title: The prevalence of neuropathic foot ulceration in Sri Lankan diabetic patients.
abstract: OBJECTIVE
  To determine the prevalence of diabetic neuropathy and neuropathic ulceration among patients with non-insulin dependent diabetes (NIDDM) attending a Sri Lankan diabetic clinic.
  
  
  METHODS
  The diabetic clinic of the General Hospital Colombo (Sri Lanka National Hospital).
  
  
  METHODS
  Five hundred randomly selected diabetic patients (mean age 47.4 SD 17.59 years, 275 were males, mean duration of diabetes 5.29, SD 6.44 years) were screened for diabetic neuropathy using a neuropathy symptom score (NSS) neurological disability score (NDS) and pressure preception threshold using Semmes Weinstein monofilaments.
  
  
  RESULTS
  Patients with neuropathy were older (mean 55.69 years SD 14.16) than those who did not (mean 47.1 years, SD 15.05 p = 0.001) and had diabetes for a longer period (mean 7.5, SD 8 years vs 4.8 SD 5.66, p = 0.002). 123 (30.6%, 95% CI 28-32%) patients had neuropathy according to the criteria used. 51(10.2%, 95% CI 8.2-12.2%) had a foot ulcer, a history of foot ulceration or a lower extremity amputation due to neuropathic ulceration. 26(5.1%, 95% CI 3.2-7%) patients had neuropathic foot ulcers at presentation and a further 14 (2.8%, 95% CI 1.4-4.2%) had developed an ulcer within one year of diagnosis of diabetes. 24 (4.8%, 95% CI 3-6.8%) had a history of lower extremity amputation.
  
  
  CONCLUSIONS
  Neuropathic ulceration is a significant cause of morbidity in patients with NIDDM. One third of all NIDDM patients attending the clinic had a risk of foot ulceration. Preventive foot care programmes should be implemented at all diabetic clinics in Sri Lanka.
