Socioeconomic profile of diabetic patients with and without foot problems

Introduction: To identify the differences in a socioeconomic profile between two cohorts of diabetic patients – one with diabetic foot problems and another without diabetic foot problems. Materials and methods: The cohort with diabetic foot problems (including cellulitis, abscess, osteomyelitis, septic arthritis, gangrene, ulcers, or Charcot joint disease) consisted of 122 diabetic patients, while the other cohort without foot problems consisted of 112 diabetic patients. Both were seen at the National University Hospital from January to April 2007. A detailed protocol was designed and the factors studied included patient profile, average monthly household income, education, compliance to diabetic medication, attendance at clinics for diabetic treatment, exercise, smoking, alcohol consumption, gender, and glycosylated haemoglobin (HbA1C) level. These were studied for significant differences using univariate and stepwise multivariate logistic regression analysis. Results: With multivariate analysis, Malay ethnicity (p<0.001), education of up to secondary school only (p=0.021), low average monthly household income of less than SGD $2,000 (p=0.030), lack of exercise (at least once a week, p=0.04), and elevated HbA1C level (>7.0%; p=0.015) were found to be significantly higher in the cohort with diabetic foot problems than the cohort without. Conclusions: There are significant differences in the socioeconomic factors between diabetic patients with diabetic foot problems and those without

Operative exposure and management of axillary vessel injuries

Axillary vessel injuries are uncommon and challenging injuries encountered by trauma surgeons. Proximity of this vessel to other adjacent veins including the axillary vein, brachial plexus and the osseous structures of the shoulder and upper arm account for a large number of associated injuries. Systematic review of the literature, with emphasis on the diagnosis, treatment and outcomes of these injuries, incorporating the authors' experience. Although uncommon, axillary arterial injuries can result in significant morbidity, limb loss and mortality. Early diagnosis and timely repair of the artery leads to good outcomes

Anatomical considerations of the internal iliac artery in association with the ilioinguinal approach for anterior acetabular fracture fixation

INTRODUCTION: Vascular injury may be encountered during an anterior approach to the pelvis or acetabulum-be it due to hematoma decompression, clot dislodgement during fracture manipulation, or iatrogenic. This can be associated with significant bleeding, hemodynamic instability, and subsequent morbidity. If the exact source of bleeding cannot be easily identified, compression of the internal iliac artery may be a lifesaving procedure. MATERIALS AND METHODS: We describe an extension of the lateral window of the ilioinguinal (or Olerud) approach elaborated on cadavers. RESULTS: The approach allows emergent access the internal iliac artery and intraoperative cross-clamping of the internal iliac vessels to control bleeding. CONCLUSION: The approach allows rapid access to the internal iliac artery. The surgeon should be familiar, however, with the surgical anatomy of this region to avoid potential injury to the ureter, peritoneum, lymphatics, and sympathetic nerves overlying the vessels when using the approach described
