Acute dapsone poisoning is rare and such cases are either accidental or suicidal. Though accidental DDS poisoning are reported in children, the same is fairly uncommon in adults. Only 2 such cases are reported in India literature. We here report 4 cases of fatal sucidial DDS poisoning in adults resulting death in 3 cases. The reported acute symptoms include nausea, vomiting, hyperexcitability followed by depression, Carpopedal spasm or convulsions. The most marked signs are dyspnoea and cyanosis. The symptoms are due to methaemoglobinaemia, and or sulphaemoglobinaemia. Normally dapsone induces red cell haemolysis and even with small therapeutic doses of 25-100 mg per day, and in toxic doses reduces the oxygen carrying capacity of blood and damages the red cells making them more vulnerable for haemolysis. The peculiarity of the presentation in this series are manifestation of severe haemorrhagic episode in one case and progressive jaundice in another besides cyanosis. None of the cases had carpopedal spasm or convulsion. Out of four cases three died inspite of intensive care, intravenous vitamin C, exchange transfusion (2 cases) and other supportive measures. Intravenous methylene blue could not be used in these cases due to non-availability.

Depression in PHA-induced lymphocyte transformation in peripheral blood has been observed in 15 healthy volunteers after administration of DDS (100 mg/day) for seven days. In vitro culture of lymphocytes obtained from these volunteers in DDS-free normal AB serum has not altered the blast cell numbers. Lymphocytes of these volunteers have been found to contain a significant amount of DDS, ranging from 0.42 to 3.2 micrograms per 10.6 lymphocytes.

We tried to demonstrate that the cell kinetics-directed chemoendocrine therapy is more effective on hormone dependent breast cancer than empirical combination of the endocrine therapy and chemotherapy. Cell kinetics of each tumor was measured by flow cytometric analysis. Estrogen dependent human breast cancer cell line MCF-7 was used in vitro. In vivo, androgen dependent SC-115 carcinoma was transplanted to DDS mice. In vitro, tamoxifen was administered as the endocrine therapy. In vivo, we carried out testectomy on DDS mice. Effect of the endocrine therapy on the cell kinetics of the tumor was thought to be G1-S depression. High density 5FU was administered as the chemotherapeutic agents, whose content was 1 microgram/ml in vitro and 40 mg/kg in vivo. 5FU brought temporary decrease of cells in S phase. Only anteceding 5FU administration had synergistic effect in combination of 5FU and the endocrine therapy. 5FU was convinced to act more effectively on cells in S phase, so it was shown that cell kinetics-directed schedule was superior to the empirical treatment schedule in chemoendocrine therapy.

The influence of DDS on PHA-induced lymphocyte transformation was investigated in leukocyte cultures from two samples of healthy Caucasoid individuals. In one sample the sulfone-treated cultures differed from the controls in that they contained 0.4 mug/ml of other sample, the treated cultures contained DDS in concentrations of 4 mug/ml, 8 mug/ml and 16 mug/ml. The frequency of lymphocyte transformation induced by PHA was significantly reduced by DDS in all concentrations used. The data obtained are a strong indication that the plasma levels of dapsone among leprosy patients may contribute to the depression of the blastogenic capacity of their lymphocytes when stimulated by PHA.

PHA-induced blastoid transformation of lymphocytes was studied in 29 contacts of leprosy patients. 21 contacts taking DDS as prophylaxis showed significant depression of lymphocyte transformation while 8 contacts not taking DDS showed no depression as compared to controls. DDS thus has an inhibitory effect on cell mediated immune response.

Efforts to examine the process and risk of developing chronic back pain have relied generally upon retrospective study of individuals with already established pain. In an alternative approach to understanding the clinical course and evolution of low back disorders, a cohort of 76 men experiencing their first episode of back pain was assessed prospectively at 2, 6 and 12 months following pain onset. Standard measures of pain (Descriptor Differential Scale: DDS), disability (Sickness Impact Profile: SIP), and distress (Beck Depression Inventory: BDI) were employed to classify the sample into five groups: Resolved, Pain Only, Disability/Distress Only, Pain and Mild Disability/Distress, and Clinical Range. At both 6 and 12 months post pain onset, most (78%, 72% respectively) of the sample continued to experience pain. Many also experienced marked disability at 6 months (26%) and 12 months (14%). At 12 months, no participants had worsened relative to the 2-month baseline. Doubly multivariate analyses of variance (MANOVAs) were employed to compare baseline groups (Pain Only, Pain and Mild Disability/Distress, Clinical Range) on the DDS, SIP, and BDI across time. The group by time interaction from 2 through 12 months was reliable, with greatest change occurring in the Clinical Range group in disability and distress; interestingly, the decrease in pain was comparable among all groups. Follow-up tests across measures demonstrated greater change in the early (2-6-month) interval and relative stability in the later (6-12-month) interval. Comparison of those classified as 'improvers' with those who did not improve from 2 to 12 months showed similar findings. The clinical course of first onset back pain may be prolonged for many patients, and involves a continuum of related disability and distress. Individuals at risk for marked symptoms 1 year after an initial episode of back pain can be identified early, and prompt treatment might reduce the risk of pain chronicity.

This study evaluated a theoretically and empirically based model of the progression of acute neck and back pain to chronic pain and disability, developed from the literature in chronic pain, cognition, and stress and trauma. Clinical information and standardized psychosocial measures of cumulative traumatic events exposure (TLEQ), depressed mood (CES-D), pain (DDS), physical disability (PDI), and pain beliefs (PBPI) were collected at baseline from 84 acute back pain patients followed at an Acute Back Clinic over 3 months. Path analysis was used for the longitudinal prediction of perceived pain and disability. The predictive model accounted for 26% of the variance in persistent pain intensity and 58% of the variance in perceived physical disability at 3 months. Greater exposure to past traumatic life events and depressed mood were most predictive of chronic pain; depressed mood and negative pain beliefs were most predictive of chronic disability. More cumulative traumatic life events, higher levels of depression in the early stages of a new pain episode, and early beliefs that pain may be permanent significantly contribute to increased severity of subsequent pain and disability. Replication in a larger sample is desirable to confirm these paths. Early detection of elevated depressive symptoms and high trauma exposure may identify individuals at greater risk for developing chronic pain syndromes who may benefit from early multidisciplinary intervention.

Our aim was to determine the effect of risperidone monotherapy treatment on disability and on the quality of life of 318 schizophrenic outpatients who had been previously treated with other neuroleptics. Patients were assessed at baseline 2, 4 and 8 months using the BPRS, CGI, WHO/DDS and SF-36. BPRS scores showed a significant decrease at month 2, both in the total score and in each of the three clusters, negative, positive and depression/anxiety. WHO/DDS scores significantly decreased both in the overall score (from 51.8 to 37.4, P < 0.0001) and in the four dimensions. SF-36 scale scores and summary measures showed a significant improvement after 8 months of risperidone treatment. Risperidone long-term treatment (8 months) has a positive effect on clinical and on psychosocial outcomes. Females, paranoids patients and patients without history of use-abuse of substances showed greater improvements in quality of life.

This study is an attempt to investigate validity and reliability of the Persian version of Death Depression Scale among male and female nurses at Jundishapur University of Medical Science and 2 private hospitals in Ahvaz, Iran, who were selected by a convenience sampling method after obtaining informed consent. They completed the Death Depression Scale-Revised (DDS-R), Death Anxiety Scale, Death Obsession Scale, as well as Short-Form of Beck Depression Questionnaire (BDI-13). The results of exploratory factor analysis on DDS-R identified 3 factors. Cronbach's alpha coefficient was 0.93 for the entire measure (19 items), with alphas ranging from .80 to .94 for the individual factors. Indices of concurrent validity for this scale with Death Anxiety, Death Obsession Scales, and BDI-13 were all significant (p < 0.001). Given the validity and reliability of the DDS-R, this scale can be used in clinical settings and research studies.

Type 2 diabetes mellitus (T2DM) brings about an increasing psychosocial problem in adult patients. Prevalence data on and associated factors of diabetes related distress (DRD) and depression have been lacking in Asia. This study aimed to examine the prevalence of DRD and depression, and their associated factors in Asian adult T2DM patients. This study was conducted in three public health clinics measuring DRD (Diabetes Distress Scale, DDS), and depression (Patient Health Questionnaire, PHQ). Patients who were at least 30 years of age, had T2DM for more than one year, with regular follow-up and recent laboratory results (< 3 months) were consecutively recruited. Associations between DRD, depression and the combination DRD-depression with demographic and clinical characteristics were analysed using generalized linear models. From 752 invited people, 700 participated (mean age 56.9 years, 52.8% female, 52.9% Malay, 79.1% married). Prevalence of DRD and depression were 49.2% and 41.7%, respectively. Distress and depression were correlated, spearman's r = 0.50. Patients with higher DRD were younger (OR 0.995, 95% CI 0.996 to 0.991), Chinese (OR 1.2, 95% CI 1.04 to 1.29), attending Dengkil health clinic (OR 1.1, 95% CI 1.00 to 1.22) and had higher scores on the PHQ (OR 1.1, 95% CI 1.04 to 1.06). Depression was less likely in the unmarried compared to divorced/separately living and those attending Dengkil health clinic, but more likely in patients with microvascular complications (OR 1.4, 95% CI 1.06 to 1.73) and higher DDS (OR 1.03, 95% CI 1.02 to 1.03). For the combination of DRD and depression, unemployment (OR 4.7, 95% CI 1.02 to 21.20) had positive association, whereas those under medical care at the Salak health clinics (OR 0.28, 95% CI 0.12 to 0.63), and those with a blood pressure > 130/80 mmHg (OR 0.53, 95% CI 0.32 to 0.89) were less likely to experience both DRD and depression. DRD and depression were common and correlated in Asian adults with T2DM at primary care level. Socio-demographic more than clinical characteristics were related to DRD and depression.
