal prolongada para estabelecer o diagnóstico diferencial entre atresia biliar e hepatite neonatal e, numa segunda fase, 108 crianças, visando esclarecer a etiopatogenia da colestase neonatal prolongada. Os resultados do diagnóstico diferencial revelaram que, dos 18 atributos avaliados, apenas oito mostraram-se bons indicadores de atresia biliar, em ordem decrescente: ductos proliferados (espaço-porta, fibrose (espaço-porta, colestase (espaço-porta, cor das fezes -- acolia, hepatomegalia, colestase canalicular (lóbulo, infiltrado (espaço-porta, células gigantes (lóbulo. Estes oito atributos foram então compostos, mediante uma ponderação, em um único indicador de grande poder discriminativo, capaz de decidir o diagnóstico diferencial em 99% dos casos.

K+ is the most important intracellular cation and normal serum K+ is stabilized between 3.5 and 5.5 mEq/L. Hypokalemia may be caused by increased renal losses, increased extrarenal (gastrointestinal losses, redistribution or prolonged insufficient K+ intake. Clinical signs and symptoms occur as the result of functional changes in striated muscle, smooth muscle, and the heart. Hypokalemia is usually asymptomatic when K+ levels are between 3.0 and 3.5 mEq/L; however, there may sometimes be slight muscle weakness. Moderate hypokalemia is observed when serum K+ is between 2.5 and 3.0 mEq/L. Proximal muscle weakness is observed most commonly in lower extremities; cranial muscles are normal, but constipation and distention are prominent. Severe hypokalemia develops when serum K+ falls below 2.5 mEq/L. Rhabdomyolysis, myoglobinuria, severe muscle weakness, paralysis, respiratory distress, and respiratory arrest are observed. The clinical signs and symptoms may be unremarkable in cases of chronically developing hypokalemia; however, appropriate treatment is essential when serum K+ level falls below 2.5 mEq/L as the most dangerous complication of hypokalemia is fatal cardiac arrythmia, and changes visible with electrocardiography may not always correlate with the level of hypokalemia. Sodium (Na+, K+, chloride (Cl-, bicarbonate, creatinine, blood sugar, magnesium (Mg, plasma renin activity, aldosterone, and blood gases should be investigated by laboratory testing.

    1987-01-01

    The clinical examination of the CNS in the neonate is often difficult in cases of complex pathology. Diagnostic imaging of the neonatal brain has become extremely useful and in the last decade has developed in two main directions: CT and US. MR imaging has been used recently with varying success in the diagnosis of pathology in the neonatal brain. Despite technical difficulties, this imaging method is likely to become increasingly important in the neonate. The paper examines the normal neonatal brain anatomy as seen with the different modalities, followed by pathologic conditions. Attention is directed to the common pathology, in asphyxiated newborns, the patholphysiology of intraventicular hemorrhage and periventricular leukomalacia in the preterm neonate, and hypoxic-ischemic brain injury in the term neonate. Pitfalls, artifacts, and problems in image interpretation are illustrated. Finally, the subsequent appearance of neonatal pathology later in infancy and childhood is discussed

    Staphylococcal scalded skin syndrome (SSSS) is a toxin-mediated exfoliating skin condition predominated by desquamation and blistering. Neonatal outbreaks have already been reported; however, our outbreak highlights the potential for SSSS following neonatal health promotion measures such as intra-muscular vitamin K administration and metabolic screening (heel prick) as well as effective case containment measures and the value of staff screening. Between February and June 2007, five confirmed cases of neonatal SSSS were identified in full-term neonates born in an Irish regional maternity hospital. All infants were treated successfully. Analysis of contact and environmental screening was undertaken, including family members and healthcare workers. Molecular typing on isolates was carried out. An outbreak control team (OCT) was assembled and took successful prospective steps to prevent further cases. All five Staphylococcus aureus isolates tested positive for exfoliative toxin A, of which two distinct strains were identified on pulsed-field gel electrophoresis analysis. Two cases followed staphylococcal inoculation during preventive measures such as intra-muscular vitamin K administration and metabolic screening (heel prick). None of the neonatal isolates were methicillin resistant. Of 259 hospital staff (70% of staff) screened, 30% were colonised with S. aureus, and 6% were positive for MRSA carriage. This is the first reported outbreak of neonatal SSSS in Ireland. Effective case containment measures and clinical value of OCT is demonstrated. Results of staff screening underlines the need for vigilance and compliance in hand disinfection strategies in maternity hospitals especially during neonatal screening and preventive procedures.

    The aim of the present study was to evaluate the effects of antibiotics on the condition of babies born with risk of neonatal sepsis. From March, 2014 to February, 2015, 200 neonates born with risk factors of septicemia in the Neonatal Intensive Care Unit at Xuzhou Central Hospital, were enrolled in the present study. Venous blood samples were collected within 6 h of birth using aseptic technique. Part of the blood specimens were cultured using BACTEC PEDS PLUS/F Culture Vials. Subsequently, the subcultures were prepared from each presumptive positive vial and bacterial isolates were identified. The remaining portion was used to measure the level of C-reactive protein (CRP) and total leukocyte count (TLC). The result showed that 32% of neonates were infected, of whom, 21.9% had Staphylococcus aureus , 21.9% had Acinetobacter Baumanni , and 12.5% had Klebsiella pneumoniae . Additionally, Staphylococcus epidermis , Enteroccus spp ., Pseudomonas aeruginosa and E. coli was isolated from 9.4, 7.8, 6.3 and 4.7% of neonates, respectively. The neonates enrolled in the present study had ≥1 risk factor for neonatal sepsis, and the average number of risk factors was 1.95 per neonate. Neonates (39.1%) with positive blood culture results, had a CRP level >0.8 mg/dl, and 12.5% was shown to have an abnormal increase in their leukocyte counts. The association between leukocyte counts and blood culture results was not statistically significant. Of the neonates with positive blood cultures 45.3% died within 7 days after birth, while there was no mortality among those with negative culture results. The results indicate that in the presence of risk factors for sepsis, irrespective of clinical features of septicemia, neonatal sepsis screening should be performed. Rational and appropriate use of antibiotics may minimize the emergence of multidrug resistant bacteria in neonatal units.

    2014-01-01

    Full Text Available Acute neonatal parotitis (ANP is a very rare disease. Most cases are managed conservatively; early antibiotics and adequate hydration may reduce the need for surgery. The most common cause of ANP is Staphylococcus aureus. We report a rare case of acute neonatal parotitis with late-onset septic shock due to Streptococcus agalactiae. The diagnosis was confirmed with ultrasound and isolation of Streptococcus agalactiae from blood culture. The patient was treated successfully with 10 days of intravenous antibiotics and supportive measures. Despite being rare, streptococcal ANP should be considered in the etiological diagnosis of neonatal sepsis. Early diagnosis and appropriate antibiotic might prevent serious complications.

    2012-01-01

    Full Text Available Objective: to study the causes of acute intranatal hypoxia and reveal a relationship of placental changes to respiratory failure (RF in newborn infants. Subjects and methods. The investigation included 252 neonates with the complicated course of an early neonatal period. Their gestational age was 26 weeks to 40 weeks, birth weight varied from 850 g to 4100 g. 95.3% of the newborn infants were born with a low Apgar score and RF, which required mechanical ventilation immediately after birth. The neonatal status was clinically evaluated; the values of blood gas composition and acid-base balance were recorded; the pathogen was discharged from the tracheobronchial tree; chest X-ray survey and placental morphological examination were performed. Results. The main cause of neonatal respiratory failure is chronic intrauterine hypoxia caused by placental inflammatory changes and fetal-placental blood circulatory disorders, which gives rise to preterm delivery, cerebral hemodynamic disorders, and neonatal amniotic fluid aspiration. Bacteriological examination of tracheobronchial aspirations showed that no microflora growth occured in the majority of the newborns acute intranatal hypoxia. Enterococcus faecalis and Staphylococcus epidermidis were isolated in 12.3% and 8.7%, respectively. Growth of в-hemolytic streptococcus was observed in 2.8% of cases. The rate of microbial association specific only for rate premature infants with neonatal respiratory distress syndrome (NRDS was 4.8%. Conclusion. Placental changes causing fetal-placental circulatory disorders were ascertained to be responsible for acute intranatal and postnatal neonatal hypoxia. Placental inflammatory changes occurred in the majority of cases, as confirmed by bacteriological examinations of neonatal infants. Isolation of the varying microbial flora in infants with RF to a greater extent is, indicative of the infectious process occurring in the maternal body. Key words: acute intranatal

    Human milk is the preferred nutrition for neonates and a source of bacteria. Research aim: The authors aimed to characterize the molecular epidemiology and genetic content of staphylococci in the human milk of mothers of preterm and term neonates. Staphylococci were isolated once per week in the 1st month postpartum from the human milk of mothers of 20 healthy term and 49 preterm neonates hospitalized in the neonatal intensive care unit. Multilocus variable-number tandem-repeats analysis and multilocus sequence typing were used. The presence of the mecA gene, icaA gene of the ica-operon, IS 256, and ACME genetic elements was determined by PCR. The human milk of mothers of preterm compared with term neonates had higher counts of staphylococci but lower species diversity. The human milk of mothers of preterm compared with term neonates more often contained Staphylococcus epidermidis mecA (32.7% vs. 2.6%), icaA (18.8% vs. 6%), IS 256 (7.9% vs. 0.9%), and ACME (15.4% vs. 5.1%), as well as Staphylococcus haemolyticus mecA (90.5% vs. 10%) and IS 256 (61.9% vs. 10%). The overall distribution of multilocus variable-number tandem-repeats analysis (MLVA) types and sequence types was similar between the human milk of mothers of preterm and term neonates, but a few mecA-IS 256-positive MLVA types colonized only mothers of preterm neonates. Maternal hospitalization within 1 month postpartum and the use of an arterial catheter or antibacterial treatment in the neonate increased the odds of harboring mecA-positive staphylococci in human milk. Limiting exposure of mothers of preterm neonates to the hospital could prevent human milk colonization with more pathogenic staphylococci.

    A study carried out in the Maternity Hospital, Kuala Lumpur over a 6 year period from 1986 to 1991, showed that the annual rates of septicaemia ranged from 5.2 to 10.2/100 admissions. Septicaemia accounted for between 11.0 to 30.4% of all neonatal deaths. The case fatality ratios ranged from 23.0 to 52.2%, being highest in 1989 when basic facilities were compromised. Low birthweight neonates accounted for 55.5% of those with septicaemia. The most common causative organisms were Staphylococcus epidermidis and Staphylococcus aureus in 1986 and 1987, but from 1988 Klebsiella species became the most common. More than 50% of neonatal septicaemia occurred after the age of 2 days. The results of the study demonstrated the dynamism of infection control: when control measures introduced earlier were not sustained, outbreaks of nosocomial infection recurred or worsened.

    Full Text Available Introduction: Neonatal sepsis is a leading cause of neonatal mortality and morbidity in the world. The objective of the current study was to detect the common causative microorganisms of neonatal sepsis and their antimicrobial resistance patterns in a rural secondary hospital in Tamil Nadu, India. Materials and Methods: Neonates (0–28 days admitted to this newborn care unit from October 2013 to September 2015, with a diagnosis of probable sepsis were studied. All the enrolled babies had blood cultures taken and were followed up till final outcome, which was discharge or death, irrespective of culture result. Univariate analysis was performed for factors associated with culture positivity, generating odds ratios, and confidence intervals. Results: Among the 107 babies with a diagnosis of probable sepsis, 28 (26.2% had shown bacteria in culture. The majority (94.4% were of early-onset sepsis. The predominant organisms were Staphylococcus aureus (10/28 and Klebsiella (6/28. 100% of Gram-negative bacilli and 90% of Staphylococcus were resistant to Ampicillin. Gentamicin resistance among Gram-negative bacilli and Staphylococcus was 52.9% and 20%, respectively, while third-generation cephalosporin resistance was 31.2% and 20%, respectively. Among the neonates diagnosed as probable sepsis, idiopathic prematurity (P = 0.007 was found to have a statistically significant association with culture-positive sepsis. Conclusion: The culture positivity rate among the neonates with probable sepsis in the current study was 26%. An alarmingly high degree of antibiotic resistance observed calls for robust infection control practices and an urgent evaluation and development of individual and national antibiotic policies for neonatal sepsis.

    Full Text Available Premature rupture of membranes (PROM is one of the most common complications of pregnancy that has a major impact on neonatal outcomes. With respect to racial, nutritional and cultural differences between developed and developing countries, this study was conducted to detect the prevalence of neonatal complications following PROM and the role of the duration of rupture of membranes in producing morbidities and mortalities in these neonates in our hospital. Among 2357 pregnant women, we found 163 (6.91% cases of premature rupture of the fetal membranes in Tehran Vali-e-Asr Hospital during April 2001 to April 2002. Route of delivery was cesarean section in 65.6% of women. Urinary tract infection occured in 1.8%, maternal leukocytosis and fever in 20.2% and 5.5%, chorioamnionitis in 6.1%, fetal tachycardia in 1.2% and olygohydramnios in 4.9%. Gestational age in 138 (86% of neonates was less than 37 completed weeks. Thirty five infants (21.47% had respiratory distress syndrome and 33 (20.245% had clinical sepsis. Pneumonia in 6 (3.7% and skeletal deformity in 7 (4.294% were seen. Rupture of membrane of more than 24 hours duration occurred in 71 (43.6% of the patients. Comparison of morbidities between two groups of neonates and their mothers according to the duration of PROM (less and more than 24 hours showed significant differences in NICU admission, olygohydramnios, maternal fever, leukocytosis and chorioamnionitis rates (p24 hr of PROM with an odds ratio of 2.68 and 2.73, respectively. Positive blood and eye cultures were detected in 16 cases during 72 hours of age. Staphylococcus species, klebsiella, E.coli and streptococcus were the predominant organisms among positive blood cultures. Mortality was seen in 18 (11% of neonates because of respiratory failure, disseminated intravascular coagulation, septic shock, and a single case of congenital toxoplasmosis. In this study, the prevalence of prematurity, sepsis and prolonged rupture of membrane

    Full Text Available OBJETIVO: Relatar associação infreqüente de patologia que cause aumento considerável de produção de bilirrubina e outra diminuição importante na sua excreção. DESCRIÇÃO: Mãe tercigesta, Rh negativo. Na primeira gestação, gerou recém-nascido normal, de termo, não tendo recebido imunoglobulina humana anti-RhD. A segunda gestação complicou-se por isoimunização Rh, dando à luz neonato de termo, o qual necessitou três exsanguinotransfusões e faleceu com 8 dias de vida. Na gestação atual, conseguiu dar à luz a termo recém-nascido tipo ORh positivo, Coombs direto positivo, bilirrubina de cordão 6,5 mg/dl e hematócrito 44%. Com 5 horas de vida, estava ictérico, tendo sido iniciados fenobarbital (por 3 dias e fototerapia intensiva. A hiperbilirrubinemia foi logo controlada, porém ascendia rapidamente sempre que a fototerapia era suspensa. No 10° dia de vida, a criança foi transfundida por anemia importante. Em vista da persistência da icterícia, no 13° dia de vida pensou-se em associação com síndrome de Gilbert, e o seqüenciamento de DNA foi solicitado. O resultado mostrou genótipo mutante homozigoto UDPT1A1[TA]7TAA. Permaneceu em fototerapia até o 17° dia de vida. Recebeu alta no dia seguinte, após controle de bilirrubinemia. Voltou para acompanhamento ambulatorial e apresentou desenvolvimentos pondo-estatural e neurológico normais. COMENTÁRIOS: O caso ressalta a importância da associação do aumento de produção/diminuição de excreção de bilirrubina na gênese de hiperbilirrubinemias prolongadas, intensas e passíveis de causar kernicterus, se não tratadas vigorosamente. Demonstra, ainda, a eficácia da fototerapia intensiva, reduzindo os riscos de tratamentos mais agressivos. Ressalta, também, a importância do acompanhamento das icterícias neonatais até a completa remissão dos sintomas.OBJECTIVE: To report on an infrequent association of pathologies causing considerable increase in bilirubin

    A cohort study of neonatal mortality (N = 106) in white singleton births (N = 14,486) in Utah for January-June 1975 was conducted. Using membership and activity in the Church of Jesus Christ of Latter-day Saints (LDS or Mormon) as a proxy for parental health practices, i.e., tobacco and alcohol abstinence, differential neonatal mortality rates were calculated. The influence of potential confounding factors was evaluated. Low activity LDS members were found to have an excess risk of neonatal death five times greater than high activity LDS, with an upper bound of a two-sided 95% confidence interval of 7.9. The data consistently indicate a lower neonatal mortality rate for active LDS members. Non-LDS were found to have a lower rate than either medium or low activity LDS.

    Full Text Available The past 2-3 decades have seen dramatic changes in the approach to pain management in the neonate. These practices started with refuting previously held misconceptions regarding nociception in preterm infants. Although neonates were initially thought to have limited response to painful stimuli, it was demonstrated that the developmental immaturity of the central nervous system makes the neonate more likely to feel pain. It was further demonstrated that untreated pain can have long-lasting physiologic and neurodevelopmental consequences. These concerns have resulted in a significant emphasis on improving and optimizing the techniques of analgesia for neonates and infants. The following article will review techniques for pain assessment, prevention, and treatment in this population with a specific focus on acute pain related to medical and surgical conditions.

    Ultrasonography (US) is as an important tool for differentiation of obstructive and non-obstructive causes of jaundice in infants and children. Beyond two weeks of age, extrahepatic biliary atresia and neonatal hepatitis are the two most common causes of persistent neonatal jaundice: differentiation of extrahepatic biliary atresia, which requires early surgical intervention, is very important. Meticulous analysis should focus on size and configuration of the gallbladder and anatomical changes of the portahepatis. In order to narrow the differential diagnosis, combined approaches using hepatic scintigraphy, MR cholangiography, and, at times, percutaneous liver biopsy are necessary. US is useful for demonstrating choledochal cyst, bile plug syndrome, and spontaneous perforation of the extrahepatic bile duct

    Neonatal lupus erythematosus (NLE) is an uncommon disease of the neonate. It is believed to be caused by the transplacental passage of maternal autoantibodies to the ribonucleoproteins (Ro\\/SSA, La\\/SSB or rarely U RNP) as these are almost invariably present in NLE sera. The most common clinical manifestations include cutaneous lupus lesions and congenital complete heart block. Hepatobiliary and haematologic abnormalities are reported less frequently. We describe a patient with cutaneous NLE to illustrate and raise awareness of the characteristic annular eruption of this condition. We also emphasize the need for thorough investigation for concomitant organ involvement and for maternal education regarding risk in future pregnancies.

    In-hospital transmission of methicillin-susceptible Staphylococcus aureus (MSSA) among neonates remains enigmatic. We describe the epidemiology of MSSA colonization and infection in a 30-bed neonatal ward. Multimodal outbreak investigation A public 800-bed tertiary care university hospital in Switzerland Investigations in 2012-2013, triggered by a MSSA infection cluster, included prospective MSSA infection surveillance, microbiologic screening of neonates and environment, onsite observations, and a prospective cohort study. MSSA isolates were characterized by pulsed-field gel electrophoresis (PFGE) and selected isolates were examined for multilocus sequence type (MLST) and virulence factors. Among 726 in 2012, 30 (4.1%) patients suffered from MSSA infections including 8 (1.1%) with bacteremia. Among 655 admissions in 2013, 13 (2.0%) suffered from MSSA infections including 2 (0.3%) with bacteremia. Among 177 neonates screened for S. aureus carriage, overall 77 (44%) tested positive. A predominant PFGE-1-ST30 strain was identified in 6 of 30 infected neonates (20%) and 30 of 77 colonized neonates (39%). This persistent clone was pvl-negative, tst-positive and belonged to agr group III. We found no environmental point source. MSSA carriage was associated with central vascular catheter use but not with a particular midwife, nurse, physician, or isolette. Observed healthcare worker behavior may have propagated transmission via hands and fomites. Despite multimodal interventions, clonal transmission and colonization continued and another clone, PFGE-6-ST5, became predominant. Hospital-acquired MSSA clones represent a high proportion of MSSA colonization but not MSSA infections in neonate inpatients. In contrast to persisting MSSA, transmission infection rates decreased concurrently with interventions. It remains to be established whether eradication of hospital-acquired MSSA strains would reduce infection rates further.

    Full Text Available INTRODUCTION: Bacterial infections account for a huge proportion of neonatal deaths worldwide. The problem of antibiotic resistance among common bacterial pathogens mainly the gram negative bacteria is emerging globally which is of more serious concern in developing countries like Nepal. METHODS: A one year retrospective hospital based study was carried out to analyze the results of neonatal blood, cerebrospinal fluid, urine, stool and surface cultures and to look into the sensitivity pattern of the commonly used antibiotics. RESULTS: The positive yield of blood, urine, eye swab and CSF cultures were 19.56%, 38.5%, 60% and 0.36% respectively. The most common isolates in the blood culture were coagulase negative Staphylococcus, Acinetobacter, Enterobacter and non-haemolytic Streptococcus. A significant percent of the isolates were resistant to the first line antibiotics. Among the gram negative isolates more than 30% are resistant to cefotaxime and more than 50% are resistant to gentamicin. During the one year period we had Nursery outbreaks of methicillin resistant Staphylococcus aureus and Salmonella infections. With the help of environmental cultures we were able to trace the source and intervene appropriately. CONCLUSIONS: Continuous surveillance for antibiotic susceptibility, rational use of antibiotics and the strategy of antibiotic cycling can provide some answers to the emerging problem of antibiotic resistance.

    Bacterial infections account for a huge proportion of neonatal deaths worldwide. The problem of antibiotic resistance among common bacterial pathogens mainly the gram negative bacteria is emerging globally which is of more serious concern in developing countries like Nepal. A one year retrospective hospital based study was carried out to analyze the results of neonatal blood, cerebrospinal fluid, urine, stool and surface cultures and to look into the sensitivity pattern of the commonly used antibiotics. The positive yield of blood, urine, eye swab and CSF cultures were 19.56%, 38.5%, 60% and 0.36% respectively. The most common isolates in the blood culture were coagulase negative Staphylococcus, Acinetobacter, Enterobacter and non-haemolytic Streptococcus. A significant percent of the isolates were resistant to the first line antibiotics. Among the gram negative isolates more than 30% are resistant to cefotaxime and more than 50% are resistant to gentamicin. During the one year period we had Nursery outbreaks of methicillin resistant Staphylococcus aureus and Salmonella infections. With the help of environmental cultures we were able to trace the source and intervene appropriately. Continuous surveillance for antibiotic susceptibility, rational use of antibiotics and the strategy of antibiotic cycling can provide some answers to the emerging problem of antibiotic resistance.

    The incidence of coagulase-negative staphylococci reported as causative agents of nosocomial infections has risen in the last decade. The aim of this study was to characterize biofilm formation, antibiotic resistance, SCCmec type, and genetic relatedness in clinical isolates of Staphylococcus cohnii, Staphylococcus hominis, and Staphylococcus sciuri recovered from humans. Clinically relevant isolates of S. cohnii (n = 15), S. hominis (n = 9), and S. sciuri (n = 6), were collected from patients. Biofilm formation was evaluated using crystal violet staining, drug susceptibility was assessed using the broth microdilution method, and methicillin resistance was measured using the cefoxitin disk test. SCCmec was typed using 2 different methodologies, and genetic relatedness was determined by pulsed-field gel electrophoresis (PFGE). Sixty percent (9/15) of S. cohnii, 33% (3/9) of S. hominis, and 50% (3/6) of S. sciuri isolates were categorized as weak producers of biofilm. None of the isolates were resistant to vancomycin or linezolid. All 3 species showed a high resistance (> 66%) to ampicillin, levofloxacin, erythromycin, and ceftriaxone, and the majority of the isolates were methicillin-resistant. PFGE revealed that the S. cohnii isolates comprised 1 dominant clone. The S. cohnii, S. hominis, and S. sciuri isolates analyzed in this study showed a high methicillin resistance and resistance to other antimicrobials. The results of this study strongly suggest that coagulase-negative staphylococci harbour new SCCmec elements. We report the first case of a clone of S. cohnii associated with human disease.

    Full Text Available The aims of this study were to determine endemic and epidemic infection due to Gram-negative bacilli, risk factors associated with colonization and infection by these organisms and the resistance phenotypes (ESBL, AmpC in neonates admitted in a High Risk Nursery. The study was conducted during a 21 month period and included: a prospective study to evaluate the neonates with hospital infection and the use of third-generation cephalosporins; a case-control study to determine the risk factors associated with colonization/infection. Rectal and oropharynx cultures were also performed in four opportunities (September and November 2001, February and August 2002. The isolates for which the resistance of ceftazidime was 2 mg/mL were suspected of producing ESBL or AmpC b-lactamases. The incidence of infection by Gram-negative bacilli was 2.4% (89/3.708 neonates, and sepsis (35.9% and conjunctivitis (31.4% were the most common infections. The endemic infections were more prevalent (73.9% and usually associated with Enterobacteriaceae (95.5%, being these organisms also related to colonization, corresponding mainly to isolates of Enterobacter spp. and Klebsiella spp. Two outbreaks of Pseudomonas aeruginosa (n=10 and Acinetobacter baumannii (n=11 were identified during the survey. Univariate analysis showed that risk factors for Gram-negative bacilli infection considered significant included: the length of stay before infection/colonization, exposure to antimicrobial agents, mechanical ventilation, central venous catheters, parenteral nutrition and surgery. The majority of resistance to ceftazidime among Enterobacteriaceae isolates (80.9% was from ESBL phenotype. Administration of third-generation cephalosporins (ceftriaxone led to the emergence of these multiresistant Gram-negative bacilli in the neonatal unit.Os objetivos deste estudo foram determinar infecções endêmicas e epidêmicas por bacilos Gram-negativos, fatores de risco associados a coloniza

    Full Text Available Background: There is not much published literature on neonatal septicemia available for the Sub-Himalayan region of North India. Hence, we undertook this study to find out the bacteriological profile and antibiotic sensitivity pattern of neonatal septicemia in the neonatal Intensive Care Unit. Material and Methods: Blood cultures were performed for all clinically suspected neonatal septicemia cases for 1-year. Identification of all pathogenic isolates was followed by antibiotic sensitivity testing. Results: We did blood cultures for 450 neonates and 42% were culture positive. Early onset sepsis were 92 (49% and 96 (51% were late onset sepsis. Gram-positive isolates were 60% and 40% were Gram-negative. Staphylococcus aureus (40%, coagulase negative Staphylococcus species (16%, non-fermenter group of organisms (NFGOs (15%, and Klebsiella pneumoniae (10% were the main isolates. Nasal cannula 101 (54%, birth asphyxia 91 (48%, and prematurity 73 (38% were the prominent risk factors associated with septicemia. Gram-positive organisms were highly resistant to penicillin (87% whereas Gram-negative isolates showed high resistance to third generation cephalosporins (53–89% and aminoglycosides (50–67%. The S. aureus isolates were methicillin-resistant in 41% whereas extended spectrum beta lactamase production was seen in 48% Gram-negative isolates.Conclusion: Our study highlights the recent emergence of Gram-positive organisms as predominant cause of neonatal septicemia in this part of Sub-Himalayan region, along with the review of literature which shows similar results from North India and rest of the world too. Though Gram-negative bacteria still remain the main cause of mortality in neonatal septicemia, we want to dispel the common notion among practitioners that they are the predominant isolates in neonatal septicemia.

    2012-01-01

    Full Text Available Objective: to reveal a relationship of placental inflammatory changes to bacterial infection in premature neonates with respiratory failure. Material and methods. Bronchoalveolar aspirate was bacteriologically studied in 157 premature neonates with respiratory distress syndrome (NRDS; the total and differential leukocyte counts were measured in their peripheral blood. The levels of the cytokines IL-1^3, IL-4, IL-6, and TNF-a were studied in different biological fluids of mothers and their babies; the placentas were also morphologically examined. Results. An analysis of bacterial cultures from the tracheobronchial tree revealed no growth of bacterial microflora in 61.8% of cases, Enterococcus faecalis and Staphylococcus epidermidis were isolated in 6.4 and 8.3% of the infants, respectively; Staphylococcus haemolyticus, Staphylococcus capitis, Enterobacter agglomerans, and hemolytic group A Streptococcus were seen in 1.9% each; moreover, 1.3% of the newborn infants were found to have Bacillus spp., Staphylococcus aureus, Escherichia coli, Acinetobacter spp., and Serratia marcescens. Other microorganisms and a microbial association were encountered in 8.9% of cases. Placental morphological examination revealed different inflammatory changes concurrent with chronic and acute placental insufficiency. The investigation demonstrated that the maternal peripheral plasma levels of IL-1^, IL-4, IL-6, and TNF-a were within the physiological range at the end of the first period of delivery. The amniotic fluid displayed elevated IL-6 and TNF-a concentrations and normal IL-4 and IL-1e levels, suggesting that there was an intrauterine inflammatory process. Conclusion. Premature birth is associated with various placental inflammatory changes, which causes intrauterine stimulation of macrophages in the chorionic villi. Specific immune defense mechanisms that prevent the development of a fetal infectious process, i.e. the maternal infectious process, may induce

    Neonatal infections carry a heavy burden of morbidity and mortality. Poor practice can result in unintentional colonisation of medical equipment with potentially pathogenic organisms. This study will determine the prevalence and type of bacterial contamination on exposed neonatal resuscitation equipment in different clinical settings and explore simple measures to reduce contamination risk. A survey determined the rates of resuscitation equipment usage. All environmentally exposed items were identified on resuscitaires hospital-wide and swabbed for bacterial contamination. A new cleaning and storage policy was implemented and the prevalence of environmentally exposed equipment re-measured post-intervention. Resuscitation equipment was used in 28% of neonatal deliveries. Bacterial colony forming units were present on 44% of the 236 exposed equipment pieces swabbed. There was no significant difference in contamination rates between equipment types. Coagulase negative staphylococcus was the most prevalent species (59 pieces, 25%) followed by Escherichia coli and Enterobacter cloacae (20 pieces, 9% each). Opened items stored inside plastic remained sterile, whilst those in low-use areas had significantly less contamination than those in high-use areas (22% vs. 51%, P reducing microbial colonisation opportunities. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Objective: To determine the frequency of inducible clindamycin resistance in clinical isolates of Staphylococcus species by phenotypic D-test. Study Design: Observational study. Place and Duration of Study: Ziauddin University Hospital, Karachi, from July to December 2011. Methodology: Consecutive clinical isolates of Staphylococcus species were collected and identified by conventional microbiological techniques. Antimicrobial susceptibility testing and inducible clindamycin resistance was carried out by performing D-test using CLSI criteria. Methicillin resistance was detected by using Cefoxitin disk as a surrogate marker. Statistical analysis was performed by SPSS version-17. Results: A total of 667 clinical isolates of Staphylococcus species were obtained during the study period. In these isolates, 177 (26.5%) were Staphylococcus aureus, and 490 (73.5%) were coagulase negative Staphylococci. The total frequency of inducible clindamycin resistance among isolates of Staphylococcus species was 120/667 (18%). Frequency of inducible clindamycin resistance among coagulase negative Staphylococci group and Staphylococcus aureus group were 18.57% and 16.38% respectively. Median age of patients in D-test positive group was 19.5 (1 - 54) years. Conclusion: The frequency of inducible clindamycin resistance among Staphylococcus species may differ in different hospital setup. Clinical microbiology laboratories should implement testing simple and effective D-test on all Staphylococcus species. D-test positive isolates should be reported clindamycin resistant to decrease treatment failure. (author)

    This study included 502 staphylococcus strains; Staphylococcus saprophyticus (297 strains) S. cohnii (47), S. xylosus (10), S. epidermidis (67) and S. aureus (81). Mitomycin C induction was performed on 100 isolates of S. saprophyticus and all induced strains were reacted with each other. Twenty-six strains proved to be lysogenic. Phages were propagated and titrated. With 12 of the phages there were three frequent associations, named lytic groups A, B and C, which included 75% of all typable strains. Typability of the system was 45% and reproducibility was between 94.2% and 100%. Phages did not lyse S. aureus and S. epidermidis strains, but they lysed S. saprophyticus and only rare strains of other novobiocin resistant species. Effective S. saprophyticus typing serves ecological purposes and tracing the origin of urinary strains from the skin or mucous membranes. Phage typing in association with plasmid profiling previously described, are anticipated as complementary methods with strong discriminatory power for differentiating among S. saprophyticus strains.

    BackgroundWe aimed to determine the genetic relatedness between Staphylococcus epidermidis colonizing breast milk (BM) and BM-fed neonates during the first month of life.MethodsS. epidermidis was isolated from the stool and skin swabs of 20 healthy term and 49 preterm neonates hospitalized in the neonatal intensive care unit and from the BM of mothers once a week and typed by multilocus variable-number tandem-repeat analysis. Virulence-related genes were determined by PCR.ResultsThe gut (95%) and skin (100%) of term neonates were colonized with strains genetically similar to those in BM and carrying mecA and IS256 at low rate (both skin (34.7%) and in the gut in the first week of life (14.3%), but the prevalence of mecA (>90.6%) and IS256 (>61.7%) was high. By the fourth week, in the gut of preterm neonates the prevalence of mecA (73.8%) and IS256 (18.4%) decreased, but colonization with strains genetically similar to those in BM increased (83.7%).ConclusionDuring early life, the skin and gut of preterm neonates is colonized with S. epidermidis that is distinct from strains found in BM, but gradually the gut is enriched with strains genetically similar to those in BM, as in term neonates.

    2014-06-01

    Neonatal opioid withdrawal syndrome is common due to the current opioid addiction epidemic. Infants born to women covertly abusing prescription opioids may not be identified as at risk until withdrawal signs present. Buprenorphine is a newer treatment for maternal opioid addiction and appears to result in a milder withdrawal syndrome than methadone. Initial treatment is with nonpharmacological measures including decreasing stimuli, however pharmacological treatment is commonly required. Opioid monotherapy is preferred, with phenobarbital or clonidine uncommonly needed as adjunctive therapy. Rooming-in and breastfeeding may decease the severity of withdrawal. Limited evidence is available regarding long-term effects of perinatal opioid exposure. Copyright © 2014 Elsevier Inc. All rights reserved.

    Healy, Patricia; Fallon, Anne

    This article reviews the origins and evolution of neonatology and considers the role of the neonatal nurse within this specialty. Neonatal nurses are a vital part of the neonatal team that provides care for sick babies. The nursing care required by sick babies and their families on a neonatal unit can be variable and complex. The past century has seen significant changes in the role of the neonatal nurse. This has come about through dramatic technological developments on neonatal units, an increased understanding of neonatal physiology and pathology, changes in the education of neonatal nurses, and active and ongoing clinical research within the specialty. The resulting significant advances in neonatal care, including that provided by neonatal nurses, have made a crucial and steadfast contribution to marked improvements in neonatal outcomes.

    Plain radiographs for infants in the neonatal intensive care unit are obtained using the portable X-ray equipment in order to evaluate the neonatal lungs and also to check the position of the tubes and catheters used for monitoring critically-ill neonates. Neonatal respiratory distress is caused by a variety of medical or surgical disease conditions. Clinical information about the gestational week, respiratory symptoms, and any events during delivery is essential for interpretation of the neonatal chest radiographs. Awareness of common chest abnormality in the prematurely born or term babies is also very important for chest evaluation in the newborn. Furthermore, knowledge about complications such as air leaks and bronchopulmonary dysplasia following treatment are required to accurately inform the clinicians. The purpose of this article was to briefly review radiographic findings of chest diseases in newborns that are relatively common in daily practice.

  5. Update on neonatal hypoglycemia.

    2014-02-01

    Neonatal hypoglycemia is one of the most common biochemical abnormalities encountered in the newborn. However, controversy remains surrounding its definition and management especially in asymptomatic patients. New information has been published that describes the incidence and timing of low glucose concentrations in the groups most at risk for asymptomatic neonatal hypoglycemia. Furthermore, one large prospective study failed to find an association between repetitive low glucose concentrations and poor neurodevelopmental outcomes in preterm infants. But hypoglycemia due to hyperinsulinism, especially genetic causes, continued to be associated with brain injury. New advances were made in the diagnosis and management of hyperinsulinism, including acquired hyperinsulinism in small for gestational age infants and others. Continuous glucose monitoring remains an attractive strategy for future research in this area. The fundamental question of how best to manage asymptomatic newborns with low glucose concentrations remains unanswered. Balancing the risks of overtreating newborns with low glucose concentrations who are undergoing a normal transition following birth against the risks of undertreating those in whom low glucose concentrations are pathological, dangerous, and/or a harbinger of serious metabolic disease remains a challenge.

    Full Text Available Multiple pregnancy is a pregnancy where more than one fetus develops simultaneously in the womb, as a result of the ovulation and fertilization of more than one egg. It is relatively rare in humans and represents the rest of the phylogenetic stages. The most common are twins and they indicate the development of two fetuses in the womb. The frequency of twin pregnancies is about 1%. Multiple pregnancies belong to a group of high-risk pregnancies because of the many complications that occur during the pregnancy: higher number of premature deliveries, bleeding, early neonatal complications and higher perinatal morbidity and mortality. Such pregnancies and infants require greater supervision and monitoring. The aim of this study was to determine the percentage of baby twins born at the maternity ward of the General Hospital in Prokuplje and their morbidity and mortality. Data on the total number of deliveries, number of twins, parity and maternal age, gestational age, body weight of twins, method of delivery, Apgar score and perinatal mortality were collected and statistically analyzed by means of retrospective analysis of operative birth and neonatal protocol for 6 years (2005 of 2010. Out of 4527 mothers who gave birth 43 were pairs of twins, or 0.95% of women gave birth to twins. These babies are more likely born by Caesarean section, but delivered with slightly lower birth weight.

    Neonatal sigmoid volvulus is a rare entity. It is associated with Hirschsprung's disease. Presentation is acute abdominal distention, vomiting and obstipation. Abdominal radiograph will show the "coffee bean" sign, but this is frequently missed and the diagnosis requires a high index of suspicion. Treatment options include contrast enema, colonoscopy or laparotomy, depending on the condition of the baby and local availability. During the last 6years, 6 infants with sigmoid volvulus were treated in our department. Four presented during the first 48h since birth, and 2 presented at the age of 2 and 7weeks of age. One child was operated and 5 had primary contrast enema with radiologic de-volvulus. Rectal biopsy was performed in all cases; three children had Hirschsprung's disease. Those with normal biopsies responded well to rectal washouts. Two patients had early one stage transanal pullthrough and one had 2 further occasions of sigmoid volvulus prior to definitive surgery. All three recovered with an uneventful course. Neonatal sigmoid volvulus requires a high level of suspicion. Contrast enema is efficient for primary de-volvulus. Rectal biopsy should be performed and if positive for Hirschsprung's disease, surgery should be performed sooner rather than later. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Existe un gran ecosistema microbiano en la cavidad oral donde Staphylococcus aureus ( S. aureus se puede encontrar, causando patologías orales tales como quelitis angular, las paperas y la mucositis estafilocócica. Estas enfermedades producidas por S. aureus en la cavidad oral son consecuencia de los factores de virulencia, toxinas y multiresistencia a los antibióticos, lo que contribuye a la infección. La colonización en la cavidad oral por S. aureus en pacientes sanos es de 24% a 36%. Sin embargo, la incidencia aumenta a 48% en pacientes con prótesis debido a la formación de biofilms en la superficie de las dentaduras postizas. Actualmente, no existe ningún tratamiento para infecciones orales sin el uso de antibióticos. Investigaciones recientes indican que las nanopartículas de plata (AgNPs son un material o estrategia para eliminar S. aureus debido a su efecto antibacteriano. Sin embargo, el mecanismo del efecto inhibidor de los iones de Ag sobre S. aureus es sólo parcialmente conocida y muy poco se ha informado. Por lo tanto, el propósito de la presente revisión sistemática es determinar las estrategias y retos de la utilización de biomateriales antimicrobianos con AgNPs frente a las infecciones orales de S. aureus.

    Two major subspecies of Staphylococcus cohnii, namely S. cohnii subsp. cohnii, from humans, and S. cohnii subsp. urealyticum, from humans and other primates, are described on the basis of a study of 14 to 25 strains and 18 to 33 strains, respectively. DNA-DNA hybridization studies conducted in our laboratory in 1983 (W. E. Kloos and J. F. Wolfshohl, Curr. Microbiol. 8:115-121, 1983) demonstrated that strains representing the different subspecies were significantly divergent. S. cohnii subsp. urealyticum can be distinguished from S. cohnii subsp. cohnii on the basis of its greater colony size; pigmentation; positive urease, beta-glucuronidase, and beta-galactosidase activities; delayed alkaline phosphatase activity; ability to produce acid aerobically from alpha-lactose; and fatty acid profile. The type strain of S. cohnii subsp. cohnii is ATCC 29974, the designated type strain of S. cohnii Schleifer and Kloos 1975b, 55. The type strain of S. cohnii subsp. urealyticum is ATCC 49330.

Este microorganismo produce una gran variedad de infecciones incluyendo osteomielitis, endocarditis invasora, artritis séptica y septicemia. La multirresistencia es un factor que influye en la persistencia de los SAMR dentro del ámbito hospitalario. La introducción de técnicas de tipificación molecular dentro de las investigaciones epidemiológicas ha provisto nuevas herramientas para conocer el origen y las vías de diseminación de este microorganismo. Una de las conclusiones importantes que han surgido de este tipo de estudios es que un número pequeño de clonas son las responsables de las infecciones estafilocócicas en todo el mundo.Nosocomial infections due to methicillin-resistant Staphylococcus aureus (MRSA is an important health problem worldwide. This microorganism causes a variety of clinical infections, including osteomyelitis, invasive endocarditis, septic arthritis and septicemia. Antimicrobial resistance is a factor that influences the persistence of MRSA in the hospital environment. The introduction of molecular typing techniques in epidemiological investigations has provided new tools for identifying the microorganism's origin and routes of dissemination. One of the most important conclusions that have resulted from these types of studies is that a small number of clones are responsible for most of the staphylococcal infections throughout the world.

  15. Neonates need tailored drug formulations.

    Allegaert, Karel

    2013-02-08

    Drugs are very strong tools used to improve outcome in neonates. Despite this fact and in contrast to tailored perfusion equipment, incubators or ventilators for neonates, we still commonly use drug formulations initially developed for adults. We would like to make the point that drug formulations given to neonates need to be tailored for this age group. Besides the obvious need to search for active compounds that take the pathophysiology of the newborn into account, this includes the dosage and formulation. The dosage or concentration should facilitate the administration of low amounts and be flexible since clearance is lower in neonates with additional extensive between-individual variability. Formulations need to be tailored for dosage variability in the low ranges and also to the clinical characteristics of neonates. A specific focus of interest during neonatal drug development therefore is a need to quantify and limit excipient exposure based on the available knowledge of their safety or toxicity. Until such tailored vials and formulations become available, compounding practices for drug formulations in neonates should be evaluated to guarantee the correct dosing, product stability and safety.

    Full Text Available PURPOSE: To study the microbial agents, chiefly Chlamydia trachomatis and other bacteria, in neonatal conjunctivitis. METHODS: Conjunctival specimens from 70 newborns with conjunctivitis were subjected to bacterial culture and sensitivity testing, monoclonal antibody based C. trachomatis antigen detection test and species-specific Chlamydia antibody detection in the sera of babies and their mothers, by micro-immunofluorescence assay. RESULTS: Bacteria were isolated from 35 (50% babies; the majority (20, 57.14% were Staphylococcus epidermidis. C. trachomatis antigen was detected in conjunctival smears of 17 (24% babies, and 6 (35.29% of them were positive for other bacteria. Six babies and their mothers tested positive for C. trachomatis Ig G antibodies. At follow-up after 14 weeks, 6 (35.29% of the Chlamydia antigen-positive babies were found to have developed recurrent conjunctivitis. CONCLUSION: C. trachomatis is responsible for almost a quarter of all cases of neonatal conjunctivitis, with recurrences in 35% of cases. Bacteria could be isolated from 50% of the patients though the exact role of Staphylococcus epidermidis, isolated from 28.65% of the neonatal conjunctivitis cases, remains unclear.

    Full text: Hypoxic-Ischemic insults in the brain of neonates constitute major cause of morbidity and mortality. A wide range of motor, sensory, and cognitive disabilities are observed in this population spanning from slight motor deficits, school difficulties and behavioral problems up to cerebral palsy and mental retardation. Pathologically involved areas characterized by high metabolic demands and therefore with enhanced vulnerability to any reduction or cessation of energy and oxygen supply. Watershed areas of the brain (vascular end zones and vascular border zones) are predominately affected in any adverse event. Radiologic and pathologic appearance of these lesions depends both on the severity of the insult and the maturity of the brain. The dominant pathology observed in preterm neonates is white matter lesions. There are three basic patterns of brain destruction in this population. Periventricular leukomalacia (PVL focal fPVL, diffuse dPVL), germinal matrix haemorrhage (GMH) associated with intraventricular haemorrhage (IVH), and parenchymal haemorrhage (PH). fPVL is characterized by focal necrosis of all cellular elements in the periventricular white matter, resulting in the formation of cysts, and dPVL is characterized by diffuse destruction of the premyelinating oligodendrocytes (pre-OLs) the precursors of mature oligodendroglia cells responsible for the formation of myelin in a later stage. GMH is located beneath germinal matrix layer surrounding the lateral ventricles and can extend into the ventricular system resulting thus to IVH. Finally, PH is located within the parenchyma adjacent to the ventricles and is believed to represent haemorrhagic infarcts following venous drainage compromise. In term or near-term neonates, the top-ographic pattern of injuries involves mainly gray matter structures. Most frequent predilection sites include the cerebral cortex (paracentral lobule, Rolandic area, visual cortex and hippocampus), basal ganglia, thalamus, and

    The association between pediatric cancer and congenital abnormalities is well known but, there is no exclusive data on the neonatal period and the underlying etiopathogenic mechanisms are unknown. First, to analyze the frequency of neonatal tumours associated with congenital abnormalities; and second, to comment on the likely etiopathogenic hypotheses of a relationship between neonatal tumours and congenital abnormalities. Historical series of neonatal tumours from La Fe University Children's Hospital in Valencia (Spain), from January 1990 to December 1999. Histological varieties of neonatal tumours and associated congenital abnormalities were described. A systematic review of the last 25 years was carried out using Medline, Cancerlit, Index Citation Science and Embase. The search profile used was the combination of "neonatal/congenital-tumors/cancer/neoplasms" and "congenital malformations/birth defects". 72 neonatal tumours were identified (2.8% of all pediatric cancers diagnosed in our hospital) and in 15 cases (20.8%) there was some associated malformation, disease or syndrome. The association between congenital abnormalities and neonatal tumours were: a) angiomas in three patients: two patients with congenital heart disease with a choanal stenosis, laryngomalacia; b) neuroblastomas in two patients: horseshoe kidney with vertebral anomalies and other with congenital heart disease; c) teratomas in two patients: one with cleft palate with vertebral anomalies and other with metatarsal varus; d) one tumour of the central nervous system with Bochdaleck hernia; e) heart tumours in four patients with tuberous sclerosis; f) acute leukaemia in one patient with Down syndrome and congenital heart disease; g) kidney tumour in one case with triventricular hydrocephaly, and h) adrenocortical tumour: hemihypertrophy.

    Abdominal surgery in foals under 30 days old has become more common with improved neonatal care. Early recognition of a foal at risk and better nursing care have increased the survival rates of foals that require neonatal care. The success of improved neonatal care also has increased the need for accurate diagnosis and treatment of gastrointestinal, umbilical, and bladder disorders in these foals. This chapter focuses on the early and accurate diagnosis of specific disorders that require abdominal exploratory surgery and the specific treatment considerations and prognosis for these disorders.

    2005-06-01

    Full Text Available Coagulase-negative staphylococci (CNS, components of the normal flora of neonates, have emerged as important opportunistic pathogens of nosocomial infections that occur in neonatal intensive care units. Some authors have reported the ability of some CNS strains, particularly Staphylococcus epidermidis, to produce a toxin similar to S. aureus delta toxin. This toxin is an exoprotein that has a detergent action on the membranes of various cell types resulting in rapid cell lysis. The objectives of the present study were to standardize the Polymerase Chain Reaction (PCR technique for the detection of the gene responsible for the production of delta toxin (hld gene in staphylococcal species isolated from catheters and blood cultures obtained from neonates, and to compare the results to those obtained with the phenotypic synergistic hemolysis method. Detection of delta toxin by the phenotypic and genotypic method yielded similar results for the S. aureus isolates. However, in S. epidermidis, a higher positivity was observed for PCR (97.4% compared to the synergistic hemolysis method (86.8%. Among CNS, S. epidermidis was the most frequent isolate and was a delta toxin producer. Staphylococcus simulans and S. warneri tested positive by the phenotypic method, but their positivity was not confirmed by PCR for the hld gene detection. These results indicate that different genes might be responsible for the production of this toxin in different CNS species, requiring highly specific primers for their detection. PCR was found to be a rapid and reliable method for the detection of the hld gene in S. aureus and S. epidermidis.

    Perinatal infection may potentiate brain injury among children born preterm. The objective of this study was to examine whether maternal and/or neonatal infection are associated with adverse outcomes among term neonates with encephalopathy. This study is a cohort study of 258 term newborns with encephalopathy whose clinical records were examined for signs of maternal infection (chorioamnionitis) and infant infection (sepsis). Multivariate regression was used to assess associations between infection, pattern, and severity of injury on neonatal magnetic resonance imaging, as well as neurodevelopment at 30 mo (neuromotor examination, or Bayley Scales of Infant Development, second edition mental development index encephalopathy, chorioamnionitis was associated with a lower risk of brain injury and adverse outcomes, whereas signs of neonatal sepsis carried an elevated risk. The etiology of encephalopathy and timing of infection and its associated inflammatory response may influence whether infection potentiates or mitigates injury in term newborns.

    Full Text Available Introduction. Blood stream infection (BSI is a common problem of newborn in neonatal intensive care units (NICUs. Monitoring neonatal infections is increasingly regarded as an important contributor to safe and high-quality healthcare. It results in high mortality rate and serious complications. So, our aim was to determine the incidence and the pattern of BSIs in the NICU of Suez Canal University Hospital, Egypt, and to determine its impact on hospitalization, mortality, and morbidity. Methods. This study was a prospective one in which all neonates admitted to the NICUs in Suez Canal University hospital between January, 2013 and June 2013 were enrolled. Blood stream infections were monitored prospectively. The health care associated infection rate, mortality rate, causative organism, and risk factors were studied. Results. A total of 317 neonates were admitted to the NICU with a mortality rate of 36.0%. During this study period, 115/317 (36.3% developed clinical signs of sepsis and were confirmed as BSIs by blood culture in only 90 neonates with 97 isolates. The total mean length of stay was significantly longer among infected than noninfected neonates (34.5 ± 18.3 and 10.8 ± 9.9 days, resp., P value < 0.001. The overall mortality rates among infected and noninfected neonates were 38.9% and 34.8%, respectively, with a significant difference. Klebsiella spp. were the most common pathogen (27.8% followed by Pseudomonas (21.6% and Staphylococcus aureus (15.4%. Conclusion. The rate of BSIs in NICU at Suez Canal University Hospital was relatively high with high mortality rate (36.0%.

    Introduction The purpose of the study was to describe demographic and clinical characteristics and outbreak handling of a large methicillin-resistant Staphylococcus aureus (MRSA) outbreak in a neonatal intensive care unit (NICU) in Denmark June 25th–August 8th 2008, and to identify risk factors for MRSA transmission. Methods Data were collected retrospectively from medical records and the Danish Neobase database. All MRSA isolates obtained from neonates, relatives and NICU health care workers (HCW) as well as environmental cultures were typed. Results During the 46 day outbreak period, 102 neonates were admitted to the two neonatal wards. Ninety-nine neonates were subsequently sampled, and 32 neonates (32%) from 25 families were colonized with MRSA (spa-type t127, SCCmec V, PVL negative). Thirteen family members from 11 of those families (44%) and two of 161 HCWs (1%) were colonized with the same MRSA. No one was infected. Five environmental cultures were MRSA positive.

    Full Text Available INTRODUCTION: The purpose of the study was to describe demographic and clinical characteristics and outbreak handling of a large methicillin-resistant Staphylococcus aureus (MRSA outbreak in a neonatal intensive care unit (NICU in Denmark June 25(th-August 8(th 2008, and to identify risk factors for MRSA transmission. METHODS: Data were collected retrospectively from medical records and the Danish Neobase database. All MRSA isolates obtained from neonates, relatives and NICU health care workers (HCW as well as environmental cultures were typed. RESULTS: During the 46 day outbreak period, 102 neonates were admitted to the two neonatal wards. Ninety-nine neonates were subsequently sampled, and 32 neonates (32% from 25 families were colonized with MRSA (spa-type t127, SCCmec V, PVL negative. Thirteen family members from 11 of those families (44% and two of 161 HCWs (1% were colonized with the same MRSA. No one was infected. Five environmental cultures were MRSA positive. In a multiple logistic regression analysis, nasal Continuous Positive Airway Pressure (nCPAP treatment (p = 0.006 and Caesarean section (p = 0.016 were independent risk factors for MRSA acquisition, whereas days of exposure to MRSA was a risk factors in the unadjusted analysis (p = 0.04. CONCLUSIONS: MRSA transmission occurs with high frequency in the NICU during hospitalization with unidentified MRSA neonates. Caesarean section and nCPAP treatment were identified as risk factors for MRSA colonization. The MRSA outbreak was controlled through infection control procedures.

    Respiratory distress is a very common and yet non-specific symptom in neonates and young infants. It may be manifested clinically in many ways, including tachypnea, apnea, periodic respiratory, grunting, retractions, nasal flaring, and cyanosis. In many instances, the chest radiograph is diagnostic or at least suggestive of the diagnosis. This fact is important in determining surgical or medical conditions that require emergency therapy. Even if the chest film is normal, valuable information can be gained. This initial normal radiograph can be used as a baseline film in the face of further developing symptoms which, likewise, may have developing radiographic findings. In any event, the chest radiograph gives the clinician ''direction'' in his or her search for the cause of the patient's respiratory distress

    Full Text Available Idiopathic pulmonary hemosiderosis (IPH is a rare complex entity characterized clinically by acute or recurrent episodes of hemoptysis secondary to diffuse alveolar hemorrhage. The radiographic features are variable, including diffuse alveolar-type infiltrates, and interstitial reticular and micronodular patterns. We describe a 3-week-old infant presenting with hemoptysis and moderate respiratory distress. Idiopathic pulmonary hemosiderosis was the first working diagnosis at the Emergency Department and was confirmed, 2 weeks later, by histological studies (bronchoalveolar lavage. The immunosuppressive therapy by 1 mg/kg/d prednisone was immediately started, the baby returned home on steroid therapy at a dose of 0,5 mg/kg/d. The diagnosis of idiopathic pulmonary hemosiderosis should be evocated at any age, even in the neonate, when the clinical presentation (hemoptysis and abnormal radiological chest images is strongly suggestive.

    Although largely deprived from exogenous stimuli in utero, the mucosal barriers of the neonate after birth are bombarded by environmental, nutritional, and microbial exposures. The microbiome is established concurrently with the developing immune system. The nature and timing of discrete interactions between these two factors underpins the long-term immune characteristics of these organs, and can set an individual on a trajectory towards or away from disease. Microbial exposures in the gastrointestinal and respiratory tracts are some of the key determinants of the overall immune tone at these mucosal barriers and represent a leading target for future intervention strategies. In this review, we discuss immune maturation in the gut and lung and how microbes have a central role in this process.

    Kinship, understood as biogenetic proximity, between a chosen animal model and a human patient counterpart, is considered essential to the process of ‘translating’ research from the experimental animal laboratory to the human clinic. In the Danish research centre, NEOMUNE, premature piglets are fed...... a novel milk diet (bovine colostrum) to model the effects of this new diet in premature infants. Our ethnographic fieldwork in an experimental pig laboratory and a neonatal intensive care unit (NICU) in 2013–2014 shows that regardless of biogenetics, daily practices of feeding, housing, and clinical care...... the researchers refer to as the ‘translatability’ of the results. In the NICU, parents of premature infants likewise imagine a kind of interspecies kinship when presented with the option to supplement mother's own milk with bovine colostrum for the first weeks after birth. However, in this setting the NICU...

    Technological advances have caused a decrease in the number of infant deaths. Pre-term infants now have a substantially increased chance of survival. One of the mechanisms that is vital to saving the lives of these infants is continuous monitoring and early diagnosis. With continuous monitoring huge amounts of data are collected with so much information embedded in them. By using statistical analysis this information can be extracted and used to aid diagnosis and to understand development. In this study we have a large dataset containing over 180 pre-term infants whose heart rates were recorded over the length of their stay in the Neonatal Intensive Care Unit (NICU). We test two types of models, empirical bayesian and autoregressive moving average. We then attempt to predict future values. The autoregressive moving average model showed better results but required more computation.

    A pre-term baby girl was born following a pregnancy complicated by severe polyhydramnios at a gestational age of 36 weeks. She was initially suffering from respiratory distress consistent with idiopathic respiratory distress syndrome, and altered electrolyte imbalance with hyponatremia, hypokalemia and hypochloremic metabolic alkalosis. However, during the third week of life when she had dehydration along with significant electrolyte imbalance, Bartter's syndrome was considered which was supported by findings of high renin and aldosterone levels. Treatment was done by correction of electrolytes and dehydration along with indomethacin. The drug was well tolerated. The infant showed correction of electrolyte imbalance. The features of this case suggest an extreme form of Bartter's syndrome presenting from the early days of life. The syndrome is reported because of it's rarity and alerts pediatricians to the antenatal and neonatal variant of Bartter's syndrome. (author)

    The future of neonatal informatics will be driven by the availability of increasingly vast amounts of clinical and genetic data. The field of translational bioinformatics is concerned with linking and learning from these data and applying new findings to clinical care to transform the data into proactive, predictive, preventive, and participatory health. As a result of advances in translational informatics, the care of neonates will become more data driven, evidence based, and personalized. PMID:22924023

    Neonatal breast hypertrophy is a common phenomenon in term infants, superadded infection can lead to mastitis and that can progress to breast abscess with short and long term detrimental effects. Our effort is to study the prevalence, risk factors, the current microbial profile and sensitivity pattern in these infections in order to suggest an optimal treatment plan for these patients. Case series. Hospital based study conducted in Kashmir on the native population. 2011 to 2013. 32 neonates with features of mastitis or abscess were included in the study. Demographic and clinical data, laboratory work-up were recorded for all these patients in a patient form. Gram stain of the purulent nipple discharge or pus obtained on drainage was done and the specimens were culture plated. Antibiotic sensitivity was determined by disk diffusion and categorized by current Clinical and Laboratory Standards Institute (CLSI) guidelines. Most babies were full term, the age range was 6-48 days. Peak incidence for mastitis was in the 2nd week and for abscess in the 4th week. The ratio of male: female was 1:2 in the entire group, there was greater preponderance of female involvement with increasing age. Massage for expression of secretions a common practice in the study population had been done in 15 patients, especially in male babies. The babies were generally well and associated skin pustulosis was common. Laboratory workup showed polymorphonuclear leucocytosis and CRP positivity. Gram staining showed gram positive cocci in 13 patients and gram negative rods in 1 patient. Culture revealed Staphylococcus aureus in 18, E.col in 2, klebsiella in 1 patient and was sterile in 2 patients. Most strains of Staphylococcus aureus were resistant to macrolides and penicillins. Fifteen were methicillin sensitive and 3 were resistant but were sensitive to amikacin, ofloxacin and vancomycin. Gram negative rods were sensitive to, aminoglycosides, chloramphenicol, quinolones, piperacillin

    Our aims were to determine the incidence of bacteraemia in a cohort of neonatal patients over a 14 year period, to describe the organisms involved, and to establish the rates of sepsis with regard to both early onset sepsis (EOS) and late onset sepsis (LOS). Lastly, we investigated the trends of neonatal sepsis, to determine whether changes in clinical practice influenced the rate of blood culture positivity. With regards to EOS, GBS was the predominant pathogen, followed by E.coli, CoNS, and S. aureus . The overall mean EO rate per 1000 live births (LBs) was 1.19. Looking at LOS, S. aureus , CoNS , Enterococcus spp. were the most common bacteria cultured. The mean LOS rate was 1.88 per 1000 live births. The overall rate of EOS remained fairly steady. GBS remains the major pathogen in EOS; however its incidence has remained largely unchanged over time in relation to both EOS and LOS. Conversely the rate of LOS peaked from ’05-’09, mainly due to an increase in Staphylococcus aureus , CoNS and Enterococcus spp. cases, and then improved dramatically in the following years. This was likely due to a change in hospital policies in relation to hand hygiene and intravenous line placement and maintenance.

    Neonatal suppurative parotitis is a rare condition characterized by swelling, pain, and erythema over the affected gland. Antimicrobials and adequate hydration are an essential part of treatment. Surgical intervention is reserved for organized abscesses and for infections not responding to medical management. A case report and review of the literature. Only few case reports and case series are reported in literature on neonatal parotitis. Transmission of bacteria seems to occur mainly by ascending spread through Stensen's duct, or by hematogenous spread from a distant focus. Dehydration, low birth weight, immune suppression, ductal obstruction, oral trauma and structural abnormalities of the parotid gland are recognised as risk factors. The most common pathogen is Staphylococcus aureus. Other less frequent agents are other Gram-positive cocci, Gram-negative bacilli and rarely anaerobic bacteria. Advances in antimicrobial therapy have improved both outcome and prognosis. Thanks to the prompt antibiotic treatment complications are now drastically reduced. Ultrasound examination may help in the diagnosis and monitoring of clinical course. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    2017-06-01

    Aerobic vaginitis (AV) is an endogenous opportunistic infection brought about by the disruption of the normal vaginal microbiota. Its early diagnosis and treatment during pregnancy may reduce the risk of negative pregnancy outcomes. The aim of this review was to report on the aerobic bacteria most prevalent in AV and to provide evidence of the threat of untreated AV on pregnancy outcomes. More than 300 papers on preterm delivery were extracted from several research domains and filtered to include only AV-associated bacteria such as Staphylococcus aureus, Enterococcus faecalis, Escherichia coli and Group B streptococci and their association with adverse pregnancy outcomes. Due to the diverse sample groups, study techniques and outcomes, a meta-analysis was not conducted. The review revealed that the association of AV with adverse pregnancy outcomes has not been as widely researched as bacterial vaginosis (BV) and needs further investigation. Furthermore, the frequent misdiagnosis of AV coupled with the emerging antimicrobial resistance associated with bacteria implicated in AV and neonatal nosocomial infections pose a problem for prophylaxis and treatment to reduce the risk of maternal and neonatal morbidity and mortality.

    Objective: To study the patterns of causative bacteria and antibiotic resistance in neonatal sepsis. Results: Among 228 cases included in the study, the male to female ratio was 2.1 to 1. The gestational age was less than 36 weeks in 68 (30%) cases and low birth weight babies were 143 (62.6%). History of birth asphyxia was present in 103 (45%) cases. There were 142 (62.3%) cases of early onset ( 7 days). Out of 233 positive blood cultures Escherichia coli was found to be commonest (47.8%, n =111, p<0.05) both in early onset (47.8%, n=68, p <0.05) and late onset sepsis (47.3%,n=43, p<0.05). Staphylococcus aureus was the most common among gram positive organism. Resistance to cefotaxime, ceftazidime and amikacin was 34% to 80% and to ciprofloxacin 13% to 72%. A total of 64 cases (28%) died. Mortality was four times higher in early onset sespis. Conclusion: Gram negative bacteria are the commenst cause of neonatal sepsis. The resistance to the commonly used antibiotics is alarmingly high. Mortality is four times higher in early one set sepsis. (author)

    Serum concentrations, urinary excretion and clinical responses of flomoxef (FMOX) were studied. The results are summarized as follows. 1. Serum concentrations of FMOX were 17.4 micrograms/ml 1-hour after intravenous injection on the average in 5 cases who received approximately 10 mg/kg, 41.8 micrograms/ml in 2 cases given 20 mg/kg, and 69.6 micrograms/ml in 2 cases given 40 mg/kg, indicating that serum concentrations of FMOX changed in a dose-dependent manner in this range. Average serum half-life (T 1/2) in 4 mature babies was 2.48 hours and that in 6 premature babies was 3.17 hours, indicating that elimination rates in premature cases tend to be slower than those in mature cases. Urinary recovery rates averaged 39.2% in the first 6 hours in 5 cases examined. 2. Five newborns or premature babies received FMOX 33.1-80.2 mg/kg (b.i.d. or t.i.d.) via intravenous route for 5 to 8 days. FMOX showed excellent or good clinical effectiveness in the treatment of all patients including 1 case each of sepsis with urinary infection, furunclal otitis, impetigo, uterogenic fetus infection and urinary infection. Bacteriological responses were also studied, and eradication of identified organisms (Escherichia coli 3 strains and Staphylococcus aureus 2 strains) was obtained upon the FMOX treatment, but in 1 strain of S. aureus showed only a decrease. No adverse reactions were observed in any cases, but a slight elevation of eosinophil was noted in 1 patient receiving a dose of 210 mg a day. From the results obtained in these tests, FMOX appears to be very usefull and safe for the treatment of some infectious diseases in neonates.

    The evolution of Staphylococcus aureus during the modern antibiotic era has been delineated by distinct strain emergence events, many of which include acquisition of antibiotic resistance. The relative high burden of methicillin-resistant S. aureus (MRSA) in healthcare and community settings is a major concern worldwide. Vancomycin, a glycopeptide antibiotic that inhibits cell wall biosynthesis, remains a drug of choice for treatment of severe MRSA infections. S. aureus strains exhibiting increased resistance to vancomycin, known as vancomycin intermediate-resistant S. aureus (VISA) (MIC = 4-8 µg/mL), were discovered in the 1990s. The molecular basis of resistance in VISA is polygenic and involves stepwise mutations in genes encoding molecules predominantly involved in cell envelope biosynthesis. S. aureus isolates with complete resistance to vancomycin (MIC ≥ 16 µg/mL) are termed vancomycin-resistant S. aureus (VRSA)—they were first reported in the U.S. in 2002. Resistance in VRSA is conferred by the vanA gene and operon, which is present on a plasmid. Although treatment of VRSA infections is challenging, the total number of human VRSA infections to date is limited (14 in the U.S.). By comparison, the burden of VISA is relatively high and the molecular mechanisms of resistance are less well-defined. VISA are associated with persistent infections, vancomycin treatment failure, and poor clinical outcomes. Here, we review in brief progress made toward understanding the acquisition of antibiotic resistance in S. aureus, with an emphasis on the molecular mechanisms underlying vancomycin resistance.

    The following case study reports three cases of neonatal bacterial parotiditis observed over a period of seven months. Diagnosis is often based on patient's clinical features: they typically include hyperthermia, swelling, erythema, warmth as well as local tenderness and purulent discharge at Stensen duct during the massage of the parotid. The clinical diagnosis is confirmed by ultrasound and by culture of parotid purulent secretion. They are mainly of nosocomial origin and are generally caused by prematurity and dehydration. Early treatment improves patient outcome. Risk factors such as age should lead clinicians to start empiric antibiotic therapy first and then antibiotic therapy based on direct examination of pus extracted from Stensen duct. Staphylococcus aureus, Streptococcus Viridans and anaerobic germs are most commonly isolated. Acute parotiditis are extremely rare in the neonatal period: less than 50 cases have been reported in the literature. We here report three rather peculiar cases. The diagnosis was suspected on the basis of signs of local inflammation.

    Full Text Available Neonatal tetanus (NNT has been secondary in the whole world in the death list of diseases which can be protected by the help of vaccine. It’s an important community health problem in the less-developed countries in which pre-birth care services are limited, assisting a mother at childbirth by uneducated people in dirty atmosphere and the immunity against tetanus is not enough. Studies have shown that minor part of the cases have been expressed in most of the countries. Because of that NNT have been called as “silent/invisible murderer”. In Turkey, in the year of 2003 it has been seen 15 cases, and 12 of them have been resulted in death. The methods which will be applied to carry out the elimination of NNT are; the vaccination of pregnant women with at least two doses tetanus toxoid and providing clean birth conditions for all of the pregnant women. However, in Turkey the proportion of the women who have two doses of tetanus vaccine is 41%. To eliminate NNT in our country, all the pregnant women must be attained, the ones who are attained must be presented with qualified pre-birth care service which also includes tetanus immunity and the births must be carried out under healty conditions. As smallpox and polio eradication, NNT elimination will also be accomplished by self-sacrificing works of personnel in primary health care. [TAF Prev Med Bull 2006; 5(3.000: 229-233

    In a retrospective multi-center study, we investigated eighteen infants with unilateral cerebral infarctions confirmed by computed tomography (CT) scans. The initial symptoms were observed in all the patients between 0 and 3 days of age. Convulsions or apneic attacks were the initial symptoms in all but one. Only 4 patients had complicated obstetric histories and none showed polycythemia or electrolyte abnormalities. All of the initial CT scans revealed unilaterally localized hypodense areas. In 10, the initial CT scans were performed within 24 hours after the clinical onset. In 16, the lesions were within the territory of the middle cerebral artery, 9 of which also involved the cortico-spinal tract (CST). In the remaining 2 patients, the lesions were located whithin the territory of the posterior cerebral artery. None of the 9 patients without CST involvement developed hemiplegia, whereas 5 (56%) of the 9 with CST involvement had hemiplegia, which is a fairly low incidence compared with that in adult cases. This difference was thought to be related to neonatal brain plasticity. (author)

  3. Neonatal aortic stenosis.

    2005-09-01

    Neonatal aortic stenosis is a complex and heterogeneous condition, defined as left ventricular outflow tract obstruction at valvular level, presenting and often requiring treatment in the first month of life. Initial presentation may be catastrophic, necessitating hemodynamic, respiratory and metabolic resuscitation. Subsequent management is focused on maintaining systemic blood flow, either via a univentricular Norwood palliation or a biventricular route, in which the effective aortic valve area is increased by balloon dilation or surgical valvotomy. In infants with aortic annular hypoplasia but adequately sized left ventricle, the Ross-Konno procedure is also an attractive option. Outcomes after biventricular management have improved in recent years as a consequence of better patient selection, perioperative management and advances in catheter technology. Exciting new developments are likely to significantly modify the natural history of this disorder, including fetal intervention for the salvage of the hypoplastic left ventricle; 3D echocardiography providing better definition of valve morphology and aiding patient selection for a surgical or catheter-based intervention; and new transcutaneous approaches, such as duel beam echo, to perforate the valve.

    A fatally ending index case of sepsis osteoarthritis that was diagnosed retrospectively initiated this report. This patient had severe, asymmetrically distributed metaphyseal growthdisturbances, many long bones. In order to determine the features of early radiologic diagnosis we report the findings of 7 further patients with neonatal septic osteoarthritis with clinical and radiological follow-up. The most important observation for early radiologic diagnosis of osteoarthritis is the displacement of fat layers along the metaphysis. Other findings of the soft tissues have the same diagnostic value as bone destruction and subperiosteal new bone formation found one to three weeks later on roentgenfilms. Detecting early signs of osteoarthritis helps in localizing the focus for bacteriologic diagnosis, which is to be more successful than blood cultures. Diagnosing a joint empyema initiates surgical intervention for pressure relief in order to avoid necrosis of the epiphysis as seen in the femoral bone in septic arthritis of the hip joint. Early diagnosis and treatment to destruction of growing cartilage is necessary to avoid gross disturbances and length discrepancies of long bones. In cases of sepsis called 'babygram' and a repeat examination 10 to 14 days later is mandatory. (orig.) [de

    Full Text Available This study has in view to establish and test the sensitivity of Staphylococcus aureus antibiotics. There are different injuries caused by superficial skin infections: from simple pimples to infections that endanger our lives, like an abscess, furuncle septicemia, meningitis, toxic food, urinary tract infection at sexually active young women. Samples have been taken from 30 people with staphylococcus infections. They were nineteen women and eleven men, between the age of 2 and 79. During this study some antibiograms have been made, based on pharyngeal exudates, acne secretion and urine culture. It has been established that the most efficient recommended antibiotics are: oxacilin, erythromycin, rifampicin and ciprofloxacin. The penicillin turned out to be less efficient to remove and destroy the Staphylococcus aureus species.

    Objective:To compare the in vitro antimicrobial efficacy of ceftaroline with linezolid against Staphylococcus aureus and methicillin resistant Staphylococcus aureus. Study Design: Quasi-experimental study. Place and Duration of Study: Microbiology Department, Army Medical College, Rawalpindi, from January to December 2013. Methodology: Clinical samples from respiratory tract, blood, pus and various catheter tips routinely received in the Department of Microbiology, Army Medical College, Rawalpindi were innoculated on blood and MacConkey agar. Staphylococcus aureus was identified by colony morphology, Gram reaction, catalase test and coagulase test. Methicillin resistant Staphylococcus aureus detection was done by modified Kirby Bauer disc diffusion method using cefoxitin disc (30g) and the isolates were considered methicillin resistant if the zone of inhibition around cefoxitin disc was /sup 2/ 21 mm. Bacterial suspensions of 56 Staphylococcus aureus isolates and 50 MRSA isolates were prepared, which were standardized equal to 0.5 McFarland's turbidity standard and inoculated on Mueller-Hinton agar plates followed by application of ceftaroline and linezolid disc (Oxoid, UK), according to manufacturer's instructions. The plates were then incubated at 37 Degree C aerobically for 18 - 24 hours. Diameters of inhibition zone were measured and interpretated as per Clinical and Laboratory Standards Institute (CLSI) guidelines. Results: Out of 106 isolates all of the 56 Staphylococcus aureus (100%) were sensitive to ceftaroline and linezolid. However, out of 50 methicillin resistant Staphylococcus aureus, 48 (96%) were sensitive to ceftaroline whereas, 49 (98%) were sensitive to linezolid. Conclusion: Ceftaroline is equally effective as linezolid against Staphylococcus aureus and methicillin resistant Staphylococcus aureus. (author)

    A male term neonate, at day 23 of life, presented with vesicular lesions over the trunk, which spread to allover the body on the next day. Five days later, he started developing blistering of the skin over the trunk and extremities, which subsequently ruptured, leaving erythematous, tender raw areas with peeling of the skin. The mother had vesicular eruptions, which started on the second day of delivery and progressed over the next 3 days. Subsequently, similar eruptions were noticed in two of the siblings before affecting the neonate. On the basis of the exposure history and clinical picture, a diagnosis was made of varicella infection with staphylococcal scalded skin syndrome (SSSS). The blood culture and the wound surface culture grew Staphylococcus aureus. Treatment included intravenous fluid, antibiotics, acyclovir and wound care. However, after 72 h of hospitalisation, the neonate first developed shock, refractory to fluid boluses, vasopressors and catecholamine along with other supports; and he then succumbed. In all neonates, staphylococcal infection with varicella can be fatal due to SSSS, the toxic shock syndrome or septicaemia.

    Full Text Available BACKGROUND : Neonates receiving phototherapy have side effects like hypocalcemia and electrolyte changes. Our study is hereby intended to study the serum sodium changes due to phototherapy. AIMS : To evaluate the serum sodium changes in neonates receiving phototherapy f or neonatal hyperbilirubinemia. SETTINGS AND DESIGN : A prospective hospital based comparative study conducted on neonates admitted in the Neonatal Intensive Care Unit receiving phototherapy. METHODS AND MATERIAL : A predesigned proforma has aided the enroll ment of 252 newborns into the study. Serum bilirubin and serum sodium were determined before and after termination of phototherapy. The first samples were considered as controls. A comparative study was made between before and after phototherapy groups to determine the incidence of serum sodium imbalances. STATISTICAL ANALYSIS USED : Proportions will be compared using chi - square test. All data of various groups will be tabulated and statistically analyzed using suitable statistical tests (Student's t test. RESULTS : Male to Female ratio was 1.45 : 1. Incidence of low birth weight babies was 23% and preterm was 20.2%. Mean birth weight and gestational age was 2.84±0.51 kg and 38.44±1.98 wks respectively. Mean duration of phototherapy was 37.65±11.06 hrs. The incidence of hyponatremia post phototherapy found to be 6% which was more in low birth weight (LBW babies (17.2% , p48 hrs (p<0.001. Even the decline in mean serum sodium values after phototherapy found to be statistically significant. CONCLUSION : Our study shows that neonates u nder phototherapy are at higher risk of hyponatremia. This risk is greater in premature and LBW babies and hence this group of babies should be closely monitored for changes in serum sodium and should be managed accordingly.

    Thyroid hormone determination (T4, T3, rT3, TSH) in cord blood of 3,897 newborns was carried out in Metro Manila (non-endemic) and central, Northern and Southern Luzon (endemic for goiter). The objective is to detect congenital hypothyroidism and establish its incidence in new born Filipinos. This was done by radioimmunoassay, using commercial kits from Abbott Laboratories. The results obtained as mean values for non-endemic regions are: T4: 10.96 +- 2.25 ug/dl; T3: 60-64 +- 13.82 ng/dl; rT3: 250.4 +- 64.9 ng/dl; and TSH 5.89 +- 2.58 uU/ml, n=200. Mean values in endemic regions (n = 205) are T4: 9.46 +- 2.18 ug/dl; T3: 67.8 +- 12.05 ng/dl; rT3: 184.3 +- 32.7 ng/dl and TSH: 6.65 +- 3.13 uU/ml. From the above data, nomograms were drawn where the values obtained from each case were plotted. From non-endemic regions 28 positive cases were recalled and in the endemic regions 16 positive cases were also recalled for re-examination but most of them turned out to be false positive. As of now, four positive cases were found in Metro Manila, i.e. 4/2, 441 births and five in endemic regions out of 1,456 births so the incidence of neonatal hypothyroidism is 9/3,897 births. This is 9 times higher than most reports abroad which is about 1/4000 births. (Auth.). 36 refs; 10 tabs; 10 figs

  14. Fetal and neonatal thyrotoxicosis

    Batra, Chandar Mohan

    2013-01-01

    Fetal thyrotoxicosis is a rare disease occurring in 1 out of 70 pregnancies with Grave's disease or in 1 out of 4000-50,000 deliveries. The mortality is 12-20%, usually from heart failure, but other complications are tracheal compression, infections and thrombocytopenia. It results from transfer of thyroid stimulating immunoglobulins from mother to fetus through the placenta. This transplacental transfer begins around 20th week of pregnancy and reaches its maximum by 30th week. These autoantibodies bind to the fetal thyroid stimulating hormone (TSH) receptors and increase the secretion of the thyroid hormones. The mother has an active autoimmune thyroid disease or has been treated for it in the past. She may be absolutely euthyroid due to past treatment by drugs, surgery or radioiodine ablation, but still have active TSH receptor stimulating autoantibodies, which can cause fetal thyrotoxicosis. The other features of this disease are fetal tachycardia, fetal goiter and history of spontaneous abortions and findings of goiter, ascites, craniosyntosis, fetal growth retardation, maceration and hydrops at fetal autopsy. If untreated, this disease can result in intrauterine death. The treatment for this disease consists of giving carbimazole to the mother, which is transferred through the placenta to the fetus. The dose of carbimazole is titrated with the fetal heart rate. If the mother becomes hypothyroid due to carbimazole, thyroxine is added taking advantage of the fact that very little of thyroxine is transferred across the placenta. Neonatal thyrotoxicosis patients are very sick and require emergency treatment. The goal of the treatment is to normalize thyroid functions as quickly as possible, to avoid iatrogenic hypothyroidism while providing management and supportive therapy for the infant's specific signs and symptoms.

    Antibiotic resistance is a worldwide problem. We describe 25 years of responsible antibiotic use in a tertiary neonatal unit. Data on neonatal infections and antibiotic use were collected prospectively from 1990 to 2014 at a single tertiary Sydney neonatal intensive care unit attached to a maternity unit. There are approximately 5500 deliveries and 900 nursery admissions per year. The mean annual rate of late-onset sepsis was 1.64 episodes per 100 admissions. The mean number of late-onset sepsis episodes per admission to the neonatal unit decreased by 4.0% per year (95% CI 2.6% to 5.4%; p<0.0001) and occurred particularly in infants born weighing <1500 g. No infants with negative cultures relapsed with sepsis when antibiotics were stopped after 48-72 hours. Antibiotic use decreased with time. The proportion of colonising methicillin-resistant Staphylococcus aureus isolates decreased by 7.4% per year (95% CI 0.2% to 14.1%; p=0.043). The proportion of colonising Gram-negative bacilli isolates resistant to either third-generation cephalosporins or gentamicin increased by 2.9% per year (95% CI 1.0% to 4.9%; p=0.0035). Most were cephalosporin-resistant; gentamicin resistance was rare. An average of one baby per year died from late-onset sepsis, the rate not varying significantly over time. The mortality from episodes of late-onset sepsis was 25 of 332 (7.5%). Stopping antibiotics after 2-3 days if neonatal systemic cultures are negative is safe. However, it does not prevent the emergence of cephalosporin-resistant Gram-negative organisms. Published by the BMJ Publishing Group Limited.

Hydrocolpos is cystic dilatation of the vagina with fluid accumulation due to a combination of stimulation of secretary glands of the reproductive tract and vaginal obstruction. The differential for a neonatal presentation of lower abdominal mass includes urogenital anomalies, Hirschsprung’s, disease or sacrococcygeal teratoma. Prenatal diagnosis and early newborn imaging studies leads to early detection and treatment of these cases. Case. We report here two cases of neonatal hydrocolpos with prenatal diagnosis of lower abdominal mass. Postnatally, ultrasound, MRI imaging, and cystoscopy confirmed large cystic mass as hydrocolpos with distal vaginal obstruction. Both patients had enlarged renal system secondary to mass effect. Conclusion. High index of suspicion for hydrocolpos in a newborn presenting with fetal diagnosis of infraumbilical abdominal mass will facilitate timely intervention and prevention of complications.

    Computed tomography (CT) is used less often than other techniques on neonatal units. However, in the acute setting, CT can be invaluable in diagnosing or excluding potentially life-threatening conditions and guiding initial management in neonates. Common indications for scanning include trauma, suspected non-accidental injury, infection, or an acute hypoxic or metabolic event. The aim of this review is to provide an overview of the normal neonatal head at CT and compare this to the common pathological abnormalities. Several key features of each condition will be highlighted. It is important to note that some pathological conditions can have overlapping features at CT and, therefore, the clinical history and additional investigations are also of key importance in determining the diagnosis

    A cerebral artery infarction is an important differential diagnosis in the newborn with neurological abnormalities. Based on clinical data, its incidence is estimated to be 1 in 4000 newborns. Since the course is often subclinical, the true incidence is probably higher. Diagnosis: Cerebral ultrasound and Doppler sonography as readily available screening tools play a central role in the initial diagnosis of neonatal cerebral infarction. Definitive diagnosis is made by computed tomography or magnetic resonance imaging. Beside symptomatic anticonvulsive therapy, treatment aims at the prevention of secondary ischemic injury. Discussion: Three term infants with different clinical courses of neonatal stroke are presented to sensitize the clinician and the radiologist for this probably underdiagnosed entity. The role of imaging modalities in the diagnosis and follow-up of neonatal cerebral infarction is discussed. (orig.) [de

  2. Neonatal hemophilia: a rare presentation

    Full Text Available Hemophilia A is a X-linked hereditary condition that lead to decreased factor VIII activity, occurs mainly in males. Decreased factor VIII activity leads to increased risk of bleeding events. During neonatal period, diagnosis is made after post-partum bleeding complication or unexpected bleeding after medical procedures. Subgaleal hemorrhage during neonatal period is a rare, severe extracranial bleeding with high mortality and usually related to traumatic labor or coagulation disorders. Subgaleal hemorrhage complications result from massive bleeding. We present a neonate with unremarkable family history and uneventful pregnancy with a vaginal delivery with no instrumentation, presenting with severe subgaleal bleeding at 52 hours of life. Aggressive support measures were implemented and bleeding managed. The unexpected bleeding lead to a coagulation study and the diagnosis of severe hemophilia A. There were no known sequelae. This case shows a rare hemophilia presentation reflecting the importance of coagulation studies when faced with unexplained severe bleeding.

    Acne may present in neonates, infants, and small children. Neonatal and infantile acne vulgaris are not considered to be rare. The presentation of acne in this patient population sometimes represents virilization and may portend later development of severe adolescent acne. Neonatal and infantile acne vulgaris must be distinguished from other cutaneous disorders seen in newborns and infants. Infantile acne tends to be more pleomorphic and inflammatory, thus requiring more vigorous therapy than neonatal acne.

    Neonatal herpes simplex virus (HSV) is an uncommon but devastating infection in the newborn, associated with significant morbidity and mortality. The use of PCR for identification of infected infants and acyclovir for treatment has significantly improved the prognosis for affected infants. The subsequent use of suppressive therapy with oral acyclovir following completion of parenteral treatment of acute disease has further enhanced the long-term prognosis for these infants. This review article will discuss the epidemiology, risk factors and routes of acquisition, clinical presentation, and evaluation of an infant suspected to have the infection, and treatment of proven neonatal HSV disease.

    Methicillin-resistant Staphylococcus aureus (MRSA) nosocomial infections frequently occur in the hospital environment, but their incidence is less often observed in neonates. In the present investigation, seventeen cases were recorded over a nine-week period (two cases per week). Pulsed field gradient gel electrophoresis confirmed the clonal character of the strain. The hypothesis of manually-transmitted infection due to contamination from multiple sources was reinforced by the fact the epidemic persisted in spite of the elimination of the main human infectious source and an absence of risk factors determined by the case-control study. The role of environmental factors in the persistence of this outbreak of MRSA infection has been considered.

Tendo em vista estas características, este estudo objetivou a identificação de estafilococos coagulase-negativos isolados de processos infecciosos em recém-nascidos, bem como a determinação da produção de beta-lactamase e sensibilidade às drogas pelas linhagens isoladas. O Staphylococcus epidermidis foi a espécie mais freqüentemente isolada (77,8%. O estudo da produção de beta-lactamase revelou esta característica na maioria das linhagens de ECN isoladas (71,8%. As linhagens de ECN mostraram, ainda, resistência múltipla aos antibióticos utilizados, com 63,2% dos isolados apresentando resistência a cinco ou mais drogas. A elevada transmissibilidade de plasmídios entre estas linhagens e o uso abusivo de drogas antimicrobianas têm-se constituído em importantes fatores na seleção de amostras multirresistentes e na transferência de genes de resistência.Although coagulase-negative staphylococci (CNS have been recognized as saprophytes for a long time, they had emerged as etiologic agents of infections.

    Twenty-four Staphylococcus species and their subspecies were examined for their susceptibilities to teicoplanin by disk diffusion (30-micrograms disk) and agar dilution for the determination of MICs. Moderately susceptible and resistant clinical strains were further tested for their susceptibilities to oxacillin and vancomycin. Teicoplanin resistance was not observed in the reference strains of the various Staphylococcus species isolated from healthy volunteers or animals. However, the novobiocin-resistant species Staphylococcus saprophyticus, Staphylococcus cohnii, Staphylococcus xylosus, Staphylococcus arlettae, Staphylococcus kloosii, and Staphylococcus gallinarum were less susceptible to teicoplanin (MIC, 2 to 8 micrograms/ml) than most of the novobiocin-susceptible species were (MIC, 0.5 to 4 micrograms/ml). Clinical isolates of coagulase-negative species were generally less susceptible to teicoplanin than were reference strains. Seven percent of the Staphylococcus epidermidis clinical strains were moderately susceptible (MIC, 16 micrograms/ml) to teicoplanin. Of these strains, 70% were oxacillin resistant. For Staphylococcus haemolyticus strains, 11% were resistant (MIC, greater than 16 micrograms/ml) and 21% were moderately susceptible to teicoplanin. Of these strains, 95% were oxacillin resistant, No strains of S. epidermidis or S. haemolyticus were intermediate or resistant to vancomycin. Teicoplanin appears to be less active in vitro against oxacillin-resistant S. haemolyticus. However, teicoplanin is an effective antimicrobial agent against many Staphylococcus species. PMID:1835340

Serum concentrations were 10.8-67.6 micrograms/ml (mean 32.7 +/- 2.8 micrograms/ml) and 25.1-52.0 micrograms/ml (mean 38.9 +/- 4.3 micrograms/ml) in the neonates and the infants, respectively, at their peaks (0.5 hour value), decreased thereafter with half-lives of 0.96-5.59 hours (mean 2.20 +/- 0.26 hours value), and 0.97-1.54 hours (mean 1.22 +/- 0.12 hours value), respectively. Serum levels decreased to 0.2-17.1 micrograms/ml (mean 2.9 +/- 0.6 micrograms/ml) and N.D. -1.1 micrograms/ml (mean 0.4 +/- 0.2 micrograms/ml) after 8 hours, respectively. The urinary recovery rates of the drug in the first 8 hours after administration were 15.0-96.0% (mean 53.7 +/- 4.9%) and 29.9-73.3% (mean 62.4 +/- 9.4%) in the neonates and in the infants, respectively. 2. FMOX was administered to 78 neonates (durations of pregnancy 31-42 weeks, weights at birth 1,420-3,860 g) in whom bacterial infections were established or suspected, and clinical, bacteriological, and side effects were evaluated.

    The indications for neonatal tracheostomy may have changed with current noninvasive respiratory therapies compared with previous decades. To study the current trends in neonatal tracheostomy and identify the primary indication for the procedure and risk factors for failed extubation. This retrospective medical record review included 47 neonates who underwent tracheostomy from January 1, 2009, to December 31, 2013, at the University of Maryland Children's Hospital. Group 1 included infants undergoing tracheostomy for the primary indication of upper airway obstruction; group 2, infants with primary pulmonary disease. Data on weight, gestational age, comorbid conditions, congenital abnormalities, complications, outcomes, and indications for tracheostomy were compared statistically between groups. Differences in gestational age, birth weight, and age at tracheostomy. Among the 47 infants included in the study (30 boys; 17 girls, mean [SD] age, 113 [73] days), 31 (66%) demonstrated anatomical causes of airway obstruction, and 16 (34%) had significant pulmonary disease. Among infants with anatomical causes, subglottic stenosis represented the largest group (11 of 31 [35%]). The mean age at the time of tracheostomy was significantly lower in the group with airway obstruction (98.9 vs 146.9 days; difference, 48 [95% CI, 4.8-91.2] days; P = .04). No procedure-related morbidity or mortality was encountered. Anatomical upper airway obstruction may be returning as the most common indication for a neonatal tracheostomy, thereby supporting the belief that current respiratory therapies have lowered the burden of chronic lung disease and the need for prolonged ventilatory care.

  17. Photodegradation of riboflavin in neonates

    The biologically most important flavins are riboflavin and its related nucleotides, all highly sensitive to light. It is because of its photoreactivity and its presence in almost all body fluids and tissues that riboflavin assumes importance in phototherapy of neonatal jaundice. The absorption maxima of both bilirubin and riboflavin in the body are nearly identical: 445-450 (447) nm. In consequence, blue visible light will cause photoisomerization of bilirubin accompanied by photodegradation of riboflavin. This results in diminished erythrocyte glutathione reductase, which indicates generalized tissue riboflavin deficiency and red cell lysis. Single- and double-strand breaks in intracellular DNA have occurred with phototherapy. This light exposure of neonates may result also in alterations of bilirubin-albumin binding in the presence of both riboflavin and theophylline (the latter frequently given to prevent neonatal apnea). Many newborns, especially if premature, have low stores of riboflavin at birth. The absorptive capacity of premature infants for enteral riboflavin is likewise reduced. Consequently, inherently low stores and low intake of riboflavin plus phototherapy for neonatal jaundice will cause a deficiency of riboflavin at a critical period for the newborn. Supplementation to those infants most likely to develop riboflavin deficiency is useful, but dosage, time, and mode of administration to infants undergoing phototherapy must be carefully adjusted to avoid unwanted side effects

    The International Fetal and Newborn Growth Consortium for the 21(st) Century (INTERGROWTH-21(st) ) is a large-scale, population-based, multicentre project involving health institutions from eight geographically diverse countries, which aims to assess fetal, newborn and preterm growth under optimal conditions. Given the multicentre nature of the project and the expected number of preterm births, it is vital that all centres follow the same standardised clinical care protocols to assess and manage preterm infants, so as to ensure maximum validity of the resulting standards as indicators of growth and nutrition with minimal confounding. Moreover, it is well known that evidence-based clinical practice guidelines can reduce the delivery of inappropriate care and support the introduction of new knowledge into clinical practice. The INTERGROWTH-21(st) Neonatal Group produced an operations manual, which reflects the consensus reached by members of the group regarding standardised definitions of neonatal morbidities and the minimum standards of care to be provided by all centres taking part in the project. The operational definitions and summary management protocols were developed by consensus through a Delphi process based on systematic reviews of relevant guidelines and management protocols by authoritative bodies. This paper describes the process of developing the Basic Neonatal Care Manual, as well as the morbidity definitions and standardised neonatal care protocols applied across all the INTERGROWTH-21(st) participating centres. Finally, thoughts about implementation strategies are presented. © 2013 Royal College of Obstetricians and Gynaecologists.

    To describe the perceptions of nurses in neonatal units on pain management, meet the educational profile and describe the use of pain assessment tools and non-pharmacological management for treatment. Cross-sectional descriptive multicentre study, developed during the months of February to September 2015, in the neonatology services of three hospitals at the Community of Madrid, Spain. Data collection was performed through an ad hoc questionnaire on paper or electronically using Survey Monkey platform. The sample consisted of 142 professionals, with a response rate of 55%: 47.9% (68) confirmed they had received specific training in pain management; 39.5% (56) stated that pain is regularly assessed in the unit; only 43.6% reported using validated scales, the most used being the Premature Infant Pain Profile (PIPP). As for the non-pharmacological management, swaddling and non-nutritive sucking it is the most used, followed by sucrose. Intravenous cannulation was identified as the most painful procedure. Pain management is in the process of improvement, because of training and because there is little pain assessment using validated scales. The improvement in the use of non-pharmacological management for the relief of pain in minor procedures is noteworthy.

    Investigate the incidence, etiological pattern and the antimicrobial resistance of late-onset neonatal infections over a period of 5 years. Longitudinal audit of neonatal sepsis from January 2005 to December 2009, in the main maternity hospital in Kuwait. Late-onset neonatal infection was defined as the culture of a single potentially pathogenic organism from blood or cerebrospinal fluid from an infant older than 6 days in association with clinical or laboratory findings consistent with infection. The overall incidence was 16.9 (95% confidence interval: 15.8-18.0) episodes per 1000 live births. The commonest pathogen was coagulase-negative Staphylococcus, 339 (35.7%), while Klebsiella was the most common gram-negative infection, 178 (18.8%). Escherichia coli, Enterococcus and Enterobacter spp were each responsible for 6% of all infections. Candida caused 104 (11.0%) infections. The general pattern of infection remained unchanged over the study period. Case fatality was 11.7% (95% confidence interval: 9.7-13.9%) and was high for Pseudomonas (18.4%) and Candida (22.1%) infections. Approximately 24 and 20% of Klebsiella infections were resistant to cefotaxime and gentamicin, respectively, while 28 and 24% of Escherichia coli infections were resistant to cefotaxime and gentamicin, respectively. The incidence of late-onset infection in Kuwait is high, resembling that in resource-poor countries. The high incidence coupled with low case fatality provides an example for settings where tertiary care is introduced without strict measures against nosocomial infections. Prevention against nosocomial infections in neonatal units has the potential to further reduce neonatal mortality in these settings. © 2012 The Authors.

    Over a three-month period, 13 neonates developed staphylococcal scalded skin syndrome (SSSS) in a maternity unit, between four and 18 days after their birth. An epidemiological and descriptive study followed by a case-control study was performed. A case was defined as a neonate with blistering or peeling skin, and exfoliative toxin A Staphylococcus aureus positive cultures. Controls were selected at random from the asymptomatic, non-colonized neonates born on the same day as the cases. All staff members and all neonates born during the outbreak period were screened for carriage by nasal swabs and umbilical swabs, respectively. S. aureus isolates were polymerase chain reaction (PCR) screened for etA gene and genotyped by pulsed-field gel electrophoresis (PFGE). Two clusters of eight and five cases were identified. Receiving more than one early umbilical care procedure by the same ancillary nurse was the only risk factor identified in the case-control study (odds ratio=15, 95% confidence intervals 2-328). The ancillary nurse suffered from chronic dermatitis on her hands that favoured S. aureus carriage. Exfoliative-toxin-A-producing strains, as evidenced by PCR and indistinguishable by PFGE, were isolated from all but one of the SSSS cases, from four asymptomatic neonates, from two staff members and from the ancillary nurse's hands. Removal of the ancillary nurse from duty, infection control measures (isolation precautions, chlorhexidine handwashing and barrier protections), and treatment of the carriers (nasal mupirocin and chlorhexidine showers) led to control of the epidemic. In conclusion, this study emphasizes the need for tight surveillance of chronic dermatitis in healthcare workers.

    A cerebral artery infarction is an important differential diagnosis in the newborn with neurological abnormalities. Based on clinical data, its incidence is estimated to be 1 in 4000 newborns. Since the course is often subclinical, the true incidence is probably higher. Diagnosis: Cerebral ultrasound and Doppler sonography as readily available screening tools play a central role in the initial diagnosis of neonatal cerebral infarction. Definitive diagnosis is made by computed tomography or magnetic resonance imaging. Beside symptomatic anticonvulsive therapy, treatment aims at the prevention of secondary ischemic injury. Discussion: Three term infants with different clinical courses of neonatal stroke are presented to sensitize the clinician and the radiologist for this probably underdiagnosed entity. The role of imaging modalities in the diagnosis and follow-up of neonatal cerebral infarction is discussed. (orig.)

  17. Acute symptomatic neonatal seizures in preterm neonates: etiologies and treatments.

    Pisani, Francesco; Spagnoli, Carlotta

    2017-12-15

    Acute symptomatic neonatal seizures in preterm newborns are a relevant clinical challenge due to the presence of many knowledge gaps. Etiology-wise, acute symptomatic seizures have an age-specific epidemiology, with intraventricular hemorrhage and its complications representing the first cause in extremely and very preterm neonates, whereas other etiologies have similar occurrence rates as in full-term infants. Specific treatment strategies for the premature neonates are not yet available. Studies suggest a similarly low response rate with even more unfavorable prognosis than in full-term infants. Pharmacodynamic and pharmacokinetic changes are likely under way during the preterm period, with the potential to affect both effectiveness and safety of antiepileptic drugs in these patients. However, due to the lack of clear evidence to guide prioritization of second-line drugs, off-label medications are frequently indicated by review papers and flow-charts, and are prescribed in clinical practice. We therefore conclude by exploring potential future lines of research. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The aim of this study was to isolate and characterize methicillin-resistant staphylococci (MRS) in a small animal clinic and to investigate their distribution and possible transmission. Swabs (n=72) were taken from hospitalized pets, the environment and employees of a small animal clinic and screened for the presence of MRS. The staphylococcal species was confirmed biochemically or by 16S rDNA sequencing. Susceptibility to antimicrobial agents was tested by broth dilution. The presence of mecA and other resistance genes was confirmed by PCR. Molecular typing of the isolates followed standard procedures. In total, 34 MRS belonging to the four species Staphylococcus aureus (n=5), Staphylococcus epidermidis (n=21), Staphylococcus haemolyticus (n=6) or Staphylococcus pettenkoferi (n=2) were isolated. All isolates were multidrug-resistant with resistance to at least three classes of antimicrobial agents. Among the five methicillin-resistant S. aureus (MRSA) isolates, four belonged to the clonal complex CC398; two of them were isolated from cats, the remaining two from pet cages. Overall, the MRS isolates differed in their characteristics, except for one S. epidermidis clone (n=9) isolated from hospitalized cats without clinical staphylococcal infections, pet cages, the clinic environment as well as from a healthy employee. This MRSE clone was resistant to 10 classes of antimicrobial agents, including aminocyclitols, β-lactams, fluoroquinolones, lincosamides, macrolides, phenicols, pleuromutilins, sulfonamides, tetracyclines and trimethoprim. These findings suggest a possible transmission of specific MRS isolates between animal patients, employees and the clinic environment. Copyright © 2013 Elsevier B.V. All rights reserved.

    Neonatal hyperglycemia is a metabolic disorder found in the neonatal intensive care units. Neonatal diabetes mellitus (NDM) is a very uncommon cause of hyperglycemia in the newborn, occurring in 1 in every 400,000 births. There are two subtypes of neonatal diabetes mellitus: permanent neonatal diabetes mellitus (PNDM) and transient neonatal diabetes mellitus (TNDM). We describe a term, small for gestational age, female neonate with transient neonatal diabetes mellitus who presented with poor feeding tolerance and vomiting associated with hyperglycemia (385 mg/dL), glycosuria, and metabolic acidosis within the first 12 hours of life. The neonate was treated with intravenous insulin, obtaining a slight control of hyperglycemia. An adequate glycemia was achieved at 5 weeks of life. The molecular studies showed complete loss of maternal methylation at the TND differentially methylated region on chromosome 6q24. The etiology of this neonate's hyperglycemia was a hypomethylation of the maternal TND locus. A rare cause of neonatal diabetes mellitus must be considered if a neonate presents refractory hyperglycemia. To our knowledge, this is the first case reported in Puerto Rico of transient neonatal mellitus due to the uncommon mechanism of maternal hypomethylation of the TND locus. Its prevalence in Puerto Rico is unknown.

    Purpose Hypocalcemia is a common endocrinological condition in 22q11.2 deletion syndrome. Neonatal hypocalcemia may affect neurodevelopment. We hypothesized that neonatal hypocalcemia would be associated with rare, more severe forms of intellectual disability in 22q11.2 deletion syndrome. Methods We used a logistic regression model to investigate potential predictors of intellectual disability severity, including neonatal hypocalcemia, neonatal seizures, and complex congenital heart disease, e.g., interrupted aortic arch, in 149 adults with 22q11.2 deletion syndrome. Ten subjects had moderate-to-severe intellectual disability. Results The model was highly significant (P < 0.0001), showing neonatal seizures (P = 0.0018) and neonatal hypocalcemia (P = 0.047) to be significant predictors of a more severe level of intellectual disability. Neonatal seizures were significantly associated with neonatal hypocalcemia in the entire sample (P < 0.0001), regardless of intellectual level. There was no evidence for the association of moderate- to-severe intellectual disability with other factors such as major structural brain malformations in this sample. Conclusion The results suggest that neonatal seizures may increase the risk for more severe intellectual deficits in 22q11.2 deletion syndrome, likely mediated by neonatal hypocalcemia. Neonatal hypocalcemia often remains unrecognized until the postseizure period, when damage to neurons may already have occurred. These findings support the importance of early recognition and treatment of neonatal hypocalcemia and potentially neonatal screening for 22q11.2 deletions. PMID:23765047

Objetivo: exponer los resultados de nuestra experiencia en el tratamiento de recién nacidos con perforación gástrica, y revisar el estado actual del conocimiento sobre esta nosología. Métodos: se realizó una investigación descriptiva, retrospectiva, con la totalidad de los recién nacidos ingresados en la sala de neonatología quirúrgica del Hospital Pediátrico Universitario "William Soler", diagnosticados con perforación gástrica, durante el período comprendido entre enero de 1990 y diciembre de 2010. Resultados: se trataron 8 pacientes, de los cuales 3 se consideraron como idiopáticos. El neumoperitoneo estuvo presente en la totalidad de los pacientes. El fundus gástrico y la cara anterior del órgano constituyeron los sitios más frecuentemente afectados. Por su lado, la prematuridad no guardó una clara relación con la ocurrencia de la perforación. En la mayoría de los pacientes se realizó una reparación primaria de la perforación sin gastrostomía. La mortalidad general en el estudio fue de un 62 %, y fue la peritonitis la complicación más frecuente. Conclusiones: la perforación gástrica neonatal constituye una entidad altamente letal, en la cual las distintas alternativas de tratamiento quirúrgico no son, en definitiva, por sí solas, la solución para lograr una adecuada sobrevida.Introduction: present like a real surgical emergence, the neonatal gastric perforation is a challenge for all physicians working in this field.

    To analyze the change in drug resistance of Staphylococcus aureus (SAU) in the PLA general hospital from January 2008 to December 2012, and to provide solid evidence to support the rational use of antibiotics for clinical applications. The SAU strains isolated from clinical samples in the hospital were collected and subjected to the Kirby-Bauer disk diffusion test. The results were assessed based on the 2002 American National Committee for Clinical Laboratory Standards (NCCLS) guidelines. SAU strains were mainly isolated from sputum, urine, blood and wound excreta and distributed in penology, neurology wards, orthopedics and surgery ICU wards. Except for glycopeptide drugs, methicillin-resistant Staphylococcus aureus (MRSA) had a higher drug resistance rate than those of the other drugs and had significantly more resistance than methicillin-sensitive Staphylococcus aureus (MSSA) (P resistance, we discovered a gradual increase in drug resistance to fourteen test drugs during the last five years. Drug resistance rate of SAU stayed at a higher level over the last five years; moreover, the detection ratio of MRSA keeps rising year by year. It is crucial for physicians to use antibiotics rationally and monitor the change in drug resistance in a dynamic way.

    Full Text Available OBJETIVO: investigar o nível de consciência dos pais em relação à importância da triagem auditiva neonatal, bem como verificar os motivos do não comparecimento ao retorno agendado após a primeira avaliação. MÉTODO: a casuística foi constituída por 31 mães e/ou responsáveis dos recém-nascidos da unidade neonatal do Hospital Universitário de Maringá, os quais não compareceram ao reteste agendado após a alta hospitalar. RESULTADOS: os motivos apresentados pelas mães e/ou responsáveis para o não comparecimento ao retorno agendado envolveram atitudes que puderam sinalizar pouca importância atribuída às questões relacionadas à audição e a Triagem Auditiva Neonatal, pois sugiram motivos irrelevantes como o esquecimento do retorno, mãe pensou que o bebê não deixaria ser submetido ao exame e a perda de horário para nova avaliação. Tal fato, provavelmente reflete a falta de conscientização por parte das mães dos recém-nascidos quanto à importância da Triagem Auditiva Neonatal. CONCLUSÃO: existe a necessidade de aumentar a conscientização geral em relação à Triagem Auditiva Neonatal, por parte dos familiares e dos profissionais que atuam diretamente com os recém-nascidos, os quais contribuirão para a agilidade do processo diagnóstico, garantindo melhores perspectiva ao futuro de crianças portadoras de deficiência auditiva.

    2015-01-01

    Full Text Available Neonatal pustular eruption is a group of disorders characterized by various forms of pustulosis seen in first 4 weeks of life. Its presentation is often similar with some subtle differences, which can be further established by few simple laboratory aids, to arrive at a definite diagnosis. Given their ubiquitous presentation, it is sometimes difficult to differentiate among self-limiting, noninfectious, pustular dermatosis such as erythema toxicum neonatorum, transient neonatal pustular melanosis, miliaria pustulosa, etc., and potentially life threatening infections such as herpes simplex virus and varicella zoster virus infections. This review article tries to address the chronological, clinical, morphological, and histological differences among the various pustular eruptions in a newborn, in order to make it easier for a practicing dermatologist to diagnose and treat these similar looking but different entities of pustulation with a clear demarcation between the physiological benign pustular rashes and the infectious pustular lesions.

  10. Maternal Preeclampsia and Neonatal Outcomes

    2011-01-01

    Full Text Available Preeclampsia is a multiorgan, heterogeneous disorder of pregnancy associated with significant maternal and neonatal morbidity and mortality. Optimal strategies in the care of the women with preeclampsia have not been fully elucidated, leaving physicians with incomplete data to guide their clinical decision making. Because preeclampsia is a progressive disorder, in some circumstances, delivery is needed to halt the progression to the benefit of the mother and fetus. However, the need for premature delivery has adverse effects on important neonatal outcomes not limited to the most premature infants. Late-preterm infants account for approximately two thirds of all preterm deliveries and are at significant risk for morbidity and mortality. Reviewed is the current literature in the diagnosis and obstetrical management of preeclampsia, the outcomes of late-preterm infants, and potential strategies to optimize fetal outcomes in pregnancies complicated by preeclampsia.

    Full Text Available Christina L Boull, Kristen P Hook Department of Dermatology, Division of Pediatric Dermatology, University of Minnesota, Minneapolis, MN, USA Abstract: Neonatal erythroderma is rare, but significant as it may be the initial manifestation of an array of infectious, metabolic, and genetic conditions, some of which are life-threatening. Initial management should focus on identifying and treating life threatening etiololgies and complications, including infection, and fluid, electrolyte, and temperature disturbances. Often, the etiology of erythroderma is difficult to quickly identify in the neonate, as there is significant clinical overlap between causative entities. Furthermore, rapid definitive diagnostic tests are lacking. Herein we provide a review of the specific clinical features and diagnostic tests, which can aid in making a correct diagnosis. Skin care for the erythrodermic infant is also discussed. We encourage subspecialist consultation when appropriate to aid in the evaluation, especially when initial testing is nondiagnostic.

    Background. Newborn infants are particularly prone to hypothermia, a condition with a high mortality. Objective. To study the CT brain patterns in infants with hypothermia and neurological symptoms. Materials and methods. We reviewed the brain CT of nine infants with neonatal hypothermia, multiple organ failure, seizures and coma. Results. Two infants had normal CT scans, acutely and at follow-up, and were clinically normal at follow-up. In seven infants, CT showed diffuse cerebral oedema, with reversal of the normal density relationship between grey and white matter and a relative increased density of the thalami, brainstem and cerebellum - the 'reversal sign'. In six surviving infants with severe developmental delay, follow-up CT revealed cerebral atrophy with multicystic encephalomalacia. Conclusions. The 'reversal sign' has been described in the abused child, birth asphyxia and anoxia due to drowning. Neonatal hypothermia is offered as a further cause. (orig.)

    Aseptic model minces were inoculated with commercial samples of either Staphylococcus xylosus or Staphylococcus carnosus. Volatiles produced by the cultures were collected during growth by diffusive sampling onto adsorbent traps, identified by thermal desorption-gas chromatography-mass spectrometry...... and quantified by thermal desorption-gas chromatography-flame ionisation. The data were analysed by principal component analysis. The study showed that both starter cultures produced a large number of volatiles in concentrations of sensory importance. Almost all of the major volatiles resulted from amino acid...... degradation, suggesting that the effect of Staphylococcus starter cultures on flavour quality is much related to their ability of catabolizing amino acids. With the exception of diacetyl, acetoin and 2-methyl-1-butanol, both cultures formed the same volatiles. Diacetyl and acetoin were not produced...

    Jaundice is more or less common in newborn babies. Through physiological jaundice is most common cause of neonatal jaundice, possibility of obstructive jaundice especially biliary atresia should be kept in mind. Early diagnosis of biliary atresia followed by surgical treatment can save baby's life. Otherwise death is inevitable due to liver failure. Hepatobiliary scan is the imaging study of choice in neonatal jaundice especially when there is persistent conjugated hyperbilirubinaemia. Total 27 newborn babies of suspected biliary atresia, aged 14 days to 4 months were referred to Institute of Nuclear Medicine for Hepatobiliary scan. All of them had high serum bilirubin ranged from 6.0 mg/dl with an average of 9.35 ng/dl serum bilirubin level. Ultrasonography of hepatobiliary system was performed in 14 cases showing normal sized liver in 4 cases and hepatomegaly in 10 cases. Hepatobiliary scan was done with 99m Tc-Mebrofenin (Br IDA) after preparing the baby with phenobarbitone for 3-5 days. 20 (67%) cases were scan positive suggesting biliary atresia (BA) and 7(27%) cases were scan negative. In BA there will be increased hepatic uptake of the radionuclide without any significant excretion even in 24 hours delayed images. Presence of radiotracer in the bowel exclude the diagnosis of BA. Early diagnosis of biliary atresia is very important because in this condition surgery should be performed early (within 60 days of life). Studies suggest that hepatobiliary scan after hepatic stimulation with phenobarbitone for a period of 3-5 days is highly accurate for differentiating biliary atresia from other causes of neonatal jaundice. It is very important to perform hepatobiliary scan in a case of neonatal jaundice to exclude biliary atresia for the sake of baby's life.(author)

  16. Systemic fungal infections in neonates

    Full Text Available Advances in neonatal management have led to considerable improvement in newborn survival. However, early (72hours onset systemic infections, both bacterial and fungal, remain a devastating complication and an important cause of morbidity and mortality in these babies. Most neonatal fungal infections are due to Candida species, particularly Candida albicans. The sources of candidiasis in NICU are often endogenous following colonization of the babies with fungi. About 10% of these babies get colonized in first week of life and up to 64% babies get colonized by 4 weeks of hospital stay. Disseminated candidiasis presents like bacterial sepsis and can involve multiple organs such as the kidneys, brain, eye, liver, spleen, bone, joints, meninges and heart. Confirming the diagnosis by laboratory tests is difficult and a high index of suspicion is required. The diagnosis of fungemia can be made definitely only by recovering the organism from blood or other sterile bodily fluid. Amphotericin B continues to be the mainstay of therapy for systemic fungal infections but its use is limited by the risks of nephrotoxicity and hypokalemia. Newer formulations of amphotericin B, namely the liposomal and the lipid complex forms, have recently become available and have been reported to have lesser toxicity. More recently Indian liposomal Amphotericin B derived from neutral lipids (L-Amp -LRC-1 has shown good response with less toxicity. A clinical trial with this preparation has shown to be safe and efficacious in neonatal fungal infections. Compared to other liposomal preparations, L-Amp-LRC-1 is effective at lower dose and is less expensive drug for the treatment of neonatal candidiasis.

    To study the clinical characteristics, pathogenic bacteria, and antibiotics resistance of neonatal purulent meningitis in order to provide the guide for early diagnosis and appropriate treatment. A retrospective review was performed and a total of 112 cases of neonatal purulent meningitis (male 64, female 58) were identified in the neonatal intensive care unit of Yuying Children's Hospital of Wenzhou Medical University seen from January 1, 2004 to December 31, 2013. The clinical information including pathogenic bacterial distribution, drug sensitivity, head imageology and therapeutic outcome were analyzed. Numeration data were shown in ratio and chi square test was applied for group comparison. Among 112 cases, 46 were admitted from 2004 to 2008 and 66 from 2009 to 2013, 23 patients were preterm and 89 were term, 20 were early onset (occurring within 3 days of life) and 92 were late onset meningitis (occurring after 3 days of life). In 62 (55.4%) cases the pathogens were Gram-positive bacteria and in 50 (44.6%) were Gram-negative bacteria. The five most frequently isolated pathogens were Escherichia coli (32 cases, 28.6%), coagulase-negative staphylococcus (CNS, 20 cases, 17.9%), Streptococcus (18 cases, 16.1%, Streptococcus agalactiae 15 cases), Enterococci (13 cases, 11.6%), Staphylococcus aureus (9 cases, 8.0%). Comparison of pathogenic bacterial distribution between 2004-2008 and 2009-2013 showed that Gram-positive bacteria accounted for more than 50% in both period. Escherichia coli was the most common bacterium, followed by Streptococcus in last five years which was higher than the first five years (22.7% (15/66) vs. 6.5% (3/46), χ(2) = 5.278, P bacteria in early onset meningitis and higher than those in late onset meningitis (35.0% (7/20) vs. 12.0% (11/92), χ(2) = 4.872, P pathogens responsible for neonatal purulent meningitis over the past ten years. There were increasing numbers of cases with Streptococcus meningitis which are more common in early onset

    To measure the true prevalence of hearing impairment in neonates in Tafila, Jordan. This retrospective study was carried out at Prince Zeid Hospital, Taflia, Jordan through analysis of data of all births from January 2005 and January 2006. Transient evoked otoacoustic emissions (TEOAE) were measured via the application of echoprobe to both ears. There were two groups of births that were analysed statistically. Hearing impaired neonates were those with two fails or more in each ear. Normal ones were those with 3 pass or more. Of the 1788 babies in the study group, 1622 (90.7%) were enrolled in the study with 9.3% loss rate. 1512 babies were examined on the 2 day of birth, 2 of them had hearing impairment with a rate of 1.2/1000. 110 babies were screened on the day of discharge from the nursery, one of them with hearing defect with a rate of 5.9/1000. Thus, true prevalence of hearing impaiment or failure was 1.7/1000. We conclude that screening for hearing impairment in the neonatal period is easy, informative and the true prevalence of hearing impairment in Tafila is similar to that in different parts of the world.

    Full Text Available Anaerobic bacteria are well known causes of sepsis in adults but there are few studies regarding their role in neonatal sepsis. In an attempt to define the incidence of neonatal anaerobic infections a prospective study was performed during one year period. A total number of 400 neonates under sepsis study were entered this investigation. Anaerobic as well as aerobic cultures were sent. The patients were subjected to comparison in two groups: anaerobic culture positive and anaerobic culture negative and this comparison were analyzed statistically. There were 7 neonates with positive anaerobic culture and 35 neonates with positive aerobic culture. A significant statistical relationship was found between anaerobic infections and abdominal distention and pneumonia. It is recommended for those neonates with abdominal distention and pneumonia refractory to antibiotic treatment to be started on antibiotics with anaerobic coverage.

    Neonatal suppurative parotitis is a rare disease. Only 32 cases were reported in the English-language literature between 1970 and 2004. We searched Medline for acute, neonatal, bacterial, suppurative, parotitis, facial, preauricular swelling starting from 1970, limiting our search to the English-language literature. We reviewed all the reported cases together with three more managed in our department. We identified nine new cases since 2004. The total number of patients reviewed was 44, including our patients. Most of them were male (77%). The majority developed unilateral inflamed parotid swelling (77%) and exuded pus from the ipsilateral Stensen duct. Fever was seen in fewer than half of them (47%). Premature babies constituted a third of the patients. Staphylococcus aureus was the leading causative agent (61%). Most patients responded well to conservative treatment with antibiotics (77%). The most frequently used combination of antibiotics was an anti-staphylococcal agent with either an aminoglycoside or a third-generation cephalosporin. A minority required surgical drainage. No deaths were reported in the group studied after 1970. Neonatal suppurative parotitis is rare but easy to diagnose and if readily treated with appropriate antibiotics the outcome is excellent. © 2012 The Authors.

    Full Text Available Outbreaks of nosocomial pathogens are one of the most relevant problems in Neonatal Intensive Care Unit (NICU. Many factors contribute to the onset of an epidemic, including virulence of the pathogen and vulnerability of the infants hospitalized in NICU. Outbreaks are often caused by multidrug-resistant organisms (MDROs. MDROs are defined as microorganisms, predominantly bacteria, that are resistant to one or more classes of antimicrobial agents. MDROs, including methicillin-resistant Staphylococcus aureus (MRSA, vancomycin-resistant enterococci (VRE and certain gram-negative bacilli (GNB, have important infection control implications. Once MDROs are introduced into a healthcare setting, transmission and persistence of the resistant strain is determined by the availability of vulnerable patients, selective pressure exerted by antimicrobial use, increased potential for transmission from larger numbers of infected or colonized patients (“colonization pressure”, and the impact of adherence to prevention efforts. Often, routine infection control measures are not enough to contain outbreaks, and additional control measures are needed, including implementation of hand hygiene, cohorting of infected/colonized infants, neonatal surveillance cultures, screening of healthcare workers and decolonization of neonates and/or healthcare workers in selected cases. In this review, we report the practices we developed in our NICU to contain an epidemic. These recommendations reflect the experience of the group, as well as the findings of the current literature.

    Asymmetry of the neonatal brain is not yet understood at the level of structural connectivity. We utilized DTI deterministic tractography and structural network analysis based on graph theory to determine the pattern of structural connectivity asymmetry in 124 normal neonates. We tracted white matter axonal pathways characterizing interregional connections among brain regions and inferred asymmetry in left and right anatomical network properties. Our findings revealed that in neonates, small-...

    Full Text Available A majority of cochlear implant infections are caused by Staphylococcus aureus or Pseudomonas aeruginosa. Reported here is a pediatric patient with a cochlear implant infection caused by methicillin-resistant Staphylococcus lugdunensis, a coagulase-negative Staphylococcus that has only recently been determined to be clinically relevant (1988. Unlike other coagulase-negative Staphylococcus, it is more aggressive, carrying a greater potential for tissue destruction. In pediatrics, the organism is uncommon, poorly described, and generally pan-susceptible. Described herein is the presentation and management of this unusual organism in a pediatric setting.

    Full Text Available Neonatal hyperglycemia is a metabolic disorder found in the neonatal intensive care units. Neonatal diabetes mellitus (NDM is a very uncommon cause of hyperglycemia in the newborn, occurring in 1 in every 400,000 births. There are two subtypes of neonatal diabetes mellitus: permanent neonatal diabetes mellitus (PNDM and transient neonatal diabetes mellitus (TNDM. We describe a term, small for gestational age, female neonate with transient neonatal diabetes mellitus who presented with poor feeding tolerance and vomiting associated with hyperglycemia (385 mg/dL, glycosuria, and metabolic acidosis within the first 12 hours of life. The neonate was treated with intravenous insulin, obtaining a slight control of hyperglycemia. An adequate glycemia was achieved at 5 weeks of life. The molecular studies showed complete loss of maternal methylation at the TND differentially methylated region on chromosome 6q24. The etiology of this neonate’s hyperglycemia was a hypomethylation of the maternal TND locus. A rare cause of neonatal diabetes mellitus must be considered if a neonate presents refractory hyperglycemia. To our knowledge, this is the first case reported in Puerto Rico of transient neonatal mellitus due to the uncommon mechanism of maternal hypomethylation of the TND locus. Its prevalence in Puerto Rico is unknown.

    Full Text Available BACKGROUND Neonatal conjunctivitis is eye discharge in neonates and it is a common infection in neonates in the first month of life. Worldwide, the incidence of neonatal conjunctivitis varies from 1% to 33% depending on the socioeconomic status of the people in the region. In India, the incidence varies from region to region from 0.9 to 35%. MATERIALS AND METHODS Single center prospective study. All neonates of age 0-30 days delivered and referred from neonatal ward of Chengalpattu Medical College and Hospital with complaints of eye swelling, redness, conjunctival discharge to the eye department for treatment are included in the study. RESULTS In this study, age group from 0-7 days were most commonly affected by neonatal conjunctivitis. Both eyes were commonly affected together. Neonates born by both LSCS and normal vaginal delivery were almost equally affected. The most common organism found in culture and Gram staining was staphylococci. CONCLUSION Neonatal conjunctivitis is more likely to be acquired postnatally. It acquires during the 1 st week and responds well to local application of antibiotics, which covers common causative bacteria.

    While vaccines have been tremendously successful in reducing the incidence of serious infectious diseases, newborns remain particularly vulnerable in the first few months of their life to life-threatening infections. A number of challenges exist to neonatal vaccination. However, recent advances in the understanding of neonatal immunology offer insights to overcome many of those challenges. This review will present an overview of the features of neonatal immunity which make vaccination difficult, survey the mechanisms of action of available vaccine adjuvants with respect to the unique features of neonatal immunity, and propose a possible mechanism contributing to the inability of neonates to generate protective immune responses to vaccines. We surveyed recent published findings on the challenges to neonatal vaccination and possible intervention strategies including the use of novel vaccine adjuvants to develop efficacious neonatal vaccines. Challenges in the vaccination of neonates include interference from maternal antibody and excessive skewing towards Th2 immunity, which can be counteracted by the use of proper adjuvants. Synergistic stimulation of multiple Toll-like receptors by incorporating well-defined agonist-adjuvant combinations to vaccines is a promising strategy to ensure a protective vaccine response in neonates. © 2016 S.

    Thyroid hormones have been shown to be absolutely necessary for early brain development. During pregnancy, both maternal and foetal thyroid hormones contribute to foetal brain development and maternal supply explains why most of the athyreotic newborns usually do not show any signs of hypothyroidism at birth. Foetal and/or neonatal hypothyroidism is a rare disorder. Its incidence, as indicated by neonatal screening, is about 1:4000. Abnormal thyroid development (i.e. agenesia, ectopic gland, hypoplasia) or inborn errors in thyroid hormone biosynthesis are the most common causes of permanent congenital hypothyroidism. Recent studies reported that mutations involving Thyroid Transcriptor Factors (TTF) such as TTF-1, TTF-2, PAX-8 play an important role in altered foetal thyroid development. Deficiency of transcriptor factor (Pit-1, Prop-1, LHX-3) both in mother and in the foetus represents another rare cause of foetal hypothyroidism. At birth clinical picture may be not always so obvious and typical signs appear only after several weeks but a delayed diagnosis could have severe consequences consisting of delayed physical and mental development. Even if substitutive therapy is promptly started some learning difficulties might still arise suggesting that intrauterine adequate levels of thyroid hormones are absolutely necessary for a normal neurological development. Placental transfer of maternal antithyroid antibodies inhibiting fetal thyroid function can cause transient hypothyroidism at birth. If the mother with thyroid autoimmune disease is also hypothyroid during pregnancy and she doesn't receive substitutive therapy, a worse neurological outcome may be expected for her foetus. Foetal and/or neonatal hyperthyroidism is a rare condition and its incidence has been estimated around 1:4000-40000, according to various authors. The most common causes are maternal thyroid autoimmune disorders, such as Graves' disease and Hashimoto's thyroiditis. Rarer non autoimmune causes

El objetivo de este estudio es describir las modificaciones registradas en dichas tasas en Andalucía en el último cuarto de siglo. Métodos: Se han calculado las tasas anuales de mortalidad infantil, neonatal precoz y tardía, así como post-neonatal en 1975- 1998. Mediante regresión de Poisson se han estimado los porcentajes anuales de cambio de las tasas en los dos intervalos de 1975-1986 y 1987-1998 así como en el periodo completo 1975-1998. Se ha analizado también la mortalidad proporcional por causas infecciosas, respiratorias, congénitas, afecciones originadas en el periodo perinatal y el resto de causas, así como la razón de tasas de mortalidad por afecciones originadas en el periodo perinatal y para el total de causas, en el quinquenio 1994-98 respecto al quinquenio 1975-79, en los periodos infantil, neonatal (precoz y tardío y postneonatal. Resultados: Los mayores descensos porcentuales se han producido en la mortalidad neonatal precoz (6,38% y tardía (4,6%. La razón de tasas de mortalidad por afecciones originadas en el periodo perinatal entre 1994-98 y 1975-79 es 10 para la mortalidad postneonatal mientras que es inferior a 1 para la mortalidad neonatal tardía (0,63, precoz (0,33 e infantil (0,30. Conclusiones: La mortalidad en los periodos infantil, neonatal precoz, tardío y post-neonatal ha descendido acusadamente entre 1975 y 1998. El riesgo de fallecer por afecciones originadas en el periodo perinatal de los niños con más de 4 semanas y menos de 1 año de vida (periodo postneonatal se ha multiplicado por diez entre 1975-79 y 1994-98.

    We describe an outbreak of Bullous Impetigo (BI), caused by a (methicillin susceptible, fusidic acid resistant) Staphylococcus aureus (SA) strain, spa-type t408, at the neonatal and gynaecology ward of the Jeroen Bosch hospital in the Netherlands, from March-November 2011. We performed an outbreak investigation with revision of the hygienic protocols, MSSA colonization surveillance and environmental sampling for MSSA including detailed typing of SA isolates. Spa typing was performed to discriminate between the SA isolates. In addition, Raman-typing was performed on all t408 isolates. Nineteen cases of BI were confirmed by SA positive cultures. A cluster of nine neonates and three health care workers (HCW) with SA t408 was detected. These strains were MecA-, PVL-, Exfoliative Toxin (ET)A-, ETB+, ETAD-, fusidic acid-resistant and methicillin susceptible. Eight out of nine neonates and two out of three HCW t408 strains yielded a similar Raman type. Positive t408 HCW were treated and infection control procedures were reinforced. These measures stopped the outbreak. We conclude that treatment of patients and HCW carrying a predominant SA t408, and re-implementing and emphasising hygienic measures were effective to control the outbreak of SA t408 among neonates.

    This work examines the antimicrobial resistance of potentially pathogenic bacteria (Staphylococcus pseudintermedius, Streptococcus canis, Escherichia coli) found in the vaginal tract in prepartum mammary secretions and postpartum milk of bitches housed in breeding kennels (N = 20; 92 bitches). The kennels were divided into three categories: no routine antimicrobial administration around parturition (category 1); routine administration of one antibiotic around parturition (category 2); routine administration of multiple antimicrobials around parturition (category 3). Bacteriological cultures and antibiotic susceptibility tests were performed on vaginal specimens, prepartum mammary secretions, and postpartum milk. Stillbirths and neonatal deaths were recorded for each whelping and analyzed as "within-litter stillbirths" and "within-litter neonatal deaths" according to kennel category, by Pearson χ(2) test and the Kruskal-Wallis nonparametric test, respectively. The frequency of isolation and antimicrobial resistance of bacteria were analyzed according to kennel category by Pearson χ(2) test. Kennel category was not significantly associated with differing numbers of stillbirths or neonatal death events, nor was the frequency of isolation of potentially pathogenic bacteria in the three kennel categories significantly different. Kennel category 3 had a significantly higher frequency of isolation of multiresistant gram-positive bacterial strains. Our results show that intense administration of antibiotics to breeding bitches does not effectively reduce neonatal mortality; on the contrary, it induces multiresistance in potentially pathogenic bacteria. Breeders and veterinarians should be aware of the risk of selecting pathogenic bacteria by uncontrolled treatment in prepartum bitches. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available Resumen: La interacción entre variables es una característica inherente de los procesos multivariables, que dificulta su operación y el diseño de sus sistemas de control. Bajo el paradigma de Control por desacoplo se agrupan un conjunto de metodologías, que tradicionalmente han estado orientadas a eliminar o reducir la interacción, y que recientemente algunos investigadores han reorientado con objetivos de solucionar un problema tan complejo como es el control multivariable. Parte del material descrito en este artículo es bien conocido en el campo del control de procesos, pero la mayor parte de él son resultados de varios años de investigación de los autores en los que han primado la generalización del problema, la búsqueda de soluciones de fácil implementación y la combinación de bloques elementales de control PID. Esta conjunción de intereses provoca que no siempre se pueda conseguir un desacoplo perfecto, pero que sí se pueda conseguir una considerable reducción de la interacción en el nivel básico de la pirámide de control, en beneficio de otros sistemas de control que ocupan niveles jerárquicos superiores. El artículo resume todos los aspectos básicos del Control por desacoplo y su aplicación a dos procesos representativos: una planta experimental de cuatro tanques acoplados y un modelo 4×4 de un sistema experimental de calefacción, ventilación y aire acondicionado. Abstract: The interaction between variables is inherent in multivariable processes and this fact may complicate their operation and control system design. Under the paradigm of decoupling control, several methodologies that traditionally have been addressed to cancel or reduce the interactions are gathered. Recently, this approach has been reoriented by several researchers with the aim to solve such a complex problem as the multivariable control.

    To determine the nature and frequency of painful procedures and procedural pain management practices in neonatal units in Kenya. Cross-sectional survey. Level I and level II neonatal units in Kenya. Ninety-five term and preterm neonates from seven neonatal units. Medical records of neonates admitted for at least 24 h were reviewed to determine the nature and frequency of painful procedures performed in the 24 h period preceding data collection (6:00 to 6:00) as well as the pain management interventions (eg, morphine, breastfeeding, skin-to-skin contact, containment, non-nutritive sucking) that accompanied each procedure. Neonates experienced a total of 404 painful procedures over a 24 h period (mean=4.3, SD 2.0; range 1-12); 270 tissue-damaging (mean=2.85, SD 1.1; range 1-6) and 134 non-tissue-damaging procedures (mean=1.41, SD 1.2; range 0-6). Peripheral cannula insertion (27%) and intramuscular injections (22%) were the most common painful procedures. Ventilated neonates and neonates admitted in level II neonatal units had a higher number of painful procedures than those admitted in level I units (mean 4.76 vs 2.96). Only one procedure had a pain intensity score documented; and none had been performed with any form of analgesia. Neonates in Kenya were exposed to numerous tissue-damaging and non-tissue-damaging procedures without any form of analgesia. Our findings suggest that education is needed on how to assess and manage procedural pain in neonatal units in Kenya. Published by the BMJ Publishing Group Limited.

    Full Text Available Background: Jaundice is a common condition among neonates. Prolonged unconjugated hyperbilirubinemia occurs when jaundice persists beyond two weeks in term neonates and three weeks in preterm neonates. This study aimed to determine the etiologies of prolonged unconjugated hyperbilirubinemia in infants admitted to the neonatal ward of Besat Hospital in Hamadan, Iran. Methods: This study was conducted on all infants diagnosed with prolonged unconjugated hyperbilirubinemia during 2007-2012 in the neonatal ward of Besat Hospital in Hamadan, Iran. Demographic characteristics of infants, physical examination and laboratory findings were collected and analyzed to determine the etiologies of neonatal hyperbilirubinemia. Results: In total, 100 infants diagnosed with neonatal hyperbilirubinemia were enrolled in this study, including 49 male and 51 female neonates with mean age of 20±1 days and mean bilirubin level of 17.5±4.0 mg/dL. Main causes of hyperbilirubinemia were urinary tract infection, ABO incompatibility, hypothyroidism and glucose-6-phosphate dehydrogenase deficiency in 14%, 5%, 6% and 5% of neonates, respectively. Moreover, unknown etiologies, such as breastfeeding, were detected in 70% of the studied infants. Conclusion: According to the results of this study, determining the main causes of prolonged unconjugated hyperbilirubinemia in neonates is of paramount importance. In the majority of cases, neonatal hyperbilirubinemia is associated with physiological factors, such as breastfeeding.

    2006-01-01

    Imaging of the central nervous system is one of the major tasks of Paediatric Radiology, particularly in newborns, who present with a variety of conditions that need more or less urgent imaging. Imaging is usually performed primarily by bedside US, in rare cases supplemented by a skull or spine radiograph. For more detailed information and preoperatively, MRI has become the neuroimaging tool. Thus, CT today is only used for acute trauma assessment, for assessment of potential cerebral calcifications or when MRI is not available. In cases with vascular anomalies or unsuccessful punctures, image guided interventions (embolisation) or image guidance for access (lumbar puncture, puncture of skull collections ...) may become necessary. This article tries to give a brief overview on the common disease entities, their typical imaging features in the major modalities applied and the implications of imaging potential for indication and choice of imaging method. In general, acute assessment may become everywhere and major features of important diseases should be recognised not to miss conditions which need urgent treatment or referral to a dedicated paediatric unit. Many other conditions will only be seen at centres with a dedicated neonatal care unit and dedicated paediatric radiologist who then also will be able to provide proper imaging with adapted protocols and methods for these partially severely sick babies. As these specific features and adapted capabilities as well as dedicated training and clinical experience are necessary for providing best results and proper handling in neonates, many neonatal conditions will not be imaged at a peripheral site, but primarily should be referred to a paediatric (radiology) centre

    Full Text Available Abstract Foetal/neonatal alloimmune thrombocytopaenia (NAIT results from maternal alloimmunisation against foetal platelet antigens inherited from the father and different from those present in the mother, and usually presents as a severe isolated thrombocytopaenia in otherwise healthy newborns. The incidence has been estimated at 1/800 to 1/1 000 live births. NAIT has been considered to be the platelet counterpart of Rh Haemolytic Disease of the Newborn (RHD. Unlike RHD, NAIT can occur during a first pregnancy. The spectrum of the disease may range from sub-clinical moderate thrombocytopaenia to life-threatening bleeding in the neonatal period. Mildly affected infants may be asymptomatic. In those with severe thrombocytopaenia, the most common presentations are petechiae, purpura or cephalohaematoma at birth, associated with major risk of intracranial haemorrhage (up to 20% of reported cases, which leads to death or neurological sequelae. Alloimmune thrombocytopaenia is more often unexpected and is usually diagnosed after birth. Once suspected, the diagnosis is confirmed by demonstration of maternal antiplatelet alloantibodies directed against a paternal antigen inherited by the foetus/neonate. Post-natal management involves transfusion of platelets devoid of this antigen, and should not be delayed by biological confirmation of the diagnosis (once the diagnosis is suspected, especially in case of severe thrombocytopaenia. Prompt diagnosis and treatment are essential to reduce the chances of death and disability due to haemorrhage. Due to the high rate of recurrence and increased severity of the foetal thrombocytopaenia in successive pregnancies, antenatal therapy should be offered. However, management of high-risk pregnancies is still a matter of discussion.

    Herpes simplex virus (HSV) 1 and HSV-2 infections are highly prevalent worldwide and are characterized by establishing lifelong infection with periods of latency interspersed with periodic episodes of reactivation. Acquisition of HSV by an infant during the peripartum or postpartum period results in neonatal HSV disease, a rare but significant infection that can be associated with severe morbidity and mortality, especially if there is dissemination or central nervous system involvement. Diagnostic and therapeutic advances have led to improvements in mortality and, to a lesser extent, neurodevelopmental outcomes, but room exists for further improvement. Copyright © 2015 Elsevier Inc.

    Past studies have clearly shown the existence of a spectrum of endometrial progesterone responses in neonatal endometrium, varying from proliferation to full decidualization with menstrual-like shedding. The bleedings represent, similar to what occurs in adult menstruation, a progesterone withdrawal bleeding. Today, the bleeding is completely neglected and considered an uneventful episode of no clinical significance. Yet clinical studies have linked the risk of bleeding to a series of events indicating fetal distress. The potential link between the progesterone response and major adolescent disorders requires to be investigated by prospective studies. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    2014-09-01

    The management of infants born with myelomeningocele depends on understanding how their bladder stores and empties urine. Storage at low pressure with effective emptying periodically throughout the day is the goal. Intervention is designed to impact on one or both of these processes so that infants can remain infection-free and at the same time allow for appropriate renal growth over time. Urodynamic evaluation plays an important role, so that neonates can be stratified according to their risk. Most patients require intermittent catheterization and pharmacotherapy to achieve these goals at some point in their lives. Copyright © 2014 Elsevier Inc. All rights reserved.

    Twenty-four Staphylococcus species or subspecies were examined for their susceptibilities to the fluoroquinolone fleroxacin (Ro 23-6240) by disk diffusion (5-micrograms disk) and by agar dilution for the determination of MICs. Resistant strains were further tested for their susceptibilities to oxacillin and the fluoroquinolone ciprofloxacin. Reference strains of the novobiocin-resistant species (Staphylococcus saprophyticus, Staphylococcus cohnii, Staphylococcus xylosus, Staphylococcus arlettae, and Staphylococcus gallinarum) had an intrinsic intermediate susceptibility (MIC, 4 micrograms/ml) to fleroxacin. Fleroxacin resistance was not observed in the reference strains of the novobiocin-susceptible species (MIC, 0.5 to 2.0 micrograms/ml). Clinical isolates of coagulase-negative species were generally less susceptible to fleroxacin than were reference strains. Seven percent of the Staphylococcus epidermidis clinical strains were resistant (MIC, greater than or equal to 8 micrograms/ml) to fleroxacin. Of these strains, 77% were resistant to oxacillin and 50% were resistant to ciprofloxacin. Thirty-four percent of the Staphylococcus haemolyticus clinical strains were resistant to fleroxacin, and 9% had intermediate susceptibility. Of the resistant strains, 95% were resistant to oxacillin and 77% were resistant to ciprofloxacin, while 23% had intermediate susceptibility to ciprofloxacin. Fleroxacin is an effective antimicrobial agent against most staphylococci. PMID:1759838

    Aman, I.; Hassan, K.A.; Ahmad, T.M.

    2004-01-01

    Objective: To determine the number of cases and manifestations of thrombocytopenia in sick neonates. Subjects and Methods: A total of 365 neonates from 0-28 days of age admitted with different clinical problems irrespective of birth weight and gestational age were evaluated for thrombocytopenia. These neonates were categorized into five different groups (A-E), which were of neonatal infections, asphyxia neonatorum, preterm and smallness for gestational age, jaundice and miscellaneous respectively. Results: Out of 365 cases, 88 were found to have thrombocytopenia (platelet counts < 150,000 per mm/sup 3/) which was 24.1% of the total. In group A (neonatal infections), out of 152 neonates, 62 had low platelet counts (40.78%). In group B (neonatal asphyxia), out of 90 only 11 had thrombocytopenia (12.2%). In group C (preterm and small for gestational age), out of 60 cases only 9 had thrombocytopenia. In group D (jaundice), all 33 cases had normal platelet counts. In group E (miscellaneous), out of 30 cases only 6 had thrombocytopenia. The common manifestations in thrombocytopenic babies were petechiae and bruises followed by gastrointestinal hemorrhages. The percentage of manifest thrombocytopenia cases was 56.8% and of occult thrombocytopenia 43.1 %. Conclusion: The leading causes of thrombocytopenia in sick neonates are infections, asphyxia, complicated pre- maturity and smallness for gestational age. Apart from the platelet counts the bleeding mainfestations also depend upon the underlying ailments. (author)

The main concern is about methicillin-resistant isolates (MRSA, which are usually limited to hospitals. In recent years, community associated or acquired MRSA infections (CA-MRSA have been frequently reported and emerged in the world. Some phenotypic and genotypic characteristics are distinct between hospital and community infection. Currently, there is reduced sensibility profile to different antimicrobials, reason why it is necessary to issue an alert to healthcare professionals, dermatologists in particular, about the importance of knowing the differences between the infections, preventing wrong and unsuccessful empirical therapy.

    To ascertain and compare microbial growth pattern in blood culture of septic neonates who were either totally breast or formula fed. Study Design: Cross sectional study. Place and Duration of Study: The Children's Hospital Lahore, Pakistan from Feb 2012 to Dec 2012. Methodology: All clinically septic neonates, who were either exclusively breast fed or formula fed, were enrolled in the study. They were divided into two groups and studied for the type of organisms grown on blood culture. Group-A were breast fed and group-B were formula fed. Neonates who were blood culture negative or had growth of multiple organisms or had incomplete data or who died / left against medical advice before completing the required data or babies receiving milk feeding from multiple sources or no feeding at all were excluded. BACTEC technique was used for obtaining bacterial growth. SPSS version 19 was used for statistical analysis. Results: A total of 380 clinically septic neonates were enrolled. Each group consisted of 190 subjects. Incidence of culture positive sepsis in breast fed and in formula fed was 6.7% and 15.7% respectively (p-value = 0.0001). Overall, gram-negative organisms constituted the majority (16.1%). Thirty seven percent cultures grew coagulase negative Staphylococcus (CoNS) followed by Klebsiella spp (23.4%). In group A, gram-negative and gram-positive organisms were equally distributed whilst in group-B, gram-negative organisms were three times more frequent than gram-positive organisms. Predominant pattern of organisms was also different in the two groups. In group-A, CoNS was predominant while in group-B, Klebsiella spp. was most frequent. Conclusion: Culture positive sepsis is more than two times greater in formula fed babies and is caused predominantly by gram-negative organisms whilst in breast fed babies, CoNS is the commonest organism.

    The principles of clinical pharmacology also apply to neonates, but their characteristics warrant a tailored approach. We focus on aspects of both developmental pharmacokinetics (concentration/time relationship) and developmental pharmacodynamics (concentration/effect relationship) in neonates. We hereby aimed to link concepts used in clinical pharmacology with compound-specific observations (anti-epileptics, analgosedatives) in the field of neonatal neurology. Although in part anecdotal, we subsequently illustrate the relevance of developmental pharmacology in the field of neonatal neurology by a specific intervention (e.g. whole body cooling), specific clinical presentations (e.g. short and long term outcome following fetal exposure to antidepressive agents, the development of new biomarkers for fetal alcohol syndrome) and specific clinical needs (e.g. analgosedation in neonates, excitocytosis versus neuro-apoptosis/impaired synaptogenesis).

    2016-08-03

    A 1-week-old infant was brought to a regional hospital with a history of recurrent seizures following lower abdominal septic skin infection. She was found to have neonatal tetanus, and a spatula test was positive. The tetanus infection was associated with a superficial skin infection, common in neonates. Treatment included sedatives (diazepam, chlorpromazine, phenobarbitone and morphine), muscle relaxants, antibiotics and ventilation in the neonatal intensive care unit. Intrathecal and intramuscular immunoglobulin were given, and the wound was treated. The infant recovered, with no seizures by the 16th day from admission, and was off the ventilator by the 18th day. This was shorter than the usual 3 - 4 weeks for neonates with tetanus at the hospital. The question arises whether tetanus immunisation should be considered in infants with skin infections, which frequently occur in the neonatal period.

    Fifteen patients with persistent neonatal jaundice were evaluated by sonography and radionuclide scintigraphy. The sonographic features of both neonatal hepatitis and biliary atresia are nonspecific. Hepatobiliary scintigraphy after phenobarbital pretreatment in patients with neonatal hepatitis demonstrates normal hepatic extraction and delayed tracer excretion into the gastrointestinal tract. If there is neonatal hepatitis with severe hepatocellular damage, the hepatic extraction of tracer activity is decreased and excretion may be delayed or absent. Patients under 3 months of age with biliary atresia have normal hepatic extraction of tracer with no excretion into the gastrointestinal tract. Sonography in patients with a choledochal cyst shows a cystic mass in the porta hepatis with associated bile-duct dilatation. Hepatobiliary scintigraphy confirms that the choledochal cyst communicates with the biliary system. Initial sonography demonstrates hepatobiliary anatomy; subsequent phenobarbital-enhanced radionuclide scintigraphy determines hepatobiliary function. An expedient diagnostic approach is recommended for the evaluation of persistent neonatal jaundice

    Full Text Available Abstract Background Analgesia for neonatal circumcision was recently advocated for every male infant, and its use is considered essential by the American Academy of Pediatrics. We compared the post-operative analgesic quality of bupivacaine to that of lidocaine for achieving dorsal penile nerve block (DPNB when performing neonatal circumcision. Methods Data were obtained from 38 neonates following neonatal circumcision. The infants had received DPNB analgesia with either lidocaine or bupivacaine. The outcome variable was the administration by the parents of acetaminophen during the ensuing 24 hours. Results Seventeen infants received lidocaine and 19 received bupivacaine DPNB. Ten infants in the lidocaine group (59% were given acetaminophen following circumcision compared to only 3 (16% in the bupivacaine group (P 2 = 20.6; P = 0.006. Conclusion DPNB with bupivacaine for neonatal circumcision apparently confers better analgesia than lidocaine as judged by the requirement of acetaminophen over the ensuing 24-hour period.

    The aim of our study was to analyze clinical and biological characteristics of immunocompromised patients with staphylococcal sepsis and to compare with the same data in non-immunocompromised patients. The diagnosis of sepsis was made based on Bone criteria. MiniAPI system ID 32 STAPH was used for identification and antibiotic susceptibility was assessed by ATB STAPH method and by E-test for oxacillin and vancomycin. Among the 147 patients with Staphylococcus aureus sepsis--66.67% had concomitant immunosuppressive conditions (diabetes mellitus, liver diseases, renal failure, corticotherapy, etc). We have found a significant correlation between the immunosuppressed status and MRSA (methicillin-resistant Staphylococcus aureus) involvement (p = 0.0018) and also, between this group of patients and treatment failure (p = 0.0012). Because of the high rate of MRSA involvement in systemic infections in the Eastern region of Romania first intention treatment of patients with staphylococcal infections and conditions of immunosuppression must include antibiotics effective against methicillin-resistant strains.

Due to the frequent need for resuscitation at birth, it is vital to have evidence-based care guidelines and to provide effective neonatal resuscitation training. Every five years, the International Liaison Committee on Resuscitation (ILCOR reviews the science of neonatal resuscitation. In the US, the American Heart Association (AHA develops treatment guidelines based on the ILCOR science review, and the Neonatal Resuscitation Program (NRP translates the AHA guidelines into an educational curriculum. In this report, we review recent advances in neonatal resuscitation training and practice. We begin with a review of the new 7th edition NRP training curriculum. Then, we examine key changes to the 2015 AHA neonatal resuscitation guidelines. The four components of the NRP curriculum reviewed here include eSim®, Performance Skills Stations, Integrated Skills Station, and Simulation and Debriefing. The key changes to the AHA neonatal resuscitation guidelines reviewed include initial steps of newborn care, positive-pressure ventilation, endotracheal intubation and use of laryngeal mask, chest compressions, medications, resuscitation of preterm newborns, and ethics and end-of-life care. We hope this report provides a succinct review of recent advances in neonatal resuscitation.

    Full Text Available The design of a neonatal monitor for medical training purposes is hereby presented. In order to do that, the following main vital signs were modeled and simulated: ECG, pulse, blood pressure, CO2 level, among others. The signals were integrated to a graphic interface that generates different scenarios showing signals of patients with or without pathologies. Simulated signals were validated against real ones and, in general, the error is less than 5%; in addition, the neonatal monitor was assessed by 16 specialists; those doctors stated that simulated signals are of "excellent quality", "truthful" and that the interface is "user friendly".Se presenta el desarrollo de un monitor neonatal orientado al entrenamiento médico.

    Lung disease represents one of the most life-threatening conditions in prematurely born children. In the evaluation of the neonatal chest, the primary and most important diagnostic study is therefore the chest radiograph. Since prematurely born children are very sensitive to radiation, those radiographs may lead to a significant radiation detriment. Hence, knowledge of the patient dose is necessary to justify the exposures. A study to assess the patient doses was started at the neonatal intensive care unit (NICU) of the Univ. Hospital in Leuven. Between September 2004 and September 2005, prematurely born babies underwent on average 10 X-ray examinations in the NICU. In this sample, the maximum was 78 X-ray examinations. For chest radiographs, the median entrance skin dose was 34 μGy and the median dose area product was 7.1 mGy.cm 2 . By means of conversion coefficients, the measured values were converted to organ doses. Organ doses were calculated for three different weight classes: extremely low birth weight infants ( 2500 g). The doses to the lungs for a single chest radiograph for infants with extremely low birth weights, low birth weights and normal birth weights were 24, 25 and 32 μGy, respectively. (authors)

    1. We have reviewed 34 cases of neonatal intracranial hemorrhages (perinatal onset, 23 mature and 11 premature infants) experienced in 10-year period from 1971 to 1980, with special reference to gestational age, birth weight, type of delivery, presence or absence of asphyxia, symptoms and cause of death. 2. Regarding 9 autopsied cases and 7 cases diagnosed by CT-scan, 10 mature infants composed of 3 subarachnoid hemorrhages, 2 intraventricular hemorrhages, 2 subdural hematomas, 2 intracerebral and 1 subependymal hemorrhage; 6 premature infants consisted of 4 subependymal hemorrhages with ventricular rupture and 2 subarachnoid hemorrhages. Most of them presented with respiratory distress, vomiting and convulsive seizures which developed within 5 days after birth. 3. Poor outcome including death amounted 49% of mature and 63% of premature infants. Along with degree of intracranial hematoma, prematurity and pulmonary complication were felt to be important prognostic factors. 4. Introduction of CT-scan led to prompt diagnosis and treatment, thus lowering mortality rate of neonatal intracranial hemorrhages. (author)

    Respiratory syncytial virus (RSV) is the leading cause of bronchiolitis in infants. Palivizumab is an immunoprophylactic agent for RSV prevention in preterm infants and those with neonatal chronic lung disease. This study examines its use across neonatal units in Ireland. A questionnaire was administered to one Consultant Neonatologist or Paediatrician in each of the 20 maternity centres in Ireland about their guidelines for Palivizumab administration. There is variation in administration of Palivizumab with little consistency found between protocols reported in terms of age and presence of chronic lung disease. Ten centres have in house protocols, 3 centres use the American Academy of Paediatrics (AAP) guidelines, 2 centres prefer the UK Joint Committee on Vaccination and Immunisation (JCVI) guidelines and 3 centres do not have a set protocol. Four participants felt its use has impacted on hospital admissions and 61% believe its use is cost effective. The budgetary implication for immunoprophylaxis with Palivizumab in Ireland is estimated at 1.5 to 2 million euros annually. Given current pharmacoeconomic constraints there is a need to implement a national protocol on RSV immunoprophylaxis.

    Neonatal transport teams comprise multidisciplinary health care providers who are skilled in patient care, communication and customer service, and equipment mechanics. They are extensively trained in resuscitation and stabilization, preparing for accelerating care, and their focus is preservation of life. In any situation focused on caring for critically ill patients, ethical issues and questions may arise. For instance, is it compassionate and/or cost-effective to separate mothers and infants when continuing/accelerating care is futile, and when and how should care be redirected from acute and lifesaving care to comfort care and bereavement support for the family? The knowledge and skills required to address such situations and communicate and participate in a redirection of care may not be adequately emphasized in the preparation of the professionals responsible for stabilizing and transporting critically ill newborns. This article raises issues relating to transport and redirecting care such as eligibility for transport, parental request and consent, separation of mothers and infants, palliative and bereavement care, ethical considerations, competitive transport environment, and customer service. A shared mental model is essential. The focus of this article is not to provide answers to all of these issues, but to highlight the complexity of the topic of redirecting treatment during neonatal transport. Redirecting treatment needs to be discussed, and health care professionals should be prepared during their transport team training. Each family and situation must be approached individually, with the acceptance that there will always be more questions than answers.

    Advances in cardiology, surgical techniques, postoperative care, and medications have improved the chances of long-term survival of the neonatal and pediatric patient with complex congenital cardiac anomalies. Rather than undergoing palliative repair, these children are now frequently taken to the operating room for complete repair. As complete repair becomes the norm, collaborative management and a thorough understanding of the pre and postoperative medications used become essential to the care of these patients. The nurse's ability to understand preop, postop, and management medications is enhanced by an understanding of the principles of cardiac anatomy and physiology, as well as developmental changes in cardiac function. All of these are reviewed. In addition, since the safe and effective administration of these drugs depends on the pediatric intensive care unit (PICU) and neonatal intensive care unit (NICU) nurse's thorough knowledge of these medications and their effects on the cardiovascular system, a brief review of these medications is presented. While new technology and techniques are improving survival rates for children with congenital heart anomalies, it is the postoperative care that these children receive that enhances the patient's survival even more.

    Twenty-seven Nigerian infants with osteomyelitis are presented during the first 28 days of life to highlight the severity of the clinical manifestations and the radiological features of this infection. The clinical signs include limitation of movement of the extremities involved and localised swelling. Severe constitutional changes such as fever (>39/sup 0/C) and abdominal distension were common. This contrasts with results from North America and Europe which emphasize the paucity of clinical signs despite involvement of multiple sites. Multiple site involvement was encountered in only eight cases. Staphylococcus aureus, proteus mirabilis and candida albicans were the main pathogens isolated. The long bones were more frequently affected. Aggressive bone destruction was a constant radiological finding peculiar to Staphylococcal osteomyelitis while the formation of Sequestrum, are rare occurrence in the newborn, was present in six patients. The mortality rate was 7.4% and the morbidity rate was equally low.

    Full Text Available Background: Neonatal pain management has received increasing attention over the past four decades. Research into the effects of neonatal pain emphasises the professional, ethical and moral obligations of staff to manage pain for positive patient outcomes. However, evaluation studies continuously report evidence of inadequate neonate pain management and a gap between theory and practice. Objective: This study reviewed current practice in neonatal pain management to describe the knowledge, attitudes and practices of nurses and doctors regarding pain management for neonates in two academic hospitals. Method: A non-experimental, prospective quantitative survey, the modified Infant Pain Questionnaire, was used to collect data from 150 nurses and doctors working in the neonatal wards of two academic hospitals in central Gauteng. Results: The response rate was 35.33% (n = 53, most respondents being professional nurses (88.68%; n = 47 working in neonatal intensive care units (80.77%; n = 42; 24 (45.28% had less than 5 years’ and 29 respondents 6 or more years’ working experience in neonatal care. A review of pain management in the study setting indicated a preference for pharmacological interventions to relieve moderate to severe pain. An association (p < 0.05 was found between pain ratings on 5 procedures and frequency of administration of pharmacological pain management. Two-thirds of respondents (64% reported that there were no pain management guidelines in the neonatal wards in which they worked. Conclusion: The interventions to manage moderate neonatal pain are in line with international guidelines. However, neonatal pain management may not occur systematically based on prior assessment of neonatal pain, choice of most appropriate intervention and evaluation. This study recommends implementation of a guideline to standardise practice and ensure consistent and adequate pain management in neonates.

    Full Text Available BACKGROUND Of the 130 million babies born worldwide each year, 26 million are born in India alone. Four million babies die with in first 30 days of birth and another four million are stillborn. Newborn mortality represents 40% of all deaths of children less than five years of age. Of the four million deaths each year, nearly 98% occur in developing countries. Globally major causes of neonatal deaths are due to preterm births (28%, sepsis or pneumonia (26% and birth asphyxia (23%. Neonatal sepsis is one of the commonest causes of neonatal deaths in the developing world accounting to 30-50% of all neonatal deaths per year. The present study is intended to help the practising paediatrician to accurately diagnose the sepsis early using the specific laboratory tests and avert the progression of the disease. METHODS It is an observational cross-sectional study in NICU, Mahatma Gandhi Memorial Hospital. The study was conducted in the period November 2013 to October 2014. After admission, detailed history and thorough clinical examination was done. Required data was entered in a pre-set proforma and statistical analysis was done. Blood culture was sent. Bacterial culture and sensitivity was checked. RESULTS In proven sepsis, 50.25% were Gram-positive, 43.65% were Gram-negative and 6.09% were fungal sepsis Candida. Klebsiella (32.48% was the most common organism followed by Coagulase positive Staphylococcus (25.38% and CONS (20.81%. In this study, Gram-negative sepsis was more common in preterm and Gram-positive sepsis was more common in term neonates. Early onset sepsis was the common presentation of proven sepsis, Klebsiella was common organism causing EOS. Whereas CONS was commonest causing late onset sepsis. Among Gram-negative organisms, 58.1% and 27.9% were resistant to cefotaxime and ampicillin+sulbactam respectively. Among Gram-positive isolates, 35% and 22% were resistant to cefotaxime and ampicillin+sulbactam respectively. Klebsiella, most

    Full Text Available La resistencia a meticilina en el género Staphylococcus spp es un problema creciente en el ámbito mundial. La producción de una PBP alterada (PBP2a con baja afinidad a betalactámicos, mediada por el gen mec A, es la responsable de esta resistencia. Mientras que los Staphylococcus spp todavía permanecen sensibles a vancomicina, algunos Enterococcus spp han adquirido la capacidad de neutralizar esta droga. En nuestro país no se conocen datos actualizados sobre la tasa de infección por S. aureus meticilina resistente (SAMR, ni sobre la circulación de este germen en la comunidad, tampoco existen reportes de Enterococcus spp vancomicina resistente (EVR. En este estudio fueron analizadas 774 cepas, colectadas en hospitales del país. Se determinó el mecanismo de resistencia utilizando métodos sugeridos por las guías NCCLS. El 9.3 % (23 de los S. aureus aislados en los hospitales y 4.0% (7 S. aureus aislados en la comunidad, fueron SAMR, portadores del gen mec A, el 69.9 % (72 de Staphylococcus coagulasa negativo, fueron resistentes a oxacilina. En la detección del Enterococcus spp vancomicina resistente (EVR, se encontró una cepa portadora de este fenotipo. Nuestros resultados revelan que en nuestro país los SAMR no son un problema en los hospitales, ni en el ambiente comunitario, a pesar de que se reporta por primera vez la circulación de estos en la comunidad y la circulación de EVR en el ambiente hospitalario, su frecuencia es muy baja lo que refleja los avances obtenidos en la aplicación de políticas encaminadas a racionalizar el uso y consumo de antibióticos.Resistance to methicilline in Staphylococcus spp genus is a growing problem worldwide. The production of an altered penicillin-fixing protein with low mecA gen-mediated affinity to beta-lactams is responsible for this resistance. Although Staphylococcus spp still remain susceptible to vancomycin, some Enterococcus spp have acquired the capacity of neutralizing this drug. In

Objetivo: exponer los resultados de nuestra experiencia en el tratamiento de recién nacidos con perforación gástrica, y revisar el estado actual del conocimiento sobre esta nosología. Métodos: se realizó una investigación descriptiva, retrospectiva, con la totalidad de los recién nacidos ingresados en la sala de neonatología quirúrgica del Hospital Pediátrico Universitario "William Soler", diagnosticados con perforación gástrica, durante el período comprendido entre enero de 1990 y diciembre de 2010. Resultados: se trataron 8 pacientes, de los cuales 3 se consideraron como idiopáticos. El neumoperitoneo estuvo presente en la totalidad de los pacientes. El fundus gástrico y la cara anterior del órgano constituyeron los sitios más frecuentemente afectados. Por su lado, la prematuridad no guardó una clara relación con la ocurrencia de la perforación. En la mayoría de los pacientes se realizó una reparación primaria de la perforación sin gastrostomía. La mortalidad general en el estudio fue de un 62 %, y fue la peritonitis la complicación más frecuente. Conclusiones: la perforación gástrica neonatal constituye una entidad altamente letal, en la cual las distintas alternativas de tratamiento quirúrgico no son, en definitiva, por sí solas, la solución para lograr una adecuada sobrevida.

    This paper describes our leading experience in the clinical application of laser in the treatment of neonatal jaundice. Currently, the irradiation of jaundiced infants during neonatal life to fluorescent light is the most common treatment of neonatal hyperbilirubinemia. The authors have investigated the photodegradation of bilirubin by laser in vitro and in Gunn rats before embarking on its clinical application in the treatment of jaundice in the new born child. This work was done to study the theraputic effect of laser compared to the currently used phototherapy in the treatment of neonatal jaundice. We selected 16 full term neonates with jaundice to be the subject of this study. The neonates of the study were devided into two groups. The first group was treated with continuous phototherapy . The second group recieved photoradiation therapy with gas laser The laser used was a CW argon-ion laser tuned to oscillate at 488.0 nm wavelength. This wavelength selection was based on our previous studies on the effect of laser irradiation of Gunn rats at different wavelengths. Comparison of the results of both methods of treatment will be reported in detail. The advantages and limitations of laser photoradiation therapy for neonatal jaundice will be discussed.

    Full Text Available The objectives of the study were to evaluate the presence/production of beta-lactamases by both phenotypic and genotypic methods, verify whether results are dependent of bacteria type (Staphylococcus aureus versus coagulase-negative Staphylococcus - CNS and verify the agreement between tests. A total of 200 bacteria samples from 21 different herds were enrolled, being 100 CNS and 100 S. aureus. Beta-lactamase presence/detection was performed by different tests (PCR, clover leaf test - CLT, Nitrocefin disk, and in vitro resistance to penicillin. Results of all tests were not dependent of bacteria type (CNS or S. aureus. Several S. aureus beta-lactamase producing isolates were from the same herd. Phenotypic tests excluding in vitro resistance to penicillin showed a strong association measured by the kappa coefficient for both bacteria species. Nitrocefin and CLT are more reliable tests for detecting beta-lactamase production in staphylococci.

    Antibiotics are often used in neonates despite the absence of relevant dosing information in drug labels. For neonatal dosing, clinicians must extrapolate data from studies for adults and older children, who have strikingly different physiologies. As a result, dosing extrapolation can lead to increased toxicity or efficacy failures in neonates. Driven by these differences and recent legislation mandating the study of drugs in children and neonates, an increasing number of pharmacokinetic studies of antibiotics are being performed in neonates. These studies have led to new dosing recommendations with particular consideration for neonate body size and maturation. Herein, we highlight the available pharmacokinetic data for commonly used systemic antibiotics in neonates.

    Staphylococcus sp. is one of the most dangerous bacteria that could cause food poisoning. It is a pathogenic bacterium which is able to produce enterotoxin in foods. Milk is an ideal growth medium for Staphylococcus sp., that may cause problem if it is to be consumed, especially by infant. It is the objective of this research to detect the presence of Staphylococcus sp. in powdered infant milk. As many as 14 samples obtained from market were used as samples for bacterial isolation. The isolation were done by employing enrichment step on BHI-broth, continued with Baird-Parker Agar which will produce a typical colony. It is then picked and grown on Mannitol Salt Agar, and gram staining, coagulase assay, and fermentation tests. The confirmation step was done by using API-Staph which gives the identification of Staphylococcus hemoliticus, Staphylococcus aureus and Staphylococcus epidermidis, with a percentage of identity ranging from 65.9-97.7%. Two isolates with the highest identification similarity values were then picked for molecular detection. A PCR primer pair targeting gene coding for enterotoxin A was used, and it gives positive result for the two isolates being tested. It is then concluded that the two isolates belong to Staphylococcus sp., and further research need to be done to correctly identify these isolates.

O objetivo deste estudo foi verificar a presença de Staphylococcus spp. na cavidade bucal e nas bolsas periodontais de pacientes com periodontite crônica; identificar as cepas isoladas; verificar a relação entre a presença de Staphylococcus spp. na cavidade bucal e presença de bolsa periodontal. Participaram deste estudo 88 pacientes, entre 25 e 60 anos de idade e apresentando periodontite crônica, com pelo menos dois sítios com profundidade de sondagem maior ou igual a 5mm. Após anamnese e exame clínico periodontal foram feitas coletas de material da bolsa periodontal com cones de papel e da cavidade bucal por meio de bochechos. Do total de pacientes 37,50% apresentaram Staphylococcus spp. na bolsa periodontal e 61,36% na cavidade bucal, sendo que 27,27% apresentaram a bactéria nos 2 sítios. S. epidermidis foi a espécie mais prevalente para bolsa periodontal (15,9% e cavidade bucal (27,27%. Não houve diferença estatística significante quanto à presença desses microrganismos entre as faixas etárias e aumento da profundidade de sondagem. A presença de bactérias oportunistas na cavidade bucal pode representar dificuldades para a manutenção do tratamento periodontal.

    Staphylococcus intermedius group (SIG) bacteria can colonise the nares of some animals but are also emerging pathogens in humans and animals. To analyse SIG nasal carriage in healthy donkeys destined for food consumption in Tunisia and to characterise recovered isolates. Nasal swabs from 100 healthy donkeys were tested for SIG recovery, and isolates were identified by biochemical and molecular methods. Antimicrobial susceptibility of isolates was tested and detection of antimicrobial resistance and virulence genes was performed. Isolates were typed at the clonal level by multilocus sequence typing and SmaI pulsed-field gel electrophoresis. Staphylococcus delphini and Staphylococcus pseudintermedius (included in SIG) were obtained in 19% and 2% of the tested samples, respectively, and one isolate per sample was characterised. All isolates were meticillin susceptible and mecA negative. Most S. delphini and S. pseudintermedius isolates showed susceptibility to all antimicrobials tested, with the exception of 2 isolates resistant to tetracycline (tet(M) gene) or fusidic acid. The following toxin genes were identified (percentage of isolates): lukS-I (100%), lukF-I (9.5%), siet (100%), se-int (90%), seccanine (19%) and expA (9.5%). Thirteen different pulsed-field gel electrophoresis profiles were identified among the 21 SIG isolates. Additionally, the following 9 different sequence types (STs) were detected by multilocus sequence typing, 6 of them new: ST219 (6 isolates), ST12 (5 isolates), ST220 (3 isolates), ST13, ST50, ST193, ST196, ST218 and ST221 (one isolate each). Staphylococcus delphini and S. pseudintermedius are common nasal colonisers of donkeys, generally susceptible to the antimicrobials tested; nevertheless, these SIG isolates contain virulence genes, including the recently described exfoliative gene (expA) and several enterotoxin genes, with potential implications for public health. This is the first description of S. delphini in Tunisia. The

    Advances in neonatal intensive care, total parenteral nutrition and improvements in technology have led to a greatly improved outcome of neonatal surgery in developed countries. In many parts of sub-Saharan Africa, however, neonatal surgery continues to pose wide-ranging challenges. Delivery outside hospital, delayed referral, poor transportation, and lack of appropriate personnel and facilities continue to contribute to increased morbidity and mortality in neonates, particularly under emergency situations. Antenatal supervision and hospital delivery needs to be encouraged in our communities. Adequate attention needs to be paid to providing appropriate facilities for neonatal transport and support and training of appropriate staff for neonatal surgery. Neonates with surgical problems should be adequately resuscitated before referral where necessary but surgery should not be unduly delayed. Major neonatal surgery should as much as possible be performed by those trained to operate on neonates. Appropriate research and international collaboration is necessary to improve neonatal surgical care in the environment.

    Full Text Available Abstract Background Neonatal mortality accounts for almost 40 per cent of under-five child mortality, globally. An understanding of the factors related to neonatal mortality is important to guide the development of focused and evidence-based health interventions to prevent neonatal deaths. This study aimed to identify the determinants of neonatal mortality in Indonesia, for a nationally representative sample of births from 1997 to 2002. Methods The data source for the analysis was the 2002–2003 Indonesia Demographic and Health Survey from which survival information of 15,952 singleton live-born infants born between 1997 and 2002 was examined. Multilevel logistic regression using a hierarchical approach was performed to analyze the factors associated with neonatal deaths, using community, socio-economic status and proximate determinants. Results At the community level, the odds of neonatal death was significantly higher for infants from East Java (OR = 5.01, p = 0.00, and for North, Central and Southeast Sulawesi and Gorontalo combined (OR = 3.17, p = 0.03 compared to the lowest neonatal mortality regions of Bali, South Sulawesi and Jambi provinces. A progressive reduction in the odds was found as the percentage of deliveries assisted by trained delivery attendants in the cluster increased. The odds of neonatal death were higher for infants born to both mother and father who were employed (OR = 1.84, p = 0.00 and for infants born to father who were unemployed (OR = 2.99, p = 0.02.

    2016-10-01

    Intrathoracic stomach is a rare and serious congenital abnormality. The anomaly may be complicated by gastric volvulus and can lead to ischemic gastric infarction in the neonate. If diagnosed antenatally, neonatal management can be planned in advance so as to reduce morbidity. This anomaly must be differentiated from the more common congenital diaphragmatic hernia, as associated pulmonary hypoplasia is common in the latter and rare with gastric herniation. We report a case of intrathoracic stomach in a neonate without volvulus, fortunately a rare entity which was managed operatively, and the child has been under regular follow-up.

    The aims of this study were to identify the source and the transmission pathway for a Staphylococcal Scalded Skin Syndrome (SSSS) outbreak in a maternity setting in Italy over 2 months, during 2014; to implement appropriate control measures in order to prevent the epidemic spread within the maternity ward; and to identify the Methicillin-Resistant Staphylococcus aureus (MRSA) epidemic clone. Epidemiological and microbiological investigations, based on phenotyping and genotyping methods, were performed. All neonates involved in the outbreak underwent clinical and microbiological investigations to detect the cause of illness. Parents and healthcare workers were screened for Staphylococcus aureus to identify asymptomatic carriers. The SSSS outbreak was due to the cross-transmission of a rare clone of ST5-CA-MRSA-SCCmecV-spa type t311, exfoliative toxin A-producer, isolated from three neonates, one mother (from her nose and from dermatological lesions due to pre-existing hand eczema) and from a nurse (colonized in her nose by this microorganism). The epidemiological and microbiological investigation confirmed these as two potential carriers. A rapid containment of these infections was obtained only after implementation of robust swabbing of mothers and healthcare workers. The use of molecular methodologies for typing was able to identify all carriers and to trace the transmission.

    2008-01-01

    A total 355 of Staphylococcus cohnii isolates from hospital environment, patients (newborns), medical staff and from non-hospital environment were tested for hemolytic activity. Ninety-one % of S. cohnii ssp. cohnii and 74.5 % S. cohnii ssp. urealyticus strains exhibited hemolysis synergistic to S. aureus ATCC 25923 strain. Crude preparations of hemolysins of both bacterial subspecies presented delta-hemolysin, but not alpha- and beta-toxin activity. Highly pure hemolysins were obtained by semipreparative SDS-PAGE or by organic solvent extraction from the freeze-dried crude preparations. Native-PAGE and 2D-PAGE showed their high heterogeneity. Molar masses of single hemolysin units estimated by the Tris-Tricine-SDS-PAGE were calculated as 3.47 kDa for S. cohnii ssp. cohnii and 3.53 kDa for S. cohnii ssp. urealyticus.

    Full Text Available Necrotizing fasciitis is a life-threatening soft tissue infection that results in rapid local tissue destruction. Type 1 necrotizing fasciitis is characterized by polymicrobial, synergistic infections that are caused by non-Group A streptococci, aerobic and anaerobic organisms. Type 2 necrotizing fasciitis involves Group A Streptococcus (GAS with or without a coexisting staphylococcal infection. Here we provide the first report of necrotizing fasciitis jointly associated with the microbes Group B Streptococcus and Staphylococcus lugdunensis. S. lugdunensis is a commensal human skin bacterium known to cause often painful and prolonged skin and soft tissue infections. To our knowledge, however, this is the first case of Staph. lugdunensis-associated necrotizing fasciitis to be reported in the literature.

    In this case report the authors present an extremely low birth weight premature infant with neonatal brucellosis whose mother had been treated for brucellosis during pregnancy. Infant developed mild respiratory distress syndrome soon after birth. At 2nd wk of postnatal age findings of bronchopulmonary dysplasia were evident and she and her mother were diagnosed to have brucellosis at the same time. After commencement of antibrucellosis therapy and nonspesific treatment for bronchopulmonary dysplasia, infant was completely cured of the symptoms related to both brucellosis and bronchopulmonary dysplasia. The results of the present case and a review of the literature have let to conclude that Brucella might have role in development of prematurity and bronchoplumonary dysplasia. Since discovery of brucella bacilli in early periods of 20th century, fetotoxicity of brucella bacilli seems to increase gradually suggesting an increasing virulance of the bacilli or vanishing host defense of human beings.

    Various aspects of the thyroid function have been measured in 28 cases of neonatal hypothyroidism detected by means of the Quebec Screening Program for Metabolic Diseases. In all instances the T4 value in the blood of filter paper spot was below 2 SD of the mean of the day, averaging 0.39 +/- 0.04 ng/40 mul (mean +/- SEM) of eluted blood. The T4 value of a second similar sample averaged 0.22 +/- 0.04 ng/mul of eluted blood; this value was significantly lower than the first one. The serum T4 concentration was decreased in all the infants, whereas three of them had a normal serum TSH concentration. At least three groups of patients could be identified: (1) patients with primary thyroid failure, (2) those with secondary or tertiary hypothyrodism, and (3) those with abnormal synthesis of thyroid hormone.

As diferentes modalidades de alimentação do recém-nascido prematuro - especialmente para aqueles de muito baixo peso - e seu efeito protetor na diminuição de complicações (mormente as infecciosas foram analisadas. A utilização preferencial do leite materno na nutrição enteral, o controle das ofertas energético-protéicas, o início precoce da nutrição enteral mínima, a introdução precoce da alimentação parenteral - nas primeiras 24 horas - e a utilização dos imunonutrientes que tenham estudos suficientes para fundamentar sua indicação podem se constituir em boas diretrizes adjuvantes na prevenção da sepse neonatal e da enterocolite necrosante. Sem embargo, percebe-se a necessidade de mais estudos - preferencialmente multicêntricos, controlados e randomizados - para esclarecer o papel protetor da nutrição no RNPT, não somente na prevenção de infecções, mas também para auxiliar o desenvolvimento neural e a prevenção de consequências deletérias futuras.

    The aim of this study was to investigate the frequency and type of X ray examinations performed on neonates classified according to their birth weight in a neonatal intensive care unit (NICU). In this study, the radiology records of 2408 neonates who were admitted to the NICU of Oita Prefectural Hospital between January 1994 and September 1999 were investigated. This study revealed that the neonates with earlier gestational ages and lower birth weights required longer NICU stays and more frequent X ray examinations made using a mobile X ray unit. The average number of X ray examinations performed on neonates of less than 750 g birth weight was 26 films per neonate. In regard to computed tomography and fluoroscopy, no significant relationship was found between the birth weight and number of X rays. This study revealed that the entrance-surface dose per neonate was dependent upon the birth weight, while the maximum dose was not dependent upon the birth weight. The average neonatal dose in the NICU was predominantly from computed tomography and fluoroscopy. The individual dose varied widely among neonates. (author)

    There has been a growing interest among neonatologists and paediatricians regarding identification and evaluation of hypertension in the neonatal period. Despite the emergent normative data on blood pressure values in term and preterm neonates over the last two decades, there is still controversy regarding correct definition and classification of hypertension. This article will discuss the current definitions, available normative data and etiology of neonatal hypertension. There is paucity of records in terms of efficacy of antihypertensive drugs in this specific population and management is usually experience based, causing considerable heterogeneity amongst different units. This review article will also cover the evaluation, management, outcomes and follow up of neonatal hypertension with latest advances in this field.

    Fetal and neonatal hyperthyroidism may occur in mothers with Graves’ disease. Fetal thyrotoxicosis manifestation is observed with the transition of TSH receptor stimulating antibodies to the fetus from the 17th–20th weeks of pregnancy and with the fetal TSH receptors becoming responsive after 20 weeks. The diagnosis is confirmed by fetal tachycardia, goiter and bone age advancement in pregnancy and maternal treatment is conducted in accordance. The probability of neonatal hyperthyroidism is high in the babies of mothers that have ongoing antithyroid requirement and higher antibody levels in the last months of pregnancy. Clinical manifestation may be delayed by 7–17 days because of the antithyroid drugs taken by the mother. Neonatal hyperthyroidism symptoms can be confused with sepsis and congenital viral infections. Herein, the diagnosis and therapeutic approach are reviewed in cases of fetal neonatal hyperthyroidism. PMID:28439194

MÉTODOS: estudo de coorte transversal, realizado no período de 2004 a 2008, em maternidade localizada na zona sul da cidade de São Paulo, com 20.615 recém-nascidos de ambos os sexos, sem indicadores de risco para deficiência auditiva e submetidos à triagem auditiva neonatal. O teste foi realizado por intermédio das Emissões Otoacústicas Evocadas Transientes (EOAET. Os pacientes que falharam nas EOAET nas duas fases foram encaminhados para a realização do Potencial Evocado Auditivo do Tronco Encefálico (PEATE para a confirmação da deficiência auditiva neonatal. Empregou-se o Teste Exato de Fischer e o nível de significância adotado foi de 0,05 oupOBJECTIVES: to determine the incidence of hearing impairment in newborns, at a private maternity hospital in the city of São Paulo. METHODS: a cross-sectional cohort study was carried out covering the period between 2004 and 2008, at a maternity hospital located in the southern zone of the city of São Paulo, including 20,615 newborns of both sexes, with no risk factors for hearing impairment and who had undergone neonatal auditory screening. The test was carried out using the Evoked Transient Otoacoustic Emissions test. Patients who failed both phases of this test were referred to do a Brainstem Auditory Evoked Potential test to confirm the presence of neonatal auditory deficiency. Fischer 's exact test was used with a level of significance of 0.05 orp<0.05. RESULTS: the incidence of neonatal hearing impairment found in this study was 1.2/1000. CONCLUSION: state legislation allows neonatal auditory screening to be more effective in achieving early detection of neonatal hearing impairment. Neonatal auditory screening prevents future impairment of oral development and language acquisition in a social, professional and educational context.

La mortalidad perinatal y neonatal (en los primeros días de vida hasta los 27 días de vida y la mortalidad post-neonatal (entre 28 y 365 días de vida. El presente estudio se refiere a este último periodo de deceso, la tasa de mortalidad infantil post-neonatal (TMI post-neonatal, que si bien tiene un peso relativo menor, no deja de ser importante. Primeramente se analiza la influencia de otros factores, como los factores sociodemográficos a través del estudio de la relación entre el Índice de Desarrollo Social (IDS y la TMI post-neonatal. Luego se establece cuáles son los entes que proveen el servicio de agua potable en los diferentes distritos del país, y, dadas sus diferentes características, se analiza y verifica la hipótesis de que el ente proveedor (o administrador es un factor que explica la variación de la TMI post-neonatal entre distritos. Para reducir la TMI post-neonatal se debe obrar en la calidad del agua potable. La primera sugerencia es que en cada distrito debe haber un claro responsable y proveedor del agua potable. A juzgar por el éxito de ICAA y ESPH, parecen más exitosos los entes administradores basados en el control (en términos de definición de tarifas y control de calidad por parte de ARESEP, y no por Concejos Municipales que son más susceptibles a aplazar medidas como la colocación de medidores, la ejecución de ciertas inversiones, etc.

    In this article, the sensorineural hearing loss is presented as a possible sequelae of neonatal hyperbilirubinemia. In our program of early hipoacusia detection, 241 babies were examined from January 1996 until November 1999; 7 cases had a history of hyperbilirubinemia in the neonatal period and 2 of them were diagnosed of sensorineural hearing loss. We discuss how the bilirubin or any other associated factor might have been the cause and this could explain the selective affectation of some children.

    2014-01-01

    Staphylococcus aureus is the pathogen most frequently isolated from bovine mastitis worldwide, causing chronic intramammary infections that limit profitable dairying. The objective of this article is to characterize the mechanisms involved in S. aureus mammary gland infections considering two different aspects of the infectious process; on the one hand, the aspects involved in the host innate immune response and on the other hand, the capacity of this organism to evade the immune system and interact with different cell types. The exploration of S. aureus interactions with the immune response of bovine mammary gland will help identify targets to outline new preventive or curative alternatives for intramammary infections caused by this organism.

    1986-01-01

    A rapid, simple lysostaphin lysis susceptibility test to differentiate the genera Staphylococcus and Micrococcus was evaluated. Of 181 strains from culture collections, 95 of 95 Staphylococcus strains were lysed, and 79 of 79 Micrococcus strains were not lysed. The seven Planococcus strains were resistant. Clinical isolates (890) were tested with lysostaphin and for the ability to produce acid from glycerol in the presence of erythromycin. Overall agreement between the methods was 99.2%. All clinical Micrococcus strains (43) were resistant to lysostaphin, and all clinical Staphylococcus strains (847) were susceptible. Seven of the Staphylococcus strains did not produce acid from glycerol in the presence of erythromycin. This lysostaphin test provides results in 2 h. It is easier to perform than previously described lysostaphin lysis methods. It is also more rapid and accurate than the glycerol-erythromycin test. PMID:3519667

    We sought to examine neonatal morbidity associated with different maneuvers used among term patients who experience a shoulder dystocia. We conducted a retrospective cohort study of all women who experienced a clinically diagnosed shoulder dystocia at term requiring obstetric maneuvers at a single tertiary care hospital from 2005 through 2008. We excluded women with major fetal anomaly, intrauterine death, multiple gestation, and preterm. Women exposed to Rubin maneuver, Wood's screw maneuver, or delivery of the posterior arm were compared to women delivered by McRoberts/suprapubic pressure only, which served as the reference group. The primary outcome was a composite morbidity of neonatal injury (defined as clavicular or humeral fracture or brachial plexus injury) and neonatal depression (defined as Apgar dystocia, defined as time from delivery of fetal head to delivery of shoulders. Among the 231 women who met inclusion criteria, 135 were delivered by McRoberts/suprapubic pressure alone (57.9%), 83 women were exposed to Rubin maneuver, 53 women were exposed to Wood's screw, and 36 women were exposed to delivery of posterior arm. Individual maneuvers were not associated with composite morbidity, neonatal injury, or neonatal depression after adjusting for nulliparity and duration of shoulder dystocia. We found no association between shoulder dystocia maneuvers and neonatal morbidity after adjusting for duration, a surrogate for severity. Our results demonstrate that clinicians should utilize the maneuver most likely to result in successful delivery. Copyright © 2015 Elsevier Inc. All rights reserved.

    2016-08-01

    Full Text Available Background: Seizure is a common neurological disorder in neonatal age group!. Primary metabolic derangement is one of the important reason behind this convulsion during this period. Among primary metabolic derangement hypoglycemia, is most common followed by bypocalcaemia, hypomagnesaemia, low zinc status etc. As causes of many cases of convul­sion remain unknown in neonate. Objectives: To see the zinc status in the sera of neonate with convulsion. So that if needed early intervention can be taken up and thereby prevent complications. Method: A total of 50 neonates (1-28 days who had convulsion with no apparent reasons of convulsion were enrolled as cases and 50 healthy age and sex matched neonates were enrolled as controls. After a quick clinical evaluation serum zinc status was estimated from venous blood by atomic absorption method in Chemistry Division, Atomic Energy Centre. Low zinc was considered if serum value was <0.7mg/L. Results: Among a total of 50 cases 6% had low zinc value & 2% of controls also had low zinc level. The mean serwu zinc level of cases and controls were 1.57±0.95 and 2.37±1.06 mmol/1 respectively (p<0.01. Conclusion: From the study it is seen that low zinc value is an important cause of neonatal seizure due to primary metabolic abnormalities. So early recognition and treatment could save these babies from long term neurological sequelies.
