Introduction Patients with chronic pain are more likely to
develop depression, which is associated with decreased function,
poorer treatment response and poor quality of life.
Objective This study aimed to determine the prevalence of
depression in patients with chronic pain.
Methods This descriptive cross-sectional study was conducted
among clinically diagnosed chronic pain patients from the pain
management ward of La Rabta hospital in Tunisia over a period
of six months.
Sociodemographic and clinical data were obtained from patients’
interviews and medical records.
The Beck depression inventory (BDI)was used for screening depres-
sion diagnoses and the Visual analogue scale (VAS) to assess the
severity of pain.
Results The sample included 102 patients with a mean age of
46.4 ± 10.4 years. The majority of the patients were females (72.5%,
n = 74), married (83.3%, n = 85) and being employed (58.8%, n = 60).
The prevalence of depression was (40.1%, n = 41). The mean dura-
tion of pain was 3.6 ±1.5 years. The severity of pain was mild in
28 cases (19.3%), moderate in 36 cases (31.3%) and severe in 38
cases (49.4%). Depression was significantly associated with the
duration of pain (P < 0.01). A positive correlation was observed
between pain severity assessed by VAS and BDI (r = 0.521, P = 001).
Depression was significantly associated with the duration of pain
(P < 0.01).
Conclusions Depression is frequent in patients who suffer from
chronic pain and it was significantly associated with the dura-
tion and the severity of pain. Antidepressants and psychological
therapies can be effective and should be delivered as part of a
multidisciplinary pain management plan.

Introduction Chronic pain and its estimate in general population
varies widely depending on the area and population studied. It is
concluded that exerts effects on both physical and mental health,
either in the patient or his family, in addition to its social cost
to influence activities of daily living, employment and economic
welfare of a significant proportion of the general population, con-
stituting one of the main reasons for medical consultation.
Aim Hypothesis: The painful perception is an operant behaviour.
Subjects Six subjects (S): 5 females and 1 male, aged between 56
and 72 years Diagnosis ICD-10: R52.2 chronic pain of neuropathic
origin. Material soundproof booth with audiometer Maico MA52.
Methods design Experimental single case.
Independent variable: behaviour modification treatment by dif-
ferential molding using auditory stimulation as discriminative
stimulus. Dependent variable: pain perception scale of 0-100%.
Analysiscomparisons using non-parametric test, significance at P
< 0.05.
Results (Media), SD (Standard deviation)
Conclusions Six replications of behavioural experiment were per-
formed. All show statistical significance. Generalization occurs in
83%. The hypothesis is confirmed and effectiveness of the treat-
ment protocol was concluded; however the line of work should
continue.

Objectives Study is aimed at evaluating the effects of ketamine
and magnesium sulphate on acute nociceptive pain in rats and
examination whether magnesium sulfate added to ketamine or
morphine-ketamine combination produces higher level of analge-
sia.
Methods Analgesic activity was assessed by tail-immersion test
in male Wistar rats (200–250 g).
