Confirmation that Child Behavior Checklist clinical scales discriminate juvenile mania from attention deficit hyperactivity disorder

OBJECTIVE: To determine whether boys meeting diagnostic criteria for juvenile mania and attention deficit hyperactivity disorder (mania-ADHD) may be distinguished from boys with ADHD alone on a range of clinical and family variables. METHODOLOGY: Boys aged 9-13 years with mania-ADHD (n = 25), ADHD alone (n = 99), or no psychiatric diagnosis (n = 27) were compared on parent and teacher report Child Behavior Checklists (CBCL) and Conners Questionnaires, self-report CBCLs, patterns of comorbidity, intellectual functioning, and family variables. RESULTS: Mania-ADHD subjects had significantly higher mean ratings than ADHD only subjects on the parent CBCL for the Withdrawn, Thought Problems, Delinquent Behavior and Aggressive Behavior scales and significantly higher rates of comorbid depression, anxiety and psychotic symptoms. Other variables did not distinguish the mania-ADHD and ADHD only groups. CONCLUSIONS: These data confirm previous research indicating that the CBCL may be used to assist in the clinical identification of manic children.     

Influence of the limited interchange rule on injury rates in sub-elite Rugby league players

This study investigated the incidence of injury in sub-elite Rugby League players before and after the introduction of the limited interchange rule. The incidence of injury was prospectively studied in one sub-elite Rugby League club over three competitive seasons. Two seasons were played under the unlimited interchange rule, while the third season was played under the limited interchange rule. Players participated in 91 matches under the unlimited interchange rule and 44 matches under the limited interchange rule. Injury was defined as any pain, disability or injury that occurred as a result of a competition game that caused the player to miss a subsequent game. The relative risk (RR) of injury significantly decreased (RR = 0.70 [0.65 to 0.75], P<0.05) following the introduction of the limited interchange rule, with the incidence of injury decreasing from 72.5 (58.2 to 86.8) per 1000 playing hr under the unlimited interchange rule to 51.0 (33.8 to 68.1) per 1000 playing hr under the limited interchange rule. The risk of sustaining thigh and calf injuries (RR= 0.27 [0.12 to 0.59], P < 0.05), muscular strains (RR= 0.23 10.17 to 0.31]., P<0.05), and high intensity running injuries (RR= 0.16 [0.04 to 0.691, P<0.05) was significantly reduced following the introduction of the limited interchange rule. These findings demonstrate that the risk of injury in sub-elite Rugby League players is significantly reduced following the introduction of the limited interchange rule. The reduced injury risk may reflect a fatigue-induced reduction in match speed and impact forces associated with physical collisions and tackles.     

Incidental Non-Inguinals Hernias in Totally Extra-Peritoneal Hernia Repair

Introduction

Totally extra-peritoneal (TEP) inguinal hernia repair allows identification and repair of incidental non-inguinal groin hernias. We assessed the prevalence of incidental hernias during TEP inguinal hernia repair and identified the risk factors for incidental hernias.

Materials and Methods

Consecutive patients undergoing TEP repair from May 2005 to November 2012 were the study cohort. Inspection for ipsilateral femoral, obturator and rarer varieties of hernia was undertaken during TEP repair. Patient characteristics and operative findings were recorded on a prospectively collected database.

Results

A total of 1,532 TEP repairs were undertaken in 1,196 patients. Ninety-three patients were excluded due to incomplete data, leaving 1,103 patients and 1,404 hernias for analyses (1,380 male; 802 unilateral and 301 bilateral repairs; median age, 59 years). Among the 37 incidental hernias identified (2.6% of cases), the most common type of incidental hernia was femoral (n=32, 2.3%) followed by obturator (n=2, 0.1%). Increasing age was associated with an increased risk of incidental hernia, with a significant linear trend (p<0.01). The risk for patients >60 years of age was 4.0% vs 1.4% for those aged <60 years (p<0.01). Incidental hernias were found in 29.2% of females vs 2.2% of males, (p<0.0001). Risk of incidental hernia in those with a recurrent inguinal hernia was 3.0% vs 2.6% for primary repair (p=0.79).

Conclusions

Incidental hernias during TEP inguinal hernia repair were found in 2.6% of cases and, though infrequent, could cause complications if left untreated. The risk of incidental hernia increased with age and was significantly higher in patients aged >60 years and in females.     

Angiographic ablation of parathyroid adenomas: lessons from a 10-year experience

Angiographic ablation of parathyroid adenomas with ionic contrast material was performed in 24 patients with persistent hyperparathyroidism who had undergone at least one prior unsuccessful surgical resection; 23 had mediastinal adenomas. The success rate was 83% at 1 month after ablation and 71% at both 5 and 9 years. Ablation was successful in 85% of the patients in whom the catheter could be wedged into the artery feeding the adenoma. Long-term success was achieved in 89% of the patients in whom contrast enhancement persisted in the adenoma on computed tomographic scans obtained 24 hours later. Acute complications were seen only in patients with glands supplied by the inferior or superior thyroid arteries. Long-term complications were limited to permanent hypocalcemia, present in 8% of patients. Even if unsuccessful for ablation, the procedure may provide localization and does not preclude surgical resection. It is recommended for most patients with persistent hyperparathyroidism and mediastinal adenomas, especially adenomas supplied by the internal thoracic artery.
