ABSTRACT
Arteriovenous fistula formation after a closed extremity fracture is rare. We present the case of an 11-year-old boy who developed an arteriovenous fistula between the anterior tibial artery and popliteal vein after closed fractures of the proximal tibia and fibula. The fractures were treated by closed reduction and casting. A fistula was diagnosed 12 weeks after the injury. It was treated by embolisation with coils. Subsequent angiography and ultrasonography confirmed patency of the popliteal vein and anterior and posterior tibial and peroneal arteries, with no residual shunting through the fistula. The fractures healed uneventfully and he returned to full unrestricted activities 21 weeks after his injury.

The health benefits of exercise may be attenuated by sports and recreation related injury (SRI). Though the majority of SRI are mild and self-limiting, a significant number are serious and require orthopaedic intervention. The aims of this study were to assess the burden of these serious injuries on the orthopaedic inpatient service, and to investigate potential target areas for injury prevention. All 1,590 SRI seen in the ED over a 3-month period were analysed using the Patient Information Management System to determine which patients received inpatient orthopaedic care. The medical records of those 63 patients who required inpatient care under orthopaedics were reviewed and data collected on demographic features, history, operative procedure and theatre resources, and length of hospital stay. Data were analyzed using SPSS. SRI accounted for 12.3% of all ED presentations. The principal activities resulting in injury requiring orthopaedic care were soccer, hurling and informal play e.g. trampoline. Falls made up 37% of the overall mechanism of injury but 68% of the injuries severe enough to require operative management. Most operative procedures were performed as part of a routine day trauma list but 20% were performed out of hours. This group of injuries places a significant burden on a busy trauma service. Injury prevention measures such as public education regarding falls in sport may have a role in reducing this burden.

BACKGROUND: The acutely limping child presents a significant diagnostic challenge. AIM: The purpose of this study was to create a clinically useful algorithm to allow exclusion of 'musculoskeletal sepsis' as a differential diagnosis in the child presenting with limp. METHODS: Data were collected on all 286 limping children admitted to our centre over a 3-year-period. Using logistic regression analysis, the predictive model was constructed, to exclude infection. RESULTS: Duration of symptoms, constitutional symptoms, temperature, white cell count and ESR were significantly different in children with musculoskeletal infection (P < 0.05). Multivariate analysis demonstrated that when all three variables of duration of symptoms >1, <5 days; temperature >37.0 degrees C; and ESR >35 mm/h were present, the predicted probability of infection was 0.66, falling to 0.01 when none were present. CONCLUSION: This multivariate model enables us to rule out musculoskeletal infection with 99% certainty in limping children with none of these three presenting variables.

OBJECTIVE: We investigated the heat stability of six common therapeutic drugs routinely assayed in pharmacokinetic and clinical laboratories. DESIGN: Serum samples were spiked at three concentrations (subtherapeutic, therapeutic, and potentially toxic) with amikacin, gentamicin, tobramycin, phenytoin, theophylline, and phenobarbital. The samples were then heated at 56 degrees C and assayed by fluorescence polarization immunoassay at 15-minute intervals for one hour. SETTING: The study was conducted at a clinical research laboratory using standard laboratory methods. MAIN OUTCOME MEASURES: Drug concentrations of heated samples were compared with unheated controls using ANOVA to determine if degradation occurred over time with heating. RESULTS: Analysis of data revealed no degradation of any of the samples. CONCLUSIONS: Heat treatment of samples from high-risk individuals may be a mechanism to protect healthcare workers from exposure to the human immunodeficiency virus.

A case of pseudo-tumor cerebri is reported in a woman being treated with minocycline and tretinoin for acne who also ingested liver as a self-treatment for her condition. A possible cumulative effect between these agents is postulated.

We present a case of acute dystonia caused by administration of etoposide in an 11-year-old boy being treated for acute lymphoblastic leukemia. We believe this is the first report of this side effect.
