Background Appropriate antibiotic treatment of cat scratch disease (CSD) in pediatrics is not well established. Objective The purpose of this study was to evaluate the response rates of antibiotic therapy in pediatrics with CSD. Methods The electronic medical records of a cohort of pediatric patients with confirmed diagnosis of CSD (2006–2016) were reviewed, retrospectively. Data collection included patient demographics, clinical and laboratory results, antibiotic treatment and follow-up evaluations. Results One hundred and seventy-five patients (aged 7.4?±?4.4 years) had confirmed CSD. Azithromycin and trimethoprim/sulfamethoxazole (TMP/SMX) were the largest groups with documented effectiveness at follow-up visits. Resolution and improvement of CSD was observed in 51.4% and 61.5% of patients with azithromycin and TMP/SMX, respectively among those with follow-up assessment. The effectiveness of azithromycin and TMP/SMX was comparable (p?=?0.56). Conclusion Azithromycin and TMP/SMX were most frequently prescribed antibiotics. Azithromycin appeared to be an appropriate option for the treatment of CSD. TMP/SMX may be considered as an alternative antibiotic when azithromycin cannot be used.  相似文献

Purpose

Our goal was to characterize the contributions of A1c, fasting plasma glucose, and 2-hour plasma glucose to prediabetes prevalence and to characterize how those contributions differ among U.S. population subgroups.

Methods

In the 2011–2014 National Health and Nutrition Examination Survey, a nationally representative sample of the U.S. population, among participants without diabetes (N = 3387), we created area-proportional three-Venn diagrams showing the proportion above the prediabetes cutpoint for each of the three markers in the overall population and in subgroups defined by age, race/ethnicity, sex, and body mass index.

Results

In the overall population, 28.3% had fasting plasma glucose above the prediabetes cutpoint, 21.7% had A1c above the prediabetes cutpoint, and 13.3% had 2-hour plasma glucose above the prediabetes cutpoint. Adolescents and young adults tended to have only one marker exceed the prediabetes cutpoint, while older age groups tended to have multiple markers above the prediabetes cutpoint. For non-Hispanic whites, non-Hispanic blacks, non-Hispanic Asians, and Mexican-Americans, the unadjusted total percent above the A1c cutpoint was 19.3%, 36.4%, 20.5%, and 21.4%, respectively.

Conclusions

We provide a graphic reference showing fasting plasma glucose was the largest contributor to prediabetes prevalence in the overall population, followed by A1c and then 2-hour plasma glucose.  相似文献

Purpose

Potential roles of inherited and environmental risk factors in pathogenesis of Langerhans cell histiocytosis (LCH), a myeloid neoplastic disorder, are undefined. We therefore evaluated the role of parental and perinatal factors on the risk of this childhood cancer.

Methods

Information on LCH cases (n = 162) for the period 1995–2011 was obtained from the Texas Cancer Registry. Birth certificate controls were frequency-matched on year of birth at a ratio of 10:1 for the same period. Variables evaluated included parental age, race/ethnicity, size for gestational age, and birth order. Logistic regression was used to generate an adjusted odds ratio (aOR) and 95% confidence interval (CI) testing the association between each factor and LCH.

Results

Few perinatal or parental factors were associated with LCH risk, with the exception of race/ethnicity. Mothers of Hispanic ethnicity were more likely to have children who developed LCH compared to non-Hispanic whites (aOR: 1.51; 95% CI: 1.02–2.25). This risk increased when both parents were Hispanic (aOR: 1.80; 95% CI: 1.13–2.87). Non-Hispanic black mothers were suggested as less likely to give birth to offspring who developed LCH compared to non-Hispanic whites (aOR: 0.50; 95% CI: 0.24–1.02).

Conclusions

LCH is characterized by somatic mutations in MAPK pathway genes in myeloid precursors. Increased risk for LCH in children of Hispanic parents suggests potential impact of inherited factors on LCH pathogenesis.  相似文献
