RESUMO
BACKGROUND AND OBJECTIVES: Air pollutants play a pivotal role in the frequency and severity of asthma symptoms. As cleaner air initiatives are increasingly being implemented, it is important to appraise how these changes relate to acute pediatric asthma. The objective of this study is to evaluate the effect of a Gas and Electric Company's transition from using coal to natural gas as their fuel source on pediatric asthma-related illnesses in Louisville, KY. METHODS: Data were collected for children 2-17 years old from a large regional healthcare system, for which an asthma-related primary diagnosis was present between April 1, 2013 and April 1, 2018. Using an interrupted time series design, we analyzed monthly rates of asthma-related visits to urgent care (UC) and emergency departments (ED). Segmented Poisson regression models were used to assess whether the power company's transition was associated with changes in trends of asthma-related visits. RESULTS: There were a total of 7,735 subjects who met inclusion criteria. Prior to the complete factory transition from coal to natural gas, the mean monthly rate for asthma-related visits was 163.9. After the transition, we observed a significant decrease to a mean monthly rate of 100.3 asthma-related visits (p < 0.001). In addition, the proportion of inpatient (23.7% vs. 30.5%, p < 0.001) visits significantly increased, while ED & UC (76.3 vs. 69.5%, p < 0.001) were significantly decreased. CONCLUSION: Converting an electrical power plant from coal to natural gas lead to a profound and sustained decrease in pediatric acute asthma exacerbation in Louisville, KY.

BACKGROUND: The value of continuous glucose monitoring in the management of type 1 diabetes mellitus has not been determined. METHODS: In a multicenter clinical trial, we randomly assigned 322 adults and children who were already receiving intensive therapy for type 1 diabetes to a group with continuous glucose monitoring or to a control group performing home monitoring with a blood glucose meter. All the patients were stratified into three groups according to age and had a glycated hemoglobin level of 7.0 to 10.0%. The primary outcome was the change in the glycated hemoglobin level at 26 weeks. RESULTS: The changes in glycated hemoglobin levels in the two study groups varied markedly according to age group (P=0.003), with a significant difference among patients 25 years of age or older that favored the continuous-monitoring group (mean difference in change, -0.53%; 95% confidence interval [CI], -0.71 to -0.35; P<0.001). The between-group difference was not significant among those who were 15 to 24 years of age (mean difference, 0.08; 95% CI, -0.17 to 0.33; P=0.52) or among those who were 8 to 14 years of age (mean difference, -0.13; 95% CI, -0.38 to 0.11; P=0.29). Secondary glycated hemoglobin outcomes were better in the continuous-monitoring group than in the control group among the oldest and youngest patients but not among those who were 15 to 24 years of age. The use of continuous glucose monitoring averaged 6.0 or more days per week for 83% of patients 25 years of age or older, 30% of those 15 to 24 years of age, and 50% of those 8 to 14 years of age. The rate of severe hypoglycemia was low and did not differ between the two study groups; however, the trial was not powered to detect such a difference. CONCLUSIONS: Continuous glucose monitoring can be associated with improved glycemic control in adults with type 1 diabetes. Further work is needed to identify barriers to effectiveness of continuous monitoring in children and adolescents. (ClinicalTrials.gov number, NCT00406133.)

BACKGROUND: Few series describe endoscopic drainage of pancreatic abscesses. Abscesses are complications of pancreatitis, presenting with sepsis, peritonitis, or both. This report describes the feasibility and efficacy of natural orifice translumenal endoscopic surgery for pancreatic abscesses. METHODS: This study reviewed 35 consecutively treated patients for the period 1994-2007. The approaches alone or in combination were transmural (transgastric or transduodenal) and transpapillary. The criteria for abscesses were two or more of the following: fever, abdominal pain, elevated white blood count (WBC), and positive fluid cultures. RESULTS: The 35 patients (19 men and 16 women) had a mean age of 49 years. The abscesses had idiopathic (37%), gallstone (32%), alcohol (20%), and divisum (11%) etiologies. The presenting signs were abdominal pain (80%), positive cultures (69%), fever (57%), elevated WBC (51%), and nausea/vomiting (39%). The approaches for abscess drainage were as follows: transgastric (n = 15, 43%), transduodenal (n = 4, 11%), transgastric combined with transpapillary (n = 8, 23%), transduodenal combined with transpapillary (n = 1, 3%), and transpapillary alone (n = 7, 20%). A total of 28 patients (80%) achieved successful endoscopic pancreatic abscess drainage, whereas 7 (20%) required surgery. Of these seven patients, two (6%) required emergent laparotomy to control bleeding, and the remaining five (14%) were explored after failure to demonstrate clinical improvement from endoscopic drainage. Three patients required internal drainage, and two patients required distal pancreatectomy. The mean follow-up period was 15 months, and the complication rate was 6%. No one died from the procedure. CONCLUSION: Endoscopic surgery for pancreatic abscess is feasible and effective. It is an alternative to surgery that currently can be considered a primary treatment option for selected pancreatic abscesses.

To compare the cost of several common modalities used to treat non-genital warts in immunocompetent patients, we identified studies published in English using standard search strategies and evaluated the literature for the following common non-genital wart therapies: cryotherapy with liquid nitrogen, carbon dioxide and pulsed-dye laser therapy, topical squaric acid, intralesional bleomycin, intralesional interferon alpha injections, and intralesional immunotherapy with Candida antigens. Standard treatment algorithms, compiled by dermatologists experienced in the treatment of patients with moderate wart burdens, were utilized for cost-comparison analyses. Based on the cost analysis model, the least expensive treatment option for non-genital warts were carbon dioxide laser therapy (157 dollars) and Candida antigen injections (190 dollars). The other treatment modalities examined ranged from 495 dollars (bleomycin) to 1227 dollars (interferon alpha). Although treatment with the carbon dioxide laser therapy is the least expensive, pain and post-procedure complications limit the use of this modality.

OBJECTIVE The potential benefits of continuous glucose monitoring (CGM) in the management of adults and children with well-controlled type 1 diabetes have not been examined. RESEARCH DESIGN AND METHODS A total of 129 adults and children with intensively treated type 1 diabetes (age range 8-69 years) and A1C <7.0% were randomly assigned to either continuous or standard glucose monitoring for 26 weeks. The main study outcomes were time with glucose level < or =70 mg/dl, A1C level, and severe hypoglycemic events. RESULTS At 26 weeks, biochemical hypoglycemia (< or =70 mg/dl) was less frequent in the CGM group than in the control group (median 54 vs. 91 min/day), but the difference was not statistically significant (P = 0.16). Median time with a glucose level < or =60 mg/dl was 18 versus 35 min/day, respectively (P = 0.05). Time out of range (< or =70 or >180 mg/dl) was significantly lower in the CGM group than in the control group (377 vs. 491 min/day, P = 0.003). There was a significant treatment group difference favoring the CGM group in mean A1C at 26 weeks adjusted for baseline (P < 0.001). One or more severe hypoglycemic events occurred in 10 and 11% of the two groups, respectively (P = 1.0). Four outcome measures combining A1C and hypoglycemia data favored the CGM group in comparison with the control group (P < 0.001, 0.007, 0.005, and 0.003). CONCLUSIONS Most outcomes, including those combining A1C and hypoglycemia, favored the CGM group. The weight of evidence suggests that CGM is beneficial for individuals with type 1 diabetes who have already achieved excellent control with A1C <7.0%.

Children were virilized by contact with adults using cutaneous steroid preparations. Parents were unaware of the dangers of passive transfer. Laboratory data were consistent with exogenous androgen exposure. Each child had opportunity for passive exposure, and discontinuation of contact resulted in a decrease of androgen levels or regression of symptoms.
