Frozen section pathology is routinely used for margin assessment of non‐melanoma skin cancer ( NMSC ). Frozen section can also be used for the primary diagnosis of several skin lesions. Limited data exist on the accuracy of frozen section in the diagnosis of NMSC . We performed a retrospective chart review of 300 cases in which frozen section diagnoses were compared with permanent section diagnoses of NMSC . Frozen section and permanent section pathology were concordant 83.3% of the time, with the highest concordance rates noted for basal cell carcinoma (145/153, 95%). Our results show a high level of concordance between frozen section and corresponding permanent section pathology diagnosis for NMSC . The rapidity of frozen section tissue processing and pathology reporting makes this technique useful in dermatologic practice for immediate diagnosis and management of NMSC . Further studies should explore strategies to decrease or eliminate discrepancies between frozen and permanent section diagnosis.

AbstractBackgroundPatients with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), or non‐Hodgkin lymphoma (NHL) are at increased risk for the development of skin malignancies.ObjectivesThis study was conducted to estimate the incidences of rare skin malignancies in patients with CLL/SLL or NHL.MethodsPatients with a diagnosis of CLL/SLL or NHL recorded in the Surveillance, Epidemiology and End Results (SEER) database during 1992–2007 were identified. Diagnoses of specific skin malignancies were identified from SEER files.ResultsDuring 1992–2007, a total of 128,674 patients with first diagnoses of CLL/SLL or NHL were recorded in SEER; 4743 were excluded because follow‐up data were unavailable. Among the remaining 123,931 patients, 28,964 had CLL/SLL and 94,967 had NHL. Standardized incidence ratios (SIRs) for invasive malignant melanoma, Merkel cell carcinoma, malignant fibrous histiocytoma, dermatofibrosarcoma protuberans, Kaposi's sarcoma, and sebaceous carcinoma were 2.3, 8.2, 3.6, 2.5, 2.9, and 1.4, respectively, in CLL/SLL patients and 1.6, 3.2, 1.5, 1.3, 17.6, and 0.8, respectively, in NHL patients. When invasive melanoma was stratified by patient age and sex, the highest SIR (17.8) was found in men aged 0–49 years with CLL (P < 0.001).ConclusionsPatients with CLL/SLL or NHL have a higher risk for the subsequent development of rare skin cancers. Given the more aggressive nature of these malignancies in this setting, regular monitoring for the development and prompt treatment of cutaneous malignancy is prudent in patients with NHL and particularly in patients with CLL. Regular use of sun protection may decrease the morbidity associated with skin cancer in this immunosuppressed population.

Objective: The purpose of our study was to compare the clinical utility of administering 2 recommended developmental screening instruments, the Infant Developmental Inventory (IDI) and the Ages and Stages Questionnaire (ASQ), at 9-month well-child visits in paper format. Methods: Outcomes of the 2 screens, including correct completion and interpretation by clinician, time of visit, and screen outcome were compared. Results: Out of 33 children administered the ASQ and with documented scores, 12 (36.4%) did not receive passing scores, while 5 (12.2%) of the 41 children administered the IDI did not receive passing scores ( P = .014). Out of 41 IDI screens, 12 (29.3%) were completed incorrectly, while there were no ASQ screens completed incorrectly ( P < .001) by caregivers. Conclusion: In our pilot study, the ASQ is more often completed correctly by caregivers and identifies more children at risk for delay as compared with the IDI. Additional larger scale studies are needed to evaluate the usefulness of developmental screening tools when used within primary care practice.

BACKGROUND AND OBJECTIVE:There is ongoing concern that stimulant medications may adversely affect growth. In a sample of attention-deficit/hyperactivity disorder (ADHD) cases and controls from a population-based birth cohort, we assessed growth and the association between stimulant treatment and growth.METHODS:Subjects included childhood ADHD cases (N = 340) and controls (N = 680) from a 1976 to 1982 birth cohort (N = 5718). Height and stimulant treatment information were abstracted from medical records and obtained during a prospective, adult follow-up study. For each subject, a parametric penalized spline smoothing method modeled height over time, and the corresponding height velocity was calculated as the first derivative. Peak height velocity (PHV) age and magnitude were estimated from the velocity curves. Among stimulant-treated ADHD cases, we analyzed height Z scores at the beginning, at the end, and 24 months after the end of treatment.RESULTS:Neither ADHD itself nor treatment with stimulants was associated with differences in magnitude of PHV or final adult height. Among boys treated with stimulants, there was a positive correlation between duration of stimulant usage before PHV and age at PHV (r = 0.21, P = .01). There was no significant correlation between duration of treatment and change in height Z scores (r = −0.08 for beginning vs end change, r = 0.01 for end vs 24 months later change). Among the 59 ADHD cases treated for ≥3 years, there was a clinically insignificant decrease in mean Z score from beginning (0.48) to end (0.33) of treatment (P = .06).CONCLUSIONS:Our findings suggest that ADHD treatment with stimulant medication is not associated with differences in adult height or significant changes in growth.

ABSTRACTObjective:The aim of the study was to determine whether docosahexaenoic acid (DHA) supplementation improves the behavior of children with autism.Methods:A group of 3‐ to 10‐year‐old children with autism were randomized in a double‐blind fashion to receive a supplement containing 200 mg of DHA or a placebo for 6 months. The parents and the investigator completed the Clinical Global Impressions‐Improvement scale to rate changes in core symptoms of autism after 3 and 6 months. The parents completed the Child Development Inventory and the Aberrant Behavior Checklist, and both parents and teachers completed the Behavior Assessment Scale for Children (BASC) at enrollment and after 6 months.Results:A total of 48 children (40 [83%] boys, mean age [standard deviation] 6.1 [2.0] years) were enrolled; 24 received DHA and 24 placebo. Despite a median 431% increase in total plasma DHA levels after 6 months, the DHA group was not rated as improved in core symptoms of autism compared to the placebo group on the CGI‐I. Based on the analysis of covariance models adjusted for the baseline rating scores, parents (but not teachers) provided a higher average rating of social skills on the BASC for the children in the placebo group compared to the DHA group (P = 0.04), and teachers (but not parents) provided a higher average rating of functional communication on the BASC for the children in the DHA group compared to the placebo group (P = 0.02).Conclusions:Dietary DHA supplementation of 200 mg/day for 6 months does not improve the core symptoms of autism. Our results may have been limited by inadequate sample size.

AbstractBackgroundWe examined the course of cutaneous T‐cell lymphoma (CTCL), which has been associated with chronic lymphocytic leukemia (CLL) in patients withCLL.Materials and methodsA search was conducted of the master diagnosis index at our institution to identify patients with bothCLLandCTCLfrom 1980 to 2010. A retrospective chart review was then conducted.ResultsOf the 14 patients withCTCLandCLL, eight had mycosis fungoides (MF; two with patch stage, two with plaque stage, two with tumor stage, and two with erythrodermic stage), four had Sézary syndrome, one had natural killer cell lymphoma involving the skin, and one had peripheral T‐cell lymphoma involving the skin. Eight had concurrent diagnoses, five received aCLLdiagnosis first, and one received aCTCLdiagnosis first. Ten patients were deceased at the time of data abstraction due to unknown causes (n = 4), lymphoma (n = 2), pneumonia (n = 2),MF(n = 1), or respiratory failure (n = 1). Of the nine patients with concurrent or priorCTCL, seven were deceased, with a median time to death of 10.2 months (range, 6–89 months). Of the five patients withCLLprior toCTCL, three were deceased at 18, 27, and 47 months, respectively, after theCTCLdiagnosis. The median survival for the two groups was 12 and 47 months, respectively.ConclusionsPatients withCTCLconcurrent with or prior toCLLhave a worse overall survival than patients withCLLin whomCTCLlater develops. Larger studies are needed.

BACKGROUND AND OBJECTIVE: Previous studies suggest that former late preterm infants are at increased risk for learning and behavioral problems compared with term infants. These studies have primarily used referred clinical samples of children followed only until early school age. Our objective was to determine the cumulative incidence of attention deficit/hyperactivity disorder (ADHD) and learning disabilities (LD) in former late preterm versus term infants in a population-based birth cohort. METHODS: Subjects included all children born 1976 to 1982 in Rochester, MN who remained in the community after 5 years. This study focused on the comparison of subjects in 2 subgroups, late preterm (34 to &lt;37 weeks) and term (37 to &lt;42 weeks). School and medical records were available to identify individuals who met research criteria for ADHD and LD in reading, written language, and math. The Kaplan-Meier method was used to estimate the cumulative incidence of each condition by 19 years of age. Cox models were fit to evaluate the association between gestational age group and condition, after adjusting for maternal education and perinatal complications. RESULTS: We found no statistically significant differences in the cumulative incidence of ADHD or LD between the late preterm (N = 256) versus term (N = 4419) groups: ADHD (cumulative incidence by age 19 years, 7.7% vs 7.2%; P = .84); reading LD (14.2% vs 13.1%; P = .57); written language LD (13.5% vs 15.7%; P = .36), and math LD (16.1% vs 15.5%; P = .89). CONCLUSIONS: These data from a population-based birth cohort indicate that former late preterm infants have similar rates of LD and ADHD as term infants.

Objective: To determine the temporal trends in diagnosis and management of pediatric overweight/obesity by primary care providers at a single medical center. Patients: Children 2 to 18 years old undergoing a general medical examination during 3 calendar years (2003, 2006, and 2009). The number of visits for general medical examination were 6390 in 2003, 6646 in 2006, and 7408 in 2009. Methods: We performed a retrospective review of the electronic medical records for weight related diagnostic and/or management terms and laboratory screening in children with body mass index at or greater than the 85th percentile (n = 1630 in 2003, 1495 in 2006, and 1730 in 2009). Results: There was a significant increase in the diagnosis of obesity among obese children seen in 2009 (53.3%) compared with 2006 (36%, P < .001) and 2003 (24.3%, P < .001). Weight-related counseling was documented in a higher proportion of obese children in 2009 (49.4%) compared with 2006 (34.8%) and 2003 (26.6%). There was a significant increase in counseling regarding screen time in 2009 compared with 2006. A significant increase in screening for nonalcoholic fatty liver disease was also noted (30.5% in 2009 vs 21.9% in 2006, P = .018). Conclusions: There has been steady improvement in the rates of obesity diagnosis and obesity-related counseling by primary care providers. However, continued efforts to increase awareness of these issues are needed as nearly half of obese children remained undiagnosed and recommended laboratory screening for obesity-related comorbidities was performed in only a third of obese children.
