RESUMEN

BACKGROUND: Otitis is commonly associated with community-acquired bacterial meningitis, but the role of ear surgery as treatment is debated. In this study, we investigated the impact of otitis and ear surgery on outcome of adults with community-acquired bacterial meningitis. METHODS: We analyzed episodes of adults with community-acquired bacterial meningitis from a nationwide prospective cohort study in the Netherlands, between March 2006 and July 2021. RESULTS: A total of 2548 episodes of community-acquired bacterial meningitis were evaluated. Otitis was present in 696 episodes (27%). In these patients the primary causative pathogen was Streptococcus pneumoniae (615 of 696 [88%]), followed by Streptococcus pyogenes (5%) and Haemophilus influenzae (4%). In 519 of 632 otitis episodes (82%) an ear-nose-throat specialist was consulted, and surgery was performed in 287 of 519 (55%). The types of surgery performed were myringotomy with ventilation tube insertion in 110 of 287 episodes (38%), mastoidectomy in 103 of 287 (36%), and myringotomy alone in 74 of 287 (26%). Unfavorable outcome occurred in 210 of 696 episodes (30%) and in 65 of 696 episodes was fatal (9%). Otitis was associated with a favorable outcome in a multivariable analysis (odds ratio 0.74; 95% confidence interval [CI] .59-.92; P = .008). There was no association between outcome and ear surgery. CONCLUSIONS: Otitis is a common focus of infection in community-acquired bacterial meningitis in adults, with S. pneumoniae being the most common causative pathogen. Presence of otitis is associated with a favorable outcome. Ear surgery's impact on the outcome of otogenic meningitis patients remains uncertain.

RESUMEN

Despite previous reports on the emergence of Malassezia pachydermatis strains with decreased susceptibility to azoles, there is limited information on the actual prevalence and genetic diversity of azole-resistant isolates of this yeast species. We assessed the prevalence of azole resistance in M. pachydermatis isolates from cases of dog otitis or skin disease attended in a veterinary teaching hospital during a 2-year period and analyzed the ERG11 (encoding a lanosterol 14-α demethylase, the primary target of azoles) and whole genome sequence diversity of a group of isolates that displayed reduced azole susceptibility. Susceptibility testing of 89 M. pachydermatis isolates from 54 clinical episodes (1-6 isolates/episode) revealed low minimum inhibitory concentrations (MICs) to most azoles and other antifungals, but 11 isolates from six different episodes (i.e., 12.4% of isolates and 11.1% of episodes) had decreased susceptibility to multiple azoles (fluconazole, itraconazole, ketoconazole, posaconazole, ravuconazole, and/or voriconazole). ERG11 sequencing of these 11 azole-resistant isolates identified eight DNA sequence profiles, most of which contained amino acid substitutions also found in some azole-susceptible isolates. Analysis of whole genome sequencing (WGS) results revealed that the azole-resistant isolates from the same episode of otitis, or even different episodes affecting the same animal, were more genetically related to each other than to isolates from other dogs. In conclusion, our results confirmed the remarkable ERG11 sequence variability in M. pachydermatis isolates of animal origin observed in previous studies and demonstrated the value of WGS for disentangling the epidemiology of this yeast species.


We analyzed the prevalence and diversity of azole-resistant Malassezia pachydermatis isolates in a veterinary hospital. A low prevalence of multi-azole resistance (c.10% of isolates and cases) was found. Whole genome and ERG11 sequencing of resistant isolates revealed remarkable genetic diversity.

RESUMEN

BACKGROUND: COVID-19 pandemic is thought to have changed the epidemiology of some pediatric neurosurgical disease: among them are the intracranial complications of sinusitis and otitis (ICSO). According to some studies on a limited number of cases, both streptococci-related sinusitis and ICSO would have increased immediately after the pandemic, although the reason is not clear yet (seasonal changes versus pandemic-related effects). The goal of the present survey of the European Society for Pediatric Neurosurgery (ESPN) was to collect a large number of cases from different European countries encompassing the pre-COVID (2017-2019), COVID (2020-2021), and post-COVID period (2022-June 2023) looking for possible epidemiological and/or clinical changes. MATERIAL AND METHODS: An English language questionnaire was sent to ESPN members about year of the event, patient's age and gender, presence of immune-deficit or other favoring risk factors, COVID infection, signs and symptoms at onset, site of primary infection, type of intracranial complication, identified germ, type and number of surgical operations, type and duration of medical treatment, clinical and radiological outcome, duration of the follow-up. RESULTS: Two hundred fifty-four cases were collected by 30 centers coming from 14 different European countries. There was a statistically significant difference between the post-COVID period (129 children, 86 cases/year, 50.7% of the whole series) and the COVID (40 children, 20 cases/year, 15.7%) or the pre-COVID period (85 children, 28.3 cases/year, 33.5%). Other significant differences concerned the presence of predisposing factors/concurrent diseases (higher in the pre-COVID period) and previous COVID infection (higher in the post-COVID period). No relevant differences occurred as far as demographic, microbiological, clinical, radiological, outcome, morbidity, and mortality data were concerned. Paranasal sinuses and middle ear/mastoid were the most involved primary site of infection (71% and 27%, respectively), while extradural or subdural empyema and brain abscess were the most common ICSO (73% and 17%, respectively). Surgery was required in 95% of cases (neurosurgical and ENT procedure in 71% and 62% of cases, respectively) while antibiotics in 99% of cases. After a 12.4-month follow-up, a full clinical and radiological recovery was obtained in 85% and 84% of cases, respectively. The mortality rate was 2.7%. CONCLUSIONS: These results suggest that the occurrence of ICSO was significantly increased after the pandemic. Such an increase seems to be related to the indirect effects of the pandemic (e.g., immunity debt) rather than to a direct effect of COVID infection or to seasonal fluctuations. ICSO remain challenging diseases but the pandemic did not affect the management strategies nor their prognosis. The epidemiological change of sinusitis/otitis and ICSO should alert about the appropriate follow-up of children with sinusitis/otitis.

RESUMEN

OBJECTIVE: The natural course of childhood asthma, after its onset, is characterized by periods of persistence, relapse and remission. To investigate personal and early life factors associated with new-onset asthma, persistence and remission among children. METHODS: The study was conducted in the province of Saskatchewan, Canada. Children in grades Kindergarten to Grade 8 (ages 5-14 years) participated in a cross-sectional study in 2013. In 2015, we approached those who gave consent in 2013 to be re-contacted, creating a prospective cohort. Data were collected using questionnaires in both years. Participants in 2013 who also had data in 2015 (25%: n = 324/1,348) had their asthma status reclassified and longitudinal descriptors were applied: "no asthma", "new-onset asthma", "persistent" or "remission". Personal and early life factors associations with asthma outcomes in 2015 were evaluated. RESULTS: Among those without asthma in 2013 (n = 245), the incidence of new-onset asthma in 2015 was 7.2%. Among those with asthma in 2013 (n = 79), 47.1% had remission and 52.9% had persistent asthma in 2015. Parental history of asthma (adjusted odds ratio (aOR): 4.99; 95% confidence interval (CI): 1.88-28.27), early life respiratory infection (aOR: 1.92; 95%CI: 1.47-7.88), early life allergy [aOR: 6.39; 95%CI: 1.34-30.58) and early life infection (aOR: 4.99; 95%CI: 1.19-20.93) were associated with new onset asthma. Similarly, while parental history of asthma (aOR: 1.13; 95%CI: 0.29-4.34), early life respiratory infection (aOR: 2.71; 95%CI: 0.70-10.45), and early life ear infection (aOR: 1.34; 95%CI: 0.36-5.05) were also positively association with persistent asthma, the associations were not statistically significant. CONCLUSION: Parental history of asthma, early life respiratory infection and allergy might not only influence the onset of childhood asthma but also be associated with asthma persistence.

RESUMEN

The emerging yeast Candida auris can be highly drug resistant, causing invasive infections, and large outbreaks. C. auris went from an unknown pathogen a decade ago to being reported in over thirty countries on six continents. C. auris consists of four discrete clades, based on where the first isolates of the clade were reported, South Asian (clade I), East Asian (clade II), African (clade III), and South American (clade IV). These clades have unique genetic and biochemical characteristics that are important to understand and inform the global response to C. auris Clade II has been underrepresented in the literature despite being the first one discovered. In this issue of the Journal of Clinical Microbiology, Y. J. Kwon et al. (J Clin Microbiol 57:e01624-18, 2019, https://doi.org/10.1128/JCM.01624-18) describe the largest collection of clinical isolates from Clade II, which is also the longest-running span of clinical cases, 20 years, from any single region to date. Clade II appears to have a propensity for the ear that is uncharacteristic of the other clades, which typically cause invasive infections and large-scale outbreaks. This study provides new information on an understudied lineage of C. auris and has important implications for future surveillance.

RESUMEN

OBJECTIVE: The aim of the study was to investigate prospective, longitudinal associations between maternal prenatal cortisol response to an interpersonal stressor and child health for the subsequent 3 years. METHODS: One hundred twenty-three women expecting their first child provided salivary cortisol samples between 12 and 32 weeks of gestation (M (SD) = 22.4 (4.9) weeks) before and after a videotaped couple conflict discussion with their partner. Mothers reported on overall child health and several indicators of child illness (sick doctor visits, fevers, ear, and respiratory infections) when children were 6 months (n = 114), 1 (n = 116), and 3 (n = 105) years old. Associations between maternal prenatal cortisol reactivity and recovery and later child health at each of the three time points were analyzed using longitudinal regression models. RESULTS: Greater cortisol reactivity in response to the couple conflict discussion was associated with maternal self-report of better overall child health (p = .016, 95% CI = 0.06-1.30, Cohen's f = 0.045) across the study period. Greater cortisol reactivity was also associated with lower incidence rate ratios for maternal reports of sick doctor visits (incidence rate ratio 95% CI = 0.25-0.83, p = .006), fevers (95% CI = 0.25-0.73, p = .002), ear infections (95% CI = 0.25-0.58, p < .001), and respiratory infections (95% CI = 0.08-1.11, p = .073). Cortisol recovery was unrelated to study outcomes (all p's > 0.05). Maternal prenatal depressive symptoms moderated the association between cortisol reactivity and overall child health (p = .034, 95% CI = 0.07-1.87 for interaction term) but no other health outcomes (p's > 0.05). Among women with lower depressive symptoms, cortisol reactivity was not associated with overall child health; among women with higher levels of depressive symptoms, greater cortisol reactivity was associated with better overall child health. CONCLUSIONS: This study provides longitudinal evidence that greater maternal cortisol reactivity to a salient interpersonal stressor during pregnancy is associated with fewer child health problems and better maternal report of overall child health during infancy and into early childhood.

RESUMEN

BACKGROUND: Indigenous youth have higher rates of chronic health conditions interfering with healthy development, including high rates of ear, dental, chest and musculoskeletal pain, as well as headache, arthritis and mental health issues. This study explores differences in pain-related diagnoses in First Nations and non-First Nations children. METHODS: Data from a study population of age- and sex-matched First Nations and non-First Nations children and youth were accessed from a specific region of Atlantic Canada. The primary objective of the study was to compare diagnosis rates of painful conditions and specialist visits between cohorts. The secondary objective was to determine whether there were correlations between early physical pain exposure and pain in adolescence (physical and mental health). RESULTS: Although ear- and throat-related diagnoses were more likely in the First Nations group than in the non-First Nations group (ear 67.3% v. 56.8%, p < 0.001; throat 89.3% v. 78.8%, p < 0.001, respectively), children in the First Nations group were less likely to see a relevant specialist (ear 11.8% v. 15.5%, p < 0.001; throat 12.7% v. 16.1%, p < 0.001, respectively). First Nations newborns were more likely to experience an admission to the neonatal intensive care unit (NICU) than non-First Nations newborns (24.4% v. 18.4%, p < 0.001, respectively). Non-First Nations newborns experiencing an NICU admission were more likely to receive a mental health diagnosis in adolescence, but the same was not found with the First Nations group (3.4% v. 5.7%, p < 0.03, respectively). First Nations children with a diagnosis of an ear or urinary tract infection in early childhood were almost twice as likely to have a diagnosis of headache or abdominal pain as adolescents (odds ratio [OR] 1.9, 95% confidence interval [CI] 1.1-3.0, and OR 1.7, 95% CI 1.2-2.3, respectively). INTERPRETATION: First Nations children were diagnosed with more pain than non-First Nations children, but did not access specific specialists or mental health services, and were not diagnosed with mental health conditions, at the same rate as their non-First Nations counterparts. Discrepancies in pain-related diagnoses and treatment are evident in these specific comparative cohorts. Community-based health care access and treatment inquiries are required to determine ways to improve care delivery for common childhood conditions that affect health and development.

RESUMEN

Circulating 25-hydroxy vitamin D (25(OH)D) is related to decreased rates of gastrointestinal and ear infections in school-age children. Vitamin D-binding protein (DBP) transports 25(OH)D and exerts immunological functions; however, it is unknown whether DBP is associated with infectious morbidity in children. We quantified plasma DBP concentrations in 540 school-age children at the time of recruitment into a cohort study in Bogotá, Colombia and obtained daily information on infectious morbidity symptoms and doctor visits during the school year. We compared the incidence rates of gastrointestinal and respiratory symptoms across quartiles of DBP concentration by estimating adjusted incidence rate ratios (IRRs) with 95% confidence interval (CI). We also estimated the per cent of the associations between DBP and morbidity that were mediated through 25(OH)D using a counterfactual frame. Mean ± s.d. DBP concentration was 2650 ± 1145 nmol/l. DBP was inversely associated with the rates of diarrhoea with vomiting (IRR for quartiles 2-4 vs. 1 = 0.48; 95% CI 0.25-0.92; P = 0.03) and earache/ear discharge with fever (IRR for quartiles 2-4 vs. 1 = 0.29; 95% CI 0.12-0.71; P = 0.006). The DBP-morbidity associations were not mediated through 25(OH)D. We conclude that plasma DBP predicts lower incidence of gastrointestinal and ear infections in school-age children independent of 25(OH)D.

RESUMEN

OBJECTIVES: The effects of prenatal exposure to Polychlorinated biphenyls (PCBs) on the development of asthma, frequent ear infections, and eczema/hay fever are not well understood. We aim to investigate associations between prenatal PCB exposure and these health outcomes in the offspring of women who worked at the LaSalle Electrical Utilities Company (EUC). METHODS: A retrospective cohort with at least one live birth and known employment time at EUC was eligible for this analysis. Exposure was defined and categorized by the number of fiscal quarters worked during the PCB era (1952-1981). A total of 288 women with 800 live births were included. A Chi-Square test was used to compare maternal and child characteristics across exposure groups and repeated measures logistic regression, controlling for clustering among siblings, was used to assess the associations between prenatal PCB exposure and these outcomes. RESULTS: After adjustment for confounding and independent maternal predictors, 1-4 quarters of prenatal exposure to PCBs increased the odds for asthma (OR 3.24[1.30-8.09]), eczema/hay fever (OR 3.29[1.54-7.04]), and frequent ear infections (OR 2.24[1.19-4.22]) when compared with persons unexposed/exposed only to naphthalenes. The significance of the associations varied by exposure period and level of exposure, with the strongest associations in those employed exclusively after 1952 when PCBs were introduced. CONCLUSIONS: These results support previous findings of associations of prenatal exposure to PCBs with asthma, eczema/hay fever, and frequent ear infections. Additional prospective studies are needed to confirm these findings. Also required are more precise PCB exposures to separate them from other exposures in occupational settings.

RESUMEN

Empiric initial antibiotic therapy of bacterial infections is based primarily upon the susceptibility of the most common causative pathogens. The purpose of this study was to provide susceptibility data on six bacterial species known to cause ear, nose and throat (ENT) infections. A total of 1066 isolates collected during a nationwide laboratory-based surveillance study were analysed. All Streptococcus pyogenes isolates were penicillin (PEN)-susceptible, indicating that natural penicillins can still be recommended as the first-line treatment for group A streptococcal tonsillopharyngitis. Of the S. pneumoniae isolates, 92.9% were PEN-susceptible and of the Haemophilus influenzae isolates, 89.7% were amoxicillin-susceptible, retaining aminopenicillins as the first-line treatment for acute otitis media (AOM) and acute rhinosinusitis (ARS), in case antibiotic therapy is considered. In contrast, cefuroxime axetil seems less likely to be suitable for the treatment of AOM or ARS, as all Moraxella catarrhalis and >99% of the H. influenzae isolates were categorised as intermediate or resistant. The susceptibility rates of Pseudomonas aeruginosa were 97-100% for the drugs tested, except for the fluoroquinolones (87.6%). Overall, bacterial isolates from outpatients presenting with ENT infections showed low frequencies of resistance in Germany. However, given the emergence of multidrug resistance to standard antibiotics in Escherichia coli and other pathogens, inappropriate use of broad-spectrum antibiotics for the treatment of ENT infections has to be avoided.

RESUMEN

BACKGROUND: Pseudomonas aeruginosa is an opportunistic pathogen of the canine ear canal and occupies aquatic habitats in the environment. Nosocomial and zoonotic transmission of P. aeruginosa have been documented, including clonal outbreaks. HYPOTHESIS/OBJECTIVES: The primary objective of this study was to assess various environmental exposures as potential risk factors for canine Pseudomonas otitis. It was hypothesized that isolates derived from infected ears would be clonal to isolates derived from household water sources and the mouths of human and animal companions of the study subjects. ANIMALS: Seventy seven privately owned dogs with otitis were enrolled, along with their human and animal household companions, in a case-control design. METHODS: Data on potential risk factors for Pseudomonas otitis were collected. Oral cavities of all study subjects, their human and animal companions, and household water sources were sampled. Pulsed field gel electrophoresis was used to estimate clonal relatedness of P. aeruginosa isolates. RESULTS: In a multivariate model, visiting a dog park was associated with 77% increased odds of case status (P = 0.048). Strains clonal to the infection isolates were obtained from subjects' mouths (n = 18), companion pets' mouths (n = 5), pet owners' mouths (n = 2), water bowls (n = 7) and water taps (n = 2). Clonally related P. aeruginosa isolates were obtained from dogs that had no clear epidemiological link. CONCLUSIONS AND CLINICAL IMPORTANCE: Genetic homology between otic and environmental isolates is consistent with a waterborne source for some dogs, and cross-contamination with other human and animal members within some households.

RESUMEN

A total of 216 colonies of Malassezia pachydermatis from 28 cases of fungal otitis or dermatitis in pets were genotyped by M13 fingerprinting and tested for antifungal susceptibility. A huge genetic diversity was found (157 M13 types in total), with all animals having a polyclonal pattern of infection (5.4 ± 1.5 genotypes/sample). Furthermore, analysis of molecular variance (AMOVA) revealed that most genetic diversity (44%) was found at the within sample level. In contrast, variability in antifungal susceptibility among isolates from the same sample was less important, with different M13 types displaying in most cases identical or very similar MIC results. Most isolates displayed high in vitro susceptibility to amphotericin B, terbinafine and all azoles tested except fluconazole, for which MIC values were always ≥4 µg/ml and a 26.9% of isolates displayed values ≥32 µg/ml. We conclude that although characterization of multiple yeast isolates results in a considerable increase in laboratory workload and expenses, it may help to get a better understanding of the epidemiology of M. pachydermatis in a given patient population.

RESUMEN

Despite the benefits of smoke-free legislation on adult health, little is known about its impact on children's health. We examined the effects of tobacco control policies on the rate of emergency department (ED) visits for childhood asthma (N=128,807), ear infections (N=288,697), and respiratory infections (N=410,686) using outpatient ED visit data in Massachusetts (2001-2010), New Hampshire (2001-2009), and Vermont (2002-2010). We used negative binomial regression models to analyze the effect of state and local smoke-free legislation on ED visits for each health condition, controlling for cigarette taxes and health care reform legislation. We found no changes in the overall rate of ED visits for asthma, ear infections, and upper respiratory infections after the implementation of state or local smoke-free legislation or cigarette tax increases. However, an interaction with children's age revealed that among 10-17-year-olds state smoke-free legislation was associated with a 12% reduction in ED visits for asthma (adjusted incidence rate ratios (aIRR) 0.88; 95% CI 0.83, 0.95), an 8% reduction for ear infections (0.92; 0.88, 0.97), and a 9% reduction for upper respiratory infections (0.91; 0.87, 0.95). We found an overall 8% reduction in ED visits for lower respiratory infections after the implementation of state smoke-free legislation (0.92; 0.87, 0.96). The implementation of health care reform in Massachusetts was also associated with a 6-9% reduction in all children's ED visits for ear and upper respiratory infections. Our results suggest that state smoke-free legislation and health care reform may be effective interventions to improve children's health by reducing ED visits for asthma, ear infections, and respiratory infections.

RESUMEN

BACKGROUND: Breast-feeding is protective against respiratory infections in early life. Given the co-evolutionary adaptations of humans and cattle, bovine milk might exert similar anti-infective effects in human infants. OBJECTIVE: To study effects of consumption of raw and processed cow's milk on common infections in infants. METHODS: The PASTURE birth cohort followed 983 infants from rural areas in Austria, Finland, France, Germany, and Switzerland, for the first year of life, covering 37,306 person-weeks. Consumption of different types of cow's milk and occurrence of rhinitis, respiratory tract infections, otitis, and fever were assessed by weekly health diaries. C-reactive protein levels were assessed using blood samples taken at 12 months. RESULTS: When contrasted with ultra-heat treated milk, raw milk consumption was inversely associated with occurrence of rhinitis (adjusted odds ratio from longitudinal models [95% CI]: 0.71 [0.54-0.94]), respiratory tract infections (0.77 [0.59-0.99]), otitis (0.14 [0.05-0.42]), and fever (0.69 [0.47-1.01]). Boiled farm milk showed similar but weaker associations. Industrially processed pasteurized milk was inversely associated with fever. Raw farm milk consumption was inversely associated with C-reactive protein levels at 12 months (geometric means ratio [95% CI]: 0.66 [0.45-0.98]). CONCLUSIONS: Early life consumption of raw cow's milk reduced the risk of manifest respiratory infections and fever by about 30%. If the health hazards of raw milk could be overcome, the public health impact of minimally processed but pathogen-free milk might be enormous, given the high prevalence of respiratory infections in the first year of life and the associated direct and indirect costs.

RESUMEN

AIM: To study the effectiveness of anti-pneumococcal vaccination of children in the organiza- tion of anti-epidemic measures in the areas of the flood in the Amur region. MATERIAL AND METHODS: The monitoring program included 4988 children aged 2 to 5 years who have risk factors for pneu- mococcal infection. Pneumococcal conjugate vaccine Prevenar- 13 was used for immunization. Data on the incidence of child with acute respiratory infection, acute otitis media, pneumonia, meningitis during the post-vaccination period were taken into account. To evaluate the effective- ness of vaccination we used indicators and specific criteria (coefficient prophylactic vaccination and infection index). RESULTS: The level of total morbidity of children in post-immunization pe- riod decreased by 13.6%; the number of cases ofpneumonia in the population of observed children decreased by 2.3 times; the total duration of the illness in children decreased by 14.6%, the number of.courses of antibiotic therapy was reduced by 21.3%, the number of hospital admissions of children - 38.4%, the number of days of temporary disability ofparents - 11.1%. Direct dependence of the degree of effectiveness of vaccination against pneumococcal disease by the age of children is determined. CONCLUSION: The findings suggest that implementation of the program of clinical and epidemiological monitoring and prevention of community-acquired pneumonia with use of a vaccine against pneumococcal infections in the territory of the Amur Region has a high level of medical and socio-economic efficiency.

RESUMEN

AIM: We analyzed data from 71 patients with chronic granulomatous disease (CGD) with a confirmed genetic diagnosis, registered in the online Latin American Society of Primary Immunodeficiencies (LASID) database. RESULTS: Latin American CGD patients presented with recurrent and severe infections caused by several organisms. The mean age at disease onset was 23.9 months, and the mean age at CGD diagnosis was 52.7 months. Recurrent pneumonia was the most frequent clinical condition (76.8%), followed by lymphadenopathy (59.4%), granulomata (49.3%), skin infections (42%), chronic diarrhea (41.9%), otitis (29%), sepsis (23.2%), abscesses (21.7%), recurrent urinary tract infection (20.3%), and osteomyelitis (15.9%). Adverse reactions to bacillus Calmette-Guérin (BCG) vaccination were identified in 30% of the studied Latin American CGD cases. The genetic diagnoses of the 71 patients revealed 53 patients from 47 families with heterogeneous mutations in the CYBB gene (five novel mutations: p.W361G, p.C282X, p.W483R, p.R226X, and p.Q93X), 16 patients with the common deletion c.75_76 del.GT in exon 2 of NCF1 gene, and two patients with mutations in the CYBA gene. CONCLUSION: The majority of Latin American CGD patients carry a hemizygous mutation in the CYBB gene. They also presented a wide range of clinical manifestations most frequently bacterial and fungal infections of the respiratory tract, skin, and lymph nodes. Thirty percent of the Latin American CGD patients presented adverse reactions to BCG, indicating that this vaccine should be avoided in these patients.

RESUMEN

OBJECTIVES: It is known that childhood hearing function can become impaired after the occurrence of specific infections. However, evidence on the effect of common childhood infections on adult hearing function is limited. The objective of the study was to identify whether associations exist between the occurrence of common childhood infections in a UK birth cohort and hearing function across different frequencies at age 61 to 63 years. DESIGN: The Newcastle Thousand Families study is a birth cohort of all individuals born in May and June 1947 to mothers resident in Newcastle upon Tyne, United Kingdom. Of the original cohort members who had an audiometry test at age 61 to 63 years, 333 had data available on infections during their first year of life and 296 on infections up to their fifth year of life. These data were analyzed using linear regression in relation to adult hearing function across differing frequencies in isolation. RESULTS: After adjustment for sex, overcrowding in the first year, having had an ear operation, and having worked in a loud environment, significant negative associations were identified between adult hearing and tonsillitis at 250 Hz (p = 0.013), 1 kHz (p = 0.018), 6 kHz (p = 0.012), and 8 kHz (p = 0.033); otorrhea at 4 kHz (p = 0.005), 6 kHz (p = 0.003), and 8 kHz (p = 0.002); bronchitis (two or more episodes) at 2 kHz (p = 0.001), 3 kHz (p = 0.005), 4 kHz (p = 0.009), 6 kHz (p < 0.001), and 8 kHz (p < 0.001); and the total number of severe respiratory infections in the first year at 2 kHz (p = 0.037), 3 kHz (p = 0.049), 4 kHz (p = 0.030), 6 kHz (p < 0.001), and 8 kHz (p = 0.006). That is, individuals who had tonsillitis, bronchitis (twice or more), otorrhea, or a severe respiratory infection (twice or more) in their first year of life were more likely to have impaired adult hearing function than those who did not have any infections in early life. CONCLUSION: The occurrence of some, but not all, childhood infections appears to have an effect on adult hearing function across different frequencies. Reducing the incidence of infectious diseases in early life may reduce subsequent incidence of hearing impairment among adults. However, further research in modern cohorts is needed to clarify the links between infectious childhood diseases and adult hearing function.

RESUMEN

BACKGROUND: In 1992, the American Academy of Pediatrics discouraged prone sleeping positions because of its association with sudden infant death syndrome. After this was an increased incidence of deformational plagiocephaly (DP). METHODS: A retrospective review was completed for patients with DP and craniosynostosis seen by plastic surgeons at a tertiary medical center during a 19-year period. Two groups of patients were evaluated before (1988-1995) and after (1996-2007) implementation of the "Back to Sleep" campaign. RESULTS: Of the 5169 patients, those with craniosynostosis (n = 279) had a mean age at initial evaluation before and after 1996 of 12.4 versus 5.6 months (P = 0.0008). There was a trend of decreasing age at initial evaluation and first surgery after 1996. For patients with DP (n = 4890), the mean age at initial evaluation before and after 1996 was 11.5 versus 6.0 months (P = 0.10). There was a trend of decreasing age at initial evaluation and DP correction after 1996. The majority of patients had right-sided DP (50.2%), followed by left-sided (24.7%) and bilateral (18.9%). There was no significant difference in DP correction rate (67% versus 87%) or the mean age that DP was corrected (12.8 versus 11.8 mo) before and after 1996. Compared with 1996 to 1999, there was a 214% and 390% increase in DP referrals from 2000 to 2003 and 2004 to 2007. For craniosynostosis, there was a 27% and 129% increase in referrals. CONCLUSIONS: The increasing incidence of DP since the Back to Sleep campaign is concerning, but a positive outcome is that patients are being referred and treated at a younger age.

RESUMEN

The surveillance of the serotype pattern and antibiotic resistance of S. pneumoniae in various geographical regions is required for the validity of rational etiotrophic therapy of pneumococcal infections and the choice of the optimal vaccines for their prophylaxis. 250 S. pneumoniae isolates from children with acute otitis or pneumonia and healthy carriers in St. Petersburg in 2010-2013 were investigated. The analysis of the serotype pattern of the pneumococci showed that 13-valent conjugate vaccine was the most active (86.1% of pneumococci causing pneumonia and 86.4% of pneumococci causing acute otitis). The isolates were higly resistant to beta-lactams and macrolides. By the EUCAST criteria, the decrease in the susceptibility to penicillin, cefotaxime, erythromycin and ceftarolin was observed in 32.4%, 14%, 33.2 and 6% of the isolates respectively. 22.4% of the isolates showed associate resistance to penicillin and erythromycin.. No resistance to moxifloxacin was detected. The frequency of resistance to tetracycline, co-trimoxasole and chloramphenicol in various patients ranged within 30-50%. The prevalence of the antibiotic resistance was mainly characteristic of the isolates serotypes 19A, 19F, 14 and serogroup 6.
