RESUMEN
Due to increased gun availability/prevalence in current times, low-velocity firearm injuries have risen dramatically. This study describes the epidemiology of gunshot wounds (GSW) to the hand. We identified all patients (January 2005 - August 2015) who presented to our Level 1 trauma center with GSW's to the hand. Analysis of each record was performed to collect epidemiological variables. Cross-sectional analyses were performed to quantify the results. Following inclusion/exclusion criteria, 97 patients were selected. Individuals who sustained GSW's to the hand were typically male (93.8%) between the ages of 18 and 30 (48.5%). Injuries were mostly self-inflicted (81.4%), and isolated (89.7%) to the digits (55.7%) or metacarpals (35.1%) of the left hand (74.2%). Most were fired from BB/pellet guns (45.4%) or handguns (33.0%), while cleaning/loading them (65.1%). Over one-half of patients (58.8%) were uninsured. Surgery was required in 35.1% of patients. Patients shot with something other than a BB/Pellet gun (e.g., handgun, shotgun) required surgery significantly more than those shot with a BB/Pellet gun (P < 0.0001). An odds ratio further describing this relationship was 0.13 (P = 0.0002), reflecting an 87% reduction in the odds of surgery for individuals shot by a BB/pellet vs. a different type of gun. The typical GSW to the hand involves a middle-aged male receiving an isolated injury to the digits or metacarpals of the left hand, from a BB/Pellet gun or handgun while they are cleaning/loading the firearm. Patients sustaining injury by a BB/pellet gun are least likely to require surgery.

INTRODUCTION: The management of open tibial shaft fractures remains challenging. Intramedullary nailing and external fixation are the most commonly used fixation techniques although the optimal fixation technique remains unresolved. In this article the outcomes of these two surgical techniques are compared. METHODS: A comprehensive literature search was conducted through MEDLINE(®) using Ovid(®) and MeSH (Medical Subject Heading) terms for articles published in the English literature between 1999 and 2009. The outcome measures compared were time to fracture union, infection rates and complications. RESULTS: Forty-one studies were identified, of which only three met the inclusion criteria. The average time to union was variable. Delayed union and non-union appeared to be more prevalent in the external fixator group although this was not statistically significant. Both techniques were associated with secondary procedures as well as infection. CONCLUSIONS: The current literature indicates little evidence to suggest the superiority of one fixation technique over another for open tibial fractures.

We studied calcium (Ca), magnesium (Mg) mass transfer (MT) in 10 and lactate balance in 5 CAPD patients using standard dialysis solution [(ST) (Ca 1.75 mmol/l; Mg 0.75 mmol/l; lactate 35 mmol/l)] and with reduced Ca/Mg, high lactate solution [(LC) (1.25 mmol/l; 0.25 mmol/l; 40 mmol/l respectively)]. Exchanges were performed with 1.36% and 3.86% glucose solutions. MT was calculated as mmol/exchange. Ca MT was +0.96 and +0.39 with ST 1.36% and 3.86% glucose respectively. Serum ionised Ca (iCa++) levels were less than fluid Ca during these exchanges. With LC 1.36% glucose it was -0.66 when ICa++ was more than dialysate Ca, but +0.66 when iCa++ was less than dialysate Ca. Ca MT was negative with LC 3.86% glucose irrespective of iCa++ levels. All patients were hypermagnesaemic (mean 1.24 mmol/l. Mg MT was +0.21 and -0.04 with ST 1.36% and 3.86% glucose respectively and -0.62 and -1.13 with LC 1.36% and 3.86% glucose respectively. The difference between mean lactate gain and bicarbonate loss was less (-0.4) during exchange with LC 1.36% glucose. Mean plasma TCo2 and plasma pH did not differ between ST and LC solutions. We conclude that reduced Ca/Mg, high lactate solutions should reduce hypercalcaemia/magnesaemia and maintain a better acid base balance in CAPD patients who may require Ca/Mg containing phosphate binders.
