Do patients with diabetes wear shoes of the correct size?

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 11 2007
S. J. Harrison
Summary Background:, Fifteen per cent of patients with diabetes will develop a foot ulcer at some point in their life. Ill-fitting footwear frequently contributes to foot ulceration. A good fitting shoe is an essential component in the management of the diabetic foot. The objective of this study was to assess the feet and footwear of patients with diabetes to determine whether they are wearing the correct-sized shoes. Methods:, One-hundred patients with diabetes who were attending the general diabetic clinic had their foot length measured using a ,Clarks' shoe shop device and foot width using a pair of callipers. Measurements were taken whilst seated and standing. Shoe dimensions were also assessed by recording the manufactured shoe length and using callipers to assess shoe width. A calibrated measuring stick standardised shoe lengths. Neurovascular status and the presence of deformities in the foot were also recorded. Results:, One-third of diabetic patients were wearing the correct shoes on either foot whilst seated or whilst standing. However, only 24% of patients were wearing shoes that were of the correct length and width for both feet whilst seated and 20% upon standing. Seventeen per cent of patients appeared in both groups. No significance was found between any other variables, such as sensory neuropathy. Conclusions:, Many patients with diabetes wear shoes that do not fit, particularly, shoes that are too narrow for their foot width. Assessing the appropriateness of footwear maybe an important part of foot examination. [source]


Emergency Thoracic Ultrasound in the Differentiation of the Etiology of Shortness of Breath (ETUDES): Sonographic B-lines and N-terminal Pro-brain-type Natriuretic Peptide in Diagnosing Congestive Heart Failure

ACADEMIC EMERGENCY MEDICINE, Issue 3 2009
Andrew S. Liteplo MD
Abstract Objectives:, Sonographic thoracic B-lines and N-terminal pro-brain-type natriuretic peptide (NT-ProBNP) have been shown to help differentiate between congestive heart failure (CHF) and chronic obstructive pulmonary disease (COPD). The authors hypothesized that ultrasound (US) could be used to predict CHF and that it would provide additional predictive information when combined with NT-ProBNP. They also sought to determine optimal two- and eight-zone scanning protocols when different thresholds for a positive scan were used. Methods:, This was a prospective, observational study of a convenience sample of adult patients presenting to the emergency department (ED) with shortness of breath. Each patient had an eight-zone thoracic US performed by one of five sonographers, and serum NT-ProBNP levels were measured. Chart review by two physicians blinded to the US results served as the criterion standard. The operating characteristics of two- and eight-zone thoracic US alone, compared to, and combined with NT-ProBNP test results for predicting CHF were calculated using both dichotomous and interval likelihood ratios (LRs). Results:, One-hundred patients were enrolled. Six were excluded because of incomplete data. Results of 94 patients were analyzed. A positive eight-zone US, defined as at least two positive zones on each side, had a positive likelihood ratio (LR+) of 3.88 (99% confidence interval [CI] = 1.55 to 9.73) and a negative likelihood ratio (LR,) of 0.5 (95% CI = 0.30 to 0.82), while the NT-ProBNP demonstrated a LR+ of 2.3 (95% CI = 1.41 to 3.76) and LR, of 0.24 (95% CI = 0.09 to 0.66). Using interval LRs for the eight-zone US test alone, the LR for a totally positive test (all eight zones positive) was infinite and for a totally negative test (no zones positive) was 0.22 (95% CI = 0.06 to 0.80). For two-zone US, interval LRs were 4.73 (95% CI = 2.10 to 10.63) when inferior lateral zones were positive bilaterally and 0.3 (95% CI = 0.13 to 0.71) when these were negative. These changed to 8.04 (95% CI = 1.76 to 37.33) and 0.11 (95% CI = 0.02 to 0.69), respectively, when congruent with NT-ProBNP. Conclusions:, Bedside thoracic US for B-lines can be a useful test for diagnosing CHF. Predictive accuracy is greatly improved when studies are totally positive or totally negative. A two-zone protocol performs similarly to an eight-zone protocol. Thoracic US can be used alone or can provide additional predictive power to NT-ProBNP in the immediate evaluation of dyspneic patients presenting to the ED. [source]


Bedside Ultrasound Diagnosis of Clavicle Fractures in the Pediatric Emergency Department

ACADEMIC EMERGENCY MEDICINE, Issue 7 2010
Keith P. Cross MD
ACADEMIC EMERGENCY MEDICINE 2010; 17:687,693 © 2010 by the Society for Academic Emergency Medicine Abstract Objectives:, Clavicle fractures are among the most common orthopedic injuries in children. Diagnosis typically involves radiographs, which expose children to radiation and may consume significant time and resources. Our objective was to determine if bedside emergency department (ED) ultrasound (US) is an accurate alternative to radiography. Methods:, This was a prospective study of bedside US for diagnosing clavicle fractures. A convenience sample of children ages 1,18 years with shoulder injuries requiring radiographs was enrolled. Bedside US imaging and an unblinded interpretation were completed by a pediatric emergency physician (EP) prior to radiographs. A second interpreter, a pediatric EP attending physician with extensive US experience, determined a final interpretation of the US images at a later date. This final interpretation was blinded to both clinical and radiography outcomes. The reference standard was an attending radiologist's interpretation of radiographs. The primary outcome was the accuracy of the blinded US interpretation for detecting clavicle fractures compared to the reference standard. Secondary outcome measures included the interrater reliability of the unblinded bedside and the blinded physicians' interpretations and the FACES pain scores (range, 0,5) for US and radiograph imaging. Results:, One-hundred patients were included in the study, of whom 43 had clavicle fractures by radiography. The final US interpretation had 95% sensitivity (95% confidence interval [CI] = 83% to 99%) and 96% specificity (95% CI = 87% to 99%), and overall accuracy was 96%, with 96 congruent readings. Positive and negative predictive values (PPVs and NPVs, respectively) were 95% (95% CI = 83% to 99%) and 96% (95% CI = 87% to 99%), respectively. Interrater reliability (kappa) was 0.74 (95% CI = 0.60 to 0.88). FACES pain scores were available for the 86 subjects who were at least 5 years old. Pain scores were similar during US and radiography. Conclusions:, Compared to radiographs, bedside US can accurately diagnose pediatric clavicle fractures. US causes no more discomfort than radiography when detecting clavicle fractures. Given US's advantage of no radiation, pediatric EPs should consider this application. [source]


Olanzapine versus Droperidol for the Treatment of Primary Headache in the Emergency Department

ACADEMIC EMERGENCY MEDICINE, Issue 9 2008
Chandler H. Hill MD
Abstract Objectives:, The objective was to determine if there is a difference in pain relief or frequency and severity of side effects in emergency department (ED) patients with primary headache treated with either intramuscular (IM) olanzapine or IM droperidol. Methods:, This was a prospective, randomized nonblinded clinical trial of adult ED patients undergoing treatment for suspected primary headache. Consenting patients were randomized to receive either droperidol 5 mg IM or olanzapine 10 mg IM. Prior to receiving treatment, patients were asked to complete a 100-mm visual analog scale (VAS) describing their pain and a 4-point verbal rating scale (VRS) describing their pain as none, mild, moderate, or severe. Patients also completed a 100-mm VAS describing their level of nausea. Pain and nausea measurements were repeated 30 and 60 minutes after medication administration. Patients also completed the Barnes Akathisia Scale (BAS) 30 and 60 minutes after medication administration. Descriptive statistics were used as appropriate. Pain relief was compared both in terms of the decrease in VAS scores and in the proportion of patients who reported moderate or severe pain whose report later changed to mild or no pain. Results:, One-hundred patients were enrolled; 13 were withdrawn before administration of the study medication, 8 in the droperidol group and 5 in the olanzapine group, leaving 87 patients for analysis. Forty-two patients received droperidol and 45 received olanzapine. In the droperidol group, 35/40 (87.5%) patients who had reported moderate or severe pain at baseline reported mild or no pain at 60 minutes. In the olanzapine group, 38/44 (86.4%) reported this change (p = 0.89). The mean percent change from baseline VAS pain score at 60 minutes was ,37% (95% CI = ,84% to 11%) for droperidol and ,37% (95% CI = ,64% to 10%) for olanzapine (p = 0.30). The mean percent change from baseline for the VAS nausea score was ,59% (95% CI = ,70% to ,47%) for droperidol and ,64% (95% CI = ,77% to ,51%) for olanzapine (p = 0.83). There was no difference in any report of akathisia by the BAS between the groups (p = 0.63). Conclusions:, Both olanzapine and droperidol are effective treatments for primary headaches in the ED. No significant differences were found between the medications in terms of pain relief, antiemetic effect, or akathisia. Olanzapine may be used to treat primary headache and it is an effective alternative to droperidol. [source]


Randomized Clinical Trial of Propofol Versus Ketamine for Procedural Sedation in the Emergency Department

ACADEMIC EMERGENCY MEDICINE, Issue 6 2010
James R. Miner MD
Abstract Objectives:, The objective was to compare the occurrence of respiratory depression, adverse events, and recovery duration of propofol versus ketamine for use in procedural sedation in the emergency department (ED). Methods:, This was a randomized nonblinded prospective clinical trial of adult patients undergoing procedural sedation for painful procedures in the ED. Patients with pain before the procedure were treated with intravenous (IV) morphine sulfate until their pain was adequately treated at least 20 minutes before starting the procedure. Patients were randomized to receive either propofol 1 mg/kg IV followed by 0.5 mg/kg every 3 minutes as needed or ketamine 1.0 mg/kg IV followed by 0.5 mg/kg every 3 minutes as needed. Doses, vital signs, nasal end-tidal CO2 (ETCO2), and pulse oximetry were recorded. Subclinical respiratory depression was defined as a change in ETCO2 of >10 mm Hg, an oxygen saturation of <92% at any time, or an absent ETCO2 waveform at any time. Clinical interventions related to respiratory depression were noted during the procedure, including the addition of or increase in the flow rate of supplemental oxygen, the use of a bag-valve mask apparatus, airway repositioning, or stimulation to induce breathing. After the procedure, patients were asked if they experienced pain during the procedure and had recall of the procedure. Physicians were asked to describe any adverse events or the occurrence of recovery agitation. Results:, One-hundred patients were enrolled; 97 underwent sedation and were included in the analysis. Fifty patients received propofol and 47 received ketamine. Subclinical respiratory depression was seen in 20 of 50 patients in the propofol group and 30 of 47 patients in the ketamine group (p = 0.019, effect size 22.8%; 95% CI = 4.0% to 43.6%). Clinical interventions related to respiratory depression were used in 26 of 50 propofol patients and 19 of 47 ketamine patients (p = 0.253, effect size = ,13.7%; 95% CI = ,33.8% to 6.4%). The median times of the procedures were 11 minutes (range = 4 to 33 minutes) for the ketamine group versus 10 minutes (range = 5 to 33 minutes) for the propofol group (p = 0.256). The median time to return to baseline mental status after the procedure was completed was 14 minutes (range = 2 to 47 minutes) for the ketamine group and 5 minutes (range = 1 to 32 minutes) for the propofol group (p < 0.001). Pain during the procedure was reported by 3 of 50 patients in the propofol group and 1 of 47 patients in the ketamine group (effect size = ,3.9%, 95% confidence interval [CI] = ,11.9 to 4.1). Recall of some part of the procedure was reported by 4 of 50 patients in the propofol group and 6 of 47 patients in the ketamine group (effect size = 4.8%, 95% CI = ,7.6% to 17.1%). Forty-eight of 50 procedures were successful in the propofol group and 43 of 47 in the ketamine group (p = 0.357, effect size = 0.3%; 95% CI = ,7.8% to 8.4%). Recovery agitation was reported in 4 of 50 in the propofol group and 17 of 47 in the ketamine group (effect size = 28.2%, 95% CI = 12.4% to 43.9%). Conclusions:, This study detected a higher rate of subclinical respiratory depression in patients in the ketamine group than the propofol group. There was no difference in the rate of clinical interventions related to respiratory depression, pain, or recall of the procedure between the groups. Recovery agitation was seen more frequently in patients receiving ketamine than in those receiving propofol. The time to regain baseline mental status was longer in the ketamine group than the propofol group. This study suggests that the use of either ketamine or propofol is safe and effective for procedural sedation in the ED.
