The introduction and conclusion of the chapter
As stated in the aim and objectives in chapter 1, the first objective of this PhD research project is to critically review the literature on PDN with focus on its nature and diagnosis and on the screening tools for neuropathic pain, in order to identify the methodology to be used to estimate the point prevalence of PDN in Libyan diabetic patients, which is the main aim in this thesis. This chapter provides a critical overview of PDN. It describes and discusses the published findings in several key articles in order to define the condition, describe the entities that are categorised together as PDN, and explain its pathophysiology and diagnosis in clinical settings. Such information is indispensable for a critical appraisal of the screening for PDN using symptoms-based questionnaires that can be used for surveys in the limited resources setting of the Libyan healthcare environment.
As it is also important to distinguish between painful and painless neuropathies, this chapter includes brief discussion of the definitions of pain used in this thesis. Finally, it will be argued that there is a need for a systematic review of the prevalence of PDN in the MENA region as a whole and in Libya in particular.
KEY: Chapter content Rationale
Diabetic neuropathy is the most common complication of diabetes, and its pathophysiology likely resembles that of PDN. In the MENA region, PDN is understudied and requires further investigation ….
LANSS, S-LANSS and DN4 can all be used as screening tools for estimating the prevalence of PDN. However, the arguments for using LANSS or S-LANSS have been discussed in this chapter and the conclusion is that the measurement properties of these questionnaires need to be evaluated in the new target population, i.e., Libyans with PDN.
