RESUMO

Facioscapulohumeral muscular dystrophy (FSHD) is characterized by incomplete penetrance and intra-familial clinical variability. The disease has been associated with the genetic and epigenetic features of the D4Z4 repetitive elements at 4q35. Recently, D4Z4 hypomethylation has been proposed as a reliable marker in the FSHD diagnosis. We exploited the Italian Registry for FSHD, in which FSHD families are classified using the Clinical Comprehensive Evaluation Form (CCEF). A total of 122 index cases showing a classical FSHD phenotype (CCEF, category A) and 110 relatives were selected to test with the receiver operating characteristic (ROC) curve, the diagnostic and predictive value of D4Z4 methylation. Moreover, we performed DNA methylation analysis in selected large families with reduced penetrance characterized by the co-presence of subjects carriers of one D4Z4 reduced allele with no signs of disease or presenting the classic FSHD clinical phenotype. We observed a wide variability in the D4Z4 methylation levels among index cases revealing no association with clinical manifestation or disease severity. By extending the analysis to family members, we revealed the low predictive value of D4Z4 methylation in detecting the affected condition. In view of the variability in D4Z4 methylation profiles observed in our large cohort, we conclude that D4Z4 methylation does not mirror the clinical expression of FSHD. We recommend that measurement of this epigenetic mark must be interpreted with caution in clinical practice.

RESUMO

BACKGROUND AND AIMS: Patients presenting with nonhematemesis GI bleeding (NHGIB) represent a diagnostic challenge for physicians. We performed a randomized controlled trial to assess the benefits of deployment of a video capsule soon after admission in the management of patients presenting with melena, hematochezia, or severe anemia compared with standard of care management. METHODS: Patients admitted with NHGIB were randomized and placed into 1 of 2 study groups. In the experimental group, patients ingested a video capsule soon after admission to the hospital. These patients had further endoscopic workup based on the findings from the capsule. Patients in the control group underwent endoscopic evaluation (ie, upper endoscopy, capsule endoscopy, and/or colonoscopy) to identify the source of bleeding as directed by the attending gastroenterologist's interpretation of their clinical presentation. The primary endpoint for this study was the rate of localization of bleeding during hospitalization. RESULTS: Eighty-seven patients were included in this study: 45 randomized to the standard of care arm and 42 to the early capsule arm. A bleeding source was localized in 64.3% of the patients in the early capsule arm and in 31.1% of the patients in the standard of care arm (P < .01). The likelihood of endoscopic localization of bleeding over time was greater for patients receiving early capsule endoscopy compared with those in the standard of care arm (adjusted hazard ratio, 2.77; 95% confidence interval, 1.36-5.64). CONCLUSIONS: For patients admitted to the hospital for NHGIB, early capsule endoscopy is a safe and effective alternative for the detection of the source of bleeding.

RESUMO

BACKGROUND: Location of bleeding can present a diagnostic challenge in patients without hematemesis more so than those with hematemesis. AIM: To describe endoscopic diagnostic yields in both hematemesis and non-hematemesis gastrointestinal bleeding patient populations. METHODS: A retrospective analysis on a cohort of 343 consecutively identified gastrointestinal bleeding patients admitted to a tertiary care center emergency department with hematemesis and non-hematemesis over a 12-month period. Data obtained included presenting symptoms, diagnostic lesions, procedure types with diagnostic yields, and hours to diagnosis. RESULTS: The hematemesis group (n = 105) took on average 15.6 h to reach a diagnosis versus 30.0 h in the non-hematemesis group (n = 231), (p = 0.005). In the non-hematemesis group, the first procedure was diagnostic only 53% of the time versus 71% in the hematemesis group (p = 0.02). 25% of patients in the non-hematemesis group required multiple procedures versus 10% in the hematemesis group (p = 0.004). Diagnostic yield for a primary esophagogastroduodenoscopy was 71% for the hematemesis group versus 50% for the non-hematemesis group (p = 0.01). Primary colonoscopies were diagnostic in 54% of patients and 12.5% as a secondary procedure in the non-hematemesis group. A primary video capsule endoscopy yielded a diagnosis in 79% of non-hematemesis patients (n = 14) and had a 70% overall diagnostic rate (n = 33). CONCLUSION: Non-hematemesis gastrointestinal bleeding patients undergo multiple non-diagnostic tests and have longer times to diagnosis and then compared those with hematemesis. The high yield of video capsule endoscopy in the non-hematemesis group suggests a role for this device in this context and warrants further investigation.

RESUMO

BACKGROUND: Current practice for diagnosing neonatal abstinence syndrome and guiding pharmacological management of neonatal drug withdrawal is dependent on nursing assessments and repeated evaluation of clinical signs. PURPOSE: This single-center quality improvement initiative was designed to improve accuracy and consistency of Finnegan scores among neonatal nurses. METHODS: One-hundred seventy neonatal nurses participated in a single-session withdrawal-assessment program that incorporated education, scoring guidelines, and a restructured Finnegan scale. Nurses scored a standardized video-recorded infant presenting with opioid withdrawal before and after training. RESULTS: Nearly twice as many nurses scored at target (Finnegan score of 8) posttraining (34.7%; mean error = 0.559, SD = 1.4) compared with pretraining (18.8%; mean error = 1.31, SD = 1.95; Wilcoxon, P < .001). Finnegan scores were significantly higher than the target score pretraining (mean = 9.31, SD = 1.95) compared with posttraining (mean = 8.56, SD = 1.40, Wilcoxon P < .001); follow-up assessments reverted to pretraining levels (mean = 9.16, SD = 1.8). Score dispersion was greater pretraining (variance 3.80) compared with posttraining (variance 1.96; Kendall's Coefficient, P < .001) largely due to score disparity among central nervous system symptomology. IMPLICATIONS FOR PRACTICE: Education, clinical guidelines, and a restructured scoring tool increased consistency and accuracy of infant withdrawal-assessments among neonatal nurses. However, more than 60% of nurses did not assess withdrawal to the target score immediately following the training period and improvements did not persist over time. IMPLICATIONS FOR RESEARCH: This study highlights the need for more objective tools to quantify withdrawal severity given that assessments are the primary driver of pharmacological management in neonatal drug withdrawal.Video Abstract available at https://journals.lww.com/advancesinneonatalcare/Pages/videogallery.aspx.

RESUMO

Differentiation between psychogenic nonepileptic seizures (PNES) and generalized convulsive epileptic seizures (ES) is important for appropriate triaging in the emergency department (ED). This can be difficult in the ED, as the event is often not witnessed by a medical professional. In the current study, we investigated whether anion gap (AG), bicarbonate, and the Denver Seizure Score (DSS) could differentiate between PNES and ES. Of a total of 1,354 subjects reviewed from a tertiary care medical center, 27 PNES and 27 ES patients were identified based on clinical description and subsequent electroencephalogram. Multivariate logistic regression analysis and receiver operating characteristic curves were used to determine whether there was an association between seizure type and AG, bicarbonate, or DSS (24-bicarbonate + 2 × [AG-12]) when samples were drawn within 24 h of the concerning event. The result showed that sensitivity and negative predictive value dropped markedly for all measures if samples were drawn >2 h after the event; the sensitivity was similar for AG and DSS and higher than for bicarbonate. We propose that AG > 10 (sensitivity of 81.8%, specificity of 100%) in the first 2 h after the event could be used as a potential tool in the ED to help differentiate between PNES and ES.

RESUMO

STUDY OBJECTIVE: Prolonged boarding times in the emergency department (ED) disproportionately affect mental health patients, resulting in patient and provider dissatisfaction and increased patient morbidity and mortality. Our objective is to quantify the burden of mental health boarding and to elucidate the effect of insurance together with demographic, social, and comorbid factors on length of stay. METHODS: We conducted a cross-sectional observational study of 871 consecutive patients requiring an ED mental health evaluation at one of 10 unaffiliated Massachusetts hospitals. Demographics; insurance; length of stay; medical, psychiatric, and social history; and disposition data were collected. We evaluated the effect of these characteristics on boarding time. RESULTS: ED median length of stay varied greatly by disposition, driven primarily by ED boarding time. Admitted and transferred patients had longer delays than discharged patients (5.63, 9.32, and 1.23 hours, respectively). Medical clearance time (1.40 hours) composed only 10.5% of total ED length of stay and varied little by insurance. In our multivariate analyses, patients with Medicaid and the uninsured had significantly longer total lengths of stay and were more than twice as likely to remain in the ED for 24 hours or greater compared with privately insured patients. CONCLUSION: Mental health patients in Massachusetts have lengthy ED visits, particularly those requiring inpatient admission. Boarding time accounts for the majority of total ED length of stay and varies by insurance, even when other factors known to affect ED length of stay are controlled. Efforts to improve timeliness of care for mental health emergencies should focus on reducing ED boarding and eliminating disparities in care by insurance status.

RESUMO

OBJECTIVE: To assess the reproducibility and repeatability of an optical coherence tomography (OCT) device for imaging the optic nerve region of normal canines. ANIMALS STUDIED: Twelve clinically healthy beagles. PROCEDURES: All animals were anesthetized, and an OCT device was used to image the optic disk region. Total disk area and retinal nerve fiber layer (NFL) thickness in eight segments were obtained from each image. Images were collected by two operators in succession and each operator took five scans, repositioning the device between measurements. B-scan segmentations and disk outlines were subsequently redrawn to obtain manual measurements, allowing for comparisons between automated measurements. RESULTS: Operator 1 had a mean (±SD) NFL thickness (automatic) and disk area of 73.38 ± 7.41 µm and 3.69 ± 0.52 mm², while operator 2 had 74.27 ± 7.33 µm and 3.67 ± 0.51 mm², respectively. With manual corrections, operator 1 had a NFL thickness and disk area of 86.19 ± 8.26 µm and 3.74 ± 0.68 mm², while operator 2 had 86.85 ± 6.91 µm and 3.81 ± 0.56 mm², respectively. Operators did not obtain significantly different values for any region. Intraclass correlation ranged from 0.33 to 0.97 (average 0.78). Coefficient of variation ranged from 8.8 to 36.2%. CONCLUSION: The OCT device demonstrated high inter-rater reliability. Intrarater reliability was strong for disk area and total NFL; however, the segmental regions demonstrated a higher degree of variability. Manual and automated measurements were significantly different for total NFL and some segmental regions; therefore, users should consistently use one method for longitudinal studies.

RESUMO

Discovering how to improve survival and establishing clinical reference points for children diagnosed with endemic Burkitt lymphoma (eBL) in resource-constrained settings has recaptured international attention. Using multivariate analyses, we evaluated 428 children with eBL in Kenya for age, gender, tumor stage, nutritional status, hemoglobin, lactate dehydrogenase (LDH), Epstein-Barr virus (EBV) and Plasmodium falciparum prior to induction of chemotherapy (cyclophosphamide, vincristine, methotrexate and doxorubicin) to identify predictive and prognostic biomarkers of survival. During this 10 year prospective study period, 22% died in-hospital and 78% completed six-courses of chemotherapy. Of those, 16% relapsed or died later; 31% achieved event-free-survival; and 31% were lost to follow-up; the overall one-year survival was 45%. After adjusting for covariates, low hemoglobin (<8 g/dL) and high LDH (>400 mU/ml) were associated with increased risk of death (adjusted Hazard Ratio (aHR) = 1.57 [0.97-2.41]) and aHR = 1.84, [0.91-3.69], respectively). Anemic children with malaria were 3.55 times more likely to die [1.10-11.44] compared to patients without anemia or malarial infection. EBV load did not differ by tumor stage nor was it associated with survival. System-level factors can also contribute to poor outcomes. Children were more likely to die when inadvertently overdosed by more than 115% of the correct dose of cyclophosphamide (a HR = 1.43 [0.84-2.43]) or doxorubicin (a HR = 1.25, [0.66-2.35]), compared with those receiving accurate doses of the respective agent in this setting. This study codifies risk factors associated with poor outcomes for eBL patients in Africa and provides a benchmark by which to assess improvements in survival for new chemotherapeutic approaches.

RESUMO

HIV vaccine trials with minors will likely require parental permission and informed assent from adolescents. For this to be a valid process, the information needs to be presented in a manner that promotes adolescent comprehension. Previous studies suggest that adolescent comprehension of assent is often insufficient. We developed an interactive web-based assent that included interspersed quiz questions for a hypothetical HIV vaccine trial. Efficacy of the web-based assent was compared to a standard paper assent with and without interspersed questions. One hundred twenty teen participants, ages 15-17 years, from five community organizations were randomized to self-administered web-based assent (n=60) or investigator-administered paper assent with (n=29) or without (n=31) interspersed quiz questions. After reviewing the assent, participants completed a 27-item comprehension test. Comprehension scores were compared between groups. The mean number of correctly answered questions were 21.2 for the full paper group and 21.1 for the web-based group (t118=-0.08, p=0.94). Scores were 20.2 for the paper without interspersed questions sub-group and 22.1 for the paper with interspersed questions sub-group (t58=1.96, p=0.055). Participants in the web-based group performed as well on the comprehension test as those in the paper group, and those in the paper with questions sub-group performed better than those in the paper without questions sub-group, suggesting that interspersed quiz questions may improve understanding of a traditional paper assent. The minimal investigator time and standardized administration of the web-based assent as well as ability to tailor the assent discussion to topics identified by incorrect comprehension test responses are advantages worthy of further investigation.

RESUMO

BACKGROUND: The combined effects of nutrient malabsorption and adiposity on vitamin D status are unclear in pediatric malabsorption syndromes. AIM: To determine the relationship between adiposity and serum 25-hydroxyvitamin D (25(OH)D) in malabsorption disorders. METHODS: Prepubertal children of ages 3-12 with either lactose intolerance (LI) (n = 38, age 8.61 ± 3.08, male/female 19/19), or celiac disease (CD) (n = 24) were compared to healthy controls (n = 49, age 7.95 ± 2.64, male/female 28/21). A separate cohort of combined prepubertal and pubertal subjects with inflammatory bowel disease (IBD) (n = 59, age 16.4 ± 2.2, male/female 31/27) were also compared to healthy controls (n = 116, male/female 49/67, age 14.6 ± 4.4). Vitamin D deficiency was defined as 25(OH)D of <50 nmol/l, overweight as body mass index (BMI) of ≥ 85th but <95th percentile, and obesity as BMI ≥ 95th percentile. RESULTS: Among the controls, 25(OH)D was significantly higher in the normal-weight prepubertal controls vs. the overweight/obese controls (p = 0.001), and similarly so for the combined cohort of prepubertal and pubertal controls (p = 0.031). In contrast, there was no significant difference in 25(OH)D concentration between the normal-weight vs. overweight/obese patients with LI (p = 0.335), CD (p = 0.387), and IBD (p = 0.883). CONCLUSION: There is no association between adiposity and serum 25(OH)D in pediatric malabsorption syndromes.

RESUMO

Disorders of the stifle are a common cause of lameness in horses yet the accuracy of scintigraphy for diagnosis of stifle conditions is controversial. The aim of retrospective cross-sectional study was to determine the diagnostic sensitivity (Se) of bone scintigraphy in detecting stifle disease and to determine if two orthogonal scintigraphic images improve diagnostic Se. Horses that underwent scintigraphic examination during a two-year period were included. Horses were divided into two groups: group 1 (N = 23) had lameness that was localized to the stifle by intra-articular analgesia and group 2 (N = 182) had lameness that was localized to a different location. Scintigraphic studies (one image or two images) were independently and retrospectively analyzed by two radiologists (R1 and R2). Sensitivity, specificity (Sp) and predictive values (PV), and were calculated for each type of study (one image or two images) and for each radiologist (R1 or R2). The Se to detect stifle disorders varied between radiologists (29.2% and 20.8%). The Sp was 84.5% and 88.3%. When two images were evaluated a decrease in the positive PV for both readers occurred. The Cohen kappa coefficient (κ) between readers was poor when one image (0.084) or two images (0.117) were evaluated. Findings from this study indicated that bone-phase nuclear scintigraphy is reasonably specific but highly insensitive for detecting lameness originating from the stifle in a diverse population of both normal and affected horses. The addition of a caudal scintigraphic image acquisition did not improve diagnostic sensitivity.

RESUMO

BACKGROUND: There is no consensus on the association between vitamin D and asthma. OBJECTIVE: To determine the relationship between 25-hydroxyvitamin D [25(OH)D] levels and asthma symptom severity in children and adolescents. METHODS: A retrospective, case-control study of 263 subjects of ages 2-19 years with asthma who were compared to 284 non-asthmatic controls of similar ages. Subjects were excluded if they had diseases of calcium or vitamin D metabolism or were receiving calcium or vitamin D supplementation. Serum 25(OH)D was measured in all subjects. Asthma symptom severity, usually stratified into 6 steps, was stratified into five steps [1-5] based on the number and dose of controller medications used as outlined by the National Heart, Lung, and Blood Institute's guidelines. Mean 25(OH)D values were compared between the asthmatic patients and controls, as well as among the five steps of asthma symptom severity. Results were adjusted for age, sex, BMI, race and severity of asthma symptoms. RESULTS: There was no difference in 25(OH)D between asthmatic patients and controls (28.64 +/- 10.09 vs. 28.42 +/- 11.47, p = 1.0). However, there was a significant difference in 25(OH)D between obese and non-obese asthmatic patients (23.33 +/- 7.67 vs. 30.16 +/- 10.20, p < 0.0001), as well as obese and non-obese controls (24.56 +/- 9.90 vs. 29.50 +/- 11.66, p = 0.003). Mean 25(OH)D levels did not vary significantly among the five steps of asthma symptom severity. CONCLUSIONS: There were no differences in mean 25(OH) D levels between asthmatic patients and controls. Mean 25(OH)D level was significantly lower in both the obese asthmatic patients and obese controls. Asthma severity had no relationship to mean 25(OH)D levels.

RESUMO

BACKGROUND: Celiac disease (CD) is an autoimmune enteropathy characterized by villus atrophy and malabsorption of essential nutrients. Vitamin D deficiency has been described in autoimmune diseases, but its status in prepubertal children with CD has not been adequately studied. OBJECTIVE: To determine the vitamin D status of prepubertal children with CD. STUDY DESIGN: A retrospective study of prepubertal children aged 3-12 years with CD (n=24) who were compared to prepubertal, non-CD children of the same age (n=50). Children were included in the study if they had a diagnosis of CD by intestinal biopsy, and were not on a gluten-free diet (GFD). Patients were excluded if they had diseases of calcium or vitamin D metabolism, or were receiving calcium or vitamin D supplementation or had other autoimmune diseases. All subjects had their serum 25-hydroxyvitamin D [25(OH)D] level measured. RESULTS: There was no difference in 25(OH)D level between the CD and non-CD children (27.58 +/- 9.91 versus 26.20 +/- 10.45, p = 0.59). However, when the patients were subdivided into obese and non-obese groups, the non-obese CD patients had a significantly higher 25(OH)D level than the obese normal children (28.39 +/- 10.26 versus 21.58 +/- 5.67, p = 0.009). In contrast, there was no difference in 25(OH)D level between non-obese CD patients and non-obese normal children (28.39 +/- 10.26 versus 30.64 +/-12.08, p = 0.52). The season of 25(OH)D measurement was not a significant confounder (p =0.7). CONCLUSIONS: Our data showed no difference in 25(OH) D levels between normal children and those with CD when adjusted for body mass index.

RESUMO

BACKGROUND/AIMS: The effect of the rising prevalence of nonalcoholic fatty liver disease on the 25-hydroxylation of pre-vitamin D in the liver, and consequent glycemic control in children with diabetes mellitus is not known. Our aim was to determine whether mild hepatic dysfunction was associated with impaired 25-hydroxylation of pre-vitamin D, and if this vitamin D deficiency was associated with impaired glycemic control in children and adolescents with type 1 diabetes (T1DM) and type 2 diabetes (T2DM). METHODS: We analyzed simultaneously measured HbA1c, ALT, AST, and 25OHD levels and clinical parameters in 121 children and adolescents with T1DM (n=81) and T2DM (n=40). The subjects, ages 11-21 years, all had diabetes of >6 months duration. Multivariate linear regression was used to analyze the associations, while comparisons between subgroups were made using two-tailed Student's t-test. RESULTS: Vitamin D deficiency (25OHD <15 ng/mL (37.5 nmol/L) was more prevalent in T2DM patients (47.5%) compared to T1DM patients (18.5%). Subjects with T2DM had significantly elevated transaminases (AST 39.3 +/- 2.0 vs. 22.4 +/- 1.4, p<0.001; ALT 30.6 +/- 1.8 vs. 18.7 +/- 1.3, p<0.001) compared to TIDM patients, and demonstrated a significant inverse relationship between their HbA1c and 25OHD levels (beta=-0.42, p=0.02), compared to T1DM subjects (beta=-0.06, p=0.62). CONCLUSIONS: The association of elevated ALT with vitamin D deficiency suggests that hepatic dysfunction could impair vitamin D metabolism and negatively impact glycemic control in youth with T2DM.

RESUMO

OBJECTIVES: The objective of this study was to determine whether the use of heated, humidified, high-flow nasal cannula (HFNC) therapy is associated with a decreased need for intubation in patients presenting to a pediatric emergency department (PED) and admitted to a pediatric intensive care unit (PICU) with acute respiratory insufficiency (ARI). METHODS: A retrospective study of all patients admitted from the PED to the PICU with ARI from January 2006 through December 2009. Patients admitted before the availability of HFNC (cohort 1) were compared with those admitted after the availability of HFNC but before implementation of an institution-wide guideline on pediatric HFNC usage (cohort 2) and those admitted after the implementation of a pediatric HFNC usage guideline (cohort 3). RESULTS: After controlling for age, month of admission, type of respiratory illness, and severity of illness, there was an 83% reduction in the odds of intubation in the PED in cohort 3 compared with cohort 1 (odds ratio, 0.17; 95% confidence interval, 0.06-0.50; P = 0.001). There was no significant change in mortality or median PICU length of stay after the introduction of HFNC. CONCLUSIONS: High-flow nasal cannula used early in the development of pediatric ARI is associated with a decreased the need for intubation and mechanical ventilation.

RESUMO

BACKGROUND: To assess the effectiveness of a mobile injury prevention vehicle (mobile safety street [MSS]) with a hands-on curriculum on instruction and retention of safety knowledge compared with traditional classroom safety curriculum among grade 5 elementary school children. METHODS: Grade 5 students (n = 1,692) were asked to participate in the study as either the intervention group (MSS experience) or the comparison group (traditional classroom safety curriculum). Each student in the intervention group was asked to complete a series of three surveys. The first survey was given before the MSS visit (Fall 2009), the second immediately following the MSS visit (Fall 2009), and a third given 6 months after the MSS visit (Spring 2010) to measure knowledge retention. Students in the comparison group were asked to complete two surveys. The first survey was given at the same time as the intervention group (Fall 2009) and the second was given after the completion of the traditional classroom safety curriculum (Spring 2010). RESULTS: Students scored on average 5.67 of 10 (5.56-5.80) before any safety instruction was given. After MSS instruction, mean scores showed a significant increase to 7.43 of 10 (7.16-7.71). Such increase was still measurable 6 months after the intervention 7.34 (7.04-7.66). The comparison group saw a significant increase in their mean scores 6.48 (6.10-6.89), but the increase was much smaller than the intervention group. CONCLUSIONS: Community-based injury prevention programs are essential to reducing preventable injury and deaths from trauma. This study demonstrates that a hands-on program is more effective than traditional methods for providing safety knowledge.

RESUMO

BACKGROUND: US children aged between 5 years and 14 years have a rate of gun-related homicide 17 times higher and a rate of gun-related suicide and unintentional firearm injury 10 times higher than other developed countries. Gun buyback programs have been criticized as ineffective interventions in decreasing violence. The Injury Free Coalition for Kids-Worcester (IFCK-W) Goods for Guns buyback is a multipronged approach to address these concerns and to reduce the number of firearms in the community. METHODS: The IFCK-W buyback program is funded by corporate sponsors, grants, and individual donations. Citizens are instructed to transport guns, ammunition, and weapons safely to police headquarters on two Saturdays in December. Participants are guaranteed anonymity by the District Attorney's office and receive gift certificates for operable guns. Trained volunteers administer an anonymous survey to willing participants. Individuals who disclose having unsafely stored guns remaining at home receive educational counseling and trigger locks. Guns and ammunition are destroyed at a later time in a gun crushing ceremony. RESULTS: Since 2002, 1,861 guns (444 rifle/shotgun, 738 pistol/revolver, and 679 automatic/semiautomatic) have been collected at a cost of $99,250 (average, $53/gun). Seven hundred ten people have surrendered firearms, 534 surveys have been administered, and ≈ 75 trigger locks have been distributed per year. CONCLUSIONS: IFCK-W Goods for Guns is a relatively inexpensive injury prevention model program that removes unwanted firearms from homes, raises community awareness about gun safety, and provides high-risk individuals with trigger locks and educational counseling.

RESUMO

Second-generation antipsychotic (SGA) medications introduced about 20 years ago are increasingly used to treat psychiatric illnesses in children and adolescents. There has been a five-fold increase in the use of these medications in U.S. children and adolescents in the past decade. However, there has also been a parallel rise in the incidence of side effects associated with these medications, such as obesity, dyslipidemia, insulin resistance, and diabetes mellitus. Despite the severity of these complications and their financial impact on the national healthcare budget, there is neither a clear understanding of the mechanisms contributing to these side effects nor the best ways to address them. Studies that examined lifestyle modification and pharmaceutical agents have yielded mixed results. Therefore, clinical studies using agents, such as vitamin D, which are inexpensive, readily available, with low side effects profile, and have mechanisms to counteract the metabolic side effects of SGA agents, are warranted. Vitamin D is a prohormone with skeletal and extraskeletal properties that could potentially reduce the severity of these metabolic side effects. Its role as an adjunctive therapy for the management of metabolic side effects of SGA agents has not been adequately studied. Effective strategies to curb these side effects will improve the overall health of youths with psychiatric illnesses who receive SGAs. Herein we present a pilot study on the use of vitamin D in patients on treatment with SGAs.

RESUMO

OBJECTIVE: Evaluate the influence of topically applied flurbiprofen 0.03% and latanoprost 0.005%, alone or in combination, in normal canines. ANIMALS STUDIED: 10 Normal Beagles. PROCEDURES: Intraocular pressure (IOP), pupil size, aqueous flare, conjunctival hyperemia, and blepharospasm were evaluated bilaterally five times daily (8 am, 11 am, 2 pm, 5 pm, and 8 pm). The study consisted of a training and acclimation period, followed by 3, 1-week experiment periods. A 2-week washout period occurred between each experiment period. During period 1, all dogs received flurbiprofen (three doses 6-h apart) in the treated eye, whereas in period 2, all dogs received latanoprost (one dose 24-h apart). During period 3, both latanoprost (one dose 24-h apart) and flurbiprofen (three doses 6-h apart) were administered in the treated eye. RESULTS: Flurbiprofen resulted in a mean IOP elevation of 1.1 mmHg (8.65%) in the treated eye, as compared with the control eye. No effect on pupil size, conjunctival hyperemia, or aqueous flare was noted. Latanoprost resulted in a mean IOP reduction of 3.4 mmHg (30.19%). Combined latanoprost and flurbiprofen resulted in a mean IOP reduction of 2.7 mmHg (24.56%). Miosis was noted in the treated eyes during both latanoprost periods, with maximal pupil constriction 3-h post-dose. This was followed by relative mydriasis 24-h post-dose, persisting 48 h after the last dose. The degree of conjunctival hyperemia varied between individuals. Neither blepharospasm nor aqueous flare was noted at any time point. CONCLUSION: Concurrent administration of latanoprost and flurbiprofen resulted in a 20.41% reduction in the ocular hypotensive effect relative to latanoprost therapy alone.

RESUMO

OBJECTIVE: To analyze factors associated with interdog household aggression and determine treatment outcomes. DESIGN: Retrospective case series and survey. Animals-38 pairs of dogs with interdog household aggression. Each pair of dogs was considered 1 case. PROCEDURES: Records of dogs with interdog household aggression that were examined during initial or follow-up consultations at a veterinary teaching hospital from December 5, 2006, to December 5, 2007, were analyzed for clinical features. Data regarding outcome, owner compliance, and efficacy of recommended treatments obtained by use of a follow-up survey were evaluated. RESULTS: Most cases (30/38 [79%]) of interdog household aggression involved same-sex pairs; 26 of 38 (68%) cases involved 1 female or a pair of females. Instigators and recipients of aggression were clearly identified in 27 of 38 (71%) cases; most instigators were the younger of the pair (20/27 [74%]) or were newer additions to the household (19/27 [70%]). Fight-eliciting triggers included owner attention, food, excitement, and found items. Some dogs had risk factors for behavior problems such as a history of living in multiple households (21/51 [41%]), adoption after 12 weeks of age (20/51 [39%]), or being acquired from a shelter (17/51 [33%]). Effective treatment recommendations included implementing a so-called nothing-in-life-is-free program, giving 1 dog priority access to resources, and administering psychotropic medication. Frequency and severity of fighting were significantly reduced after consultation. Owners reported a 69% overall improvement following treatment. CONCLUSIONS AND CLINICAL RELEVANCE: Most treatment strategies were considered effective. Consistency and predictability of social interactions are essential in resolving interdog household aggression.
